System Memory Bandwidth Performance
System Memory Bandwidth Performance
As explained - Intel has a couple of certified partners for memory to get some sweet XMP (Extreme Memory profiles) 2.0 profiles going. We test memory both at the default JEDEC 2133 MHz for DDR4 and then with XMP 2.0 enabled at 3200 MHz.
Default 2133 MHz - Boring !
What you will notice are pretty far our dual-channel read and write numbers. You are basically hoevering towards 32 GB/s GB/sec range. Things however will get more crazy quickly, behold the coolness below:
G.Skill send out the TridentZ DDR4 memory kit rated at 3200 MHz. That my friends is configured by enabling XMP in the BIOS, and that's it. All of the sudden, the bandwidth numbers will chance dramatically:
Above - Default clock frequency on CPU / 3200 MHz on DDR4
Hello 45 to 48K GB/sec ranges! So if you like to go a little more crazy in bandwidth, purchase some nice compatible faster XMP ready memory and enable that XMP profile in the BIOS. Faster memory is relative though, your overall PC experience will not be much faster, yet memory intensive applications like say transcoding or a CPU limited game that where you will see little gains.
Let's chart it up:
We tested the memory on the ASUS Maximus VIII Formula as highlighted in the charts Now with the regular memory at 2133 MHz versus AIDA memory tests we see good performance hovering at the 31K marker, and with a 3200 MHz kit, you are reaching 45K.
Memory Write Test
We obviously did the same with the memory write tests. The Write perf jumps to 33K at 2133 MHz and 48K at 3200 MHz. G.Skill TridentZ DDR4 kits gents, enable XMP in the BIOS and you are good to go.
