really sorry to hear about this gmcg, and yes, i know there are issues with the support, interestingly and contrary to anything else, the china support is awesome while the us support is... not that good ive already contacted the tech support department and ill work with them to improve the support.

Its weird that the pciE speed did not reset after you reset the CMOS... it should reset the pciE speed even when oc recovery kicks in, so... this is definately weird...
Ill see if i can give it a try...

Gendo, the first 2 slots work very well with default clock dll settings while slot3 and 4 need clock dll adjustments to reach high clocks (2ghz)
thats what i found, but thats using 1gb micron sticks... its weird that you cant get the mem to clock well even at those low speeds...
try the clock dll settings in the memory timing section, usually going lower gives you better results. depending on the clockspeed -1 to -4 worked fine for me, the higher the clocks, the lower the setting.
