I have become confused about the ATI X1600 on my laptop.
The brochure for the model said it had 128 memory.
I discovered subsequently about hypermemory and that it has 512 mb of it.
There is no indication in any information that it has any dedicated memory.
A program with Doom 3 said there was no video memory.
Do I have all shared memory or what?
Could it have been removed?
 
Hyper memory:
card system
128 256
256 512
512 1gb

So if you have less than 1gb of memory you can't get 512 for the card. That
is 128 meg on the card and balance is system memory.

I have a x1300 sitting here on my desk the above data is right off the box.

I often notice glitches with DVD playback. Largely a mystery,
but the sense is that sundry other things running interfere once in a while.
Any shared memory strikes me as potentially problematic.
This occurs with PowerDVD and WinDVD. I uninstalled WinDVD which
came with the laptop. It gives a 'burn in' effect and turning off hardware
acceleration gives a picture inferior to PowerDVD and Media Player Classic.
I do run PowerDVD with hardware acceleration (Avivo) but on rare
occasions it becomes stuttery. I tried with much of processes and services
switched off and it made no difference. I tried changing process priority
too.
I am still unclear of the patterns of this problem too, so no simple answer
seems to apply.

I only have the information on Catalyst to tell me anything and there is
no mention of dedicated memory whatsoever.
I have 1 gb RAM.

I notice too that the product info on the ati website makes no mention
of dedicated memory.

I only have the laptop's brochure and comments on the internet to go by.

I found too that someone else bought a new Dell desktop computer and had
problems with DVD playback with stuttering but I couldn't tell what was
causing it.

On Sapphire's site it mentions Hypermemory 2 (bottom of page), renders to
system memory and video memory. But you are right neither they or ATI
mention system memory. I ran my x1300 only for about a week and then didn't
watch any videos with it. My X1600XT does not have Hyper memory (256 DDR3)
I'm upgrading to a X1950XT, reviews look good and is much faster than my
1600 and is VIVO.

I would imagine that with shared memory there might be times that you would
get Stuttering in Video, as the memory might be busy doing other things and
free memory might be scarce.
