CMX4GX3M2A1600C9 - Bad module, settings, or incompatibility?

I purchased a CMX4GX3M2A1600C9 memory kit (2 X 2 GB). Despite running it at 1333 MHz instead of 1600 MHz and the standard memory timings/voltages (1.65 V, 9-9-9-24), and also trying the XMS proifile, I will get random STOP errors in Windows 7 such as the following:

 

 

This was probably caused by the following module: ntoskrnl.exe (nt+0x70740)

Bugcheck code: 0xA (0xFFFFF680003416A8, 0x0, 0x0, 0xFFFFF80002ED52E2)

Error: IRQL_NOT_LESS_OR_EQUAL

 

 

This was probably caused by the following module: ntoskrnl.exe (nt+0x70740)

Bugcheck code: 0x4E (0x2, 0xD8197, 0x21FFFF, 0x1)

Error: PFN_LIST_CORRUPT

 

 

This was probably caused by the following module: win32k.sys (win32k+0x33C9F)

Bugcheck code: 0x1A (0x41289, 0x7AE6001, 0x43A5, 0x72E6045)

Error: MEMORY_MANAGEMENT

 

I am currently using 2 X 2 GB of another brand's (which seems to get censored out) 1600 MHz RAM which works perfectly without STOP errors even though it has more aggressive memory timings by default (8-8-8-24). I know you shouldn't be mixing memory kits - all the crashes I'm describing are with only the Corsair modules installed by themselves. I used the Corsair modules for a span of about 8 weeks and the other RAM for about the same amount of time.

 

My system isn't and hasn't been overclocked at all to this point. Specs are Gigabyte P55A-UD3 rev. 1.0 with newest F11 BIOS, Intel Core i5-750, Windows 7 Pro 64 bit.

 

I have tried Prime95 and Memtest overnight but haven't been able to produce an error. I've sent the kit back to the store where I originally purchased the memory and they couldn't come up with anything either, though I don't know if I trust their testing.

 

Is this more likely to be a problem with a bad module, something in my settings, or it just not liking my motherboard? Before I sent it back to the store I was told by Corsair tech support to consider RMA, but now that the store couldn't find a problem either, is it worthwhile to have Corsair test it out? What would happen if your testing also didn't show any problems, would I just get the RAM sent back to me?

that model ram is not in the i5 compatible page nor is it listed for your board afaik.

Thanks for the reply.

 

It is listed here, 9th in the table for the motherboard (http://www2.corsair.com/configurator/product_results.aspx?id=1330346#other_modules).

 

I can't see the i5 being the problem here, either.

CMX4GX3M2A1600C9 is not listed

It's listed in the 9th row of the table in the link I posted earlier.

 

I also went to the page for the CMX4GX3M2A1600C9 (http://www2.corsair.com/configurator/memory_results.aspx?id=1077551) and the GA-P55A-UD3 is listed under "Below is the list of Motherboards in our system that are compatible with this memory module."

 

I'd be interested in RAM Guy's opinion on this problem.

Looks compatible to me. Corsair would replace the memory automatically.

Lol no worries bro, I just want to get this sorted out...

Bump

 

So should I just request an RMA? Haven't heard back from Corsair tech support again since I tried e-mailing and calling them.
