333. Dunno if it will scale with higher multi.

Wow, VERY impressive memory frequency, especially combined with a NB frequency of 3G. What voltages are you using + would it be possible to run a 1M on those settings ... I'm pretty sure you'd be the most efficient on my list

negative, this would be much more efficient.

I'm pretty sure it won't ;-)

seems like my sata corrupted lol...Where is my old pata drive

Phenom II 975 3.3Ghz with ddr3 probly look like this...







@ Massman.. How to calculate pi efficiency? I just run with those "real time and kill explorer" things. I never pay attention on those maxmem and other ostweaks.
Should learn it long time ago
Thanks.

Been a long time bazx

I need to brush off the curse of nforce 680i mobo

I have a question about NB Voltage. So far I haven't touched NB voltage but as soon as I reached around 2100mhz I get unstable during stability testings.

I am now working 265 x 1 = 3710mhz(1.52v) with HT/NB multiplier at x7 (1855mhz) which seems stable so far. I am using the system in sign, and how much can i put on the NB/HT voltage for a 24/7 clock?

[KELL5]

now that's efficient

It's pretty simple, actually: time x frequency = efficiency (lower = better)

You're at 68.5k, not bad, but I had expected a lot better, actually

I can run OCCT for an hour at 3.8ghz but I randomly BSOD in windows with 0 CPU load. Awesome! And setting 1.575v BIOS (previously 1.55) results in 1.475v in windows. Great!

well i hoped to get an overclock lol, cacvc-ac0b50epmw 940 chip, on a dfi dk 790fx-m2rs bios the newest non beta (10/2008),

first thing i need help with is if i add "special vid add" the system gets very unstable. the computer will boot to the bios at a 22x200 just wont go into any windows nor does it at anything above 15.5x200, i have tried upping the bus insted of the multi no luck.

what am i missing? oh the ram im running is 8gb corsair dominator 1066(testing done with 4gb tho), 850w corsair psu. thanks in advance so far my best o/c is 3.1ghz got into windows once at 3.6ghz..

anyone have luck with the 1/16/09 bios? any issues? worth a try?

This is nice!
My chip on AIR will crash @3815/1.45V after 20-30 minutes of OCCT.

I will try 3800MHz then

Build Log, I had it custome modded by a great guy named Mark. http://forums.techpowerup.com/showth...=74303&page=11



Stepping: CACVC AC 0849EPAW I have booted to Vista at just under 4Ghz, and stable at 3.88 as the highest I have gone without extreme volts. This board has a large vdroop and thus I am slightly limited in what I can do without a hardware mod. I run F@H SMP, and GPU 24/7 stable now at 3.81 and I going to start pushing it back up every day untill it wither bombs out witha BSOD, or the F@H SMP clinet freaks. The USB controller doesn't like to be set at "Full speed" in the BIOS, it must be set at "High Speed" or else you get USBOHCI BSOD at the worst times.

Thats quite some introduction, and welcome to the forums

[Dumo]

Welcome to XS Steevo
Nice run there.

Keep pushin with Win7..

[Zeus]

Anyone ever tried 1T on this platform? Don't know if it's even possible.

My new high for SuperPi on AIR



Ambient ~ +6C, vCore is reported correctly and vIMC was 1.32V.

HWBot top AIR for now ...


New personal high for CPU-Z screen (1.638V/AIR)

[gsk3rd]

what cpu cooler do you have?1.63volts on air?

Thats not nice.... , i think i will need to move my stuff again soon. Gratz to top1 super pi1m PII940 on air time!

I have tryed to get higher clocks on 3Dmark2006 and 24/7 and more stability....i have going up about 100mhz more than before(when i did 4260mhz super pi1m) in 3dMark2006 and all my cores can now do super pi1m @ 4.0ghz+ with 1.47v easy with indoor temp 26c and True Black with two slow 12cm fans....waiting for my Ultra Kaze 3000rpm fan to arrive.

What core temp do you have idle @ 4295mhz?

I'm not sure, at 3400MHz it was 24C, haven't checked them @4295MHz
BTW you seems to have better cores than mine
I can do max 4.2GHz on 4 cores, maybe 4.3GHz with cold air
3DMark06 is stable up to 4.07GHz all cores (so far max. tested, could be more), 3DMark 2001 4 cores are good up to 4.15GHz!

PS. You were enjoying top AIR spot for a loong time If you beat me now then my only hope would be new BIOS from Gigabyte with NB vcore or a new CPU

[KELL5]

Is there an AMD Pi toplist? Can't find anything

[Blazer_]

Nice clocks there... what temp did you have on the core?, and what vcore?

HMmh, i don't know
I didn't have HWmonitor so i didn'y know the temps but i was putisde and there was about -5c
Vcore..hmmh..~1.6v, i think..Can't remember

And i just fast tryit max clock, when Asus mobo comes i will do better scores and when i have time, right now i have to study for exams so next Saturday i think i will do some tests with Asus
