I have an MSI KM2M.
Is there a reason it wouldn't work with a 2600+ Athlon MP? It supports 2600 XP (both 266 fsb).
Both are Thoroughbred cores.
I would expect it to work, does it work with an Athlon XP 2600+ or any Athlon XP CPU? If not could be an issue with the motherboard, how do you know the Athlon MP 2600+ works?

The board currently has an 1800+. I don't have a 2600 on hand, thats why I ask. The MP model is A LOT cheaper than the XP model.
MSI's site doesn't mention anything about the MP models but, I would think they're the same beside name (and iirc the MP has multi processor support?).
Further forum digging confirms my thoughts. Guess we'll see what happens.

MP just means multi processor as in if you had a board that supports dual socket you could run two of the MP processors but aside from having multi processor support enabled itll work exactly like the XP 2600 does in a single CPU board, IIRC MP processors usually have their multiplier unlocked too so it might be worth checking if your does as itll let you bump its speed a little.
Mobile and low power Athlons will have Mobile or SFF in their names but again they will also work exactly like their XP brothers but use less voltage so itll be up to your motherboard if itll have the right volrages for them.

Yes, they have multi processor support and they report this as the MP bit via CPUID. If you get the MP 2600+ I wonder, will it report MP, please let me know.
I also have an AMD Athlon MP 2400+ (Thoroughbred) and when I got it I needed to update the BIOS, see Re: Can I safely run my TYAN S2466 (Tiger MPX) with one Thoroughbred and one Palomino CPU?, so it would be wise to make sure you have the latest BIOS.
Where can I get the cheap AMD Athlon MP 2600+ (Thoroughbred) s? My 2400+ would like a friend and I suspect a 2600+ + 2400+ will work.

The reported names are whatever the BIOS sets, on my system CPU-0 and CPU-1 are identical, but report different names, further my Athlon MP 2400+ (Thoroughbred) reported name changed after I updated the BIOS.

Names in listings, CPU ID sticker, I have enough different types of 462 Athlons and they are all very clearly identified from each other. ...obviously the BIOS will report whatever its been programmed to report regardless of how incorrect that may be.

So what is your point? Initially you specified names which is ambiguous and could be either the name set/reported by the BIOS or the information on the physical package, given this I felt I needed to point out that the names set/reported by the BIOS are not reliable.

Ebay. I won't say cheap but, cheaper than a 266fsb 2600 XP.

Thank you, I was wondering is there was some other source. I look on eBay from time-to-time and thus far nothing has turned up at a price I wish to pay, my Athlon MP 2400+ (Thoroughbred) came from eBay and was GBP 9.95 with free postage!

right, I don't see any further reason to discuss this with you
Got the CPU. Appears to work just fine. Board identifies it as an XP. AIDA64 does as well.

I am happy to hear it works and I guess the BIOS only expects XP CPUs so reports XP, but I would have thought AIDA64 would report MP if the MP bit is set in CPUID 80000001 EDX, maybe it's not set. I wonder what my SIV utility would report.
If MP is not reported I will be half tempted to see what happens with an XP + MP in my system.
