Intermittantly the post memory chk will lock the system. Sometimes on cold boot but more often on warm boot. This is the first time i have tried using edo memory so I'm not sure if I am using wrong CMOS setting for EDO. I have Award BIOS. I usually use non parity and set dram ECC/Parity to ECC. and Memory Parity/ECC check to Auto. Or do I just have bad simms. I hate to spend more money on simms to find out. Any suggestions? ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
