its still a "disabled-half-cache of sandie" anyway
need high vcore to stable @ 2.8GHz above

I dont think there is a "best way" of burning-in a cpu. Everyone got their own resipi to burn-in tho.

What i knew is, you try to stress your cpu at certain clock speed with certain vcore for long period of time. After the stress/burn-in, try to prime and see weather its stable o not. If not, increase the vcore by little (until the system is stable), then find out the max stable clock at that vcore, and stress/burn-in again for long period.

Continue the process until you felt the vcore is high enough for your proc. Then, switch back to the lower vcore. If you lucky enough, you "might" stable up a few MHz with the same vcore you set last time.
