No, 4GB is nowhere near the max :)
e.g.: his OS, Vista Home Premium is capped at 16GB ram, not 4GB.
The max ram I have ever seen was on an exhibition:
- Redhat linux
- x86
- 256GB ram (32 identical 8GB memory sticks)
Currently available maximum to XP users:
- Windows XP SP2 64bit
- Memory Remapping
- 4GB ram
- Vista sucks, no amount of extra ram is worth the downgrade from XP to Vista.
NASA has:
- Linux on an SGI Altix supercomputer
- 1024 dual core CPUs (That's 2048 cores total)
- 4TB ram (4096 GB)
Dream configuration:
- Redhat Linux
- Custom built motherboard to support enough slots (They'll need 2 147 483 648 slots, if they use 8GB ram sticks.)
- 17 179 869 184 GB ram (16 exabytes or 16 777 216 TB)
