1.65v 2400mhz RAM, underclocked to 2133mhz, should voltage still be 1.65?

Please don't tell me to use XMP and let the bios adjust the voltage automatically, because everytime I do, it sets it to 1.5v and every program I open crashes after about 5 seconds - 5 minutes.

I really need some help from someone who knows what they're doing, the voltage at the RAM sticks is set to 1.59 right now, and nothing's crashing (I haven't really loaded anything that would stress the RAM) , but I need to know if I can set it to 1.65v safely. If not, I'm simply going to return the 4 sticks and buy 2133mhz ones.

(Motherboard is a 990FXA Gaming, which only supports 2133mhz RAM, in case you were wondering why it had to be underclocked)

Why would you return the memory when it's working just fine and using less power?
Memory is just like a processor in the fact that if it's underclocked then it don't need the stock voltage either.
Run memtest and if everything passes their nothing else to do.
Since the memory is 2400MHz and your running it at 2133 you could manually tighten the timings and set it to the voltage needed to keep it stable.
