steven975 Posted December 19, 2005 Share Posted December 19, 2005 I have 2 Corsair modules, both CMX512-3200C2, one is V3.1 the other is V1.1. While I realize these are not matched, they have always worked in dual channel in my MSI K7N2 Delta2 motherboard in this fashion (I would guess since the Nforce2 is 2 independent channels vs true 128bit like Athlon64s??). Now, however, the system started flaking out, crashing on boot or in games. I have diagnosed one of the modules as the cause, specifically the V1.1 module. Using ONLY this module, the system is unstable. Also, it will not boot up on the SPD or AUTO settings; I have to use the V3.1 DIMM, set some manual (not too aggressive...2.5,3,3,8) settings in the BIOS, and restart the machine after swapping the 2 modules (while OFF of course). When I do use the system with only this module, it crashes quickly. I've tried down-clocking to 166 or 133Mhz...still the same result. The V3.1 works fine by itself, though. I ran Memtest86 with both modules and it passed 5 times with no errors. Still, something is up with this 1.1 module as it worked fine before and now does not. Also, the 1.1 module does not work at all in my K8N Neo2 Platinum, either. I realize this is a dual channel board, but the system will not POST with the V1.1 module, even if it is by itself in single channel mode. The V3.1 works fine. I've tried upping the voltage to 2.8V and the 1.1 module still won't work right. So, does it sound like the module is defective? I've tried turning off agp fast writes, turning on spread spectrum, upping CPU voltage and none of these help. Link to comment Share on other sites More sharing options...
