I remember being able to run a custom bios and run 1.281 vcore with no issues up until driver 385-389 somewhere in that time frame. Now I am stuck on factory bios and only 1.22 Vcore.
I have tried installing several of the bios from the OP but none seem to work. Either they boot into W10 but have stock voltage or simply don't work.
I have modified the bios I used to use with the settings provided by looniam just a few posts up, yet still stuck on factory voltages. I was able to modify my factory bios and up the power limit but that is it. Still stuck on stock voltages.
As it sits right now, I run both my TXMs on my tweaked power limit bios using Afterburner at +112 mV, 133% power limit, +115 core and +500 memory which results in 1481 Mhz core and 2003 Mhz memory. With my previous bios I could run 1553 Mhz core with no issues at all.
So, can you still modify voltages with custom bios and use new drivers or am I stuck using old drivers with custom bios or new drivers on factory tweaked bios?
