[req] Quadro K6000 reported memory size change
JBDynamics replied to alex870's topic in NVIDIA Video Cards
I just acquired a P2803 reference spec eVGA GTX 780 Ti, and I soldered a Vishay Dale CRCW120618KOFKEA resistor between the VCC and SCLK pins on the EEPROM to change the device ID from 100A to 103A. I am now in the process of pinpointing the opcode in Quadro K6000 BIOS that sets the VRAM to 8GB. By doing a 3-way binary comparison of the GTX 780 Ti BIOS against the K6000 BIOS against the Noveua BIOS, I believe I can narrow down the list of opcodes that might set the VRAM significantly, and once I have the list, its just a trial and error process. Once I am able to get the K6000 BIOS to report 3GB of VRAM when flashed to the GTX 780 Ti (Dev ID 103A), I will post that modified K6000 firmware here.
