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).

Am 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?

you get slightly more ram than 32 - but at the same speed as 32gb kits... so it is kind of nice to get like 7200 48GB kits for lower price than the 64GB ones when you don't need 64 but do run some VMs and crap in the background that take up space (ahem chrome).

But why though? The bus is a binary (2x32bit per channel) one, so what is the advantage of these modules?

Sure, it appears to work, but that just seems like additional unnecessary complexity.

Yeah I cant wait for the reviews to see how these actually perform.

Customer choice.

"Non binary"

Is this memory for quantum computers? Analog computers? Or it is actually binary memory but nobody seems to understand what powers of two are or aren't?

Ah yes, the dichotomy between choice and confusion.

I can't wait for people to wonder why their computer doesn't work when they got a 32+16 kit instead of 24+24 and try to enable XMP or EXPO.

Non-binary capacities. OP probably could have been a little more clear.

It has nothing to do with the bus. As memory capacities increase it's necessary to come up with more dense chips (with more capacity per chip), DDR4 used chips with 8 gigabits per little die (which x8 - or x9 for ecc - makes the 8 gigabytes we're used to) with 16 gigabit being developed more recently. The idea going around is that 32 gigabit chips weren't able to meet performance/yield/whatever targets so 24 gigabit chips are being used for the moment

They don't identify as 32GB or 64GB, that's all that means.

I've never seen anyone call the 24 and 48GB of RAM that you could install on an x58 i7 system "non binary", because it's wrong. We shouldn't normalize it, RAM is still binary as long as it works as currently does.

I think it's just a lame attempt at clickbait and controversy trying to connect a topic with current culture wars

That was due to triple channel memory. This is per channel.

Huh? G.SKILL already have 24GB DIMMs for sale. If the big leak news is that these will be EXPO, that isn't worthy of news. 24GB XMP DIMMs work on Ryzen already.
phanbueyYeah I cant wait for the reviews to see how these actually perform.
I can tell you right now that 24GB perform worse because the sub-timings are higher vs 32GB and 16GB DIMMs. I've been bad and haven't finished my 5600 and 7200 reviews that use 2x24 GB.

Exactly what I was thinking.. you can go and buy G.Skill 2x24GB DDR5 right now.. Up to DDR5-8200 (www.gskill.com/community/1502239313/1680255692/G.SKILL-Announces-New-24GB-&-48GB-Module-Capacity-Kits,-Up-to-DDR5-8200)!

The only news here must be EXPO..

@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.

Count von SchwalbeThat was due to triple channel memory. This is per channel.
But he is right calling the kits non-binary is beyond silly, had me scratching my head as it was just a couple months ago it was announced that quantum memory was on the distant horizon as the result from some research being done, (stored values being: 1, 0, indeterminate). Article title had me thinking it was that and shocked that it became a reality that quickly but nope it's just non-standard memory capacities.

Exactly.

And I've seen suspiciously few announcements or news lately - none, to be exact - about those 32-gigabit dies. As if they were still far from feasible with current technology.
Count von SchwalbeSure, it appears to work, but that just seems like additional unnecessary complexity.
Complexity? The Sinclair ZX Spectrum home computer had 48 kilobytes of DRAM in 1982. The Commodore VIC-20 had 5 kilobytes in 1981. The MMUs and memory controllers in modern processors can do infinitely more complex things than use 3*2^n bytes of memory, and I'm sure they could as well use 47.5 GB or 49.25 GB modules to full capacity ... A 24 GB or 48 GB module only seems "complex", that is, not working, if BIOS has not been taught to recognise it.

It'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.

Do you have 48GB Expo kits(Gskill already is selling those) for review? interested to see how those perform.

I don't, only XMP ones. It's practically the same though. Also I see GSKIL is already selling these EXPO kits in the news article on Newegg.

Maybe that these "new" ones will be Micron ICs instead of Hynix? The GKILL 7200 2x24GB kit I have is Hynix and the Corsair is SpecTek (aka the rejected ICs from Micron). Both have been on sale for 2 months now. Still confused what makes this news worthy.

48GB and 24GB sub 6000 are listed as Spectek B on Gigabyte's QVL while those above 6000 are based on Hynix M chips. Thats why I was wondering how those Micron based kits compare to Hynix.

Only done the preliminaries with the GSKILL Hynix ones. They too have higher sub-timings compared to 16GB DIMMs. At those higher speeds the primary timings are higher as well. These 24GB DIMMS are good for those who still want to be using single-channel memory but absolutely need more than 32GB.

Edit: I don't have a apples to apples comparison. of Hynix and Micron retail kits at the same frequency. Downclocking the higher end or overclocking the lower kit is easy to match the primary, but the sub-timings are unknown. I need a kit in hand to know what they are. Otherwise its whatever timings are from the XMP/EXPO profile for that specific bin and will skew the results to find out if Hynix or Micron 24 DIMMS are better. I will say Hynix 24GB I have can easily do 8200 while, Micron won't pass 7000 overclocked.

Here is my Hwbot submission for 8000 hwbot.org/submission/5292023_ and 7000 for Micron hwbot.org/submission/5233079_
