Oh yeah, I did do that. i'm at 1.32v @4.5Ghz under WCG load now; not sure if this is 100% stable yet. My temps are very good, 51 - 57c right now. I only tried quickly but couldn't post at 4.7Ghz or 5.0Ghz, didn't try 46 multiplier. I'm sure with tweaking I could get the higher multipliers to work but it seems like 4.5Ghz is a sweet spot for this chip.
