Really need help underclocking ram


Ive got a motherboard thats not set up to run 1600mhz ram, and am running 6gb of DDR3 G.Skill 1600mhz on a Gigabyte X58A-UD3R.....

I need someone to tell me what I need to change in the bios in order to get the ram running at 1333... Sorry for being a noob..... but this is a newly built pc and ive been having problems with it randomly blue screening and restarting from time to time... and I feel like this is probably why.

More about really underclocking
  1. Why do you think your motherboard does not support 1600MHz RAM? Quote from Gigabytes website "Support for DDR3 2200/1333/1066/800 MHz memory modules" and here they list memory support

    Have you set your RAM voltages to what they are specced at? It may be different than default.
  2. I say this because they dont list "1600" as an option for what it supports and thats what ram is in it?
  3. Also, the voltage is correct, 1.5.... and in the bios, it say's the memory speed is running at 1066... but on CPU Z, it say's its at triple chan. and running at 539.7... I may be a retard and be doing this wrong, but dont you multiply that by 3? 1619.1
  4. first, channels don't multiply the memory speed.

    you have to multiply waht you see on cpuz by 2. 539.7*2= 1079.4, to get the actual speed. so it's already underclocked. and shouldn't be unstable.

    try swapping the sticks to some other memory slots, and try different combinations.

    also give us the part number of the memory so we can see the specs
  5. You say that they don't list 1600MHz modules but yes they do on the memory support list I provided. Also as above said you don't multiply the speed by the channels, since is DOUBLE data rate (DDR) it is equivalent to twice the speed.

    Run Memtest86 to check for RAM errors.
