Gigabyte AX370 Gaming K5. Let me just say that I'm not a fan of Gigabyte motherboard. I upgraded my PC last year and went to AMD for the first time. I got lazy and for the first time ever didn't choose my own motherboard. I went with same choice as a friend because we thought it would be easier for me to share my overclock settings with him. So I've had a love/hate relationship with the AX 370 Gaming 5... nevertheless... it is stable, looks nice and overclocks perfectly well. Has improved with bios updates. So I assumed the Gaming K5 would be a similar story... not too much difference in price. K5 still costs over £138+ It's not the cheapest nor is it a higher end board. Anyway... since I built that PC for client last October with Gaming K5... he's had nothing but trouble. Crash crash crash. Eventually a few months ago it stopped working completely. It booted up twice when I went over to look at it and remained dead since then. I guessed it was the CPU VRM. RMA to gigabyte... replacement board... now I have an 80mm fan blowing over the VRM. CPU is liquid cooled. The K5 has been failing to post properly if the ram is set anything above default 2133mhz. https://www.overclockers.co.uk/team...al-channel-kit-rgb-black-tf1d4-my-08m-tg.html 3200mhz nighthawk. The ram is not on the QVL list for the K5 mobo. That in itself doesn't mean failure as my own Gaming 5 mobo has 8-pack 4000mhz ram not on the QVL for that mobo.. no issues at 3466mhz. The 3200mhz nighthawk WILL NOT post properly on either the K5 or my gaming 5 motherboard. Someone at OCUK told me the 3000mhz nighthawk IS on the QVL for gaming K5. Here's the weird part... the 3200mhz ram was running at the full 3200mhz on the K5 that died. The replacement K5 will not work with it above 2133mhz. scan computers tested the motherboard and found it fully operational with corsair LPX 3000mhz. So I currently have a working motherboard for client that I hate. And 3200mhz ram that is also fully operational (passes windows diagnostic). I can't return the motherboard or the ram because they're working! Just not with each other. There's more... The Gigabyte Ax370 gaming K5 has the worst bios I've ever seen. Most overclocking features removed... I questioned giga support about this and they said those features are removed because it's a budget board. So I explained that every other brand motherboard at £138 has FULL bios overclocking features! I will be reviewing the gaming K5 on my youtube channel. If anyone has some Teamgroup nighthawk RGB 3000mhz... I'd be happy to swap it for the 3200mhz nighthawk ram (16gb).
