As you guys know, I know NOTHING about Athlons, so bear with me.

My friend has a SLOT type Athlon 900 CPU (Slot A?). At a glance it looks similar to a Pentium II Slot1 package.

This is the old Athlon, right? I know the new ones are a PGA type socket (I've seen them designated Socket A PGA? That's confusing).

Anyway, he's shopping for a new mobo, CPU & PSU but on the off chance he wants to try to use the old CPU for something, I assume they still make old slot A mobos?

The mobo he has in there now that toasted is a DFI AK70:

Clear up these designations for me. Is the old package a Slot A and the new one a Socket A PGA?


Thanks.

Yes sir,

The slot is the old configuration, while the new is the PGA.

From what I remember the ABIT KA7-100 was a great board, might want to search the forums for it. or one like it

I just checked ASUS: they no longer sell a Slot A board, tho you might find one in someones inventory.
Tho my mind tells me they must exist, I haven't seen anybody around here carry one for a year or two. There were too many problems with the CPU not sitting perfectly... intel too. Thus they gave up on the design.
I know somebody who may have an old/used/returned board (!) if your friend wants it... ?

Well I just did some quick checks and even Geeks and Directron doesn't have them anymore. Since the CPU is questionable anyway (a cap popped on the mobo so we don't know if the CPU is dead), I think his best bet is to buy a new CPU/mobo combo.

Thanks.

Also, be careful if he has a T-Bird. When they switched over to socket A with the T-Bird, they made some slot-A T-Birds so board makers could sell their remaining stock. Problem was, Via was asstastic as always, and slot-A T-Birds DO NOT work reliably on KX133 boards. Here's how to tell: Look at the printing on the top edge of the CPU cartridge. if the printing says:

AMD-K7900MPR52B, then it's the "classic" Athlon with 512k, off-die cache and will work fine with the KX133 chipset.

If it says:

AMD-A0900MPR24B, then it's a T-Bird and MUST be used on an AMD-750 chipset board.

At a glance it looks similar to a Pentium II Slot1 package.

It's damn close to SECC1, they can use the same heatsinks.

Also, Axion Tech has a couple of slot-A boards still in stock.

Hokay, I wound up keeping the CPU as trade for my services - taking a chance it's not damaged.

It's a K7900MNR53B - so is that a Classic or a T-Bird?

Okay, did a Google search and I suppose this is a Classic since both the MPR52B and the MNR53B are both considered Model 2 CPUs, while the MPR24B is considered a Model 4 CPU.

You're looking at the wrong string. The parts I bolded are the keys, if it says AMD-K7900 it's a classic, and AMD-A0900 is a T-Bird.

Take a look at this from ubid.com Might fit your needs and cheap too:

If you have never bought from UBID, I do recomend it. As with all "auction" type of site, look around before making the final bid. I never go over 50% of street price and have gotten some pretty darn good deals. Other times, I have seen people bid 10 to 20% over typical street price and just shake my mouse wishing I could email them and ask if they are AOL users!!!
