What happens if you run the CPU at stock speed?

My 2.4B has run at 61C 24x7 since I got it... I've never experienced an error yet... Personally, I don't get all freaked out about CPU temperature...

What is your PCI bus running at? Can you lock it at 33MHz?

Also, in my experience, Prime95 will respond much better to faster memory than to a higher CPU FSB...

In your current setup, you are increasing the work the CPU can do, but you are not bumping the memory up in a equal fashion... DDR memory is already short on bandwidth to begin with...

With dual channel DDR it will be a different story (Supposedly the Granite Bay chipset-based motherboards will be released within the next month!) but for any single channel setup memory performance is critical...

Example: I recently upgraded from a 2GHz P4 with a 100MHz FSB to a 2.4GHz P4 with a 133MHz FSB... My chipset (845G) will run asynchronously, so the memory in both cases is 133MHz... The upgrade, while faster, was not as fast as I expected, because the memory bandwidth in both cases stayed the same... I suspect the bandwidth was close to being saturated at 2GHz and at 2.4GHz it is totally saturated...

Solutions?

I could pop in a DDR333 memory stick since the 845G unofficially supports DDR333...

Dual channel DDR...

RDRAM...

Increase the FSB of the memory as much as possible...

I'm waiting for the dual channel DDR...
