Trouble overclocking my GPU

[Apristian30]

hmmmm.... so as soon as i bump my card a bit, my monitor(s) start to flicker..... does this mean i cannot overclock my card at all?



i use MSI afterburner stock speeds at 850 core clock and 1200memory clock.


I have a ATI Radeon HD5700 Series by powercooler. I read on the newegg forums, that some guy with the same exact card was able to push his to 960core and
1445 memory.

Can any1 guess why im getting flickering as soon as i bump either my core or memory clock just 1omhz?

Powercolor you meant? And it doesn't mean you cannot overclock at all, just less, try different clock speeds

Overclocking isnt guaranteed but you should get better than that. Normally you set the clock speed and then enter a 3d app to truly verufy the clock speed works...

What PSU? This plays a huge part.

With an ATI card you can go into CCC and overclock a little in there. Click the lock to unlock and then try raising the speed a little there.

I used CCC and i prefer Afterburner... i messed with it for a bit. I used 3dmark and no matter how little or how much i pushed it, it still flickers. It basically flickers as soon as i change it i even tryed adjusting only the core clock to 851 and same results


and yea i meant powercolor lol

Try reinstalling drivers , update BIOS?

I'm pretty sure they both up to date, i think i checked both last week

 

[shrkbay]

have you tried running it @ default clock?

 

[Apristian30]

my GPU? yea its fine at normal, this thread is about why my monitor(s) flicker when i try to oc my card

 

[shrkbay]

check your box inside? maybe there's something wrong with cables going to your motherboard from the GPU

 

[Apristian30]

Inside my case? theres no cables connecting my mobo to the gpu o.0. Just the 6pin connector from my psu and of course my gpu is connected to the pci express slot

 

[shrkbay]

thats what i meant

Can any1 tells me if my gcard should be o/c if my screens starts to flickers as soon as i increase the core speed or memory
