Qpi/pll Tags: CPUs DRAM QPI Memory Last response: September 3, 2009 8:43 PM in CPUs Share htoonthura September 3, 2009 5:40:25 PM Hello there, Can you explain me what qpi/pll is and the difference between qpi/pll and qpi/dram. I am guessing the former is for cpu and the second is for memory. is that right? i am giving 1.320 qpi/pll to get oc stable at 3.8? is it too high or safe. What is the safe limit. I am confused with varying results on the internet. Thanks. More about : qpi pll one-shot September 3, 2009 8:43:46 PM I'm doing 1.35V on QPI and 1.88 on PLL for 3.7Ghz. I may try lowering the QPI voltage a little. I tested my system for 22hrs with my settings. That's also with HT/SMT off at 3.7GHz. I use the same settings for 3.6GHz with SMT on.
