I still have much to learn...
I see similar things when benching on LN as well.. few CPU's CB at -120..yet can tolerate up to -140 if the load is "heavy" enough.

ie- 655k could bench 3D @ 6ghz, with CB of ~120c.. but would need to be pulled down to -136 or so right in the middle of the bench for it to finish.. warmer an it would crash..too much colder and it would hardlock->CBB

yea i noticed teh same exact thing when running a load and i think its because of the amount of heat that is actually produced brings the actual core temp up more than we can measure. Plus add the fact that current is running crazy it might actually change a lot of aspects of the CPU.

Anyways yea retail 990x are doing as good as ES ones, i think the thing about the whole ES thing is that ES chips don't have TDP/TDC standards, so an ES chip could pull a lot more current and/or have much higher leakage transistors which is really what makes a good subzero clocker.

with ES CPU the CPU has already been tested/abused/or whatever they do to test them. Usually i think they just toss them into a board and see how they react on air, those that have higher temps usually are the better ocers because of the leakage.

I think you did pretty good for a retail CPU, clocked up pretty nicely, its still crazy with the 980x with those orignial ES still ruling the charts.

I'm happy with this chip, my 980x had a nasty CBB & doing the pulldown every time there was a full shutdown ate up a lot of ln2, even if it didn't clock a bit better & have a better IMC at least the ln2 goes a lot further with this one.

*you try single and dual channel CB & CBB to see if you can get higher?
post #1435 of 7325
I did, makes some difference. Been benching with dual channel a fair bit lately, & did that 6.4ghz validation in single.
I should really start taking notes on where I get the best results for what I'm running, taken pen & paper to the bench station a few times but forget about notes once i get going...

I have been doing the same to try to get farther in benchies that dont need triple chan. or dual... ie- 1mil Pi, PiFast and Wprime's.

*Dual for 3D is 50/50 I'd say.. if you can make up with additional clocks its good for stuff like '01 & '03 .. AM3 and 3d'05, im not so sure..havent tested dual vs triple in those yet.
post #1437 of 7325
01 single is good...
03 likes high bclk, at least i have found on SB.

single for '01 eh... with i7 or newer Id imagine..right? Because i5 sucks in dual channel as it is..so I would fear looking at i5+1chan. score

I always have a sheet of paper for every new component I'm testing. Helps tons when trying to figure out what'll help.

01 single channel on an i7 is worth trying, test your results.
01 single channel on SB is perfect.

03, bclk at 100 i was 68k
03, bclk at 104.2 i was 70k
on a 4870. all settings remained the same. just upped bclk to get improvement.
