twinn Posted November 21, 2005 Share Posted November 21, 2005 Motherboard: MSI MS-7030 (K8N Neo Series / K8N Neo Platinum) Memory: TWINX CMX512-3200 XMS3200v1.1 400MHz I bought this memory about a year ago when I built my current system, and it has worked great until just recently. I started getting random reboots and hang ups during windows starting up. This degraded into not getting past the post screens. I tried everything I knew of to isolate the problem, updating all drivers, BIOS, etc..but to no avail. Finally, I tried some old modules and was able to boot. I even went as far as to try and determine which Corsair module was bad by trying them alone. The odd thing is that the system works (albeit slower than usual) with each module alone, but will not boot up if they are in the system together. I tried them alone in all 3 motherboard slots to ensure it wasn't a bad mobo slot, but both of them work alone in all 3 slots. I even tried all combinations of the modules together using all 3 slots, but the result was the same: If both of these modules are in the mobo at the same time, it doesn't work. Is this common? If not, I guesss I need to fil out the RMA form and get them replaced. Thanks in advance for any help. Regards, Tim Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted November 22, 2005 Corsair Employee Share Posted November 22, 2005 To properly figure out if the problem is the memory or not, you should run memtest and inform me of the results. Here are the directions you can use to run memtest: 1. Head over to http://www.memtest.org 2. Click on the link labeled "Download (Pre-built & ISOs)" 3. Next click on the link labeled "Download - Pre-Compiled package for Floppy (DOS - Win)" 4. Download the software and Unzip the program files 5. Make sure a floppy disk is inserted 6. Run the program, when it asks which drive letter type in "a:" 7. Program should finish writing, reboot off floppy disk 8. Allow memtest to run 2-3 passes I hope these instructions help you! Please let me know what happens! Link to comment Share on other sites More sharing options...
twinn Posted November 22, 2005 Author Share Posted November 22, 2005 When I boot Memtest with both modules in, it stops as soon as you see the memtest screen with a blinking cursor at the bottom. The system is essentially locked and no user input whatsoever. It displays some basic information, but does not fill in the chipset. If I run memtest with the modules by themselves, they test out OK. I ran 3 passes with each module and there were no errors. After the successful individual tests, I tried both together again and got the same lock up as before.

Corsair Employee RAM GUY Posted November 22, 2005 Corsair Employee Share Posted November 22, 2005 Because the RAM works fine on at a time, this would suggest a motherboard issue as Dual-Channel is a motherboard feature and not on the RAM itself. It could also stem from the memory controller or possibly even be a bad DIMM slot. Your best course of action will be to contact MSI with this issue and see if they can offer any assistance such a replacement or a update to fix this issue.

Corsair Employee RAM GUY Posted November 26, 2005 Corsair Employee Share Posted November 26, 2005 You might check with MSI Tech Support to be sure, but if you have more than two slots I would try the modules in slots 1-3 or 2-3 and see if that helps. In addition, please make sure that you are using the latest version of http://www.memtest.org Link to comment Share on other sites More sharing options...
twinn Posted December 6, 2005 Author Share Posted December 6, 2005 OK, I figured you were right and took your advice on the mobo being the prob. I contacted MSI (not the easiest company to get support from) and eventually ran through some diagnostics that appeared to clear the mobo of any issues. Instead of hopping back on here immediately, I figured I would go ahead and order the parts for the new machine I was building so I could have a brand new mobo and another set of TWINX to test with. I bought a set of Corsair matched XMS3202v5.2 CMX512-23200C2PT to go into a GIGABYTE GA-K8N Pro-SLI. Here arte the results with same exact settings, simply power down and swap modules: New mobo/new RAM - works like a champ New mobo old RAM - fails when ran together (still runs individually) Old mobo/new RAM - works like a champ Old mobo/old RAM - the reason we are reading this thread to begin with. I am on the very latest BIOS (1.9) and have tried all combinations of memory slots, but all with the same result. I understand that the modules test out individually, but it seems pretty clear at this point there is something amiss with these units. Please help.
