Again Ram Upgrade

I read some other questions about Ram upgrade in his section but no clearly answered my question.
I have a first intel generation Mac mini (1,667) Core Duo with 512 MB Ram, now I want to upgrade it to at least 2 GB (the official maximum). The question is, what is the better solution, buy a 2 GB chip and keep 256 MB on the second Ram slot (the 512 Mb comes in pairs, 256 + 256) or is 1GB + 1 GB (paired Ram) the better solution ? Or maybe it is impossible to run a 2 GB Ram (single chip) in my Mac mini ?

Andy is correct. For your first gen Intel Mini, two 1-Gig sticks of RAM is the only way to go, if you "want to upgrade it to at least 2 GB".
The only Mini that can address more than 2 gigabytes of RAM is the currently manufactured Intel Core 2 Duo Mini, which can address up to 3 gigs of RAM.

Hard Drive and RAM upgrades for latest 15" MBP

I'm minutes from ordering a new MBP. Only concerns are whether I get hte Apple upgrades or shop around.
I like this Hard Drive...
http://www.compu2000.com/index.php?l=product_detail&p=6433
And this RAM upgrade...
http://www.a-power.com/product-10937-311-4
If these are equivalent to the apple options I can save hundreds and get a 320 GB drive, which will make a great portable.
So, does my plan hold water?

You're on your own for support when you do your own upgrades like this, but generally speaking, it works fine.
Note that HDD is less risky than RAM. With RAM you run the risk of unstable behavior that is tougher to diagnose. That said, a quality RAM upgrade and some initial testing with any of many available tools is as good as a factory build.
HDD upgrades are less risky, and I've upgraded (well, replaced after HDD death) ones in my MBPs many many times. I crunch my hard drives more than normal and have to generally replace them about every year. Some of the MBPs don't make this easy, and prepare to get all sorts of cozy with little 0 and 1 sized Phillips screwdrivers and some T6 as well, but it is doable (just not quite for the truly faint of heart).
Again, you're on your own for support once you do this, so weigh that in your decision.

24" iMac (Primo 2009) strange RAM upgrade issue

I have a 24" iMac (Primo 2009) at work. I been granted a RAM upgrade by the IT department and have received 2 indentical 4 GB modules.
The 24" iMac (Primo 2009) uses 1066 MHz DDR3 modules and supports up to 8 GB RAM in 2 slots. I have purchased RAM from this source http://www.dustin.dk/product/5010642132/corsair-4gb-ddr3-1066mhz-1x4gb-so-dimm-i mac-macbook-macpro/#intcmp=searchProvider_SiteSeeker (Corsair Mac Memory so they SHOULD be fine.)
Here's the issue:
I had 2x 2GB modules. I have taken both out.
I have inserted the new 2x 4GB modules but the machine refuses to boot. It gives off 3 beeps-interval-3 beeps-interval (repeats).
I took out one of the 4GB modules from slot B. It boots.
I inserted the one I removed in slot B again so we're back at 8GB. same beeps. No boot.
I switched the 2 4GB modules from slot A+B around. Now beep-interval-beep-interval (repeats) No boot.
I inserted one 4 GB in slot 1, and one of the old 2 GB in slot 2. It boots with 6GB RAM.
I inerted only the one that won't boot when in slot B in slot A, beep-interval-beep-interval (repeats) No boot.
OK - so logical deduction tells me one of the new 4GB RAM modules is defective. No matter what configuration, booting fails with that specific module inserted, though there are different beeps. I also know tha both slots work since the machine works with 6 GB RAM (2+4).
So I called Dustin, and since we're a big customer they sent a new moduel for free. But, I have the same isssue with the new module!! What are the chances I have recived 1 working and 2 defective modules? not big right? So my iMac seems fine with the old 2GB modules and one of the new 4 GB modules, but says no to the 2 other 4GB modules.
YES - I have tried resetting PRAM and SMC to no avail. Any clue?

Switched the 2 modules around, so there's now a 2GB in slot A and a 4 GB in slot B. Still works fine

Kernel Power error after Win 7 and RAM upgrade

Hello,
I posted earlier on the subject of win7 and ram upgrades. I did both and it seemed to go fine. I did the ram first ... replaced a 667Mhz 1gb with a 800Mhz 2gb. A couple of days later the computer just shut itself down and restarted. Since then it has done it another 5 times, seemingly at random. Yesterday I decided to spend some time looking into it and found the 'event log'. All the shutdowns are recorded as 'critical'. A search on the web/here showed other occurences of the fault associated with drivers as much as anything.
After I did the win update I did update almost every driver with ones from this site.
Other than the shutdowns the only issues I have which are of very mild concern are the length of time the fingerprint reader takes to be present and that occasionally the cursor is unavailable for about a minute after logging on. When you try and control it it jumps about anywhere but where you want it to go. I rolled back the alps driver and that seems to have sorted the cursor issue.
So, details of the shutdown from the event log are as follows.

There's more (I've shown it all below) but it's not that important. When I looked into it I found details of the problem on the microsoft knowledge base. Its described here http://support.microsoft.com/kb/2028504.
I believe I fit into scenario 3 for cause and resolution.
So, it seems that win7 and mixed speed ram may be a problem on some computers ... probably only a tiny number, but it looks like the HP3507 is one of them. I did see somewhere that I could down speed from 667 to 266 which might help with memory compatability but I can't see anywhere on the the insydeH20 bios where to do it. BIOS is version F18 .... upgraded from F15 as part of the Win7/RAM ugrade.
Before I swap back to the 'old' memory I'll see if anybody here can come up with any ideas. It may be that I have to sell off the expensive 2gb memory (ddr2 800mhz 200 pin) for £39.99 from maplin at a bargain price and get 2gb of 667Mhz from somewhere.
The full 'detail' regarding the fault is below.
Bye for now.

Hi DWeiland and Schwede,
Thanks for your replies. Yes I did the runtime engine registry change and also mass compiled the LV7.1 folder and my sourcecode. I still see the problem as I have set the LV adapter as Lv 7.1.1 runtime engine. Now I have changed it to LV7.1 development system. With this setting, it is not giving any error. Thus I don’t see any problem now. The older version of the code had the adapter as the runtime engine for some reason, now I have changed the setting to the development system. I hope that it shouldn’t be a problem.
Thanks again!
Thank you,
Sasi

Mac pro 5,1 RAM Upgrade

I am planning to give my Mac Pro (Mid 2010) another RAM upgrade. As the official Kingston/Crucial DIMMs do not include 16GB DIMMs, I think of choosing Kingston Value RAM: ECC Registered (3x, 16GB, DDR3-1600, DIMM 240). Has anyone here in the forum tried these?
Thanks for your comments.

The biggest official Kingston part is KTA-MP1333/8g which is a single 8GB module.
For 16GB modules the main criteria are that
It must be registered memory - not buffered, this is more because there aren't any 16GB buffered DIMMS
You cannot mix registered and buffered so any other existing memory left fitted must also be registered, as it happens you are supposed to not mix 16GB with smaller sizes anyway
It should be 1333Mhz DDR3 although in theory 1066Mhz DDR3 would work, again I don't believe there are any 16GB 1066Mhz DIMMS
It should be ECC (error correcting)
CL9
The presence of a Thermal Sensor is apparently not compulsory, i.e. memory without it will work in a Mac Pro.
I have not used any 16GB DIMMS myself but other than OWC as per the link provided by Illaass, the following might be suitable
KVR13R9D4K4/64i - this is a kit of 4 x 16GB and this article has a post from someone who says they worked for them http://forums.macrumors.com/showthread.php?t=1493588
If you can find a kit of 2 x 16GB of the same type then logically they should also work, they would probably be KVR13R9D4K2/32i. As a reminder to do 64GB or more you need dual processors. The single processor model Mac Pro 2010 is limited to 48GB.
See http://www.kingston.com/datasheets/KVR13R9D4K2_32I.pdf

Display problem after RAM Upgrade to MS6712

Hi there,
after a RAM upgrade (512mb to 3GB) my PC has developed a display problem. The graphics are slow / rippled and video playback is very poor. In device manager no "display adapters" are present and there is also an error mesage referring to the VIA CPU to AGP2/AGP3.0 controller not having enough free resources to run due to a conflisct with VGAsave? I've downloaded the latest VIA chipset drivers to no effect?
System info: MS6712 MB, AMD Athlon 1.25GHZ, XP SP3.0

OK, here's the info on my PSU;
It's a Powerman FSP250-60GTU(PF). Input: 230V - 5A, 50Hz. Max Output: 250W
While I had the case open I took out 2 of the RAM modules and without making any other changes everything appeared to work fine with just the 1GB, so I tried putting 1 more back in to take it to 2GB and again all seems fine? Does this indeed point to my PSU then? If so and it works fine with 2GB should I be thankfull for a 512mb to 2GB upgrade and send the 3rd module back to Crucial??
Before I posted this thread I did run a memtest from Memtest86+ with all three modules installed and it came up with NO problems?
Re Henry's post, I searched using the format of the part no on the RAM modules themselves i.e. M368L2923FLN-CB3 and it took me here:
http://www.samsung.com/global/business/semiconductor/productListNonflexTable.do?fmly_id=118&sht_id=1
Other info on printed the modules themselves: 1GB DDR PC2700 CL2.5
According to Everest my CPU temp (with 2GB installed) is: 43 degrees (MOBO 30 degrees and HD 42 degrees) - do these seem normal?

Photoshop not registering my RAM upgrade.

Hi there. I recently doubled my RAM to 4GB but PhSp performance preference says 1634MBs are available. Is Photoshop not registering the RAM upgrade; is there a setting I can update?
My PC operating system registers the RAM upgrade under control panel and I've set the boot drive virtula memory to 500-1500MB.
Any ideas out there?

; I wish I could remember what it registered as available before the upgrade to knoe if it evens knows there's a difference! Thanks again!

I see you tagged PS CS 5.5 . Are you trying to use the 64-bit version?   If you only have 4GB on your machine then it is possible that your computer is reserving some of its memory for the operating system and PS puts a cap on how much it uses so as not to encumber your machine. At least that's my guess. I'm not as technically savvy on memory with PS as some others on this forum. But I do know that the 32-bit version of PS will NOT see above 4GB of RAM so try the 64-bit edition if you have a 64-bit OS.

Problems with RAM upgrade iMac G5 1.8GHz

Stuck - Need Help!
I've previously upgraded up iMac to 2 500Mb RAMs and felt recently that it needed that little bit extra, so I ordered two 1Gb chips from crucial.
Followed instructions to T, but with the two new chips in, the machine won't load.
Interestingly, it boots up with the following RAM combinations
old 500MB + new 1GB (in any combination) - recognised as 1.5GB
one new 1GB RAM (again either one) - recognised as 1GB
I spoke to crucial who said that as the RAMs work individually, there isn't a problem with them, it could be a Firmware issue. I've upgraded all my software, and don't know what to do next?
Anyone overcome a similar problem in the past?
Thanks

I'm experiencing something very similar to shaow. I'll share my experience in gory details - sorry for the long post but I've spent more hours trying to stabilize. I should have worked the hours at walmart and bought a new iMac with the money I could have earned
Anyway, here goes:
Two iMac G5 1.8Ghz 17" (both Fall 2005 model), will call one A and the other B.
Prior to attempting ram upgrade: A, config working fine: both a config using 1GB slot 1, 256MB slot 2 and a single 1 PC3200 1GB stick. OS X 10.4-10.5.7. No problems. I did have the motherboard replaced under warranty after having sleep problems - capacitors were expanded. No problems since that motherboard swap.
Prior to attempting ram upgrade: B, config working fine: 2 x 256MB sticks. OS X 10.3.9
Ordered 3 PC3200 400Mhz 1GB sticks from Data Memory Systems.
Upgraded A: Added 1GB stick = 2GB total
Upgraded B: Removed both 256MB sticks from B and added two 1GB sticks = 2GB total
Booted B, experienced gray screen of death with the multi-language crash message - somethign like: 'Please hold down the power button and restart'. Power cycled B, booted off a retail box DVD of OS X 10.5.6. Began upgrade to 10.5.6. Gray screen of death part way thru upgrade. Power cycled, gray screen of death again during early boot phase.
Decided to run tests on B. I could not locate the Apple Hardware Test (neither on system dvd 1 nor on a separate DVD). I resorted to using TechnoTools Deluxe which was included with AppleCare box. No hardware problems found including on the 2GB memory.
Removed both new 1GB sticks, pulled older working 1GB stick from A and installed into B. Completed upgrade with just 1GB memory on B to 10.5.6 and subsequently pulled down all updates for OS X 10.5.8. Powered down, added second 1GB stick to B, booted into 10.5.8 successfully. Repaired disk permissions, restarted. Began using applications, then after only about 5 minutes experienced gray screen of death. Powered down, removed new 1GB stick, replaced with one of the two remaining new 1GB sticks. Read about reseting PRAM/NVRAM. Followed steps to reset PRAM then decided to do the reset NVRAM within openfirmware. Started back up and logged into 10.5.8. Ran several applications - did not experience gray screen of death after about 20 minutes use. Have not had time for further tests on B yet.
Back to my saga with A (my original iMac G5 that was working fine with 1GB stick on 10.5.7):
Called Data Memory Systems and they sent me a replacement for the 'bad' 1GB stick.
While I was waiting for the new 1GB stick from DMS, I was struggling to get machine fully updated. Software Updater was failing with the weird network error (network was fine) and after following steps to troubleshoot, I backed up the user accounts and decided to reinstall OS X fresh from the 10.5.6 retail box (family license). Finally, I had OS X 10.5.8 all fully updated on the 1GB iMac G5 (A).
New memory arrived, installed 2nd 1GB stick. Booted up, immediately I got the gray screen of death. Restarted, booted up got about 5-15 minutes use then gray screen of death. Puzzled, I called DMS who said unlikely I got 2 bad sticks. They suggested I try memtest. So I did...
So on A, I first ran memtest from single user mode on the 2GB config. It crashed immediately with some 'Unexpected' error. Did not look like a memory error. I powered down, removed 2nd 1GB stick, and ran memtest from single user on the 1GB stick. Ran all tests 3x over a couple hours - no problems found. Retested after swapping the 1GB stick for the other. Both tested fine. Installed both sticks again and ran memtest all tests, one pass (didn't want another 6 hours lost) on the 2GB config, and all tests passed. Booted up and got gray screen of death - I don't recall if it was on bootup or after running but I ran fsck with no disk problems found, then restarted, logged in, ran disk utility to repair all permissions. Some repairs were made. Restarted A, reset PRAM and NVRAM again, booted successfully.
I haven't had much time to run extensively apps on A yet. It's sleeping as I type this on another mac. My next test will be to reset SMU.
I'm starting to wonder if the original iMac G5 has firmware problems that would prevent it from being unstable with two 1GB sticks??? My experience on two identical models of iMac G5 plus reading this post with VERY similar behaviors and after all the normal tests. I've concluded the memory is A-OK and something more sinister is lurking...
Any thoughts are appreciated.

U310 RAM Upgradable? Voided Warranty?

Hi --
I am a tentative Lenovo buyer and was am set on getting the U310 Ultrabook. I do notice though that it only has 4 GB of RAM. I would ideally like to upgrade this upon getting the laptop. Is this possible? I have researched it and cannot find any answers for this particular model. I just do not want to buy the laptop and find out that it does not have an extra slot to upgrade the RAM so I am stuck with 4 gig. If this is the case, then I may just spring the extra $100 or so and get the U410 Ultrabook.
Secondly, will doing anything like this by myself void the warranty? I certainly would not like that to happen.
Let me know and if anyone has any advice on the U series; I'm hoping to buy today before this sale is over.
Thanks!

I just upgraded and wanted to share some notes. The quick answers are:
- Yes, opening the case voids the warranty (and needs to be done carefully)
- Yes, the machine can run 8GB of RAM
- and (bonus) you can use the mSATA SSD drive as a regular SSD drive--and upgrade it as well
The only potential hiccup is that you may need to flash BIOS version 65CN21WW for the RAM upgrade to work. Initially my machine would not boot or POST with the 8GB stick. After flashing this version things went smoothly (aside from needing to re-apply BIOS settings to get Windows 8 to boot again).
Here's more details:
- my machine is the non-touch screen i3 based system
- I used the Crucial memory advisor to locate the 8GB stick of RAM and a 240GB mSATA SSD
- There are useful YouTube videos showing how to remove the back panel. Basically you pry off the rubber feet, unscrew the 4 screws you'll find, then (VERY) carefully work your way around the space between the back panel and the silver plastic
For my dual-boot setup:
- Fully shutdown Windows (being sure not to use Intel Rapid Start--you want it to be a complete shutdown)
- In the BIOS disable IRST
- Switch the drives to AHCI mode in the BIOS (you'll need to reload Windows after doing this)
From there I installed Windows 8.1 to a 250GB partition on the 500GB spindle drive. Ubuntu GNOME 13.10 went on the entire SSD, with the other 250GB of the spindle drive available for slower-speed storage. With my increased storage I'll be considering if both OS's should reside on the SSD for performance, with extra storage on the larger drive.

Poor performance despite RAM upgrade

Hi
I just upgraded my MAC MINI 2GB RAM to a total of 6GB RAM.
The MAC Mini definitely shows as having 6GB of RAM now but still it seems to struggle.
I have only one song (with about 10 tracks) in Garageband, there's no stuff on my desktop etc so the performance should be better but even now it seems to struggle and GB often freezes. I don't really see what the problem could be as like I said I have only one song in there that I am working on and surely my MAC should be able to handle a lot more than that without crashing and freezing.
Any ideas please?

Yes, I have tried it. This is not very practical however and the reason i got more RAM is so that I do not always have to lock tracks. It is impractical to lock tracks, especially while mixing. Every time I have to lock a track it takes at least 30 secs to lock it, that's why I stopped locking them.
I would have thought that 4GB more RAM would allow me the 'luxury' of not having to lock. However, locking does help performance but is a major pain.
And again, the whole reason i spent money on a RAM upgrade was so that I wouldn't always have to lock, so locking the tracks now would defeat the object.

Compaq Presario C303NR Doesn't Completely Start-up after New RAM Upgrade

Hello Paul,
This is Tammy. I finally made time this morning to upgrade the ram in my laptop, model C303nr. And, I'm in desparate need of help because something went horribly wrong.
The laptop boots up to my desktop, but then I get nothing but moving vertical lines, much like tv snow, but more structured. I've taken the new memory out a couple of times and tried to re-seated it, but I get the same results. Moreover, when I tried to put the old memory back in, the exact same thing happens. Have I completely broken my laptop?
Can you or someone out there please help me. This is my first attempt to do something like this and I feel absolutely heartsick over the results.
Clinging to hope for a fix,
Tammy
This question was solved.
View Solution.

Hi Paul,
After the other tech responded by asking me to connect the laptop to an external monitor to check the video card, I decided to take another go at the ram first. Note: My only external monitor is packed knee-deep in a storage room and would have been a nightmare to unearth, so going toe-to-toe again with the ram seemed considerably less challenging at that point.
I have a small hand-held vac that I use only for blowing dust off of figurines, so I pulled it out and blew the inside of the laptop out as best I could without taking the entire bottom cover off. Then I blew the old ram off for good measure. After I re-installed the old ram, the laptop booted and the screen about windows not shutting down properly came up. (Note: Because of my earlier problem with the ram, I had to do a hard shut-down.) Safe-mode was one of my options, so I chose it. After fully booting into safe-mode everything appeared okay... no vertical, moving, snowy lines. I shut the laptop down and then started it again in normal mode. (Note: Didn't use restart. Did it the long way.) The laptop booted fine again.
Somewhat encouraged, I decided to take a chance on the new ram. So I blew it off for good measure too and installed one stick. Restarted and everything worked just fine. Shut it down and started it again. Everything still okay. Blew the second stick off, installed it, and restarted the laptop... fully expecting something to go wrong here. Nothing did. Shut the laptop down and started it again. All surprisingly okay. I hadn't used this laptop since our previous modem/router went out, so I had to set-up wireless connection. All remained okay... and appears to still be okay. Currently running, though it is not the one I am typing this message with.
In summary, the only thing I can figure out is that I inadvertently introduced dust into either the ram seat or onto the ram itself. Or, that in spite of the ram appearing well seated to a novice, it wasn't. (I had read someone else's thread that indicated this as being a possibility.)
(Note: I went into such detail above in the event this thread might help someone else at a later date with his/her own ram upgrade problem.)
A much relieved and grateful...
Tammy

HP dv6-6c75sa Windows 7 64-bit RAM upgrade

I am running an HP dv6-6c75sa on Windows 7 Home Premium 64-bit, with an Intel Core i3-2350M processor. My installed software is a combination of 32- and 64- bit compatible.
When I purchased the computer, I installed a RAM upgrade which took the total onboard RAM to 8GB. Due to a system issue which I cannot now recall, a search query informed me that my system would only recognise 6GB of what I had installed.
My computer is now 2 years old, and to extend its lifespan, and help it keep up with a recent software install which it cannot seem to cope with (Native Instruments Traktor 2, and Kontrol S4; I would like to make a new RAM upgrade.
I think that the reason only 6GB of my 8GB installed was recognised, may have had something to do with the 32- vs. the 64-bit system, but I can't be sure.
I know that the maximum RAM for Windows 7 Home Premium is 16GB. What changes could I make now that would allow my system to work at or near 16GB of RAM capacity?
Also, where I have a mishmash of 32- and 64-bit software, on a clean install running 64-bit, I believe that I should be able to get all of my software running again. Are there any traps I should look out for that may hamper this.
Do you think that my processor is the thing that is limiting my RAM capacity?
I would appreciate your input.

Hi @hyfpxm ,
Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue about your HP Pavilion dv6-6c75sa Notebook and concerns with system recovery.
Here is a document on performing a system recovery. Here is a document on troubleshooting issues with performing a system recovery.
Always back up important information before attempting a recovery.
This system supports up to 8 GB DDR3 10600 1333-MHz and I would recommend 2- 4s. Here is a link to the manual page 60 for the memory. If the specs are correct for your memory I would reseat it.
Use the built-in Windows System Information utility to view information on Operating System, CPU type and speed, 32Bit or 64Bit design, and installed RAM memory. The section marked Find specifications using Windows System information.
Hope this helps.

Mac Mini RAM upgrade: failure after one week

my system:
Model Name:          Mac mini
Model Identifier:          Macmini5,2
Processor Name:          Intel Core i5
Processor Speed:          2.5 GHz
Number of Processors:          1
Total Number of Cores:          2
L2 Cache (per Core):          256 KB
L3 Cache:          3 MB
Memory:          4 GB
After severe performance problems with Aperture, I decided to go for an RAM upgrade to 2x4GB. Went to my (non-Apple) dealer, got me two DDR3 1333Mhz Samsung bricks and put them in. Worked like a chime. Startup went fine, RAM types shown in the Activity Monitor with plenty of free RAM and great performance... for a change.
After a week however my Mac froze. A restart gave me two beeps and a flashing light in front. Manual tells me 'wrong RAM type'. Same situation after replacing only one of the bricks.
A bit weird after a week of juicy operation?
Getting back the old RAM installed resulted in a working Mac - but with the limited memory obviously.
Will go back to the dealer and have the RAM replaced next week.
Ever heard about RAM failing after a well?
/thanks!

UPDATE:
right, I went back to my dealer and got the RAM sticks replaced. the miniMac booted up at the store and is now working fine again. Let's see for how long.
Size:          4 GB
Type:          DDR3
Speed:          1333 MHz
Status:          OK
Manufacturer:          0x80CE
Part Number:          0x4D34373142353237334348302D4348392020
Serial Number:          0x005001B9
I had checked the serial number and RAM chip IDs with the Samsung tool from their homepage. Looked just fine.
To my limited knowledge about Silicon production it would not be too easy to produce fake RAM sticks that
- are accepted by the HW check
- show the capacity as specified
- .. but fail after few days (haha!)
I will update you about the latest with this story.

Ram upgrade to 2GB - fan running faster

I have just upgraded my intel mac mini from 512 MB to 2 GB using a kingston upgrade kit (KTA-MB667K2/2G).
The system is performing a lot better but there is an annoying "trouble": when 2 GB are installed the fan is running more fast and more often then with 512MB.
During my tests, I have see that while using OS X the system is able to regulate the speed, it goes from very slow to very fast but it moves to fast more often then before and the system is definetly making more noise.
The bigger problem happens when booting using windows XP: when 2 GB of RAM are installed the fan is always running at top speed or near to top speed.
That is not happening while using the original 512 MB.
I have tried to reset the SMC by using the apple istructions here:
http://docs.info.apple.com/article.html?artnum=303446
but it didn't make any difference.
I have double checked all wires,I have switched from 512MB to 2 GB and from 2 GB to 512MB three times(!) but nothing has changed:
- when using 512MB fan runs slow;
- when using 2 GB fan is still able to change speed but is running fast more often.
Further more, to test, I have also left disconnected the fan speed cable in the front side, and in such way the fun starts at max speed and runs at fast speed all the time. So it is not a trouble with such connection.
Is that normal this behavior?
Does anybody have noticed any fan speed difference after RAM upgrade?
About BootCamp and XP running fan at max speed, could be that reinstall them could solve the "always on" fan trouble with 2 GB?
Thanks a lot for any help.

I have some updates about the problem.
I was thinking that it was a my fault about some missing setup needed when installing more ram to mac mini.
So, today, I have moved to a local apple center and I have asked them to install the RAM for me... they do, and it happens the same thing: the fun was running very fast quite often under OS X and was always fast under bootcamp-XP.
I have asked them why this happens and if that was normal, but they have no other mac mini with such amount of ram and they never see it before. They suggest me to test it for a week and eventually to give them the mac for a day to make some hardware tests.
Later, back into my office, the noise was too high and too annoying so I have called again apple to explain the situation.
They told me that they have no reports about similar problems, that it should not make more noise when adding RAM. They suggest me to try remove and reinstall better the RAMs or to try different RAMs (I am using kingston kit KTA-MB667K2/2G).
So I have also phoned to kingston support, and they say that it is a strange bahavior, that they don't have reports about that too. They are now investigating the problem and they let me know something in next days.
They also put to my attention the fact that the computer is able to see and work well with the 2GB memory, so the memory is working correctly. They think this is something related to apple hardware/firmware and could be that apple should fix it in next realases.
Unfortunatly, all this new infos and all the time lost for a "simple" memory upgrade didn't solve my troubles and I still cannot use the mac like I need.
So I have continued my tests by changing the kensington Dimms with other 2 GB dimms by Nanya technologies that were installed on my centrino duo notebook.
Mac mini was able to see and work well with them too, now the fun speed is a little bit slowly then using kingston ones but still more fast than with 512MB.
Bootcamp-XP is still not usable due to high fan speed and the high noise. OS X seems to control better the fan speed but it goes high there too for any little thing you do.
So I have made one more test suggested by kingston:
I have started mac mini while only one kingston dimm were inside.
In this way the mac mini was making some less noise that using the two nanya dimms, but it was still to high.
The last test I made was to check the cpu temperature with different amounts of RAM and results were interesting.
Using OS X with 512MB, the cpu temperature is about 33 C while iddle; if I try to start parallels desktop with guest windows XP, temperature goes up to 40 C and the fan is still running at quite low levels.
Instead, while 1 GB of RAM was installed, cpu iddle temperature was 35 C and starting parallels desktop will result in temperature levels till 50 C.
So there was a difference of about 10 C.
While doing these test I have left the mac mini open, so once stopped, I was able to quickly feel the RAM temperature with my finger and it was quite hot.
I didn't try temperature with both 2GB dimms, but I belive it will be surely more high.
So what I am thinking now is that probably apple is aware about higher temperature inside when using more RAM, so the bios starts the mac mini with the fun running faster because it detects the 2 GB memory.
OS X is able to control someway the fun so it is not always running fast (but quite often) while using boot camp with XP becomes impossible due to the fan always at max speed.
I don't think apple's rams could work at lower temperature than kingston ones, so the dubt now is that things are correct in this way.. so intel mac mini with 1/2GB could be a shame due to high level of fan noise... or... my mac mini has something wrong.
Is anybody here with a mac mini and 2 GB of RAM?
Anybody could make some test about that?
Thanks a lot for any help

Unstable Mac Mini 2011 after ram upgrade

I put in 8GB kit ram from Corsair. Every specific things is matching with Apple's requirement on ram upgrade. I got Corsair 8GB KIT DDR3 SO-DIMM, 1333Mhz. The first boot with the new ram was fine but after 10 minutes of normal using (Safari, Spotify) and testing open Photoshop CS5 it crashed.
I shut down the system and tried to take off the rams the put it in again just to make sure that they're there perfectly. Second boot, everythings seems work well but after a while, maybe 20 minutes, Safari crashed and a "crash log" is sending to Apple. Happened the same with Spotify, Photoshop when it was open. I couldn't reopen the programs so I did another reboot.
The third reboot, seems fine until 1h30min the whole system crashed, the computer is rebooting by itself and showing a message of "something is wrong with the system" so it needed a reboot.
And Safari crashed once again while I wrote this.
I hope someone can help me solve the problem. I'm running the lastest version of Lion Mountain (10.8.2), 2.5Ghz i5 mid 2011 Mac mini.

I have used Corsair RAMs on multiple Macs with
a lot of success (running a 16 gig on a 2011 Mini Server
I am currently typing this on). It may just be you got a bad
one. It happens. Depending on where you purchased
it should be no issue replacing.
You should check though to see which is bad. Put
both of the old RAM in to make sure things still work
as before. It is possible something else may be wrong.
If all is well, then swap out with one new module at a
time and see how it works. It may be just one module
(most likely).

Again Ram Upgrade
