Any load voltage at less than 1.23v and it crashes when folding. Didn't make much of a temp difference, which I didn't expect it would make much of. So, not sure if it's worth the small decrease in load voltage for the much higher idle voltage
(opened RealTemp after 25 minutes of folding)
Yeah in that case it's not worth it, as you say.
I'm curious however, did lower CPU PLL to 1.6 have any effect on temps or stability? I've never tried lower than 1.7v
Do you still use the same PLL voltage at higher OC's also?
I just started getting serious about setting up my OC Profiles for maximum efficiency, first profile is for 4.1Ghz. Haven't tried lowering these voltages on higher OCs yet, but yeah for this one I dropped PLL, VTT, VCCSA, and a few others. In the pic you can see VTT and VCCSA are dropped from I believe 1.2v stock voltage down to 1.05v, and everything is still completely stable. So, they definitely don't help a mild OC. After reading about how these voltages can lead to faster degredation I decided to see how low I can get everything, not just the vcore. So, yeah it may have helped temps a degree or 2, but mostly it just feels good to have these voltages so low on my 24/7 profile. I'll have to see how low I can get them, and then how low on my 4.5Ghz Profile which I'll be working on next.
Edit: Actually, I did end up getting it stable at a load voltage of 1.224v. Gave me a 1-2 degree difference on the cores from 1.25v, and lowered package temp 3 degrees from 48C to 45C. I'm usually folding more often than not when on this 4.1Ghz profile, so I think I'd benefit more from the lower load voltage as opposed to the lower idle voltage. So, yeah, thanks for the suggestion
Also been lowering the others, including PLL that you asked about, and got cores a degree or 2 lower again, and also package temp down from 45C to 44C. I'm still dropping one at a time, since I haven't crashed yet, but here's where they are at the moment-
