need help shoving a CPU in a pc it's very much not intended to go into (feddit.it)

Around six months ago (and luckily before the whole ram shortage) I managed to scrounge up enough money to build this monstrosity of a machine, based on what I thought was a lenovo thinkcentre m700... More on that further down.

The whole mod works wonderfully. But the problem i'm facing is that the poor i5-6500 it came with just cannot keep up with what i'm doing with it and bottlenecks the whole machine.

Without any mods. The Best CPU i can put into it is an i7-6700. Which is still a 6th gen CPU... But it's still about 70€ where I live. While for some reason I can find a lot of i3-9100. For 20-30€. Which from what I understand are B0 stepping chips and don't require pin modding to be used. And should still be a good upgrade.

The last problem was the BIOS. The bios on this machine is not meant to support such a new chip. But I remember reading people having success with a program called "coffeetime" to shoehorn the microcode to use newer cpus.

When I went to sanity check what the machine's bios said. I found out it's a actually an m800. Not an m700. This raises a problem. Since it's chipset is a q150. That has the problem of having a stricter/ more in depth Intel ME. That from what I managed to find requires somekind of bypass.

Do you think this is still feasible to do? And do you know if there is any safe source for coffeetime / some guide to do this mod by hand? Since having a random software that I can't read the source of modify the bios of my machine feels a bit iffy.

Aw thank you :-) But to be honest. I ain't that good at this. All I know is mostly from reading wikis and following work already done by others.

The real beasts are the ones that actually discover that this is possibile. Eg. The console modding community. (I'm still impressed at how dumb of a way they managed to mod the switch: it literally shorts the CPU to make it skip checks) or the guys at win-raid forums. Where I think the whole research about this upgrade being possibile started in the first place.

English isn't my first language. So I'm not sure if I managed to get my point across. But essentially I'm saying: in the sea there is always a bigger fish. And in this world you never finish learning. There will always be someone that knows more than us.

Also if you do have a lot of these machines... They really aren't bad ones. Win 10 ltsc runs like a dream on these. And linux is right at home on them. It's only really a bottleneck for me because I literally use my machine for fluid simulation for my studies. But even for games. An half height gpu like the RX 6400 gives you a decently stout pc. If you aren't aiming for full res upscaled AAA games. Hell. The steam deck has shown just how much we can do with more modest specs.
