Current 8gb stick I have installed says 1.5V specs, but the system info says, that it's running at 1.35V. That's why I was searching for low voltage.Serious question. What's the diff power wise between a 1.35V and 1.5V for 2 sticks? If @Rand__ is no option just let me know.
If the spec on your module is 1.5v, it shouldn't run at 1.35v as most 1.5v modules can't also run at 1.35v, while the 1.35v ones can run at 1.5v.Current 8gb stick I have installed says 1.5V specs, but the system info says, that it's running at 1.35V. That's why I was searching for low voltage.
I found this article from tom's hardware How Much Power Does Low-Voltage DDR3 Memory Really Save?. Quite old and on consumer setup, but I think I'll just install another 1.5V sticks, as (by the article findings) consumption is lowered by ~0.5W per stick in idle. Not much given the price difference.
I could see this happening hence why I was recommending you just get another module of what you have since you can run it at 1.35v.I also found this guy: Dell PowerEdge R220 unsupported memory configuration
Had problem with mixing DDR3 and DDR3L memories and I'm not sure right now.
