Memory will only run at 1600. contacted gskill to no avail they blamed it on bios, updated bios, same issue. I get bsod at windows login gskill says 9,10,9,28 with 1.5 dram voltage. But doesnt work. all help appreciated (new to overclocking so please be specific and patient )
Get a RMA # if they are not running at manufacture's specifications. You didn't list the model but you should double check the side of the ram and make sure you got the correct kind. If you did and you are manually entering these times and are receiving BSOD you will probably want to return. You could run Memtest as well to see if one of the sticks is faulty. But either way I'd exchange/return them.
Note to check if these sticks are supported with your board.
gskill and newegg both told me that the sticks are supported by this board. I have also found references to this combo in forums but with no instruction to my current issue. model number is f3-14900cl9q-16gbxl
Do as scout_03 said if you haven't already and compare results with cpu-z. If the specs are still off then RMA time unless you don't mind the 1600 clock which isn't going to be a noticeable difference from the 1866 anyways.
