Ok Guys & Gals

Time to start ponying up those nickels & dimes for mem sticks for our servers come 2015!!

I don't buy computers, I build them!!

Given that 32GB DDR3 dimms are around $1000 I don't even want to think about how much one of those would cost. Let alone 4 of them for a quad channel kit.

It's my understanding that the memory industry has been ready for DDR4 for a few years now, and have simply been waiting for chipset implementation to drive demand. What that means to me is that this availability should drive costs down quickly.

Speaking up DDR4 chipset support, it looks like Intel will finally be including support in their upcoming high-end Core i7/Xeon CPUs later this year or early next year.

Exciting times! :) And I can still remember paying $100 for a 4MB 30-pin SIMM that had to be installed in quads. Each 30pin SIMM was 8bits wide, so you needed 4 to match the 32bit bus of the 386/486 era, meaning that a memory upgrade from 4x 1MB chips to 4x 4MB chips (16MB total upgrade) cost $400, which at that time was really expensive. And I'm sure many people here can recall similar steep prices for RAM even further back than the 30-pin SIMM days.

I´m sure there are some around who remember when we paid about US$ 700 for a QuadRam Board with 320Kb (yes KB not MB) for the first IBM-PC wich comes with a full 64kB, a lot memory at that time (the avaible compilers at that time could only use 128kb at most), before even the XT era.

Ah yes, the QuadRam boards. Didn't they use DIP-20 DRAM packages?

Speaking of compilers from that era, it is my understanding that since the original Intel 8088/8086 were source-code compatible with it's own Intel 8080 chip, which could only address 64 kilobytes of memory, so all memory accesses had to be done in segmet:offset form in 64K chunks to address the full 1 megabyte of memory possible on the 8088/8086 series. Even the 80186/80286 series chips still had this limitation! It wasn't until the 80386 series chips that addressed memory in a "flat" 32bit protected mode that all of this went away, allowing programmers full access to large amounts of memory for newer applications, will still working with binaries compiled for the 8088/8086 in segment:offset form.

:)

Sorry, didn't mean to derail the topic. I just love old x86 stuff!

Yes the 64Kb DIP-20 DRAM, you need 8 to get a working 64kB RAM... i miss them...

The first Basic compiler i received for testing has the limitation of 64Kb of data and 64kB of program itselfs, after that the "bigger" RAM compilers who could use different segments of 64kb each apears.

But we do a lot of work with this "vast quantity of RAM" at that time and some projects from that era still working today after more than 30 years.

$1,000 for a 32MB RAM module.

"At that time"??? For some of us it still is!

Indeed! Though as a technology enthusiast, I'm not really keen on all this cloud stuff, or social media for that matter. ;-)

@Grant: Yeah, buying 4x 16MB modules (the next step up from 4MB in the 30-pin SIMM era), each 16MB model was $400, making the total upgrade cost $1600! I was fine with my 16MB total until Windows 95 came out and my 486 was really bogged down by some of the software. I wanted to upgrade to 4x 16MB but my motherboard couldn't handle the higher density chips.

And of course going back to the original topic, the S@H servers wouldn't be able to handle the 128GB DDR4 modules...

I had an Atari 600XL w/64K inside the computer case and that only needed 2 chips.

Times certainly have changed, 32GB dimms, I'm only up to four 4GB Dimms.

Here's an idea...someone ask Eric to post an *official* list of the most urgently needed items?

I thought they were doing that with the GPU Users group & their donation page.

I donated a fortnight ago; they made their goal quickly and took the page down. BTW where is my star to go along with my badge?
