I have my new 20A circuits
now I can put everything in one room again
of course I bashed my 256gb node into a door while carrying it and now it is slow
so...winning?
just plopped some of the ram off the slots? :stuck_out_tongue:
checked that, they still all show up
all processors online?
all processors seem to be
now, you've managed a funny
yeah...might be network cable is sad
testing local memory access
also, get a cart
local memory access is 100GB/s+
wheels make life nicer
so seems cpu and memory intact
cart wouldn't help, there were stairs
ok, going to jigger network cables
wonderful things, but no idea why amazon does not have models with pneumatic wheels
also if you ever get one, make sure it folds flat, as otherwise trying to fit it into a car trunk is quite the tetris
wouldn't dmesg actually tell you if the ethernet level handshake went wrong or if there are excessive packet tranceive errors?
or alternatively just looking at netstats
(dunno if you munin or equivalent for that)
netstat and ifconfig look fine
nothing in dmesg
10g network, no errors
so it's just pouting at you
is the hardware new enough to tell you via dmesg if it gets thermally throttled?
you could have bumped the heatsinks off kilter
they're relatively heavy pieces of metal, usually attached by plastic rivets or somesuch on servers
I can read at full speed locally, so I don't think that is the problem
fair enough
it seems like networking somehow
going to reboot and see if that fixes it
do you have multiple phases for the AC? and you're not doing anything silly like plugging things in inappropriately cross-phase?
also, are all the things on the networks grounded to the same thing?
Heh, of course I am doing that
Same ground but different hot
I wonder if 10G network copper card needs special cabling
there are lots of different 10G network standards
for rj45-based usually cat5e is enough
standard says cat6
Cat 7 is what I have
short draws are probably fine on 8 wire hangers
cat 7 is plenty
shielded cabling can be a thing
or crossing a power line at a 90 degree angle
ok, 86MB/s over network on 1g
so maybe cable or interference
ok, now getting 145MB/s on 10g
porcelaine risers to the rescue? :P
I just rebooted it
and moved some wires
the usual change multiple things and then don't know what had an effect
i am assuming the plumet in hashrate to support my end of month bill arrival hypothesis
hardware is king
do you think this is cloud mining?
i do
haha
ASRock is now on my shitlist
But they can never replace Biostar
Biostar, literal destroyer of hard drives
asrock’s been on my shitlist since 2007
i was annoying when intel stopped doing motherboards after sandy bridge
yeah...I should have stuck with my standards for inexpensive brands, Asus and Gigabyte
but, supermicro does good stuff
gigabyte i’m ambivalent about, but asus i use and msi seems to work
asus tuf is good stuff
second block in a week, unheard of
ha, I noticed
well, you do have about a permille of the nethash currently
i’m still not fully getting how the share falloff works
I think there is something about PPLNS that makes it hard to describe with words
i get stuck on ’n’
n=5
the top address still has the same share count as it had before the past 5 blocks and it’s not participated any in the past 5 blocks
some of the addresses with lesser share counts have had some small chip-offs in the same time span
there’s some whole dynamic i’m missing
if the difficulty is in general increasing, that will increase the look back pool
and the number of blocks the pool actually finds is irrelevant to the calculation
so still in the process of (slowly) figuring out the n
@Rotonen I think it means 5 blocks worth of shares.
I think it means they average your shares across 5 blocks and pay you based on that. It rewards people that have been there longer first, new people will see smaller payments, at first (because their average isn't up)
ok, I have a high priority trouble ticket to reduce the noise of that Dell R900
I wonder if I can swap out those fans
your ram server? @Fireduck noctua fans are the way to go, but they push less air.
yep
from what I have read, the headers are strange and if you don't get them wired the way the system expects it is going to refuse to boot
plus my problem might actually be small fans in the PSUs
which probably won't be easy to get to
I think this thing is going back in its hold
hole
but fortunately, with its new 64gb sidekick, it doesn't need 10g networking
I don't have 10g networking to the hole
i was semi surprised it took this long :D
I only pulled it out last night
there are two standards for server fan headers as far as I know, noctua supports them
any picture you post showcases lack of wall bulk
as for the PSU fan, depends.
THUNDER!!!!
THUNDER!
I haven't heard thunder in so long.
you can usually solder in a resistor
yeah, we don't get that here a lot
my bike ride home might be fun in the dwarf fortress sense
i think we can safely assume there are three header options, Standard A, Standard B, and whatever the fuck Dell does here
usually fans have POWER and a DATA line
Right, and the data is usually PWM
if you just connect the noctua power it'll run full speed (and they come with adapters that can lower the speed)
on Dell it is probably morse
I basically barely have time to run down there and throw some hardware on the shelf
screwing with soldering pins on headers I don't have time for
