ATI 6950 Unlocked to 6970 Texture fill rate?

Ok guys Im going to try a few things now (Just woke up how pathetic lol), First thing is im going to use a different PCI-E slot aswell and changing the x2 6 pin connnecters, and formatting my system and installing slightly older drivers than the ones Im using and try and OC again.

What ya think guys, good plan of action?

Guys, quick question for you 6950 owners (didnt want to start a thread for this), will it fit in an antec 300 case?

Just and no more:

As the 6950 is the same size as a 6970 that's been used in the pic.

Ok im taking my thread back!, lol. I have just come back from my local component shop with a brand new 780w PSU time to test with a diff PSU.

Will update on results.

Don't worry, I was awake till 10am and I've not been up for long lol.

I'm bloody 29 and shouldn't be able to pull all nighters :D.

Aye mate it's a good course of action. Best trying a few things before sending it back. It's possible you've just got a duff card but the card is perfect stock locked and unlocked. I've also seen more than a few powercolour cards overclock roughly in the same area as my 6950 does so I think again that something is wrong here. I just hope something happens positively today.

Good luck mate.
 
J.D, I couldnt get the card past 880/1325 even when bumping up the voltage to 1.275, I have put together my old rig:
QX9650
Asus Striker II eXtreme
4GB Corsair DDR 3 (will add timings)
the new 780w PSU

Right so completely different system which means I have changed EVERY component apart from the graphics card.

Will update results.

Oh..so your card is responding to V. If so disregard my ^ post. I was of the understnading that you were getting NO response to V changes, couldn't go over 840 core no matter the V. If you are getting better clocks with increased V then you are using correct V registers.

My guess is you are using the wrong voltage registers.

Test this to raise your V:

If that works make a permanent fix:

Use 'VDDC_VT1556_Defaults = 9A 51 9B 80' for XXX in the above post.


You might also try changing V with RBE. It sounds like in your case VID3 (which is what most use) will not work and you'll have to change VID4.

Also leave PowerTune at 0%.

Could you just clarifiy what you meen by You might also try changing V with RBE, Also i will try forcing constant voltages now.

Yeah well I was wrong 880 locks up now, the only stable clock i can manage is 840/1325

RBE is a BIOS editor. You really shouldn't need to go that route though, if we can get your V up in AB.

When you raise V in AB are you seeing increased load temps?

I dont get a chance for it to increase to the point where I would notice a difference, I just forced constant voltage and tried again at 1.175 880/1375 and locked up right away. Im starting to get fed up of the ****ing thing. -.-
 
The card in a completely different machine makes absloutley no difference, Really does look like this is just a bad card.
