Bad cmx512-3200c2


Recommended Posts

I purchased two sticks of the above mentioned memory from newegg.com and I am having problems installing windows xp on my machine that uses the memory. If I use the first stick I purchased then everything is fine. If I use the other or both then I get errors and my computer crashes half way through instalation.The hardware for the system is as follows:

 

Abit AI7

p4 3.0

WD 160 & 80

lite on dvd burner

lite on cd burner

radeon 9800 all-in-wonder

Bad Stick:

 

Part #:CMX512-3200C2

Lot #:v5.1

Version #:0452078-0

 

Good Stick:

 

Part #:CMX512-3200C2

Lot #:0503070-0

Version #:v1.2

 

The only settings I have changed is the input voltage to 2.8. I haven't messed with the timing bc I dont know how and the processor is running stock at 3.0 ghz w/o oc.

I am sorry but you should not mix modules. Please test them one at a time and lets make sure one is not failing, but we do not have any way to make 2 modules that are not matched work together.

What do you mean? I bought them both frome the same place at different times and I shouldnt have? If I want to fill all 4 of my systems slots I should buy all 4 memory sticks at once? Am I not allowed to expand?

I have tested these sticks individually and only one fails.

MB's are pickier with memory than they used to be and with AMD 64 especially since the memory controller in the CPU; all of the modules would need to be exactly matched. Sorry. But this is a limitation with in the memory controller's used in the MB made today. You can add memory later but you would need to match the modules you have now in both part# and revision for best performance.

It would be the same issue, but with Intel platform you can some times make it work by manually setting the timings and you should not run them in dual channel. I would suggest Cass 2.5-3-3-7 and set the Dim Voltage to 2.7x Volts, and you will need to manually set the memory frequency at DDR400 as well.
