If you want to try this one again, then try up to 1.7v vcore, and disable 2 cores because you can hit higher CPU-NB frequency with 2 cores on Zosma/Thuban Also, not sure why it says single channel, but if your reapers are rated between 1.7-1.9v, don't be afraid to give them 1.9-1.95v. That's about all the CPU will take. If you have any more questions on tweaking times and such I'm sure the guys at OCF will take care of you

It's actually running at 1.7v vcore ! For some reason cpuz is reporting low,and I dont know why but I can't get as good a clock on the memory when running 2cores :shrug: I can't remember what voltage I was putting through the ram but no doubt it was a fair amount , thanks for your tips.
