scifiman Posted December 16, 2004 Share Posted December 16, 2004 As seen in the title, I have a foxconn 755a01 motherboard (now known as k8s755a) It is an athlon64 motherboard with many great features. I have a single stick of 512Mb Corsair VS512MB400 (CAS 2.5) with an athlon64 2800+ and it runs like a champ at DDR400. I recently got another stick of the exact same stuff - Corsair VS512MB400 and now, with both sticks in, it only reaches DDR333. I've tried the ram in all combinations in the 3 dimm sockets. Each stick by itself run at DDR400 just fine, but not both together. According to Foxconn's (foxconnchannel.com) motherboard manual and from there tech support, the only thing that will prevent two sticks of ram from not running at 400 is if both sticks are configured as x8 double rank. I'm not sure what exactly that means but i think thats talking about the layout of the chips on the pcb. The ram does have 16 chips but is it x16 single or x8 double? If it is x8 double then i guess i'll live with ddr333, hey i still have a gig of it right! :biggrin: but if there is anyway to make this run faster, i'll take any suggestions. There aren't many bios options to tweak, so its either going to be the ram or the motherboard thats the problem and the mb has the latest bios on it.
