Dell 8200 CPU UPGRADE

Hi all, I have a (year old) Dell 8200 with an Intel Motherboard and a P-4 2.4 ghz w/533 FSB.

I have just purchased an Intel P-4 2.8ghz for 533 FSB, but when installed, the PC will not boot, on power-up, the system doesn't respond.  Do I need to re-set the CMOS in order to get it to work?

I am well versed in PC technology, and this is the first Processor problem I have had, the chip works in another newer PC.  I seem to be overlooking something, when I put the 2.4 back in, all is well.  The Motherboard specs tell me that it will accept a 2.8!

Any Suggestions??

Thanks in advance!!

your bios may have optimized settings for the 2.4 chip.
Try setting the CPU settings back to the setup default in the bios.

Are you sure that the 2.8 is 533 & not 800?

ASKER

CPU settings are at default, the chipset is an 850E

FSB is 533 w/PC800 RDRAM (Rambus) 1 gb

Hi philby11, yes it is a 533ghz Processor (Boxed 2.8/533ghz)

chicagoan the BIOS is A09 and there are no diognostic led's neither on the back of the PC or on the Motherboard.  Although Intel's site says the motherboard will accept a 2.8 processor if the chipset is 850E, but will not if it is an 850, I have doublechecked the chipset on the board, and it is the 850E.  I did re-set the jumpers to clear CMOS settings, but still would not boot, so I could not get into BIOS with that chip installed.

The motherboard I used to test to see if it worked, was an Intel 875 PERL and it works fine on that board.  I also ran SiSoft Sandra and it also reports an 850E chipset.

This one has me stumped!!

Might be time to make a pot of coffee and call Dell

Hi StealthMullet, yes it does revert back to full operation, but I tried it in a third PC and it still works. The only conclusion I can come to is, there has to be a problem with the board in the Dell, possibly because it is OEM for Dell.  

For the price I paid for the Boxed 2.8, it is not returnable if the processors works (purchased on the Internet), so yesterday morning I bought an Intel 875PERL board locally that is returnalble if it is a no go, I rebuilt the PC with the 2.8 and it is working like a champ.  So, I called my Son who has an older P-3 733 and put my old board and chip in his PC, so we both have an upgrade, and now I am upgradabe to all the way to Intel's best chip (P-3.20 HT  Extreme w/L3 cache of 2mb).

I will have a Mod change the title to Dell 8200 CPU Upgrade, so this might help other Dell users, and have more points than I will use, I will split the points to all who posted your help here.

Thanks all,

W~
Have fun with 'em...thanx...T
