System Memory Bandwidth Performance

System Memory Bandwidth Performance

As explained - Intel has a couple of certified partners for memory to get some sweet XMP (Xtreme Memory Profiles) 2.0 profiles going. We test memory both at 3200 MHz for DDR4 and then with a tweak enabled at 3600 MHz.

 Default 2133 MHz 

What you will notice are already very decent dual-channel read and write numbers. At 3200 MHz CL16, you are basically hovering in the 46~48 GB/s range, which is excellent.

The DDR4 memory kit is rated at 3200 MHz. That, my friends, is configured by enabling XMP in the BIOS and that's it. For a manual tweak, in the BIOS enable XMP, set Voltage towards 1.35 Volts and then increase the memory frequency until it crashes. For us 3866 Mhz would not run, however, 3600 MHz with the very same timings was totally stable:

Above - a tweaked frequency of 3600 MHz DDR4 - that's easy free bandwidth at the same timings.

Hello, 51K GB/sec ranges. Since the 3200 MHz kit is cheaper .. give it a go we'd say. Gotta love Samsung B-Die.
