Increasing shared memory on the 8400M GS with HP DV2630ea

Hi All

I've bought the HP DV2630ea laptop and it has a 8400M GS chip on board with dedicated 64m graphics memory and currently uses no shared memory. The documentation says it can use up to 800M shared memory, but I cannot find how I can do this anywhere. Has anybody who has a HP notebook with the 8400M managed to increase their shared memory at all, and if so, how did they do it.

Any help would be appreciated

OS : Vista home premium
Laptop : T5250 1.50 GHz, 2048 MB DDR2 Ram, 160 GB 5400rpm SATA HDD
Video : NVIDIA® GeForce™ 8400M GS with 64m dedicated, 0M shared

Thanks,

 

There's really no point in doing this. You will not see any performance increases at all.

Also, the OS does this as it is needed. So the reason why it's not sharing anything is because you're not doing anything graphic intensive, thus saving your ram. But when you start a game, the OS will know that and begin to allocate more shared ram to the gpu (even tho that doesn't do anything for performance)

 

hi Adinu

Thanks for the reply. I have read around a bit and i am learning this myself now. I didn't know Vista did that, but do now. Still - the laptop runs new-ish titles like doom 3 well enough so I'm happy - just trying to tweak it

Thanks,

 

It's not just Vista, it's the others too. That's how turbocache works and is written in the drivers of the card, to let the OS allocate shared ram as it sees fit.
