Does 1st-gen Intel Core support GPU folding?

I have a spare GPU sitting around (an RTX 2070 Super), but unfortunately I can't fit a 2nd GPU in my main rig. I have an old 1st-gen Core i3-530 and a Dell motherboard sitting around that I could put the GPU into, and was wondering if a CPU that old (no AVX, etc.) can still support GPU folding. Thanks!

Never hurts to try. Install 64bit OS, and see what happens.
I am not aware of fahclient's requirement for CPU to have AVX. Just 64bit. As long as you do not try to fold on that CPU, you should be fine

Yes, first generation iX is the minimum requirement for GPU folding. I'm running an i7 920 and an i7 860 without issues.
Older CPUs (Core 2 Duo / Quad) won't be able to run GPU cores. They lacks SSE 4.2 support that is required.

I believe the current cpu cores are for
sse4.1, avx-256, or avx2-256

No. ARM NEON is 128, I believe.

I thought x86 AVX was 128, AVX2 bumped it to 256

Iām looking at the buildbot settings. It is what I said, albeit the cores were previously built by someone else. Probably with github actions. So they could be different.
