Gigabyte Intel 800/700/600 Series Motherboards Now Fully Support HUDIMM
Gigabyte Technology Co. Ltd, a leading manufacturer of motherboards, graphics cards, and hardware solutions, today announced a comprehensive BIOS update rollout for its Intel 800, 700, and 600 series motherboards, adding full support for the newly introduced HUDIMM (One Sub-channel DDR5) memory standard. The move reflects Gigabyte's ongoing commitment to empowering users at every budget level, particularly as global DDR5 memory prices remain elevated amid continued supply constraints.
Lowering the Cost of Building on DDR5
One Sub-Channel is a new DDR5 memory specification that utilizes a single 32-bit sub-channel instead of the dual 32-bit sub-channels found in standard UDIMM modules. By adjusting the DRAM chip count per module, HUDIMM (One Sub-channel DDR5) enables memory manufacturers to provide DDR5 sticks at significantly lower price—making modern DDR5 platforms more accessible to mainstream users, system integrators, and entry-level builders who have previously been priced out of the DDR5 ecosystem.
Gigabyte's updated BIOS firmware enables seamless detection and initialization of HUDIMM (One Sub-channel DDR5) modules, ensuring stable operation with no additional configuration required from end users.
Flexible Mixed-Configuration Support
One of the most practical advantages unlocked by Gigabyte's HUDIMM (One Sub-channel DDR5) ready BIOS is the support for asymmetric memory configurations. Users can freely pair a HUDIMM (One Sub-channel DDR5) module with a standard UDIMM stick—for example, combining an 8 GB HUDIMM (One Sub-channel DDR5) with a 16 GB UDIMM—to achieve unconventional yet cost-effective capacities such as 24 GB, while benefiting from the combined bandwidth of three DDR5 sub-channels. This flexibility gives users a cost-efficient upgrade path without requiring a complete memory kit replacement.
Update Now, Unlock HUDIMM (One Sub-channel DDR5)
The BIOS update covers Gigabyte's full range of Intel 800, 700, and 600 series motherboards. Gigabyte encourages all users to update to the latest BIOS version via the Gigabyte website to enable HUDIMM (One Sub-channel DDR5) compatibility. BIOS updates with HUDIMM (One Sub-channel DDR5) support are available now, please visit Gigabyte official website for download.

Thank you AI. It's hard to decide what result of this glorious tech I like the most - job losses, price hikes, hardware unavailabilities, tech regressions - DDR4 re-launch, RTX 3060 comeback, and now this "Double data rate / but halved" monstrosity...
How long before we get to this?
Not that they arrive at the conclusion to sell this “special” format as the new normal for inflated prices. :fear:
Or they want to trick consumers because there're two DIMM's instead of one!!
Now, realistically speaking, you would want to replace any HUDIMMs immediately if prices ever crash, but interoperability is never a bad thing.

This will be used to scam people for years to come. Buying second hand ram will be complete lottery thanks to this crap.
You think you can tell by number of memory chips? Haha, good luck with that, under the heatspreader surrounded by thermal pads.
Even worse, usual Aliexpress suspects will make sticks with fake dummy chips on one side so it looks fully populated even if you look under the HS.
Thanks greedy AI companies for turning DIMM buying experience into same crap as buying a USB flash drives, where everything is fake until proven otherwise.
GREAT. Just great.
Also, to hell with this abortive "invention". :nutkick:Oh yeah? Then I'm encouraging Gigabyte to stop supporting garbage half-baked slop gimmicks and to do more competitive products, I don't see their mobos being very popular choices and regarding GPUs their thermal gel is definitely up there when it comes to "innovations". 👎
