Hi I am wanting to upgrade to 8gb of RAM, to be on the safe side is a Corsair dual channel XMP, 1.35V set suitable for the Lynnfield i5 750 (first generation i5) with a MSI GD65? The max voltage is 1.65v so I'm sure 1.35v will just be fine (if not better). Although I want be safe than sorry. Would I need to set the voltages manually if they have been set at 1.65v in the bios?
The rule is it mustn't be more than 0.5v away from the VTT voltage or it could damage your CPU's memory controller. Can't remember what the default voltage is but with my overclock reads 1.195v in MSI's Control Center I'm pretty sure it's not that far away from default so the lowest voltage I could set my ram to would be 0.695v. Will you be removing your current ram?
1.35V is fine with Lynnfield. I would not mix 1.35V with 1.65V, but you can generally run 1.35@1.65V. Unless it has XMP to enable 1.35V you will need to set it manually otherwise it will default to 1.5V according to JEDEC DDR3 spec.
Yeah I was considering selling my 4gb 1600Mhz Corsair XMS3 as 12GB would be overkill/not required. This is the RAM I was considering, however if it is not suitable I will just go for a 1.65v XMS3 or blue vengeance @ 1.5v. Thanks for your input so far, +rep.
