Official R9 Graphics Card Voltage Locked/Unlocked list

[Gazza1]

Post the cards you know for a fact are voltage locked and voltage unlocked.  Either confirmed from your own testing, or from what someone else has shown you as a fact.  

You may all post and I will update this main post every so often with your results until the list is complete.

Any R9 graphics card is fine.  If you want to include last year's 7000 series we can do that too.

I'll start with a couple on the list are confirmed personally by me.

Unlocked:
290  Gigabyte R9-290 1.047 (AB 13.17 beta)    845kh/s
290  XFX R9-290A      1.047 (AB 13.17 beta)    845kh/s
280x Sapphire OC 100363BF4L,
280x Asus R9280X-DC2T-3GD5, R9280X-DC2-3GD5
280x XFX all
280x MSI Gamers Edition
290x XFX ENFC 835Kh/s @ 860/1250 -25mV
270 Asus 1.100/1030/1400 = 440 kh 7 days stable.  120 W draw per card

-----------------------------------------------------------------------------

7970 MSI 7970L/BE 755KH/s @ 1080/1500 1.119mV
7970 MSI 7970L 606-V278 645KH/s @ 840/1600 1.056mV
7970 Sapphire OC 100351SR,
7950 Sapphire OC 100352-3L,
7950 MSI TF3GD5/OCBE
7990 MSI 6GD5

-----------------------------------------------------------------------------

Locked within software but VBE7 BIOS moddable:
280x Sapphire Toxic 100363TXSR
280x Gigabyte GV-R928XOC-3GD  1.09/1025/1500     725kh/s
270 Gigabyte at 1.043V and hashing at 475 Kh/s and 445 Kh/s
-----------------------------------------------------------------------------
7950 Gigabyte GV-R795WF3-3GD  1.09/1133/1250     700kh/s
7970 VTX3D X-edition

--I'm starting to wonder if most new cards can now be modified thanks to VBE7


Here are links to VBE7 & more instructions (download is at the first link in the bottom of the first post)
To the guys who made VBE7 "Darkhmz, DroiDMester, & whoever else"; you guys rule and many thanks

Locked but BIOS moddable: vtx3d 7970 X-edition

[Gazza1]

Thanks

[symzzi]

MSI R7950-TF3GD5/OCBE unlocked

MSI R7990-6GD5 voltage unlocked using afterburner beta 13.11

[surivrox]

SAPPHIRE RADEON R9 280X OC (11221-00-25G)
ASUS R9 280X (R9280X-DC2T-3GD5)
Club3D Radeon R9 280X 3GB RoyalKing CoolStream (CGAX-R928X7O)

Anyone?

[DrJimmy]

The Sapphire Toxic 280x can be bios modified to lower the voltage.

[Quix]

Club3D Radeon R9 280X 3GB RoyalQueen CoolStream - Unlocked

Personal experience, I have a couple of these.

What exactly does underclocking voltage do? I assume increased efficiency at the cost of hashrate.

Will a locked card get less hashrate?

[logicus]

Unlocked:
Gigabyte R9-290 1.047 (AB 13.17 beta)    845kh/s
XFX R9-290A      1.047 (AB 13.17 beta)    845kh/s

Locked but VBE7 BIOS moddable:
Gigabyte GV-R795WF3-3GD     1.09/1133/1250     700kh/s
280x Gigabyte GV-R928XOC-3GD  1.09/1025/1500     725kh/s
Confirmed personally by me (my rigs)


Most of 7950,7970 and 280X are VBE7 BIOS moddable

Less voltage , less heat , less electricity bill

[crazyates]

Thanks for this thread!

Locked:
280x Gigabyte GV-R928XOC-3GD

Locked within software but VBE7 BIOS moddable:
280x Gigabyte GV-R928XOC-3GD  1.09/1025/1500     725kh/s

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.

Cheers guys

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.

Nice too see,
I have Asus 280x both the TOP(R9280X-DC2T-3GD5) and normal(R9280X-DC2-3GD5) editions are both unlocked.

[Friesje]

MSI R9 280x Gamers Edition = voltage locked

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.

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.

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