Arrow Corsair Vengeance Pro 1866MHz - Need help with OC!

Corsair Vengeance Pro DDR3 1866MHz 16GB (kit)
Partnumber: CMY16GX3M2A1866C9R
8GBx4 sticks = 32GB

Motherboard: MSI Z97A Gaming 7
CPU: 4790k
BIOS: 1.B

It's listed as supported sticks in the OC list:

Anyone can help me with the settings, timings volts etc?
I'd like to get atleast 2000MHz or 2133MHz out of the overclock.

What is the IC version for your kit? ( You can find it @ the model sticker on the heatspreaders. )

Other than that CMY16GX3M2A1866C9R is a 2x8GB kit, not a "8GBx4 sticks = 32GB" one.

No idea, bought Februar 2015, so they are probably from winter time of 2014.
There is two kits, hence 32GB ram.

Check the version number for both kits then. If the versions differ between both kits, that makes overclocking them more complicated. Some ICs will overclock to 2133 and even 2400 no problem, others might have trouble to reach 2000.

For some versions i can give you estimated settings for 2133/2400, based upon their general IC scaling.

Give me the settings for 2133 and 2400, and I'll see if it's stable.

v4.29 and v8.22 are the kits

The Ver4.29 one should do DDR3-2133 11-11-11-28 around 1.5-1.6V and DDR3-2400 11-13-13-31 around 1.6-1.65V. You might even be able to tighten the timings down a bit, but do basic stability testing first. If DDR3-2133 CL11 is possible at or below 1.50V, then you should be able to run them at 10-11-11 or even 9-11-11 with a bit more voltage (CL9 might require more than 1.65V). If you are lucky they might do DDR3-2400 CL10 and/or tRCD=tRP=12 below 1.65V.

The Ver8.22 one will probably not go that high if OC at all, at least i personally never had any luck with 4Gbit Nanya ICs beyond DDR3-2000.
