PowerColor 6950 Non-Reference Overclocking

post #1 of 22
Thread Starter 
Hey guys,

I have just bought a PowerColor 6950 which has a custom cooler but i believe has a reference board:



I have managed to unlock the 1536 shaders using the original bios then overclocked the card using MSI Afterburner to 850mhz core and 1350mhz memory (thats the maximum allowed in afterburner for memory)

Everything is running fantastic and never goes above 59 degrees under load playing crysis 2 for hours. However, as this badboy has a customer cooler i would like to push it a bit further without frying it.

Afterburner lets me change the voltage to a maximum of 1300. I have tried 1175 and bumped the core up to 900mhz and its stable playing crysis and adds about 3fps extra on just cause 2 benchmenks. Maximum temperature i saw was 63degrees and fan speed on 50%.

Do you think its safe to run 900 / 1350mhz @ 1.175v with these temperatures or am i better off sticking with 850 / 1350 @ stock voltage?

Its a great card so far. Big upgrade from my old GTX 275, theres a few issues with black ops and GTA IV but thats the games not the card

you'll be fine at 900/1350 at that voltage with that cooler and if you can shoot for 1000MHz core clock. I can do 965/1400 @1.21v with my Scythe Musashi and Swiftech MOSFET heatsink's. You should also keep an eye on your VRM temps, use GPU-z for that.

I did run Kombuster for an hour @ 900 / 1350mhz voltage 1.75v and maximum temperature was 68degrees, fan speed 55%.

I may try and lower the voltage to see if it's stable at those clocks. 965 /1400 @ 1.21v that's impressive!! For some reason my max memory clock is 1350mhz. I expect you can unlock it changing the bios but i'm a little worried as its running well at the moment and as its not a reference card i'm unsure if further flashing will be stable

It's a reference card. See that small switch? It reveals that it's an AMD reference design.

I believe so mate. I have unlocked the shaders but i havent flashed it using a 6970 bios or anything else.

I have a problem with MSI Afterburner - It doesnt apply the overclock at startup or when pressing apply for the first few attempts. GPU-Z still reads stock values. After a few manual attemps it seems to work. Anyone else had this issue? (I have selected 'apply on startup'

I can only go upto 850mhz / 1350 on stock voltage so i will try and ramp it up tonight to see if i canget a stable 900+ on the core...whats the max temp for these badboys? My old gtx 275 used to reach 95degrees all the time and still ran fine for years but it hated being overclocked! ...anyone got any tips for increasing the voltage? Do i do it a small amount at a time? I sound thick but i'm assuming 1175 in afterburner is 1.75v? etc

You also have to add this to the EULA line in the config:

It's a Power Color PCS++; not a reference card.

Wrong. There are several 6950s non reference which comes with a BIOS switch.

Its not a PCS++, The cooler is slightly different (PCS++ has meshed grills on the cooler) and has PCS++ Branding on the box. Mine was just in a normal plain PowerColor Box
