If you're looking to manually set it, then put the uncore multi at 38x, and the uncore voltage at 1.18-1.20v....

I read up on older gens i7 there was a setting like uncore you set dram x2, I decided since that's over 200mhz stock, i'll apply it. Running 4.2Ghz/3.6Ghz (1.8Ghz dram x2).

The uncore is the same as the cache/ring with haswell. Socket 775 it was northbridge, x58/p55 it was uncore, p67/z77/x79 there is no specific setting for the frequency, it was tied to the processor speed (cpu at 5ghz, uncore was 5Ghz).

With chips like bloomfield (i7 920) the uncore had to be minimum 2x the memory speed, with gulftown (i7 990x) it had to be minimum 1.5x the memory speed. These rules don't apply to all the newer generation cpus though

After reading the first thread a couple of times over, I think I finally found a stable multiplier/voltage settings of 45/1.29 without running too hot.
The next step to 46 brought my temps to 81-85c and the voltage over 1.37v just to be able to run RealBench's Benchmark test. (I'm currently reaching 71c using RealBench)

Now, the next step seem to be upping the uncore and uncore voltage to further increase performance, what are some good numbers to start with for uncore? And how much do you guys usually increase the uncore voltage by while testing stability?

sorry i should have been more clear, i have my 4670k overclocked to 4.4ghz and i want the uncore to be at 38x instead of the original 34x(i know that intel boost is at 38x)

you think if i dont change the voltage and leave it on auto it will most likely start to bsod?

If you leave the voltages on Auto, then there's more of a chance of instability occurring....It's better to manually set the voltages....thumb.gif

Thanks for clearing that up. However I found the sweet spot I guess! anything past 3.6ghz uncore fails x264 benchmark, unless I up the vring. Running 44x core / 36x uncore (newest 64-bit) prime95 running over 3 hours so far!

alright il switch it and see how 1.18v works first.


About x264 where can I get the loop to work ? I have the folder with stress testing but its only once and I don't know where the download is for the loop of x264? (its not in the folder unless its called something else instead of loop.exe??)
post #9559 of 19540
Anyone know what program shows this information? This is the stepping, we all have C0 AFAIK so I'm curious which "version" I have.

B0 (QDE4), early C0 (QE6S), but not good with later C0 (QEH6).

I believe CPU-Z shows that information....
