Hi Ozlay. How's that M2N32 doing? Hope it's still treating you well. What a gr8 board.
Your question is basically the same one I just asked recently. Sandman gave a good start of an answer, but I'm not yet in a position to help since I don't fully understand all the interactions myself.
The conventional wisdom here and on the Vishera thread seems to suggest that there isn't much benefit in increasing the speed of the NB interface with AMDs new FX processor line. But if even if you chose to do it, you would need to compensate by increasing the CPU-NB voltage. And without supplemental cooling on the 990FX, this is not a good idea to pursue.
With regard to you actual question, I can offer the following. With this new Samsung DRAM I'm using, there are many posts suggesting these parts will run fine at 2400MHz. What they don't tell you is what the rest of the system is doing. If I have to back off my 4.8GHz CPU speed, I'm not willing to make that tradeoff without good reason. So, when I set Memory speed to 2133, I too saw a failure getting the system to even POST. I didn't want to pursue this path further unless and until I understood what needed to be done in BIOS. Perhaps we will all get some enlightenment.
