Nice clocks aslanwas, impressive getting 600 MHz CAS4 32M stable.

I don't think that's going to happen at 2.3 - 2.4v though.

I have a kit that have been run at 2.5 - 2.78v on air (with fans of course) for at least 15 hours, and I have since stress tested them and they are as good as ever, no degradation at all. Some kits are just more resilient though.
