Socket 423 to 478 Conversion

[demon_wolf]

Hi all,

I thought I would do this as there is alot of information in different forums about this process and thought it would be easier if it was all in one. Thanks to those that posted links in other forums.

First, visit this site:

http://www6.tomshardware.com/cpu/200...apters-03.html

It gives you the basics on the conversion.

Next, visit this site:

http://www.upgradeware.com/english/p...patibility.htm

This gives you a compatibility chart. If your board is not listed here, then email them at this address:

support@upgradeware.com

They will be able to help you out.

As for adapters, here are a few links:

For the standard adapter:

For the special adapter(required by some boards):

Also here is another link:

or their EBay ID: fortunekeeper

From their EBay auction listings:

Socket-478 vs. 423: This translates into one main difference. The new 478 model will allow for a much more densely packed arrangement of pins known as uPGA, or micro Pin Grid Array, interface. This simply results in the capability of the CPU to be much smaller and the space occupied by the interface socket on the motherboard to decrease as well. The entire Pentium 4 line will be available in both Socket-423 and 478 versions, although eventually all of the processors will be the more advanced Socket-478.

This 423-pin to 478-pin CPU Socket Converter works for both 0.18-micron Willamette and 0.13-micron Northwood (the adapter is equipped with an independent voltage regulator), which makes the novelty a universal headache remedy for the owners of old Pentium 4 based systems. Newer Socket-478 motherboards will still primarily be based on Intel? 850 and 845 chipsets so there isn? much of a reason to upgrade boards other than to gain CPU support for Socket-478 processors.

This adapter has a built in Voltage Regulator.....no switches to change...different from those adapters at strattoncomputer.

Hope this helps some people out.

Thanks jme.

I've found several more suppliers of these adapters, will put up the links once I get a little more time.

Thanks, demon. I'm interested to see if I can find these for any cheaper than you've already posted.

Here are several more suppliers of the adapter, and I managed to find a good set of instructions:

http://store.yahoo.com/amamax/mbecsp4pcuadapt5397.html
Amamax $19.00 free shipping.

http://www.powerleap.com/PL-P4N.html
PL-P4/N adapter with heatsink and Fan: $49.95.
This one is more pricer than the rest, but it comes with a new heatsink and fan.

As for the instructions:

Please be aware that these instructions are for adapters with Voltage Switches on them. Adapters without Switches(Self Setting) are the same, you can just ignore the Voltage adjustment part.
