Hello, can anybody help me? I re-install my operation system (now install XP) and my central processor (Core2Duo 6420) now work on low frequency. Everest show only 1.6 GHz and this then I playing in 3d-game or watching HD-movie or archiving some files. That is not some program presets/profile or power savings mode, because i install only drivers, Everest and Crysis. What happened? Who guilty? Early processor work on default frequency - 2.13 GHz and I didn't change any accessories. Please help me. P.S. my configuration: CP - DualCore Intel Core 2 Duo E6420, 1600 MHz (8 x 200), MB - Gigabyte GA-945GZM-S2 (3 PCI, 1 PCI-E x16, 2 DDR2 DIMM, Audio, Video, Gigabit LAN), Cheapset - Intel Lakeport-G i945GZ, Graphic adapter - NVIDIA GeForce GT 240 (512). Thanks For Attention!
