[calvinbui]

videos are still buggy though, i would give you the link but its actually porno lol

I FIXED IT!

Reinstalled windows and Catalyst. I haven't installed the hot fix as my probs occurred after installing them. I will wait for next set of drivers.

So am putting it down to corrupt window registry.

Single card now back up to 42FPS/1044.

Thanks for the help guys. :thumbup:

One for the memory bank.

The second card will have to go back in tomorrow after work.

glad to see that you fixed your Crossfire issues: i had two 6950`s @6970`s installed either this weekend and sometimes weird thinks happening: e.g. Grant Theft Auto 4 flickers all the time in menues and refuses to adjust any resolution or quality settings in game. Alien vs. predator DX11 benchmark at first start refused to run on two GPU`s, than i restarted application two times and than it worked, but i had some rendering issues (fog/light scattering/flickering) therefore i went into the driver and forced AFR-friendly D3D game and than the flickering was gone... metro 2033 and 3dmark11 working perfect in Crossfire mode...also does Stone Giant benchmark and lost planet 2 dx11 mode, unigine heaven 2.1
refused either to use 2nd GPU, after some restarts and switching to fullscreen it worked.
also if you use tools like Afterburner 2.1.beta5 or trixx 3.0.2beta or gpu-z 0.5.0 i got lots of BSODs while changing clockrates or fan profiles, usually i could adjust the first gpu, but when i wanted to sync the 2nd GPU to the first one -> reproduceable immediatly crashed, especially if i adjust with MSI afterburner on the desktop and slide the sliders and hit apply -> BSOD, but if i write clockrates into cfg and assign a hotkey, than i could switch to overclocked states while playing without crashes -> long story short answer: drivers and tools are still very buggy for crossfiring overclocked modded underestimated cards like hd6950...


nethertheless, crossfirescaling is impressive: nearly doubled min fps in metro 2033 vs. single gpu, same in Lost planet 2....also stalker seems to run with less microstuttering than with my previous hd5870 setup...but powerdrain is bad: with phenom x6@4GHz and both 6950@6970 @950/1500mhz my power meter showed ~600watt consumption while playing metro 2033...before with hd5870´s it was around ~525watts

Hey guys,

to all who tell others to just go and flash the full 6970 bios:
You say its nearly always works, because u can run furmark for hours and 3DMark and Crysis ect.

But i have to tell you that i experienced the same witch the 6970 bios, but when i tried to play Starcraft II it always crashed.
Lowerings the rates only brought me 2 or 3 minutes more before crashing.
Only the modded 6950 bios (free shaders, same voltage) helped me out there.
I think many of you would have the same problems if they had SC2 to test it (Ultra-Settings), but its still the only game i had crashes so most of yout wont mind anyway
I have to see what futturegames bring (Crysis II, The Witcher II)

You can add another successful Sapphire 6950 to 6970 Asus bios flash to the list.
Currently running 915Core 1375 Ram. I ran Heaven benchmark about halfway through at 940 core but it crashed, going to plug in the extra 4 pin power to my board tonight and try again.

I run SC2 without any crashes. Given my frame rate is low for my specs (36-48 fps @ 2048x1056). I do get crashes in Oblivion though.

hi all,i just joined today after buying one of these radeon 6950 cards,succesfully unlocked to 6970 bios.. card is xfx radeon 6950 hd

 

[sy5tem]

just got my XFX 6950!

just got a huge problem! this was a replacement for 9800GTX+ , now with 9650 install i get PCI option rom poblem (my ich10R won't work)

was so anxious to get bios mod going damit!

 

[dom99]

Just installed my VTX 6950, looking good at the moment I was really impressed with the quality heavy feel of the card. Going to run some benchmarks tomorrow but not going to push it untill Ive been using it for a few days to wear it in lol. My gf is playing the Sims3 at the moment and it runs sooooo much smoother than the 6870, im thinking the 2gb memory is useful with the insane amount of textures in this game. But ill be using it on BC2 and BO tomorrow

Just got my Sapphire 6950 and unlocked it to 6970.

Everything working fine so far.

Just had a strange issue with the ram staying locking its clock rate at 1375, despite it being set to 1275 in Overdrive. It read 1375 in both CCC and GPU-Z, and would not change even when I adjusted the settings in CCC Overdrive.

I only even noticed it because suddenly my mouse cursor glitched out. Looked like a strip in the middle of it was erased and moved off to the left of the pointer, and there was a skinny vertical line off to the right of the whole mess. It fixed itself after closing everything and clicking on the desktop... but even that seems strange, haha.

Anyone else have issues with the clock settings not staying fixed?

Edit: It just happened again... seems to occur every time I open Hulu now... guessing there's an issue here. Is it safe to use it like that?

Thanks for any thoughts,
Aip

Not directly related but I noticed that CS 1.6 in DX9 @ 2048x1156 8xmsaa gives me around 72 fps. CSS DX9+ @ 2048x1156 8xmsaa gives me 150+ fps.

I thought it was interesting.

im starting to get rendering artifacts now even after going back to the 6950 bios
reinstalled the drivers, 6950 all stock driver settings and clock speeds
i get errors in 3dmark11 and heaven dx10 mode
you can really notice it at the top of the screen in the second demo of 3dmark11 but i cant seem to be able to get any screenshots of it

theres a few small places in heaven dx10 that you can notice it flicker on and off

it was all fine for a while but i started to notice it after about 5 days @6970
hopefully i can return it for another but i dont think my chances are good

you win some and you lose some i spose

So 6970 bios run great for a while, but it's killing the 6950 day after day, i am running the 6950 Xfire unlocked shader @ 840 core 1325 memory , i hope havn't trouble like this :s

Because i have some litlle bug, in single mod the 2 6950 run fine in all game (Crysis, BBC2, Metro 2033) but in Xfire in have some graphics bug in BBC2 like a very short lightning black screen, someone have the same bug ?
Other trouble in BBC2 like the death screen and victory screen is very laggy in Xfire but fine in single !
I hope it's just a driver or game issue but in crysis i have some rendering error like twinkle sky ! of course no problem in single mod with the two 6950 !

I have the 10.12 driver , and a good PSU, Cooler Master Pro M 1000 W so anyone have trouble like me in Xfire ?

 

[dom99]

yeh Im not going to the 6970 bios im going to run the 6950 unlocked shader version, too many stories of long term instability. I dont even need the extra performance im just greedy lol

But I have a problem, and it looks driver related. I havent done any modding yet and my idle clocks are 450MHz core and 1250MHz memory. It is strange because when I installed it yesterday I was seeing something like 250MHz core on idle. Hmm I have seen other people in this thread with clock issues but anyone care to shed any light on this?

 

[Kaali]

Anyone have this rendering error on BBC2 with single 6950 with catalyst 10.12 (the grey line over the helmet of the last right guy )?

I am going to try the 10.12a to see what happens !

 

[monte84]

I successfully unlock my Gigabyte 6950 however after reading of people getting artifacts I restored the original bios. Just long enough to run some benchmarks. Those who got artifacts after extended use, what brand was the card?

[Kaali]

2 Sapphire for me :s

 

[tecnoworld]

I think that 6970 bios could eventually damage memory. That's why I went for the modded 6950 bios, that just touches the GPU.

 

[Kaali]

Maybe , maybe not , i havn't use the 6970 bios , i just use the 6950 unlock bios and i am getting rendering error so ... even if i flash back to 6950 bios

I try the 10.12A same rendering error on BBC2 , could anyone who have 6950 and BBC2 tell me if you have the same rendering error ?

 

[tecnoworld]

this is very strange; could it be caused by defective shaders? but, of course, flashing back you should inhibit them once again...don't know, really.

 

[Kaali]

I guess my 6950 are damaged , but it's wierd because i have the same error for the 2 !

 

[tecnoworld]

yes, that's totally odd...did you try reinstalling windows?

 

[Kaali]

No i don't , i want to avoid but i am thinking of !

 

[tecnoworld]

you should either do that or try your cards on another machine...

 

[dom99]

Can anyone offer a reason why my 6950 idle clocks are 450MHz core and 1250MHz memory? Before modding, tried reinstalling drivers and no fix
