Ram Compatability Question.

Hello, I am relatively new to this memory thing as I have built a new rig recently. I first purchased Corsair 4GB (2X2GB) @ 1600Mhz.

Recently, Newegg had 8GB (2x4GB) @ 1333Mhz ram on sale and I purchased that.

Will I have any speed, timing conflicts, or voltage issues if I run it all together?

Thanks in advance.

  1. You might get them running together but I'm skeptical. There is a speed conflict, a voltage conflict, and possibly a timing conflict.

    You would be better off selling one or both kits and (if you sell one kit) run the left over kit (if you sell both kits) buy a new 8GB kit.

    Memory can be the most fickle component and mix-matching kits is likely to work with seemingly identical kits, but with very different kits like yours there is probably no way it will work.

    You can try them together but don't get your hopes up.
  2. I just tried running it together and my computer is detecting 12 GB of RAM. But once again, I am afraid of crashes due to speed, timing conflicts or voltage issues? How do I know if all my ram is in sync with regards to speed, timing conflicts or voltage?
  3. Best answer
    If it runs then the voltage, clock rate, and timings are automatically in sync. You should run a heavy benchmark to test for stability. Try running PCmark and/or Sandra. If you don't BSOD or have some sort of error/crash then you should be fine.

  5. I decided to run memtest for 5 hrs and went through 4 passes. I am going to assume everything is okay thus far since crashes and errors arent popping up left and right. But I guess I will run memtest in the future for 12+ hrs just to make sure. Thanks for the replies everybody!
