All games crashing on new build

Recently upgraded my pc to Ryzen 5 (specs below) and now every game crashes on start up or regularly when playing. No idea why and even on the lowest settings, most games won't even load.

Worst example is Minecraft, I get bad stuttering and freezing when using 2x sticks of ram in dual channel but it's fine with only 1x stick. Also the resource packs glitch/don't render properly most of the time. (Didn't get chance to try other games).

Pc:
Amd Ryzen 5 2600x
Asrock b450m pro4
2x8gb hyper X 2666mhz
Palit Gtx 1060 super Jetstream 6gb (latest drivers)
Kingston 240gb sad
750gb Samsung hd
Corsair 600w CXM PSU

Any help would be apreciated
 


Apologies I have fat fingers and accidentally down voted your reply on my phone!! Thanks for replying so quick.

I have tried the ram in both 2 & 4 and 1 & 3 to be sure but it yields the same results. I am having trouble with memtest86 as it will not load. I just get a black screen and nothing loads when I boot from usb. The windows memory test was ok but I doubt that is the most reliable test.

Memory modules such as the one listed above that are sold as Singles have no guarantee to be compatible in any configuration other than as a Single module. Memory is guaranteed in the form sold. Other combinations you decide to make have no guarantee to be compatible together. This includes exact match, same thing, identical.

Use of exact match, same thing, identical may raise your chances of getting the memory working together over that of using random modules.
 


Hi, The kit I purchased was: https://www.amazon.co.uk/gp/product/B06XNT2M23/ref=ppx_yo_dt_b_asin_title_o00__o00_s00?ie=UTF8&psc=1

It was a 16gb Kit so I assume they will be compatible?
 


I have tested using Memtest 86 and found no errors over 3 passes (one on each dimm, and one on both at the same time)
 


Hi, This was a fresh install of windows 10 after the hardware change.

Running perfectly on 1x stick of ram now
