Hi, anyone have list of which models of 7950/7970 have unlocked voltage? I noticed gigabyte are locked, what about msi, asus, sapphire, his?

I know that the Sapphire Dual-X are unlocked. I think the Sapphire Vapor-X are also unlocked but not sure. And maybe MSI Twin Frozr too.


Its the one I would buy. Those are unlocked.



Suppose to be unlock, I'm 99% sure it is


This is a feedback from a MSI TwinFrozr User




One of my tips I can give you is checking the feedbacks on newegg.com. Each cards have many feedbacks, check them and judge byyourself if its locked or unlocked.

It would be easier to list cards with a locked voltage. Most 7950 and 7970s don't have a locked voltage.

I found a lot of false reports in product reviews such as neweggs. AMD reference boards mostly come with a dual bios switch. Sometimes one bios is voltage locked as where the other is not. So It could be that uneducated consumers report back locked voltage without trying the other bios. Most reference boards will be unlocked and can be identified by AMD lettering just above the PCI-E contacts.

I can report that my SAPPHIRE 100352-2L Radeon HD 7950 is unlocked.

Gotta be careful with Sapphire. Not all of them are unlocked, mine is locked. Sapphire HD 7950 Vapor X OC.

That's the 7950 with the 7970 PCB and 2 8 pins.

EDIT: http://www.sapphiretech.com/presentation/product/?cid=1&gid=3&sgid=1157&pid=1547&lid=1

Just for clarity this one is LOCKED. smile.gif
