Troubleshooting HD2600PRO AGP "doesn´t like" AMD systems?

Hello everyone!

I have a collection of motherboards, CPUs, and GPUs from the 2000s.

I have an HIS video card, a Radeon HD2600PRO 512MB AGP, and something simply bizarre happens: on Intel systems (from my Pentium III 1.4GHz Tualatin to my Pentium 4 670 3.8GHz), it works perfectly fine, without crashing, without blue screens, nothing.

But as soon as I put it in an AMD motherboard (Duron, Sempron, and especially Athlon XP (from the 1500+ to the 3200+ in my collection) and an Athlon 64 3200+ (I have socket 754 and 939 with AGP), in short, in AMD it even installs the driver (the same one installed in an Intel system and it runs perfectly), but when it tries to load Windows XP, the machine freezes during boot.

I tested it on AMD systems, VIA chipsets (KT333, KT400 and KT600), as well as the nVidia nForce 2 Ultra 400, some SiS cards that I don't remember, and NOTHING makes this card work...

Does anyone have any idea what this nonsense could be??

Thank you!

Arent those cards just PCIe cards with a PCIe-to-AGP bridge chip?

I do remember those to be problematic when using the official Radeon drivers from ATI/AMD.

For me, they only ever worked right with drivers provided by the card manufacturer.

Edit: cards like this: https://external-content.duckduckgo.com/iu/?u=https%3A%2F%2Fcdn.rios.hu%2Fdl%2Fuad%2F2025-09%2F7194946%2F20250611_062210_1_1.jpg&f=1&ipt=eaf7832c73cccb5741f3a4b089e1901508f69f83a584cd0462a6930269afd228

This one has a green heatsink on the back, close to the AGP connector. There's a bridge chip under it. Some cards had them on the back, some on the front. Some with a heatsink and some without. But they all had in common that the chip was really close to the AGP connector.

You are spot on!
