Post Your Overclock!

Raising the HT Link to 2500 was a last resort. I've been pushing the RAM as far as I can today. Wish this was stable..

If you lower the HT Link and NB Freq, then raise the RAM freq multiplier does that work and maintain your CPU overclock?
As Essenbe told me, overclockong is more art than science.

Honestly..I've tried everything. I'm settling with this...



Not too bad at all

Know how you feel. Oddly those setting are a bit better than your other snip with 7-8-7-21 timings.

Dropping the command rate to 1T helped

Just a quick and dirty IBT run @ 4.6 using +offset 0.020 - max vcore spike I saw was 1.320



Temps are a bit meh, but it is IBT and the ambient is ~28c, so not that unsurprising. And since it's only a 5 IBT run, there's noway I'm calling it stable, but at least it's showing promise.

I noticed it was changed. I changed mine to 1T and I would always have core 0 throttle to x4 and around 1GHz.

On Maximum that'll be more stress than you can put on it in regular use, unlees you run folding@home or do NASA flight calcs.:)

Aside from a 'quick' vcore/temp test, I don't really trust IBT and variants (ie LinX) all that much when it comes to stability. With previous chips I've had them @ 20-50 pass runs that breezed through the tests only to BSOD in certain games/apps etc.

5 runs is equivalent to a single pass of memtest for proper testing, comparatively speaking. (Not definitive )




But it's been 'Skyrim' stable so far, so that's a bonus. It's also a more interesting 'stress test' than P95 :)

Command Rate of 1T is higher/tighter than 2T.

If your having any RAM stability issues change the Command Rate to 2T, it will help.
For high CPU frequencies you may need to underclock the RAM a little, loosen the timings or drop the frequency back to 667MHz.

wishmaster, good job. Congratulations on the new build and good luck with the magical 5.0.

Well I managed 4.8Ghz with it.

I also managed x50 5.0 Ghz. It booted and loaded everything in Windows without issue..
But, it wasn't completely stable though.

Under Intel Burn Test, it would freeze and BSOD on the very first test.
It was probably stable enough to get a CPUz Validation but ... thats cheating IMO if not truly stable.


I was sitting at x50 Multi and 1.4volts, (1.39 in bios) so maybe a vCore of 1.44-1.45 would stabilize it enough to get a few IBT runs in at that speed.

But, Im not sure Im comfortable with that kind of Vcore especially for a 24/7 OC.
That and at 4.8, it was already around 77C, and that was at a 1.36 vCore.

So once it started crapping out at 1.4 vCore I just stopped right there, since that was my personal limit for a bench run.




At least I know its possibly capable of it. From reports Ive seen, most need something around 1.5v for any stability at x50.
Im thinking maybe this CPU would run 5.0 at around 1.44-1.46ish.


~~~ Oh, and these benches were run with all 4 cores/8threads enabled.

I am think without Hyperthrteading it would probably be a bit easier.
