Phenom II steppings and max OC 550-940 - Page 257

post #2561 of 2829
or not, first approach was easy (4343 MHz http://valid.canardpc.com/show_oc.php?id=766654 ), PC dont crash after validation, i was surprised ! With 4365 Mhz i was like for validation , behind next 5s blackccreen and PC restarted

edit: today i have a relax-movies, games etc . But tomorow il try new max superpi 1M (hope under 16.4s)

FlanK3r, we look forward to that. Did we ever ask you what data was listed on the integrated heatspreader (other than the stepping)?

Good luck on the benches tomorrow!

Even on water, cooled with TEC's I can't even get higher than 4140

I think I should start OCing again, LMAO
Yea I hear ya on that one.

Easy..............haha.


Thxs for the info.

others in validation (RAM timngs etc), PSU 500W Seasonic OEM, cooler Coooler Master Hyper 212, chip revison etc is in tabs here, im only broken my records with safe CPU voltage for aircooling(next year maybe with LN2). And in room was 17 C temperature.
Wait, wait, wait. Hold up a second. I just had kinda a duh moment. Does the NB also need to be OC for 4.0ghz+ to be stable? I have totally ignored that fact while OCing this entire time.

Gsk3rd, are you referring to the "NB Frequency"? If so then yes sometimes overclocking that does help with the overclocks. Now if you're referring to just "NB" I'm assuming you're talking about the HT Clock Speed(ie. mobo chipset)? This is typically increased to raise the processor overclock. If you have a unlocked multiplier it's not always required but it is nice if you're trying to get that extra few megahertz

Good luck

CPU-NB voltage is very important to raise when overclocking.

Yea I am actually talking about the NB frequency. I usually never OC my HT link.

But I have some questions for the gurus. I was on air before. I would be able to run 4.0ghz stable enough to surf web, run super pi and general comp things. Now that I am on water what was originally stable or semi stable is no more. My stable clock of 3.885ghz is no longer stable with my WCing setup which doesnt make any sense. Tempertures are a none issue as I put 1.62 volts on the cpu and ran prime for about an half an hour and temps only got to 44c. I know it is not three hours but I wanted to see what temps would get up to.

I have had some issues with my ati driver ever since I hooked up my plasma to it so I am hoping a fresh install on monday will do the trick. If not you will see me posting up quiet a bit. Any thoughts?

Gsk3rd, that is interesting. What Vcore were you running while on air? Did you change anything with your memory? What this previous overclock Prime/Occt stable?

Good luck

With example NB clock (uncore) about 2000 Mhz is more easy get 4000 MHz than with 2600 MHz at uncore or more.
But for practice example (i wrote review about it) is performance x4 CPU at 3200 MHz + 2400 MHz uncore similary as CPU at 3400 MHz with default uncore 2000 MHz.

Uncore clock is second performance level up ---> is better 3600 MHz+2600 MHz uncore than 3800 MHz CPU with default or 2200MHz uncore. 2200 MHz is a some bug, is whorse than default uncore clock.
Second:its very hard got 2800 MHz at uncore stable, i have 3914 MHz+ 2675 MHz uncore stable CPU in x86, performace is generally better than CPU at 4100 MHz CPU.
But u must increase the voltage at CPU-NB for this and this meant too higher temps and whorse stabilty at top clocks. Therefore, for example, for validation is much better to "stick" around the default frequency NB.
For most benchmarks is better higher NB clock. Il posted later today or tomorow a few practical demonstration (cinebench, superpi, winrar).
