Is my 7950 card reference and capable of using 7970 water block?

post #1 of 11
Thread Starter 
Just got powercolor 7950 reference card with the pbc R19F 1.0, and saw the xspc 7970 new style block looks cool, but it does not mention if it can be used on 7950......

I searched a lot and saw ppl say the pcb version is a typical reference card shared by 7950 and 7970, so I assume it should be OK to use the new sle water block, but as a newbie, i still need some experienced use to confirm this.

The block I am referencing to is

Ant help is appreciated.

To use 7970 ref water blocks, your pcb must look like this CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), default quality

If your pcb looks like this CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), default quality, you must use 7950 reference water block


Can you find something like this "AX7950 3GBD5-2DH" serialnumber on your 7950 package?

If its the AX7950 3GBD5-2DH then it uses the 7950 PCB and will not fit a 7970 waterblock. You need a 7950 water block.

The XSPC is only for the 7970 PCB

I think there is something printed Part NumberAX7950 3GBD5-2DHV4, the one with the boost state

The original powercolor 7950 has the past number ax7950 3gbd5-2dh

So in this case does it mean I cannot even consider those blocks says 7900 series or 7950/70

And I will take the plastic parts and fan off to see what it looks like,
Thanks both of you for your reply

Turn your card arround, see if there's any of those holes that I've pointed out. If you can't see any, then you can't use any of those block says 7900 or 7950/7970. You have to buy a reference block designed for 7950.

I've checked, your card has reference 7950 pcb, just pick up a block for 7950, it should fit without a doubt.

@Sammyboy 83

you are right, I have to get block designed for reference 7950....

my only concern is I might change video cards sooner or later, so I am also considering the universal GPU block, are they efficient?

I am thinking EK-VGA Supreme HF Bridge Edition, but seems for 7950/70 they all need the Cu Adapter to make the block work correctly.

Universal Blocks cool Slightly Better. With my experience though. If you do, never forget to buy more Small heatsinks for the Vram.

We have virtually every PowerColor card listed in the CC: http://www.coolingconfigurator.com

R19F is HD7950 reference design therefore only EK-FC7950 and similar water blocks will fit:

Thanks, that's good to know, I thought the FC might be better coz it's bigger.....it seems I judged too soon.
now I am considering two core block options

Watercool HEATKILLER® GPU-X³ Core LC
http://www.aquatuning.us/product_info.php/info/p13597_Watercool-HEATKILLER--GPU-X--Core-LC.html

and

EK Water Blocks EK-VGA Supremacy Bridge Edition
but I don't know which one has better efficiency when I parallel 3 blocks in my system.

EK, glad to see your reply and I do have a question, what's the difference between the Supremacy and Supreme HF GPU block? Can't really find too much info via google.rolleyes.gif, Care to teach me a lesson? thanks.

The Supremacy is the new model ... supreme HF is the old.
