Leak Indicates G.SKILL Prepping Non-Binary 24 GB DDR5 Memory Modules w/ AMD EXPO Support

Hardware leaker MEGAsizeGPU has uploaded photos of unreleased G.Skill DIMMs—they claim that the leaked hardware "is the world's first 24G*2 DDR5 expo module: F5-6000J4048F24GX2-TZ5NR." The next-gen Trident Z5 memory is said to be rated for a 6000 MT/s data transfer rate, and close-up shots of labels on heatsinks point to the sample units being non-binary 24 GB DDR5 memory modules that can support EXPO profiles for AMD's Ryzen 7000-series CPUs. MEGAsizeGPU claims that "6000 MHz is the sweetspot for Ryzen" (AM5).

Off-screen captures show a PC system booting up in DDR5-6000 mode—within a Windows OS environment, CPU-Z demonstrates that these new Trident Z5 modules are based on SpecTek-made 24Gb DRAM ICs (instead of binary 16Gb)—SpecTek is a division working under Micron Technology. G.SKILL will likely be selling non-binary Z5 memory in pairs, so we expect to see matched 48 GB dual-channel kits popping up on the market soon. MEGAsizeGPU did not mention anything about pricing or availability. Kingston debuted its own non-binary memory offerings at Computex 2023, but presentation material on hand did not mention whether their new models support AMD's Extended Profiles for Overclocking (EXPO).

AnarchoPrimitivAm I the ONLY one who doesn't understand what the big deal about 24GB/48GB ram for consumers is? Needing exactly 48GB as opposed to 32GB or 64GB or needing 192GB over 128GB must be an incredibly niche application....what am I missing?
Ability to use 96GB instead of 64GB on memory OC focused boards with two DIMM slots.

Also on CPU with cores in multiples of 6, while running VMs you can have 4 or 8GB RAM/core.

For rizen most important factor is timings, 2x32gb cl30 and you are set, at moment as far as I know, 2x48gb would need cl40 to be stable.

ir_cow@phanbuey just a tease with a RTX 4090 :) both have the same primary timings. Also I realized I wrote 5200 and not 5600. Oops! Time to fix that.

So completely useless unless you need 48Gb instead of 36GB for some reason which makes no sense for gaming ..... for productivity workloads 64GB makes more sense .

Well if you pick a ''memory OC focused board'' your focus is to OC the ram not to have tons of ram .... 32GB of ram will do for most competitive OC tasks .

Why does exact amount per core or per VM matter? My only experience with VMs is with Virtualbox but I haven't seen issues when I set memory size with a slider to something like 12345 MB.
natr0nIt's like what nvidia does already for many years odd ram sizes like 5 or 11gb

My xeon system has 6x8GB sticks for 48gb in hexa channel config.
Not exactly. Here, each DRAM die has a non-power-of-two capacity, which very probably is a first.

The capacity is exactly 110 0000 0000 0000 0000 0000 0000 0000 0000 bits, obviously a non-binary number.

Timings seem to be a bit worse than on my already not-the-best 32 GB Corsair kit, but that shouldn't be a problem, I guess.

Yes but this is only one example. Two other examples are those who use mITX boards that have two slots. So compact computers but need more than 32GB or 64GB. Also those on cheaper boards that have two slots for memory.

G.Skill has 2x48GB 8000 kits. I see no reason why they would not be able to produce 2x48GB 6000 CL30 kits too.

Dual Rank generally has loser sub timings compared to single rank. You can often match primaries though. I should see how low I can go with this GKILL kit. I only went up so far.

phanbueyYeah I cant wait for the reviews to see how these actually perform.
Exactly the same its just more capacity

I think someone on the forum mentioned in the past that this can be useful for virtualization. You can dedicate 128GB ram for VM's and have a bit left over for the OS or hypervisor.
trsttteI think it's just a lame attempt at clickbait and controversy trying to connect a topic with current culture wars
It's like back in the day the issue with HDD master vs. slave. It had nothing to do with promoting actual slavery but somehow someone saw fit to "correct" industry lexicon and change it up to primary vs. secondary instead so it wouldn't be offensive? I just want my PC to be my Personal Computer not necessarily Politically Correct or a platform for Policed Coercion.

Not exactly. The physical size of the chip is larger, revision obviously isn't the same. It's a bit harder to achieve same speed and timings with a larger chip.

Honestly if you need more than 64GB for your workflow then chances are you won't use a two dimm mobo ... that's an extremely edge case scenario at best .

Anx yet it can be represented in binary. Odd, no?

That's well and good if you know ahead of time what your work requires. Edge-case is finding excuses why we dont need bigger capacity individual DIMM's.
And already four DIMM DDR5 boards are pointless for most people. Not just the ones going for speed over capacity.

All I see are 1's and 0's

perfectly binary ;)

I'd like to see what you can do with this kit

Yeah. The 12 GB on my 6750 XT has never been called non-binary.

I mean that the same specced xmp/expo kits will perform the same, just more capacity, since someone earlier tried to do napkin bus width math implying it could perform worse. Its just using 24Gbit chips, sure they might be pushed and OCd harder since its a new revision but that wasn't my point
