I have an ECS P4M800PRO-M3 mobo and I have the latest BIOS. It doesn't detect my RAM memory. Actually I have 2 RAMs and 1 is Kingston value ram 512mb 533 and the other one is PQI 1gb 533. The kingston ram came with my PC and it was working properly until I decided to upgrade it with the 1gb. Now only the 1 gb is working. I tried swapping the RAM and also running them alone. Both are working flawlessly when alone but the problem comes when I use them both. Is there any way to detect both of my RAMs.
