Experiment gone wrong?

As an experiment, I bought a 3.0c the other day and put it in my Abit TH7II Mobo (i850 chipset) to see what was up. Well... the fastest I can get it to run stable is ~160fsb. The weird thing is that the whole computer just chugs and chugs and chugs. I was just wondering if anybody had any ideas as to why it would chug so bad? with a 1.6@2.4 3dmark03 was hitting 6300 easy. With the 3.0c@2.4, it was barely hitting 4500. Any opinions?

Here's a little update. I flashed my mobo's bios and now the 3.0C@2.4 is running exactly on par with the 1.6a@2.4. So now I'll just leave the cpu where it's at until I have enough $$ to get an ASUS P4C800-Deluxe and 1Gb of 4200DDR. It look like the only factor holding me back from being able to clock this chip at stock is the PC800 ram. For some reason the mobo won't post if I fix the ram at 400mhz. It will only post with the ram timing set to auto, in which case the ram is running at 480mhz. With the 1.6a@2.4 the ram was running @450mhz. If only I could gte the board to post with a fixed ram timing... oh well. I'm content until I can get the mobo and ram )
