Hello everyone, I have had this card for a couple years now and have been trying to unlock voltage control since I purchased it when it was $499 at Newegg. I finally found a solution. The Asus GPUTweak 2.2.1.4 option does not work... All HW monitor programs never read over 1.170v with any overclocking software. GPUTweak (all versions) never read anything over 1.084v. Now that has all changed.
I found out that the Asus ROG MATRIX-R9280X-P-3GD5 has the same video out layout as my HD7970-dc2-3gd5. Furthermore, all R9 200 series cards are essentially the same as the HD 7000 series as we all already know.
So I flashed this bios "http://www.techpowerup.com/vgabios/149810/asus-r9280x-3072-130827-3.html", with the latest AtiFlash on a bootable USB flash drive : . Now My idle Temps have lowered from 40c to 34c average. It can reach 1130mhz core and 1650mhz mem without hitting over 66c or displaying artifacts in the Valley Benchmark 1.0 on the Extreme HD preset.
With the HD7970 original bios, clocked at 1040/1500 the card was hitting 70c in Valley 1.0, and would display artifacts at 1090mhz.... It will go higher but I need better cooling to achieve stability when going much over my current overclock (displayed in the posted image)
The second image is proof that GPUTweak reads that the voltage is above the 1.170v limit that these cards have.
Also GPUZ reads 1.256v
[edit] so thanks to Dave(cadaveca) I have learned that this only seem's to work for version 1.00 cards, I am posting another pic of My cards PCB with the backplate off showing the revision number.
I hope this helps someone to unlock their voltage on a ASUS HD7970 DC2 3GD5. Rev. 1.00x
