Title: Official R9 Graphics Card Voltage Locked/Unlocked list Post by: Gazza1 on January 03, 2014, 03:23:48 AM 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. Quote 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: ----------------------------------------------------------------------------- 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 8) ;D http://www.techpowerup.com/forums/threads/vbe7-vbios-editor-for-radeon-hd-7000-series-cards.189089/ http://rumorscity.com/2013/12/09/how-to-modify-video-bios-to-undervolt-gpu-in-linux/ ------ ;D 8) Title: Re: Official R9 Graphics Card Voltage Locked/Unlocked list Post by: Wipeout2097 on January 03, 2014, 03:56:46 AM Locked but BIOS moddable: vtx3d 7970 X-edition

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.

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.

Title: Re: Official R9 Graphics Card Voltage Locked/Unlocked list Post by: jhk753 on January 18, 2014, 12:12:07 AM Same question here for R9 290.
Plus I'm in linux and CGminer doesn't show voltage on my card. But if I try to change the voltage, it says that driver accepted but doesn't show any change on cgminer outputs. I'm not near my rig so I can't check the wall plug, but what do you think it means ? Is CGminer capable of undervolting in Linux with latest beta driver ? Title: Re: Official R9 Graphics Card Voltage Locked/Unlocked list Post by: codon on January 23, 2014, 03:16:09 AM No one has mentioned the 270's yet. Here's my experience:

Unfortunately the amd drivers in linux don't allow you to modify the voltages through software. BUT there is a guide linked in the main post that makes it pretty easy to do the undervolting via modifying the card's bios.

I might try dropping the voltage further, but pretty happy with the results at 1.1v also my whole system was only drawing ~525w running windows off an SSD, might be lower now that i'm running linux bamt 1.3 off a USB 3.0 drive. My PSU is a Corsair AX860i, mobo is asus M5A99X Evo R2.0 with a Sempron 145 CPU. the hardware comparison guide says they only draw 253w eac, and that's about what i'm seeing, not sure what's up with your system.

Although it would appear that using VBE7 and atiflash looks like it changes the voltage (shows in GPU-Z and in cgminer as new lower voltage), If measured on the card you will find no change. This is true for card versions 3SB and above (2SB cards can be modified in this way). The only voltage that does work is 0.943 V (Dont ask me why?). The only drawback with this voltage is that you wont be able to hash anywhere near 700K you might get 650K at best. So until MSI release an editable BIOS (if ever) or another tool is created that can edit it we are stuffed! I have 3 X 3SB cards and 1 X 2SB card.
