Does undervolting still kill Athlons?

[spleenharvester]

Hey,

I know ages back on the K8s people were killing them by undervolting, since the voltage difference between the CPU memory controller and Vdimm was too large, is mine safe?:

AMD Athlon II X4 630
2.8GHz (OC'ed to 3.12GHz)
1.425v (Undervolted to 1.275v)
CPUNB 1.175v (undervolted to 1.00v)

OCZ PC3-12800 SpecOPS (the stuff on superspecials ages back)
1.65v
8-8-8-24 @2T
1486MHz

Am I safe?

Cheers
