I currently have a Pentium 4 3.4ghz CPU

I'd like to upgrade to the best quad core cpu that this machine will support.

Here are the specs:

Standard L2 Cache: 2 MB, 1 MB or 256K depending on processor

Chipset: Intel 945G Express

CPU Bus Speed Supported: 533 MHz, 800 MHz (Processors with a 1 GHz FSB are not currently offered on these models)

Standard L2 Cache: 2 MB, 1 MB or 256K depending on processor

CPU Socket: LGA775 Socket

Thanks in advance.

That is a Pentium D that I mentioned in my first post. You are better off buying an entry level laptop in the $200 range. It will be several times faster than a Pentium D based system. And even though it 'should' work the only way to know for sure is to contact HP and ask them if the motherboard BIOS include support for that specific processor.

According to this: ( page 4 )

The DC7600 was available with Pentium 4, Pentium D and Celeron processors only, no Core2 support at all as I suspected. You would be "upgrading" a 10 year old processor with another 10 year old processor. Any time and money spent on this would be wasted unless you are setting this up as an extra box...

There is no upgrade for that old motherboard. LGA 775 has been a dead socket since 2009 and even then the later processors that fit the socket were not supported by the 945G chipset. It might support a dual core Pentium D but they were just 2 Pentium 4 chips on the same die and were crap even when they were new. It certainly will not support a quad. You're talking about 10 year old technology here. An Atom netbook processor at 1.3Ghz is roughly equal to a ( dual core ) Pentium D 3Ghz. Literally the cheapest budget setup on the market new today will be many times faster than that terrible Pentium 4.

Time for a new computer.

Intel Core 2 Duo
E4300 - HH80557PG0332M / BX80557E4300
E4300, 1.8 GHz, FSB 800 MHz, L2 2 MB
E4400 - HH80557PG0412M / BX80557E4400
E4400, 2 GHz, FSB 800 MHz, L2 2 MB
E4500 - HH80557PG0492M / BX80557E4500
E4500, 2.2 GHz, FSB 800 MHz, L2 2 MB
E4600 - HH80557PG0562M / BX80557E4600
E4600, 2.4 GHz, FSB 800 MHz, L2 2 MB
E4700 - HH80557PG0642M / BX80557E4700
E4700, 2.6 GHz, FSB 800 MHz, L2 2 MB

You appear to be limited to Core2Duo. It would be an improvement over your current CPU, and would be sufficient if you just do web browsing, word processing, or other light CPU tasks. You could probably find them (used) cheap on an auction site.

He has an HP that shipped with a P4. You can honestly say their BIOS supports all those chips? OEM upgrade paths are generally nonexistent just due to lack of BIOS support. Even if it wasn't an OEM you would need an exact motherboard make and model to be certain of supported CPUs. "Official" chipset support back then was hit or miss.

Either way he asked for a fast ( or any ) quad and it isn't happening with what he has now.

You would be "upgrading" a 10 year old processor with another 10 year old processor. Any time and money spent on this would be wasted unless you are setting this up as an extra box to run Windows XP or 98 for old games or something. Maybe something for the kids to experiment with and learn how to build a computer. If it's your primary computer it's not worth it. You are much better off saving any money you had for this and putting it toward something new or even something used and 4 or 5 years old instead of 10 years old.
