    Well, after having sorted out all the crap with my motherboard and HD's. I've been experiencing a bit of instability. I decided to run a few tests with memtest86 to determine the limits of my memory in order to narrow down the causes.

    My memory is 2 sticks of 256Mb Corsair XMS3500.

    I decided to find out what the fastest speed i could run it at 5-2-2-2 and get no errors on memtest86 (including test 5.) To my horror, any speed above 190 MHz resulted in errors on test 5! I thought that this ram could do better than this, and the mobo is rated to 200, so it cant be that. (by the way, the chipset was at 1.8v and the ram at 2.9v).

    Then, i decided to see what the highest speed i could reach at 9-5-5-2.5 timings (slow, i know :D) and wven more shockingly, it was the same! even at 192 (for some reason the memory speed skips to 192 when the FSB is at 191). wtf is going on?! Discounting test 5, the memory was fine at 210 5-2-2-2. anyone got any insight they can share?

    el sp00nio :sigh:

    Depends on how many erros you get, one or two is fine and you shouldnt worry about it.

    Maybe the board doesn't like to run at that speed, try at 200mhz as the pci and agp port will be in spec as your motherboard can run at 200mhz.

    No errors are acceptable.
