Il est dit:
Max memory size refers to the maximum memory capacity supported by the processor 4Go
Mais mon processeur est 64bits donc limité à je sais plus combien de RAM (128 Go je crois)
A force de lire ce pdf je commence à de nouveau avoir des doute car ici:
The “Top of Memory” (TOM) register reflects the total amount of populated physical memory. This is NOT necessarily the highest main memory address (holes may exist in main memory address map due to addresses allocated for memory mapped IO above TOM). The Top of Upper Usable Dram (TOUUD) register reflects the total amount of addressable DRAM. If reclaim is disabled, TOUUD will reflect TOM. If reclaim is enabled, then it will reflect the reclaim limit. Also, the reclaim base will be the same as TOM to the nearest 64 MB alignment plus 1 MB. TOLUD register is restricted to 4 GB memory (A[31:20]); however, the (G)MCH can support up to 16 GB, limited by DRAM pins. For physical memory greater than 4 GB, the TOUUD register helps identify the address range in between the 4 GB boundary and the top of physical memory. This identifies memory that can be directly accessed (including reclaim address calculation) which is useful for memory access indication, early path indication, and trusted read indication. When reclaim is enabled, TOLUD must be 64 MB plus 1 MB aligned, but when reclaim is disabled, TOLUD can be 1 MB aligned. C1DRB3 cannot be used directly to determine the effective size of memory as the values programmed in the DRBs depend on the memory mode (Flex memory mode, interleaved). The Reclaim Base/Limit registers also can not be used because reclaim can be disabled. The C0DRB3 register is used for memory channel identification (channel 0 vs. channel 1) in the case of Flex memory mode operation
du coup il peut prendre jusqu’à 16Go de RAM
