7970 without voltage lock

post #1 of 3
Thread Starter 
Friend of mine is doing a build and I recommended the 7970 based on how much overclocking room it has with voltage mods.

Now I'm having trouble finding a decently priced one that isn't voltage locked.

Xfx and Gigabyte are for sure.

The Asus Matrix is not but out of stock in Canada.

Sapphire I'm not sure about but any RMA has to go through a second party that charges a fee for doing so.

Can someone point me in the right direction?

Thanks.

For guaranteed unlocked voltage a reference HD 7970 card with a reference cooler is the only option. But the issue is what if you get a overclocking dud. also the reference cooler can get loud if you want to hit 1200 Mhz.

The sapphire HD 7970 Ghz Vapor-X is a good option. the Ghz have higher stock voltage (1.25v) and can hit 1150 - 1200 Mhz even at stock voltage.
