Adata is on a mission to see how far it can push its "blazing fast" XPG Spectrix D50 Xtreme RAM and has just achieved a DRAM effective frequency of 5,389 MHz. This is equivalent to DDR4-5400.

XPG is Adata's enthusiast and gaming division, similar to Asus and its Republic of Gamers (ROG) division. And just last week, XPG took the same memory kit to the heights of DDR4-5300 and overclocked the DRAM frequency to 5,298.8 MHz.

Last time, XPG paired this memory kit with MSI's MEG B550 Unify X motherboard and a Ryzen 7 Pro 4750G processor to run RAM at breakneck speeds. In this latest push, however, XPG replaced the testbed with a Gigabyte B550 Vision D motherboard and a Ryzen 7 4700G processor.

Adata offers two varieties of this RAM: DDR4-4800 and DDR4-5000; according to the CPU-Z screenshot shared by Adata, these results were obtained with the DDR4-5000 kit, which makes sense.

Running this fast also means that the timings would have to be loosened to 20-28-28-48. To put these numbers into perspective, G.Skill announced this week an extreme low-latency DDR4-3600 memory kit with 14-15-15-35 timings.

As we have examined in the past, RAM speed and capacity are somewhat important for gaming; AMD's Ryzen processors respond well to faster memory frequencies, up to DDR4-3600. On the AMD Zen 2 platform, memory clock and Infinity Fabric clocks run at a 1:1 ratio, and going higher doesn't make much sense, as it would take the processor past the point of best performance.

In the Ryzen 3000 series, the 1:1 ratio limit is technically 3,733 MHz; AMD has increased this to 4,000 MHz in the Ryzen 5000 series, but as the Ryzen 9 5900X review found, it is hit or miss in the early stages. When Alan contacted AMD about the Ryzen 5000 series not reaching its full memory potential at launch, he was told that the motherboard manufacturer was still optimizing memory for the AGESA code used to build the BIOS.

Nevertheless, optimal performance is still in the 1,900-2,000 MHz range, effectively DDR4-3800 to DDR4-4000, both well below DDR4-5400 specifications. Thus, while this is a clever tweak by Adata in the extreme memory region, one should aim for lower values when planning Ryzen builds and should be a bit more stringent with the timings for any build.
