Abit NF-M2S Motherboard Memory Problem

[thomastt37]

I have an Abit NF-M2S Motherboard with AMD Athlon 3800+ Duel Core 64bit processor.I previously had 2 x 1GB DDR OCZ PC5400 memory modules installed until 1 module failed and the PC wouldn't  POST until I removed the faulty module.I have tried without success replacing the failed OCZ module with a Kingston module[known working] of the same value but the PC wont POST and gives Long Continuous BEEPS until I remove it.With one module it will boot ok  in either of the two slots but not with two installed..Any ideas?

The Kingston is probably incompatible with the OCZ stick...different memory timings.
You should get an OCZ match...
