Ok, I've been running my e4300 (1.8hgz) at 2.88ghz for a while now, and recently discovered that the "memory performance enhance" option was holding my ram back at stock timings, which after changing from [Turbo] to [Normal] managed form 5-5-5-12 to 4-4-4-12 @ 2.0v.

Now I've tried to get some more overclock out of the processor I'm having to run my ram at lower than 800mhz.

[320][9] 2880mhz [320][2.5] 800mhz
[333][9] 2997mhz [333][2.0] 667mhz
[360][9] 3240mhz [360][2.0] 720mhz

All stable in OCCT 3.0 for 20 mins, CPU voltage [Auto] (seems to stop at 1.40) which gets me 1.39 under load and 1.36 idle.

According to reviews my ram (OCZ PC6400 Special Ops Edition 5-5-5-12 @2.1v) isn't a good overclocker, so I'm stuck with 800mhz or lower but with better timings.

What I want to know is... what overclock is going to give me the best overall performance, I'm thinking 3.24ghz and 720mhz.

If you're asking if you're better off with a higher CPU overclock versus a lower one with better RAM timings, the answer is obviously the higher CPU overclock.

Push it as far as it will go, I say, and don't worry if the timings have to be 5-5-5-12 or 4-4-4-12. I run my RAM at 5-5-5-18 @2.0V (same as yours, it's 800MHz 5-5-5-12 @1.9V RAM) to get my overclock. At the same RAM speed, there's not really a world of difference with better timings, synthetic benchmarks not included.

Oh, and pushing 2.5V through your RAM is a bad idea, if that's what the 2.5 was for in one of the options.

Thanks for the reply, i thought that was the case too. My ram is staying at 4-4-4-12 @ 2.0 volt, the [2.5] was the ram multiplier, I think Gigabyte motherboards work differently in that respect, there are 2, 2.5, 2.66, 3, 3.33 and 4.
My ram can't clock past 800mhz and 400fsb doesn't work evn at lower multipliers although I'm sure my board could do ~500fsb. I'm not sure if I can get a higher OC, 80% over stock speed is pretty marvellous anyway.
