Will an AGP 8x card work in a 4x interface slot?
I'm hoping the 8x cards are backward compatible.

A few cards were released right when 8X hit the market, these cards operated at 0.8V only and would self-destruct when plugged into a 1.5V motherboard. Fortunately we haven't seen any of these in the last several years. |

Will an AGP 8x card work in a 4x interface slot?
Probably, but not guaranteed. I needed to replace the video card in
an old Tyan mobo computer with 4X socket. Two different Nvidia boards worked for a few minutes before quitting until restarted, and an ATI board would not even boot to Windows, though the BIOS messages were visible. I finally went on eBay and found a board which was only 2X-4X, and it has been working perfectly for nearly a year. -- Alan |

* billybob:
I'm hoping the 8x cards are backward compatible. No problem. All (yes, really *all*) AGP8x cards work in AGP4x slots. No exceptions. Benjamin |

This hardly has anything to do with AGP4x/8x compatibility but more with how much power the old mobo could deliver (were all the caps ok?), with a too weak PSU, problems with AGP and gfx drivers or any other of gazillion reasons.

Fortunately we haven't seen any of these in the last several years. Right, simply because it's not true ;-) Yes, it is. In reality, something what you described happened but when AGP_4x_ cards hit the market. The reason was that AGP4x lowered the signalling voltage to 1.5v. On AGP the signalling voltage (3.3v with AGP1x/2x, 1.5v with AGP4x and 1.5v/0.8v with AGP8x) is keyed into the AGP connector mechanically. There were a handful cards (all of the pre-Radeon/pre-Geforce Aera!) like several TNT2s, Rage128s and some charges of the Matrox G400 which came with AGP4x keying but which also only supported 3.3v signalling voltage. When the first boards with chipsets working with 1.5v signalling voltage only came out using these cards resulted in a fried AGP bridge if the mobo didn't had any protection circuit. This is basically a problem of the past because it's very unlikely anyone wants to use a card from that aera in a somewhat newer mobo. And none of the Radeons and none of the Geforce cards ever has been affected. However, this has nothing to do with the compatibility of AGP4x and AGP8x (which *always* is cross-compatible). All AGP8x GPUs do support 1.5v A few first-generation 8X cards did not support 1.5V. |
