I recently did a full upgrade on my PC and paired my new shiny 990 fx Asrock Killer mobo with 16gb of 1886 Crucial Balistix Tactical Tracer ram, however in bios I'm not getting the 1886 i hoped for, in fact the ram speeds selectable are really odd numbers such as 1645 and 1238 even as low as 690, Has anyone else had this issue? is it even possible to attain the 1886 speeds with this cpu and board? ( see system specs below ) if anyone has a solution or fix to get proper speeds back i would be grateful.

AMD FX 8350 Black Edition ( Corsair Hydro H100i cooled )
16 gb 1886 Crucial Balistix Tactical Tracer
Asrock 990 FX Killer AM3+
Nvidia GTX 660 TI ( upgrading as soon as 800 series is out )
OCZ 512 SSD ( OS drive )
3TB Seagate Barracuda Sata III
Corsair 850 Gold rated PSU
CM Storm Trooper
 


Tried that and it now clocks my memory @ DDR3 - 840.
And the selectable speeds are as follows - 840, 1119, 1399, 1680, 1959, 2239 and 2520...
Below is a SS of the memory page in CPU-Z using the settings you suggested.

Well, there is obviously something wrong here. Maybe resetting the cmos helps?
 


I have just performed an internet flash and have standard memory speeds back in the list however choosing 1886 from the list and saving and restarting upon entering bios again on reboot the speeds change back to 1333 default even when using XMP profile. that being said 1333 is way better than 840.

fresh image below of cpuz after flash and XMP 1.3 loaded auto set to 1333 obv something is still not, cleared cmos and still same.

I've no idea, why it is not automatically set to the XMP profile at 933 MHz. On the other hand I wouldn't think about it too much, because it is at least set to the optimized 9-9-9-24-33 mode for 666MHz. The speed difference between that an the XMP mode is irrelevant.
 


any ideas man? just seems sucky that I paid so much for the mobo and ram for it not to be working as intended.
