Do I have Turbocache?

[kent]

I bought the $30AR eVGA 7300GS with 128MB DDR2 RAM.

I was doing a 3DMark06 loop (don't laugh) to stability test and 3DMark says I have 1008MB of RAM (Two 512MB sticks of Mushkin DDR400)

Does that mean I have turbocache? Is there a way to disable it?

Yes, I believe the 7300GS uses TurboCache. I don't think you can disable it, but I also don't see why you'd want to.

Its in the control panel if you wanna disabled it, heres a pic

You have turbocache. No, you don't want to disable it.

Your video card has a 64-bit local memory bus with fairly slow memory, which is pathetic. To make up for this pathetic memory bandwidth, the card uses your main memory for textures. This means it only has to use local bandwidth for the framebuffer, which means better performance.

It's not so bad, really - your performance will be worse if you turn it off, because now the video card is using onboard bandwidth for both textures and the framebuffer. In any case, its better than an onboard solution because it uses ZERO memory unless you're playing a 3D game.

The only way to improve performance with a turbocache card is to sell it and get something better...or overclock your system ram
