Studio XPS 1640 & Hypermemory

Thread Starter 
does anyone know how to disable the ati hypermemory? i recently got the 1640 with the 1gb radeon hd 4670 video card. i noticed i have 2813mb of video memory. with that in mind, i know it's being shared with the system memory. since i have 1gb of dedicated video memory, i'd rather not share with my system memory.

The shared memory only happens if the apps require it, which I doubt and personally have not seen on my 1/2 dedicated video gig.

How about just use the ATI driver and nothing else? (no extra utility that comes with it)

cheers ...

hmm...i'm using the drivers provided by dell. i haven't seen any option to disable the hypermemory. i just checked the ati website and their version of the driver appears to be different from dell. i guess i could try the ati driver.

Create a restore point first. Let us know how it turns out.

I am not really sure if you can disable hypermemory (ATI) or turbo cache (nVidia), but you can try limiting the amount the system uses physical ram for video purpose, either in your BIOS or system, and see if it does what you expect GPU behaviour to be?

My thinking is that the card would not "steal" memory from your physical ram unless it is needed.

ghn...you are correct. i got in touch with amd/ati reps and they said it can't be disabled. hypermemory will only use the system memory when it's needed and if it's available. unfortunately, my bios has no option to control the video card.

Keep an eye on system (apps) performance. I believe that software needs to be re-written to take advantage of these dings from ATI and NVidia.

I got my Studio XPS 1640 about a month after it was originally released (Going on 6 months now), so I have the ATI HD 3670 w/512MB. I'm sharing over 1750MB of memory w/ the system, and have not had any issues with it slowing down. As a matter of fact, I am running Windows 7 RTM 64-bit and it is running so much better than the Vista Ultimate 64-bit that I've dropped my system RAM usage from 30-40% (In Vista) down to 20-25%...

^^ Cool for a confirmation of non-negative-effect of hypermemory (turbo cache). Non-negative? Did I just say that?
