OverClocking AMD PhenomIIX4 970BE

[vikas12]

Hi, Guys need help regarding overclocking my cpu currently i have overclocked it to 3.9ghz by just raising the mulitplier in bios Of my motherboard but whenever i m raising it to 20x or more and after it boot up it doesnt remains stable i mean my aim to overclock is to get my rendering speed faster then average so when im going for 4ghz tht time hitting rendering button gives me blue screen it seem my pc remains unstable so i need guide how can i get more clock speed


AMD PhenomIIX4 970 BE 3.5GHZ[3.9GHZ*]
Gigabyte 990FXA-UD5 Motherboard
CoolerMaster Hyper 212+
ATI Fire Pro V4800 1GB GDDR5
500GB Seagate HardDrive
Antec 300 PC Case
16GB Corsair XMS DDR3 1600MHZ 1.65V
Generic 400 Watts PSU

Maybe your Generic PSU would explode ...

What is your vcore voltage ??

EDIT :- Here is your Guide : http://www.tomshardware.com/forum/274820-29-black-edition-overclock-raising-multiplier-guide

 

[vikas12]

1.39v

 

[hasnain11]

Increase the voltage by 1 notch then try .

Have you done stability test with Prime 95 ?

 

[vikas12]

how do i make it stable in 4ghz in bios there are nb voltage and cpu pll voltage so confusion which one to go for increasing cpu core voltage

 

[vikas12]

well for stability i directly started my 3d scene rendering which is so far stable since its using ram and cpu too
only problem is not able to figure out in bios setting which is the exact voltage for cpu and they are all like+0.125v,0.145v etc
any idea in my mobo bios setting which is exact voltage control for cpu?

 

[hasnain11]

See it should look like this : http://www.ninjalane.com/images/ga-990fxa-ud5/9116.jpg

EDIT : Dude is your voltage setting on auto ?? Make it manual .

 

[vikas12]

 

[hasnain11]

Overclock from boot menu Bios it would be easier and at normal your vcore voltage is 1.39v right ??

 

[vikas12]

how to increased the voltage its all +0.025v,+0.050v,+0.100v etc

 

[hasnain11]

Yes use the +0.025 and see it is stable or not .

Dont over volt your CPU , if you do it'll fry .

 

[vikas12]

ok ll do it and check its stability

 

[hasnain11]

Good luck mate

Run Prime 95 for stability it would be better and Don't go beyond 1.45v .

 

[vikas12]

nop dude it isnt working it seem not able to go beyond 3.9ghz in 3.9ghz my vcore is1.39v and as soon as im increasing vcore by +0.025v for 4ghz in first test of prime 95 it shows blue screen

but its stable in 3.9ghz having vcore 1.39v

Did you read the whole guide ??

Are your Ram timings manually set ???

From the Guide :-

First, You need to manually set your memory speed, and CAS timings, and the required memory slot voltage, to your memory manufacturers exact requirements, and regarding the 1T, 2T, setting, for AMD in my experience the 2T setting is more stable, (I suggest 2T to attain your overclock then after you're sure its stable you can set it to 1T and see if your memory will stay stable at that setting). If you leave these settings on Auto the motherboard may fluctuate these settings at the wrong time causing a crash

 

[vikas12]

ok my memory voltage was only in manual but speed was auto ill do it in manual and check it thx for the info

 

[hasnain11]

No Problem

EDIT: Disable all the power saving options like Cool & Quiet .
