Over Clocking Pent 4 2.0 400fsb

[RJPerset]

I have a pent 4 2.0 ghz with 768 Ram and a ECS P4s5a 1.0 MB. The board says its a version 5.1. I purchased a 2.8 chip/533 fsb. When I installed the chip it read as a 2100ghz. Going into BIOS,
I found under CPU PnP set up the following:
CPU Type Pent 4
CPU/Dram speed 100/100 The right number is adj to 133 or 166
CPU Locked
Cpu Freq 100
Dram Freq 100

I was told by the Tech at ECS that I can over clock to 133 for the 2.8 chip. Since I can only adjust the one number is that all I do?
Any help would be appreciated as I am a noob at this stuff. Thanks

You still have your FSB set at 100 MHz which is stock for your old 2.0 CPU 20X100=2000 MHz). But the new 2.8 CPU uses 133 FSB (21X133=2800 MHz). Just change the FSB to 133 and you'll be fine.

ATTEMPT MADE BUT FAILED

Ok I put the 2.8 533 chip in. I even set jumpers to erase memory.
Set CPU PnP (right side is only adjustable) to 133 can still do 166.
Computer recognizes the 2.8 chip in, but it still registers as a 2.10ghz.

From the info on ECS website, your motherboard only supports 400fsb. Your processor will only run at 400fsb. With a multiplier of 21x100fsb=2100

Stock, the board only supports 100Mhz FSB chips, as said above. The tech support apparently told him that overclocking the board would be possible though.

The end result would then be: CPU at stock speed, board overclocked.

What you (OP) need to do is to adjust the CPU frequency (speed). You may have to enable adjustment of this speed first by setting "manual" first. The other 100/133, 100/166 setting is about RAM speed, which is given relative to FSB speed. I would keep it as low as possible initially, as we don't know how high it will go.
If the board makes it to 133Mhz FSB (CPU 2.8Ghz), then you can see about increasing RAM speed.
