I have had the 9CJS for about 2 weeks now and it is a huge disappointment so far.
I am using 1GB (2X512) of Corsair high speed, low drag, teflon coated memory that I paid dearly for and the best I can do on the fsb is 230 and that is not very stable. I leave it at 225.
I have overclocked several Abit and a couple of Asus and even a couple of MSI boards with success but this one has me beat. Maybe it is the luck of the draw on the CPU, a 2.6C that does not take well to overclocking but I do not think so because even the Corsair memory has to be left at default settings for anything over 221Mhz.
Great board at default settings and VERY mild overclocking but only get it if you like all the dog and pony show accessories.
By the way, if anybody has any ideas or advice, please feel free to jump in.
