I am going for 4 ghz and I think I am there. I uninstalled smp folding & reinstalled and it seems to be working now. I only get 6000 +-ppd though. I am still playing with voltages trying to get temps down. I have a megahalem to install to help me also. I had to set the cpu voltage to 1.3 to get there so as you can imagine it gets a little warm.That sucks....what kind of OC you got going? There is a good ~9K ppd in that chip. Small FFTs test mostly the cpu....you really stress the ram yet? Try memtest and large FFTs? Your setup is close to mine, and I got 3.4GHZ first try no probs, and folds no prob too.
