Overclocking i7 965 EE on Gigabyte X58 Extreme

[Badbonji]

I am still trying to find the best stable overclock on this system. Maximum so far is 4.35Ghz under water with 1.37Vcore (loadline calibration on). What is strange is that at 4.15-4.3Ghz the sytem gets stuck when turning off, so I had to get past that and at 4.35Ghz it shuts of fine, using the same voltages from 4.3Ghz. I am very pleased with the board, I haven't had much overclocking experience as of yet. QPI is at 7.7Ghz.
Prime 95- small fft stable 4 hours.

Setup is in sig, and so far the only real trouble was installing raid, which in the end I found out that my external USB drive somehow was conflicting the raid configuration during OS install which was fixed by unplugging it during setup.

Maximum I have posted this CPU at was around 4.8Ghz, failed to finish loading OS however, may work on that further to get some nice benchmarks.

Hi

did you try to use hints from overclocking guide for EX58-Extreme from this location ?

I did take a look at that but found that using a higher multiplier is more successful, and I have alot more freedom with the QPI/uncore and memory speeds. Wheras the 920 is limited to a 20x, with the possibility of 21x/22x with turbo mode.
