So I have an Asus CUSL2-C board and a 1133 Mhz Tualatin-S Pentium 3. Is it possible to make it work in this board? How do I need to modify it? The board can output voltages as low as 1,5V (I tested it with a 566 Mhz Celeron).

Your board has an FC-PGA pinout, the Tualatin uses FC-PGA2. You can either mod the CPU pins, mod the board or use an interposer.

Here's a guide for the CUBX (exactly same socket as CUSL2-C): http://www.geocities.ws/tuacubx/reads/MSMG.htm

I have this motherboard working with a 1.4ghz Tualatin-S Pentium 3

Did you need to use a modified BIOS? What pin modding did you do? Is running my 1,13 Ghz 1,45V Tualatin at 1,5V not going to harm it? Will my cooler be sufficient?

He is pulling your leg - the board in that photo is a DFI CA64-TC which supports Tualatin cpu's out of the box.

Yeah, but I later purchased another Asus CUS2-C motherboard and it working again.
I can confirm because the Asus CUS2-C is listed in bootup screen with Tualatin 1.4ghz CPU.
I am using 256mb SDRAM PC-1333
Sometimes is clocks down to 933mhz.
Not sure why, I think the battery is low.
But I use the bios soft cpu menu and I also set the jumpers for 1.4ghz.

What cooler are you using? How much +5V from the PSU? Did you need to modify the BIOS or flash the TUSL2-C BIOS?

By the way, it's "CUSL2" and not "CUS2".

Yes, I think I updated the bios to newest version.
I am using a CPU cooler called tornado or something like that and I am using a fan speed controller
And I have the fan speed set to about medium.
I am using the Bios Soft CPU menu default settings.

CPU settings = 133 x 10.5 = 1.4ghz

Originally, I put this computer together back in 2018
It been thru a few upgrades and I exactly remember what I did.
But it is working today with the Asus CUSL2 motherboard.

I will post photos of bios setup later
