Its 1.5v 1333mhz 9-9-9 default speed ram. Highly underestimated tho.
I didnt take a screenshot from stability test. I ran Linx on full capacity for 30minutes. It gave me error on 17min with 1.575v but passed 30minutes mark with 1.58v. So thats the voltage i am running it now.
I dont think that anything will happen to this ram under 1.6v in time. On 30min test, the chips didnt even get hot. Just warm enough to be able to touch them by hand. No heatspreaders, no fan blowing on them.
