I have a ASUS motherboard. I had 2 sticks of 256MB (Total 512MB) working properly. I got 2 sticks of 512MB and when both of them are installed, the computer beeps 3 times and then starts up but my monitor doesn't come on (the light on the monitor stays amber). I've tried each stick of 512MB individually in the DIMM slots, and each DIMM recognizes each stick with no problems. I've also tried one of the 256MB with the 512MB and the monitor won't come on if the 512MB is in DIMM0 and 256MB in DIMM1; but it will come on and start to boot up showing the 768MB of RAM in the BIOS if the 256MB is in DIMM0 and 512MB in DIMM1, but when it starts to load Windows, it blue screens. All memory scans that I have found tell me that my max memory for this Motherboard is 1GB. I've tried to find firmware for the motherboard and BIOS but have been unable to find anything. My Motherboard is an ASUS A7V-VM v1.02 and my BIOS is Phoenix v2.07 1/19/01. Any help would be greatly appreciated.
