ATI 6950 to 6970 Driver Recovery issue
 

Anyone been running into the ATI Driver recovery after a flash? Reinstalled the driver and ran DriverSweep to clear everything out. Tried both 10.12a and 10.12.

Mine seems to be only on some games. And doesn't fail when running Furmark or Heaven. But crash's on Sup Com 2/Trine, and a couple other games.

Standard 6970 Clocks at: 880/1375 and running at 12% Power.
Using TRIXX for the custom fan speeds.

What are you temps?
On first guess I would guess your card wan'ts more juice than average.

SonDoobious's needed better cooling.

Temps are average at about 70-80c depending on my room temp. Fan's set to increase as it goes, but this happens pretty much 2-3min of playing.

Yet other games work fine. Fallout 3 NV - Plays for hours on end, no issues.

Your temps sound good enough to me, I would try upping your voltage. That is my only suggestion, my 6950 does not get here for a few days (I ordered it last night) so I don't have much hands on experience with a flashed 6 series..

Good luck!

Thats the one thing I can't do is up the volts. The bar isn't adjustable in TRIXX. Set at the default 1.175

I believe you can modify the bios to do that.

Do you have Trixx 3.0 or 3.0.2? 3.0.2 has more support for the 6900 cards and you might be able to change voltage with it.

Hi mate,
Same issues, unlocked 6950 to 6970. stable a +20% 930mhz and 1375mhz in furmark, Unigine, BFBC2... Crashes after about 1 hour of Supreme Commander2...
Running these under water, max temp after 1 hour of furmark 1920x1200 x8 aa gave a max temp of 50 Centigrade...
Sounds to me like driver issues... Seems unlikely due to voltage as Furmark gives these cards a much harder and constant ragging than any game would (esp sup commander) which is more CPU limited I was told...

I finally got mine stable. Unable to OC but stable at 10% and 880/1375. Anything more push's it to crash in Sup Com 2 and Trine and who knows what else. Theres some new drivers coming out soon, hopefully they have those things tweaked enough.

well have the issues of crashing is probably due to trying to overclock the damn things seriously just unlock the shaders leave the clocks at stock 6950 memory is rated at 1250 so your basically pushing 125mhz higher and this isnt desktop memory where u can change timings 9/10 the ram just cant cut it at those speeds then again ram speeds probably wont give you any major performance gains AMDs gpus have been ROP starved since the 5800 series not bandwidth starved. get the core as high as you can stable and leave ram at stock 6950 speeds. the difference between 1250mhz and 1375 is probably going to be no more then 1% maybe 2% at best. Also with 2gb of ram drawing power you can probably eek out slightly better power consumption with the ram at lower speeds since at least in my experience with dual monitors the cards ram always runs at 1375 on my 6970s and never drops down so lowering the ram speed will affect idle and load power draw with load probably being 15w or more difference but thats just a rough estimate.

you have to remember that the 6950 was not a 6970 for a reason they failed at 6970 speeds and shader count, it is luck of the draw.

like crazyeyesreaper suggested, perhaps its a memory problem, where some 6950s can't handle 6970 timings

I think you could find a solution browsing through this thread (may need to look deeper)
How to enable additional shaders on Radeon HD 695...

That might be true for some but obviously not all or else so many cards wouldn't successfully unlock from a simple firmware flash. ATi did the same thing when demand for the Radeon 9500 Non-Pro cards exceeded the supply of defective 9700 chips, they started using fully functional cores disabled through firmware. When demand for the X800GTO exceeded supply, they put the later X850 cores on some of them and disabled them through firmware. Now that the word is out that the 6950 is unlockable, I expect they will start laser cutting the cores to preserve their profit margins on the higher end parts.

Most likely some of the AMD partners are using less expensive memory chips that don't overclock as well on the 6950 cards. I remember when my 9500 unlocked to a 9700 I was never able to get the memory clocks quite up to even stock 9700 levels let alone 9700 Pro because they were lower speed chips. I had to be happy with the unlocked pipes and a mild core overclock.
