bwi's 1700 is probably a t-bred chip. They run at lower voltages and the 'B' type ones overclock well. Also the temp of 38c he gives is most likely from the sensor under the socket, his on die is probably mid to high 40s.
My 1700 tbred B is also running at 2.18, I limited by a kt333 board and can't go any higher with the multiplier. My mushkin ram is PC2700 cl222-1t, and although it could go higher, the board is unstable at anything over 171 fsb, so I'm stuck at 2.18ghz.
That's fine by me for now, when I get an nForce2 motherboard and some good pc3200 or pc4000 ram we'll see what this chip can top out at. Best $65 bucks I ever spent. 710mhz overclock first try, no tweaking, bumped the voltage .025v.
That's why I voted AMD. (Also because the first computer I owned that wasn't given to me was a k6-2 550, and I wish I still had it, great chip)
Dual Barton Mobile 1.8ghz
Venice 3000+ @ 2.6ghz
lots of BP6s and two VP6s all apart currently
