intell core duo E7300, new to overclocking

post #1 of 8
Thread Starter 
System:
Asus P5Q SE PLUS motherboard
Intel core 2 duo e7300@2.66Ghz
ZALMAN 9500A CPU cooler
4GB DDR2 ram
GeForce 9800 GTX 512MB
Rosewill 600W power supply

my goal is to squeeze some speed out of my cpu to speed up/smooth out emulation but i have no idea what I'm doing when it comes to this stuff, but its not like i need my hand to be held, just need to know what the limits of what i can do with what i got and maybe a link to some noob friendly reading material biggrin.gif

anyway thanks for any and all assistance.

this is a very basic explanation of overclocking

its basic maths. your E7300 is rated at 1066mhz. you always divide this number by 4 so 1066/4= 266, this is your fsb. (or cpu frequency)
then your processor (cpu) has a multiplier of 10 (it may say cpu clockor ratio)
so 266 x 10 = 2660mhz or 2.66GHz

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

can you raise the fsb?

try rising it to 280
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 2 (for 2 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 50 passes,
(this is debateable, but a stable overclock is usually classed as 50 runs of IBT, but its personal preference)
or try running prime95 for 12 hrs (at final speed)

keep an eye on temps (do not let it go over 70.C) or in realtemp, notice the distance to tjmax, never let it go less than 20

if test runs fine, go back into bios, and change frequency (fsb) to 300 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.
you are fine raising the cpu voltage (vcore) upto 1.36v

with that motherboard you should easily get to around 3.6ghz

i don't think the mobo i can unlink the ram, i've looked over the bios with out any luck and google doens't really have a definitive answer

Try upping Vcore. If that does not work, try to run mem at 700MHz instead of 840MHz

just did 5 passes of IBT at 3.5Ghz ~1.3500Vcore

max temp of 50c so everything looks fine for now,
thanks to the both of you for taking the time to help me out, i appreciate it

well done applaud.gif
but i would run IBT for at least 50 passes to class it as stable.
or an overnight run of prime95 large ftt's test http://www.playtool.com/pages/prime95/prime95.html
