I'm doing my first bigadv unit (6901) right now and it's taking about 30 mins for 1% on a 4.6GHz 980x, so about 50 hours total. The deadline is 4 days.
A 980X at 4.4Ghz has frame times of 19:50 per frame for around 70,000 PPD. If I was you I would shut down those 2 - 460's because they are costing you 30,000+ PPD on your CPU. At 4.6Ghz you should be getting around 75,000 to 80,000+ PPD with the 980X. You are currently getting around 37,000 PPD with 30:00 min. frame times.

QFT. I had trouble getting my head around the "don't run your gpus" until I saw how much the TPF was increasing with them folding; i7-970@3.850Ghz will do a frame in 23'17", add in 2XGTX260 and the TPF increases to 29'+. So 6'X100 frames=10hrs extra to complete. Not very scientific but it convinced me not to use the GPUs.

I'm not running the gpus because they hurt my ppd so much, so i guess this comes down to why am I so much slower than you? Are there differences between bigadv work units that might explain this?

Update - The other day I tried 23x200 and 21x200 and they were the same time frames on SMP runs, just now I changed from 23x200 to 32*133 and dropped my vcore and memory to 1066 and now I'm at ~24 minute frames. I'm going to try boosting vcore now to see if it's that or the memory or the 200 bclk that it doesn seem to like.

I will give you 1 guess, Here is a little clue my memory is DDR3 2000Mhz running at 1876Ghz 7-7-7-20-72-1T. and on Ubuntu 64 bit I actually get 17:15 time frames for 85,000 PPD, But I am having a hard time keeping Ubuntu stable.

But memory speed isn't sposed to matter for bigadv right?

So I took a small sample of time frames but varying my mult and keeping core frequency constant did little, however varying vcore I found that my frame time went down as I decreased vcore. I wasn't expecting anything to happen except obviously instability at some point. I booted up into windows to see if it affected linx runs and they were pretty constant with vcore. So now I'm just plain confused as to what my problem is.

I'm not the best person to give you an answer but from what others have said I would have thought yes as long as you run 24/7 and don't run gpus.

yeah i have no problem, doing that, what kind of points do u think i wil get?

the reason i wan to go back to 4ghz is cause my cpu sits a very comfartable 54c on the hottest core, all the rest are at 52c, so i guess its just a mental thing i have but i think anything below 55 on i7 of my age is very good and can run for days, am i right?

Yes..!

I'm running at 4.1 GHz now, but was easily able to complete them when I was 'only' at 3.8 GHz - and was even able to get most of the WUs (basically, not the cr@p ones) in on time when I was running at stock clocks, which for me was 2.66 GHz..

Memory speed does matter. Some idiot made a statement that memory speed / timing's does not matter with i7's a long time ago. They tested it on applications that it did not matter on and made a general statement that it did not matter. Well on folding it does make a difference. Unfortunately people choose to believe what they have read and repeated it as if it is fact, rather than test it and determine it for themselves. It has been shown and proven over and over again that memory speeds and timings do make a difference with folding but still people do not know. Any way if I was you I would drop your OC to somewhere between 4.4Ghz and 4.46Ghz drop down to 6Gb of ram get the best speed / timings you can and go from there. I can run mine at 4.6Ghz but I get allot better performance at 4.38Ghz
