what does the speed of ram mean/depend on, for example i want to buy 512 ram, i have a 2.2 GHz processor, and already have 512 ram, what speed of ram do it get? does it depend on my processor or motherboard or just higher speed ram is better. I mostly know about software and very little about hardware. Help please.
Trust me, get the faster PC3200 ram, I think it’s about £2 more or something silly like that, and you can sell it of for a higher price when you upgrade.
You need PC2700 RAM.

ok the fsb speed is 166.5 mhz
the bus speed is 333.1 mhz

Might well be a AMD 3200+, they run at a stock 2.2ghz. If that’s the case you need PC3200/200mhz DDR ram. If you are into over clocking you could spend a little more and get faster ram, this will give you more head space for the processor as the memory won't be restricting it.
The processor speed and the memory speed are two different things. You might have a 2.2 GHz processor with 100 MHz memory, or 133 MHz memory, or 166 MHz memory or even 200 MHz memory. Now the processor speed would all be the same, but with faster memory the processor can get data to it faster, thus making the entire system faster all round. Higher is better.
There is another type of speed associated with memory, the latency. That figure is given as CAS 2 or 2.5 or 3 normally. That refers to how long it takes the memory to react to a command basically. Lower is better for latencies.
Knowing that you have a 2.2 GHz processor doesn't really help me tell you what speed of RAM you need. It could be an Intel processor, or an AMD processor.

Tell me the FSB speed and bus speed, you'll find them in the bottom left corner, then I can tell you what RAM you need.

how do you find out that?

it depends on what type of RAM your motherboard supports, and the bus speed of the CPU/existing RAM.
