Hello, I have an 8gpnxp-duo with 2 corsair DDR2-PC5400 Modules(2X512Mb-matched pair). In the manual Gigabyte discribes how to set the memory frequency to 3 times host clock, but in my bios (F5) I only see 1.66, 2.00 2.66 and AUTO. When set to AUTO the frequency is 2.66 x hostclock(200Mhz) and not 3.00 times. The memory SPD reads 333Mhz tiomings 4-4-4-12. So the memory supports 666Mhz, but I can't even get it to 600Mhz while the FSB=200. Does anyone know how too solve this problem? The Gigabyte support site tells me that they don't support overclocking! frans
