I have just built new system with GA-MA785GM-US2H motherboard. Systems posts with one memory module installed in DDR-1. With two memory modules installed in DDR-1 and DDR-2, post fails with continuous long beeps. Changed the memory voltage from 1.8 to 1.9 and 2.0; same result.
Memory modules are both good, as either one works by itself in DDR-1. They cane from another system (FoxConn), where they were configured and working at 2x2gb dual channel. Memory is Corsair CM2X2048-6400C5, 1.80V ver 4.2.
Read a similar thread here where the Gigabyte was RMAed for a different brand motherboard. Is there any way to get this 4GB running dual channel on this motherboard?
