text: Corsair Vengeance 2x 4GB sticks and Asus Motherboard - Page 2 - Windows 7 Help Forums
  Ok.... tried with the RAM suggested settings again (properly saved this time 9-9-9-24 at 1.5 volts, 1333 ghz). I tried a reccomended overclock 1.65v 1600 mhz, 9-10-9-27. I additionally tooled around with it a bit myself and tried several various settings. None of them fixed the issue.
  I also tried the F5 during BIOS setup saved and restarted, did not fix issue.
  I am doing testing now with a USB boot. 50% through 0 errors thus far, will update at end. (and no im not doing something silly that isnt what you suggested while using the cpu.... im on my laptop!)
  Testing finished, no errors.... RAM is fine. Waiting for more ideas if there are any, if not I think its time to call it match win- CPU and get a different MOBO.
  Here is the qualified venders list for your mobo for Corsair 1600 ram. the list can be found here.
  It dosen't mean that these are the only modules that will work, only the only models they tested. But, it is a guide to go by. I don't know the exact model you have.
  I must admit , I am a little stumped as to why the bios is not saving.
  When I do a bit of extreme overclocking, if I save the settings and it fails to boot due to me be a bit over the top with the settings then the bios will not save the settings and just boot with the default values.
  Its almost as if the default values for yours are wrong so it just fails to boot into windows every time.
  Tottaly right in order to use 1600mhz you have to up the cpu and do a few changes mind you i did some research before i oc'ed my rig
