Geekbench 64-bit,
[email protected] (BCLK 205, SpeedStep ON), RAM @ 1640MHz
I figured that with a peak speed of 3.84GHz @ BCLK 160, TurboBoost on @ standard Vcore, it won't need too much voltage to run @ 3.84GHz sustained.
So I went for BCLK 205, multiplier 19, to go a tad higher than that; found the system to be stable at a Vcore of about 3.3V (M.I.T. display, don't know the exact number right now and what I set it to be in the M.I.T. settings).
I haven't found a way to get my RAM (G.Skill Eco CL7 1600MHz) to 2050MHz (which should be possible). Tried loosening the timings and increasing DRAM voltage but got freezes during boot. => CMOS reset
Will have to read up a bit on RAM overclocking...
Still, I'm a bit proud of what I achieved. I mean, this is my first non-Apple Mac with my first overclocking attempts.
EDIT: OK, due to the high BCLK, overclocking the RAM is impossible. The G.Skill Ecos can go ~1900MHz but that's not achievable with BCLK 205.
Just for fun and for comparisons's sake, I've added the scores of my Mac Pro, which I'm selling ATM and my MacBook.
