Old Skooler Posted June 24, 2005 Share Posted June 24, 2005 Module Part Number: CMX512R-3200C2 I have an intermittent problem. Sometimes when I boot, POST shows 512MB, other times it wil show 1024MB. I have TwinX XMS ECC memory (for Athlon 64 FX-51, but I need it for my dual Opteron board). I've tested both modules in each of my DIMM slots, but the problem arises in random slots, so it can't be my motherboard (besides, it's a brand new Asus K8N-DL). I tried contacting the reseller where I bought the pair a while a back, but they seem to be out of business, (or maybe they have a new site I don't know about?) What should I do?

Corsair Employees RAM GUY Posted June 24, 2005 Corsair Employees Share Posted June 24, 2005 I would suggest you get both modules replaced so they match. Please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it! Link to comment Share on other sites More sharing options...

Old Skooler Posted June 25, 2005 Author Share Posted June 25, 2005 Question about registered TwinX XMS Memory (for Athlon 64 FX) Module Part Number: CMX512R-3200C2 I realize this may not be the right section probably, but it is still regarding the warranty on the same modules I started this post for: I got to thinking the other day ... I understand this memory was designed specifically for the AMD Athlon 64 FX series because the first incarnations required registered memory in Socket 940 form. Now that AMD has moved the FX series to Socket 939 to shed the dependency on registered memory, what does the future hold for this specific module? Will Corsair discontinue this module? If that should happen, how will the lifetime warranty be honored? Will I be able to buy additional pairs in the future? Also, what other capacities are TwinX XMS ECC modules available in (or just the dual 512MB pairs)? (Thank you for bearing with all my annoying questions!)

Other boards / CPUs can use that memory, so no worries. Other memory has been discontinued over the past, and they just replace them with something of equal or greater performance from what I've seen.

Old Skooler Posted June 25, 2005 Author Share Posted June 25, 2005 I *KNEW* I had seen a table somewhere on the site showing other Registered XMS Modules. Thanks for pointing me in the right direction. What's the difference between modules with "RE-3200LL" and those with "R-3200C2"? I think I understand that "R" means "registered", "LL" means Low Latency, and "C2" means "CAS2". I just don't know what "RE" means, and while I do know what CAS means, what does Corsair mean by "C2"? Also... could I install any combination of registered XMS modules on a single motherboard? ... Or are only some of theese modules compatible with what I already am using? Thanks again!

Corsair Employees RAM GUY Posted June 27, 2005 Corsair Employees Share Posted June 27, 2005 Please see What does C2, LL, PT, R or RE stand for in the part#? Link to comment Share on other sites More sharing options...
Old Skooler Posted June 27, 2005 Author Share Posted June 27, 2005 Ahh, I see. I thought ECC and registered were one in the same. So not all registered DIMMs have Error Correction Code then. Will A Socket 940 CPU accept both? R = Registered RE = Registered ECC Thanks again! Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted June 27, 2005 Corsair Employees Share Posted June 27, 2005 Socket 940 needs registered memory only Socket 754/939 both need unbuffered memory Link to comment Share on other sites More sharing options...
Old Skooler Posted June 28, 2005 Author Share Posted June 28, 2005 I want to thank you for all your answers thus far, I think I *almost* have this all figured out... If I wanted to buy more memory to fill all 6 of my DIMM locations, would I need to get the exact same TwinX pairs (pn: CMX512R-3200C2) for compatibility with the pair I already own? ... Or could I mix R = Registered and RE = Registered ECC modules? ... Also can I mix TWINX and CMX? ->>Tom Link to comment Share on other sites More sharing options...
Wired Posted June 28, 2005 Share Posted June 28, 2005 1. That picture says REGISTERED ECC, so I'd go with RE memory. 2. TwinX is the name for a kit of 2 CMX sticks tested together. What, exactly, is TWINX? 3. TwinX pairs are only guaranteed at their timings with one pair. So if you run more than one TwinX pair, the timings aren't guaranteed. All memory should be the same part # AND revision #. How To Read the Memory Label Link to comment Share on other sites More sharing options...
