I bought the same motherboard (asrock x399 pro gaming mobo) and I installed 7 ram sticks and it is saying 112GB found but only 16gb useable in windows 10 x64. 96gb is "hardware reserved". I tried all the "fixes" online and none of them worked. I still had the stupid hardware reserved/useable memory problems. My cpu cooler overhangs one of the ram slots, only allowing 7 ram slots. That is why I installed 7 ram sticks and I am having problems with the usable ram/hardware reserved.
I ended up moving the fan on the cpu cooler up a bit, so now I can install ram in all 8 slots! I just ordered 1 more ram stick overnight, it will be here Tuesday. I will know Tuesday if the 8 ram sticks will work or not. I am using G.skill ripjaws 3200 ram. F4-3200C16D-32GVK
For what it's worth, I tried installing windows 8.1 and the same problem happened. Now I am back on Windows 10 64 bit.
64gb of ram works great if I have it in A1,B1,C1,D1 OR A2,B2,C2,D2 but I have "hardware reserved" memory problems if I put in 5, 6 or 7 ram sticks in multiple different positions. Right now I only have 4 sticks in A1,B1,C1,D1 and it has 64gb and 64gb useable. It's great with 64gb. I've got the other 3 sticks outside of the machine right now. I know how you guys feel. I spent a boatload of money on this stuff to have a fast computer for my business and it sucks to be having problems. I run virtual machines. I am thankful at least 64gb is running stable. I can get by with 64gb but would prefer 128gb. I will post back here with my results on Tuesday with the 8 ram sticks. *fingers crossed*. Edited by threadrippera - 01 Oct 2017 at 10:53pm |

That sounds promising! But I don't see any 128GB RAM kits for that type of RAM (Gskill FlareX). Any idea where I could get this? I'll buy it now if it'll help! |

The 7 sticks = hardware reserved is likely to be normal due to quad channel memory seeing a non-quad channel configuration. At least, I think so. 6 sticks might work though. That being said, DEFINITELY tell us if 8 sticks of memory works for you. For us, it won't work. This motherboard seems to fail to boot/post whenever 8 sticks populates it. |

Honestly threadripper can use ddr4 @ 2666, i bought ram at 2400 for a budget constraint...thinking to use some memory at 2133 not seems a true goal...
I've tried to force my mems to 15-15-15-35 @ 2133...C0 |

threadrippers, if you want help here, please post all your specifications and I suggest you place them in your signature so we can see them in each page. In general, memory must be purchased in dual of quad kits not piece by piece. The chances of your set up working are slim to none, in my opinion. If you want 8 sticks of memory you should purchase an 8 stick kit. Good luck and enjoy, John.

Really frustrated to see that 8*16Gb conf on threadripper platform is a true nightmare...googling to other X399 brands on Memory QVL I can see that a very few kit are supported.
advertise 128Gb support with 1% of kit supported not seems honest |
