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 the default 3000 MHz for DDR4 and then with a tweak enabled at 3333 MHz.

Default 2133 MHz 

What you will notice are already very decent dual-channel read and write numbers. You are hovering in the 43~46 GB/s range, which is good.

The DDR4 memory kit is rated at 3000 MHz. That, my friends, is configured by enabling XMP in the BIOS and that's it. However, Ballistix is also offering this memory as a 2666 MHz kit version as well. We suspect it's all the same. 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 3200 MHz with a lower CAS latency would not run on the Intel platform (it did on Ryzen though), however, 3333 MHz at advertised timings was stable:

Above - a tweaked frequency of 3333 MHz DDR4 - that's easy free bandwidth at the same timings.

 .. give it a go we'd say. It's ~10% extra bandwidth at no extra cost.
