    Sounds like you've got it can check w/ CPU-Z in the memory tab, should show the freq as 933 (take that (true freq x 2 to get the effective of 1866) and then ensure timings going down are 9-10-9-27

  3. Hi thanks for the reply but pc still rebooted after 3 hrs timings are showing up as described but not sure about the cpu z and 933 tho
  4. Check CPU-Z (free downloadable program) also go into BIOS and raise the CPU/NB voltage to 1.25

  8. Hi I've downloaded cup-z and dram frequency is 936.5 going up to 940.0 so will i need to change that?
  9. You're right there at 1866 so should be good

  11. Pc still rebooted so I've ordered a new psu thanks
  12. Try raising the DRAM voltage to 1.575
  13. Hi i have installed a new psu because i was getting the event id 41 critical error which rebooted the pc so i disabled the automatic restart function to stop the pc from rebooting which worked but still get the event log error every hr maybe i should of reset cmos first ?
  14. Give it a try
  15. I recently got a 2x8GB kit of Vengeance Pro sticks and I was pulling my hair out for a while. They run perfect and stable at 9-10-9-26 @ 1866MHz on my PC. I kept making sure that the 26 which was auto in XMP Profile1 was 27 and I couldn't get a boot at 1866MHz to save my life.
