This is great for stability, but can be bad for more fragile chips because over volts can occur when the processor is under load. You'll probably be fine, but there is a much greater risk of you breaking something than someone with a 64nm chip.
Actually the LLC issues take place during idle not load.
It does seem that this board has resolved it though. I ran power monitoring both idle and load and the spikes present with the Asus boards capable of doing LLC do not seem to be present.
I personally cooked a highly overclocked E8400 on an Asus board through the direct use of LLC a few months ago (it fried while the system was idled and I was unlucky enough to see it happen while running a monitoring app).
My thoughts on LLC in general are changing after putting this board through its paces.
