Hi, I have a query for anyone who's interested: My single 512MB stick of 333MHz RAM is sat in my ASUS P4S533-MX (533MHz FSB) mobo next to a 2.4GHz Celeron processor (100MHz FSB). In my BIOS (rev. 1004) the RAM speed and timings are correct (I presume: 2.5-3-3-7). However, when I check mt speed in XP using Everest it tells me that the memory speed is 166MHz! I should add that Everest also reckons my CPU is running almost 20C cooler than my BIOS says. When I benchmark my RAM with Truebench it comes up at 42,9496,6290Mbps, does that sound like 333MHz or 166? Can anyone tell me what is going on? Am I just being paranoid? Forgot to mention that the timings are given as the same by Everest as BIOS.
