can someone explain this to me?

[Uranium]

How come a new 1800+ tbred OEM can cost as much as a 2800+ Barton?

[nark]

how is a 1800+ t-bred new? The cpu is like 3-4 years old at the very least.

Plus, it has to do with supply and demand. There is still a very small demand for athlon xps, while the supply is nearly nonexistent.

[Uranium]

by new I mean unopened, not used.

I know it is old, but a Socket A MB is soon going to be coming into my posession that takes up to a 2600+

u should look for sempron too (s478) ... they are exactly the same but just different rating and should be cheaper ... or maybe you can find one here in the trade section

[Uranium]

board dosen't take Semprons. It's an old board. It's a SDR board. I know that sucks, but it's better then the 400mhz K6 I'm going to be building for someone

Hehehehe, you mean, of course, s462...

And they're not exactly the same as thier s754 relatives, but they ARE exactly the same as thier Athlon XP cousins when socket A form.

[Uranium]

I wish I could get a sempron, but this motherboard is old

[moshpit]

So I guess recommending a X2 for it is out of the question?

[Uranium]

oh no! I'll certainly try to shove a 939 chip into this socket 462

[moshpit]

I'd say if you cut off about half of them, you'll be just about right

[Peter M]

You answered your own question. They're old and rare, and sought after by people whose old boards don't do Semprons.

You can still buy a Sempron and run it - at 4/5 of its intended speed (at 133 MHz bus), and it'll be misidentified as some odd AthlonXP speedgrade, but it'll very possibly work perfectly fine.

[Uranium]

that all depends on if the motherboard, of course. Not all bios's are built alike

[Peter M]

Speaking as a BIOS engineer now ... rest assured that there is little point in adding CPU support into the BIOS of a mainboard that can't run this CPU properly anyway.
