Asrock AB350 Pro4, slow boot

Yes the DRAM frequency is 1066.8MHz so this matches up with the 2122MHz I saw in the BIOS. The memory I have is rated at 3000MHz. Network Boot PXE is indeed disabled and DVD is disabled as a boot device.

When you boot into BIOS, Main page shows up, it tells you how much memory you have which slots are populated and speed they are running at.

Sorry misread, yes I'm seeing that.

I haven't messed around with the memory speed in BIOS as wasn't sure how to do this. I believe there is a profile that's available to load that's all I know.

Hi Muziqaz,
Well the BIOS updates were what seemed to have sped things up for me and I'm anywere between 18-25 seconds. The variation? No idea! Though as already mentioned in hindsight I wish I'd stayed with the 3.40(Bridge BIOS) as this seemed a bit quicker.

The secret to getting my NVMe M.2 to show up in boot was to disconnect everything and just boot from the M2 (had already managed initially to install W10 by only having the M2 connected). Did that a few times and then reconnected my DVD & SSD and it was fine i.e. M2 finally appeared in the 'Boot' bios page.

As I haven't built a PC in over 20 years (this desktop was a second hand purchase which I dismantled and put back together, long story) this was a real learning experience. I made the mistake of buying an M2 which wasn't on ASrock's approved list though neither was the memory that had already been installed by the previous owner.

No that's not coming up. I'm sure there is a setting in the BIOS. Though I remember seeing something in the BIOS saying 2133Mhz though the memory is 3000Mhz, but I believe that's fairly common.

Regarding the 64MB DDR4 memory stick, no didn't see that?!

Okay have fully updated the BIOS in stages. Kind of wish I'd stayed with 3.40(Bridge BIOS) as this seems to have been quicker than 5.40 & 5.80 but apparently there is no going back. Prolly sped things up by about 10 seconds.

Weirdly though in the BIOS I'm not seeing my NVMe or SSD in Boot options!! Though these devices are being seen when I look at the storage config. And PC is booting up. This Asrock MB is nuts!! :(

Is memory running at intended speeds?

How do I check this?

I only had to disable other devices in the boot menu but still taking 28 secs to see a bios screen come up on my screen. And then only another 6-10 secs to get to a Windows login screen.

My BIOS is 3.2 and the upgrade path is 3.40(Bridge BIOS), then 5.40 followed by 5.80 which is as far as I can go with my current CPU. Do think it's worth upgrading?

Well the delay is happening during POST, at least it's 28 secs before anything at all comes up on my screen and I see boot options.

Many thanks

BTW no USB thumbdrives are plugged in. USB wise all I've got is keyboard, wireless mouse and a Wifi dongle.
