I am using 8 DRAMs on my X99 buiuld
4x ADATA 8G DDR4 2400
4x Kingston FuryX 8g ddr4 2400
I am getting extremely low speed on memory benchmark such as AIDA64 and MaxxMEM.
It was even slower than my dual channel DDR3 1800 on my Z87.
This is the benchmark score for default setting 15-15-15-36 2133mhz
I have tried manually set 12-12-12-32 2133mhz as well. There is about 10-20% of performance increase, but it is still way slower than normal quad channel. (I am using Xeon E5, so the memory is locked at 2133mhz).
