I came upon a post containing this.
I have a System with 1.25 TB of ram the Mother board sees it , lshw see's it , but only 1.0 TB is useable, Is there a kernel Parameter I need to recognize more memory ?
I did not know that computers has that much capacity.
What apps could use that?
I think that some sever motherboards support 1 Tera Bytes of RAM, it's probably useful for that
Thanks.

64 bit 3d Cg apps, might be enough to contain 3d photorealistic world the size of skyrim
Server running webshop which contains for example lots of images,independent of its hires images of real clothes or other things would benefit greatly
Wonder if hutch gonna build such computer?
Interesting.
Certainly not going to hit the shelves of big box stores any time soon. Sounds more like a custom build for very heavy number crunching, encryption/decryption, etc., or perhaps video rendering. Sounds like something that NASA or NSA would need. A bit much for most users.
Funny thing is, that someone, somewhere would still complain that they still need more memory than that. And a ginormous amount of hard drive space to go along with it. :tongue:
Edit to add... quantum computing could be another application that needs that much??? Ultra fast DNA sequencing? Ok, now I'm going off the rails. :biggrin:
Zedd ,i sometimes like make 3d animation
But my own 3d models are lowpoly
And used to make tiny asm programs you can get away with older computer with less ram
Check my 203 byte .com file in dos forum
I only used fibonnaci bcd using 3.5gb memory :
Possible add ca 2 billion digits number with second ca 2 billion digits number
Most of the Xeon E5 ... v3 series CPUs will address up to 768 megbytes of memory if you have the right server boards and ECC memory so I imagine with much later Xeon CPUs (gold and silver) and the right boards and memory, doing over 1tb of memory is possible but you sure would not want to pay for it.
Think of the joys of a rack mounted server roaring away while handling some massive number of network connections with CPU capacity to spare and making so much racket that you would end up in the loonie bin at you local "Funny Farm" (where life is beautiful all the time).
There is good reason why these things get stuck into an air conditioned room well away from users. Users like Amazon come to mind.
It did not occur to me how much heat they generate.
I remember in college taking my punched cards down to a computer room below ground where the temp was freezing.

Guess what, my rusty old Core i5 addresses 4096 megbytes of memory in 32-bit mode :cool:
I wonder how long it would take do comprehensive memory check on 1 TB of RAM, it would takes days at least.

I expect such mobo having much more than quad channel memory and support fastest memory stick DDR x ,x being newest memory generation
Hutch when server farm investment goes wrong is why they need to sack 10k employees to keep afford loan rent + afford huge electricity bill here in europe ?
Because webshops must run 24/7 ,while ordinary highend computer user can restrict usage to hours at home and avoid games that runs cpu,gpu,hd at max power consumption

A bit out of my allowable price range. :tongue:
In theory with that much memory, wouldn't need a hard drive? (For home user)
With creative techniques, would that even be possible? (OS plus all other contents of C: drive loaded into RAM for instance)

1.25 Tb RAM is not abnormal when you have a lot of virtualized servers hosted by a system like Vmware.
Zedd newest ms flight simulator with many tb terrain data benefits from tb ram
Or modern game with many gb content+ extra downloadable content

Nobody buys such things in the store, you need to look for used ones. If you buy in parts and you will do it all the time, you can buy 4 terabytes for 4000 euros.

That's more within reach for the well-to-do hobbyist. :biggrin: But still too pricey for me. :undecided:
:tongue:

Erol hit it on the head, run a BIG server with an Intel Gold Xeon (or the server sized CPU from AMD) and install a couple of terabytes of ECC memory and you could be a tiny fraction of the size of Amazon's server farm.
Forget running it on Windows, install the right flavour of UNIX, the CPU will cost you 10 grand or up and a couple of terabytes of ECC will cost you some rediculous sum of money so if you are loaded and want to build a middle sized server, have a ton of fun. :tongue:
On my Windows 64 bit boxes, I run 64 gig on 4 of them and my Apache server Windows box has 32 gig of memory. which is more than enough for what it does. (recycled from my ancient i7 box that spat 1 out of 8 SIMMS) so I used 4 of the remaining SIMMS in the Apache server box.
My ancient i7 box rebuilt with a 14 core Xeon (plugged into the same socket) got a new 64 gig of 3200 memory as I could not routinely buy the 2100 that the 14 core Xeon tops out at.
The idea with memory with a 64 bit Windows box is to have slightly more than enough and adding more does nothing for you. If your board supports it, ALWAYS set it up with 4 channel memory as it solves any problem with memory speed.
Hutch, I wish to set up a server which has less requirements than terabytes of ram
Instead of server that compile cpp for you,asm assembly on a server
Both uncompressed images and uncompressed movies i use because of later postwork them
I got tired of delete files from my newer tablet
It showed red and few 100mb when connected to pc, so i got 32gb external microsd card (20 euro ) and installed today
And started to transfer many folders to external card
Older android devices is useful to invest in external micro sd card as long you stick to max size the old device can handle , if 128gb is max its a waste to buy bigger
Newer Android phones samsung move to internal 1024gb, without external micro sd slot, Android os changed to stop apps stored in external micro sd because security risk, so multimedia backup only
