Upgrade to Cedar Mill

[Larry]

I have a compaq presario with a socket 775 intel p4 chip 2.8, 520J
(prescott)
the mother board is an asus PTGD1-LA,
Can I put an intel Cedar Mill cpu 3.4 intel chip in it.

The socket for the Cedar mill is the same, socket 775 but I wonder is
that all
I need, or do I have to upgrade the motherboard.

Thanks in Advance,

Laurence

You may need to flash the BIOS, do you know what motherboard it is?

Unless HP/Cpq has a suitable BIOS upgrade, it probably won't matter - with
most OEM systems, the OEM gets to decide if the BIOS is upgradable. Even
if the mbrd is close in specs to some retail mbrd, there are often hardware
customisations which make the retail BIOS unuseable.

I'm afraid you're looking at a new motherboard here. The board you
have is based on an i915 chipset (either the i915P or i915G, depending
on the exact model of system you have). This chipset will not support
any dual-core processors.

But isn't a Cedar Mill just a single core 65nm CPU in the P4 6xx
series?

I checked at the HP site on this.
Here is the spec on my motherboard.

* Northbridge: i915G graphics and memory controller hub
* Southbridge: ICH6 Intel I/O Controller Hub 5

Isn't the cedar mill a 3.4 Gz pentium 4 a single core processor?

I think that the issue is, can I replace a prescott pentium 4 with a with a cedar mill pentium 4.
The cedar mill being a 65nm type as opposed to a prescott which is a 90 nm.

I would like to get a faster cpu and also reduce the temperature of the cpu,
since I am going for a higher clock speed. I assume that the 65 nm cedar mill would
be cooler.

LOL, I think you're right, I'm getting my Intel codenames confused
again (I mixed up the dual-core 'Preslar' and the single-core 'Cedar
Mill').

In this case, chances are that the Cedar Mill chips should work on
that board.

Depends... BIOS support, voltage, current... The best place to look
is the mobo manufacturer site.
