2x G.SKILL Sniper Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 14900) F3-14900CL9D-8GBSR on GIGABYTE GA-990FXA-UD3

I had the first 8 gig set running fantastically at 1866 along with my FX-6350, and decided to order a second set. After installing and checking the XMP settings in bios i restarted and my computer failed to boot. It's currently running at 1600 but is very sluggish. What can i do to run the full set at 1866?

  1. If there is a docp option, use that. I believe docp is for amd and Xmp is for intel.
  2. Best answer
    To be honest might not be able to, many of the 6350s can't even run 1866 and the FXs are 'rated' only up to 2 sticks of 1866

    Think I'd try at 1600, 9-9-9-25, 2T or 2N, 1.5 if good there up to 1866, 9-9-9-27, 2T or 2N, DRAM voltage at 1.55 and raise CPU/NB to about 1.25
  3. Thank you very much for the quick replies :) i will try these out when i get finished with my current match.
  4. Drop an update and let us know ;)
  5. will do, thanks bud.
  6. i got it to boot with the 1600 settings, however it is a bit slower than before i changed the settings. I also attempted to boot the 1866 settings and could not.
  7. At 1600 could try changeing the CR to 1T or 1N (should be at 2) with things as is or drop CL to 8 i.e. instead of 9-9-9 go 8-9-9 initially
  8. i have a bunch of pics of my bios screens with the info i had there if that may help at all.
  9. Would, Yes
  10. these are from the original 1866 settings you gave, right after i was forced to go back to bios or load defaults.
  11. The 9-9-9-25 1 settings are running better than I've had since i put the second set in.
  12. In you first pick are showing DRAM voltage as 1.154 it should be 1.5 or 1.55
  13. oh lawdy, let me adjust that.
  14. failed again on the 1866, i booted with optimized defaults and its running alright now. Is there another processor i can pop in here to handle this, or is this the best i can do for now? Thanks again for all the help.
  15. Some 8350s can run this, could try 8320 or maybe 8150
  16. It may also be that the two kits do not match well enough to operate at the high speed of DDR3-1866. This is why we must produce 16GB kits that are pre-matched, tested, and guaranteed from factory to work in a single system.

    Thank you
