I just put together a new 'puter that won't boot in 133 front side bus mode. Soyo's tech determined that the CPU was bad. If the 2BA1 BIOS was set to 133 fsb and booted while holding down the <INSERT>key, it still would go black immediately after one beep. When I pulled the heatsink off the CPU, I could see that it had only contacted about half of the Arctic Silver II. Temps were around 49 degrees Celsius idling and 59 under max load.
The machine ran fine at 100 fsb,. However, every time I booted up at 133 there'd be one beep followed by a black screen, while fans continued to run. After I cleared the CMOS, everything would be fine again, only at 100 speed. This happened even if I booted up cold. I think it's a coincidence that the heatsink was making only 50% contact, as it should still have been able to boot at 133 fsb. My reasoning is that even if it got hot eventually, that should not have affected it when it's cold.
Your opinion, please.
By the way, someone has suggested that the heatsink's clip was on backwards, which I must agree was most probably the cause of the relatively high temps, but I haven't retested yet. I am still betting that the problem with the 133 fsb is due to the CPU and not the heatsink mounting. What do you think?
[EDIT: it works now after remounting the heatsink clip correctly. Temp around 35 degrees until I bumped up the speed and set aggressive memory timings, now at 36 degrees. But my house is under 22 degrees Celsius, so it's cold in here. Thanks for all the help.]
