You can discuss any and every thing related to Discrete GPU or Graphic Card over clocking here - when you have reached nice speed by ocing the gfx card and you want to show off this to the others just post in here according to the rules and I'll list it in here ;-)

Before OCing read this :

> I don't take any kind of responsibility on how the information mentioned in this thread or posts will be used.
> If you want to OC the cpu or any related components do it at your own risk.
> Make sure you have proper ventilation and cooling equipment.

Rules :

Add a GPU-Z and 3DMark / 3DMark Vantage / Unigine Heaven score screen shot and post in this format :

GPU :
Manufacturer and Model Name ( Optional ) :

GPU Stock Speed :
GPU Overclocked Speed :
GPU Core Volt : Stock / If tweaked mention the value

Shader Clock ( Optional ) :

vRam Type :
vRam Stock Speed : 1100 Mhz
vram OCed Speed : 1150 Mhz
vRam Volt : Stock / If tweaked mention the value

Cooler : Stock or Third Party/Special
Bios Version : Stock / Updated ( version ) or Modified
Software Used for OC :

Additional Notes if any :

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Here's an example post :

Nice ... but do you have to add a GPU-Z and 3DMark 06/3DMark Vantage or 3DMark 11 score screen shot ;-)

GPU : AMD Radeon HD6950 1GB
Manufacturer and Model Name : Sapphire HD6950 1GB

GPU Stock Speed : 800 MHz
GPU Overclocked Speed : 920 MHz
GPU Core Volt : Stock 1100mV/1149 mV (see note)

vRam Type : GDDR5
vRam Stock Speed : 1250 Mhz
vram OCed Speed : 1300 Mhz
vRam Volt : Stock

Cooler : Stock single fan
Bios Version : Stock
Software Used for OC : MSI Afterburner

Additional Notes: Although 3DMark11 runs properly, Kmark (part of MSI Kombustor) was showing some artifacts although the test completed successfully. So started a GPU burn-in in Kombustor and it locked up. Upping the core voltage to 1149 mV solves the problem.

950MHz reached @ 1.2mV. Will post screenshot once I reached the ceiling. ;)

In the general tab there's the option to unlock voltage control. Try.

OK, TriXX is fine too.

GPU : AMD Radeon HD6950 1GB
Manufacturer and Model Name : Sapphire HD6950 1GB

GPU Stock Speed : 800 MHz
GPU Overclocked Speed : 1000 MHz
GPU Core Volt : 1299mV (see note)

vRam Type : GDDR5
vRam Stock Speed : 1250 Mhz
vram OCed Speed : 1300 Mhz
vRam Volt : Stock

Cooler : Stock single fan
Bios Version : Stock
Software Used for OC : MSI Afterburner

Additional Notes: Can't push the core any further but reached 1GHz nevertheless, even though it was not very stable, Vantage on High threw up an error, Final Fantasy XIV was choppy all along and Heaven finally locked up.

Touching almost 2K in extreme, not bad for a sub 15K card, I guess. ;)

Using AFTERBURNER I've raised the core clock from stock to 875 mhz and memory clock to 1150.now if i raise the core clock any further the unigine benchmark wont complete. after OC gpu temps are 58° -60° c

when i raise values in afterburner values in GPU-Z change simultaneously but should you restart pc after every tweak for it to take effect ?

At stock speeds I get 29.2 fps in unigine benchmark
At OC speeds I get 32.6 fps in unigine benchmark

now core volt and shader clock are locked [tried the settings tab in afterburner, doesnt work] anyway of unlocking these and will that provide any extra performance ?

how good is kombuster in msi afterburner or please suggest other user friendly utility.

thanks

EDIT

tried to make changes thru catalyst control center still cant unlock core volt...

on the other hand raised fan speed and ran unigine and this time got 37.8 fps !!

HD6670 can't be oced by changing volt values using software apps like Trixx or AB - so you will have to happy with the stock volt.

Keep an close eye on temps when OCing any gpu ( post your load gpu temps ) and I won't recommend running Kombuster / furmark like app - don't criticize me on this - just a personal suggestion to keep the gpu safe ;-)

Try running 3Dmark gpu test and also try OCing the mem clock speed.
