TWINX2048RE-3200 and DFI LanParty nF3 250GB


Recommended Posts

I recently purchased a DFI LanParty UT nF3 250GB motherboard and TWINX2048RE-3200 memory to upgrade my system. I chose the memory based on the compatibility chart at http://www.corsairmemory.com. When I inserted the memory and boot the PC I get 1 long beep continuously. I had a stick of XXXXXXXXX KHX3200/512, so I inserted it and the computer came up just fine with no errors.


I did a quick search here and I found this post http://www.houseofhelp.com/forums/showthread.php?t=38536&highlight=dfi+lanparty+nf3+250.


Ignore the RE stuff at the top, it's an error. The list at the bottom is correct.


So... my question is, did I buy the wrong memory?

I agree with Wired. The Socket 754 non-FX AMD Athlon64 processors do not support registered or ECC memory to begin with - but the TWINX2048RE-3200 memory modules are both registered and ECC (note the RE in the product model number). AFAIK only certain AMD Opteron and Intel Xeon systems use or support registered ECC memory. And the earlier AMD Athlon64 FX series processors require registered (but do not support ECC) memory. (Later Athlon64 FX series processors for Socket 939 are designed for unbuffered non-ECC memory, the same memory that most systems use.)


So, for that motherboard, if you want a TWINX2048-3200 or CMX1024-3200 module, I'd recommend the CMX1024-3200 or CMX1024-3200C2 module for an Athlon64 non-FX processor, or a TWINX2048R-3200C2 (CMX1024R-3200C2, currently available in matched pairs only) for an Athlon64 FX51 processor.
