Finally got my RAM to run a 2933, it's like magic. Team Group Vulcan's for those who are interested. Now to get the Core stable at 3.8Ghz, it's taking a lot of volts to just load Windows, so possible that I lost the lottery with this Chip (1.35v to get to desktop).
At that voltage I'd give up at this stage.
1.2875v bios, 1.224v under load for me for 3800. I think I have an average chip.
I think these chips have a cliff where loads more voltage is needed. For example need 1.4v bios to get 3900 and I don't even think that is 100% stable. No point.
