Well, I finaly figured things out.
It look like the Vboost is in fact what is causing the vcore of my CPU to go up when it is under load. However I set the vcoret to 1.42v in the BIOS and once in windows running prime95\\under load the Vboost makes the vcore go up to 1.55v / 1.56v. (which I might tweek lower later on)
I did however find out that my CPU is only stable until I reach 3.8Gz, or a multi of 19x, anything higher, such as 19.5x and it is unstable. EVEN if I push or lower the vcore voltage, it makes no difference. Its almost as if AMD or MSI set the max core multiplier at 19x, anything above is not stable...
Here is the interesting part however, I can OC this system on stock vcore voltage all the way up to 3.8Ghz (I'm assuming was\\is because of Vboost).
Now, I increased the Bus speed from 200Mhz to 205Mhz (3.9Ghs) and ran Prime95 for 45 minutes wihout any errors.
My next step is to push the Bus speed until I hit the next wall.... then I'll obviously have to stop.
I'm assuming by increasing the BUS speed I will need to increaset the NB and CPU-NB voltage higher... can any one comment on the highest\\safest NB and CPU-NB voltage on my board? and if I will need to increase any other voltage regulator in the BIOS for this?
Thanks for every ones help. +1 rep for every one!
Edit: I forgot to ask, should I watch the NB temps in HWMonitor? I'm assuming its called TMPIM0, TMPIM1 and TMPIM2 ???Edited by thestef - 4/26/11 at 4:04pm
