A64 MEM HTT Noob

I have had an A64 for a while, but until now I had the K8v SE Deluxe with out AGP/PCI locks. I decided to sell that combo on ebay and now I have a 3200+(90nm) with the Neo4 Ultra. My question is this I have no idea on the right way to OC this thing I have got it running at 2.2 which is the speed my old Newcastle was at but I don't have a listing as to what my bus speed is at. I have BH-5 memory so I know I have some room but I want to see where I can take this thing. Here are some shots of what I am at now so I would like to know where I need to go from here.

No one can help me out on this.
