RAM 1.65 v greater than recommended voltage for 1.5 v intel processor. Is that bad?

Should I worry? According to my final build on pc parts builder, the voltage is greater than recommended voltage. What's likely to happen? I understand that I can simply go into BIOS and adjust things.

It says all parts are compatitable and that the above is just something to note.

The memory controller is on the CPU and has been for several generations of chips now. So going over voltage actually is overvolting part of the CPU. Sandy and Ivy Bridge ( LGA 1155 ) need 1.5v RAM and going over DDR3 1600-1866 does not result in any real gains so that's easy. Haswell ( LGA 1155 ) has a newer memory controller and can use higher speed RAM and 1.6v-1.65v kits run easily with it. So while 1.5v may still be recommended the higher voltage kits should be safe.

What are the exact parts?

Ivy Bridge you should really stick to 1.5v-1.6v and going over DDR3 1866 does not improve performance.

So i guess I would need to underclock this? I don't want to replace the memory. it's 1600 for the record.

Let me guess, Kingston? They are the only company still selling low quality DDR3 1600 that needs 1.65v. You can run it but know that it voids your CPU warranty and Intel will not replace the CPU if it damages it. It will probably be fine but that RAM is aimed at AMD users and is not certified for Intel builds. So use it at your own risk. In all honesty you are about 99% likely to be fine.

You guessed correctly. I hadn't known this.
