Thanks for your help. I'll note the exact code when it happens again.

When running a higher Uncore & QPI what voltages would be required to get stability?

at 1.115 you are not going to hit 4ghz The best chips do it at ~1.17.

QPI/Uncore (vtt). QPI has little to no effect on system performance and uncore is a ***** to get stable as far as my efforts have gone.

Ok, I switched to 211x19 to avoid the throttling and the dreaded 20x200 instability.

I got it mostly stable by setting vcore to ~1.19 in the bios. CPUZ would show 1.200 idle and 1.184 under load. That's vdroop, right? I enabled LLC and now it's 1.208 idle and load. Will LLC hurt the chip at 1.208? I've heard that it can cause voltage spikes, but the vcore is still pretty low. (and I bet I can take it lower since it was almost stable at 1.184 load)

Unless you're doing some extreme voltages, you should be fine. I've never read about anyone frying a chip because of LLC. I think you'd hear more about it from intel or mobo manufacturers if it was an actual problem. Besides if you cut your chips life down from 10 to 5 years are you going to care?

As I said, I've owned both. My d0 is much better than my c0. Sorry Thanks for stopping by to troll though.

I don't think it's biased if the statement is backed by empirical evidence. D0's are newer, and have been shown to clock higher with less voltage. I would consider that "better."
