I just powered up my new computer for the first time. So far so good. I went into the bios and started to configure the ddr2 settings. Everything is set to auto and the numbers all look correct except for one. The memory is Corsair ddr2 800 xms 5-5-5-15 2t. The computer is reading it as 5-5-5-18 2t. How do I change the 18 to 15. There is a whole list of different functions under the ram sub-menu. What setting do I change to get the correct #'s. Thanks
