OK, so on upgrading to 2GB of RAM I checked what CPU-z had to say and it came up with this:
Now I always thought that CPUz just showed the speeds that the RAM is capable of, and that that is usually options below the rated speed (i.e. less than PC6400 speed). Is this 500Mhz option just a false reading or do you think that my modules are capable of that?
I know that the quickest answer is to test them, but I wanted a general consensus before I risk nuking my modules with too high an overclock.
