Here's the situation, hopefully it makes sense...
Current system...
i3 550(stock)
EVGA GT 450(stock)
ASUS P7P55-M
KHX1600C9D3K2/4G 1.7-1.9v
all settings in BIOS are auto except AI overclock tuner is D.O.C.P, DRAM OC profile DDR3 1600(for native 1600 mem, otherwise auto sets to 1333 because of SPD), CPU Ratio 20.0, BCLK 160, all others auto. The CPU ratio and BCLK are set automatically after choosing 1600 profile.
I bought KHX1600C9AD3K2/2 1.65v(?) first but it didn't seem to work(long story). I planned on going to x64 OS later and so went with KHX1600C9D3K2/4G 1.7-1.9v instead. Both bought Oct 2010. Now that I got x64 OS, I decided to buy more of the same memory but can't because Kingston discontinued "C9D3K2/4G" so I asked them which model can replace or go with what I have already. They said these two models can work together and they do...but after ~30min of Skyrim...CTD or BSOD(memory management) or with Batman:AC it freezes at save load. Never any problems before new memory was added.
So, question, can I change VCORE Over Voltage, IMC Voltage, DRAM Voltage, CPU PLL Voltage, or PCH Voltage to make the system stable? Those are the only options I have besides timings which should be the same for both models according to 1600 specs. I thought, since one model is 1.7-1.9v and another is 1.65v I could just bump up the lower one manually to give the others more juice for stability but I keep reading that DDR3 is normally 1.5v and setting DRAM over 1.65v is dangerous?
Lots of reading I know, sorry. I hope I got the point across. Thanks in advance.
