Moving to HD7970's, do these have voltage control?

post #1 of 8
Thread Starter 
Hello,

I want to try out the HD7970 CrossfireX, after a year with my GTX680 SLI, I feel like trying AMD again.

I was going to buy 2x HD7970 3GB reference, the following part number: 11197-11-21G

http://www.amazon.co.uk/SAPPHIRE-TECHNOLOGY-11197-11-21G-PCI-Express-Graphics/dp/B00B00PEAU


Do you guys know if this card has voltage control?

I'm not sure there isn't too much info on that card. Any reason you want that one over another 7970?

I want a reference design and voltage control so that I can watercool them and overclock them properly.

I'll just end up buying a pair of these: http://www.informaticagarrido.es/index.php?page=shop.product_details&flypage=flypage-ask.tpl&category_id=17&product_id=41144&option=com_virtuemart&Itemid=65&lang=es

I don't mind the coolers, I'm going to buy waterblocks!

I dont think you can find any reference sapphire anymore.The best deal is diamond reference or msi with the alternate pcb.

All the reference cards have voltage control

I have 2 vtx3d they are reference cards with the alternate pcb. I dont remember exactly:P

Yeah they are reference cards, almost reference PCB, just an extra phase, compatible with all 7970 ref waterblocks, I checked. biggrin.gif

So I'll be going for two of those probably.

I'd get the MSI Reference 7970. They are getting harder to find. Most of the 7970's have the dreadful blue PCB now.
