der8auer Posted December 29, 2013 Share Posted December 29, 2013 Nvidia GTX Titan reference PCB Pics of the card: Mods: Also, please be aware that the reference VRM design by Nvidia is really weak once you start overclocking. As Rbuass mentioned earlier, his card died at a mere 1.46V Vgpu! If you want to go extreme, you should look into your own zombie vrm. These are the modifications that are on the pictures: GPU (NVVDD) Voltage Measurement GPU (NVVDD) OverCurrent Override GPU (NVVDD) OverVoltage GPU (NVVDD) Coldslow / shutdown GPU Core Clock Range Shift Up Memory (FBVDD/Q) Voltage Measurement Memory (FBVDD/Q) OverVoltage PLL Voltage Measurement Front and back pics (click for high-res version): Okay, here is the BIOS. It's the same like every other extreme overclocker is using but can't share. Basically: - version 80.10.2C.00.00 = engineering bios - version 80.10.2C.00.02 = retail bios With this bios you will have power limit raised to +300%, also for air cooling. Beware ... this is an engineering BIOS for a reason! Link: http://downloads.hwbot.org/downloads/VGABIOS/GK110XOC.rom Quote Link to comment Share on other sites More sharing options...
Massman Posted December 30, 2013 Share Posted December 30, 2013 Tip: use LN2 cooling for PWM. This is how Vivi did it. Quote Link to comment Share on other sites More sharing options...
