Hi guys, got the 1700x on a gigabyte ab350m matx board with hyperx 2x16 gb 2400mhz ram and getting some problems. First symptom came with win10 installation was super slow but eventually finished. Then would get intermittent non boots, maybe 1 out of 10 reboots would get stuck at the mobo splash screen. Hard reset with power button would make it work. Next is the super high temp readings, idle at 55-60c, prime95 over 80c beeping all over. Finally the random laggy system on random reboots. Opening menus or doing anything in os became super choppy with occasional lockups and crashes. When it's choppy, cpu bench in Cinebench drop by 300 points and gpu fps results drop by half, although clock speeds seem to remain the same. Reboots solved this. All voltage seems normal reported by gigabyte's SIV hardware monitor.
Everything is set to stock with newest bios/drivers. I know it's not the vid card, or psu as they were perfect before i swapped the mobo,cpu,and ram in. To rule out the ram i ran memtest86 for 2passes quickly just to see if any errors. So now it's down to either mobo or cpu problem, chances of cpu being bad are rare, so I'm thinking the mobo has some issues. Was going to try and set the ram to 2133 but F2 bios is not allowing me to change anything.
Side note, I pulled one ram stick so only running on 1x16g 2400 ram and the system seems more responsive and have yet to crash. Tried both ram sticks separately on slot 1 and slot 2 and neither has crashed nor felt choppy. Problem with the board and running dual channel ram? Going to put in 2 sticks again but on slot 3 and 4 this time to see how it goes.
Anyone else with this board and similar problem? Or anyone WITHOUT any problems and can confirm mine's a defective board rather than the whole lineup is having teething issues?
