Hi Everyone, Just read the whole thread, amazed at how helpful everyone has been. I have the XFX R797G-TDFC DD Card and have a custom water cooling loop. Currently VDDC runs @ 1.188mv under load and I have the memory voltage MVDDC set to 1688 mv using modified Trixx V4.4.0. Using Trixx I can set the mvddc all the way up to 1800mv but the memory voltage won't actually go above 1688mv. I mine litecoins raising the mvddc from stock of 1500 up to 1688 allows me to increase the memory from 1700 MHz up to 2025 MHz which yields me an additional 130 Khps. the problem: In Linux (Ubuntu 13.04) I cannot increase the MVDDC so I've had to resort back to Windows
My understanding from reading this thread is no one has really figured out how to change the mvddc through the bios, is this correct? I figured where I'm increasing the mvddc voltage the card would probably run up against maxium TDP theoretically 300 watts @ +20% power tune so I found the powertune section and replaced the number "14" with "32", if I flash this bios back to the card will I immediately have ability to increase powertune up to 50% now using Trixx or CCC?
would be nice to have a totally unlocked card but from what I understand that's not possible?
Can someone please modify the 3D performance to stock clock of 1250 core @ 1.3V, (if like the 7950 tdfc the vddc cannot go above 1.25v please do that) with a memory speed of 1600 MHz and the 50% powertune option.
my asic score is 64.3%
I have attached the original non modified my the hex noob bios
