Usually if a motherboard isnt AGP 8x, an AGP 8x video card will scale to 4x. Hence the 4x/8x. :)

Now you tell me! :laugh: He's already ordered the card! :roll:

Still good to know.

From what I remember the i850e supports AGP 4x. The HD 2400 you ordered should run on it.

ok ty i heard every agp slot is interchangeable meaning it runs 8x but downclocks them?

I'm a little rusty on the 8x/4x AGP slot and I was going off of the newer PCI-E 8x/16x controlled by the chipset of the motherboard. So thats why I asked LemonadeSoda to help cause this guy knows AGP inside and out.

Signalling voltage of AGP interface
Original AGP (1x) used 3.3v
AGP 4x used 1.5v
AGP 8x used 0.8v

DONT MIX AND MATCH incompatible slots and cards or you can RUIN the card and/or RUIN the mainboard. Some cards are however 4x/8x slot compatible, meaning you can put them in either. Some however are not multi-slot capable.

Signaling voltage of PCIe interface
D+ =+0.4v to 0.5v
D- =-0.4v to -0.5v
=0.8 to 1.0v differential

Rialto based AGP cards (essentially a PCIe interfaced GPU core with a Rialto converter to AGP) works at 0.8v. It is therefore AGP 8x only.

I think you would damage an non-4x compatible AGP 8x card in an AGP 4x slot.
