I setted the frequency of the DDR 400 memory at 200 MHz on BIOS. But after saving, exit, etc. the next day on POST appear only 166 MHz (BIOS retained the value of 200 MHz !). Why ? Which is now the true memory frequency ? The parameters are: * RAM: a) 1 Gb, DDR 400 MHz, cl. 2,5, 184 pin; code MPXD42F-D8KTB (Kingman) b) 0,5 Gb, DDR 400 MHz, cl. 2,5, 184 pin (TwinMos) * Motherboard: EPOX code EP-8NPA7I, rev. 1.x, nVidia nForce4 4xchipset * BIOS: Phoenix Award, 2006 (2005 ?); the default setting was 166 MHz (Auto) but I modified this setting to 200 MHz, thinking that the memory tolerate this frequency by design. Thank you very much.
