I have an ASUS STRIX 970 that I have been overclocking.

Basically what I have done so far is test the memory speeds extensively using Precision X, and once I have settled on a stable, solid overclock, I go into the Maxwell II Bios Tweaker and apply these settings as the new default clocks.

I also raised the TDP such that 100% is at 225W (based on 75W from the slot and 150W from the connector).

And finally, I changed the fans so that they spin up closer to 45C or 50C, and max out at 75C, rather than waiting until 60C to start doing anything. (That cooler pumps out heat like it's nobody's business.

My ultimate goal is achieve my stable overclocks in the BIOS alone, without the need for any software-based modifications. I don't like the idea that my fan speeds, voltages, or clocks must rely on (often crash-prone) software. I've already had precision X keep my fans off under load.

My problem currently has to do with the core. The core overclocking is quite confusing between the basic clock settings, the voltage table, and the boost table. I can't simply add 200MHz (my stable speed, which tended around 1555MHz) and have it work. It normally doesn't try to reach the full 1.212v, or if it does, it doesn't reach the full boost speed. So sometimes I will try to increase the clock, and the clock will actually LOWER and/or my voltage would drop to something like 1.07v.

Do you guys have any good guides or tips for BIOS modding?
