M2 NVME SSD is slower on boot but faster after a restart

Saberzero · 9 July 2021 14:18

i have no idea why this is happening.

When I boot my computer while it is powered off i try and run kdiskmark:

speedonboot

Meanwhile If I just restart the PC and run kdiskmark:
speedonrestart

then when I try to run
sudo hdparm -Tt /dev/nvme0n1
I get 800 mb/s when I boot from powered off and 1600 mb/s when I restart…

I don’t know what is going on.

I tried even disabling the sata controllers (i have no sata devices even connected) and it turns the same result. I tried setting the M2 slot to use PCIE 3.0 but nothing… I went back to default BIOS settings and same problems.

My SSD is a WD_BLACK SN750 NVME SSD it has 85% free space

Give 5.12 kernel a try.

Saberzero · 9 July 2021 14:36

no change, kdiskmark and hdparm still gives the same readings

You might want to rectify your thread on Tom’s Hardware too…

tried changing bios settings and it seems if i cold boot and then enter bios first, the PCIE speed is normal (3200 mb/s)

so i tried changing bios settings and tested what the speed will be if I set the PCIE slot to work in PCIE 1.0 the speed is 800 mb/s (same as coldboot speed) and if i try PCIE 2.0 it is 1600 mb/s and then PCIE 3.0 or auto gives me 3200 mb/s.

So whenever I coldboot and don’t enter bios the speed is always 800 mb/s ( PCIE 1.0 speed), so i believe my M2 slot is only being used as PCIE 1.0 on coldboot. The only fix is to enter the bios first or do a restart. Any ideas guys?

bigStuff · 9 July 2021 15:57

There’s no “coldboot” bios is the same always. But why bother tho? Do you need access large files right away? Do you notice bad performace (and where)?

omano · 9 July 2021 16:08

Because he paid for hardware with XX characteristics, and want to have full potential of his hardware? Just my guess but the question is weird. He noticed an issue, and is looking to understand/fix it.

I was thinking about something like that but your other thread on Tom’s Hardware you said you went to BIOS and it was up to date and so on so I guessed you already checked that (//EDIT: it was in your first post here that you even said you set PCIe to gen3 actually). Also the Intel boards have Intel ME, are you up to date for that ■■■■■ Not sure how you update that, I guess you need to boot to Windows… (//EDIT: probably Windows PE is enough, it is free I think, or Hiren BootCD, things like that).

bigStuff · 9 July 2021 16:16

Asked him that, where did he notice that “issue”.

Saberzero · 9 July 2021 18:31

yup bios is up to date and I guess I will have to go to windows to update the intel ME driver and try and install a firmware update on the ssd, sucks because I don’t have another drive to copy manjaro but at least I don’t have too much important stuff, just package configs I will have to set again

going to see if I can do it with a windows live USB first I found

omano · 9 July 2021 21:41

I think any Windows live could work. WINDOWS, not Linux. I don’t know how you can update from Linux the Intel ME firmware.

Maybe that if you trust it (apparently it is known to be safe). Never used.
