Serious problem with my Dual Channel RAMs

[kosmiq]

Are you sure the memory thingie is not adjusted by % in the bios?
I took the time to look into a review and it says;

Basic overclocking-related options are also found in the Advanced Chipset Features page:

* CPU External Frequency can change from 100 to 300MHz stepping 1MHz;
* CPU Frequency Multiple – this parameter changes somewhat irregularly. You can set it to 13.0x, 13.5x, 14.0x, 6.5x, 7.0x/15.0x, 7.5x, 8.0x/16.0x, 8.5x/16.5x, 9.0x/17.0x, and from 9.5x to 12.5x stepping 0.5;
* Memory Frequency is set up in percent of the FSB clock rate: 50%, 60%, 66%, 75%, 80%, 83%, 100%, 120%, 125%, 133%, 150%, 166%, 200%;
* CPU Vcore changes from 1.5V to 1.75V stepping 0.025V;
* AGP Frequency can be given the following values: 50MHz, from 66 to 87MHz stepping 1MHz, 90, 93, 95, 97, 100MHz.
* DDR Reference Voltage – 2.6V, 2.7V, 2.8V. That’s rather a scanty choice
* AGP VDDQ Voltage – 1.5V, 1.6V, 1.7V. We can change the voltage on the AGP slot of the mainboard.

Thats from X-bit Labs.

So by reading that I also see that you are to go to the Advanced Chipset settings tab and change what you need...
