if i want to overclock my E6420,
just go to bios n only setting te FSb or other things?
what stuff must be good to oc?
psu?mobo? else?

Select from where? Floppy or USB drive?

ok back to business. Now I think cpu-z is buggy because CoreTemp give me the correct value. See screenshot below

Hi guys and gals,

Trying to OC my Q9450, so far managed a stable 3GHz (350*8) sync with ram (Corsair XMS2 800Mhz)
Voltages:
Vcore 1.15
FSB 1.10
Vdimm 1.9, 4-4-4-12

Tried out on IBT 15 loops.
Screenshot as below:


What u guys think? Any rooms for improvements?

Thanks.

keep going...still got rooms for improvemnt....push higher clock n see how far ur stock vcore can take u

go for 400fsb!

Yeah I'm going for that. Just checking whether I'm on the right track.

Are my temps ok so far? Idle 45 C, Max on IBT 62 C

as for me anything < 80C is acceptable

Its working at stock voltage! Try higher!

Ok i tried 3.2Ghz (400*8) on my Q9450
Voltage settings I got from another OCer in another forum having same proc and mobo as me.

Vcore 1.25
VFSB 1.20
Vdimm 2.1 4-4-4-12
VNB 1.4

Passed IBT 15 loops,

Realtemp shows idle at 45C while max temp during stress is 67C.

Trying to keep the temps lower than 70C, 65 would be just nice, as I read this is the recommendation for 45nm chips.

Gonna try to lower the voltages more.


Comments and advices are welcomed.

What motherboard are you using? I don't think you need 1.4vmch to run 400FSB. 1.3 or less will be sufficient...

@Kuntau

usb mate

Bro!

What is the vid shown on ur coretemp when ur running ur Q9550 at stock speed(2.83G). I can see that your vid is 1.25V at 3.4G.

I think under 1.2v but not sure.. later when reboot time I'll confirm this again, with so much thing on start-up very lazy to reboot LOL

Urs is EO stepping right? Take your time bro! Coz from the stock vid we can expect the overclockabillity of the chip. My vid is 1.1V for stock speed. Cheers!

Using evga 750i FTW mobo. I tried Vnb 1.35, getting BSOD during IBT. 1.4 no BSOD, can pass 15 loops.
Managed to reduced vcore to 1.2375v. Gonna try to go lower.

Yeah E0.. but right now still stuck with stock cooling.. any recommended aftermarket cooling for this chip?

I'm using the xigmatek red scorpion with the crossbow. Quite pleased with it. Anyway, what is your vid at stock speed?

1.1v

Erm.. THERMALRIGHT IFX-14 you think can fit in CM690 casing or not?

Attached thumbnail(s)

just done this...
note that the vcore is 1.525v , i put that high because wanna make it stable... actually 1.475vcore is enough
2.5vdimm to make DDR2 1100 CL4-4-4-4 , PL 9 , trfc 30
vmch +0.1 from default.

I think I couldn't go more after 4.5ghz

Guys, I have a bit of a problem here with OC...
I OCed my rig(as in the sig) to 4Ghz = 500x8 @ 1.375v vcore...on 1:1 though...I've already passed OCCT and Orthos for cpu stressing (8 hours) but when I'm surfing the net with mozilla firefox, it sometimes give out an error...and my utorrent also got error this morning which it never does...

The question is do I need to increase my cpu vtt voltage to make it stable?
