vcore 1.37 = 2 seconds stable
vcore 1.4 or higher = 1 second stable.
The chip does not like voltage. This is why I only need 1.19v for 4.5Ghz!
Any other suggestions to help get to 4.8Ghz?
Thank you everyone
Strange indeed, but maybe there is something else going on. I too have a golden chip and my voltages are very similar to yours yet I can get a pretty stable 5.0GHz and can even run some benchmarks at 5.2GHz. My voltages for comparison are:
Freq. ---- BIOS ---- CPUZ
4.5GHz -- 1.150V -- 1.144V
4.8GHz -- 1.290V -- 1.280V
5.0GHz -- 1.420V -- 1.408V
Where are you measuring your voltage--CPUZ? What test are you running and what kind of failure are you getting? If BSOD, what is the code? Check your frequency with CPUZ under load to make sure you are not throttling. I don't know your motherboard, but you want to make sure disable any over-voltage, or current limiting features. Also disable turbo and speedstep for now until you find out what's going on. Just use two DIMMs for now also at the default settings. PLL, VCCIO, and VCCSA can all be set at the default. Hope this helps.
