help HELP!! RAM speed issue

[LOANSHARK]

HELP PLEASE!! 

OK so my system 16gb ddr3 kingston hyperX 2133 RAM, however windows crashes at 2133 but is stable at 1866. Today however I was going to watch Netflix and my whole computer was being a bit jumpy and laggy so I opened task manager and had a look, chrome was using 3.5gb RAM, OK I closed all my tabs, computer was still jumpy, I looked at the graph page of the RAM to see what was up and noticed that it says it's running at 933, half the normal speed so I powered off checked the RAM seating, booted into BIOS checked RAM speeed, it was 1866, booted to Windows re-opened task manager and it still says 933 which isn't even a speed option on the MOBO. Anybody had anything similar, or got any ideas of a fix.

 

Cheers

Set it to auto without X.M.P. and try then.

Not sure what setting in particular you mean but ive been through and set everything to auto. also tried changing the speed to 1600mhz and wierdly task manager still picks it up as 933mhz not the 800mhz I was expecting

You can set it to "auto" or use "X.M.P." settings. Check your BIOS manual. Something is set wrong (voltage or speed).
