48 GB memory modules

[jimmypops]

Does anyone have any information on which laptops currently or will soon support these new 48GB SO-DIMMs that are starting to become available?

iv'e heard of them in desktops. But as for laptops I don't think any news has been released, too early to tell

 

see here this is pretty much all we got thus far

At least in Germany three manufacturers are offering 48GB UDIMMs so hopefully SO-DIMMs are not too far off.

In Germany we now have 48GB UDIMM from:

 

Corsair

G-Skill

Mushkin

TeamGroup

 

Still no SO-DIMM to be seen anywhere...

[1610ftw]

So it took some time but these are now scheduled to arrive next week over here:

 

 

If our pricing is any indicator it looks like US pricing should be somewhere between 140 and 150$

issue here being that laptops released before those 24/48 GB sodimms hit the market will depend on bios updates from the manufacturers to make them compatible. its not plug n play, unfortunately.

laptops released after those sodimms hit the market are more likely to support them right away.

I don't know about such a bios update being needed in all cases as I am pretty sure that I had an older MSI GT72 with a bios that predated the introduction of 32GB DDR4 and two of those sticks worked just fine in it.

 

In any case there seems to be support from at least Lenovo and MSI and probably most other manufacturers so this will be a very helpful upgrade for laptops with only two SO-DIMM slots.

My X58 platform never received a BIOS update to work with 8GB modules, or 16GB years later. I'm running 48GB now and never did a BIOS update. 

 

I'm just waiting at this point for the 48GB modules to come out then maybe I'll test them out on my laptop. If my friend wants to take my 64GB kit I'll grab a 96GB kit =D

in all these cases, were talking capacities on base of 2, i.e. 2/4/8/16/32/64 and so forth. with those 24/48 GB sticks this is not the case anymore. desktop mobos need specific bios updates to be compatible with those 24/48 GB sticks, so i dont think itll actually be easier / more compatible on laptops 🙂

48GB for sale that was supposedly tested in last years CreatorPro X17:

https://www.ebay.de/itm/305032385458

 

So there seems to be more to it (or less) as MSI pledged support without needing a bios update which would mean that backwards compatibility is better than expected:

• Feb 10, 2023

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.

the image you posted isnt shown, please check that.

 

thats good news though, lets hope this is also true for laptops and also other brands 🙂 also, the situation might be more finegrained, in that basic compability is given without bios update but higher end performance might be trickier....

I think the image was only a forum logo from TechpowerUp that did not trransfer over so I have erased it and yes we will see what will be possible.

 

From what I read with 4 sodimms and 192GB the 3600 limit should remain in effect and I am not sure if a future bios update will help with that in the laptops with that configuration.

 

If things work out that way the bigger draw imo is being able to go up to 96GB with only two sodimms and stock speeds of 5600, not that many people need more.

btw, switched to my new DDR5-8200 Teamgroup kit yesterday, now rocking 48 GB RAM, noice 🙂 Havent started tuning yet, waiting for the final bios release of Agesa 1.0.0.7b first to check and see how far i can push things mwahaha.

Apparently the 96GB (2x48GB) kit didn't need a BIOS update...1.7 was released awhile ago, we're on 1.9.0 now. At least on m18 R1

but wait, the post mentions M18 owners having trouble running 96GB ram on their machines? so its not straight forward, although the workaround seems easy enough.

 

also mentions that only 4800 mhz base speed is possible, but that might be due to higher mem density...

From what I remember anything above 64GB in a laptop was limited to 3600 MHz until now so even at 4800 we are talking about a serious speed bump!

welp, maaaybe bandwidth wise but latency should be quite worse...so depends on your applications.

I guess we will have to wait and see and you always have to compare apples to apples. Latency with 2x48 may be worse compared to 2x32 but then it may be better than previous installations with more than 64GB in a laptop which is really the point of comparison if you need more than 64GB. Currently looking at my memory usage and with a few virtual machines I am at 73 out of 128GB so I would at least need 96GB and there would be no point of going back to 64 🙂

agreed, capacity becomes a more dominant factor in these regions.

There are people including me who couldn't even get 64gb 5600mhz ram to boot without doing the power drain/reset either. 

 

My 64GB 5600Mhz is running at 5200Mhz. So the 96GB running at 4800Mhz isn't a surprise. Although, now that we have some sort of unlocked bios maybe we can change timings ourselves.

that would certainly open up tuning headroom 🙂
