Keep the timings loose for the time being...once stable put it back to 4-4-4-12 if you can.
For the memory frequency it is based on your FSB frequency. At 200 with a 2.0 multiplier (all 2.0 means is 1:1, personally for the 800 FSB chips I dont use it) it would make the Ram 400 which is low. Auto will do 4 times so 200 x 4 = 800 and 240 x 4 = 960. For the time being do a multiplier that keeps the Ram at or below 800 and then once done with the CPU do Ram overclocking if you want
