Memory upgrade question / mixing dimms

Hi ,
i`m wanting to add another 1gb of ram to my 875P Neo-FIS2R. I currently have 2 x kingston kvr400x64c25/512 512mb ddr400 cl2.5 and want to add
a couple more. I`ve seen slightly cheaper (and in stock) the VR400X64C3A/512 (512MB 400MHz DDR CL3 Non-ECC 3-3-3 DIMM).
question is will this new pair work ok with my existing pair?
thanks in advance
Paul

Here's a link to the Test Report for your board. Scroll down to the memory pic and click on it. Then scroll down to the PC3200 area, that will list approved RAM for your mainboard.

Memory upgrade question

Hey all -
I'd like to increase the memory in my 400 mhz G4 Yikes (PCI). Right now I have one 128MB and 2 256MB cards, both 100.
I've always been led to believe that the max I can install is 4 256MB cards. But I was just reading that I can in fact install up to 4 512MB cards using OSX (I run 10.3.9). Which is true? Is the 1 GB limit based on OS9?
Also, can I install 133 memory? Is that faster than 100? Can I mix 133 and 100?
Can any 133 SDRAM 168 pin work in the MAC, like modules that might also fit in a PC?
I'd like to install at least 1GB to coincide with a software upgrade to Adobe CS2. If I can put more then 1GB that would be great, and the fastest possible.
Thanks in advance.

The following is from the RamJet memory website:
"The original PCI Yikes version was discontinued in the fall of 1999, and all subsequent models can use the AGP version memory. These later AGP models include the G4 Cube, the G4 Sawtooth, and the G4 Dual Processor.
Maximum RAM: Although it is physically possible to install four 512mb DIMMs, this machine will only recognize a maximum of 1.5G under OS9. OX10.0 and later are able to recognize a full 2Gig."

This is confusing - I guess they are referring to subsequent models when talking about the 2GB max and not the PCI.

Enterprise 420R Memory upgrade question...

I wish to upgrade/expand the memory in my 420R from 2Gb to 4Gb. I have a complete set of memory totaling 4Gb from another 420R with boot issues (to be resolved later). I remove all memory fro the ailing 420R, set aside, then remove original 2Gb from 420R and replaced with the 4Gb of memory. When booting the server, it still reports only 2Gb RAM (the "replacement" ram from the ailing 420R was reported correctly on that machine; I removed the memory riser card, still populated, and all MB RAM modules, and installed this into the "original" working 420R). Is there something in NVRAMRC or some other setting that needs attention in order for the system to see all 4Gb? FYI: I performed a "boot -r" after booting to the PROM screen first, but the system seems to "hang" during this, with the following Response:
{0} ok boot -r

...and the cursor just sits there NOT flashing, no useable prompt. System appears to hang here and does not seem inclined to proceed further. Keyboard will not initiate a power-off, nor do any keys seem to work. If I initiate a power-off at the front panel switch, then a Power On from the keyboard, I get the same thing, and the system does NOT boot.
Any Ideas, anyone?? I am not very well versed in SUN hardware, but was "gifted" these systems (plus some drive arrays and a couple of 220Rs). I am sure these systems were fully functional when removed from service. I would like to use them as either Web servers or possibly as "File System" servers, for B/U and archive purposes.

haroldkarl,
just took all memory modules out for an "eyeball" and found the following:
All modules are "Samsung" from Korea.
2ea M344C1683DT3-C60C1 (0111 in upper right corner of label)
8ea M344C1683DT2-C60E0 (0035 in upper right corner of label)
6ea M344C1683DT2-C60E0 (0038 in upper right corner of label)
(this taken from the ONLY small square paper tag on one side of each module, the side without the 2 labels with barcodes)
These modules were installed in another 420R, and it reported 4GB in the "header" of the boot prom screen, while they only show 2GB in this 2nd 420R. Assuming these modules will work with each other, is there a preferred order or "pairing" of these slightly disimilar pieces?
I did check for fully seated modules b4 removing, but did not find any that were obviously not seated well.

MacBook Pro (Mid-2009, 13", 2.26) Memory Upgrade Question

I currently own a MacBook Pro (2.26; 13") (Mid-2009) with 2GB of memory. I purchased a single 4GB memory card that I plan to add in one of the slots. If I understand correctly that would leave me with a total of 5GB of memory (4GB 1GB). Is this workable?
I have heard rumours that both slots must have the same amount of memory. Regardless - will this be detrimental or an improvement?

Running Lion I would say go for more RAM. 2 GBs is Lion's minimum. If you run more than a couple of applications concurrently then you will quickly find yourself low on memory which would slow down the machine a lot more than the lack of matched pair RAM modules. I would say 4 GBs is a good compromise for casual uses. But if you're trying to run all the Adobe CS5 apps or all of the Office apps concurrently, then you'll be happier with 6 GBs of RAM. But it's hard to know what to suggest since only you know your operating situation, so here's some info that may help you make the decision.
About OS X Memory Management and Usage
Reading system memory usage in Activity Monitor
Memory Management in Mac OS X
Performance Guidelines- Memory Management in Mac OS X
A detailed look at memory usage in OS X
Understanding top output in the Terminal
The amount of available RAM for applications is the sum of Free RAM and Inactive RAM. This will change as applications are opened and closed or change from active to inactive status. The Swap figure represents an estimate of the total amount of swap space required for VM if used, but does not necessarily indicate the actual size of the existing swap file. If you are really in need of more RAM that would be indicated by how frequently the system uses VM. If you open the Terminal and run the top command at the prompt you will find information reported on Pageins () and Pageouts (). Pageouts () is the important figure. If the value in the parentheses is 0 (zero) then OS X is not making instantaneous use of VM which means you have adequate physical RAM for the system with the applications you have loaded. If the figure in parentheses is running positive and your hard drive is constantly being used (thrashing) then you need more physical RAM.
Adding RAM only makes it possible to run more programs concurrently. It doesn't speed up the computer nor make games run faster. What it can do is prevent the system from having to use disk-based VM when it runs out of RAM because you are trying to run too many applications concurrently or using applications that are extremely RAM dependent. It will improve the performance of applications that run mostly in RAM or when loading programs.

Satellite A60-199 - memory upgrade questions

I have an Satellite A60-199 and want to increase RAM from 512mb.
Is this possible and if so how much memory can I put in
Mike Hills

The brochure says you can install a 1GB module in the Memory Slot. There is only one slot you can install memory into.
So if there is 256MB onboard, you can increase the total memory to 1.25GB

Quick Question re: Dimm / Memory

Hi,
Yet another question re: Dimm's memory, but I did search before posting.
I have a Mac Pro 3,1 and 6 Dimms
2 x 4 Gig
4 x 1 Gig
Currently Riser 1 has
Slot 1 / 2 = 1 gig / 1 gig
Slot 3 / 4 = 4 gig / 4 gig
Riser 2 has
Slot 1 / 2 = 1 gig / 1 gig
Slot 3 / 4 = Empty
I can't afford 8 more gig yet. When I do, I was going to use the 4 x 4 gig in Slots 1 / 2 on both cards, and transfer the 4 x 1 gigs to slots 3 / 4, as I've read that latency is better on Slot 1 / 2 Riser 1.
However, can I improve the configuration in the memory I use now?
From reading - my guess is that either:
No, leave as is or
(My guess):
Riser 1
Slot 1 / 2 = 4 gig / 4 gig
Slot 3 / 4 = 1 gig / 1 gig
Riser 2
Slot 1 / 2 - empty
Slot 3 / 4 = 1 gig / 1 gig (to balance out Slot 3/4 on Riser 1.
Thoughts?
I'm using this as an editing station with Media Composer 6 on one boot drive, Final Cut Suite 3 on the other.

Can i use Samsung 2GB PC-8500 DDR3 1066MHz SO-DIMM 204 Pin 2.0GB Memory Upgrade Modules M471B5673FH0-CF8 with my mac bool mid 2010?

you are out of luck, I think.
Not using the exact spec for memory wil cause trouble.
When you have the original in (1066MHz) and add another with higher speed (1333) there is a (small) chance that the higher speed one is "clocked down" and will work, but expect kernel panics often. Most of the time it will not work.
If there is no standard spec ram in at all, the mac will not start.
Luckily ram is cheap nowadays. Send it back.
The best way to buy is researching the Manufacturers' site and use the configurator, then go shopping, if you want.
Use only respected brands: Crucial, OWC, personally have not so good experience with some other brands. And remember "pennywise is poundfoulish".
I think Amazon will take it back and refund. Very unlikely that the memory is harmed. Ask them to take it back.

Report on memory upgrade

A couple of months back, I posted several questions regarding memory upgrade for my Mini 1.5 Core solo. I thought I would take a couple of minutes and report on the results.
With memory prices dropping like they have, I decided to take the plunge and upgrade to 2G. Wow! This is now the computer I thought I bought. I run Mail, Firefox, Excel [PPC], Word [PPC] and Quicken [PPC] - plus Norton AV [PPC] - regularly, and Google Earth, iTunes, iPhoto occasionally. Plus an HP printer [PPC driver]. My Page Outs were running 30-40% of Page Ins for my typical use. I waited for program swapping as well as function swapping within a program.
I now wait for virtually nothing! Page Outs are barely above 0%. Programs load faster, though actual processing appears just about the same [as expected].
I purchased Micron memory from Crucial, as I knew it would be "right". It is now selling for $132/2x1G, free shipping, plus tax in many states. In order to insure no problems with validity of my AppleCare Warr, I had it installed by my local [non-Apple] Authorized Service Center for $45. I justified 2G versus 1G by looking at 2x512M costing me about $113 [installed] to double the memory versus 2G costing me about $177 to quadruple the memory.
As I watch Activity Monitor, it is likely that 1G would have accomplished most of the improvement that I see, but I am NOT sorry I went to 2G now when memory is cheap.
Thanks to all who gave me their advice when I first posted.
MacMini 1.5 Intel Core Solo Mac OS X (10.4.8)

I just got the 2 GB Upgrade Kit from Crucial for $120 /w free shipping. Came to about $130 after tax.
I purchased a 1.83 Mac Mini with 512 MB of ram and an 80 GB hard drive 3 months ago. I decided it was the best solution for a recent computer failure. Although quite fast especially for CPU intensive tasks the system would hang on particular tasks.
1) Parallels was virtually unusable (even more so if I had anything else running)
2) iTunes had problems displaying all of my album covers in the jukebox mode
3) Protoshop / Painter slow to load
4) Widgets were slow to load
Having the correct tools for the job, installation of the 2 GB kit was rather simple. I didn’t seat the top SO DIMM correctly the first time around but I was smart to test the system before closing the case.
Improvement was noticed almost immediately.
1) Boot times increased
2) The infrequent Beach Balls disappeared
3) Parallels is not only usable it’s like having a 2nd computer
4) iTunes has no hang ups
5) Photoshop and painter can handle large images with many layers without slowing down. (Large brushes in painter kill the system, but that’s CPU related)
6) Widgets launch faster but not as quick as I would have expected
Over all the upgrade was completely worth it. It is like a whole new computer. Bottom line 512 MB is the bare minimum for OS X 10.4 assuming you do nothing more then Brows the internet, Chat on line or use it as a media device.
I have a hard time justifying the upgrade through Apple’s site. It’s not worth the $120 premium when instillation should be simple for even an above average computer user. Either way I couldn’t recommend any one use a mini with 10.4 with anything less then 1 GB

Update on Memory, plus Question

I have decided to go for 2 x 256mb 400mhz DDR DIMMs, plus 1x 512mb DDR 400mhz.
After reading all of the posts here, I am now more confused than ever.
I'm going to place my order for them on Feb 1st.
What I would like Tiresmoke, or anyone else to do is to answer two questions.
Firstly, will this combo work??
Secondly, where to put the new sticks(ie which Dimms).
Finally, the Bios matter...just how is that done??????
If this matter could be answered as soon as possible, I would be really grateful.

The advise already given Memory Upgrade. seems sound.
Quote
2 x 256mb 400mhz DDR DIMMs, plus 1x 512mb DDR 400mhz
is not a good configuration for your mobo
See Main Memory
Quote
Firstly, will this combo work??
- Doubt it
Quote
Finally, the Bios matter...just how is that done??????
- See manual - Cell Menu P58 or Section 3-23
In the Dram configuration The Memory Timings Auto settings are read from the spd chip on the memory module. These are the manf recomended settings but sometimes need to be set manually:-
1)Like some corsair brands which need different settings to run on the AMD64
2) Where modules with different timings are used.

Programs Quit Since Memory Upgrade

I recently upgraded my iMac G5 1.8GHz memory. I formerly had 1GB and 256MB modules; I removed the 256 and added a second 1GB module (this is the max allowed for this computer). Performance seems improved, but it does seem that some of my programs (iTunes, Real Player, Firefox, Lightroom) periodically quit without warning. Is there any reason my memory upgrade could be the cause of this?
Thanks.

I've heard two things about my memory question. One technical guy has told me you know immediately when you install bad memory, suggesting things would not work as well as they currently do if it was the module. But someone else has said that Lightroom is "adept" at detecting bad memory - I believe indicating that if there's a problem with the module, Lightroom's reaction to it would be an indication it was bad. I'm really not sure which person to believe on this. Any thoughts?
It would be nice if this were true but unfortunately it's not always that easy. Faulty RAM can sometimes cause intermittent problems that are difficult to diagnose. Dennis has a good suggestion in reseating the RAM. Another thing you can try is the AHT again but this time run the Extended test in a Loop overnight as it may not fail the first time you run it. It may take a few runs before an error is detected. Or just flat out remove the newly added RAM and test it with the original dimms.

MS-6195 memory upgrade

Hi,
My system is based on Ms-6195 K7 pro and Athlon 700 mhz. 192 Mb Ram (128Mb module + 64Mb module)
Problem:
when I try to upgrade memory with a sdram 256Mb PC100 module, the memory test can't finish and my system don't boot.
Please can you tell me how configure coreectly the BIOS or tell how to do.

MS-6195 memory upgrade.
I have also tried using new PC100 256Mb memory and am getting nowhere.
The ones that I have bought are single sided, [8 chips on only one side]
and do not work with my motherboard, however, if I put them into another,
older PC, it shows up as 128Mb.
So I assume that the DIMM is working OK, and that the 'old' PC has a memory size limitation??
I have tried the same things as wbs and Grommit and got the same results.
So I assume that the answer is in getting older DIMMs, double sided with 8 chips on either side.
Does this seem to be about right???

Memory upgrade on Satellite A50-104

I NEED TO FIND A 512MB MEMORY UPGRADE FOR MY A50/104 ANYONE NO THE CORRECT ONE TO BUY, I WAS TOLD ON EBAY THAT 512 DDR SODIMM IS THIS RIGHT. ALSO HOW DO I CHECK ON MY LAPTOP FOR THESE DETAILS IF THERE ARE ANY AND ANY OTHER SPEC BATTERY ,HARDDRIVE ETC

Hi
You have several ways to find out what memory module is compatible and supported.
You can use a diagnostic too like Everest, you will check the user manual or the Toshiba website for details or you will contact the service in your country for supported modules.
I will try to answer the question: The Satellite A50 should support PC2700 DDR-RAM like these parts:
PC2700 256MB (PA3311U-1M25)
PC2700 512MB (PA3312U-1M51)
PC2700 1024MB (PA3313U-1M1G)
Now its your choice. You can also google for the offers
By the way: Visit the Toshiba Options & accessories site. There you will find compatible parts

Memory Upgrade on DV7T-3000 (NQ339AV)

Hello,
I have a Pavilion DV7T-3000 with i7-820QM Processor. I am planning on a memory upgrade. Has any one tried upgrading it to 16GB RAM ? (2 x 8GB). As per specs it can only go up to 2x4 GB.
Thank you for for any feed back.

I believe you should try to PM a level 8 or higher expert here and see if they will access someone from HP.

Memory upgrade on the NB550D-11D - 4GB RAM are possible

To anyone who's thinking about a memory upgrade on the NB550D:
The NB550D supports up to 4GB of memory, not only 2GB as mentioned by Toshiba in their specifications.
A memory upgrade to 2GB is _only limited_ by the pre-installed Windows 7 Starter OS, not by the netbook itself.
I'm using Linux Mint 11 Katya, 64bit and my system is running perfectly well with a 4GB ram module. If you want to use full 4 GB ram support, get rid of the Win 7 Starter OS.
The specification for higher volume ram is DDR3 1333MHz PC3-10600 SO-Dimm. I've chosen one 4GB module by Corsair, due to the 30 years warranty Corsair offers.
It took me quite a while to find this out, hope this is going to be a help to everybody who's just as unsecure as I was how to upgrade the NB550D memory. Good luck. ;o)

> A memory upgrade to 2GB is only limited by the pre-installed Windows 7 Starter OS, not by the netbook itself.
I can confirm this. Two days ago Ive installed own Win7 32bit Home Premium and upgraded my NB520 with 4GB RAM. 3GB are in usage now and notebook runs perfectly.
With original Win7 Starter version I have noticed annoying display behaviour while watching action movies. When the scene in the movie was without movement everything was ok but by action scenes some strange lines were shown on the screen.
Now after own OS installation everything works perfectly and Im so happy with my NB520.
I can just recommend it for everyday usage.
By the way: I use 4GB SO-DIMM DDR3-1333Mhz PC3-10600
