[myxomatosis]

like the discription says I got a BSOD on startup of windows 7.
the problem started about a year ago when I installed a second pair of 1gb memory dimms (total of 4x1gb).
everything was fine and dandy in windows xp x64 but when I tried to install windows 7 x64 I got a BSOD with the statement "ACPI non compliant".
so after a lot of adjusting things I figured out the memory was the problem. so I installed windows with only 3x1GB installed.
last week I decided I needed to update my pc and I thougt the problem was having 4 dimms installed, since 3 dimms worked just fine.
so I bought 4x2gb evo one geil dimms, and installed only three.
result: BSOD on startup(just when the windows loading logo appears). removed another memory unit resulting in 2x2gb and got the same problem.
tried it with only one unit installed= no problems at all!
so I can state the problem is in having 4gb or more installed. before anyone askes, I checked swapping the memory units and the problem is not in the dimms or the slots. windows 7 just doesn't allow me installing 4gb or more of memory.

I checked the problem all over the internet and the problem is around since the release of vista and probably has something to do with the combination between the MOBO and win7.

hope somebody can help me with this problem, running on 3gb off memory when I got a fresh quad channeld 8gb lying around seems like a waste

specs:
am2 3,2GHZ
2x4=8 geil evo one 800mhz 4-4-4-12
1x4=4 corsair XMS2 8000mhz 5-5-5-18
asus M2N32-SLI (supports up to 8gb off memory)
2x geforce 8800gts xxx edition

Welcome to GeesktoGo.

Here, in case you have NOT looked is the memory tested by Asus with that board
http://uk.asus.com/M...ss_Edition/#MSL

As they say, they cannot of course test all memory.
However my experience is, that whenever populating the slots with the Maximum memory allowed, eg in your case the 8GB in the configuration of the 4 sticks of 2Gb and you suffer crashes, and have NOT used the tested ram, the only really effective answer is to speak to Asus and the ram manufacturer, and seek their advice regarding voltages etc manually configured in the BIOS


I find it a little surprising, that on that board Asus list ONLY this ram in the 2Gb
On the DDR2 800 there is only one listing for tested 2Gb sticks
2048MB ELPIDA E1108AB-8E-E(ECC) N/A DS EBE21EE8ABFA-8E-E

and only 2 on the 533Mhz

2048MB INFINEON HYS64T256020HU-3.7-A INFINEON DS HYB18T1G800AF-3.7

I bought the geil evo one because the original 4x1gb memory that also didn't work(only worked with only 3 dimms installed) was noted on the QVL lijst.
namely: 1024MB CORSAIRHeat-Sink PackageN/ADS CM2X1024-6400C4

so I figured, since the board is a bit outdated, and it only had the problems with vista/win7 (win xp x64 works fine withe 4gb/8gb installed) it really doesn't matter, since asus is not giving the support anyway.
so I'm still stuck.
In old threats I found more people with the same problem but never figured out how to solve it, I guess not a lot of people try to max out a 5/6 year old mobo.
so, to be sure I just installed the 4x1gb from the QVL-list to figure out how to get all those working on win7.
any suggestions?

Have you installed all possible driver updates for the board, such as this one
http://www.asus.com/...eluxe/#download

ASUS Update V7.17.17 for Windows XP 32bit/XP 64bit/Vista 32bit/Vista 64bit/7 32bit/7 64bit
under utilities - Asus update for - including 7 64 bit

Also in view of the ACPI non compliant - I would examine if you have the latest BIOS, albeit a BIOS flash is always risky.
Ausu boards have the EZ flash utility

sorry for that,
thing is, I figured the problem was in my bios version but when I flashed the bios my floppydrive gave up on me.
so I got a dead mobo, today installed my new M3N72-D mobo and the 8gig ram seem to be working perfectly,

thx for all your help
