MSI Z97 Gaming 5 Code 26

[iCompute-doU]

I just got a replacement RMA board from MSI and it doesn't seem to boot with more than one of my RAM sticks in.

Setup:

Intel i5-4690K; DeepCool Liquid cooler.
2x8gb HyperX 1866MHz (HX318C10FRK2/16)
1TB WD Blue
CS-550M Corsair PSU
MSI GTX 960 Gaming

So it gave me an error code "26" upon booting with 2 sticks, which sounds like it's an incompatiable RAM problem. I've already flashed the BIOS to the most recent version. It boots fine with one stick of the aforementioned RAM, but not with two. I checked the compatibility list and this specific RAM isn't on it. It suggests the model HX316C10FRK2/16 instead, which is identical except for the operational clock speed of 1600MHz instead of 1866.

Is the solution just to replace the RAM I have with it's slower version? Not that the speed makes a big difference anyway....

Those two RAMs aren't identical. Besides different speed, they also have different timings.

HX316C10FRK2/16
DDR3-1600 CL10-10-10 @1.5V
DDR3-1333 CL9-9-9 @1.5V
DDR3-1066 CL7-7-7 @1.5V

HX318C10FRK2/16
DDR3-1866 CL10-11-10 @1.5V
DDR3-1600 CL9-10-9 @1.5V
DDR3-1333 CL8-9-8 @1.5V

To fix your RAM issue, get a RAM set that is compatible with the MoBo.
