RAM voltage GT 683DX

[Gidorra]

I can't seem to figure out the voltage of my memory. I used the usual advisor tools, e.g. Crucial, but it then suggests to me RAM with either 1.35V or 1.5V. I do not want to have mixed voltage modules in my machine - can you guys tell me what you've stuck in there?

When your system has DDR3 modules, it will be JEDEC compliant DDR3 memory modules built to run at DDR3-industry standard operating voltage of 1.5V +/-0.075V.

Actually, you should not want to have any configuration of mixed memory modules in your machine but ideally a set of matched memory modules that are identical in terms of brand, model name, specifications, chip configuration and voltage.

I have yet to see matched sets of 4 modules. Of course, I could buy 4x4GB (2 matched pairs), which isn't too bad either, seeing how 8GB are only like 30 queen-heads. But still, they wouldn't all be matched. Anyway, even if I were to buy 4 modules, I wanted to know about the voltage, so thanks!
