DDR3 1600MHz running at 1333MHz

[Borealis]

I've just rebuilt an AMD machine using a Gigabyte GA-970A-UD3 and plugged in 16GB of Kingston HyperX Black CAS 10 running at 1600MHz.

Only problem is the BIOS only detects it as 1333MHz. I believe this is due to 1600 technically being an overclocked profile. I've never had to mess around with the memory settings before because my other builds all detected the RAM fine, so I'm not sure what I need to adjust in terms of timings/voltages to get it running at 1600MHz.

Apologies if this has already been answered a thousand times but any advice would be very handy!

Thanks for the suggestions. Yup, same CPU and motherboard as per my other thread. I looked in the M.I.T and found the DRAM E.O.C.P.

First time I set the "DDR1600" profile and "optimized voltages" only to find it crashed on reboot - must have been slightly off. Tried again with a mysterious "Profile 1" (must be the XMP profile) and it seems to be perfectly stable at 1.5V

So far so good!

This motherboard seems to have several stock OC profiles listed under DRAM E.O.C.P. - there were profiles from 1600 to 2000MHz and above I think.

When I tried one of those, the machine crashed, so I went for Profile 1 instead and it seems to work well.
