Not convinced....

Try cpu multi 19x and clocking with ram @ 6x multi and uncore at 12x. That will let you clock purely bclk and cpu core. When you find your max stable bclk you can try raising cpu multi and lowering bclk to go for more. These bloodrage boards like the 18 and 19 multi though.

Remember you can run 18x or 19x multi with cpu turbo on to get 21x under load and still retain the additional stability of using the lower multiplier (no idea why that works). Some cpus prefer 18, some prefer 19.

Be prepared to add vtt as you increase cpu core clock/volts, even if lowering bclk or memory speed.
