DDR3-1900Mhz 6-8-6-24 1T at 1.62v
(Kit 1: module #5 + #3 + #6)
Testing CAS6 clocks, with 6-7-6-24 1T at 1.62v max memory frequency came to DDR3-1720Mhz (860mhz), but loosen tRCD from 7 to 8 and max memory frequency jumped to DDR3-1900Mhz 6-8-6-24 1T at 1.62v! Using same same tFAW = 34, B2B = 4 and DDRAM Data/CTRL VREF A/B/C tweaks as my
8-9-8-24 tests for HyperPi 8x32M and single Super Pi 32M.
