Yes, my 2.4B ran at full speed. Funny story, I bought the board, RAM, and CPU used 2 years ago for $150. The RAM was kinda crappy and overheated, it was sold by the old OCZ company that was bought out by another company last year. I put a fan on top of my video card, pointing toward the RAM, to keep it cool in the summer. OCZ had a lot of problems back then!
So I had the Intel i850E board with a 2.4B (533 bus) and PC1066 running fine. One time I reset the BIOS and was greeted with the "unapproved RAM" comment, but every boot after that was fine (I guess they only warn you once). Sandra reported everything was great. I believe I used that platform as a bassis for comparison in my PC4000 review (PC1066/i850E vs PC4000/i875 at Sysopt).
