Fireduck
turns out I am an idiot
2018-11-30 02:27:41
Fireduck
I had a motherboard that I thought was bad, for the life of me I couldn't get video out of it
2018-11-30 02:28:10
Fireduck
I ended up getting it booting by putting linux on the m.2 drive, putting it in, letting it boot, recording the logs to see what network drivers it needed
2018-11-30 02:28:19
Fireduck
moving drive to other system to examine logs and set it up
2018-11-30 02:28:29
Fireduck
anyways, get it working but it was always a bit flakey
2018-11-30 02:28:37
Fireduck
so I today replace the motherboard
2018-11-30 02:28:40
Fireduck
no video again
2018-11-30 02:28:49
Fireduck
turns out that cpu doesn't have video built in

umarucchi
ahahahhahah

nvme @ 13k/s on windows 10 with arktika, any idea why so slow
2018-11-30 17:46:49
Fable
its a z270 board, does the m.2 slot need x4 bandwidth?
2018-11-30 17:47:24
Rotonen
yes
2018-11-30 17:57:50
Rotonen
the whole story of how the physical slots map to whatever is messy
2018-11-30 17:58:17
Rotonen
always refer to the motherboard block diagram
2018-11-30 17:58:43
Rotonen
you’ll also want it directly on the cpu
2018-11-30 18:23:05
Fable
directly on the cpu?
2018-11-30 18:23:13
Fable
you mean on the motherboard?
2018-11-30 18:24:30
Fable
I was thinking that it was because you needed ram to go with the NVME to get the full speed so 2 file layers could be used
2018-11-30 18:24:40
Fable
but reading back apparently its not needed
2018-11-30 20:09:07
Rotonen
i mean what backs up that bit of the pci-e stack
2018-11-30 20:09:49
Rotonen
mining motherboards are not great for snowblossom
2018-11-30 21:31:11
Fable
its not a mining motherboard
2018-11-30 21:31:29
Fable
Im not sure what you mean by the bit of the pci-e stack
2018-11-30 22:07:38
Fable
I have tried both m.2 slots
2018-11-30 22:08:00
Fable
I guess RAM is needed to work with the nvme
2018-11-30 22:08:04
Fireduck
what are the m.2 devices themselves?
2018-11-30 22:08:11
Fable
samsung 970 pro
2018-11-30 22:08:15
Fireduck
which size?
2018-11-30 22:08:32
Fable
only getting 14k/s
2018-11-30 22:08:48
Fireduck
https://www.storagereview.com/samsung_ssd_970_pro_review, should have 370k/s random reads Samsung Electronics America, Inc. announced the third generation of its popular M.2 NVMe SSDs. Again releasing a high-performing 970 PRO and a higher capacity 970 EVO. As with previous versions, the 970 is pushing performance levels even higher with quote speeds of 3.5GB/s read, 2.7GB/s write, and up to 500K IOPS in both read and write. This level of performance is ideal for prosumers and tech enthusiasts as well as those that work with 3D, 4K graphics work, high-end games and data analytics.
2018-11-30 22:09:02
Fireduck
so should be 60kh/s
2018-11-30 22:09:10
Fireduck
(just divide by 6)
2018-11-30 22:09:17
Fable
okay, its no where near that. I have tried on 4 machines
2018-11-30 22:09:21
Fireduck
Is the CPU maxed out?
2018-11-30 22:09:24
Fable
no I benched it'
2018-11-30 22:09:27
Fable
250k/s
2018-11-30 22:09:57
Fireduck
yeah, I had one of those, I think that exact one and only found it worked at full speed on some boards
2018-11-30 22:10:05
Fireduck
never got good performance with a pci.e m.2 card
2018-11-30 22:10:09
Fable
Yeah I think its the board
2018-11-30 22:10:20
Fireduck
also, how many threads are you running?
2018-11-30 22:10:29
Fireduck
have you tried higher?
2018-11-30 22:10:43
Fireduck
you need a lot to get the queue full and always have IO to do
2018-11-30 22:10:47
Fireduck
maybe 256
2018-11-30 22:11:01
Fable
Yeah I have tried 512
2018-11-30 22:11:05
Fable
and 256
2018-11-30 22:11:18
Rotonen
sometimes the optimal thread count peaks are narrow
2018-11-30 22:11:19
Fable
I really think its just the motherboard architecture
2018-11-30 22:11:32
Rotonen
given your description, sounds plausible
2018-11-30 22:11:38
Fireduck
it is basically all crazy
2018-11-30 22:14:32
Fable
even has the heatsink
