Socket 478 question

Working on updating an older system to keep it in use. No real heavy gaming on it currently.

I've searched and noticed that there seem to be some core 2 duos that were offered for the socket 478?

What would be the best processor to use in this 865PE board?

Thanks in advance.

Core 2 Dou on a 478 socket? are you sure? Core 2 Dou is TOTALLY different than the P4 w/hyperthreading. The P4 w/Hyperthreading = 1 core but could process 2 threads at the same time. It would show up as 2 logical cpu's. The first Hyper Threader to hit the market were the Northwoods using Rambus (RDR) memory from what I can recall. There may be some versions that run on DDR memory. They may be hard to find. Your best bet may be E Bay for something like that.

Core2duo's will not work in that board. No dual core cpu's for that matter. The highest an 865PE motherboard will take is up to a 3.4GHz P4 processor. Unfortunately they are signifigantly more expensive than today's dual-core cpu's and much slower.

The highest i'd put in that board is a 3.0GHz cpu if you can find one cheap.

That's the reason I was asking. I did a search under the CPU section for duo and 478 on pricewatch and from reading the descriptions, it appears that there were S478 duos.

The Search

So the fastest available processor for a S478 board is a 3.4, correct?

The ""Core Duo"" procs were s478 - AFAIK they were all mobile varieties - Pentium Ms or ""Yonah core""

Whether it would work in your mobo is another question - and they are really expensive these days if you can find one ...

And to add, I would look up Intel, find your chipset and see if the CPU that you are looking for is in the specs for processors supported.


Edit: Assuming your mobo is an intel. If not go to your manufacturer to find out what processors are supported.

There were not. What you are seeing are Core Duos (no "2", they came before the Core 2 Duo) intended for laptops, which used a socket that had 478 pins. However, their socket (known as Socket M) was not compatible with the desktop socket.

What would be the best processor to use in this 865PE board?

It depends on your definition of "best". AFAICT you can probably run any of the Northwood Pentium 4s and most of the Prescott Pentium 4s, which ran up to 3.8 GHz (the 670 and 672). There are some indications that you can only go up to 3.4 GHz with that chipset; consult the documentation available from your motherboard manufacturer.

In any case, I would imagine the top-end parts are horribly expensive. My suggestion would be to buy something more modest, or start saving up for a motherboard upgrade. Moving to Socket T and a Core 2 Duo or Core 2 Quad would be a large speed improvement over most any Socket 478 part, even assuming you buy one of the older, cheaper processors.

The Pentium M predates the Core Duo series. All Core Duos (and Core Solos) use the Yonah core. All of these series used 478-pin sockets ("Socket 479" for Pentium M, "Socket M" for Core Duo/Solo), but were not physically compatible with Socket 478 and were not electrically compatible with each other.

This topic would probably be better off in the General Hardware section.

Anyway, what is your budget and what are your intended uses for the upgraded box? With that info we can make a better recommendation for what to upgrade.

These days it often makes much more sense to replace the older parts (cpu/mobo/ram) entirely at lower cost than trying to find an old/obsolete processor upgrade.

Recent price examples:
e2180 $75
IP35-e $65 after MIR
2x1GB DDR2 $30 after MIR

This would give you a system upgrade for $170 that even at stock speed would completely destroy any P4 chip you could possibly drop into your old system. Plus has 2GB ram compared to an old P4 system that probably has 512MB or at most 1GB.
