i have to use the jumpers. the left pic is the jumper settings for a 533 dothan and the right is the 400fsb
533mhz set with pin mod ---> no post
533mhz set without pin mod -> no post
400mhz set with pin mod ---> post but recognizes it as a 1.6
400mhz set without pin mod->posts recognizing the chip as 1.6
the pins on the chip are perfect, no bent pins or anything. The msi s260/1012 uses the 915gm chipset BUT it uses ddr ram and not ddr2. It can handle a max speed of 400mhz ddr ram (up to 2 gigs of it though). Could that possibly pose a problem? I don't think it should, but who knows
