I recently bought a Hyper X Fury 8x2 with XMP frequency of 1866 MHz. My motherboard is a ASRock H97M-itx/ac which is so fucking shitty that it does not support any frequencies above 1600 MHz. So I thought I'd make the most out of this mistake of buying RAM higher than what I can support by downclocking the frequency and decreasing the delay of the RAM.

Currently my RAM timings are:
DDR3L-1600 CL9-9-9 @1.35V
tRAS: 28
tRFC: 200
CR: 1T

The memory supports DDR3L-1866 CL11-11-11 @1.35V as XMP and JEDEC/PnP: DDR3L-1866 CL11-11-11 @1.35V/1.5V, DDR3L-1600 CL10-10-10 @1.35V/1.5V, DDR3L-1333 CL8-8-8 @1.35V/1.5V

Currently, everything seems stable and I just want to know if I can lower the RAM timings further or is this fine enough?

FYI: There are no XMP/JEDEC profiles for 1600 MHz. I got those numbers from the manual.

I heard that each session of MEMTEST has to be at least 6 hours to ensure that the RAM is stable. It also costs $40 and I don't have that kind of money on me currently :/
