AGP its too picky and Bsods with the majority of the Vcards (tnt2, geforce 2 and 4)

They are probably running at AGP 2x, which is a no-no for most SS7 boards. You can confirm this with Everest/Aida32/Aida64.
You need to force AGP 1x - there are various ways of doing that: either by using some earlier VIA 4in1 drivers and installing the AGP driver in “normal” mode (NOT turbo mode), or by applying some registry tweaks available for nvidia drivers.

Please note that disabling AGP 2x in the BIOS settings might not always work, depending on the motherboard/BIOS version, so it’s better to always confirm the AGP speed with the aforementioned third party software.

Did anyone ever figure out why SS7 hates AGP 2x ? was it an electrical issue or just shitty chipset and drivers ?

I’m thinking bios or mobo design.

I finally found a mobo that works with full agp settings freeway ti5vgf. Having to use single sided memory sucks though

I think it's a combination of both. I mean, VIA and ALI reverse-engineered Intel's AGP design (in order to avoid paying Intel what would've been an INSANE amount of money at the time), and the end result was obviously suboptimal.
Having said that, certain SS7 motherboards handle AGP 2X better than others, so there's definitely more to it than just simply chipset and drivers.
Furthermore, I've even seen (cheap) 440BX motherboards that were fussy at AGP 2X, so it's not exclusive to SS7/non-Intel chipsets.

Starting with VIA KT133A / KT266A, these issues were mostly fixed (even AGP 4X is perfectly stable on these) - partly because VIA had greatly improved its chipsets by that point, but also because VIA boards were not just "cheap alternatives" anymore, so manufacturers were actually using good designs and (usually) good components.
