first time OC my E7500 from 2.93GHz to 3.4GHz.

my rig:
Intel E7500
Asus P5QL-PRO
Kingston and Mushkin DDR2 2GBx2
Tagan 700W
Xigmatek LOKI SD963 CPU Cooler.

googling around, I found that this board should at least can do 400 fsb, push more bro
i'm only using cheap G41 mobo, still able to push until 344 fsb (E7400 344*10.5 = 3.6Ghz), vcore@1.4V

haha... that's right. but need to change a great cpu cooler first.. maybe CM812 or noctua b4 go more higher OC and hyperX ram or corsair vengeance. now i use kingston value ram only.. plus need to change to bigger casing also. my casing now is aerocool vs3. not good enough for airflow.haf-X
or CM stryker is better. OC is just not achieve a highest frequency, but u need to think all aspect that maybe can make ur system unstable for a long period..

Value ram is fine
I find they can be OCed to 450mhz or so(DDR 2 900mhz) usually

i'm using stock cooler with 333*10.5 = 3.5Ghz 1.35vcore
and using KVR too. don't worry i just like to keep poisoning people,
wanna bring back the OC scene just like during single core/ dual core/ X2 era

OC old timer..

Can it be done with e7400?

yup with E7400 i can go up to 344*(cpu multi)
err... which board do you referring to...

mine was ASUS P5 G41T-M LX
http://valid.canardpc.com/show_oc.php?id=2549200

I got both E7400 and E8400 but only got this mobo
Asus P5KPL-AM
http://www.asus.com/Motherboards/Intel_Soc...#specifications

E8400 more suit this mobo for oc right?

is it safe to run around 1.4v vcore 24/7 using stock cooler and a coolermaster 460w PSU? using E6750 with asus p5k mobo.

from experience, that board's pretty inconsistent and imo not really suited to heavy oc -the ~340 fsb sounds about right though i'm pretty sure the oc's achievable with less voltage (1.3-1.35 range)

but stock cooler?!

that board was never designed for OC purpose bro...
if you want a good OC mobo (775 socket) try find used P45 chipset. example :
1. ASUS P5Q Deluxe(600 ++ fsb) LINK
or 2. ASUS Maximus LINK (easily reach 600 fsb)

stock cooler as i don't need 3rd party cooler for such voltage + such clock.
btw this OC on this cheap mobo is just for fun

Bro, i got a Asrock G41M-VS3 mobo with DDR3 1333 and E8400,

What FSB shud i set? Currently 333 x 9 and get 2999 only.

G41 was never designed for OC. 333fsb is consider very ok already for that mobo
btw you can try find max fsb for that mobo,
lower the ram divider and cpu multiplier, increase the htt.

333 is stock fsb for C2D E8...

Thanks for the headsup.

How about 400 x 8?

you should try yourself bro.
as i suggested before, try find max HTT@FSB for that mobo.

since that mobo can run 333fsb, you can start from 334fsb onward
increase the HTT step by step.

let say 335-->340-->345-->..............400
i doubt that mobo can reach even 350fsb...

Ok i will try it and post result here, thanks Lengchai86

I have MSI G31TM-P31 motherboard, I can't seem to overclock my Q9550 CPU, I'm stuck at 333 fsb.
Any more than 333 the system won't boot, and will give me an error message "overclocking fail"

But I remembered I manage to overclock my E7500 CPU to 3.5ghz by just adjusting the fsb. Somehow I have trouble with this quad core

The CPU ratio is also stuck at 8.5, I cannot adjust it.
Can anybody help me?

stock fsb for E75 is 266
E7500 @3.5Ghz = 333*10.5

stock fsb for Q9550 is 333, so you need better mobo to go beyond 333 fsb.
try find P45 used

maybe 333 is max fsb for your mobo

All sifu, im using Q6600 and gigabyte g41m-combo..i did my pc overclock from 2.4 to 3.0ghz.. But why my windows gadget show that like unstable..sometimes 1980mhz, sometimes show 3000mhz.. what thats? Kindly advice me >,<
