I'm kinda confused about this topic...
What really is the problem with running high voltage on the ram?
According to Intel Haswell datasheet, the maximum DDR3 voltage for the processor is 1.5V +0.05% = 1.575V. This seems very conservative since a lot of people out there are running XMP memory at 1.65V. I think we can consider 1.65V "safe". But what about pushing higher than 1.65V?
Apparently, the problem isn't the RAM itself, but the IMC. I read that the RAM voltage and the IMC (System agent, VCCIOA and VCCIOD on Haswell?) voltage should be kept within at least 0.6V range to avoid instability.
So in the end, if I can keep a reasonable offset on these imc related voltage (Sin's guide on Haswell OC recommends max 0.2 offset) I won't damage my cpu? Or does the voltage of the ram goes though the cpu or what? I thought the ram had its own vrm etc.
Thanks
