So I custom built this PC a few months ago. Originally had 2x4Gb of HyperX Fury DDR4 RAM. Worked like a charm. I started running a flight simulator and one of the planes required a crap ton of memory. So I did what I thought was logical and ordered a single 8Gb module of the exact same RAM. Since installing, My PC has crashed 3 times, My simulator has crashed once. I'm not entirely sure what is wrong.

Here is the mobo i have: http://


Here is the RAM I originally installed: http://


Here is the RAM I installed last night: http://


Any Help you can offer would be fantastic. Here are my Specs in case you need to know them.

CPU: I7-6700K (Not overclocked)
GPU: Gigabyte GTX 1060 6Gb
PSU: Corsair CX750M
RAM (originally): 2x4gb HyperX Fury DDR4 RAM
MoBo: Gigabyte Z170-HD3


I also checked CPU-Z, Here are some screenshots of each RAM module

Start with the 8GB stick in slot one, go into BIOS, raise DRAM voltage + 0.05, save exit, shutdown, add the other two sticks in slots 3-4 - this puts 8GB in each channels and will all run in dual channel via Flex mode - if the run. There are NO guarantees when mixing DRAM

Initial thought is that by adding 1 module instead of 2 you are putting it into single channel mode. I cannot determine if that motherboard supports dual channel on one channel and single channel on another but it is unlikely it does. See what it says in the BIOS before you boot into Windows or run CPU-Z and see if it reports dual or single.

Not sure if that is causing the issues but isn't desirable either way.

If you only have 1 stick in, you will only get single channel mode. If you have 2+, you normally get 2 channels, which I believe has a few small benefits, but not a huge deal.

Have you tested the second (new) stick for physical issues? Have you tried booting with ONLY the new stick? Try that and see how it goes. You can also test the new stick with a program called Memtest86 to check for physical issues with the ram.

If the second stick passes an hour or so of memtest with no errors, the issue may just be buying single sticks separately. 'Identical' ram doesn't always play nice, which is a large reason why ram is often sold in kits.

Recommend you check out this thread on the subject, if you read to the bottom you see people listing some potential issues with mixing ram.

There's a total of 3 sticks and where in the BIOS do I check timings/speeds?

I'm not familiar with your motherboard's bios, so I can't give you exact instructions, but the main thing is you need to find a tab with info on your ram, which may be mixed in with cpu info.

It should look somewhat similar to this, http://extreme.pcgameshardware.de/attachments/880782d1455594835-asus-z170-pro-gaming-probleme-rma-und-support-fachidioten-160216023827.jpg please note this is an Asus motherboard though. The information you care about is the frequency, voltages, tCL, tRCD, and the other stuff in the same column of the pic. If stuff doesn't match, it may be possible to manually change them to match.
