QX6700

I have a QX6700 in a Abit AWD9-Max motherboard with 8Gb of OCZ Reaper DDR2 800RAM.

Should I overclock using the FSB or as the multiplier is unlocked use the multiplier?

Or a combination of both and if this is the best option how far should I push the multiplier?

Usually multiplier overclocking is the best - it puts less strain on other components and allows you to run your RAM at its rated frequency.

I was under the impression that using the FSB to overclock yields better performance on Intel Chips (not including sandybridge obviously), rather than the multiplier?

Hmm, why would that be the case?

Thought it was to do with more bandwidth. (Happy to be corrected though :-)

)

However, the OP only has 800Mhz memory so it's better in his circumstance to use the multiplier and probably a 1:1 ratio (FSB:Memory).

if you want to use both, i am sure that you can still get a decent result either way

because when you increase the fsb it speeds up the whole machine by increasing bandwidth and not just the cpu, with unlocked multiplier chips usually a mix of both is best.

but as your motherboard is quite old and only supports ddr2 800 and 1066 fsb chips you may be better using the multiplier unless you get a more modern board.

Use the highest multiplier you can, which will mean using less FSB to get to the desired overclock (should aim for 3 ghz as a starting point). As previously stated, a lower FSB will put less stress on your other components e.g. memory.

Increasing the FSB decreases the drop in performance you get per Mhz as you overclock more, I would see what FSB is stable then take the multiplier from there, that will give the best performance.
