Question mixing ram with different voltage

Hi,
I have a old pc runs on ddr3 ram. Originally i hae installed a 1600 mhz gaming ram on it. However the motherboard only supportes 1333mhz. Today i have buy another ram with same speed but its having different voltage. The old one runs 1600 mhz@1.65 v. The new one runs 1600 mhz@1.5v .have i get any problems when install these two at once ?
 
Well, if your mobo only supports DDR3-1333 (JEDEC setting), it's probably @ 1.50V at that setting, so assuming that's true, then you should be able to pop in both additional sticks, and not worry TOO much. If it works, it works.

Is that motherboard shows the current ram voltage?
 
I have installed and it wont boot with both rams.. both is ok as installed in single. Dont know what happens . The ram modules are different in sizes too..the new one is just half of the height of older one(1.65v one).
 
It sometimes works but typically mismatched memory sticks is a bad idea. I've had instability due to it in the past. It even seemed like it worked fine but every once in a while I'd get a BSOD for memory related reasons.
 
Yeah depending on motherboard, it may be more picky about RAM compatibility, especially when using different voltages. What are the system specs?

Its old one. Asua h61 motherboard with i3 2120. No graphic card attached.
 
Ok, going forward, for that I would try to stick with 1.5V DDR3 anyway, as 1.65V was fine with the 1st gen architecture, but with Sandy Bridge (2nd gen) and newer, Intel recommends 1.5V (or sometimes less) for the RAM voltage. Luckily, 1.5V DDR3 is pretty cheap, so I would stick with that. Try to get a similar kit too, if you are going to mix. You can always look on Ebay or other places for cheap used DDR3.
