I have a matched pair of PQI PC4000 modules. They use the excellent Samsung TCCD chips. Works great single channel up to and beyond 500MHz (either of the two modules)... but as soon as I add the second, I get a "system failed memory test" beep and the system won't post. I've even tried underclocking the memory and using the most relaxed timings. It just doesn't work. My older Kingston HyperX modules work fine dual-channel (but don't clock nearly as high).
As an interesting side note... the Kingston memory I have is registered, and seems to work fine on this board.
Anybody out there using memory with TCCD chips successfully dual-channel?
