My RAM is rated at 1066. In my bios, when I select DDR-800 and then try and clock the FSB up, I believe I hit some memory controller limits and I can only get to about 950 on the RAM before I start getting issues.
When I select DDR-1066 and everything seems fine but I manually input the timings 5-5-5-15 in my bios yet next time I boot into the bios, the bottom of the ram info screen says my timings are 5-3-3-3 even though my manual selections still state 5-5-5-15. Also, when I load up memtest from a boot cd, memtest reports my timings as 5-3-3-3 and my ram speed at 937 or something like that. Yet, when I load into windows and open CPU-Z, it shows 5-5-5-15 1066.
If I manually select 5-7-9-27 as my timings, then the BIOS and memtest display 5-5-5-15. Anybody know why and which settings my computer will actually be using?
