what sort of use cases/memory_needs/etc (was RE: Warranty!!?!?!?!?!)

Wed Sep 6 19:33:16 MST 2017

I had 32gb until a year ago or so, and my system would trip out over
nothing. but my normal use, but I'm not normal  Looking at it like a
network with ~50% utilization, I figured 64gb ram would be a stopgap, and
128 probably more what I want, so let ebay sniping commense.  Linux is
pretty damn robust when the DE isn't crapping on itself, or the graphics.

I've mentioned the laptop, but the desktop is a 2x cpu dell precision 7910t
had from ebay, I stacked in some E5-2630 v4 cpus (20 core, 40ht/ea), some
8x samsung ddr4 ecc sticks, an nvidia 1070 gts, and a pair off samsung 950
512gb in raid1 (960 was like a month out, meh) ssd m.2 drives on dual pci
carriers to the 8x bus.  I don't want now, linux does not stop, just the
DE.  Prior whole sys would crash with usage about once every 2 weeks.
Cinnamon poops out about once a month, but I just hup it.  It's more
compositing/gpu shite that still can't cope.

[mb at desktop ~]$ uptime
 19:22:01 up 97 days, 10:11,  8 users,  load average: 1.53, 1.21, 1.15

## as of now

Last config, i7-4760k, 32gb ddr3 would crap out, and often.  I blame kde
mostly, why I use cinnamon now.  Not perfect, but more stable.  Fsck
compositing, I can deal without, really, but they won't let me.

YMMV, as they say.
