We managed to overclock the Soltek K890Pro-939 to a maximum stable speed of 280 MHz on the HT bus, with a memory divider of 6:5 (166 MHz), HT multiplier of 4x, and CPU multiplier of 8x. These settings resulted in a total CPU clock of 2240 MHz, memory clock of ~233 MHz, and HT bus clock of 1120 MHz. The SATA1/2 ports appear to be locked, as we did not experience any problems with data integrity.
