I think something else is going on.
Probably with your OC, or possibly the motherboard.
1. Check to see if there is a bios update that might address stability issues. Do not update the bios without a good reason. A failed update can brick your motherboard.
2. How is your cooling?
3. I see no reason why a OC failure should damage a ssd.
But... the OCZ ssd's used to have a higher return rate:http://www.behardware.com/articles/881-7/components-returns-rates-7.html
Regardless, you should be able to rma the failed ssd
4. Is your psu good? Perhaps that could be failing.
5. Motherboard easy oc capabilities are often too aggressive. Try just raising the multiplier gradually, and leave everything else on auto. 4.4 may be too high for your chip.
6. 100 is the default BCLK, increasing that changes lots of interrelated settings. I would leave it at 100, and forgo the added 2% or so that increasing it would bring.
7. Lastly, how good do you need to be? Do you really need more than 4.0?
