Hello guys, I'm trying to mod my MSI GTX680 Lightning vBIOS using Kepler Bios Tweaker 1.27 After extensive testing, I found out that my card capability in MSI Afterburner is as follows: +61mV on core +50mV on vram Max power limit +140 on core +500 on vram These settings ingame would effectively be: Around 70%-75% power limit 1346mhz core 7000mhz vram 1.256v boost final voltage These are rock solid settings in games like BF4 and GTA V and I'm happy with the performance. My original vbios is the unlocked LN2 VBIOS that has stock all power limits to 600watt on 100%. So i did not tweak power table when modding the bios, it's quite enough for what I'm doing. Now I'm doing everything in KBT 1.27 and doing voltage table as much as 1.26v in the boost clocks(I increased all the clock table voltages sliders above 1110 mhz to around 1.25v) then I flashed the bios but ingame and at 1346mhz it only reaches 1.205v and then crash to desktop. Any help on that? And why msi AB ups the voltage to desired levels but tweaking the bios voltage does not? I'm using last WHQL 361.75 on Win 10 pro 64bit Thanks
Anyone? I hear that reference 680s (or at least reference PCB) have hardware limit for voltage of 1.212v. But the thing here is that MSI AB does raise the voltage to 1.285v if I set +100mv in it(not that I want to use this high voltage but it does if I set it). But my 680 is MSI Lightning one with unlocked bios with no restrictions. Thanks
