LM324 (so L385 on yours ?) is one he ended up having to mod to get more volts to memory.

BTW there is a lot of volts flying about the card where you have measured, your core should only be 1.2v not 1.3v default so the points may not be the volts getting to core, ram needs 2v but until I get correct point to get true reading I wont know why it cant do 800/1600ddr stock, Im told its probably low like 1.7v or such.
