CPU and Memory Upgrade

Specs: Microsoft Windows XP Home Edition, 2.8 GHz / 1015 MB
I have an old Compaq S6100NX w/MS-6577 motherboard running a Celeron 2.8, w/350 watt PS, 1 GB memory, PNY 8400GS and a Creative Xtreme gamer sound card.

I want to upgrade the CPU to a P4.

The 6577 has a Socket 478 for the Intel P4 Williamette and Northwood processors and supports Intel Pentium 4 processor up to 3.06 GHz. Also, Intel 845GV Chipset - FSB 400/533.

The 6577 spec sheet also states Maximum memory is 2GB without ECC (the PC manufacturer's recommended maximum memory may differ).

So far, so good... I found an Intel P4 2.8GHz 533MHz 478pin 1MB CPU.

So now I have 3 questions:

1) Is the P4 about as good as it gets for this socket and FSB?
2) Do I need to do anything to configure the FSB for the 533 Mhz?
3) Compaq says 1 GB max memory, but can I increase the memory to 2GB (jumper, etc.)?

Thanks for the help

IMHO, an old Socket 478 board with no AGP slot is not worth upgrading.

"I found an Intel P4 2.8GHz 533MHz 478pin 1MB CPU."
That CPU won't work because it's a Prescott (as indicated by the 1MB of L2 cache). The Prescott's high current draw can damage older S478 boards.

The fastest CPU you can install is the 2.8/533/512KB (Northwood) P4. The 3.06GHz may work, but you won't be able to use Hyper-threading.

edit: I just took a closer look at the spec page, and it appears that your board supports Prescott-based Celeron D processors (but not Prescott P4s, as they draw more current than Prescott Celerons). However, a 2.8GHz P4 would be faster than a 3.06GHz Celeron D.

"2) Do I need to do anything to configure the FSB for the 533 Mhz?"
Most OEM boards (Compaq/HP, Dell, etc) usually do all of that stuff automatically.

"3) Compaq says 1 GB max memory, but can I increase the memory to 2GB (jumper, etc.)?"
According to HP, your board supports 2GB.

Your system will never be a decent gaming machine no matter how much money you throw at it...I assume that's the purpose of these upgrades?

Thanks for the help. I am disabled and just can't afford a state of the art rig. I bought half-life when it first came out, it does does a decent job with the online game rooms. Just want to get a little more life out of the old hardware for Killing Floor and Android SDK development.

Now I understand the code-names for Intel core development, with the Northwood following the Williamette and Prescott following Northwood.

The processor is probably not the bottleneck. The graphics you have suck and can't be upgraded with anything other than possibly a PCI based video card.

@OtheHill: Did you see that I have a PNY 8400GS 512MB PCI? I tried an eVGA 9400GT 1GB PCI, but could not resolve device conflicts, even working with their staff, using Driver Sweeper, etc...

I think I'll go with a P4 2.8 ($45) + another 1GB memory ($45 - for 2GB total).

Sorry, didn't read the entire thread because I mixed it up with another similar one with integrated graphics and no graphics slot.

@OtheHill it's cool, all good. I am learning way more than I wanted to re: Intel cores, silicon generations and sockets to get this far. If you are as OtheHill as I am, you probably know what cmkrnl means. lol
