View Full Version : AGP to PCI

01-05-2002, 06:08 PM
I have an old Stealth II G460 video card that I just took out of my computer to put in a GeForce 2 video card. I planned on puttin ght Stealth II into my older computer in my room, but the Stealth II requires an AGP slot, and my older computer only has PCI slots.

Is there such thing as an AGP to PCI converter that I could get somewhere? Or is that yet to be invented...

No, the entire archiecture and bus it operates on is completely different, it cannot be conveted.

speaking of adaptors... i was just thinking about memory expansion riser boards, y'know... and do those just work by splitting the throughput of the data path to seperate slots? i'd figure so since that seems the most logical. is that correct? and i suppose you couldn't stack them right? i've never used one, but i am very curious. also, physically there couldn't be a AGP/PCI converter [unless you had a softer, compact ide-cable-ish type translation cable, but that's just physically getting it connected]...

what about new graphics cards that are still using PCI? Are there any that still use PCI or have they all gone over to using AGP?

You can get a ATI Radeon PCI 32MB. I think you can even get the All-in-Wonder edition. I only know this because I have a ****ty HP-POS which I got septermber 2000 and it doesnt even have a AGP. I was going to replace the motherboard but its propitory(sp??). Next computer I get Im putting together. I got screwed on a compaq I got too.

perhaps it'd just be less expensive to just get a new motherboard... besides, that type of hardware translation would probably also be proprietory, if at all existant.

You mean the old expanded memory cards? That actually used a memory manager that swapped out 16k chunks to/from the board to/from conventional memory. Kinda like swap files on your hard drive, only this was (at the time at least) faster.

Compaq and HP are two of the worst joints around. If you gotta go with a big company, Gateway isn't too terrible. They make clean systems you can get around in and parts that you can actually work with.

As has been said they both use and access the bus in very different ways. There would be no way to make an adaptor to compensate for those differences. Also, if there was an adaptor and your board was all PCI, then it could never support AGP. It requires totally different circuitry. If your board was AGP with PCI slots, there would be no reason for an adaptor since you would just put your PCI video card in the first PCI slot. AGP boards can use PCI cards (video being one of them), but PCI only boards cannot support AGP.

It would be impossible to convert an AGP to a PCI. For one thing, an adapter for it would never fit, second, they have different ways of doing things, therefore it would probably crash your computer.

There are less and less graphics cards that run on PCI, mostly because AGP is so much faster. You can probably get older cards on the internet, like a GeForce 2 MMX 400 on PCI, but if you want the latest, I'd suggest an AGP.
