You having temperature problems? Why so concerned about voltage unless you're needing 1.4+ to get there like a few I've seen.

At 1.3V on Very High in IBT, 20C in my room i hit 72C. In the summer it can get to 28C max in my room (small room, facing the south side, no AC) and it will get a bit messy with the temps. Most probably i need around 1.31V for 4GHz

OK guys i want to ask

Is this good for a i7 920 C0
3.9ghz@1.25v 24/7 stable(tested with LinX and crunches 24/7)
4ghz@1.36v stable(tested with LinX 40x)

voltages are a touch high IMO... but its not bad.

IMO i don't think its bad for a C0 but i wasn't sure thats why i asked

thank you for your input

Seem pretty good to me for a C0, however maybe you had a C0 that clocked better, I wouldn't know

Given that each CPU is totally different from the next: if that's what you need for your CPU, then it's good.

I'd say that's in the higher range of C0 chips. Great job making a stable system P o s

Higher as in better? If so I agree. I remember my C0 needed quite a bit voltage for those clocks, but it was a while ago so I don't remember correctly. Damn Binge, I remember the days when we had C0's, it was more challenging :laugh:

I'm sure that somebody would be willing to swap their C0 for one off your D0's if you miss the challenging times :rolleyes:

I still have my small challanges to keep me awake. A slight OC E8400 had run for 60 days 24/7 chruncing with any problems and last night it blue screened. "Old drivers" my a...

A SSD crashed, also last night. Chrunching/folding...might not be good for SSD´s !?

And, well thats it. My darling GB X58 @ 4 GHz and 1.18 V runs nice and cool.

It's ok, I have other challenges to keep me going :laugh:

I have BOINC on my SSD, so far so good.

Messing around with the new cpu

.

FilipM · Apr 11, 2010

I've done some testing on 19x 200, i couldnt get it stable. The final thing that i changed was Channel Data Reference (A,B and C) from auto (0.500V) to 0.485V and i passed 10 times IBT on Very High. Definately worth a go for higher BCLK.

Also, owners of P6T deluxe and deluxe V2 boards, have a look at this:

Athlon2K15 · Apr 14, 2010

can someone give me some insight on what voltages to start lowering first,i set everything using a template from another users that had my board and proc and im just looking to find the lowest possible voltages that it will stay stable at,i have succesfully lowered the cpu from 1.45 to 1.39 and its still stable but need to know what order i should start lowering the rest? thanks :toast:

the only volts i mess with are the vcore qpi and mem rest i set to the default setting

so you dont need any VTT for your setup?

FilipM · Apr 14, 2010

You can try lowering the IOH core and CPU VTT. I don't think there is a need for 1.4 IOH Core, you might get away with 1.2V

You should'nt need any more than this for those clocks...

t_ski · Apr 14, 2010

You might, or you might not. Pick one and start lowering it until it crashes. Then bring it back up. Every CPU/mobo combination is different, even if they are the same models.

Nice, what are the temps like at load on that? I will be getting one in about 10 days to replace my current C0 stepping 920.

One other question for the masses, i read a fair bit i my ealy i7 days about the advantages of using Turbo, is it still a general consensus that (as an example), 4gig at 20x performs slightly worse in most things versus 4gig using the 21x multi..... I only ask this for my 24/7 overclocks, is there a view on which is best, Turbo or non Turbo?

CDdude55 · Apr 25, 2010

These temps to high in game?:

Didn't see your post until now, lol.

Its not as cool as my old 920 C0. I don't know why though but it's alot easier to OC, that's for sure.

Nope, as long as they are under 80ºc I'm good. so that's fine for me. How hot does it get under stress testing?

When i really put it to work(prime 95,etc) it can get as high as 82c.

Older pic of my i7 temps after running prime 95:

Meh, for stressing it that's ok. The 920's run really hot, I've benched at over 90ºc for a while and it's fine. So 82ºc is ok considering it's only while you stress test.
