Voltages

[danzhang16]

Hi there everyone, just wanted to ask about memory voltages, as I'm worried about rumours that memory voltages above 1.5v will kill sandybridge processors. I know that memory is recommended to be run at 1.5v in a sandybridge system, but I did a little googling and many people seemed to be very happy running such a system with the corsair XMS3 RAM, which is listed as running at 1.65V. So, should I lower the voltages manually in BIOS? or just slot the RAM in and let it run without any alteration? I have very little knowledge about overclocking RAM or changing voltages, so a little guidance (if needed) would be great. Also, will XMP force the ram to run at 1.65v? Thanks

With Sandybridge the lower the RAM voltage the better.

There are plenty of people running XMS3 at around 1.5V.

I would try lowering it in the BIOS.

As above - i've set up 3 machines (including my own using a MSI p67a-c45) with XMS3 memory and with each initial setup I set the voltage at 1.5v and have had no issues.

XMP will/usually force the memory to run at 1.65 - ideally set the timing and voltage manually.
