Corsair Dominator Platinum 3200MHz DDR4 64GB Testing:

Memory is often hard to separate from one kit to another in gaming, but when it comes to number crunching and computing, some memory provides an extra boost in comparison. To see just what kind of performance this kit has to offer, I will be running the modules through a series of benches to see just how they compare. SInce I only have a pair of DDR4 modules, these will represent the comparison field. Each kit will be tested at its native native speeds, as well as overclocked. Overclocking, of course, will be dependent on exactly how far the testing rig will allow, but I'll push it as far as I can. The testing set up used for these benchmarks is listed below, with the XMP profile applied to show where the modules settle in at after training. The CPU will be run with default XMP settings with the CPU running at the XMP 2.0 set 4.0GHz for the basleine testing. The memory will then be overclocked while keeping the clock speed as close to 4.0GHz as possible for OC testing. All current updates and patches are installed for Windows 10 64-bit and the latest driver for the NVIDIA GTX 1080 Founders Edition will be used.

Overclocking:

Overclocking 64GB of DDR4 proved to be a bit challenging for my particular CPU's memory controller. Loosening the timings and increasing the applied voltage as high as 1.5v did not let me push the kit any higher than 3310MHz. That being said, I was able to tighten up the timings on the modules to 15-17-17-36 at 3200MHz using 1.4v and run fully stable through both LinX and Prime95. Corsair's Dominator modules are well equipped to handle the extra voltage with custom PCBs that are connected to the exclusive DHX cooling system that integrates the cooling system directly onto the PCB, keeping the PCB and traces, as well as the memory ICs, cool.

To reach 3310MHz I increased the processor bclock to 103.7MHz on the processor while leaving the memory at the XMP 2.0 set 3200MHz ratio in the BIOS. Now, 110MHz is not that large an increase, but is on par with some of the modules I have tested in the past with higher speed bins.

 

 

 

Maximum Memory Speed:

The maximum memory speed for each set of overclocked modules is indicative of how well the modules ran on this test system. As such, your results may differ in either a positive or negative way based on the capabilities of your hardware. In other words, your mileage may vary!
