Processor Upgrade & Clock Speed
Hi
I have a Dimension 8200 2GHz System which I am looking to upgrade to a 2.4GHz. At the moment the processor is set at a clock speed of 2GHz - as it should be. I have placed the new processor into the system and Windows Device Manager recognises it as a 2.4 Pentuim 4 Processor - which is fine. However the clock speed is set at 1.8GHz and I cant seem to change it.
Ive been into the bios and the bios is recognising the clock speed as 1.8GHz also. There doesnt seem to be an option where I can change this.
At this rate Im better off with my 2GHz processor as it was giving me a 2GHz clock speed as well!! How can I get it to recognise the correct clock speed of the 2.4GHz processor.
many thanks for your help in advance.

It sounds like you have the older 8200 motherboard with the 850 chipset. That chipset only has a fsb speed of 400 mhz. The 2.4 mhz CPU is a 533 mhz chips and thus runs at 2.4 X (400/533) = 1.8 mhz. Later models of the 8200 use the 850E chipset which can run both 400 mhz and 533 mhz CPUs. For more information, see

and/or visit the Dimension - Upgrade Hardware forum where 8200 upgrades are discussed quite frequently.

If I purchase a faster processor but still a 400MHz will it work ok?
Thanks

Hi
Thanks for the info. So basically if I put the 2.4 Processor in the clock speed will be slower - so Im better off leaving the 2GHz in my system?
Thanks

Yes, 400 mhz CPUs will work at their rated speed. Please take your discussion to the Upgrade Hardware forum where you will find many other users that have upgraded their 8200s.

looks like u purchased the wrong processor. You have a 2.4 B which is supposed to work on 533 mhz FSB systems. This processor has a multiplier of 18 and its supposed to work like this:
133*x18 = 2394 = 2.4Ghz
When u put it in your system however, you get this:
100*x18 = 1800 = 1.8Ghz
(* the 533 bus is actually 133x4 (quad pumped) while the 400 bus is 100x4 (also quad pumped)
So, you should return the processor and purchase a 2.4A (400mhz) processor Or put your old one back in. The 2.4A may be hard to find these days, i havent looked in a while. Good luck.
