ASRock x58 Extreme and G.Skill DDR3 1600

You should be able to change it manually, if possible. If not, try overclocking the cpu by about 33% to start. That is what premium ram is made for.

As I stated, if anyone would have step by step instructions on how to fix this issue, that would be great.. Seems to be a wide spread problem with this motherboard, and someone has to have solved this issue!  

To overclock the Core i7 920 at our disposal, an engineering sample with QPI multiplier and clock speed of the memory block to up, we originally done by decreasing the frequency multiplier CPU to the value of 12x, so you can have ample room for intervention in terms of frequency of buses. We also operated on the QPI bus multiplier, ensuring not go beyond the frequency of 3.200 MHz, corresponding to 6.4 GT / s, which is specification for the Core i7 965 Extreme. After these tests we obtained a stable operation at a frequency of 190 MHz of bclk, which coupled with 12x frequency multiplier allows to obtain as a result of a frequency CPU clock of 2280 MHz In these tests we have also left the divisor of DDR the default for DDR3-1066   , equal to 8, getting as resulting frequency of working memory DDR3 1520 MHz effective, the Turbo Mode technology has been disabled while the clock was Unicore equal to 3040 MHz, through the use of the 16x multiplier.
