512 mb video ram support - new 1G video card?

Forum Graphics & Displays : AMD Radeon 512 mb video ram support - new 1G video card?

PowerColor

Hello,
Asus A78n Deluxe with 512 AGP support. Will a new His 4670 Ice Q video card with 1g video ram work?

They are not compatible as the HD4670 is a PCI-Ex16 graphics card, whereas the Asus A78N-Deluxe only supports PCI or AGP graphics cards.

The HIS 4670 1G AGP 8x card not the PCI express

It is an AGP 8x card but the board says 512m is max supported as most likely 512 was the most common and 1gig cards were not yet released

It states that the product utilizes the PCI-Express x16-2.0 interface on there.

There are AGP versions of the HD 4670; like the HIS Ice Q.

Not sure what the OP means by "512 AGP support". Is that the aperture? I believe the way it works is if the video card is running low on memory, the system RAM will be used to store textures. Basically, the more VRAM the video card has the lower the aperture should be set to.

Back when I had an AGP Radeon X1900XT 512MB, I set the aperture to either 64MB or 128MB.

There is an AGP version as well. It should work fine, but that's an expensive card to put in a machine that old, I doubt you're going to see the performance increase you want.

In the motherboard BIOS the highest selection under Video card ram is 512. Bought the AGP HIS card and awaiting its arrival. Wondering if it will work and be supported by either of the 2 systems I have running both of which are Socket A with AGP. One ASUS A78n and an EPox 8rda3+. Maybe should have considered a system upgrade with good onbord video to start reasonbly affordable. Have decent peripherals in Socket A now and its looking expensive for a complete new system.

So the lower setting did not have a negative impact set to a lower number than the video cards higher onboard ram than apparently supported by the motherboard?

System RAM is slower than video RAM. You should have no problems.
