Hi hou

please sorry my english in advance

nowhere I found answer for all of my questions, thats why I ask you, the "inventors" of 6950 flashing :)

So here is the problem:

I have Sapphire HD6950 2GB with no BIOS switch (yes I know, Sapphire fu_ked with me so hard)



(yes this one)
It has got blue chip

Question is

1. is the card unlockable? I just want to unlock shaders, not to flash it with 6970 bios
2. does this card have the shaders? (it is only 24,5cm long) :eek:
3. is the unlocking of this card safe?
4. is it able to repair it if something screws up? (if yes how?)
5. is it true that this card has hardware lock of shaders and I should do something like this: ?



the code on the box is : PN 288-4E186-000SA / SKU 11188-00-40R

thank you very very much in advance :ohwell:

1. Don't know. You could try putting the bios in RBE and unlocking the shaders, then flash the bios to the card. It's possible it could fail and you will need to either blind flash it back or have a 2nd video card in your system to flash it back.

2. Card length doesn't matter. Not sure if it's unlockable.

3. No, not really if you don't know how to fix it. (see #1)

4. Yes. (see #1)

5. You could try doing that though you are always at risk in bricking your card.

If you want more performance, overclock the card. Unlocking the shaders yields in a 5% performance boost at most and you can get that from overclocking.

PS your English is good! :D

thank you very much

1. and whats the percentage succes of blind flashing? (and how does it work?)
2. and if blind flashing doesnt work the flashing using another ATI card is guaranteed 100% way of fixing?
3. and what type of bricking do i risk? just losing BIOS of this card or burning it (or something like that - software unfixable)
4. and please could you tell me what are optimal clocks to get maximum from this card? or in what ratio should i increase memory/core clocks?

thank you very much in advance

#1. If the card is just BIOS bricked, then i think you have a pretty good chance of a good blind flashing recover.
#2. If it doesn't work, try again. If it doesn't work after 2nd try and if your card is only BIOS bricked, so the chances of a good flash with a second video card are pretty the same as #1.
#3. There is always the risk of killing your card for good if a wrong BIOS is flashed. Just make sure to remove any OC in your PC, and close any unused programs that are running at the background if you don't need them. Make sure you won't have any power breakdown.
#4. That, i think you have to find it by yourself...

Note: I'm not an expert but I think what i said is correct...

-Results may vary
-I have no factual numbers for you
-There's always a risk in irreversibly damaging your card
-In what way it could get damaged, I don't know.

...
Well, it's just like you turn on your PC with a bootable device with Atiflash.exe and a good BIOS. Once your card is damaged, you won't be able to see anything in your screen.

You'll have to guess when the boot has been completed and then just write in your keyboard the requested commands to flash the BIOS...

I guess it's it!!

1. so there is no 100% guaranteed way of ressurecting the card after something goes wrong?

1.5. - so if blind flashing doesnt work there is no reason to try to flash it using second card? it is fucked for good?

I thought that flashing through the second graphic card is 100% guaranteed way to repair it.

2. And if I try to repair it using another card must it be ATI card only?

2.5. I have Nvidia 8600GT too, wouldnt it work?

3. and how could I flash into card wrong BIOS? if i modify it just via RBE there is 100% chance that it is good BIOS (if the card replies, of course :) ) or not? :confused:


... card for good if a wrong BIOS is flashed. Just make sure to remove any OC in your PC, and close any ....
what is OC?

thank you very much

There is NO 100% guarantee on anything when it comes to these cards. It's a risk at the end of the day.

You can flash it with a second card, but again no guarantee . Nvidia cards will work fine, doesn't really matter.

To your question #3, sometimes something just goes wrong. There's never a 100% guarantee. If anyone tells you otherwise they are lying to you. You need to decide whether the negligible boost in performance is worth the risk to you.


OC = overclock
