yes u are correct the BLIZZPPC can not take some double sided simms,but i have found a way around this by getting a nail clipper & cutting the legs just above the soldering on the BLIZZPPC CPU simms side & useing a small file to get to the inner legs...
my BLIZZPPC now can take any simm module...
both my simms are fitted with akasa heatsink..
overclocked BLIZZPPC..
also disabled regulater so processors can be powered directly from powersupply 3.3v... bvision also powered directly...
useing antec truecontroll powersupply..
DO NOT TRY & COPY MY MOD.. VERY DANGEROUS..
