Graphic Card Overclock List and Discussion

[Mr. Officer]

TG...thanks for being around !

HWmonitor / afterburner showing temps under 60° but giving diff reading, i think thats normal since the variance isnt huge

no question of me criticizing you...I've just started and there's a long way to go

^^ testing the stability of gpu OC using gpu hungry games or benchmark apps makes more sense than to use some gpu stress test apps.

Use Metro 2033 benchmark ( 10-15 pass ) and games like BFBC2 ( play the uprivr mission), BF3 for 2-3 hours - if they are are running crash free your gpu OC is stable.

If you need to showoff you can push the clock/mem speed a little more as 3Dmark 11 will pass through the gpu test.

 

[Mr. Officer]

^^showoff as of now absolutely not...but when I build a real machine, maybe

its more of a learning curve moreover want to check for my myself whats the diff it makes to performane...have played COD-BO for 6-8 hrs after OCing to 875/1150 and no problem !

well my real overclocksclocks are 1000/1406mhz but can not post that with 3DMark's results because i don't want to buy those things (as well as i don't want to download because of their large sizes and i am using internet via mobile )

I will let only the screenshot do the talking

Cool ! You've got a king of cards and I've same too

I am running the same GPU (Sapphire) and Rivatuner doesn't even detect its drivers because the GPU doesn't support DX11. :\ Also, its a sucky overclocker.

 

[Skud]

A Sapphire nVIDIA card? Are you kidding?

 

[topgear]

^^ he must have a Sparkle gfx card.

@ ram22693 - post a gpu-z screenshot of your gfx card.

@ thetechfreak - a picture ( screenshot in here ) may say a thousand words but it's not always enough - do edit your post according to the thread rules - there's some important details are missing.

^^ where's the 3dMark screenshot ?

 

[Hrishi]

Well it might not seem useful ,but just out of curiousity .
"Is it possible to overclock the IGP present int APU using any application ??
What are the chances of messing up with the CPU too in the process , if possible ?".

I have read about the turbo in Intel's HD4000 and AMD HD6000 series IGPUs. Is it some sort of overclock or something else ??

Although I know overclocking an IGPU is a poor idea but *_O.

 

[topgear]

^^ If you OC the APu the Gpu core will be automatically OCed or else if your mobo bios supports you can select a gpu frequency from there as well

 

[Hrishi]

thanks for the info Topgear , but I have a doubt.
What is the functioning of Turbo frequency in Intel HD4000 and AMD 63xx IGPUs. ?

Since their base frequency automatically jumps from say 500 to 700 mhz , will this boost the CPU clock too , as the vice-versa is true as you said. ?

I was wondering this because AMD E-450 has a fixed clock rate of 1.65 ghz and the HD6320 IGPU has turbo of ~500 jumping to ~650 approximately.
How does the GPU turbo affects the CPU., if any?

 

[the_conqueror]

^^ where's the 3dMark screenshot ?

Is that also needed ? I thought gpuz validation would be enough. Will do it when I get time.

 

[topgear]

^^ yep, do this little favor - it's good for this thread.

It won't affect the frequency of cpu cores.

^^ I would really like to see some 3DMark score @ 1150/1300 Mhz speed and list the same.
