Folding on i7-970 24/7, need max vcore

post #1 of 11
Thread Starter 
I noticed this question was raised here in the folding forum for the 2600K and I need similar help for my i7-970 if I'm going to complete a 6904 before the deadline. Currently even with my current OC I'm coming up short.

So if you have experience OCing the i7-970 then I could use your help.

Currently my ASRock X58 Extreme with i7-970 under water is running at 4300 MHz with the multiplier at 25x, the Blck at 172 and vcore at 1.3875v. My folding temps so far are not a concern.

The big question is how high can I push the vcore?

The TC i7-970 in my signature is the rig I need help with.

That overclock should finish 6904 with plenty of time. I was running mine at 4.2-4.3ghz and never had issues with deadlines. As far as vcore goes, if you have a way to cool vrms and the cpu you should be ok below 1.4v. The vrms are the real problem as they get hot and the system gets unstable. I cant remember very well but I keept mine below 80 or it would create BSOD.

Yea that OC should definitely be enough to finish with plenty to spare. Have you downloaded a new WU to see if it still was gonna go over the deadline?

I had two 6904 download back to back and the ETA was past the deadline so I eventually trashed them.
I then ran 10 A3 WUs before trying again and this time I got a 6903.

I've heard that 4.3 GHz should be plenty to run a 6904 but it hasn't worked out that way for me.

I'm running Ubuntu 10.10 using EXT3. What could be holding me back from completing a 6904 on time?

Strange, you should be able to complete them easily. Do you have HT on? Anything running in the background?

You must not be using 100% cpu 24/7 or running other stuff in the backgroung, gaming or something like that. Are you runing tripple channel memory? That will do it too. Your ppd seems low from what I remember. It should be in the 80k+ ppd range for -hugeadv. Maybe someone else running one can tell us.

Also make sure you have things like speed-step and any other power saving features set to 'off.'

Sounds like a memory issue or other things running in the background but you have not provided enough info to figure it out. Please do not be trashing WU's be smart and run -smp until you figure it out. Save a copy of a WU to your desktop and use it for testing. And disconnect from the net when testing. wink.gif

I agree, it def sounds like a mem issue. I remember running my 970 @ 4.4 Ghz and on a 6904 my PPD was about 102k ppd.

This is an excellent idea for testing and trouble shooting without being a detriment to the research. Not bad for an old man. thumb.gif
