i5-4570T + 7i76e

Hello,

I’m looking at buying a Lenovo Thinkcentre M93p as a computer for my 7i76E.
is this a good combo?

Intel i5-4570T 2,90 gHz, 4 GB DDR3 ram, 120 GB SSD

Thanks in advance!

I have one of those running a machine daily, but with an i7 4770 i think, it is at a clients site for over a year.

Do keep in mind that if mine worked, yours might not, there are a lot of things inside a PC that can mess up latency, most of them can be fixed, but not all.

Oke cool, yes I understand it’s never 100% comparable… just wanted to check if the CPU was a go or not

I ended up buying 2 Lenovo Tiny PC's... 1 with i5-4570T and 1 with i3-6100T. I want to test them both with LinuxCNC.

What is the adviced Kernel for the 7i76E... Just Debian 10 PREEMPT?

Official ISO from the downloads page, so yes, Debian 10 with Preempt-rt kernel.

I downloaded the original ISO, copied it on a USB drive via Rufus… but I’m having trouble installing it, on both systems.

The first problem was it wasn’t able to detect the ‘cd-rom drive’, I fixed that with:
mount -t vfat /dev/sdb /cdrom

Then I have problem with partitions part of the install, it gives an error.
Something with vfat SCSI1 partiton connecting to /boot/efi

I can’t figure out what the problem is…

Last time I installed Debian 10 I didn’t have problems at all (on an old PC)

Disable secure boot in BIOS, and maybe also set the boot to legacy mode.
F@#$%#^#$ UEFI and Microshaft and Intel for the mess they made.

I did that but it didn't help... but I'm 1 step further:
I deleted partition 1 (the efi partition) and then continue.
Then I get a warning about the EFI, I continued and it worked.

Now I get a problem with the GRUB:

The 'grub-efi-amd64' package failed to install into /target/. Without the Grub boot loard, the installed system will not boot

BTW:
Boot Mode UEFI Only is black in the BIOS (not editable)

EDIT: Boot Mode is fixed to Legacy

The legacy mode did the trick!

I did some brief latency testing... the i5 seems to perform way better than the i3, while on paper (online cpubenmark) only by a little bit.
