Ram Problem: Transcend 1GB Stick vs Xion 1GB Stick.

[GauravCJ]

My friend has a motherboard with two DIMM slots. On one, he has a 1GB Transcend DDR2 667MHz single stick ram, the other is empty.

Today we went out and bought another 1GB stick, but not of the same company. It's from ZION, and it is a single stick 1GB DDR2 667MHz ram as well, so both of them are similar.

The problem is, the system boots with only one of them. If I put both into the two DIMM slots, then the system won't boot. If only one of them is put into ANY of the DIMM slots, the system boots fine. In other words, the two sticks are refusing to co-exist.

What could be the problem? Timings and CAS Latencies? Isn't RAM of same type (DDR2) and same frequency (667MHz) supposed to work with each other seamlessly?

It should, let him check again

Checked again. Just won't boot with both, but only ONE of them. What could be the problem?

what about the slots putting only one and anyone in any slot works.
Or only one slot works. or only one of the 2 sticks work.

Both sticks work perfectly fine INDIVIDUALLY.
Both slots work fine.
