I have just switched over from Windows 7 ultimate 32 to Windows 7 ultimate 64. After I swapped over, with the four (4) gb of ddr2800 I was using, the system booted up with the quickness. However, I installed four (4) more gb of the same stuff and the system wouldn't even get to the bois screen. So I took out one of the modules and tried with six (6) gb onboard. The system booted fine. I then put the 4th module back in and was able to get a half-ass boot that ended in bsod. Finally, after being able to get to the bios, I tried to up the NB voltage a hair. No good. Ended up having to reset the CMOS.
After repeating the steps up to the successful entry into the bios with 8gb onboard, I nudged the DRAM voltage+ .30v. Now everything boots up and that but slower. I mean, it went from BOOM!--booted, "welcome to windows!" to "yeah, yeah, I'll be there in a minute!"
So, I'm wondering 1) why would the system do fine on 6gb with no voltage increase on the memory but require a .30v boost for the 4th module? and 2) will my modules survive at 2.08v when they are rated for 1.8v (xms26400)? and, Finally 3) why would I be booting so slow? (I'm thinking maybe the extra modules make the "road" longer, but I wouldn't think it would double the boot time).
Thanks for any feedback
