Gigabyte motherboard RAM settings

I was looking for some info regarding my AMD motherboard (Gigabyte GA-890FXA-UD5 rev2.1(Bios F6)) and found this useful info

You are better off not trying to run your RAM above 1333 Mhz. when using an AM3 Phenom or Athlon CPU.
If you do so, you run the risk of system instability and even damaging the Memory Controller on the CPU. If, like me, you have invested in 1600 Mhz RAM, you will actually benefit from running your RAM at 1333 Mhz and tightening the timings. You also gain better performance by slightly overclocking your CPU. If, however, you do overclock your CPU, it is stongly recommended that you purchase a good quality 3rd party CPU heatsink to aid CPU cooling and also remember that officially, neither Gigabyte or AMD support overclocking of their products.
If you wish to run RAM above 1333 Mhz. and your RAM is rated at a higher speed, you are not overclocking your system. However, AMD recommend that you only use memory that appears on the QVL as this has been tested for compatability at higher speeds. If you are unsure about the compatability of the RAM you have bought the safest option is to run it at 1333 Mhz to avoid damaging the Memory Controller. If you are looking to buy RAM that is faster than 1333 Mhz. and it doesn't appear on the QVL be prepared to downclock the modules to gain system stability. There are no guarantees that the RAM will run as stated and you could possibly damage the CPU's Memory Controller.

THIS IS VERY IMPORTANT:If you do manage to get your RAM running over 1333 Mhz., your system can appear to be fine and might even pass Memtest and other benchmarking utilities successfully. However, AMD have discovered that, in certain scenarios, the system may fall over after a period of use, depending on system usage and if you are stressing the CPU. This normally indicates a problem with the Memory Controller and you may need to replace your CPU if this happens.

What is the DRAM EOCP?

It stands for Easy Over Clock Profile and the BIOS can read the information on the RAM (if it is present) and automatically set the system to run at this.

As I said previously, with the Athlon processor AMD recommend running RAM at 1333MHz or slower. You will probably have to set this in BIOS and you do this under the MIT section.

Change Set Memory Clock to Manual
Next set the Memory Clock to x6.66 (1333 MHz)
Change System Voltage Control to Manual
Check the Voltage for your RAM Modules (printed on the label or on the packaging) then set the correct voltage under the DRAM Voltage Control. If the Voltage for your RAM is over 1.50V you will notice a warning message that flashes in red you can ignore this. So if, for example your RAM is rated at 1.7V you will need to set this here and it is safe to do so even with the warning message
