i7 975
ati 4890 series x2
corsair pc3-10700h ddr3 triple Chanel
and a termeltake 1200w psu


just looking at getting a little more speed out of it

have some knowledge but it keeps crassing

thanks for the help

try baby stepping your oc and run stability tests for each run. If you're stable move up a bit, maybe 100mhz increments. what are your current settings?

Hi thoneon, what wermad ment was to
boot into bios.
find the fsb (it may say cpu frequency)
your stock fsb is 132 (i think)

this is a very basic explanation of overclocking

its basic maths.
your I7 975 has a fsb of 132 and a multiplier of 25, so 25 x 132 = 3.33ghz, your stock speed

unlink your ram, so it stays at stock speeds, you can overclock the ram later

can you raise the fsb? yours is now 132
try rising it to 150
boot into windows
download realtemp and coretemp (google them)
install and run them
then download intel burn test (ibt) and run it.
have a look in task manager and notice how much free ram is listed.

in ibt set threads to 4 (for 4 cores) and then click on custom ram and enter an amount just below the free amount.
eg. i have 2520mb free ram. so i enter 2500 into the custom ram.
run the test for 5 passes. for now, and then at final speed you want, run for 2 hours.
keep an eye on temps (do not let it go over 80.c)

if test runs fine, go back into bios, and change frequency (fsb) to 170 and repeat the tests.
keep doing this in 20mhz steps until windows will not boot. then just go back a step (remove 20 from the fsb) to the last stable frequency,
or
just raise the cpu voltage a couple of levels. it should now boot.
its a balancing act, higher voltages will get you higher fsb, but it will also give you higher temps.
max voltage for your cpu for 24hr use is about 1.4v

the trick is to do this step by step, just take your time

get the cpu maxed before increasing the ram speed
