Bad CMX512-3200C2PT Module


Recommended Posts

I have an ASUS A7N8X mbi and I am using an Athlon 2500+ Barton CPU with a single CMX512-3200C2PT module.


During post the voice reporter tells me that the memory test failed. I am also having some system instability.


If I set the memory auto by SPD it sets it to 2.5-3-3-8 which is not what I read is the optimal setting for that module. I changed my BIOS to run it at 200Mhz and 2.5-3-3-6 and if anything it is more unstable.


The memory Serial # is 20145420.001256.


Will you give me an RMA?
