I would check with OCUK.

I bourght that exact card and the cooler was NOT reference, it's a 2 slot design sililar to this: Asus ATI Radeon HD 4850

ive sent a web note hopefully they can clear it up for me thanks for trying to help

It doesnt matter whether the cooler is reference or not, just the actual PCB, he'd be taking the cooler off for WC anyway

got a reply back from my web note they said i should contact the manufactures and ask, has anyone got a 4850 under water at the moment

Here is a poo quality picture of mine from last year, back when all bar the IceHQ one was using the awful stock design.

No problem connecting a gpu block to it. As you can see, some bodging for the heatsinks on the vrms(sp?). They get seriously hot, and I would recommend much bigger sinks than the usually small memory ones about. I cut up an old Intel P2/P3 era heatsink.

Cant help you on your quest to find out if the non reference PCB's out now have 4 nicely equal spaced holes for gpu blocks.

Here's an image of a reference 4850:

Try and find some one with the card that you want and ask them to take a photo of the back of their card. If the screw holes and GPU/RAM/Power circuitry locations are the same then you'll know it's reference.

i'm usng an old asetek cpu block from about 8 years ago. works quite well tbh and for the vrm's and ram chips i hacked up the reference stock cooler and cut out the gpu section for my block to fit in.

i have since got rid of that card and bought a sapphire like in the OP but like i said it came with an orb cooler and the pcb is blue too. i am now using the same water block and have bought some ramsimks http://www.overclockers.co.uk/showproduct.php?prodid=SY-006-AK&groupid=701&catid=57&subcat=399

the holes for the heatsink are the same on reference as they are on non reference i think as i used the heatsink back plate thing from my reference card on my non reference card and it fit the holes perfect.

i sent sapphire a query this morning about 1am and got a reply at 5 am good service they said there early boards were reference and now they use there own boards and i should get in touch with the retailer about which boards they stock are reference, im going round in circles here
