Intel Core i9-10900K CPU & Z490 Platform Memory Performance With G.Skill Trident Z Royal 4400 MHz CL18 & T-Force Xtreem ARGB 3600 MHz CL14 Memory Kits


Memory Kits Performance Tests on Intel Z490 Platform

Intel Z490 / Core i9-10900K Memory Test Setup

For testing, I used the latest Intel Core i9 10900K processor along with the ASUS ROG Maximus XII HERO motherboard which can support higher frequencies memory without any issues. The XMP profile for each respective ram kit was enabled. That's 4400 MHz CL18 for the G.Skill and 3600 MHz CL14 for the T-Force kit.

The memory kit comprises of 2 DIMMs that operate in dual channel mode. Since we were running a Z490 platform, the memory was operating in dual channel mode. Additionally, I managed to get an overclock of DDR4-3733 MHz with the T-Force kit while retaining the CL14 (14-15-15-35) timings at 1.5V. For G.Skill's kit, I pushed the memory up to DDR4-4600 MHz with CL19 (19-19-19-38) timings at 1.5V or DDR4-4000 with CL16 (16-18-18-36 2T) timings.

DDR4 Memory Kit Performance Tests With Intel Core i9-10900K

I have separated the performance tests into two sections. The first section consists of pure synthetic and general workload tests while the second section would be focusing on gaming performance and how different games are affected by higher clocked memory sticks.

AIDA64 Memory Bandwidth Benchmark

For AIDA64 memory tests, I ran the kits at both at stock and overclocked speeds. The stock speed was configured at the XMP profile of 3600 MHz CL14 for the T-Force and 4400 MHz CL18 for the G.Skill kit.


Super PI is used by many overclockers to test the performance and stability of their computers. In the overclocking community, the standard program provides a benchmark for enthusiasts to compare “world record” pi calculation times and demonstrate their overclocking abilities. The program can also be used to test the stability of a certain overclock speed.

Gaming Performance Tests

Gaming applications generally don't see huge gains with different memory kits but DDR4 has enabled a huge gain in memory frequency which can impact gaming performance. Moving from the stock 3200 MHz to 3600 MHz and beyond 4000 MHz can have a slight effect on performance and the improved CAS timings on some of the high-end SKUs can result in better overall FPS and system responsiveness.

Furthermore, while 8 GB has become the standard for gaming PCs, modern applications such as editing software and multi-tasking users can benefit hugely from 16 GB and 32 GB kits which have become more common in the gaming market over the last couple of years.
