Just changed M/B to Gigabyte GA-7N400 Pro 2, new HDD installed. XP Pro, Athlon XP2800 Barton Retail boxed. Have been reading some threads but cannot figure out how to get correct clock speed for CPU. On boot-up it reads 1254mhz, installed Easytune 4 but options for CPU are greyed - out. Uninstalled and changed to Easytune 5, this is even worse! Gigabyte site says this CPU is fully supported so why does Easytune not allow multiplier changing and how can I get my correct CPU clock speed back? (until last night it was quite happy to pose as XP3200 on a £20 PCchips board!) Regards, Coxy.
