Intel P4 2.26GHz 478 Pin Mod?

post #1 of 7
Thread Starter 
So, i was offered a few pc's for free, so i said to myself "why not?". They all came with a Socket 478 Northwood P4 @ 2.26GHz. Now i was wondering if i could pump the fsb up a bit via a pin-mod? It currently runs at 133x17 (533MHz FSB, 133 Bus Speed) Cooling is not a problem as it is running very cool. It's not custom built pc's. Their made by Compaq. I've searched around google but could only find out how to pump it from 400 > 533FSB. I've also tried to use SetFSB and ClockGen but it seems the chipset is not supported (Intel 845G)
Any ideas?

there is a mod for 667FSB.. though its not for sure if it will work properly unless its a mobile CPU..

Heres a pic of a mobile of mine: running stock clocks at a not-so-stock FSB pin-mod from 100-133fsb ... overclocked from there

That's cool. Unfortunately, this is not a mobile P4. I looked at my PLL yesterday aswell, but it's not supported or mentioned anywhere on the net being overclocked using ClockGen or similar. It's a W320-03H (Cypress CY632568) Unless someone finds a solution or knows, i guess i'll gonna install a 2.8GHz P4 Northwood @ 533MHz FSB.

Yes, installing a better CPU is your best bet. If you can find the 3.06 Ghz Northwood with 533 Mhz FSB for sale that would be ideal because it's the only model with 533 Mhz FSB that has Hyperthreading, which is very useful nowadays.

Ah, the old P4 which had HT. I used to love these. I have been offered a 2.8GHz for ~$9. It's supported by this PC. But i don't know if this motherboard accepts the HT version of it. (FYI - It's a Compaq Evo D510 SFF) The 2.8GHz P4 is supported since some versions of this PC shipped with it. So the best choice would be to install the non-HT one.

Oh, ok, I guess that is the safest choice then. I just searched on ebay (UK) for the 3.06 socket 478 P4 and found quite a few. They are selling for good prices, cheapest being £8.99 (only UK though) and from Hong Kong with free shipping starting at $15.99 USD.


Edit:

Just found this on the HP/Compaq page for your model:

NOTE: * Hyperthreading Support - Systems shipped after February 1st, 2003 will include support for Hyperthreading. To take advantage of Hyperthreading, the system must be configured with a minimum processor speed of 3.06GHz. HP has performed qualification testing under both Windows XP Home and Windows XP Professional. HP strongly recommends that customers upgrade to the latest version of the Microsoft Service Pack for these operating systems. This will ensure the best possible user experience.

You can check to see if your system qualifies. There should be date somewhere on the computer case.

I couldn't find a date on my case. What i could find was a date on the motherboard. It's made somewhere in-between 2001-2002. So i guess HT support is out of the question. Also, i just tested a 2.8GHz in it. Guess what? It seems the bios doesn't even support it. I upgraded the bios to the latest, but unfortunately, even though the release notes mentioned "Revision D support" which this 2.8GHz P4 is, it still couldn't run properly. It ran at 99x17 instead of 133x17. Then i read that you needed another bios from another model. So i downloaded that, and of course it requires you to use a floppy to update the bios. I even tried to make it run from USB but then the CMD Prompt would spit out that the program was trying to access the "HDD" directly. So that was out of the question aswell. So.. i'm out of ideas here. Maybe the 2.6GHz model will work properly, but i don't know. I don't see why that P4 wouldn't work. It's a Northwood with 533FSB, which should be 100% compatible. Gargh! Very frustrating.
