I'm in a bit of a pickle right now. I upgraded my CPU from an FX-8120 to a FX-9370. I currently have CMZ16GX3M2A1600C10 and it's reading my RAM as 16gb(7.9) usable, and my BIOS reads it as 8176 MB. I've tried each stick individually in DIMM Slot 0 and the computer POST's just fine and I can enter the BIOS, so I put the other stick in to DIMM Slot 2(Dual Channel RAM so I put it in the black slots.) I cannot for the life of me figure out why it can't work as full dual channel so I'm just assuming it's because it's older RAM and it's a newer CPU and a higher-end board. I'm just wondering if this ram: CMZ16GX3M2A1866C9 would be compatible. Also when I look up the product on Amazon, it shows up as CMZ16GX3M2A1866C10. (Note the C9 became C10.) Would that make a difference or should it still work the same?

edit: forgot to include that I'm currently on the most current version of the bios(2201). I've also thoroughly checked for bent pins and there are none. I've also re-seated the CPU.

I'm hoping for an answer to:
1. If it is indeed my RAM at this point causing the issue because it's older.
2. Is the above RAM compatible?
3. Is it fine that Amazon has it listed as C10 and not C9?




 
Solution
Test memory with MemTest86 V7.1 and if any errors replace the entire kit under warranty.

CMZ16GX3M2A1866C9 is also compatible.

C9 and C10 refers to CAS latency where 9 is a faster timing than 10.

I'm not mixing any ram though? If you read my post, you can see I have an issue with my 1600 dual channel ram only reading as 8GB and not 16. I'm also simply asking if the RAM I listed afterwards is compatible with my board/cpu, and if it's still compatible if it's listed as C10 and not C9.
