Hi!
I had help building my current computer from an old colleague who knew a lot about what to get (I don't know much). Now I am looking to upgrade with new RAM and a new Graphics Card (looking at gtx 1060).
Intended use of computer is gaming (overwatch, fallout, maybe battlefield 1 if possible?) and photo editing with Lightroom and Photoshop.

My current computer has:
Processor: Intel Core i5 2500K - CPU-Z says it is running: Core Speed 4323.8 MHz if that matters
Mainboard: P8Z77-V DELUXE
RAM: 2x4GB Corsair XMS3 Vengeance 8GB DDR3 PC3-12800 1600MHz
Graphics: ASUS GeForce GTX 580 1,5GB
PSU: Corsair PowerSupply (PSU) 650W Enthusiast Series

Questions:
#1. My main question is what type of RAM to buy? Since I have an older processor and motherboard I just want to make sure everything works while still getting an upgrade since I am swapping out my current RAM anyway. Aiming to go for 16 or 32GB total.

I just want to get as good a memory as I can.

Different options I found:

1600MHz / CL9 /1.5v - what I currently have
1866MHz / CL9-CL10 /1.5v
2133MHz / CL10-CL11 / 1.5V
2400Mhz / CL11 / 1.65V - is this just the best bet for me now?

It seems like 2400Mhz RAM is somewhat cheaper then the rest at the moment. But the price difference is not that large.

#2. Does it matter if the RAM is 1.5V or 1.65V for my setup?
This seems to limit the data rate if it does matter. I found some information indicating that I could not use higher then 1.5V and some that say I can.

I found this for infor regarding P8Z77-V Deluxe:

"..support up to 32 GB of DDR3 memory Non-ECC unbuffered memory running at speeds of 2400(O.C.) / 2200(O.C.) / 2133(O.C.) / 2000(O.C.) / 1866(O.C.) / 1800(O.C.) / 1600 / 1333 MHz."

#3. Does the "O.C." mean that I should only get a 1600Mhz rated RAM and overclock it uppwards? Or that I can get a higher rated RAM directly?

Thanks in advance!

With a 2500K and with the OC you have I'd prob go 2133....2400 is a possible (and can always drop to 2133 if needed). As far as voltages 1.65 is perfectly safe, had a 2500K and ran 32GB of 2133 on it about as long as I had it and the client that bought it is still running it 24/7. Look to either 2x8GB for 16GB or 4x8GB set for 32GB. Had best look on Sandy Bridge with the GSkill RipJaws X and Sniper lines of DRAM
