no, the chipset is 845, not 915. if it was 915, u could just do a pin mod to up the fsb from 400 to 533 mhz giving u an easy 33% oc without any voltage bump.
highest banias is 1.7 and highest 400mhz dothan is 2.1 (model #s 715 - 765 = 1.5 - 2.1ghz)
i see 2.1ghz 765 going for $120, 2ghz 755 going for $90 and 1.8ghz 745 for a bit less on ebay.
but at those prices, u might as well wait for a $350 laptop deal to come around and hop on it. the tech will be much faster, even if it were going up against a 2.1ghz dothan pin modded to 2.8ghz.
