Memory seems to prevent start up.
Hello all, i'm new to the forum and in dire need of your help and advice.
I have recently purchased another 4GB (in two matching pairs of 2048MB) of Corsair TwinX to go with my 2GB (in two matching pairs of 1024MB) in my system. I installed these into my PC whilst it was running Windows XP. The PC worked fine during the brief time I was running it, a matter of days. I then installed Windows 7 Ultimate (32bit) which installed correctly and updated itself accordingly. The trouble started when I tried to enable SLi in the Nvidia Control Panel. I could enable it ok and even play a game but if I then restarted the PC it would hang at the Windows 7 start up screen. The bit where the flag comes together and then it pulses three times before continuing to load, it would pulse three times and then just sit there. Only resetting the computer can get it going again and then the windows recovery screen would come up. Only using this to system restore to a time before enabling SLi would let me start up correctly.
I thought this was a problem with graphics drivers for a long time and spent most of my energies chasing that but then by chance I found that going back to my original RAM fixed the issue. With this in mind I tried each of my new sticks of RAM seperately and again had no problems. It is only when I have both of the two new sticks of RAM in there that I have the issue. This may be because I have over 2GB in there.
A new developement this evening is that after setting a system restore point with SLI already enabled and forcing the error by inserting two sticks of 2048MB in there, if I then take out a stick leaving just 2GB in there and system restoring, I can start up again and still be in SLi.
So it seems to be consistent with having more than 2GB of RAM inserted with SLI enabled. I realise that 32bit Windows is limited to 4GB anyway so 6GB would be overkill but I at least want to be able to run 4GB of RAM with SLI enabled.
My full Spec :-
Intel E8400 3.0Ghz
6 GB Corsair XMS2-8500 (2x2048 and 2x1024)
EVGA 780i SLI Motherboard
Two BFG 8800GT OC2 in SLi
Creative SB X-Fi Fatality
Coolermaster 1KW PSU
WD Raptor 300GB HDD
I've been at this problem for six weeks now and at a dead end. Can anyone help me?
