G.skill Trident Z5 Neo RGB 6000 CL30 EXPO
2. Tests
For our tests, we used the following test system
- AMD 7950X CPU + Noctua NH-U12A Chromax.black (2x120mm fans)
- Asus ProArt X670E-CREATOR WIFI Motherboard with the latest BIOS installed (1415 AGESA 1.0.0.7a)
- MSI 4090 Suprim X Graphics Card with v535.98 Nvidia Drivers installed
- Samsung 980Pro 1TB with the latest BIOS NVME SSD
- Seasonic Vertex GX 1000W Power Supply
- Dell S2721QS 4K Monitor @ 60Hz
- Windows 11 Pro Edition + latest updates installed
- Test Stability:
- quick testing 30min OCCT v12 Memory Test
- stable testing Testmem5 absolute(01102021)@anta777.cfg (3 cycles)
Both modules were installed at the B2/B4 channels suggested by the motherboard vendor. We had to manually perform ClearCMOS to get everything started and the memory training for the DDR5 platform with the Asus motherboard isn't long, the first boot came around 20 seconds, and the first power up. After that point, the system is much faster at boot.
After getting the first boot, the Asus motherboard recognized and set the memory initially at DDR5-4800MHz CL40 1.10V, without enabling any EXPO/XMP profiles. Under the BIOS motherboard, we can set the EXPO / XMP profile, for the AMD system there is only one choice, DDR5-6000 CL30. Getting into Windows 11, we get more information about our memory kit from the CPU-Z software. The memory kit was manufactured in the 13 weeks of 2023 and has both JEDEC/EXPO profiles, but not XMP as other manufacturers do...
Using the free latest version of the Thaiphoon Burner which includes more information about the used modules.
The (default) memory setting runs at 4800MHz with CL40 and v1.10V
The EXPO profile runs at 6000MHz with CL30 and v1.35V
From our testing, you can get tighter timings at 6000MHz with CL30 and 1.35V. Note that you may get worse or better timings depending on your system and voltages. We also pumped the FCLK to 2133MHz that supposed to give higher performance as well.
The Asus motherboard also includes other memory presets for Hynix-based memory kits (Ai Tweaker->DRAM Timing Control -> Memory Presets. You will find two additional Hynix memory presets (6200 1.4V 2x16GB SR / 6400 1.40V 2x16GB SR), which are also used to gather further performance numbers. Note that even if you enable the presets, you need to manually change the memory frequency to the corresponding speed (6200 / 6400). From our tests only the DDR5-6200 preset was "stable", the 6400 memory preset was crashing the system despite pumping up the voltage to 1.45V.
For our tests, we performed tests at all above running speeds to showcase all possible scenarios you could run this memory kit.
AIDA64 Cache And Memory Benchmark (v6.88.6423)
The highest memory performance comes from the 6200CL30 which needs 1.40V to be stable. The 6000CL30 OC version we tried has also very good performance, at least much better than the stock 6000 CL30 timings. Considering cache latency, the CL6200CL32 gave around 58.4ns, while the CL6000 CL30 OC version gave under 60ns, which is very good, and much better than the stock 6000 CL30 EXPO setting.
MemoryMark (Performance Test 10.2 Suite)
This test gives an overall score for the installed memory, the 6000CL30 OC is close to the CL6200 CL32, while the "stock" 6000 CL30 falls behind with 4096 points.
Passing to the well-known GeekBench, this software tests the performance either in single or total cores, and as we can see there is a performance difference in both single/multi-core index scores as memory frequency rises.
We used the latest version of the well-known PCMark10 and we saw some performance differences in the total overall score, after setting the various memory frequencies of the tested memory. The 6000 CL30 OC memory setting gave the highest overall score with 10394 points, while the 6200 CL32 was slightly behind with 10367 points.
With the 6000MHz EXPO setting and 1.35V the modules started from 32 Celsius and under heavy load reached around 60 Celsius (max temp) at 1.35V. For sure the included heat spreader will help maintain system stability even at extreme loads.
Using an open-source benchmark software called MicrobenchmarksGui, we made two graphs of the various memory frequencies and the cache latency as measured by the software. The cache latency of both 6000 CL30 OC and 6200 CL32 seems to be very similar,
, while the memory bandwidth of the 6000 CL30 OC preset will give you mostly higher performance in most test memory sizes.
