MSI Enables Support for 24 & 48 GB DDR5 DIMMs, up to 192GB RAM

Today MSI is announcing the support of 48 GB and 24 GB DDR5, non-binary memory across Intel 700 and 600 Series motherboards, including MEG, MPG, MAG, and PRO Series products. Namely, the maximum memory capacity support is increased to 192 GB for 4 DIMMs motherboards and 96 GB for 2 DIMMs motherboards. MSI has committed to providing performance and compatibility to DIY enthusiasts.

It is unnecessary to update motherboard BIOS for supporting 48 GB based memory modules. Just install the new memory module to enjoy a more efficient system with more productivity, especially for those multi-tasking gamers and users.

Do DIMMs with such sizes even exist?

It's a very new thing, but yes. Should expect to see these come to market beginning with the third wave of DDR5 ICs to be released this year.

LoL. Maybe is my problem but what is definition of waves of DDR5?

Every time some new level of performance is achieved in the same DDR generation. It's not something fixed, it's just a general feel of the current state of the market. I consider that we are currently on the second wave of DDR5 ICs, which have been gaining in density/achieving clock speeds >7000 MT/s, in comparison to the initial 4800-6000 MT/s sticks that we got when the standard released alongside Alder Lake processors.

For example: see DDR4, 2133 to 2666 MT/s in the initial samples that released alongside Haswell-E in 2014, to the current-generation 3800-4400+ MT/s chips.

Nvidia like you. They sold something with up to +60% performance with advertising of that you feels it 2.5-4 times faster because dlss 3.0 and fake frames.

That's not really a valid comparison though. Shoddy marketing aside, Ada does have some newer technologies - in this case, it's just the general maturity of the standard leading to organically improved products.

Oh yeah, I remember that all of Ada Lovelace's "locked power" can be used to collect matrices. Well, in this case, I have a sort of conspiratorial feeling that a huge stockpile of partially defective chips that don't have enough healthy cells to qualify for 64Gb has built up, and wondering what to do with those chips, now they have partially disabled blocks and so on. appeared' this half-generation, of course with a different Internet mythology molded for it. :)

thegnomeWould be nice for people not exactly needing 32gb but not really getting away with 16gb.
No, because 24GB is the smallest size, and that would mean single-channel RAM, a cardinal sin.

There's a price premium for these modules too, so the chances are high that 48GB using a pair of 24GB DIMMS is actually more expensive than many 64GB kits.

Honestly, the only place they make sense is in prosumer workstations where you're trying to squeeze more than 128GB RAM into a puny 4-slot consumer board.

WirkoOf course you'll be able to get a 48GB stick.

8 dies by 16 Gb = 16 GB stick
16 dies by 16 Gb = 32 GB stick
8 dies by 24 Gb = 24 GB stick
16 dies by 24 Gb = 48 GB stick

I'm just asking how these 32 GB (and future 48 GB) sticks are made. Are there 16 dies in 16 chip packages, without stacking? Or in 8 packages, in which case they must be stacked?
No stacking or any such thing, too expensive and not needed. Just plain old higher density memory dies and more of them (i.e. dual side dimms)

While that too is possible, the industry did announce 24-gigabit dies back in 2021. They were aware that 32-gigabit dies would take more time to develop so an intermediate step made sense.

In the case of RAM, larger dies can't replace denser dies. They wouldn't fit on the DIMM. Ten in a row need to fit on the module because chips are designed for server modules. Consumer DIMMs with eight chips in a row and some space between are just a byproduct.

The EggYeah....but then you have to use an MSI motherboard.
my MSI MAG B550 Tomahawk is by far the best board i ever used, in the category bang for bucks and in the "feature rich" for the category ... not a single F up with it since i installed her in my current build ... :laugh:
(i guess i am overly lucky with hardware... aside with Razer tho, long story )

48 GB and they are speaking about “gamers” ? This is really marketing BS…
I can barely justify 32 GB for gaming.

WirkoThis must be some TLC black magic, or how else do they put three bits where there should be two.
This is DRAM, not NAND... there's no SLC, MLC, TLC or QLC here

Pretty useless for desktop, what use case needs that much ram?

Could definitely be useful for workstations if threadripper 7000 supports such modules. Even 384GB not enough.

My thoughts exactly... A year or two ago I went to 32GB only because I needed another memory kit and 32GB was so damn cheap. I grabbed a 2x16GB kit for my rig and passed my old 2x8GB to my wife's new machine.

I know of some people who will disagree with you. They want more ram memory but they are limited on what out in the market atm.

On desktop? What are they doing out of interest?

For Servers and Workstations I can definitely see the need.

Aquinus48GB in a single unregistered and unbuffered DIMM. What a time to be alive!
"hmm, i think one of my RAM is causing BSOD. Gonna run a quick 23 days 1 pass to check it."

Hi,
Someone hit the lottery or something for this much memory :eek:

Some of them do heavy video editing, and the other does something of modeling work, he explained to me but it went in and out of my ears.

well, modelling and heavy video editing aren't exactly "typical desktop usage".
