Topic: Official R9 Graphics Card Voltage Locked/Unlocked list - page 2. (Read 31540 times)
Has anyone tried VBE7 on the R9 290 Reference cards?
there is a guide for this?
On linux what are you guys using with "unlocked" GPUs to alter voltage? atitweak?
A lot of guys just do it in cgminer with; --gpu-vddc 1100 or whatever voltage.
I have to say though, after reflashing all my cards with VBE7 I will forever do it this way from now on. It's rock solid and you never have to worry about messing with it in software as the software doesn't always do it right and isn't always reliable.
To the guys who made VBE7 "Darkhmz, DroiDMester, & whoever else"; you guys rule and many thanks

The Sapphire Toxic 280x can be bios modified to lower the voltage.
how?VBE7. I can confirm it does work on the 280x toxic as I also did it yesterday. I'm starting to wonder if most new cards can now be modified. I made this thread before I knew about doing so.

The links are at the end of the 1st post on the page, they aren't easily seen at first glance.

MSI R9 280x Gamers Edition = voltage locked
Nice too see,
I have Asus 280x both the TOP(R9280X-DC2T-3GD5) and normal(R9280X-DC2-3GD5) editions are both unlocked.

What exactly does underclocking voltage do? I assume increased efficiency at the cost of hashrate.
Will a locked card get less hashrate?

Unlocked voltage means you can lower the voltage (to a degree) with zero loss of hashrate. You save power and create less heat. How low you can go varies even on the same exact model, kind of the luck of the draw. Go to low and the card will crash.
A locked card simply means you have to live with the voltage that the factory has set for a specific speed so you can't lower it to save power.

Thanks for this thread!
So this card can be edited? I'm getting 6 in tomorrow, so I'll be reflashing them.
I'm also getting some PowerColor AXR9 290 4GBD5-MDHG/OC cards in, so I'll check those.

Less voltage , less heat , less electricity bill
