I have the kingston hyper x 3600 cl 17 32 GB kit (4x 8 gb)
They run at 3333 Mhz. If i use only two modules, i can hit 3600 mhz cl 16 and even 3733 mhz cl 16 (not fully stable).
With usb, i don't have issues (i use all usb ports).
Do you have these problems also with 2600 mhz?
Perhaps you can try to use only 16 gb ram.
I will sell two of the modules.
Edit: Have you changed bclk?
If i set something above 100 Mhz, i get problems with my HDDSs. A few of them won't show up in BIOS.
