Epox 4BDA2+ - 1.8A - 2.4GHz

And I'm happy with that little OC. As you might guess from my handle, I don't have much experience at this OCing effort but I couldn't resist trying one of these P4 Northwoods at 133MHz bus speed. First mobo was a Gigabyte GA-8SRX SIS based board and there must surely have been something wrong with that board - totally erratic behavior and no OC at all. Sent it back and ordered the Epox 4BDA2+.

From the getgo (excluding one little memory setting error - my fault) the L145A797 1.8A Northwood came to life on this motherboard. Settings are 133fsb, 133mem, spd auto for Crucial 2X 256MB PC2100, AGP and PCI buses locked at spec, vcore at 1.55v, mem at 2.6v, agp at default. Using stock Intel HSF with ASII compound and currently reading 39 degrees C from the processor. CPU temperature has been as high as 47 degrees during heaviest loading so far but should calm down as the ASII finds its equilibrium. Case is HX-08 with top 80mm blowhole, Enermax 350watt, Silencer front intake and top blowhole fans. Nice and quiet. I like it!

Bought the mobo from Outpost, best delivered price I saw.

Wow, Congrats!

Given my usual amount of courage for these things, I have backed it down to defaults after convincing myself I COULD run at 2.4GHz if I want. I also ran it for awhile at 2.02GHz with memory at 149/298 and got my best memory benchmarks there. The crazy thing about these P4 setups is that I am actually getting BETTER performance at 1.8GHz than I was at 2.4GHz mostly because of improved memory performance. What is up with that?

Why would good PC2100 perform better at 1.8 than at 2.4 given the memory speed was identical at 133/266? Makes no sense to me but that is what I'm seeing.
