AM3 System Overclock Advice.

post #1 of 3
Thread Starter 
Hey all... I need some advice. I'm trying to get as much as I can out of my PC, and I can't settle on an overclock 'profile' if you like...

Basically, I have a few options -

Currently, I'm sitting on 220x19 (4180), 2640 NB, 2200 HT, and RAM at 1760 9-9-9-21-27-1T.

These are the NB / CPU figures I want - I can't push the CPU far beyond 4.2, and the NB can reach 2.8 but it needs 1.33V for that - 2.6 takes only 1.275 - and the temps go up quite a bit as a result.

I don't know if I should keep that set up, or -

1) Raise my base clock as high as it'll go and lower the multipliers.

2) Lower my base clock to stock (200) and up the multipliers.

3) The biggest 'concern' I have is my RAM. I just don't know if I should be running it at 1800+ 9-9-9 or ~1333 6-6-6. I know the Phenom II IMC runs at 1333Mhz, but benchmarks (SiSoft) give me better memory bandwidth and latency at 1800+ 9-9-9.

Bah, I just don't know... Any advice would be great. Its an X4 970 system, btw

I would indeed get some MOSFET cooling on that before pushing any further.

However, 2.8GHz at 1.33v is okay for NB, mine took 1.311 just to get 2.5GHz stable, I've get to push on it.
Is 2.8 your max at 1.33v then? Have you tried edging higher on that voltage?

Also, while raising the multi is piss-easy, you get better bandwidth/performance when you raise the FSB, you just need to mix it up to get the best from both IMO.
If 2.8GHz is your max NB, then you need to run some tests and see if the performance is worth that extra voltage.
I personally, prefer a push on the NB as much as possible, if it means sacrificing core clocks by a hundred MHz or two, also I'm pretty sure the NB is good for up to 1.45v, though I'd try not to break into 1.4v without water, personally.

Run your RAM at whatever gives you the best performance, AMD is supposed to prefer tighter timings to higher frequency, have you tried 1600 as tight as possible?
With my FSB raised, my Bandwidth is pretty good (19k+ MB/s), even though I run 1066@1000.
