Hello Gigabyte,
cpu - i7 870
mobo - Gigabyte P55A-UD4 (latest BIO F8)
ram - 4x2GB G Skill F3-17600CL7Q-8GBPIS (DDR3 2200MHz 7-10-10-28)
QPI/VTT set to 1.47v
CPU VCORE set to 1.3375v
DRAM to 1.660v
I have overclocked the i7 870 beyond 4GHz and now is running at 4.05GHz with the RAM at 2208MHz and XMP on. RAM voltage set at 1.66v, BCLK at 184 and Multiplier at x22. Core voltage at 1.36v (MAX. at 100% loaded).
I have been testing this setup in PRIME (with various voltage settings). At 1.36v MAX, core temps are around high 70c and low 80c in average. Every time the system runs pretty well before 1.25 to 1.5 hours and after that fatal error occurs (one or more workers stopped working).
I would like the system to run with trouble free at PRIME at least for 2 hours (if possible, higher CPU speed as well).
So Gigabyte, any good recommendation?
Thanks!
