Check the BIOS to see if you can run the ram and cpu asynchronously. Need the cpu at 133/533 quad pumped and the ram at 800mhz. Otherwise you need to get PC1066 rdram.

Such is my memory anyways, haven't built an rdram system since the VERY first PC1066 came out, every one since then I've stuck with dual DDR.

You removed the 45ns memory and jsut have the 40ns memory in there now, correct?

Have the latest bios? Version P25 adds support for latest processors and fixes processors with wrong speed reported.

Your board DOES support PC1066, but Intel simply didn't APPROVE the stuff. I had the same board, it displayed a message saying PC1066 was not approved, I clicked the key to pass the message and it was never displayed again.

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).
