Same here. I used to use ASUS quite a bit, but lately been using others. ASUS seems to lack the overclocking features I need. On the 815 boards (xUSL2), they lack a 1/4 PCI divider below 133 FSB, and have problems requiring a special (hacked) BIOS above 140 MHz FSB. They also have limited voltage tweaks (no undervolt, max 1.6 Vcore). For the 815, the ABIT ST6 and Gigabyte GA6OXET (very nice board) are better boards. I recently went to a P4/i845 setup. I looked at the ASUS P4B266, but it lacks a 3:4 mem ratio @ 133 FSB and above. This was an important feature for me. I went for the EPOX 4BDA2+ since it did have this feature. The EPOX works great! I'm running 150 FSB, 2.4GHz, 400 MHZ DDR.
