Placa de vídeo notebook intelbras i35

Não tem nada no BIOS do i35 que permita aumentar a quantidade de RAM destinada ao compartilhamento pro video.

Por isso o compartilhamento é feito de forma automática pelo próprio sistema (no caso da X3100 vai até 384Mb); pesquise por alocação dinâmica de memória; tem alguns tópicos falando sobre isso.

Dynamic Video Memory - Intel Graphics utilize a shared memory architecture (often referred to as a unified memory architecture or UMA) – system memory is used for both graphics and system purposes. Instead of using dedicated local memory, as is the case on the majority of discrete graphics cards today, a portion of the system memory is allocated to be used as video memory. Additionally, a small amount of system memory is permanently allocated to video memory by the BIOS. This amount is usually one or eight megabytes (most OEMs set eight megabytes). Systems shipping with a Windows Vista* logo are required to set eight megabytes of pre-allocated memory.

Dynamic Video Management Technology (DVMT) allows additional system memory to be dynamically allocated for graphics usages based o n application need. Once the application is closed, the memory that was allocated is released and is then available for system use. The purpose of dynamically allocating memory for graphics use is to ensure a solid balance between system performance and graphics performance. For example, if a user is simply editing text, there would be no need for the graphics to take up a large amount of the system’s memory. In such a case, it would be best if more memory was allocated to the system. On the other hand, if the user was to start up a 3D game, there would be a need for more of the shared memory to be used as graphics memory.

Windows Vista* - On systems running Windows Vista* the graphics driver will ignore the system BIOS settings for memory allocation due to differing operating system requirements from Windows XP. Instead the graphics driver will allocate a combination of fixed and dynamic memory based on the amount of system memory detected. This enables BIOS vendors to create a unified system BIOS for Windows XP* and Vista systems. A certain amount of fixed memory is required so that the driver can ensure a mode change from the current mode to any supported mode. For systems with 512 megabytes of system memory (minimum requirement for Windows Vista*) the driver will allocate 32 megabytes of fixed video memory (8MB from pre-allocated) and up to 32 megabytes of dynamic video memory for a total of 64 megabytes of video memory. If the system has more than 768 megabytes of memory then the graphics driver will allocate 64 megabytes of fixed video memory and the rest will be allocated dynamically depending on how much system memory there is. The chart below shows the specific memory allocation.

Resumindo: uma pequena quantidade da memória RAM é permanentemente alocada para o chip de video (geralmente algo entre 1Mb - 8MB, que são os oito megas que você tá vendo ai); essa quantidade de memoria vai aumentar de acordo com a necessidade gráfica do momento: se estiver rodando um game, a X3100 vai pegar emprestado mais memória da RAM instalada; quando parar de rodar o game, ela vai devolver os megas que pegou emprestado.

No Windows Vista vai ser um poquinho diferente: de acordo com quantidade de memória RAM que estiver instalada no notebook, a X3100 fixa X megas emprestados e também vai poder pegar emprestado mais Y megas de acordo com a necessidade; dá uma olhada nessa tabela ai :
