Mega Memory: Crucial Introduces Massive 128GB LRDIMMs

Traditional registered DIMMs connect to the parallel memory bus that attaches to the DRAM controller aboard Intel and AMD processors. LRDIMMs (Load Reduced DIMMs), in contrast, have a memory buffer chip that serves as the connection point for the CPU’s onboard memory controller.

Dell notes that LRDIMMs greatly reduce the electrical load placed on the CPU per-DIMM slot, and therefore allow much larger memory configurations.

If this is the case I think mobile devices such as laptops and 2in1 computers shpuld be moving soon towards this. This would be a huge bump in performance as majority of the thin and light laptops max out at 8 or 16gb of memory

prices on these DIMMs — currently an eye-watering $3,999 each on Crucial’s site — speaks to the economics of deploying the manufacturing technique.

These sticks do cost a fortune but as time passes and the world wide shortage of sillicon passes away this could be trickled down to actually being used in consumer devices.

We don’t expect to see consumer memory loads in such eye-popping configurations any time soon, but it’s interesting to see the technology rolling out in servers.

i do agree to that. lets wait for 5 more years and see where technology takes us.

[PlayStation 2]

Yeah, this doesn't seem to fit the guidelines for news articles.

[titan384]

I'm sorry. I will go read the guidelines right away.

[GDRRiley]

need your opinion.

Can't wait for the Corsair Vengeance counterparts. With RGB maybe (\/) (;,,;) (\/) ?

Since LR = load reduced = onboard memory controller = faster memory in servers.

nothing is acceptable without RGB in 2017. 

Max RGB FTW!

You don't get  lower power consumption with this. You still have the same number of chips and you also have a potentially power hungry "buffer chip" on the memory stick as well.

The 128 GB stick uses 16 memory chips and each of those is 8 GB in size, but each chip is practically done using 4 2GB dies stacked one on top of the other, so each of these 8 GB chips produces as much as 4 classical chips. 

If your regular 8GB memory stick with 8 memory chips uses let's say 3w, then this one would use maybe 15-20 watts just for the memory chips, plus maybe 1-2 watts for the buffer chip... so if your laptop averages 40-60w power consumption, would you really want to add extra 15-20w in memory, to cut your battery power in half ?

At least add some heatsinks. Asus dual socket ws uses them, and green pcb ruins the color scheme. 

[mariushm]

No need, they're server sticks. 1U and 2U servers would have a row of high power fans blowing air from the front of the server to the back, and they may even have a "tunnel" to direct air flow through / over the memory slots and cool them through forced air cooling.

i understand what you are saying. and i do agree with your point in current scenario. but 5 years down the road i think there would be a way to minimize power consumption and there will be better battery technology to support this kind of stuff.

 

when i got my first laptop in 2005/2006 it was a compaq presario v5201tu. it came with 256mb ram, celeron m 410 1.46ghz single core cpu and 40gb hdd. the battery lasted nothing more than 45mins to 1hr. 

the second laptop in 2012 i got was sony vaio svs15125cn with 2.5ghz i5-32xx with hyperthreading, 8gb ram and faster hdd and a dGPU.  its battery lasted around 3 hrs. 

 

with advancing technology we have been able to get better performance with improved energy efficiency. so according to me hoping this technology to trickle down to mobile technology is not something which is unachieveable.

[AlTech]

Yay . Now we need 256GB and 512GB options with a 1TB option by 2020 .

[Matu20]

Holy fuck, that's more than I have ever had combined.

[Doobeedoo]

Quite alot of memory on one stick. I'm sure it will help RAM prices. 

[bcredeur97]

it's amazing how far memory has come in the last few years.
