details of system unit:

Sempron 3100+
Asus K8V-VM
256Mb X 2 DDR 0400 CPAQ
512 7800 gt Inno3d
Windows XP SP2

Situation

I want upgrade my RAM from 512 Mb to 1 gb. but everytime i put two 512 Mb on dimm slots(1 and 2) they dont perform POST and no display on the monitor but everything is powered on CPU,DVD player,Fans etc..So i tested both rams on dimm1 slot and they look good. They perform POST and starts on windows.After testing on dimm1 slot i test it on dimm2 slot..both RAM dont works on dimm2 slot. So i come up with conclusion that my dimm2 slot is defective..But suprissingly when i put the older RAM(256 Mb) it works on dimm2.It Perform POST and Starts windows..What do you think is the problem on RAM or in MOBO?or theres something that i need to configure to BIOS?

Pls help me on my problem?God Bless!

This is a common problem especially on older systems.

It is that your two stick of ram don't like to work together or just don't like the chipset of your mobo. Getting a different brand of ram may fix the problem, but it may not. You may have to go through quite a few different sets of ram to find some that work.

In your case, i would just run the 512 in slot 1 and the 256 in slot 2. You should have a minimum or 1gig (as you are trying for) on an xp system that you game on. But unless you know someone with a bunch of sticks of ram lying around that you can try, or can buy ram and return it, you may be stuck with what you have.

So, yes in a sense it is your mobo, though your mobo isn't broken, it is just too picky.

EDIT:
Also, the pc100 is more picky then if you have pc133. Same ram, but a newer updated version that works better with more mobo's.

you can, but the memory will only be run in single channel mode... although given the age of the parts you're talking about the system may be only capible of single channel anyway.

is non ECC are the so called generic RAM?

Most generic RAM is non-ECC but generic doesn't necessarialy mean that its non-ECC...

When you see ECC think "server memory" and non-ECC think "desktop memory" thats all.
