CMX4GX3M2A1600C9 listed as CM3X2G1333C9

I bought the CMX4GX3M2A1600C9 4 gigabyte kit (2x2GB) from Newegg.com. I've been having issues with random BSODs and "memory can cannot be written" errors with Windows 7 64 bit since I built the computer about a month ago. I was was running at 800MHz. While troubleshooting I lowered the DRAM speed to 666MHz, and the system become completely stable. While trying to figure out the problem, I ran CPUID CPU-Z. On the Memory SPD tab, Slot#1 shows the memory part number as CMX4GX3M2A1600C9, with the JEDEC frequencies at 440MHz, 592MHz, 666MHz, and 800MHz. This looks correct to me. However, Slot#2 shows the part number as CM3X2G1333C9, whith JEDEC frequencies at 444MHz, 518MHz, 592Mhz, and 666MHz.Both modules look the same; both are labeled as CMX4GX3M2A1600C9.

 

Is this just a SPD profile problem. I manually set the module that comes up as CM3X2G1333C9 to the same as the 800MHZ XMP profile of the CMX4GX3M2A1600C9 labeled one. Seems to be stable now.

 

Do I just keep the 1333MHz one with manual timings, or is it it better to just RMA it?

 

Anyone know the complete recommened memory timing table for the CMX4GX3M2A1600C9?

Lets go ahead and replace the kit.

Do I have to send in both modules, or can I just send in the bad one? Sending in both modules would mean no computer for a week or more.

 

I was going to just keep the 1333MHz one, as it was stable with manually entered XMP speed timings. Until today that is. I couldn't even use Windows for 5 minutes before blue screening. Wasn't even stable at 1333MHz.

Send the whole kit so you know you'll get a matched kit back. After you get an RMA contact customerservice@corsair.com and ask about an advanced RMA.
