All P4's have a locked multiplier.

Did you check your board specs before you changed CPUs? There were at least 8 different PCB versions of the P4VMM2. Some supported up to 400MHz FSB only, others supported up to 533MHz FSB. My guess is you have an early model. And since both the 1.8GHz/400 & 2.40GHz/533 use the same multiplier (18x), you'll gain nothing on a 400MHz FSB board.

This will show you where to look for the PCB version:

based on the link you given me: my mobo is p4vmm2
FSB533: do you have any idea?

Can't help you if you don't give the PCB version.

ECS P4VMM2 (PCB:7.1/7.3)

"ECS P4VMM2 (PCB:7.1/7.3)"

OK, that's what I needed to know.

Unplug the power cord & open the case. Look for jumpers labeled JP1A1 & JP1B1...they're roughly in the center of the board, just above the AGP slot. To change to 533MHz FSB, move the jumper caps to the following pins:

JP1A1 = pins 2-3
JP1B1 = pins 1-2

Close up the case & boot up.

The manual for a version 7.3 board...the connectors are the intel standard.


On/Off switch connects to pins 6 and 8; they're the two next to the empty pin.

10 - 9
8 - 7
6 - 5
4 - 3
2 - 1
