I just up graded an older computer with a 2.4 Ghz CPU. The boot screen shows it is only 1.8 ghz. But the Device Manger shows 2.4 ghz. Anyone have an idea why?

Would you belive if this happened to me once, on the second computer I ever owned. I remember it was a 300Mhz Pentium II computer but it would show up as 1700Mhz.

The boot reading is most probbally the correct one. But to double check, update your bios. If you are still uncertain, then go ahead and remove the CPU and see what it reads.

Hope this helps.

perhapes ur motherbaord cannot support the full FSB of the new chip and is running at a lower FSB so it can run

say 800 instead of 1066

as FSB 800 = 200 bus and 1066 = 266

assume u have a multiplier of 9

266 x 9 =2600

but u can only get

200 x 9 = 1800

i think this could possibly it

what do u guys think ?

Depends on what chip you have and what motherboard you have. Could be the FSB isn't fully supported, and this is downclocked, or some power saving settings that force a lower multiplier on boot for whatever reason. Could also just be an incorrect BIOS reading. List your Specs. Also what speed does CPU-Z give you?

Yup, I forgot to mention that. You should download CPU-Z From CPUID.com and check what the real CPU ID is.
