Gigabyte announces D5 Single Boost, a BIOS-level tool for tuning single-channel memory

A stop-gap solution for the DRAM crisis, but only for Intel boards.

Amidst the DRAM shortage, Gigabyte has announced a new memory profile for its motherboards called D5 Single Boost. It’s a new BIOS feature that the company says is able to push performance from just one DDR5 module into the equivalent of two sticks.

Gigabyte states that D5 Single Boost can identify compatible modules by detecting whether they use Hynix M-Die chips. The BIOS – helped by Gigabyte’s D5 Bionic Corsa AI system – then profiles the specific module and adjusts the timing and voltage accordingly and in real time. These adjustments will be applied with every system boot.

The result is, according to Gigabyte, up to 8400MT/s from a single module, and a 10% performance gain in frame rates and load times for AAA games (though it didn’t list which games it tested it on). In short, it’s essentially an automatic memory tuner.

Gigabyte states that D5 Single Boost can grant up to 10% performance increases in AAA games, and can overclock a single module to 8400MT/s.

Of course, while Gigabyte will like to drum up the benefits of D5 Single Boost, you’d ideally still want to use dual-channel memory whenever you can, as it’s fundamentally an issue of bandwidth – there’s less of a bottleneck as the CPU can access the memory resources of both sticks simultaneously. 

Still, it’s a welcome feature considering the times we’re in. RAM prices are as high as they’ve ever been – taking a look at our Sim Lim price lists, the cheapest 32GB DDR5 dual-channel kits go for around S$500. If you’re still running single-channel memory alongside a Gigabyte board, or if you’re planning a build but the dual-channel memory prices are too prohibitive, D5 Single Boost may be a pleasant stop-gap until the memory crisis blows over.

On that note, Gigabyte stated that D5 Single Boost will only be available on Z890 and B860 motherboards, so no AMD systems will get this feature. Do also note that it only applies to Hynix’s M-Die memory chips – it’s an important distinction as not only does Hynix have different die variants, but memory chips can also come from other companies like Samsung and Micron. Tools like CPU-Z can tell you who which manufacturer made the DRAM in your memory module, but not the exact die, unfortunately.

According to Gigabyte, D5 Single Boost can be found on the latest BIOS updates (for applicable boards) from the company’s official website. Taking a look at the BIOS downloads for some of these motherboards, the last updates were uniformly released on 28 April this year, so if you’ve updated your BIOS since then, your board may already have this new feature.
