Hi all, I had 1 GB RAM (Dual Channel 2 x 512 MB) GEIL, 4-4-4-12, 800 MHz on Gigabyte DS4 with Vista Ultimate x64 and everything was fine. Then I bought another kit 2 GB RAM (Dual Channel 2 x 1 GB) GEIL, 4-4-4-12, 800 MHz. After start into Vista it works like charm, but only for cca. 2 mins. Then it reboots. I tried WinXP x64 with no problem, Linux as well. Pls help, thx.

do u see any error or any blue screen?

[dieselCZ]

Nothing. Just screen gets black and reboot. I think it is not HW problem, because it runs well in WinXP and Linux.

Pls, knows anyone?

lost most control of my fingers so pleaqe bear with me, it hurts like hell 2 type.

u turn on memory remap on in the bios? with 1 gig it wont make a diff (maybe not even with 2 gigs) since 2 gigs is inside the 32 bit boundary but once u get over 2 gigs of ram remapping memory under 64 bit makes a diff..

As a quickie leave your system exactally the way it is and pull out 1 gig of ram. if the rebooting stops u know its memory remapping. At least the way i'd think.. / thunk...

i'm running 4 gigs ram but if i dont turn on mem mapping i cant even install vista 64bit (quad booting xp, vista 32 vista 64 & linux..
if i leave memory remapping on when i'm in 32 bit winbloze (xp or vista) system i slooowww.
if i don't turn on memory remapping in 64 bit mode system is very unstable & can't install vista 64 bit
64bit mode (memory remapping on) ram shows 4096 megs
in 32 bit mode (mem remapping off) ram shows 2943 megs(dep on no of devices loaded)

Thanx very much .) yes, when i tried run system with only 2 GB RAM and it works without problem. I have to search in BIOS memory remapping. I hope Gigabyte DS4 supports this feature.

have you tried the memory tester in Vista? You may not be getting the problem in xp and other Os's because they use a lot less memory, maybe there is a bad area of memory that you don't see until you start up vista.

[dieselCZ]

I tried the memory tester and memtest from linux boot menu. No errors.

And Im afraid, that there is no option like memory mapping in BIOS on Gigabyte 965P-DS4.

I discovered, that Vista run fine in safe mode, so it could be driver or something.. pls, help

[stevecn70]

I still think something is wrong with the new memory sticks since it worked fine before. Try taking out the new ones and the old ones and put the new ones in the old ones slots and start it up and see what happens. Since you said it ran fine on 2GB, Try running 2GB with the new memory sticks and still see if it runs fine.

[dieselCZ]

Yes, i now run Vista with those new 2 GB memory sticks and no crash.

Could be reinstall help?
