Radeon HD 6950 shader unlock instructions

[bystander]

2 thoughts come to mind. Did you have the bios switch in the correct location (assuming it's one with a bios switch). Also, was the card in the 2nd PCIe slot? If it's in the first slot, you'd use a 0.

No bios switch on this one as far as I can tell. I'm using the same HIS 6950 as the previous posts. And yes, 2nd PCIe slot, using a nVidia GTS 250 in the 1st.

Did you try to boot to the card without the Nvidia card in the case after your attempt to flash the bios back to the original? Perhaps it did flash, it doesn't take long at all, just a few seconds.

It is possible you have a bad original bios save. You can get a copy online and try that instead. Let me see if I can track the location to look down for you. I think the link is on this post somewhere.

I did try booting with just the 6950 in, no luck. The thing is, it didn't say it was successful and required a reboot like it did after I had first flashed, it just quickly flashes the winflash load bar across the screen, no confirmation of success or failure.

I just tried your suggestion of downloading the bios off that list, and tried to use steps 10-13, only replacing original.bin (or modded.bin) with this file, which I copied/pasted into the C:\winflash folder-- http/www.techpowerup.com/vgabios/100666/HIS.HD6950.2048.110330.html

Again, no success. Think I should try to make a bootable flash drive?

Thinking about giving this a go. I have an XFX HD-695X-CDDC with no dual bios switch. Anyone give one of these cards a try? Purchased back in July of last year.

Did the hardware mod and was able to get it to flash. However still stick on 1408 DOH! Going to clear out the drivers and see if that helps.

 

[ryanhirsch]

I've already hassled poor bystander enough, so to anyone that can answer my question, and/or link me to a forum or guide on how to make a file so that I might execute steps 10-13? From research, it sounds like a DOS file?

 

[ryanhirsch]

Sorry, let me rephrase that; trying to make a file to put on a bootable USB, so that I can execute steps 10-13 (all command prompt associated).

I have not created a boot disk in over 15 years. I do not remember how, but I'm sure you could find a way with a google search. Once you do that, I would advise looking at my 2nd post with the special instructions for the MSI TF3. It has a zip file with all the tools needed to flash your bios, you just need to use the original bios (or the one you downloaded for your card) in place of the modified one.

I have to thank everyone who has contributed to this thread. I scanned this thread yesterday and thought I'd give it a shot. Guess what, I bricked both of my bios on my MSI R6950 Twin Frozr III Power Edition. So the second bios is not read only. After reading this thread about 100 times, I figured out my stupidity. Tonight I was able to reload the original bios on the left switch and unlock on the right.

Thank you all again!

Worked for me: MSI Twin Frozr II 6950: 1536 shaders. My human eye is waek, so I am left to question, while sorry to sound ungrateful and doubtful to this excellent guide. You mention that the Bios IS flashed, and that the shaders "unlock", but are you sure that they are functioning? I'm no techie, so I have no way to tell. QQ

that whay i want to flash the card becasue i dont have that whit my other card flashed to hd6970

Most tests I've seen done show about a 3%-5% increase from unlocking the shaders alone. You might try testing with 3dmark11. Not all benchmarks are the same.

To me then it's not even worth the hassle of unlocking it. I am not even going to bother with it. I just got my Saphire 6950 and the switch is right there and I will just leave it alone.
