4GB of RAM
A 32-bit processor has ans(a) (a) 32 registers (b) 32 I/O devices (c) 32 Mb of RAM
upto 4 gb of ram on a 32 bit operating system xp
Theoretically, a 64-bit processor can address up to 16 EB (17.2 billion GB) of RAM. Realistically, the amount is far more limited, due to current memory technologies, space considerations, and limited chipsets. Depending on the other hardware, a 64-bit processor can access between 4 GB and 128 GB.
Yes, however it depends on your operating system and if its a 64 or 32 bit processor
The difference between 2.66 dual core processor, and 64-bit dual core processor, is really two different processor specifications. 2.66 is actually 2.66Ghz, which is the clock speed of the processor. The clock speed tells you how many times the processor can execute instructions per second. A dual core processor is a processor with two cores on one die. This can be thought of as having two processors in one. The bit specification of a processor tells you how many binary instructions a processor can execute per clock cycle. Most processors today are 32-bit (32 binary instructions per clock cycle) or 64-bit (64 binary instructions per clock cycle). More RAM can be used with a 64-bit processor. A 32-bit processor is limited to addressing 4 Gigabytes of RAM, while a 64-bit process can address (theoretically) 16 Exabytes of RAM.

The processor size or speed does not determine how much RAM your system needs. Generally speaking, the newer the system, the more RAM you can add. The amount of RAM slots on a motherboard and the motherboard's own subsystem (the BIOS) will determine how much RAM you can add to a particular motherboard.
An Intel atom processor will support at around 2 gb of ram
Any 64-bit processor with a 64-bit chipset should be able to. For instance, a Core 2 Duo on a 975X. Some older 32-bit server processors and motherboards could also address 6 GB with PAE enabled, but these were much more limited in what you could actually accomplish with them.
Simply speaking, the RAM holds the numbers whereas the Processor crunches them.
