My new (pre-owned) DDR3 RAM arrived today. Now my 12-y.o.
system is operating with all slots full and 32 Gb of memory.

Here is the relevant portion of the kernel boot log:

Jun 30 12:10:15 (none) kernel: Kernel compiled without mitigations, ignoring 'mitigations'; system may still be vulnerable

It's time to pop the champagne and celebrate as GNU/Linux and
only GNU/Linux breathes fantastic life into an "ancient"
machine.

This 12-y.o. and highly OPTIMIZED system will rival anything
more "modern."

Good job, Fabian!

It wasn't much of a job. Just plug 'em in and then boot
it up.

Of course, one must select a properly matched RAM set
and that's where the utility "dmidecode" comes into
play:

<https://www.nongnu.org/dmidecode/>

Dmidecode reads the BIOS which has read the actual memory
specs from the installed hardware.

Here is the relevant dmidecode output for this machine:

Memory Device
Array Handle: 0x0042
Error Information Handle: Not Provided
Total Width: 64 bits
Data Width: 64 bits
Size: 8 GiB
Form Factor: DIMM
Set: None
Locator: ChannelA-DIMM0
Bank Locator: BANK 0
Type: DDR3
Type Detail: Synchronous
Speed: 1333 MT/s
Manufacturer: 1315
Serial Number: A012B021
Asset Tag: 9876543210
Part Number: BLT8G3D1608DT1TX0.
Rank: 2
Configured Memory Speed: 1333 MT/s


I also have kept the original digital manuals that
came with this motherboard and these also indicate
a recommended memory of Crucial BLT8G3D1608DT1TX0.

Next came udm14.com (Google AI free) that led me to ebay
and the pre-owned sticks.

I have a powerful fan that blows tons of cooling air
across this naked motherboard. My CPU, memory, and hard
drives NEVER will exceed 37C and it is HEAT that destroys
components.

So what is 32GB/$(nproc)?

You need to take that into account for each gcc process
when you run make -j $(nproc).

Here I have this:

$ nproc
64

So about 4GB/processor. Good for gcc.

(The new machine has 512GB/128, so still 4GB/processor.)
