U know the drill.. google is your best friend... but that 1 fact u gave me that i've not yet came across ... so i'm ignorant about that...
I'm still experimenting with my board.. there are alot of things needed to be explored...
i don't spend most of my time oveclocking like everyone else... do it during free time... i may not so called 'experienced" and "skilled" OCer yet..
but doesnt mean i dont know anything about overclocking....

I'm using asus maximus extreme... please help me, how to oc? dunno how to oc....

lol im using ASUS Rampage II Extreme xD..

hai guys

i'm new user for maximus II formula...hahahaha

how to tweak my E8400 E0 to 4.5ghz?

need help


I hv a P5Q DLX (bios 0803) rma last month n having it now a new unit with new bios 1004. Right now, i cant OC Q9550 with that board. The max i can go is 2.98 with all auto. Once i insert CPU voltage and so on for 3.0ghz, it doesnt run with the fans all running 100%. No matter how much voltage i put (it did be ridiculous if 3.0ghz requires 1.35V)

Do help out if possible. Much appreciated

Just select "manual", turn off all those "EIST, C1E, Thermal throttling, etc" and bump your FSB
For a start, leave all your memory timings and additional BIOS settings to "Auto". You can fine tune those later on. M2F is a very stable and overclockable board.

thank bro...very nice guy there..hahahah

My M2F definately is a good board, have a feeling my E0 Q9550 isn't up to par.
It plays everything nicely at 3.4Ghz (8.5 x 400) but craps out on Ghostbusters and Last Remnant. It just reboots randomly. at first I thought it was my
4870x2 heating up, but even at 100% fan speed, it still reboots randomly. Plays all other more intensive games fine though.

I've put it down to 400x8 for now, with vcore @ 1.3v and Cpu PLL at 1.606v (originally was detected as 1.69v! when on Auto).
Passes linpack v2.2 on Standard. Temps are tad high though, reaching 90c on the 5th run (on a Xiggy Red Scorpion with 775 bracket).
Will slowly decrease the vcore and PLL voltage (default should be 1.5v right ?) over the coming few nights.
RAMS are Corsair Dominator 1066Mhz 4GB and 2GB kits for a total of 6GB RAM. vDDR at 2.1v.

Any suggestions ?

Eoma, when you overclock your Q9550 to 3.4ghz, did you test for stability using Orthos/Prime? Which option did you select (SmallFFT or Blend) and how long did you run it? The E0 Q9550 should comfortable hit 4Ghz and I've easily did 3.6-3.7Ghz on my friend's machine.

Prime and Orthos passed the 1 hour mark, on blend I believe (cpu and ram stress right ?) Gotta check to be honest, been a while.
Using Intel burn in to test now since it takes a shorter period. I'm not interested in highest speed, as 3.2Ghz on my quadie and the 4870x2 provide enough power as it is. i just want a mild OC with stability (450x8 would be nice though ) and least heat !, wanna drop the vcore to 1.25 as proc vId is at 1.25v.

Actually Prime or Orthos is the best tool to test (old school way) SmallFFT is good for testing CPU stability so if you can, try running 1.5-2 hours on it. Once you've passed that, start tweaking your RAM (timings, etc) and run Blend just to make sure your memory is working fine. With that, you cover both RAM and CPU.

Only focus on one thing before moving to the other so it's easier to tell which one is the culprit

Hi, new here.
Am using Asus P5WDH (975X) board.

Name Intel Core 2 Extreme QX9650
Code Name Yorkfield
Package Socket 775 LGA
Core Stepping C0
Technology 45 nm
Core Speed 3001.3 MHz
Multiplier x Bus speed 9.0 x 333.5 MHz
Rated Bus speed 1333.9 MHz
Stock frequency 3000 MHz



[attachmentid=1056174]

for quad, i would suggest u use prime to test.
90c for 3.4ghz is too much? my old q9450 C1 full load at 75c only..
dont use auto voltage setting in bios, it will overvolt to a very high value.

Dude.. no point increasing CPU PLL voltage.. just keep it between 1.5~1.52V is sufficient. U should concentrate on adjusting CPU VCC/Vcore and CPU VTT/vFSB...

Yeah, auto = very high voltages. So i'm back at 1.29v for vcore and 1.53v for CPUpll. Things are a lot cooler now. Max linpack reaches 80c highest on core1 @ 3.4Ghz.

The vtt is at default 1.3v, pll at 1.53v.
Any suggestions ?

I've had it run at 450x8.5 = 3.835Ghz before @ vcore 1.35, too hot. Stopped the linkpack halfway.

The ghostbusters problem still happens though (random crashing, even at stock speeds). Maybe it doesn't like x64 or 6GB ram who knows. Any other game plays just fine (3dmark and fur bench too).

As you're not interested in highest speed.... try to maintain your CPU core voltage at 1.25V... and increase the FSB slowly(increase the Northbridge voltage few notches at the same time when necessary)... test with *50 run linpack for each incremental step u've made.... and when you want to stop at certain frequency.. test your CPU with prime95 for *few hours after passing linpack. In your case, its better to run your overclocked processor at default VID. Anyway, its up to you to follow my suggestion... as u can try other ppls approaches/methods that seem work for you...

*Totally up to you.. the longer the better...

As for your reference, here are my overclocked settings. No guarantee it will work for your setup....
Mobo = P5Q deluxe
CPU = Intel Q9550 @ 435FSB X 8.5 =3.7GHz
Mem = GSkill D9GMH DDR2-800 @1045MHz 5-5-5-15 PL8
NB = 1.2V
VCC = 1.2625V
Vmem =2.0V
PLL =1.52V
VTT =1.28V
LLC = enabled
others on Auto
LinPack stable for 3 hours, Prime95 stable for 3 hours for each test(small, blend, large), OCCT test for 1 hour

its not related to vista x64 or RAM size. if it still crashing at stock speed then the problem might due to
- driver problem.. either video or audio driver.. try to update the driver
- game bug... try to patch the game

guys,is crosshair 2 formula good for OC-ing??or there is other nvidia mobo better than that..want to buy new one but didn't know which more good for OC..can anyone recommend me a good nvidia mobo..

what cooling are u using?

Xigmatek Red Scorpion with s775 bolt kit.

please help me guys...wanna oc my E8400 at at 4.3ghz using ASUS Maximus II Formula
