I'm having repeated system restarts since going from 4 to 8gb. The crashes occur whenever I push the system to actually use more than 4gb, otherwise it's rock solid and never crashes. The RAM consists of 4x2gb stalks all purchased in one go from Crucial and is listed (by them) as compatible with my specific motherboard. Each stalk works fine on it's own or in tandem, but as soon as I move to all 4 the problems start. Sometimes I see the BSOD with "stop" messages, but most often the system just reboots immeadiatly. Some specs; CPU: Intel quad core q6600 Motherboard: P5N32E-SLI RAM: Crucial. Part #: CT2KIT25664AA1067 ⢠DDR2 PC2-8500 ⢠CL=7 ⢠Unbuffered ⢠NON-ECC ⢠DDR2-1066 ⢠1.8V ⢠256Meg x 64 ⢠GPU: Nvidia 8800gts (640mb version) OS: Vista Home Premium 64-bit SP1 I've trawled the hotfixes here, and on the manufacturers website for each component but haven't had any luck. My drivers, BIOS and Vista updates are all up to date, i've even tried a clean format and install of vista. Can anyone out there help? Fingers crossed, Cameron.
Can you post the error code of the blue screens you get when you install the 8gb of memory. And also try each memory in each slot to see, if the motherboard is causing the issue or not. -- tanuj_chadha
Crash information would be useful. Have you run the memory diagnostic off of the Vista installation DVD? "C.

Some motherboards have a problem when all four DIMM slots are populated. That motherboard appears to be affected. http://www.google.com/search?hl=en&q=P5N32E-SLI+four+sticks&meta= I've found the best remedy is to increase the RAM voltage very slightly and run the RAM at a slower speed. -- Kerry Brown MS-MVP - Windows Desktop Experience: Systems Administration http://www.vistahelp.ca/phpBB2/ http://vistahelpca.blogspot.com/ "C.

I had a similar issue when I moved to 8gb on my system. The ram was producing errors that crashed the system. memtest86 cannot test the full 8gb ram (or at least couldnt back when I tried). I found a program http://hcidesign.com/memtest/ which also happens to be called memtest but runs inside windows rather than at bootup and you can test 8gb of ram with it by opening up multiple instances of the program until you are using all 8gb of ram. I was running 8 copies testing 1gb each and found that I was producing errors. The solution to fixing this problem was as another reply suggested increasing the ram voltage in the bios (only increase it a very small amount) and then try running the memory test again to see if it is stable. I was able to get all 8GB running at 800mhz with only a small bump in the voltage but you may also have to drop the speed of the ram to get it stable. HTH Robert "C.

Sounds like hardware so I would first double check the amount of voltage going to the ram. Make sure it is within the manufacturer's spec. Then, less aggressive timings. Then, try different brand of ram. Then, different motherboard. FYI, I'm running a Gigabyte x48-DQ6 with 8gb of Mushkin Ascent DDR2-1066 with no problems. Hope that helps. -- rumjungle

There is a procedure for this, and as I recall it amounts to doing the Vista setup with 4 megs installed, and then adding the additional memory. I am pretty sure there is a KB article on this. Good luck.

Thanks for all the feedback folks. The problem isn't exactly solved but I have a work around thanks to your efforts. I've bumped the voltage from 1.8v to 1.85v and dropped the speed from 800 to 667, this has fixed the problem immeadiatly. I can't step the voltage by anything less than 0.05v but i'll experiment with small increments of speed till i find an optimum. Thanks again.
