Xpress 200m is not dedicated

Thread Starter 
There has been much confusion regarding this subject and I just want to clarify it once and for all. The 200m does not have 128mb dedicated and integrated. It is purely integrated.

Can be seen on:
www.newegg.com

I understand that the Xpress 200m uses system RAM. It is dedicated to the GPU but it is system RAM.(which means use at least 1 gig of ram)

The part that Im a little confused about is the 200m with Hypermemory. I got the feeling that if you have Hypermemory you have local memory. Here is what I read from ATI.

Quote:
Memory Interface
UMA mode operation requires no additional memory
HyperMemory™ is ATI’s innovative technology that seamlessly enables the Graphics Processing Unit to use a combination of local and shared system memory with real-time performance at a reduced consumer cost and up to 128MB of memory GDDR and DDR Support
Support for 2Mx32 (with 64-bit interface), 4Mx32, 8Mx32 and 16Mx16 memory devices
Asynchronous HyperTransport and memory controller interface speeds
Supports GDDR SDRAM self refresh mechanism
Supports dynamic CKE for power conservation (for GDDR SDRAM only)
What am I missing here?

Does that mean that the GPU will have lets say 128 megs of system ram allotted to it and through memory management it will be able to use more of the shared ram to help out when needed?

For instance lets say your laptop has 512 megs of RAM and you dont want to use up 128 megs of RAM on Video so you set it to 32 megs and the memory manager knows that if there is memory to spare then the GPU can use more then 32 as long as the OS doesnt need it.

If on the BIOS you set 32mb, it will NOT allow the OS to use more than 32mb for video memory.
Let's say you have 1024mb of system RAM, and you set 128mb for video memory on the BIOS. The Operating System (WinXP for example) will see that you have 896mb as RAM, and 128mb as video RAM. The video memory is "locked", that means WinXP will NOT be able to decrease the video memory (to 32mb for example) even if you don't use more than 32mb.
My suggestion is to use 64mb if you have 512mb of RAM, 128mb with 1024mb.

OK this is really very simple but many people dont really understand very quickly and then are like OOOHHHH... i see... lol.. anyways here goes...

The ATI Radeon Xpress 200M has 128MB of sharded video memory which makes it an IGP... This graphics card can be set to use up to 128MB of video memory in the BIOS it takes that amount of system memory you set it to and sections it off from the rest of the system so lets say you had 512MB of memory but you set your graphics card to use 32MB of memory. That 32MB of memory cannot be used by anything other than the graphics card. Which leaves you system with 480MB of memory that other programs can use...



This is what HP has to say about it...

The title of the thread is a little off becuase it is dedicated memory it's just dedicated from the normal RAM rather then having its own memory chips.

I understand all that but that still doesnt explain Hypermemory.

What Im saying is that if you have hypermemory it will have a certain amount of RAM that is only used for video and it has a certain amount that can be shared between the OS and video.

There are two different configurations for the Xpress 200M.
One has 128mb dedicated memory built onto mobo and can also share up to another 128mb with the system RAM(HP zv6000).
Then there is one without dedicated memory that can share up to 128mb with the system RAM(Compaq v2000z).

Heres what I am seeing for the Zv6000 series you can get 32 or 128 megs of seperate dedicated memory and with the 128 selection you can also use hypermemory which allows for sharing another 128 with the System OS.

The L2000 and others have the 200m but no built in RAM so it uses the System RAM but that RAM is locked so that the System can't use it only the Video can.


So basicly it depends on the system you get, some have built in Video RAM and some use system RAM.

Right and the zd6000 with the Shared/Dedicated with a total of 256MB seams to do nicely from what i have heard...

what about the r4000? i think it said 128mb with hyper memory. is that 128 dedicated and then another 128 can be added?

Yes,

The R4000 is the same as the Zv6000 it has the choice of the 32 meg and 128 meg dedicated RAM and the 128 option has hypermemory which allows you to share another 128 with the system..

why open different threads with the same question?

I have a R400 and I have played around a lot with it.

It is a dedicated card. Once and for all

It is a dedicated card.

it is a 256mb gpu with 128mb dedicated and 128mb from ram(better than integrated).

No more threads on this please.

The post wasnt started with a question it was started with a statement. You have now made the reverse statement and the fact is both of you are right and both of you are wrong.

The ATI XPRESS 200m has more then one setup, depending on the system you buy. Some have dedicated and some dont;

Some have 32megs of Vram and no Hypermemory;

Some have 128 megs of Vram and can use 128 megs of system ram as well;

Some have no dedicated ram and will use up to 128 megs of system ram;

And some have no dedicated ram and will use 128megs of system ram and also have productivity ports like a 6-1 card reader, a firewire port, and some usb ports.

correction the one that uses card reader firewire port etc has 128 dedicated and 128 from memory.

I dont think so Devarshi at least for the R2000z/L2000 series but please if your sure of that let me know it would be good news since that is the system I am getting.

whoooops!! you are in bad luck. This option is only available for R4000. It is mentioned on the shopping.hp.com website where all compaq models are listed. you will have to buy R4000 if you want 256mb of gpu(128dedicated plus 128 from ram).

I already expected that to be the case. It's not a big deal to me becuase for what I need a system for, the graphics are great. I have spent sometime working on one and they're not bad without the dedicated memory. They are still better then the intel IGP solutions that IBM and most pentiums use.
