That's not always a bad thing, lower VID sometimes equals higher heat.

this one does run really cool though 67c loaded @ 1.44Originally Posted by NoGuru
Your PLL and VTT are off the charts. Set PLL to 1.50 and set VTT manually, about 1.32 just inch your way up. Usually it stays just below vcore.Thanks! so I decided to go ahead and try again - this time I made it a point to back off the memory and only push the CPU.
So far Prime95 table...but definatley appreciate any insight that might tighten things up a bit. Basically, I started with ET6 to 4.05, added PCI=100MHz, upped CPU V1.34, backed off DRAM to standard (2.66D) @ 1200MHz and left everything else auto. I'm not so sure she should be cooking at 72-73 only 10 minutes, but open to suggestionafter reading through much of this it seems the MCH and VTT are where a lot of the sweet spots lie? but I'm not sure what I should look for there.
Thanks for your help!
JorB3's ram is awesome
I'm still working on tunning things up a bit, but I thought I'd share progress and see if anyone could offer additional ideas that might help stabalize.
The system runs great, but still BSOD/Reboot under Prime95 within 10 minutes. Temps have cooled off several degrees C, and I gained an additional 100Pts in Passmark score by boosting my RAM just need to stabalize it under load and things will be great.

First turn off cpu thermal protection, then enable vdrop correction, because to me it looks like its not turned on, since you have 1.325 Vcore set and you are seeing 1.23 at cpuz.
Next set your vtt to 1.2 and then set your cpu ref to 0.785 and the mch ref to 0.800, and then go back and set vtt to desired voltage i.e. 1.30 as you have selected.
Give that a try now
Took sil3nc3's advice and made the necessary adjustments. didn't want to take a chance on lowering my RAM settings just yet - I actually want to get that all the way to 1600MHz at some point.
I'm running Prime as we speak and getting much better results - OH - I regreased by cooler as well (used cheap thermal grease last time, and found my bottle of Zahlman's ceramic) makes a difference for sure.
I'm 5-7 C cooler, OH and I lowered the VCore, with the droop I noticed it was actually running 4GHz loaded using as little as 1.248 CPUZ, even though I had set it to 1.34BIOSv (so I lowered it to 1.275BIOSv with calibration (prevent droop) and its running Strong at 4GHz and 1.248vCPUZ
Thanks all for your help! If anyone can recommend anything else I could try to fine tune it that would be great. I already tried lowering the voltage in small increments - 1.275 seems to be the lowest it will run...what about some of those other values - should I now try adjusting them higher or lower to gauge impact to performance, temps, etc?
Thanks for all the help!

Yeap - the RAM sucks, or I suck, and since I'm not willing to face the reality that it is me, it must be the RAM, I just can't squeeze any more performance out of it...on the other hand, I finally confirmed I'm 24hr Prime stable and incrementally lowerd my Voltages to 1.2875, thermals are much better - never above 69c and generally average 60-64c. (loaded) and idle around 39c
