How to enable additional shaders on Radeon HD 6950

[Ginnoskie]

OK I finished benchmarking. I think I got as much juice out of the system as is possible. Past 975MHz on my GPU and 5GHz on my CPU I really had to increase the voltages to get it stable, and despite going all the way to 1.4v on the GPU I couldn't get them running at 1GHz to my disappointment

I wanted to attach the link to the 3DMarkVantage score but for some reason I'm having trouble uploading the result. So I'm attaching screenshots here instead.

Wooohoooo..well really nice scores on those OC'ing but me i couldn't go pass beyond to 950/1375. benchmark are crashing but stability test are ok using kombustor, but it crashes in the middle of benchmarking using ungine heaven, 3dmark vantage and 3dmark 11..i dunno what's wrong with it..

I'm rerunning it now in performance mode and will rerun them in high settings afterwards. unfortunately my monitor is only 1920x1080 so I can't run the extreme preset. The thing is it's -15 celsius outside right now and I have the window wide open so my room is at about zero degrees and I have the case open so I get idle temps of like 15 degrees and load temps of 40 hehe. I think that's partly why it's so stable. lower temp means lower resistance, lower vdroop, and lower current load and ultimately a more stable OC. I'll be posting the new benchmark scores soon.

What I wouldn't do for temps like those... Your gpu load temperature is my ambient air temp! I'm sweating my ass off in the air con! Damn Australian weather...

i have a sapphire 6950 2GB (dirt 3 edition)
tried to change the bios (from the bios switch) and now windows can't recognize my card
tried ATIflash but it says "adapter not found" using ATIflash 3.89 flashing stock and 6970.
do i need to use earlier version ? like the 3.85 ? but can't find it anywhere ;(

i don't know if this been covered before but been searching the net for the past 4 hours.


Thanks !

You should have saved your OWN BIOS and used RBE utility to modify it. I had a couple scare like that, but luckily I have two cards so if one got fucked up I could always turn off that PCIe lane and boot up with the other one and then reflash it back to factory from windows. While it is possible to unlock the card to full 6970 shaders, you only get about a 9-10% increase in performance and if you don't know what you're doing you could end up with an expensive silicon brick with a voided warranty

well i didn't used RBE because there are error's and many unsuccessful unlocks to non reference card..try to mod you're own bios from w1zzards php mod script then use the cmd mode to flash you're card using you're own modded bios which is unlocked shaders only.

Also I'm getting 70c when I'm in full load because the ambient here is so hot it's like 29c ambient so it's very normal getting those temps..

I followed this tutorial.

But bios1 position on the picture was my bios2 position... I fucked one bios, and when i tried to recover it by switching bios while my computer was running, i fucked the other one.

I tried atiflash with dos command but i got the error "adapter not found"

Is there a way to fix my card or is it down forever ?

I did the same thing =(

i tried the bios bypass thing, didn't work =(

please let me know if you find anything!

Thanks

love this article

well its all working but i get occasional artefacts in my firefox browser :/ and small glitches in games but hardly noticeable.

my card is http://www.msi.com/product/vga/R6950-2PM2D2GD5.html

so what i can do? use that RBE to modify existing BIOS? lower setings?
or is it bios not compatible with my card ?

pls help

have u tried to do it from windows level (if u have built in graphics card in your motherboard)?

yea tried that but windows won't recognize my card

Try this forum http://www.overclock.net/t/1200348/6950-2gb-bios-flash-gone-wrong/10 might help a but

I wolud anything to fix it but i never experience this problem so sry but o try to look for some fix for ya as i got problems with my card too. And sry for language i prefer polish

 

[Ginnoskie]

have you tried the flashing through USB? maybe try that one..

i lowered core clock and mem clock to lowest and i stll get the same effect :?

use the Newer version of ATIWinflash then save you're original bios then flash you're card to revert back it original settings.

iv used ati_winflash_2.0.1.14

maybe if i try different bios ?? but where do i get them?

thanks for reply

 

[Ginnoskie]

Try these bioses on what it will suite to you're card

ok so i reverted bios to the one it was on card and turn on kombustor is this places on pic are normal? (now i dont get any funky spots in browser)

 

[Ginnoskie]

hmmmm maybe i should check out mine when i get back home after work..and i don't think that's an artifact..anyways have you tried those bios i send you the link?

ill will try now the 6950 check in kombustor then go for 6970 and check again

 

[Ginnoskie]

yup my card is flashed to 6970 until now..i will check at home after work then post if we have the same result. but so far when i ran kombustor i didnt see artifacts nor in games or benching..and it's running 24/7 stable..but i will double check it again..

 

[onehans]

ill will try now the 6950 check in kombustor then go for 6970 and check again

i tried 3 avaible 6950 bioses all of them does this funny collors in kombustor. i have checked google and other pictures shows that, so is got to be standard.

but i could not load 6970 bios from that link uv send. do i need to modify them to get it to work?
what i was thinking is to download 6970 bios of this model R6970-2PM2D2GD5 which is higher version of this one R6950-2PM2D2GD5 and load it on to mine R6950-2PM2D2GD5 but winflash sais "subsystem IDmismatch"

 

[Ginnoskie]

oh so you want to flash it with 6970 i thought you where referring to the unlock shaders only..yes on the link I've sent to you there are 6970 bioses there:

http://www.techpowerup.com/vgabios/...SI&model=HD+6970&interface=PCI-E&memSize=2048

..try one of them..and use the CMD mode it's much accurate than loading it directly to ATIWinflash.

and what commands do i need to drop in CMD? and do i need to use winflash? (i found commands just now in here http://www.tweaktown.com/articles/3762/sapphire_radeon_hd_6950_2gb_unlocked_to_hd_6970/index.html)

will it bring me better effect by unlocking it to 6970? or just shaders are enough?

ARTIFACTS solved got none in browser so probably i wont get any in games now YEY! it must been a bios then by flashing it to 6970 work as a charm, so i go get some game play experience and 3dmark11 test

oh and any chance to control core voltage in afterburner? if yes what is a save max vcore?
