NVIDIA Turbocache

I have a Toshiba Satellite A100 series notebook with a dedicated 256MB nVIDIA GeForce Go 7600....I know that it is not a very powerful GPU compared to the 7900...but it runs cooler....and meets my medium gaming needs...

Does it support Turbocache? What is Turbocache and how do I know whether my GPU supports Turbocache?

 

Yes it does, but it's all automatic and will actually do very little for you so dont worry about it. If you really care what it does, then google is your friend, or even this boards search function.

 

Yeah i have heard it does though i have not seen it work on my go7600. turbocache basically takes memory from your system RAM and adds it to the dedicated RAM that your graphics card already has. its really designed for those cards that need alot of video RAM but your go7600 has 256MB and it is just not capable of utilising anymore RAM even if it had 512MB dedicated. so the 256MB go7600 doesnt need turbocache even if it supports it and the 5112MB version out there is just a marketing ploy to entice people into buying a product which can never use 512MB of RAM anyways.

 

Turbocache is the technology that allows a part of computer memmory to be used as a video memory. So the video card becomes cheaper, because less mem is used in it, and cpu will have less availiable memory too.
I think it is used in Go 7300 and 6200 GPU. Correct me if I'm wrong...
So it would be better if your gpu has its own memory, than Turbocache support...

 

The whole point is, even cards that dont state using it, use it to fill any extra they need, ie a 256mb card needing 260mb of ram would use 4mb of turbo cache whether it is on the box or not. Your card is unlikely to need it. its a fancy name for crapping out basically, and its not much faster than the AGP appature system.

 

Yes. Dedicated memory is always better than shared.

 

The Go 7600 supports Turbocache. It's either 256 MB or 512 MB dedicated VRAM, but you don't need the 512 MB version - the Go 7600 doesn't need that much memory because it can only use the 256 MB effectively.

The Go 7200, 7300, and 7400 all have shared memory. Go 7600 and upwards, it's all dedicated VRAM.

 

The GeForce Go7600 does not support TurboCache. TurboCache, unlike ATI's HyperMemory, is a hardware feature and not a software feature. TurboCache support is not built into the Go7600 and therefore it cannot use it. The Go7600 can use shared memory but it's not via TurboCache.

 

That's what I meant. Complete and terrible typo by me, you can see in the second half of my post that that's what I meant to say

 

I know you knew that the Go7600 didn't use TC, I was mainly rebutting the other posts.

 

So I assume from this that system ram can be allocated to the 7600 the old-fashioned way, via the bios? (Not that it would help anything)
