Sorry for not replaying sooner...I have take some time off...from everything

Well, I got another pair of TG memory with UCCC chips and this is better, but as
far as overclocking it is almost the same ...the fun end around 260Mhz...but this
pair is at least Prime stable at 255Mhz (with 406 bios default timings which are
pretty tight...at least compared to the previous timings). But I also upped vcore
a bit ...so maybe this is the solution...that the memory controller needs more
juice for 2x1GB sticks.

In the week ahead I will also try Prime with lower vcore and also 257/259 Mhz
in order to determine where the Prime stable wall is.
