What's the overclocking like on these (either the original or the WinChip2)? Seen some old reviews say the 200 MHz ones hit around 225, but I'm looking to hit 233. I know there's a 225 and 240 version, but those seem to be much less common than the 200. Planning to compare a variety of S7 CPUs all at 233 and was wondering if this would be possible to include, would rather not have to compromise and have it run slower than the others.
