Can I mix ram with the same CAS latency and Timings but with different voltages and sizes?

I have 2 4gb sticks of evga ram and i just bought 16gb(2x8GB) of corsair vengeance pro ram. they have the same timing and cas latency and the same speed. But the only difference is 2 sticks are 4gb and the other two are 8gb and the voltages are 1.5 and 1.65. I know ram compatibility was more of a problem with DDR2 sticks and that more mother boards just under clock the to match the smallest dimm. But i want to be sure. My MOBO supports ram overclocking. so can i just under clock the 1.65v sticks to 1.5v?Will i have to physically change it or will my MOBO do it automatically? I don't see the sizes being a problem with dual channel. but
I'm hardly an expert.



****UPDATE**** Turns out the voltages were mislabeled on microcenter.com I went to corsair's website and the voltages, timing, and cas latency all match. the only difference is the size of the sticks.

It a crapshoot, they might play, might not - abnd if they do play it will probably require you to manually set up the timings and voltages, will help if needed, but there are no guarantees. Always best to get the full amount you want/need in a single package

Well that being said. what are the repercussions if it doesn't work? I wont fry my sticks or mobo, will I?
