Fixing a Dell 4550 A08 bios system

[Oyeve]

OK, My friend has a Dell 4550 series PC, came with a 2ghzA p4 chip, it is 400fsb. Her HD is so overloaded and full of every virus, trojan, spyware known to man thanks to her kids. 🙂, anyway, I will eventually wipe the HD and reinstall the os but I wanted to upgrade her slow 2ghz p4 with a spare 2.6ghz p4 I have laying around. I noticed her bios was on ver A01 so i flashed it to A08. I put the 2.6ghz chip in and the bios sees it as 1.3ghz, so I figure ok, her old chip was a 2ghz 400fsb NON-HT chip, this 2.6ghz is 800fsb and has HT. I boot up and the OS sees it as 2.6ghz but tells me its running at 1.3ghz. I task manage and HT is running as it should. Is this chip not compatible to work in full 2.6ghz? Could having pc2100 DDR affect the speed of the chip in the bios? As you know, the bios options in Dells are very limited. Any help would be appreciated.

That is weird

According to the specs, it supports up to 3.06 @ 533

Intel® Pentium® 4 microprocessor that runs at 1.80, 1.90, 2.0, or 2.20 GHz internally and 400 MHz externally; or 2.26, 2.4, 2.53, 2.66, 2.8, or 3.06 GHz internally and 533 MHz externally

Actually, the 2.6ghz chip I popped in there is 800fsb. I just found out because I have 2 of them and its 800fsb. But shouldnt it drop down to 533 on the system? Or is it locked at 800fsb and the system kicks it down to 400fsb, which would somewhat explain the 1.3ghz.

2600 @ 800 fsb would be 200fsb quad pump, multipler of 13 = 200*13 2.6Ghz
if it drops to 533fsb, it should be 533 /4 = 133fsb * 13 = 17xx mhz.. or 1.7ghz..

the 400fsb would make sense.. 100fsb * 13..

Thats what i figured, oh well, 2ghz goes back in.
