Asus HD 6950 DCII 2GB

post #1 of 5
Thread Starter 
Hello,


I bought a Asus HD 6950 DCII 2GB yesterday for my new rig. I have reading up on unlocking this card and noticed some of the cards are laser cut and cannot be unlocked.
How do I know if my card is laser cut? Do I have to look at the serial number or something?
And after many unclear discussions: Is the switch also a dual bios switch or not ?

Greetings,

Sergov

"Like all other HD 6970 and HD 6950, this HD 6950 DC2 is equipped with a dual-bios: the first bios can be flashed (read/write mode) and the second bios is a security bios (read only) you can use in case of a bad bios flashing. Thanks to this nice feature, you can safety flash your HD 6950 bios and get the HD 6970 performances"

I guess you've read one my posts in this thread

To understand whether your card is laser-cut/not-unlockable, you need to try to flash it first. Even it is not unlockable, it wont damage your card. Behind your card there should be something like "Rev 1.00" and ASUS still producing with the same revisions... For example I bought my GPU (same model) on June, the card was unlockable but it was faulty card (I did learn that they sold me the refub. one) Anyway after 5 painful weeks of RMA to receive my brand new one from ASUS, I decided to unlock it in first day and it was successful again. Whether you bought on June or October/November, the unlocking works like a lottery. To give some more detailed example: check the serial number:

The one I bought on June starts with B4******* (4th generation)
The one I received new from ASUS on October starts with B9******* (9th generation)
I think you wont get any problems. (difference between old and new cards are just the generation is different, revisions are the same)

The switch on the card works for DVI-to-Display port but the link I gave you at the top of this post will show you that some of the 6950 DCII users found out that It also can be used for bios switch (interesting but it works for me aswell). Probably ASUS using 2 different bios to control DVI and Display port switch on HD6950DCII's.

Don't forget that flashing is always risky, me (THE I ReD) and Overclock.net are not responsible of what you are going to do...

Make sure you do some research before you flash it and Good Luck!!
If you manage to get unlock it, here is how it looks like:

I believe the "B4" or the "B9"in the serial # is related to the date of manufacture:

First digit/letter range for year: 1-9 & A,B,C

Second digit/letter = month.

B = 11 as in 2011
4 = fourth month of the year.

B9CV... -- translates to the 9th month of 2011 and that it's a videocard.
