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
Ok I'll try fine tuning the memory, I sometimes need the full 18gb for work though, so I'm reluctant to take it out. I found an interesting correlation with vcore though
My old settings:
4.6GHz - 23x200 1600-9-9-9-27 1.5VCore, 1.66VDram, 1.4VQPI - 28 mins/frame
The settings I've been testing with:
4.27GHz - 32x133 1066-9-9-9-27 1.5VCore, 1.64VDram, 1.35VQPI - 33 mins/frame
4.27GHz - 32x133 1066-9-9-9-27 1.45VCore, 1.64VDram, 1.35VQPI - 30 mins/frame
4.27GHz - 32x133 1066-9-9-9-27 1.4VCore, 1.64VDram, 1.35VQPI - 24 mins/frame
4.27GHz - 32x133 1066-9-9-9-27 1.375VCore, 1.64VDram, 1.35VQPI - 23 mins/frame
@ 1.35V I wasn't stable
Yes I know I've been using high vcores, this chip really isn't the best, temps are mid 50's even with the 1.5 VCore however.
Has anyone seen this before? My expectation was that once you were stable performance shouldn't be affected by vcore as long as temps were in check.
