Gigabyte breaks DDR5 memory overclock world record with 11GB/s transfer speeds

Gigabyte's in-house overclocker, HiCookie, has managed to break the world record for the speediest DDR5 memory overclock on an Intel Z790 machine, hitting 11Gb/s of raw, single channel bandwidth. 

That makes Gigabyte our new DDR5 memory overclocking champ, and only a hair away from reaching the likes of ADATA's upcoming DDR5-12600 production speeds (via WCCFTech).

The previous DDR5 overclock record involved a pair of G.Skill DDR5-8000 RAM modules, pushed to a whopping DDR5-10000 overclock on an Asus ROG Maximus Z790 Apex motherboard. 

Now, packing one of Gigabyte's own as-yet unreleased Aorus DDR5-8333 modules into a dual-DIMM Gigabyte Z790 Aorus Tachyon—a board designed specifically with extreme memory and CPU overclocking in mind—HiCookie has set the record at DDR5-11136 (5567.5 Effective).

That's with the CAS timings set to 64-127-127-127-127-2, as you can see in the CPU-Z validator results, though there's no data provided when it comes to memory voltages. A smart move in case anyone's planning to follow suit in a bid for the DDR5 overclock crown, and one that will mean a bit of experimentation on the part of any potential contenders.

The score is now listed as the maximum memory overclock on Gigabyte's Z790 Aorus Tachyon page, and is a big win for Gigabyte on the DDR5 overclocking front. 

Looks like we're getting very close to the ridiculous DDR5-12600 data transfer speeds ADATA has promised from its latest XPG memory announcement.
