G.SKILL Trident Z RGB DC Series
Date 17th July 2019
Author headin2001
Editor James "Agg" Rolfe
Manufacturer G.SKILL


Test Setup:
CPU – Intel i9 9900K
Cooler – Coolermaster Master Liquid Pro 280
Thermal Paste – Coolermaster Mastergel Maker Nano
Motherboard – ASUS ROG Maximus XI Gene (Z390)
G.Skill TridentZ 4266C19 (F4-4266C19D-GTZSW) or
G.Skill TridentZ RGB DC 3200C14 (F4-3200C14D-64GTZDC)
Storage – Team Group T-Force DeltaR RGB 250GB (OCAU review here)
Graphics – ASUS DirectCUII GTX 750ti
PSU – Coolermaster MasterWatt 1200
OS – Windows 10 Pro x64 Build LTSC

For benchmarking, I have chosen software to highlight CPU and memory performance:

Cinebench R15
Cinebench R15 Extreme
Intel XTU (tests both CPU and memory performance)
wPrime 1024m
SuperPi 32m
Geekbench 3
Geekbench 4
Aida64 – Memory Benchmark and Latency
3DMark Timespy – CPU Test

Each benchmark was run 3 times, and the best score recorded, discarding any obviously glitched runs. CPU speed, Cache Multiplier and Voltages were manually set to avoid differences between reboots. Memory XMP was also set, with MemOK jumper enabled on the motherboard for consistency.

I have omitted any overclocking results on these DIMMs, and there is a reason for this. Basically, there was just no room for it to move that was worth the hours of messing about. For those that want a bit more, I was able to achieve a 3250 C14-14-14-34-1T speed, but it was a big headache to get there, and not always happy to boot. Any more and it would simply not improve, for me anyway. I have seen others stretching these into the 3400 C16 to 3500 C16 realm, but my setup just purely would not let me progress at all. I put this down to the differences in trace lengths to the PCB, interrupting the signal and limiting how much further they can go. Maybe with further improvements in the design higher speeds could be achievable, but at 3200 C14-14, to me it’s in a pretty sweet spot for performance and cost.

Well, there we go, another great product run through its paces. Surprisingly, at XMP settings, the benchmarks all show relatively close results between the different memory bins, with some of the multicore benchmarks showing the lower speed, tighter latency having a beneficial result. Under the heat spreaders are the now infamous Samsung B-Die IC’s, which aid in the nice tight timings compared to others.

For those that love the smaller motherboard form factors like the ROG Maximus XI Gene in mATX factor or the smaller Strix Z390-I Gaming but still wish to have the 9900K and as much memory on tap as possible, there is no other option for RAM to give the full 64GB allowable on the platform.

Price wise, there is a premium price to pay here in Australia. Some stores show from $1250 AUD and upward, compared to a 4x16GB kit with the same speed and latency only costing around $1070 AUD at time of writing.
