CMX512-3200C2PRO faulty

Recommended Posts

Been having problems with this computer ever since I puchased this RAM, reboots, lockups, freezes, etc. Occasionally it won't even post. Took it to a qualified Tech shop last week and today they called to tell me the RAM was bad. They said it ran fine with different RAM and so far that has been my experience also. Supposely they tested everything in my PC. I have 2 sticks of the CMX512-3200C2PRO, one is v.2.1, part number: 0428047-0, the other is v.4.1, part number: 0428047-0. My motherboard (1 week old) is an ASUS K8N-E Deluxe. Already talked to the reseller and I can forget about dealing with them again. So I guess I need to see about getting a RMA. Thanks.

I would tend to agree with CMC here :eek: ; with this platform you cannot mix memory and the two modules you have are made with different IC's and would not even post on most MB's when mixed together. Please talk to your reseller and see if they will let you send these back and just get a Twinx1024-3200C2Pro set of modules.

Several weeks ago I did try Memtest and got errors one time, but most times there were no errors but since I don't know much about it (I may have "interpreted" the results wrong and I really don't know anything about RAM anyhow) so I took it to a professional. How they tested, I don't know but I did specifically ask if he tested the RAM and he said yes. RAMGUY-what is "IC's"? Thanks.

I went back to the reseller to do battle again today but I was armed with a printout of my post and your responses. They wanted to argue that the RAM was not dual channel and so the lot and version numbers were irrelevant. Told them I knew it wasn't dual channel and to read the "guru's" replies. LOL I guess after enough whining, complaining, etc. on my part, they took pity on me and refunded my money based on today's pricing (not what I paid :( ). However I was able to purchase a DDR TWINX1024-3200C2PT for less than I was refunded. Cool! Now I just hope it works. If you have any comments or advice (settings, etc., etc.) about this particular RAM and motherboard, please reply here. Thanks for your help.

I see, it's the memory controller (as I said before, I don't know much about it).

 

Long story but to put it short, I purchased the original about 9 months ago however I've been in contact with the reseller off and on most of the time about my problems with getting the new motherboard, new processor and new RAM all set up. They even had it in their shop for a month plus or minus a couple of days (literally). Got the PC back from them in pieces, they left a floppy with PC Doctor on it in the floppy drive, deleted everything on the hard drive, did not reinstall WinXp as they said they would, left a cd containing SP2 for WinXp in my box, etc., etc. (Can be a very long rant. LOL) Anyway it's not exactly like I bought it and out of the blue 9 months later I want to exchange the RAM. (If I ever do this again and have problems, it's going back promptly instead of keep banging my head against the wall trying to get it figured out.)

 

Now for one question, They said to be able to use this RAM as dual channel, I have to put one stick in the 1st slot and the other stick in the 3rd slot leaving the 2nd slot empty. Is that correct? Any other advice as far as settings, etc.? Thanks

Well this is not your resellers fault. And we do sell match module sets just for this type of issue. And we have always suggested you get the memory you plan on using, as trying to match older memorty can be a challange.

Ultimately, yes as the consumer, I am responsible for my purchase. However shouldn't the sales people be informed in their area? I look for the sales person to guide me in my purchase especially when I discuss my potential purchase at length with him/her. It gets to the point do they or do they not want to keep my (and my friends) business? If I hadn't dealt with these folks much I would not feel so strongly about it but I have spent quite a bit of money there over the course of several years plus my lousy experience with their service department. Anyway enough of the rant. LOL

 

Another question is that over the years I have mixed RAM many, many times not only from the same manufacturer but have mixed manufacture brands on the same system and to my knowledge, have not had a problem. Why now? Have I just been lucky or have the systems progressed in technology so much that now it is much more important now to have matched RAM?

After rereading the responses to my post, I feel I need to mention that both sticks were purchased at the same time for this particular motherboard. After my lengthy discussion with the salesman, he was well aware that both sticks were for the same system.

 

Again, any advice as to anything in particular such as settings in the BIOS that I should be aware of? Thanks for your help.
