Performance - DDR4 System Memory
Performance System Memory: Memory Read Test
For our memory tests, we have used the kit that AMD supplied, dual-channel at 3600 MHz at CL18. Typically we make use of 3200 MHz CL16 or 3200 MHz CL16 for all tests. A note on write performance: According to AMD, this is normal behavior. AMD claims that client workloads do very little pure writing, so the CCD/IOD link is 32B/cycle while reading and 16B/cycle for writing. This allowed AMD to save power and area inside the package to spend on other, more beneficial areas.
