ram and mobo compatibility issue???
New build with Ryzen 3700X, Asus Strix X470-F Gaming, GSkill Trident Z Royal F4-3600C16D-16GTRS, Samsung 970 Evo Plus 1TB, Nvidia 1080Ti FE
This is a new build that I've been working on for the past couple of days. I first installed my old 1700 in the board and flashed to the latest 5204 bios. Then ran memtest from a bootable flash drive for about 4 hours (4 full passes) and found no errors. After that I installed Win10 Home, installed the latest chipset drivers, and other drivers from the asus site. Got the OS up to date with 1903 and then started trying to OC the ram as it was still running at 2133mhz. I quickly found out that any speed above 2133 was completely unstable, even DOCP settings would not work. After saving any changes in the BIOS the system would not restart, the case fans and leds would be running but the cpu fan would be off and I would have to clear the cmos to get it to boot again. I then flashed to bios 5007 and started adjusting ram speeds once again. I tried the DOCP setting first and again it would not boot and I had to clear the cmos. I then manually adjusted the timings to 16-16-16-36 and slowly started increasing the speed one increment at a time. I found that if I tried to increase the ram speed by more than one increment (say from 2133 to 3200) it would lock up and require a cmos clear. Every speed adjustment I would save settings and then boot into the OS, run a 10 minute test with OCCT to check for problems and then back to the BIOS to make another speed adjustment. I did that all the way up to 3733mhz where its running now but I still have issues with restarts. Sometimes it will go with no problems and other times the case fans and leds will be on but the cpu fan is off. I have noticed that when it won't restart there is a yellow led lit up in the top right corner of the board that indicates a ram problem. I have found that cycling the psu power resets it and then the system starts up normally with the OC settings. The ram kit is listed on the latest QVL for 3rd Gen Ryzen cpu's but I'm scratching my head and wondering if this is a compatibility issue with the ram and mobo? Or is there something else that I'm missing? Maybe a setting in the bios perhaps? TIA
