I've got an E0 stepping Q9550. Only have it OC'd now to 3.4 GHz (8.5x400, 4-4-4-12), but it's under-volted to 1.120v in CPU-Z (1.15v in bios), 14.5 hours Prime Blend stable at that speed.
I haven't tried pushing it anymore, but was just curious if that sounds like it's a good one from that info alone.
This is running on a Gigabyte UD3P motherboard.
LLC is on, VTT is at 1.1 (lower than normal right?), not sure what else to list.
Edit: Just to add, I tried running it at 1.1v in bios (I think like 1.06X in CPU-Z) @ 3.4 GHz, boots into windows fine, but Prime Blend crashes a little ways in, maybe within 5-10 minutes. When I say crashes, I mean Prime doesn't fail, but it's a windows error that Prime has to be shut down, etc. This is with VTT still at 1.1. In case that sheds any further light onto my prospects. However, it did pass 5x runs of IntelBurnTest.
