I've discovered, after many years of instability, that my Gigabyte Z87-D3HP doesn't like 4 sticks of RAM and has been the cause of many headaches (i've tried many of the 'fixes' but the only fix that works is taking out 2 sticks, doesn't matter which 2).

So i'm intending replacing my 16GB of Patriot 4x4GB 1600MHz with a 2x8GB setup.

I've found some Kingston HyperX Fury 1866MHz for a reasonable sum (i.e. cheaper than the 1600MHz sets I had been looking at) but just want to check it won't cause me any other untoward issues and it will simply slot in and the BIOS will sort out what it needs to so that everything runs happily?

If it makes a difference the CPU is an i5-4670K (not overclocked because the PC was never stable at stock, now I know why I might clock it a bit!). Would it make overclocking any more or less easy with 1866MHz in there rather than 1600MHz?
 
I've read a few guides since recently switching to Haswell that high memory can limit an OC but personally even if I set my memory to 1600 (2400 at stock) it doesn't help me OC any higher.

As for dropping it in and the system just working. You will be better off just making a note of sata settings, boot order plus any other custom settings you have like Fan profiles and resetting CMOS before install the new RAM.

Just a quick thing to try to possibly save you unnecessarily spending money. Try loosening your CPU cooler a little bit has worked for me. Also set the RAM command rate to 2.
 
The stability issue is 100% due to the 4 sticks of RAM, it was only since moving house and starting to use the PC again that I looked into it again and it is seemingly a well documented issue that Z87 Gigabyte boards struggled with 4 sticks installed rather than 2. Taking 2 out (either pair) and the system is absolutely rock solid. 4 sticks in and I can manage about 5 minutes of gaming before it locks up. There are many 'fix' guides involving RAM timings, altering tRFC, tFAW and tRRD etc. but none have worked for me.

The CPU cooler has been refitted recently (Raystorm water block) and made no difference, though the money saving suggestions are appreciated!

So essentially, there's not really a downside to having 1866MHz as I could just run it at 1600MHz if needed anyway?

You can probably tell i've fallen out of the loop a bit since building this thing a few years back.
