AGR slot & 3.3V 3Dfx cards..
09.03.09 at 11:08:57

..pretty sure we already had a topic about this somewhere,but I'm either doing something horribly wrong or the search is not working as it should.

anyway,I can finally confirm that all 3.3V 3dfx cards (up to v5 5500agp) work fine in the AGR slot,all you have to do is remove the agp8x key from the slot and you are ready to go..

original post: http://forum.3dfx.cz/viewtopic.php?p=39030#39030

note: the bugged pic in the original topic is displaying the infamous FSAA bug (should be fixed in latest builds of SFFT driver),and it is not related to the hardware.

Reply #3 - 09.03.09 at 16:18:12 voodoo5 5500agp is notoriously unstable,unless there is enough juice in the slot.I don't think there is any way to check,but as long as everything is stable,I would say that full 3.3V are supplied. if the slot does not have enough power,you have to do all sort of nasty stuff to get it there..

Reply #9 - 21.11.10 at 08:42:12 The cards are working at 3,3Volt ? did u manage to measure the AGR voltage ? Would a v5 6000 run in AGR slot ? The Thread on the CZ forum is not updated anymore.

Maybe at lower resolutions, max framerate at higher resolutions has already been found need more video memory to improve these.

AGP 8X:
AGP 2.0 ---1.5V
AGP 3.0 ---0.8V
Plug 3.3V Card in mobo of AGP 2.0 means 3.3V card working in 1.5V and it's 0.8V to a AGP 3.0 mobo,right?
So,how do SDRAMs RUN under such low voltage?Equivalent to De-over colck of RAMs greatly,is it still work?Theoretically the card will not crash,but it's an abnormal condition i think.

@Pps47: can u please post some pictures with the system, construction and so on ? ( picture from AGR w/out the card pluged ).

Is the voodoo5 working from a long time ( years ? ) in this slot ? I'm interested if there are problems by running it long time.
If there is some incompatibilty, the card normaly failed or die after a couple of months.
