Gigabyte announces DDR5-8333 and DDR5-9300 OC support on select Aorus motherboards

It’s over 9,000!

Gigabyte Z790 Aorus Master

Gigabyte has managed to run super-fast DDR5 memory on some of its top-tier Aorus motherboards, achieving 8,000MT/s and 8,333MT/s speeds simply by activating XMP, with up to 9,300MT/s via overclocking. Wowsers.

Starting small with what is the most affordable of the bunch, the Gigabyte Z790 Aorus Master achieving 8,000MT/s by using XMP 3.0 profiles. In other words, something that is technically obtainable by anyone who grabs this combo. From the published screenshots we can also see the 32GB kit has the ARS32G78D5 part number, meaning, if not mistaken, the Aorus series 32GB 7,8xxMT/s DDR5. The memory kit was set to 36-45-45-75 timings and coupled to an Intel Core i9-13900K (ES) processor.

Moving to a higher-tier Z790 Aorus Tachyon board unlocks DDR5-8333, again using XMP 3.0 and an i9-13900K (ES). The part number on this kit is ARS32G83D5, probably for the Aorus series 32GB 8,3xxMT/s DDR5. The timings were unsurprisingly a bit higher at 38-48-48-78, as was voltage which sat at a toasty 1.55V – far from the original 1.1V.

This last part was also tested onboard a Z790 Aorus Tachyon reaching a blazing-fast 9,300MT/s with 46-58-58-62 timings on air. Not a world record, of course, but plenty fast, nonetheless.

Interestingly, the 9,300MT/s overclocking seems to have been achieved using DDR5-7600 instead of DDR5-8332. But that’s how overclocking works sometimes, a higher starting point doesn’t necessarily ensure a top spot after OC. With that said, Gigabyte didn’t show any tests at this frequency, which may indicate poor stability or a performance regression. Not a problem, mind you, since this is clearly a showcase and not a 24/7-running scenario.

The brand says these improvements are helped by new-generation Shielded Memory Routing and low-signal-loss PCB design coupled with abundant BIOS settings for DDR5 memory.

One of the fastest memory kits available for grabs today is from G.Skill’s Trident Z5 RGB Series running at only 7,600MT/s out of the box using XMP. A far cry from the DDR5-8333 kit showcased by Gigabyte, not even mentioning the 9,300MT/s OC.

It would be interesting to see from what point these super-fast DIMMs bring merely marginal performance uplifts. Is it worth having future 10,000MT/s or 12,000MT/s memory? Only time will tell.
