I'm a bit behind the times when it comes to Ram speeds.. I have some PC2-8500 (1066MHz) doe's that mean the max speed my ram is guanteed for is 533MHz? so if i overclocked my FSB to 533MHz and kept a 1:1 ratio the ram would be running on spec?

That's correct, plenty of headroom on PC8500. I have my PC6400 running at 420fsb 1:1, meaning a slight overclock at 840mhz
 
DDR2-8500 is 1066MHz, 533MHz x 2, usually isnt cheap stuff and can clock a lot higher, its usually better to go for 800MHz or 667MHz memory and clock it to 1066MHz which can be achieved with decent memory
 
Would you guys say it's better then to ghave better MHZ on the ram as opposed to slower MHz and lower latency ?

EG:

DDR800 @ 700-750MHz @ 4-4-4-12
or
DDR800 @ 900MHz @ 5-5-5-18 (stock spd on my corsair xms2 @ 400mhz)

Click to expand...

i read a review a while ago where they tested using a data throughput test and found ram at higher speed with slacker timings to have a much higher data throughput than ram at a lower speed with low latency timings.

so i'd say that your Corsair at 900MHz @ 5-5-5-18 would be faster :)
 
At 900MHz it stays then! cheers :)

Still it's not at 1200mhz which is my fsb at the moment, but I will wait til DDR3 drops in price before going anywhere near that - at that time 1333fsb will be the norm though ;o
 
no the RAM is at 450MHz (900 DDR) and CPU fsb at 1200MHz - on my mobo there is no ratio option - it changes by itself you just select a RAM speed from a drop down list (which is a big list btw) and if your RAM can hack the speed then all is good.
