Greetings,
I'm looking for a possible list of old AMD Socket A boards (I've got three Athlon XP chips laying around already) that have AGP x1 or x2 speed that are 3.3 volt compliant. I'm looking at building a new machine that I can use my old Voodoo cards in without frying them with a x4 or x8 board. Posting the question here as my searches have not really gotten very good results and it may just be that there's not many available or I'm using the wrong search criteria but using duckduckgo or google hasn't brought up a lot of options. Figured I'd see if there was a list here that someone may have created already or any suggestions on what to look for.

Thanks,

Hi,

Look at it from a chipset point of view. This site is a good resource.

KT333 is the fastest that still supports 3.3V.
KT333CF is a downclocked KT400 and therefore only supports 1.5V.

Best CPU for these is the Athlon XP 3200+ (AXDA3200DKV4D), but those are very rare.
Athlon XP 3000+ (AXDA3000DKV4D) can be found easily.
If you find one that was produced before Week 39 of 2003, they even have an open multiplier.

No problem.
You might find this thread useful:

I've seen the ECS and Biostar for very cheap.
When I found this beauty for 20€ shipped, I didn't think twice:

Came with crap CPU + crap RAM, which I did upgrade. Around 50 bucks total. Still saving cash for the Voodoo5 5500.
Oh and by the way: It doesn't run with 3 RAM sticks. Seems to be a common problem with KT333 boards.

Don't like the desktop Athlon XPs... The mobile version XP-M are way better, just get one of these instead..
