Did you ever upgrade to that socket 478 3.06 processor?

Did you ever upgrade to this processor:



I was reviewing this thread here:


I have the exact same motherboard (07E8h), in a Compaq Presario 6027us, so I'm thinking if it worked for you it will work for me perhaps.

But my bus speed is 400mhz where as this processor is 533mhz, will that be compatible with my motherboard that you know of ?

I don't know whether the bus speed is limited by the motherboard or depends on the processor.

Thanks for any info!

Also, I found this neat little site from asus, it's a Power Supply Calculator.


wow, just looked at my power supply it's 220W MAX hahaha, wow this should be fun.

Even with my current setup, it says my computer was shipped for retail sale with a psu that is too low for what is contained.

I have:

p4 2.0ghz socket 478 400mhz

NO video card (onboard graphics are decent so i don't need one)

2gb of ddr pc-2700 ram (1 gb modules)

1 Dvd/CD-ROM

1 Dvd/Cd-RW

1 usb device (wireless receiver)

0 PCI slot expansion devices

3 Fans

I really hope I can add just this one PCI soundcard (layla 3g) for recording my synths and drum machine, and get away with it with the 220W power supply, since I've had no problems whatsoever, and this is just one more device that has a max pull of 10 Watts.

Anybody have any opinions on that ? ... lol

There are very few 478 motherboards which do not support a bus speed of 533 MHz, so that CPU should work. However, I would question the purpose behind upgrading such an out of date system when a brand new up-to-date system can be built for under $300 if you can reuse an old case and hard drive.

I'd can't wait to build a computer at some point in the future, but i need help as I've never done it before, I can't afford to screw anything up.

I thought it was a great idea to upgrade, seeing how the processor is only 50 bucks! and it's upgrade of an entire 1ghz in speed from 2.0 to 3.06, plus I like this motherboard it has 3 pci slots, onboard graphics are fine, I can install firewire card and a good soundcard if the psu will support it, if the psu is too low then i will have to find a way to build a new computer, but I don't like ordering a bunch of parts over the net, something is bound to be doa and have to be returned on my dime and with my limited knowledge I might not be able to determine which part is defective once I put it together, costing more money in diagnostic fees.

btw, how many Watts does your average PCI firewire card (say 2-3 ports) use ?
