Well oc'd my 6320 to 2800 and orthos had a fit, so back down to 2100 it went. which is comfortable.
Maybe i'm doing something wrong or my memory settings are out, but followed the guide.
Still it's stable at 2100 which is good enough for me as it's my first ever attempt at overclocking.
Anyway, this is what it's looking like now.

And a big thanks to Clunk for showing it's easy to overclock - and easy to bugger your pc if you do it wrong
