New DDR5 technology much faster than DDR4 or other DDR5 options

Wow and 512GB...who would ever need that much memory? :)
The less you need, the more you have. JaxCoder.com
With 64GB, I don't feel that even my old i7-4800K is too slow to run multiple VMs simultaneously; rather, I always find myself limited by RAM/disk/network. With 512GB, I suppose I could then run so many VMs that the CPU would finally start to get too slow to be practical.

I thought when I upgraded my machine to 32GB that I would finally have enough but like you say if you start running VMs they eat it up quick. Plus the more memory you have the more the applications that you run use. (Moore's law or something?) I've got an older processor but it's still relevant as there hasn't been a lot of progress in that are for some time, except for the number of cores.

So - how does this affect the box I'm remoting in from it at this very moment - bulging with 8GB of DDR2 ?

New superfast DDR5 memory technology from Samsung. Samsung's new DDR5 memory more than doubles the speed of DDR4[^]
Get me coffee and no one gets hurt!

512GB? of DDR5?? Yes plz.

My gaming PC needs a faster RAM. But more then that, it needs a better GPU :(

You should burn Welsh coal in that machine and it will go faster, thats what the Fat controller says.
Well - it came with a video card for HDMI and plugs right into a 55" 'monitor'. It's doing rather well in its later years - and what would it do if it had more than two cores @3GHz? For now, it just has to settle with giving orders that are obediently obeyed by a Xeon with 32GB RAM @3.5 GHz. What have you got in your wallet ?

Scientific application. I work with chemists that create 10s of GB sized files, then want to massage it every which say, including graphing and tables. It would be much quicker to keep all that data in memory.

There are better processors out there than Intel. Motorola 68000 was one of them. I haven't heard if they came out with a 64 bit processor.

The new 640KB? :)

So, I always thought after the 640K debacle. And PART of that was ISOLATING the memory above it to 1MB for the O/S. And I thought... How stupid, you just created a hole in memory when we go above that. And we did! But now, windows 10 has a feature for a restore partition on our hard drives. Instead of allocating it and forcibly leaving space BEFORE the drive partition we would like to expand. THEY, OF COURSE, put it at the end of the disk. So, when you go to upgrade the drive, you have to play Partition Games, to move the partition to the end of the disk and expand the one you need more space on. Is it me... Or do we KEEP CREATING the same problems, over and over?

It's not just you. There are at least two causes for this: 1. Companies prefer to hire young engineers out of a false perception that they are (a) cheaper and (b) have more "commitment". 2. Said engineers have learnt all the latest stuff in university or college. They all know what is supposed to work. What they haven't internalised is the difference between theory and practice - not all ideas that work in theory necessarily work in practice.

Experience Matters. But I also blame managers. I had a manager in t he 1980s who taught me a lot. But we were struggling to get the batch process that should finish over the weekend to finish my Monday Night/Tuesday Morning. One OLD (and long gone) developer, wrote a faster version of the update programs. It was a 2 pass system, once would read a tape, and merge with the file, the other would loop over and rebuild all of the handmade index files for fast searching. One problem was that errors on the tape caused corruption, which caused us to restore the master file, which took the ONLY tape drive off line. I had a different idea. One pass. Write an entire new set of files. Completely restartable without a restore, and the resulting "new" files were being created while tape access was relatively slow anyways. It simply required enough free space for one extra master file (which, we had). On the back of the envelope, I calculated that this this reduces "reads" by at least 2. The second week, the master file would be in the same order as the tape (which removed a need for an index file, I was forced to keep), and the sequential read of that file would be much faster. The manager REALLY WANTED me to fix the OLD 2-pass version, so they did not have to claim the loss of investment???? (Sunk Cost Anyone???) I was a teenager still, and without his blessing, I stayed late, 1-2 hrs every night, and worked on weekends to write the first version of this... It was MORE than 2 times faster. Especially with the new sort. We were finishing on Saturday nights, or Sunday Eve... No more Mondays (in the end)... The reward, when I showed him the beta version/Proof of concept. they TOOK the project from me, and handed it to a less competent developer who crippled the speed, and I had to save it. Get it online, and PREVENTED them from taking it away, until they ACKNOWLEDGED the benefits! My Reward, No bonus, and a tiny raise less than COLA... The excuse "you were not a good team player! And we did not get ALL of the benefits you said" (using my absolute best case, not the base case). So, SOMETIMES... It's Management. In 2+ years, I learned a CAREERS worth!

Incompetence can be found at all ages, and in all professions. My point was that part of the problem is the loss of "institutional memory" caused by preferring young hotshots to older people who have been round the block. This is not to say that the young hotshots are not, at times, right!
