From what I've seen the problem is voltage.
I've got two sticks that will do 172 together. Im currently running one by itself at 195. Any more and my PCI can't take it.
Another stick does 187 in my system with a 350 sparkle (Has 3.45ish on 3.33) and wont even do 175 on my 300 L&C (dips to around 3.15-3.2 on 3.33 when overclocking)
It's just a theory at the moment But I bet if you get a power supply with ASSLOADS of 3.3, you will have no problem overclocking 2+ sticks of ram. This assumes ram voltage comes from 3.3 (I guessed that much because that is where the biggest difference between the two supplies was).
It seems logical to me that if power supply is a problem for one stick... it's even more of a problem for two. But once I've tested this, we will see.
