I recently brought a 512 MB RAM (Hynix, 400 MHz), which i installed along my 256 MB RAM(400 MHz) on Asus A7V400-MX board(AMD 2 600XP+, Geforce fx 5500), Ihav been using my system with 256 MB RAM for nearly a year and there were no problems . , but when i installed my 512 MB, 256 was not responding, i.e. the system showed 512 MB RAM, when i removed the 512 and restarted the system it gave long beeps which meant that DRAM was not detected,it was working tilll last day.It seems that my RAM is damaged and i'm quite lucky its in Warranty period.
i want to know whether there are any compatibility issues or any other precautions to be taken when installing RAM.there are 2 slots.anyway i will be installing a 256 later. hlp plzzz
