Issue: Gigabyte AX370 Gaming K7 with Kingston Hyperx Fury HX421C14FBK2/16

I am trying to pair Gigabyte Aorus AX370 Gaming K7 with Kingston Hyperx Fury HX421C14FBK2/16 and the system won't even boot with that ram (Tried dual and single channel with all 4 slots in all configurations). The system will boot up with 1 stick of 4gb (F4-3000C15Q-16GRR) and runs perfectly, but won't with the HyperX Fury.

System Specs:
Win 10 Pro (64bit)
RAM as noted above.
AX370 Gaming K7
Ryzen 5 1600X (@ stock due to ram issue) w/ 212 Evo
Kingston SSDNow V300 120Gb
Seagate Barracuda 1Tb 7200 Sata.III
EVGA GTX 680
EVGA 600B PSU

-I know that HX421C14FB2K2/16 and HX421C14FBK2/32 are supported, so I don't see a problem
with my pairing the HX421C14FBK2/16.

-I've checked the RAM in another system and run a memory test and it passed the test and worked in that system.

Have any owners of the AX370 Gaming K motherboards run into this problem? If anyone has a solution, please let me know.

Gigabyte and Kingston support are just about useless and can only blame the other and say RMA it, but there is no problems with either motherboard or RAM that I can find and both work with other systems.

PS. I've tried bios updates F4 and F6.

  1. FYI, the HX421C14FB2K2/16 is single rank rams while the HX421C14FBK2/16 is dual ranked rams.


    You should also be on BIOS version F7a which contains the much necessary AGESA code if you'd like to go past DDR4-2133MHz on your ram.

    Also, don't mix and match ram sticks/kits. I'm assuming you used the G.Skill ram to test the system's integrity but after you get the BIOS update through(while on the G.Skill) swap the rams out for the Kingston kit.

    Yes, I attempted to initiate it as single rank with one module, but it didn't work which is why i listed the fb2k set. In theory it should work, but for some reason i got the short end of the stick with this pairing.

    Correct, I'm only testing and updating with the G.Skill stick until I can figure out the problem. I may just have to RMA the RAM and go with another kit.
