Mixing 2x4gb 1600mhz ram with a 8gb 1600mhz

[KermitTheFroggy]

So at the moment i have 8 gigs of ram crucial at 1600mhz 1.5v ddr3 dual channel and i would like to upgrade but i'm on a very tight budget and i was thinking if i could manage to get another ram of 8 gigs same company same mhz same CL.

I have two CT51264BA160BJ.M8F working dual channel at slot 1 and 3 my motherboard is gigabyte GA - Z87M -D3H . (can't find the same sticks anymore )

I found CT102464BD160B for 66 euros ( best price from places i can trust ).

I read that it could work with my two old ones working dual channel and this one being single channel called flex(?) i think but i had problems with ram on my early days and as my budget is way low and i can't make my mind to try it or not ...

If i missed some info you might need please ask me!
I mainly game and now that i got a new GPU(1060 3gb) i found my ram bottleneck me ( high usage on pagefile just creates fps drops every few seconds) , or i think that is the problem..

Their no answer.
Anytime you add more memory their a chance it will not work.

There is no guarantee such a combination will work or how it will work if you do get the PC to boot up.

You may need to lower the memory frequency, relax DRAM timings and/or increase DRAM voltage to get such a combination to work. Since the old memory has never been tested with the new memory there are no guarantees.

Yes because it is the truth.
It might work, it might not work, you might be able to make BIOS adjustments and make it work just the way it is that is why their no answer to your question.

2 options buy it and try it, or sell yours and buy a new kit.

It's hard to sell them around here.. Plus they are old :/ any ideas ? I guess i'll try it after i make sure i can return it or something.
