G.SKILL Reveals World's First Large Capacity 256 GB (64 GB x4) DDR5 U-DIMM Memory at DDR5-6000 CL32 Overclocked Speed

[A Computer Guy]

I fail to see the need for 256 gigs of RAM on a consumer desktop platform, but I suppose it’s more of a halo product for GSkill than anything else. Then again, I suppose there ARE weird niche uses for this in SOME workloads paired with a 9950X.

It's good for VM's! 9950x + 256GB ram is awesome possibility but lack of expansion buses on AM5 really kills it.

I'd even be ok with more lane sharing like the following but nevermind board makers doing anything sensible....

x4 (NVMe for CPU)
Slot 1 = x16 (or x8[x4x4] or or x4x4[x8] or x4x4x4x4)
Slot 2 = x4 (or 8 SATA)
Slot 3 = x16 (bifurcation with 1st slot)
Slot 4 = x8 (or 2 NVMe)
Slot 5 = x8 (or 2 NVMe)

I wonder how in practice it will turn out with people being able to run those 4 dimms at that speed. It's got to be a good strain on the IMC.

Also is it crazy to have this much RAM that's not ECC?

How so? It's GSkill. They're not known for making empty product announcements.

Most motherboard makers added support for those 64GB DIMMs more than a year back and still nothing available for purchase based on those DIMMs. I wont mind upgrading to AM5 if it meant getting 128GB with just 2 DIMM slots occupied.

Ok, that's fair. That's history repeating itself. Every new RAM type always gets capacity increases as the platform matures. That's hardly "vaporware" though.

They took quite a while to finally reach retail, but there are quite some 64GB (C)UDIMMs available already. I can't see how those G Skill ones would not come to market.

I'm personally using a 4x64GB CUDIMM set from Kingston with my 9950x.

We have seen announcements of "launches" of DIMMs of that capacity for ages and nothing has been available for purchase so far(looked up and Crucial has bottom of barrel DIMMs listed for preorder/backorder so hopefully things will change). So unless these kits really are available for purchase they are vaporware at best.

What is the SKU number of that said CUDIMM with capacity of 64GB? Kingston's website doesnt seem to list them.

Bought mine from provantage as soon as they became available.

I posted a bit about some tests I did in this other thread:

Found my old 650W PSU, decided to give the system a go. Managed to boot it fine with all 4 sticks at 3200MHz.
System would not post whatsoever and instantly shut down at 4800MHz. Tried loading some random timing configs it had for Micron 2x32GB with 1.3V and set it to 4200MHz, it has been stuck in the orange DRAM light for the past 10 minutes

and nothing has been available for purchase so far(looked up and Crucial has bottom of barrel DIMMs listed for preorder/backorder so hopefully things will change). So unless these kits really are available for purchase they are vaporware at best.

Those Crucial kits have been available on Amazon for quite some time now:

Just because you can't find them doesn't mean they're "vaporware". Come on, you're more knowledgeable than that silliness.

AMD support of 256GB RAM with Phoenix mobile that was released on market in April 2023, a month delay that first intentional date. With other words 2 years on market has mainstream consumer APU that theoretically is possible to run so many RAM.

 

[_roman_]

Some more memory wasters are:

DRAM is less when you only use the graphic card from the processor, e.g. 7600X
I think I had reserved 8GiB or maybe even 16GiB DRAM to the 7600x for grahics in year 2023 when I was testing the gaming capabilities because i sold the junk MSI radeon 6800 z trio.

HMB - dram less cheap entry m2 nvme will also take up a bit of your dram.

People who use tmpfs filesystem store their files in DRAM. I use tmpfs for many years

AM5 is a consumer platform. For professional consumers you have to buy threadripper or amd milan. I highly recommend to get a server mainboard and one of those 7850€ processors. Of course you will need two of those processors, DRAM, Power supply unit, a case and fancy RGB. Kinda affordable but the way to go for more lanes. (AM5 is already too expensive on the mainboard area.)

 

[Visible Noise]

You might not need it but someone else would need it.

Consumer? Nah, don’t believe it.

Professional sure. I have a SQM Data Lake running on Oracle in-memory database server with 1.5 TB of ECC memory. Serves 350 concurrent users with < 2sec application response time.

Ram drives and VM's like crazy. Could do some wild memory-cached tiered storage. I can think of ways to use it.

Will ask my retailer if they can source those Kingston DIMMs, also Crucial kits arent available for purchase in India.

Who gives a shit if you really need them or not?

This is an enthusiast website. Half the stuff we buy we don't need.

Actually, in server space, consumer grade hardware is becoming popular.

Most server CPU's cap out at 2 ~ 3 Ghz while some server applications have simply more benefit with faster cores rather then a zillion of cores.

Lots of threading done on servers is still single threaded; take for example Mysql - large databases benefit a lot better from faster CPU's then 64 or more cores in my opinion.

256GB in a server is very common - you can cache so many things and speed up stuff so hard.

Oh, they're not available here in Brazil at all as well (as in, no 64GB model at all), I got mine during a trip to the US.

“640K ought to be enough for anybody.”

Minimum our EPYC servers come with today is 768GB, 256GB seems distant Xeon era memory.

That's just India. Maybe look elsewhere?

I could see it being pretty cool for the 9000G series (or whatever they call the next iteration of) amd desktop apu. I've been seeing lots of these Ryzen ai max +128 gb lpddr5x mini-rigs, so 256 gb with desktop power and thermals sounds like a real step-up from that. Give the igpu 192 gb of frame buffer. lots of possibilities there
