Ram not running at spec speeds?

[Erik8086]

Hello community,

 

I am gracefully asking for help.

 

HELPPPPP!!!

 

I recently bought 2x 16G DDR4 2666mhz vengence LPX ram sticks to upgrade my old aurora R6. In bios I cannot acces anything in my perfomance tab and my memory is only runnung at 2133mhz. I have the base I5 7400 from intel (not overclockable). From the specs, here below, I should be able to run these speeds. What should I do?

 

I am just starting as a computer enthusiast and english is not my first language so sorry if I am not clear. 

 

Thank you in advance for all the help!

Does your motherboard support XMP?

Because you cant acces the one tab in BIOS, I would try to flash it and update it to the newest version. Also before doing that you could try to clear cmos.

NineEyeRon : According to spec in the pdf I looked and shared yes!

 

icy330 : I checked the version of the bios and the one installed is the latest... I even reinstalled it for good measure. I'll try to clear cmos (I don't even know what it is but I am sure google can help me there!)

 

Thx for the time guys!

 

Ps Tried clearing cmos and it didn't change anything, removed MB battery and tried resetting to default in bios....
