MSI had to sacrifice everything to achieve this 10,004MT/s DDR5 RAM overclock

MSI’s own overclocking team managed to push a single stick of DDR5 above the 5,000 MHz barrier to set a new record for RAM overclocking. The team used the company’s MEG Z690 Unify-X motherboard to push a single stick of Kingston Fury Beast DDR5-4800 RAM memory to 5001.8 MHz to provide an effective transfer rate of 10,004 MT/s. MSI says it hit 10,004 MHz, which is technically incorrect, but effectively identified due to how dual data rate RAM works.

There are always a lot of caveats when it comes to memory overclocking, and this is no different. Aside from just using a single stick of RAM and setting the latencies to a ridiculously slow 76, the rest of the system had to be heavily throttled to reach the downright ridiculous speed. This involved running the CPU at 425MHz and turning off all but one of the physical CPU cores.

The CPU in question? that would be Intel Core i9 12900KS. It’s not exactly a cheap CPU. And certainly not one you would normally see limping so much. Definitely not a chip you would normally see operating at a 4x multiplier, albeit with a bus speed of 106.42MHz. For reference the 425MHz CPU normally has a base clock of 3.4GHz and a Max Turbo of 5.5GHz.

This isn’t to lower memory overclocking – it’s a staggering bit of tweaking – but it’s worth pointing out that this isn’t an overclock you’d want to run on a 24/7 machine. I mean, you could, but it would be a pretty miserable experience.

The important thing here is that the promise of DDR5 hitting 10-12GT/s is still very much alive and well. That Kingston memory can reach these frequencies is the important thing here. Well, that and the skill required to actually achieve such a feat.

DDR5 did not have the easiest start in life, with prices being affected by silicon shortages and also being hit by ongoing closures due to Covid. Still, the standard is sure to get a boost when AMD’s Zen 4 launches later this year, which will apparently launch with only DDR5 support.
