C2D E6420 - Max Overclock

post #1 of 8
Thread Starter 
Hey guys,

im a noob to these forums and have only just started the whole overclocking thing in the last few months.

i got a question i hope is relatively simple, im running an E6420 on a Gigabyte P965-DS3P rev 3.3 motherboard, and OCZ Reaper ram (4x1gb).

my CPU is watercooled and currently i have a very stable overclock of 3.6ghz (450 x 8) @ 1.47vcore (1.44 in windows XP after that whole vdroop thing). what i wanna know is, is it better to have a higher multiplier or a larger FSB? i can also run a stable 500 x 7 = 3.5ghz. im really after peak performance in high demanding games. i've pretty much proven to myself that both methods are stable, 450 x 8 being a bit more stable i admit. the idle temps of each indivdual core are about 27-30 degrees c, at full peak in Orthos they get bout 48-50. system is about 40 degrees at peak load. maybe not even that high cant remember. anyways heat is definitely not an issue for me so far.

which do you think would be the better option? 450 x 8 or 500 x 7? in real world applications. benchmarking/synthetic software doesnt phase me too much, i wanna know if im gonna feel the difference in my gaming.

Cheers.

hello and welcome to OCN

generally, the FSB is the workhorse of any PC. a faster FSB usually means better system performance. however, there are latencies and straps to consider here. since my memory isn't capable of hitting those speeds, i don't know from experience. if it's gaming performance you're after and you can't tell the difference between the two, then i would go with 450 x 8 simply because it will be easier on your motherboard. many will disagree with me.

500FSB is nearly double the standard putting big time stress on northbridge.

you might also have more issues with ram and stuff like that. plus more and more voltage to keep it running.

i'd stay at 450 myself

You won't notice a difference. A slightly higher fsb at the SAME clock speed only gives about 1-3% performance increase, so having the clock speed at 3.5ghz with 500 fsb will def be slower than the 3.6 @ 450 fsb

awesome, well cheers for that fellas.

i currently have it set on 500 x 7, but if its gonna over-stress the motherboard and northbridge with no real gain, then down it goes. im lovin this motherboard, plannin on keepin it for a long while yet.

cheers.
