  1. do you have a memory divider setting? to run at 1600, you need to get it to go to 800mhz in the bios.

    you mean ram multiplier?
  3. no, do you see how in the images, theres a 1067 2:8, that means your RAM is getting to 4x your FSB to get to 1600, you need to get to a better ratio, like a 2:14 or something, i don't know the numbers possible.
  4. could you post a cpu-z screen please ?

    my FSB is 191 by 21x multiplier, thank for your help.
  7. if you want to make sure that you're running stable, you need to run prime95, see if you can get 6 hours out of it without any errors. anytime dude.

    so what ratio i need to put? maybe I will change FSB to 200 and multiplier to 19x with 1066 2:8 ?
  9. well your frequency wont change much, that just changes how much information goes through, you need to worry about your timings, that's what really matters. use everest and check your ram latency, that;s the time it takes for information to be read from the RAM, your latency should be below 30ns which is normal for an i7. make sure no matter what you're at that your prime95 stable, if you're good there, then keep raising that memory divider until you're at the brink of instability because right now, chances are that you're overvolted or undervolted so you need to fix that, you dont want too much or too little power going into your cpu.
