New 2gig Ram Module

Hi,
Does anybody know if I am able to purchase a new c2d macbook pro 17" with one 2gig module insted of two 1gig modules?
I would like to upgrade to 3gig but cannot aford it right now and would like the free slot for the future.
Is this config available in the UK?

It isn't a "must" in the previous MBP to have the same amount of memory in each slot.
I believe the requirement for having the same amount in each slot was only for the MacBook, and was due to the fact that video memory was shared with the system's RAM.
I have one 1 gig stick and one (stock) 512mb stick in my "previous" MBP.
If anyone has information to compel me to change out the 512 for another 1 gig, please do so. The Apple Store indicated I would have no trouble with this config.
I understood to have matched 1 gig sticks, improvement would be negligible due to the dedicated video memory in the MBP.
MacBook Pro (1.5 Gigs RAM) and Dual 2Ghz G5 (2 Gigs RAM) and too many iPods Mac OS X (10.4.8)

Macbook pro turns off suddenly after the installing of a new 1Gb Ram

Hi everybody, ive just intalled today a new 1Gb RAM module from the apple store and now my macbook pro is 2Gb.
The thing is that today it have just turn off suddenly, loosing all my work, two times. It never happened before so i think that its just because of the RAM but, can this normally happens? Wat do you think i should do?
Thank u very much!

Sounds like you didn't install the RAM properly. Open back up, take the RAM out, carefully reseat it until you're sure it is all the way in, then put your computer back together and see if that solves the problem.

Mixing RAM Modules (1gig + 2gig = 3gig)

Hello,
I am about to buy a Mac Mini and I am on a tight budget. The one thing I want to do for sure is upgrade the memory, but I'm in a quandary of sorts given my budget. The retailer where I want to buy the Mini from only sells the appropriate RAM for the Mini in 2gig modules. So here's my question: I know it is possible to mix the stock 1gig stick with a 2gig stick to get 3 gig of RAM total, but will it be worth it to me? I realize that the best configuration would be to slap in 2 2gig modules in and just be done with it, but with 3gig, would I be appreciatively shooting myself in the foot and killing the machine's performance, or wouldn't I notice? I need to have the memory installed at purchase because I am physically handicapped and adding the memory myself is out of the question. And after researching how to replace memory on the Mini, I wouldn't have the courage to ask anybody I know to attempt to do it after buying it. Is mixing RAM modules a good idea?
Thanks in advance.
Malcolm

Nope, I am not confused, There does have generation between Mac mini model. Maybe not official, but we all know. Check About This Mac ---> More Info ---> Model Identifier : Macmini2,1 (That means, 2nd generation)
Macmini 3,x (means 3rd generation I supposed)
And the 3rd generation doesn't support Dual Channel, referred to Crucial.com

PowerMac G4 having problems with new RAM modules!

dear all,
I’ve recently got 2 512 MB Ram module from a British eBay dealer, to be used on 2 different but very similar PowerMac G4 AGP Graphichs 400 MHz machines.
I installed the first module in my father’s Mac, and it works fine, no problems of any sort. Then, a few days later, I installed the other module in my PowerMac, and immediately it started behaving very erratically: some programs didn’t open at all and others crashed with no warning, I tried to run Rember but it soon get stuck. I assumed the Ram module was faulty, emailed the dealer (who’s been very helpful) and then sent it back to get a replacement. The new module arrived yesterday, I installed it... and it was even worse: as some programs didn’t open as soon as the new module was installed, I rebooted the PowerMac but it hasn’t been able even to load the OS anymore, it just stopped at the blue screen forever, once came out a black screen and a Darwin login, but nothing else. As soon as I removed the Ram module the PowerMac started to work perfectly again.I'd assume again there's something wrong in the Ram module, but isn't it too much unlucky to get 2 faulty modules one after the other, or maybe the problem could somewhere else, in my PowerMac?!?
Unfortunately I can't test the new module in my father's machine, as we live 700 kms apart.
My hardware details are:
Power Mac G4
Model: PowerMac3,3
CPU: PowerPC G4 (2.9)
1 CPU
CPU Speed: 400 MHz
L2 Cache (per CPU): 1 MB
Memory: 896 MB
Bus speed: 100 MHz
Boot ROM Version: 4.2.8f1
thanks!

ok, I've now tried every possible combination... but with no success
First, taking out one of the "old" 128 MB I realized it was one of the High density DIMMs (chips on one side only) Japamac was mentioning, in total 2 of the 128 modules were like this. However, taking out one or both of them, or even having only the "new" 512 MB module in, hasn't changed much, sometimes the OS booted, sometimes not but there were always some programs not opening/crashing and Rember got stuck with an error message. With just the "new" module the booting stopped at the blue screen (only blue, no apple splash screen in the centre).
With the new module plus one of the old 128 MB modules (the one with chips on both sides) Rember got stuck very soon, and the error message was:

I have had a new ram module fitted and now i have no photos in I photo but they are there on the hard drive how do I get them into i photo as they were.

I have a 2008 Macbook and have had a new ram module fitted and now i have no photos in I photo but they are there on the hard drive on mackintosh ,photos how do I get them into i photo as they were.
Frustrated
Thanks Andrew

changing the ram has nothing to do with the photos missing. Did you install the ram or someone else?

Ram Modules

An excellent ram module for the 865PE motherboards is the PC3500 level 1 modules. They allow for more headroom concerning overclocking and are designed to run at 2-3-3-6 which is the suggestion for this chipset anyway. Why pay more money for the very low latency when it seems to cause many problems with the 865PE and 875 Intel chipsets. Even the Corsair senior moderators recommend the PC3500 over the PC3200LL. I am presently using Mushkin PC3500 level 1 and it seems to work very well and is quite stable. I am very impressed with the MSI motherboards it seems to be the Intel chipsets that are wound a little to tight.

I think that Rastakirk's point is that the 875 chipset works better with more relaxed timings. Corsair even had to reprogram their low latency modules(ras to cas at 3 instead of 2)to function with this chipset. PeteJ61 methodology is correct for his system set-up-but I still wonder. Obviously until the 875 low latency at the fsb level for a non overclocker is the way to go. Congrats to Pet3J61 for being able to achieve this. Yet there are way too many inconsistencies with users concerning the low latency modules. It unfortunately seems more hit or miss as to what will work with what. Bios versions, matched sets of ram modules, maunufactures of the autual chips on the ram, perhaps even the specific board you actually receive are all "X" factors. Never have I seen this type of problem before and it certainly has both the motherboard(in the form of bios updates)and ram makers scrambling. The 875/865 has brought a new level to tweaking and finding compatible peripherals.

How to find the number of Ram modules in M4000 and M3000

Dears,
Hope you all are in best of your health, I would like to know the command to check the number of RAM modules in M4000 or M3000 Sun Sparc Servers. I think it should be via XSCF Console if am correct? I trigger following command *"showhardconf"* got below output.

With the above output I understand that we have the following:-
-> *16GB RAM*
-> We have memory boards **MEMB#0** and **MEMB#1**
-> We have 4 modules on **MEMB#0** and they are following:-
MEM#0A -2GB - if we Upggrade to 4GB what will happen to the existing 2GB RAM?
MEM#1A -2GB- if we Upggrade to 4GB what will happen to the existing 2GB RAM?
MEM#2A -2GB- if we Upggrade to 4GB what will happen to the existing 2GB RAM?
MEM#3A -2GB- if we Upggrade to 4GB what will happen to the existing 2GB RAM?
-> We have 4 modules on **MEMB#1** and they are following:-
MEM#0A -2GB- if we Upggrade to 4GB what will happen to the existing 2GB RAM?
MEM#1A -2GB- if we Upggrade to 4GB what will happen to the existing 2GB RAM?
MEM#2A -2GB - if we Upggrade to 4GB what will happen to the existing 2GB RAM?
MEM#3A -2GB- if we Upggrade to 4GB what will happen to the existing 2GB RAM?
So, I understand that the above server will have 32 GB Ram as our company ordered recently, Correct?
In the specifications of M4000 i see that for these servers we can upgrade he Ram upto 128 GB.
Please guide, any help offerred is appreciated.

A Key document is:
http://docs.oracle.com/cd/E19855-01/819-2210-14/819-2210-14.pdf
The m4000 can have 4 memory modules.
Each memory module can contain up to 8 dimms. (Two groups on same size (A and B) of 4 dimms). Group A dimms may must not be smaller than Group B dimms. (within a memory module).
The server can contain 4 memory modules of 8 dimms ... 128GB is attained by 32 4GB dimms. ( 8GB dimms used to be purchasable but are now discontinued ).
Depending on what you purchased to achieve 32GB on your server then following options are available:
- If you purchased 2 memory modules of 8GB each simply put these in two unused module slots and goto 32GB
- If you purchased 2 memory modules of 16GB each simply put these in two unused module slots and goto 48GB
- If you purchased 4 memory modules of 8GB each using 8 x 1GB dimms then move your existing simms into the group A slots of the new memory modules, goto 40GB and sell the spare dimmms on ebay or put them certain DELL's (then watch the thing crash due to a static dimm destruction issue and possilbe issues as it isn't supported.)
- If you purchased 8 2GB dimms stick them in your existing memory modules
- If you purchased 16 2GB Dimms ... and don have spare empty memory modules sell spares on ebay.
.... There may be further options ....
In general the person you are purchasing from should be giving good advice ... better than mine above.
... My cynical opinion is a lot of partners (and perhaps even Oracle itself) supplying the purchase may be on commission and have no interest and little care in minimising your cost .... having seen the performance of some oracle 'partners' in the uk I can see why some customers might want to move away from oracle hardware.
Please be aware certain games with switching things about could affect your warrantee ... ( its highly embarrassing when a failing disk in a dilbert has the wrong part number or even worse an incorrect backplate affecting the airflow ... ) ... and what you are really paying for is for an engineer to come and sort your server out if there is a hardware issue. So take some of the suggestions above with a pinch of salt.
Please be aware while have I tried to be accurate above I may have made a mistake. ... .... (in fact knowing me I probably have).
Edited by: bigdelboy on 26-Jan-2013 03:51 (NB: adding memory to servers is often a difficult balancing act and may not be cost effective .... and may make smaller dimms redundant in an upgrade in order to maintain supportable/workable configurations). A new T4/T5 may be more cost effective}. Buying fully populated at the beginning is also often more cost effective .... though the largest dimms to achieve highest capacity may be cost prohibitive.

648 Max - Identifying but not using both RAM modules

Hi!
I'm totally new here, just stumbled across this forum while googling for a solution to my problem, so please excuse my lack of proper terminology if that should occur.
I have the following system (data obtained from Everest 2.20 and own brain):
P4 2,80 GHz, no OC, no HT
2x Crucial PC2700 DDR-DIMM 1024MB 2,5-3-3-7 @ 166 MHz
MSI 648Max (MS-6585)
PowerColor Radeon X1950Pro AGP 256MB GDDR3, no OC
Thermaltake Toughpower 850W Modular
Hitachi Deskstar T7K250 160GB IDE
BIOS (this is my weak spot...) Everest says BIOS type AMI, dated 28/1/2003, no info other than that
WinXP Home SP3 + all updates AFAIK
In general, the system is originally ready-built Fujitsu-Siemens system from 2002 (i think), but heavily modified by me (RAM upgrade, HDD upgrade, several GPU and PS upgrades).
My problem is that the computer only occasionally uses both RAMs (i.e. showing 2,00GB RAM in My Computer's properties). More often than not, however, it only shows 1,00GB RAM. AFAIK this problem is pretty recent, and did not occur when the RAM was new and installed by me. I have tried to systematically testing the two different RAM modules separately in each of the three DIMM slots, and the computer booted and ran Windows desktop at idle without problems in all configurations. I therefore dismissed the possibility of both MB and RAM failure, and reinstalled both modules in DIMM 1 & 2, where they have always been located. The computer ran with 2,00GB of RAM for a day, then reverted back to only 1,00GB the next morning. Tried moving the RAM in DIMM 2 to DIMM 3, and the computer ran another day on 2,00GB. However, this morning it was back to 1,00GB again.
Through all this, Everest 2.20 has always detected both RAMs in the correct slots, but have displayed 1024 and 2048MB memory on the System Summary page. Rebooting the computer without dismantling it and fiddling with the modules does apparently not change the usable amount of RAM back to 2,00GB when stuck at 1,00GB.
Anybody know what the issue might be (since none of the components seem to be faulty by themselves) and how to solve it? Please keep in mind that my BIOS skills are shoddy at best (but successfully flashed the BIOS once by help of an official guide, no stability issues after the upgrade), so detailed instructions regarding that might be a bit over my head. The same goes for overclocking or manually adjusting any voltages or freqs, which I've never tried.
Thanks in advance!
EDIT: Apparently a total power-off reboot (power down, PS power switch off, push and hold power button till lights go out, switch back on, power up) seems to reset the RAM to the correct amount of 2GB. Any clues?

The voltage to the memory might need to be raised one notch. That adjustment is done in the bios.
You can download the motherboard manual from this link. http://global.msi.com.tw/index.php?func=downloadfile&dno=3576&type=manual
Section 3 page 27 thru 28 cover the adjustment of the memory voltage.
This is for a retail motherboard. I do not know if your motherboard has this in its bios. It is in a section under Frequency/Voltage Control

Warranty with RAM-modul from third-party manufactor

Hello,
does anybody know if there exists an declaration of Toshiba that the use of third-party ram-modules does not affect the warranty for the computer?
Thanks a lot for your answers!
Greetings from Germany

As far as I know such document doesnt exist. Fact is that you can upgrade RAM alone without service and this will not affect valid warranty. Toshiba offered list of compatible and tested RAM modules and if you use them they will be recognized properly and everything will be OK.
Of course, nobody force you to use these modules. On the free market you can buy what you want. It can just happen that you will buy some cheap, no-name modules and they will not work properly.
So, buy what do you want. For RAM upgrade check Users manuals where you can find exact step-by-step explanation how to put new modules into RAM slots.

K8N Neo 4 & 3 RAM Modules?

Hi
I know this question will probably have been asked a few times, but having searched through the forums and the related FAQs i still dont really know an answer or solution, as im abit of a n00b and dont really understand your replies to the similar questions.
So here is my situation, having upgraded to the new board and CPU, i am using the same ddr ram i had on my old gigabyte motherboard, that being 1x512MB stick and 2x256MB stick which are all PC2700 (333mhz)
Once i first set everything up I realised that my memory wasnt at 1GB as i was expecting but instead at 768MB. Having looked through the manual and so forth I came to the solution that you either have to have 2 or 4 sticks of ram on your motherboard for it to register them all correctly. So i decided to try a spare 256 stick which a friend had of mine so that would be 1x512 and 3x256. On boot it still registered at 768MB.
I then tried 2x512 and 1x256, though this registered at 1GB instead of 1.5GB. So now i am thinking that if you use all 4 slots they all have to be the same size for them to register correctly?
Im gettin rather confused by all this, i dont really want to fork out alot more to get all my ram to work correctly, but am considering buying another 512 stick so I can a 1GB of ram to work correctly.
Please could someone explain the combinations a little better as I didnt really understand the manual, when it mentions the combination between single and dual channel of SSSS or DDDD, i thought it meant you could put whatever size ram modules in but you would only get single channel, whereas if you wanted dual channel they would all have to be the same size?
I probably havent given another information to get a suitable solution back, if you can help me out and need any extra information from me I will be willing to post up, just ask what you need.
Thanks in advance.
Mark

Quote from: Supershanks on 03-April-05, 20:19:08
To get the best out your system I would suggest you get 2x512 Pc3200, rather than the underspecced memory you have. If on a budget some of the value ram will still give you better performance.
see What is the best value ram? For some ideas.
In the meantime you should get best performance from using the 2x256mb modules. This will run in dual channel mode giving about 5% better performnace than running the single 512mb module.
Re fan try disabling cool'n'quiet in bios, you'll then be able to work out if that is the reason. You can always turn it back on if you want.
luck
Hi
thanks for your reply, ive had a little look around, would something like this be pretty good Corsair Value Memory 1GB
So im guessing the 512 stick I have is not as good performance due to its timings or something, 2.5-3-3-7 whereas the 256 stick is 2.5-4-4-8. Does this mean the 256 stick is better? I know that the 512 stick is a viking brand, I dont really know anything about memory timings or overclocking so I dont really know what these numbers represent in terms of comparing memory.
If I were to buy the memory mentioned in the link would I still be able to use the 2x256 sticks to make it 1.5GB, if those 2x256 have identical timings? Though of course this would cause the 512 sticks to run at 333mhz instead of 400mhz.

3 beeps with new ddr400 RAM in KT6 mobo

I've just bought 2 identical Elixir RAM modules:
M2U51264DS8HC3G-5T 512MB DDR-400MHz-CL3 PC3200U-30330
to upgrade my PC memory from 512MB DDR333 to 1GB DDR400...

After removing the old RAM and installing only one or both the new RAM modules, in any combination of
the RAM slots, the PC doesn't boot, but 3 short beeps are heard, which indicate a RAM error.
According to the "DDR400 Memory Modules Qualified Vender List" in this site, this kind of RAM module
is OK for KT6Delta mobo, and I exclude that both the modules are damaged.
Re-installing the old DDR333 PC2700 RAM the PC boots and works as usual....
What can I do? Is there any incompatibility or should I change anything in the BIOS settings?
Thanx!

Try clearing CMOS. Start with only 1 memory. How much max. AMPS. does PSU give to 3,3 5 and 12v. rails ?

Z77A-GD65 no longer boots with 4 RAM modules

I had 4 x 8GB Cosair Vengeance LP that used to work fine, but no longer boots into Windows with 4 but only with 2 RAM modules. Any help in solving the issue would be appreciated. ( I need 32 GB as I run many virtual machines )
The 4 modules worked fine for few months until couple weeks ago, when I saw issues with booting into Windows 7. The workaround was to "warm up" by leaving the PC in BIOS for about 5 minutes and it would boot fine. Since couple days ago, it would POST but not boot into Windows or into live Linux on USB, so I started troubleshooting with bare bones first ( MB, CPU, 1 RAM, PS ) and then starting adding more and more components until I found that 1 and 2 RAM modules worked in either black or blue rail but with 4 RAM modules, it will POST, but not boot at all into either USB based live system or into Windows 7.
Memtest with 2 separate sets of modules pass with flying colors. Mixing the sets work fine too, but add 2nd set (i.e. 4 modules) and it fails to boot. I am leaning more toward believing the issue is with the MB than with the RAM since mixing them doesn't throw any memory error.
Any suggestion on how to check if it's the RAM or MB ?

What voltage is the RAM running? A slight bump up in voltage might help.
As to voltage, I started with standard 1.5 and then incrementally upped it to 1.65v. At 1.6v and above, it does boot into Windows, but intermittently goes into BSOD... Works perfect with 1.5v with 2 RAM modules.
I'll save the money for next build instead of going for 32GB kit. ... guess I'll live with 16GB for now.
Thank you all for the advice.

Can I install an 8Gb Ram Module on a 2010 Imac?

Acording to apple support iMac (Mid 2010): Memory specifications - Apple Support, "You can use RAM module sizes of 2 GB or 4 GB in each slot", but clearly is more cost efficient to be able to install an 8Gb and a 4Gb, as the iMac already comes with two 2Gb modules, the iMac only takes 4 cards and it has a max RAM memory capacity of 16Gb.
Can I install a 8Gb?
Thank you!

Upgrading ram modules on dv4-2145dx

Hello I need a little help about upgrading the ram for dv4-2145dx I need to know two things,first I had tried to unscrew the memory plate or cover but so far the cover just doesn't come off and it just does a clicky sound of sorts even though I had unscrew it and hence I can't access or substitute the ram modules.Second which kind of ddr2 memory module can I use with that laptop can it be 667 or 800 or lower.Well that's all my questions anybody who can help me on this issue I will truly preciate it and thanks for your attention have a great day.

I've used the Kingston brand on all my mac (ibook 700mhz G3,1.25DDR, 1.25 DP DDR & G5 DC. So far no problem. I recently purchased matched pair of 1gig (2 gi)DDR2 533mhz @ micro center, coast me $235.00. I was thinking about getting a seperate module. But I remember reading somewhere that for trouble free, better get the matched modules. 1gig x 2 per package = 2 gig or 512 x 2 = 1gig. I rather use brand for less head ache (so far).

Cannot restart using 4 RAM Modules on 655 Max HT Ready (MS-6730)

When I use four 512MB RAM modules, my computer starts up and works fine. The only problem is, that I can't restart the it (D-LED boot-error: Memory Failure). To make it run again i have to turn it off and unplug the power cable.
When there are only two RAM modules installed (slot 1 & 3), everything works fine.
What settings do I need to make in the BIOS that it works with all 4 memory modules?
I got four identical and tested Kingmax DDR333 Ram 512MB (MPM33d-383, http://www.kingmax.com/product/pro_deskMPMC22D-38KX3.htm)
my pc-configuration:
655 Max-FISR (6730) v1.0
BIOS A6730SMS v 1.1
P4 2.67
Windows 2000 Pro SP3
4 x 512MB Kingmax DDR333 (MPMC22D-383)
MSI Ti4800SE-VTD
Thermaltake 420W; 3,3V/30A; 5V/40A
Ricoh DVD+RW

thanks and cheers

buenas wonkanoby
thanks for your reply. finally i made it work: its this freaky kingmax-ram....
i exchanged two of the kingmax modules by veritech modules and everything works fine now. instead i got problems now with an MSI 648Max-L Board from which i took the veritech memory......
so if anyone else reads this:
[size=15]IF YOU GOT AN MSI 655 MAX OR 648 MAX AND YOU WANNA USE TWO OR MORE MEMORY MODULES GET VERITECH DDR333/512MB (OR WHATEVER) BUT DEFINITELY NOT CRAPPY KINGMAX DDR333/512MB!!! [/SIZE]
cheers and enjoy :D
