turns out I am an idiot
I had a motherboard that I thought was bad, for the life of me I couldn't get video out of it
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
moving drive to other system to examine logs and set it up
anyways, get it working but it was always a bit flakey
so I today replace the motherboard
no video again
turns out that cpu doesn't have video built in
ahahahhahah
nvme @ 13k/s on windows 10 with arktika, any idea why so slow
its a z270 board, does the m.2 slot need x4 bandwidth?
yes
the whole story of how the physical slots map to whatever is messy
always refer to the motherboard block diagram
you’ll also want it directly on the cpu
directly on the cpu?
you mean on the motherboard?
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
but reading back apparently its not needed
i mean what backs up that bit of the pci-e stack
mining motherboards are not great for snowblossom
its not a mining motherboard
Im not sure what you mean by the bit of the pci-e stack
I have tried both m.2 slots
I guess RAM is needed to work with the nvme
what are the m.2 devices themselves?
samsung 970 pro
which size?
only getting 14k/s
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.
so should be 60kh/s
(just divide by 6)
okay, its no where near that. I have tried on 4 machines
Is the CPU maxed out?
no I benched it'
250k/s
yeah, I had one of those, I think that exact one and only found it worked at full speed on some boards
never got good performance with a pci.e m.2 card
Yeah I think its the board
also, how many threads are you running?
have you tried higher?
you need a lot to get the queue full and always have IO to do
maybe 256
Yeah I have tried 512
and 256
sometimes the optimal thread count peaks are narrow
I really think its just the motherboard architecture
given your description, sounds plausible
it is basically all crazy
even has the heatsink
