My Thoroughbred is registering as a Duron??

[GrdLock2002]

I just got my Athlon XP 2100 in today. I have an Asus A7M266 mobo, which even with the latest BIOS is only supposed to support up to the 2100 Palamino, not the Tbred, but I couldn't find a Palamino so I thought I'd give the Tbred a try.

After popping it in, I booted up with soft jumpers on, and could only get the CPU to run at 1.4Ghz. So I tried getting off soft jumpers and using the dip switches on the mobo, and the only way I could get it to boot up was by running it at 1.8Ghz (the 2100 is 1.73Ghz, right?) so a little overclocked, but oh well, hopefully that'll be stable.

Then when I got into Windows, I looked at my System Properties, and for my processor it says I have a 1.92Ghz AMD Duron.

Why is it telling me I have a Duron? Is it just something about the BIOS not knowing what the Tbred is? Will this hurt my performance at all with it thinking it's a Duron as opposed to an Athlon XP?

2100+ is 1.733, correct.

Download wCPUid (search on Google), and run it to see what that program tells you, including the amount of L2 cache. If you have SiSoft Sandra (free, search on Google) that works too.

Hmm, got wCPUid...

Under processor, it says AMD Athlon XP, but then under Name String it says AMD Duron. It's running at a 200Mhz system bus, not 266 like it should, right? And 100Mhz system clock, 19.0 multiplier, 256K L2 cache.

It's calling it a Duron(most likely), because the BIOS doesn't recognize the CPU.

as long as the system works fine without any errors, you should befine. The latest BIOS for the mobo just doesn't have the ID string for the T-bred so it just goes with whatever it thinks the CPU is. This is just like when you upgrade older Slot-1 BX boards with a Slot-T or Powerleap Tualatin adapters. Mobo's come up with weird names like Pentium-Pro, Celeron, etc...But they usually work perfectly.

100 * 19 isn't quite 133 * 13, which is quite weird. Your board has the AMD760 chipset (I think) so it should work at the higher 133 bus. If so, you could probably manually switch the bus to 133 and make the multiplier 13 (or raise it a bit to 13.5 or 14 if you want to overclock).
