2 x 4GB Memory (Tested good on 8 passes each)ĪMD HD 5570 Graphics Card. Medion Erazer : PC MT 15 Type: MED MT 672. I have tried everything to get my Old Bucket to run on 8GB… It should do…I have emailed MSI …you name it I’ve tried it…
It is only possible to make full use of the 4GB by activating an additional extension (PAE – Physical Address Extension) and using a 32-Bit server variant.īut there are exceptions to this process, Windows Server 2003 Web-Edition, for example, is hard locked to a maximum of 2GB of memory.Ģ thoughts on “ Memory Remapping at 64-bit – what is that?” This is due to a restriction put in place by Microsoft. Windows Vista behaves the same way: after initialising Memory Remapping, the system will display 4GB of usable memory but only uses 3,25GB. Windows XP, for example, will continue to use 3,25GB, even after Memory Remapping. Memory Remapping isn’t much use to 32-Bit systems however, as the system limitation of 32-Bits ultimately corresponds to 4GB. It renders the previously “invisible” memory, beyond the 4GB limitation, visible. Memory Remapping allows for the installed but previously unusable memory to be utilised to its full potential. Unlocking the full potential of your memory with Memory Remapping Today, computer users will exceed those numbers by a margin that 32-Bit systems were not designed to handle. For example, 512MB were considered sufficient at that point in time. Up until a few years ago, the address range was larger than the amount of memory being used. The lion’s share of the memory that the BIOS reserves is taken by the graphics card. The amount of memory reserved is usually somewhere between 3 and 4GB, but never exceeds the 32-Bit limitation. memory) for these input & output devices. The BIOS on a motherboard reserves a not insignificant amount of addresses (i.e. This means that only 32-bit addresses can be recognised by these components. Not only PCI and AGP-cards, but also the IDE-bus are only capable of operating at a 32-bit level.
Whoever attempts to install more than 3GB into their system will notice that despite correctly installing the devices, both the system and the BIOS will report that only a capacity of 3.25GB is available.
Memory Remapping is also known as the “4GB problem” and frustrates many PC users. What exactly does “Memory Remapping“ mean?
