I am having problems isolating bclock from memory


First: My motherboard is an Asus P7H55-M PRO w/ i3 CPU and updated BIOS

Second: I have it oclocked to 4.19GHz (easily) but I can not find how to seperate my bclock from the memory.

So my FSB: DRAM is at 4:12 w/ 571.4MHz and I was wondering if I can adjust that ratio to try and get a little more performance out of the RAM. I've tried everything that I can, with the knowledge that I have, to try and figure it out but I'm at a stall. I guess another option is to call Asus support and see if someone there can provide more insight, but I thought I would ask here first hoping someone has experience with this motherboard.

So am I on the right path to try and maximize my RAM or should I be doing something different?

Any tips and suggestions would be greatly appreciated and I thank all inquires in advance.

With the current BCLK of 190MHz and a DRAM multiplier of 6x (190 x 6 = 1140MHz), change the DRAM Frequency setting from 1140MHz to 1520MHz (8x DRAM multiplier; 2:8 FSB : DRAM ratio).

Isolate the bclock from the memory
The fastest rated speed for memory on P55 with an i5 750 (for example) is DDR3-1333, which is a clock speed of 667MHz (dual data rate “DDR” doubles the bandwidth to 1333-like speed). Just like the CPU, the memory receives its clock from the bclock via a multiplier, in this case x5 (133×5=667). This is most often expressed in the BIOS as “2:10″. If you were to overclock the bclock to 200MHz as described before, your memory would be running at 1000MHz (DDR3-2000), and beyond the specs of all but the most extreme memory. To isolate the memory from the bclock, lower the memory multiplier to the lowest setting available, most likely 2:6. If you were to reach your goal of 200MHz bclcok frequency, your memory would only be at 600MHz (DDR3-1200) and well within the capability of all but the worst DDR3 on the market.
