Bjr, ma boite vient de nous acheter 4 stations bi-Xeon 3.2Ghz dual core, jusque là super !
Sauf que sur les 4x1Go Go de Ram DDR2 (667), zindaube et les applis n'en reconnaisent que 2.5... zarb !
idem pour sandra qui n'en voit que 2...
J'ai cherché et vu sur d'autres forums que pas mal de monde avait ce pb.
Le revendeur n'y comprend rien, et l'assistance intel bah.......

donc ma config :

CM Intel S5000XVN
Procs : Intel Xeon 3.2Ghz dual core
Chipset : intel 5000X
Quadro FX1500 Nvidia
4x1Go SDram DDR2 667
zindowz$ XP pro sp2

Si quelqu'un a une idée...
J'ai été voir dans le bios (version recente du 8/8/2006)
il reconnait bien les 4Go
J'ai regardé le placement des barettes, il est conforme au precos.

HELP !!

J'ai trouvé çà :

Physical Address Extension

The Physical Address Extension (PAE) enables applications to address more than 4 GB of physical memory. It is supported by Intel processors. The following systems can use PAE to take advantage of physical memory beyond 4 GB:

* Windows Server 2003, Enterprise Edition
* Windows 2000 Datacenter Server
* Windows 2000 Advanced Server

To enable PAE, use the /PAE switch in the Boot.ini file. To disable PAE, use the /NOPAE switch.

With PAE enabled, the operating system moves from two-level linear address translation to three-level address translation. The extra layer of translation provides access to physical memory beyond 4 GB. Instead of a linear address being split into three separate fields for indexing into memory tables, it is split into four separate fields; a 2-bit field, two 9-bit fields, and a 12-bit field that corresponds to the page size implemented by Intel Architecture (4 KB).

Typically, a process can access up to 2 GB of memory address space (assuming the /3GB switch was not used), with some of the memory being physical memory and some being virtual memory. The memory manager uses PAE to provide more physical memory to an application, which reduces the need to swap memory to the page file and increases performance. The application itself is not aware of the actual memory size. All of the memory management and allocation of the PAE memory is handled by the memory manager independently of the application.

Applications that are 4GT-aware are likely to remain in physical memory rather than be paged out, which increases their performance. The exception is when the /3GB switch is used in conjunction with the /PAE switch. In this case, the operating system does not use any memory in excess of 16 GB. Therefore, if the system restarts with the /3GB entry in the Boot.ini file, and the system has more than 16 GB of physical memory, the additional physical random access memory (RAM) is not used by the operating system. Restarting the computer without the /3GB switch enables the use of all of the physical memory.

Address Windowing Extensions (AWE) enables applications to address more than 4 GB. AWE enables an application to reserve physical memory as nonpaged memory, then dynamically map portions of the nonpaged memory to its working set. This enables memory-intensive programs to reserve large amounts of physical memory for data without swapping to disk. Instead, the data is swapped between the working set and reserved memory above the 4 GB range. The memory above 4 GB is exposed to the memory manager and the AWE functions by PAE. Without PAE, AWE is unable to reserve memory in excess of 4 GB.

nous ce qu.on veux savoir c'est: est-ce que ca fonctionne

....Walou çà marche po
et enlever la ram virtuelle non plus....
Grrrrr...

Quelqu'un aurait une riche idée ??..
