Pentium vs. Celeron

[dieselmb]

I have a MoBo (ECS P4VXD+), socket 478, that supports Pentium 4 up to
2.8Ghz.
It does not have the AUX 4-pin +12V power socket for the CPU.
I try to get it to boot with a Celeron 1.7 Ghz but have no success.
Does this CPU require the AUX power?
What I get is 3 beeps (bad memory) if I set the clock speed junper to
133 Mhz.
If I set it to 100 Mhz I get nothing.
Memory I tried is Samsung 256MB DDR PC2700 or 128MB DDR PC2100, jumper
is set to 2.5V.
The board ran for years with the P4 and the PC2700 memory.

No. Not if the motherboard does not have it.

What is this p4 you mention? and Does it still work?

Keep in mind that ECS is an El Cheapo manufacturer, so don't try too
hard to get it working. Not worth it.

That does not compute, there is a P4VXAD+ tho.

That isnt a cpu specific, its determined by how the motherboard
generates the Vcore voltage for the cpu. That was done from the
5V rail at one time and then later from the 12V rail on that 4 pin connector.

Sorry, yes it is a ECS P4VXASD2+ .
The manual says: support for Pentium 4 up to 2.8Ghz.
I used this board for several years with a Pentium 4, 2.4 Ghz and DDR
PC2700 Samsung.
Some time ago I upgraded and kept the board and RAM for a spares.
A friend fried his board (eMachines) and I try to get him going with
my spare. The Celeron is from the eMachines.

A Pentium 4, 2.4 Ghz and yes it still works, but in an other machine.

Black and silver Emachines often kill their processors (pretty much
the only computer to do so on a regular basis). Also the motherboard
*and* power supply. And sometimes even the RAM. If you want to fix
this: replace the emachines Bestec power supply, whether or not it
works. Emachines power supplies kill the motherboards.

Reviving a dead emachine is a multi-organ transplant project. You will
have to test the components individually to separate the live ones
from the dead ones. Sorry for that news. The good news it the cds and
hard drives are usually fine.


So: try the celeron in your known good board. Also try your p4 in the
ecs machine (if supported)

ECS boards can be very picky and possibly a buggy bios. You
might try unplugging AC then clearing CMOS. You might also
check on a bios update, though of course you need a working
CPU in to update it (and to be sure it's stable enough to
flash without undue risk).

I knew the PSU problem of eMachines, and that they take out the MoBo.
Didn't anticipate that the CPU bites the dust also.
I got the PC going with only the case (from which I removed the
eMachines lable) and the HDD, FDD and CD-ROM drives remaining.

Even those that currently work should be watched carefully. They
would have been over voltaged if the motherboard has been killed
and they dont necessarily always die immediately on an over voltage.
