Ram is 400 mhz Bios Speed is 333 Mhz?


ive been having problems with pc freezing which requires hard reboot whilst playing a cpu hungry game (left 4 dead 2).
this has happened quite a lot and its very frustrating. i have replaced power supply (now have 550w), cleaned parts and re-applied thermal paste (cpu temp now around 59c in game) and checked ram sticks are in place correctly.
the freezing continues. now i should make sure my bios settings are correct for the ram but this has got me confused!

please could somebody in the know take a look at my specs below and advise me if my bios is incorrect?

many thanks.

my gpu is ati hd4670 by the way so its up to the job.

i checked with bios and it reports memory speed is 333 mhz.

More about bios speed
  1. With all 4 ram slots filled, some 939 boards will only run at 333 speed. This is a limitation of the motherboard chipset. The board uses the slower speed to keep the system from crashing. With only 2 slots filled, you won't have this problem. You can try manually setting the ram speed at 400, but you may have to slow the timing settings. The higher the number for tras, cas, etc. the slower the ram runs. But you really won't notice the difference in real world applications.
  2. thats very helpful. thanks
