No, all AMD cards, reference or not, have marking to show the original PCB manufacturer smile.gif

Hope this helped, 512

7950 ref cards use 2*6pin power, if its 8&6pin its ref 7970, this email I got from watercool might help you

Hello,

the compatibility information are right. The first samples of HD7950 from AMD (test samples and development samples) came in HD7970 layout.
Therefore our block got the name 79X0. With release the 7950 came with its own layout. So we have changed the compatibility to HD7970 only. Our block will not fit on the HD7950 reference design (zig-zag line of capacitors). I apologize.

This is for the heatkiller blocks

Also using coolingconfigurator might help

So what cards are compatible with water cooling? Man AMD really made this so damn confusing frown.gif

Basically you need to be very carful when ordering your block, get the card first and see what it is, EK have blocks to fit reference 7950 (2*6pin) but they are very hard to find, and some 7950's are actually using 7970 ref pcb's so waterblocks for 7970's will fit those

For a card to use a reference water block you have to take the fan off and take a loop at the PCB yourself. You shouldn't always trust the internet on this because companies have so many revisions of their PCB's that their changing all the time. Here is what a reference 7950 PCB looks like:

So I have to buy a card, pull the heatsink off to find out if it'll be compatible? Looks like I'm giving up on this and buying a couple 670's frown.gif

Also, I can tell you for a fact that the MSI TFIII 7950's are shipping with a reference PCB. I bought one recently along with a Sapphire Dual-X and the Sapphire is reference too. If I were you I would by the TFIII and you can buy it knowing that it is reference.
*For all who are wondering the TFIII is not shipping with the with the 7970 PCB anymore.*

no u just need to find out what its power requirements are or go to coolingconfigurator to see what blocks are compatible, if no blocks are shown as compatible on there is more than likely a non ref card
