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?

If there is a docp option, use that. I believe docp is for amd and Xmp is for intel.

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.

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

these are from the original 1866 settings you gave, right after i was forced to go back to bios or load defaults.

The 9-9-9-25 1 settings are running better than I've had since i put the second set in.

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.

Some 8350s can run this, could try 8320 or maybe 8150

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
