Same way you did the 1.212-> 1.319 voltage increase. Get Afterburner & use the Write & Read I2C interface commands. Use the Titan PCB's Voltage controller datasheet & find out which values correlate to LLC. I don't know how so I cannot tell you, but once you find out which numbers control Vdroop & LLC, you can edit them. Couple people at Guru3d have done it now in the AB thread. I just saw that 1.6 is possible too, although probably requires an ePower, poor man's Pot & Cap mod supplement like FTW420's card. Nvidia's memory voltage should be there as well as long as Vmem is on a programmable controller, so bump the mem voltage for that stable 7ghz+ mem. Realistically only do this stuff with a full waterblock. Be warned
that you will damage your card over time, and increase the risk of frying it instantly, voiding your warranty & losing your 1k investment. The board is only designed with hardware specified to handle those originally intended voltage & current targets. You guys are already way overloading the boards by unlocking that initial voltage step in Precision. Going from the ~1090mv-1170mv range with throttling & boost active to the Engineering bioses with throttling & boost disabled and unlocking the 1200mv range was a big step. Then there is even more danger going from 1200mv to 1212-1250mv range. Now there's chat about 1319-1600mv, and dead cards @1300mv+. At some point the ASIC & mosfets have to give, and if you're disabling over current protection, over voltage protection & throttling & safety mechanisms, then the inevitable will happen.
Guy a few pages back mentions he has 40C core & IRT 85C VRM area. So if you're on air at 70-80C core you're probably well over 120C on your VRMs when using these high voltages. Heat will degrade the chips & increase electromigration, but voltage is what causes the pop. You could turn it on and be dead 2 seconds later without even heating up the card, just from a power spike. OCP/OVP were intended to operate within spec designated by the driver (<1.21). So don't do this at all if you want to avoid Insta-Death, just know it's there and it's possible if you're crazy. Remember GTX590.
I started a thread about software voltage control 5 years ago at Xtremesystems forums before Afterburner & Precision existed. Us newbs without soldering irons used to use Rivatuner & similar commands to edit voltage on 3870's & GTX 280s thanks to a poster named "Just a geek" when Volterra programmable buck controllers came out, petitioned that a "GUI slider" style feature became available to control voltage like core clocks were controlled... a few years later & now there's AB, Trixx, OCguru, Precision, etc & mods like this! haha.
I expect someone is willing .... perhaps CallsignVega or FTW420 will try it out. ;p
