PLL Voltage and QPI voltage

post #1 of 3
Thread Starter 
So, I did my OC a month or so ago, but didn't touch my PLL voltage as I don't really know what it does, so its running at auto (1.8V I think), is that way too high for 4 ghz or?

Second is QPI voltage, I got this at 1.38v I think, I see someone recommending 1.35v as max and others 1.45v on air. I have a Corsair H70 for cooling.

Thirdly it was something I didn't remember just as I figured I'd write this thread so I'll just ask if 60-65 degrees celsius with a 4 ghz OC are bad temps during prime95 with H70? Hope I remember what that 3rd question was really supposed to be

Chip is a i7 950 and R3E. My RAM shouldn't be limiting me either

Stock is 1.8v.. so no it isn't too high. I believe most people recommend 1.4 max for the QPI Voltage on i7 9x0's.

60-65C is pretty decent, I usually say as long as you're under 85C you are fine.

Your temps are good. Don't ount on lower temps because it's not real water cooling. You should be happy that you have room to overclock Your i7 more, I think 4.2-4.4GHz should be enough As I remember PLL voltages gives You more stable voltages, so recommended is 1.88v. I didn't noticed any temperature incerase after changing that. Also QPi voltage is important also, if it'll too low You can notice random BSODs or freezes. So if everything is OK just stay with Your settings and be happy
