G.Skill TridentZ RGB DDR4 memory review - 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 SPD/JEDEC 2133 MHz for DDR4 and then with XMP 2.0 enabled at 3600 MHz.
 

Default 2133 MHz - Boring !

What you will notice are pretty far our dual-channel read and write numbers. These are the default SPD timings. You are basically hoevering towards 30~32 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 3600 MHz. That my friends is configured by enabling XMP in the BIOS, and that's it. All of the sudden, the memory bandwidth numbers will chance dramatically:
  

Above - Default clock frequency on CPU / 3200 MHz on DDR4

Hello 47 to 54K 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 could see little gains. 

Let's chart it up:

So here a mixture of dual and quad channel reults varying with processors and platforms. We tested the memory as highlighted in the charts Now with the regular memory at 2133 MHz versus AIDA memory tests we see good performance hovering at the 30K marker, and with a 3600 MHz kit, you are reaching 47~48K GB/s (dual-channel).

Memory Write Test

We obviously did the same with the memory write tests. The Write perf jumps to 54K at 3600 MHz at dual-channel. Just enable XMP in the BIOS and you are good to go.
