Need some suggestions on overclock!

[MovingTarget]

Okay, I have overclocked my computer for a while now and it's rock solid stable, but I think I can squeeze more out of her because I have some crap ram installed. I got a couple of questions.

Here is my system specs
Clawhammer core 3200+ @ 2.3ghz
2 sticks of Corsair XMS at 2-3-3-7 (which allows only a 10 mghz overclock)
DFI UT lanparty socket 754 mobo
LDT x4

As of right now, I have been running this setup for a year and it's been rock solid. I think I would benefit if I bought some new ram because it seems 2.3 seems to be the plateau i can't get over. I would like to run my ram synchroneous. SInce the clawhammer cores are only single memory channel, would u guys think I'd be better off getting a one gig stick of some ballistix or ocz memory? I saw some PC4000 Ballistix that I am currently looking at that some people said runs pretty good at 2-2-2 timings. What do you guys think?

Here is a cpuz pic of what I got going on at this point of time.

I have PC3200 Ballistix and with the help of a DDR Booster (3.2V) I can get at least 216MHz at 2-2-2. I don't know the upper limit as I just discovered the effects of "Aggressive Timing:" in the bios. It ought to be renamed "Crap Overclocks:"
