Hi

i have a Biostar B75MU3+ B75 Socket 1155 VGA DVI HDMI 6 Channel Audio mATX Motherboard (can i overclock gpu with this)

and a gtx 570 asus directcu2, and was looking to get some more performance in my games, i have msi afterburner but i have heard you can only overclock this card with smart doctor, i tried installing this and it runs and says cant find graphics card

i have never overclocked before so any suggestions would be a real help

so any advice would be very much appreciated thanks

Have you tried the msi afterburner? It's very easy to use and for me, more reliable..

Try with Afterburner as adimeister suggested. Also try various versions of Smart doctor, try the one included on the CD and try the latest one from the Asus website

also i have never overclocked before any advice as to process...and will it effect my current mobo? thanks

 

[adimeister]

No effect on your mobo. If you OC your gpu thru MSI afterburner, don't touch the voltage. Try to increase the value of your core clock by 10. Then run the stress test. If stable, increase by 10 again. Then when it fails go down 5. Then find stress test again. Make sure it's stable, and keep an eye on your temp. Then increase your memory clock by 20, so on and so forth.

thanks for reply...i heard afterburner has no effect on this card and you need to use sdocter?

 

[berton83]

also do you have any links for stress test, thanks

 

[adimeister]

It's worth a try. I didn't hear it not work on anything.. I'm not familiar with sdoctor.

 

[berton83]

ok ill give it a go...what stress test can i use are there any free ones

 

[adimeister]

When you DL afterburner, you'll also download MSI Kombustor. That one.

hi again just to clarify up my core clock by 10 and my memory clock by 20 then stress test?? or keep testing with core clock and then memory clock, sorry about the q) just new to me and i dont want to mess up how do i know if its stable or not?

i just upt the core clock by 10 and temp went up to 69

 

[berton83]

and why cant i touch the voltage thanks!

 

[adimeister]

Some GPUs have locked voltage control, it's a company's way to protect your GPU so that they don't need to entertain burnt GPUs. Yes, up the core first, then when you reach the limit, then the memory again. Yea, temp would really increase if you OC.
