Solved More than 2gb ram stops sound working

August 22, 2011 at 14:24:33
Specs: Windows vista 64, 2.3 dual core/
Hello, my computer came with 2x1gb ram. Recently purchased 2x2gb ram which works fine except sound stops working. Retern to 2x 1gb and sound works again. Tried just 1x2gb in 1 slot and sound works. Use 4 or 6 gb ram and sound stops working!

The short answer.

The Elpida ram is unbuffered (not ECC) ram
It has ram timing numbers 7-7-7
.....

The Amicroe ram IS ONLY LISTED FOR MAC COMPUTERS !
There's no way of knowing whether it will work properly in your PC mboard !

Its ECC ram.
That in itself is not a problem, except that all your modules must be ECC modules in order for the ECC features to be supported by the bios / mboard. If you use any of the Elpida modules the ECC features will not be supported.

Ram timing numbers not shown.
Are they shown on the label on the modules ?
....

Ram that is not 100% compatible may work fine when one module is installed by itself, but it may NOT work fine when more than one module is installed that is the same or different !

Test your ram with ram diagnostics when two two Amicroe modules are installed, and when one Amicroe module and one Elpida module is installed.
If it fails the tests, you can't use the Amicroe ram in this mboard !

E.g.
This one is pretty good, but it can't test more than 4gb of ram - Microsoft's
Windows Memory Diagnostic:
http://oca.microsoft.com/en/windiag...
It can be toggled (press T) to do a standard or a more comprehensive set of tests - use the default 6 test one first - if it passes one pass of that, use the latter one. A few of the tests in the latter set are intentionally slower.
If you don't have a floppy drive, see the Quick Start Information at that Microsoft link for how to make a bootable CD of the Windows Memory Diagnostic (you need Windiag.iso - you don't necessarily need to use the program they mention to add it to the CD).

Lenovo ThinkStation S10 (6423, 6483-xxx)

" Use 4 or 6 gb ram and sound stops working!"

Your model doesn't support 4gb modules.

E.g.
Crucial® Memory Advisor results for the Lenovo ThinkStation S10 Workstation.
http://www.crucial.com/store/listpa...

Quote the brand and part numbers of the 2gb modules and the 1gb modules.

Yes that is correct, the machine has 4 slots for ram and it will take up to a total of 8gb (4x2gb).

Amicroe 2GB DDR3 1066Mhz/PC38500 ECC Dimm"

I asked for the manufacturer's module part numbers.

Elpida part numbers begin with EDJ

Amicore part numbers begin with AMI

If the Elpida 1gb modules came with the system, they're probably definately 100% compatible (with using them in your mboard).

The Amicore 2gb modules may NOT be 100% compatible.

OR - they may all be 100% compatible but the bios has chosen incorrect ram timing settings when at least one of the 2gb modules and one other module are installed.
Oddfball things can happen in the opertating system in that case.

The ram modules have ram timing numbers.
They're usually printed on the label on the module, or if not, they are specfied in the specs for the modules
Either they're a string of 3 or 4 numbers - x-x-x-x or x-x-x.

Most if not all bioses assume that the ram modules conform to standard JEDEC standards.

In some cases, the module doesn't conform to standard JEDEC standards and the bios sets at least one of the ram timing settings for it wrong.

When you have a mix of modules with different ram timing numbers, the bios is supposed to automatically use the same timing numbers as the highest number in each position in the string of numbers of all the modules for all the installed modules, but sometimes the bios gets that wrong.

The ram timing numbers can be higher (slower) than that, that doesn't do any harm, but if any are set lower (faster) than that, the ram will NOT work properly in the operating system.

Take a look in your bios Setup.
If the bios has chosen any ram timing number that is LOWER than it is supposed to be, you must custom set that ram timing number higher.

Thanks for your efforts Tubesandwires, this is going a bit over my head.
I have the part numbers
1gb original stick:ELPIDA 1GB 1Rx8 PC3-8500E-7-05-DP
EBJ10EE8BAFA-AE-E 0807AXB0515
on a second sticker is
FRU:43C1705 11S41R0770ZVJ36R81K17B
P/N 41R0770

After searching through the rubbish I found the new 2gb package
Amicroe 2GB DDR3 1066Mhz/PC38500 ECC Dimm
Amicroe Part#AMI2GBSD-8500H

Also if I just put one of the new 2gb sticks into a slot (total of 2gb) the sound works.
anymore that a total of 2gb and sound stops!
