Samsung Ready with 32GB DDR4 UDIMMs for Desktops, Paving the Way for 16GB Single-Rank

Samsung is ready with a 32 GB DDR4 UDIMM (unbuffered DIMMs) targeted at desktops. Dual-channel kits with these modules could let you max out the 64 GB memory limit of today's mainstream desktop processors, and 128 GB limits of Intel's Core X HEDT processors, with quad-channel kits. AMD's Ryzen Threadripper processors are advertised to support up to 2 TB of memory (including ECC support), so it should finally be possible to pack up to 256 GB of memory on Threadripper-powered machines.

The new M378A4G43MB1-CTD DDR4 UDIMM from Samsung is, unsurprisingly, a dual-rank module (x8 / x16 Organization or up to 2 ranks per DIMM and 2DPC configuration). It ticks at DDR4-2666 at a module voltage of 1.2 V. The module itself won't be much to look at, with a green PCB and bare-naked DRAM chips. It is is currently sampling to PC OEMs. It could also be possible for more popular memory manufacturers to get in touch with Samsung for the DRAM chips that make up this module. A single-rank variant of this module could finally make it possible for AMD Ryzen AM4 machines to have 32 GB of dual-channel memory at acceptably high memory clocks.

256GB RAM, probably cost the same as a good system together

This is good, this is how the market advance and eventually products get cheaper. When 16GB DDR3 DIMMs came out for desktop prices started going down

It feels like the MB jump was much faster than the GB jump. I can remember moving from 8mb to 32mb's fairly quick and then on to 128mb. I can remember building my Pentium 100mhz with 8mb's, then Pentium II 200mhz with 32mb's (first year of college) and then building a Pentium II 400mhz with 128mb's with 2x 6.5gb drives and a Monster II 8mb daughter board graphics card and a creative awe 64 ISA sound card (End of first year of college).

EDIT: I forgot to add my blazing fast x12 CDRom to my PII 400

128MB RAM with Pentium II must have been nice.

First time i went banana with RAM was woth AthlonXP. 1.5GB on the nForce2.

I did 8MB to 512MB in 6 years, and 1GB to 16GB in over double that time. Yeah, quite the jump early on.

There's someone out there now that started with 64KB chuckling :)

Well good news but still need price drop at least for 1/2, and about the old hardware i have still P233MMX with 128MB ;)

I'm trying to remember how much Ram I had in my Thunderbird 1000mhz... I think 512mb-1gb.. but I'm leaning more to 512mb.

4mb DX2 486 -> 8mb -> 16mb
32mb P1 166 mhz -> 128 mb
P3 256 mb
P3 Dual 512mb
T-Bird 1333 512mb
1gb on my A64 s754
2gb on my s393.
4gb on my q6600
16gb on my 2700k
64 gb on my 1700.

I went from 32 to 48 megs on my Pentium Pro, man AoE2 ran so much better, lol.... Before that 384k on a Tandy 1000 ran Moon Bigs pretty smoothly though.

I thought college students were supposed to be poor.:eek:

No, AM1 was a new socket released years after AM2.

Guess I should wait on a RAM purchase. Was about to pony up for 16gb modules.. (still will, but lets see if this brings the price down).

I really hope this will help push the prices of DRAM down again. My trusty old i7-3930K with 64 GB shows its wear and needs an upgrade, buying 64 GB DDR4 now costs about three times as much as I paid 6 years ago. I was planning the next one to have at least 128 GB, support for 32GB DIMMs would be nice.

Yea, Ram is the only thing holding me back on upgrading my gaming machine.. I hope this helps lower prices.

If this comes in anywhere near the avg price per GB for dram here then it's going to cost a kidney and a right nut to buy it
32BG = $700.80NZD
64GB = $1401.60NZD
128GB = $2801.20NZD
and last but not least we have
256GB = $5606.40NZZD

But I can see them being a hole hell of a lot more expensive than that

Why in the blaze world you need so much RAM??? I have 16GB and never go 7,8GB usage in any games/apps I'm using. Are you doing multiple VMs??

Let's just say it's not while playing the Sims ;)
But yes, my VMs can easily eat ~10 GB, plus coding tools, editing tools and modeling tools, and then Chrome eats 15-20 GB if I have a lot open. If I don't keep constantly closing stuff, I will run into 64 GB in no time.
