that's becuase your cpu is running with a rare FSB -- 2800mhz = 200 * 14
you mother board is using a 150 mhz FSB then
150 * 14 = 2100 approx 2'09 ghz

what motherboard are you using?? maybe that's the problem. try to update the bios or change the FSB manually (not recommended if you're not an expert)

| the motherboard is an Intel Desktop board D845WN. you think it can also be that the mother board doesn't support that cpu speed? |

it supports fsb400(quad100) p4 only, so the fastest CPU for it is a certain model of 2,6 Ghz Northwood,
Your Northwood is probably 2,8 Ghz with 533(quad133) Mhz FSB, so it runs at 2800/133 x 100 Mhz = 2100 Mhz. |

| not a question of bios, its a chipset question. |
