Memory Issue.., Just I couldnt find the solution

[balaG]

I am having a PC with P4 processor,Mercury Board, 512 MB DDR RAM (Single Chip). this was working fine for me for the past 3 years. Suddenly one day there came a no Display issue and when narrowed it, I found the RAM to be the Problem creator. I changed the RAM and the system is working fine.

Just to ensure failure of RAM, I tested that in other PCs

But the Older RAM is working fine on other PCs (Intel D845GVSR Board) and I tested that in other PCs too and that was working fine. Just it Does not work with the Mercury Board. I want a solution to this as this problem looks very strange for me.

I badly need the Solution for this

the RAM perhaps is faulty and your motherboard picks it up right away. In other motherboards it may not. Faulty RAM does not always lead to boot failures. It is only when certain RAM blocks on the chips are accessed that are faulty yield errors. Flakey RAM can be difficult to diagnose without testing.

USE MEMTEST 86+ booted from a floppy to test RAM. Let it run for 7 passes.

It also possible you have a bad memory slot - though unlikely.
