– Limited availability

Unboxing & Walkaround

Here we have the fastest variants of the Kingston FURY BEAST DDR5 RGB rated at 6800MT/s, in the 2x16GB white-colored kit. While this is an XMP-certified module, Kingston also offers similar AMD EXPO-certified modules for Ryzen systems. Design-wise, it is quite different from the non-RGB variants of the same model, despite sharing the same name.

The RGB is very bright, and it can be synced with all the major RGB customization software, though you can also use Kingston’s own FURY CTRL software that should offer you more presets to play with. The modules feature Infrared Sync, which syncs lighting on both modules for a more uniform look.

Overclocking

Kingston FURY BEAST DDR5 RGB (DDR5-6800 CL34) Review - Plenty Fast, With Limited Headroom - 29
6800MT/s CL34-45-45-90 @ 1.4V

Starting with the defaults of 6800MT/s CL34-45-45-90 @ 1.4V, we have no problems in the 30-minute OCCT memory test. Latency is measured at 69.6 nanoseconds, and both its write and copy speeds are slightly slower than that of AGi’s UD858 TURBOJET DDR5-6800 modules.

7000MT/s CL34-45-45-90 @ 1.435V

First round of stress tests landed us here, the highest we can go while maintaining default timings (with the help of extra voltage). This nets us 2.4 nanoseconds in latency reduction, and a fair bit of improvement in Write and Copy speeds.

7200MT/s CL36-48-48-96 @ 1.435V w/ Active Cooling

We couldn’t go straight into 7200MT/s without loosening the timings as it’ll start spitting out memory errors otherwise – though with every help they can get, the modules did manage to pass the test at this clock speed and netting a healthy boost in Read speeds, while others only see minor improvements over the previous run. No attempts beyond this point is successful, though we did manage to at least POST at 7600MT/s – but the system is too unstable at that point to consider a safe overclock.

Verdict

The Kingston FURY BEAST DDR5 RGB (DDR5-6800 CL34) kit is generally solid, and you can gain a lot of performance for Intel systems on its default XMP settings from the get-go. That being said, you can squeeze just a bit more performance if you wish to, though the headroom is somewhat limited.

Still, I think the bigger issue currently is the lack of availability – this model can be found easily in most stores, but they’re almost always at slower clock speeds. There’s only one store we found thus far (costing RM891 for a kit of 2x16GB) that still has the fastest variant available, so you might need some luck if this speed is what you’re looking for.
