G.Skill has announced its new 32 GB “Double Capacity” memory modules. The Trident Z RGB DC DIMMs are compatible only with select Z390 motherboards from ASUS, and while they do not feature extreme data transfer rates, those who need a lot of memory this is hardly a limitation.

The G.Skill Trident Z RGB DC memory modules are based on 32 Samsung B-die 8 Gb DRAM devices. In fact, the manufacturer says that the “Double Capacity” DIMMs are essentially two modules on one PCB: they feature not only two times the usual number of memory chips, but they also have two EEPROMs/SPDs, etc. Meanwhile, the new UDIMMs feature a slightly different pinout and layout than JEDEC-standardized modules, so they are compatible only with ASUS's ROG Z390 MAXIMUS XI APEX, ROG Maximus XI Gene, and ROG STRIX Z390-I GAMING motherboards.

G.Skill’s 32 GB Trident Z RGB DC UDIMMs will ship in dual-channel 64 GB kits rated for DDR4-3000 (CL14) and DDR4-3200 (CL14) speeds at 1.35 V. The modules fully support XMP 2.0 SPD profiles for simplified overclocking. Speaking of overclocking, it is necessary to note that Samsung’s B-die DRAMs are the widely considered the best memory chips for overclocking, so the odds are fair that the modules will be able to work at higher data rates when in good hands.

Just like other Trident Z RGB DIMMs, the “Double Capacity” modules come with aluminum heat spreaders outfitted with addressable RGB light bars.

The new unbuffered 32 GB Trident Z RGB DC memory modules will be available shortly. Considering that these are unique UDIMMs compatible only with a small number of motherboards, expect these products to carry a premium price tag.

    I predict very large numbers of 1 star reviews and extremely high return rates from consumers who fail to read the specs closely enough; and assume the ram will work on their board because it's DDR4 and they have DDR4 and either didn't see the compatibility list at all or assumed it was just a "we tested with" list, not a "these are the only boards to support the non-standard stuff we did to make this work.

    This specialty memory and the validation process just for those boards and the sheer capacity of these... It's just going to be priced out of 99.9% of people's reach. So I kind of doubt that people would buy these in droves to leave "very large numbers of 1 star reviews"... Reply

    Yup, there will be a lot of confused consumers out there that don't know and send them back for a refund. I hope those pin changes don't cause a short circuit that releases the magic smoke on standard motherboards. That would be fun for G.Skill's support department to deal with. Reply

    But why make them this way? It's possible to make normal 32GB UDIMM's as evidenced by the (very hard to get) Samsung 32GB ones that exist. Reply

    Presumably because no one can get the DRAM that Samsung uses for those? As you've accurately noted, it's very hard to get. Reply

    The problem is that 16Gbit DDR4 isn't common yet. Reply

    Why are companies going this route rather than just producing 32GB standard DIMM's like Samsung is doing? Reply
