Avexir 2133 2x4Gb with i5-4670K AsRock Z87 BSODs?

[Rival Son]

So I've had a few BSODs from time to time.. Never thought much of it, then I had another and decided to look into it since the PC is less than a year old.
http://uk.pcpartpicker.com/p/VfkhdC Full system build (current)

From PCpartpicker, I did notice this before buying, but after a little looking, most put it down to their over caution.

Compatibility Notes
The Avexir Core series 8GB (2 x 4GB) DDR3-2133 Memory operating voltage of 1.65V exceeds the Intel Haswell CPU recommended maximum of 1.5V+5% (1.575V). This memory module may run at a reduced clock rate to meet the 1.5V voltage recommendation, or may require running at a voltage greater than the Intel recommended maximum.

So I ran WhoCrashed after this latest BSOD and it suggests that my issues could be memory related, and after running through some forum posts, a few other mentioned similar issues with 2133 on Haswell.

After checking with CPU-Z I could see it was running at around 800 MHz, and so a few more forum posts later it seemed I needed to change the settings in the BIOS, so changed them to the 11/11/11/31 as specs state. Now is showing 1066.5 MHz (2133 MHz).
I'm just worried the voltages may not be correct or it might reduce the lifetime of the parts,

Any help/ suggestions welcome.
Thanks

Do you have any OC on the CPU at all? Try raising the VTT + 0.04 (might be listed as CPUVTT or DDRVTT - it's the MC (memory controller) voltage)

Couldn't see any of those, but this is what it was showing when I booted into the BIOS.

Try it to the VCCSA (system agent voltage offset ( + 0.04)

How it looks now. Will see how it copes.

Another two crashes in the past day :/
Any ideas? Got the additional information from both and from all my previous crashes if need be?
Thanks, Rival.
