question about hypermemory

Ok I have been curious about hypermemory. I have a v2000z (Turion 1.6Ghz) and have looking around it seems that my x200m in it supports hypermemory right? so right now I have 128MB shared. I can't seem to find the setting in the latest ati drivers to enable upto 256MB. I have in the bios the video set to 128MB and in the ati drivers the UMA buffer to 128MB, does that mean I have hypermemory enabled already? OR does my laptop not suppost hypermemory?
Any help would be great.

 

Hi ELPEDRO,
If you have 128 meg of dedicated and 128 meg of UMA then you have the hypermemory enabled already. Youu might want to try teh system wthout the UMA enabled and see if it really makes any differense. I know that it didn't on my 5030. The 3D mark 05 scores were hardly any different.

Hope this helps.

The v2000z has no dedicated video memory, therefor you're essentially already using 128MB of "hypermemory". The v5000z and dv8000z have the 128MB dedicated memory option with their X200 GPUs.

 

Hmm, I would like to differ here. HyperMemory feature is little different from assigning RAM in the bios.

Assigning Memory in BIOS acts just like as if it is owned by/or dedicated to Video card( though it shared, but is completely allocated to Video, can not be used by System). Whether video cards needs that much memory at that time or not, does not matter. It simply takes that much memory out of total memory. It is Bios regulated/hardware feature.

Like ex: If you assign 128MB to Video in bios, Video card always holds to that memory irrespective of it needs or not( it may not even need 32MB at that time). It is as good as dedicated for that( I know it is slower, but in owning perspective).


Now, HyperMemory. It is part of software driver feature to assist the VideoCard based on Demand(Like Intel DVMT). It monitors the memory used by Video card, and if it sees need for more than what is allocated in bios, it grabs it from System memory upto the size allocated in bios(in addition to allocated by BIOS). It will be released once it is not needed and can be used by System.

Like Ex: You assigned 64MB in bios, and with HyperMemory feature, if the driver sees more demand, it can allocate upto another 64MB, making it total 128MB. And it releases that memory once it does not see anymore use.( if you assign 128MB in bios you could use upto 256MB with HyperMemory feature). BTW I do not think you can control that manually.

 

Hi Chinna,
The 5030 has a 128meg dedicated ram option installed. I have a designated 1024 meg of system ram when UMA is disabled in the bios, and 872 meg when the 128 meg option with uma enabled is selected. The ATI Xpress 200m in this machine does have 128 meg of dedicated video memory. This is not a part of the system RAM, while you can further allocate up to an additional 128 meg of system ram through the use of the SidePort and UMA option.
The shared memory option does not even appear in the BIOS menu until the UMA and Sideport option has been selected.

 

To my knowledge HyperMemory has 256MB limitation. So if you assign 256MB(128MB dedicated+128MB UMA), then it won't grab anymore memory from main system memory.( So, HyperMemory feature would not work anymore as 256MB limit is reached).

 

HI chinna n,
Yes we agree on this. The dedicated memory is not system ram and the uma is user allocatable up to an additional 128 meg through the bios (atleast on the 5030).
