xtreem uccc 0603 batch pc4000 user here
no luck going beyond 265 1T.. even 265 is only 32m sPi stable..
oh well, as long it works at rated speed n beyond, im fine with it
probably my mem controller very weak.. n my mobo lack DS n DDS option
sigh =__=

p/s: those at XS have later batch n ultra-d mobo..

tweaking a UCCC is easier than infineon's counterpart...
however, dont expect UCCC to go as high as TCCD..
