Any way to dedicate more Ram to Gfx card?

SSJX · 11th June 2007, 8:30 PM

I have a 9400 running with a t7400 c2d (2ghz), 2gb 667mhz ram, and a 256mb 7900gs go gfx card. When I'm gaming, I'm assuming no where near 2gb is being used, so I'm wondering is there any way I could dedicate some of the physical ram to the 7900, similar to the Turbocache model of the Geforce Go 7400?

and would I notice any advantages, eg. an increase in fps?

bump because i'm still wondering

I highly doubt you'd be able to allocate more RAM to the video card, either way, it wouldn't increase performance as the GPU can access it's own RAM much quicker than it can with the system RAM.

I think that's how it goes.

I noticed today the XPSM1330 at work had 800MB Video memory so maybe it can be done

It takes as much as it needs.

Unless your card supports turbocache i dont think it can be done.

That's correct. Sharing system RAM works reasonably well for slow cards, where the 4GB of bandwidth available through PCIe is almost as high as the bandwidth to the onboard RAM (or higher). It doesn't work well for a 7900GS with 32GB/s bandwidth to its onboard RAM.

Quite apart from that, the 7900GS comes with 256MB of RAM. That's enough for the card; it's very unlikely to be able to use more than that while maintaining useful framerates.

I dont know how or if it should but this is what mine says.

Apparently it is only suppose to be 256 on board + 256 hypermemory.... Dunno why it has so much
