KHX2000C9AD3T1K3/6GX compatible with CMT12GX3M3A2000C9

Hi to all of you there,

I bought a Kingston Hyper X DDR3-2000Mhz 3x2gb 3-4 years ago and i want now to upgrade my pc filling the other 3 empty slots that i have. for some reason the Kingstons now are disappeared even from their website and i can't find them anywhere.

So the only thing that is close to this is the Corsair Dominator XMS3 12GB DDR3 Kit.

I found the pdf on the internet of my existing memory
http://www.valueram.com/datasheets/khx2000c9ad3t1k3_6gx.pdf

and the corsair one

Copied only the 1st DIMM as the other 2 are the same.

So my question is if those 2 will be compatible Running at 2000mhz without having any performance impact or problems.

  1. That's a tough question...

    Yes, the RAM should work. However the size mismatch of the DIMM's could cause the triple channel config to fall out of whack. Also, it is almost never suggested to mix RAM, especially when you are overclocking it, as the stability ramifications can be pretty bad.

    To be completely honest, if you are looking for more RAM, I would just replace the 3 sticks that you have (excellent chips btw) with the kit you are looking at. You will get *no* performance increase by filling in the other 3 slots.

    Hmmm then i need to find a use for my existing memory i don't want to waste them because i paid a lot for them back then! Any ideas?
  3. You can definitely try running them together, and they will probably work just fine, especially at lower clocks. But it is hard to say what will appen after you OC them heavily.

    Ok i will see what i can do cause now i have new problem i am not sure if it will be able to fit in my motherboard. I am 90% that i will have to remove the one part of my Noctua NH-U12P SE2 in order to fit the tall memories... I am sure though my motherboard supports up to 24gb ram.

    Is there any other memory choice you would recommend? or any place i can find the same kingston dimms I would be happy even with 12gb ram.
  5. I tried looking for the Kingston's but nowadays everything is coming in pairs of 2 or 4... The only 3 channel kits are 1333MHz or 1600MHz... :(

    The red fin on the top of the DIMM comes off with a pair of screws, that should cause them to fit under the Noctua.

    Thank you very much m8 i will have in mind your recommendations ;)
  7. Good luck!
  8. Dear Jokerf1

    I have exactly the same motherboard and right now I'm looking to upgrade my memory as well. What was your outcome? I'll be happy if you can share it.
