Ok, you RAM timmings are fine, you don't need to change that, set them to default state (I think it's 2-3-3-6), make sure the command rate is set to 1T, I'm sure that this CPU will work to 2.2 GHz so simply increase the HTT to 220 (the multiplier is 10X, right?), lower the HT multiplier to 4X (220*4=880, it shouldn't go past 1000), you RAM should work at 440 MHz if mine did, if not lower it to 333 MHz. I'm not familiar with dual core overclock successions but I think that it can handle 200 MHz OC.
