The Gen3 > does not allow setting of fixed GPU voltage (only offset) I _think_ I've solved the problem - SDRAM Voltage The SDRAM I am using has a rated operating voltage of 1.5V +/- 0.075. It looked like the motherboard BIOS had decided to use the upper limit of 1.575V when set to 'Auto'. I changed it to 'Manual' and set the SDRAM voltage to 1.5V and it's been running stably for the longest time it ever has.
