I just bought and installed this 8600GTS and the the NVIDIA Control Panel is reading the memory bus at 1222Mhz, whereas NewEgg say it is 2100Mhz, am I missing something?

Newegg says 2100MHz effective.

You are not seeing the effective speed.

Would you mind elaborating a bit? I'm not sure I understand.

Since the memory uses DDR RAM, or Double Data Rate, there are two directions the data goes, up and down (to keep it simple).

Effective means when you add the speeds together. The correct way is the single rate, not the combines ones.

Here's a link to help you understand better.

Ah well that makes sense as it was originally showing 1050 memory bus. Is it like that for all cards then? As I notice there are some 8600GTS' on NewEgg that don't say "Effective" by them.

All card are like that, and pretty much sites show the effective speed. Just consider them effective unless they look funny, or otherwise stated.

Checking the speed through a program usually shows the non-effective speed.
