I have an Asus k55a-si50301p with an i5-3230M Processor, SAMSUNG 850 EVO 2.5" 250GB SATA III (MZ-75E250B/AM), CORSAIR Vengeance Performance 16GB (2 x 8G) 204-Pin (CMSX16GX3M2B1600C9) CAS latency stock 9-9-9-24 running at 1.35V. Intel 7260 802.11ac/Bluetooth 2.4/5Ghz wireless card soon to come.

Overall I am very impressed with my systems performance. It was pretty good stock but with the SSD and memory Upgrades I got a huge performance boost I see on Corsair's website and a few others that my memory supposedly supports 1.5v operation. I want to know how/is it safe to set the memory to 1.5v, do I have to change any timing or CAS latency settings or will that happen automatically? Also I have the Intel Extreme Tuning Utility but for some reason it doesent have a section for graphics to boost, only able to change the voltage of the turbo boost and I'm not comfortable messing with that as during gaming (Elder Scrolls Online, but most newer games) I run 95C to 105C Max TDP. I have everything I could find on the PC upgraded to high performance, SSD RAPID mode enabled, all services but microsoft and a few other selects are disabled. Any advice is appreciated, I'm mainly concerned with trying to do the last real upgrade in turning the memory to 1.5v and seeing what kind of gains I get out of that. Thanks!
 
According to your processor's spec sheet by Intel, your processor is capable of driving both DDR3 and DDR3L memory meaning it can run regular 1.5v and low voltage(hence the L after DDR3), 1.35v, rams. The reason to bump your ram voltage up isn't a good idea since:
a| if your ram(as well as the system) is running without issues then you shouldn't worry about it
b| using 1.35v as opposed to 1.5v is healthy for the IMC(integrated memory controller) as well as your mobile computing device's battery lifespan and consequently the heat output from your system. (power draw = heat dump).

You should NOT tune anything pertaining to overclock's as well as SPD's of Ram modules via software. It should all be done through the BIOS. I also reckon that the feature is devoid in your BIOS which leads me to suggest that the ram running at 1.35v is the optimal voltage(as well as latency's+frequency) that the unit deems fit. Your ram kit apparently has no ace up it's sleeve's when made to run at 1.5v since 1.35v gives you 9-9-9-24.

On a last note, what games are you playing on that unit? You're not supposed to going at those temps in that form factor as you risk damaging your components.
