4930k and ram question

[Zet]

i've google it and it seems people have very different opinions when it comes to a 4930k

 

some say ram should never be above 1.5V 

some say ram is more than fine at 1.65V

When XMP is enabled, the RAM may use 1.65V. It's safe to do so with XMP, not sure about non-XMP sticks though.

well it's more about not sure what it's called the memory voltage controller or smt ( i believe it's on the mobo ) and people say it will fry it eventually

@MageTank is the boos around these parts when it comes to RAM, but I doubt that 1.65V kills DDR3 modules. Unless the board isn't meant to handle 1.65V (say an OEM or cheaper board), it shouldn't cause any damage to the IMC, chipset, or RAM slots.

vDIMM is supplied from the board, directly to the ram. It does not come into contact with your IMC. It will not fry it, or degrade it over time. The two voltages you must worry about in regards to your IMC, is VCCIO (the voltage going into and out of the IMC) and VCCSA (your IMC and PCIE subdomain voltage). For that specific series of CPU's, try to avoid going above 1.050 for each value, as you shouldn't need to in order to make DDR3 stable.

 

For vDIMM, you could run 1.7v 24/7 and still be fine.
