[SOLVED] Ryzen 7 & memory issues

I seem to be having or have had with my CPU & memory configurations on a new build. Initially, the BIOS had set the RAM to 2133 MHz, when it should have been 3000 MHZ. I had to enable XMP profile 1 to get the RAM to 3000 MHz. That done, I was getting intermittent BSOD with Windows 10, along with various error messages on the BSOD. Another issue I am having is that games either crashed intermittently or just shut down. Company of Heroes 2 in particular. And so, I thought that the issue was my GFX card, which I have replaced twice, with no difference. I've since gone back into the BIOS, and set XMP to disabled, so now back to 2133 MHZ, and no further issues. There is no overclocking on the pc and all drivers are up to date. I'm guessing that there is a compatibility issue with the CPU and RAM, or maybe there is a setting not right in the BIOS. Appreciate if anyone could shed light on this, and how to get the RAM back up to somewhere like it should be. My system components are as follows:

  1. CPU : AMD Ryzen 7 2700x
  2. CPU Cooling : Cooler Master MasterLiquid ML240L RGB
  3. RAM : Corsair Vengeance LPX 32gb (2x16gb) DDR4 3000 MHz CMK32GX4M2D3000C16
  4. Mobo : Gigabyte Aorus X470 Aorus Ultra Gaming
  5. GFZ Card : MSI GEFORCE RTX 2060 Ventus 6G OC Turing
  6. SSD1 : Adata XPG SX8200 Pro 1TB M.2 2280 NVMe PCIe
  7. SSD 2 : 500GB Crucial MX500 2.5" SSD
  8. HDD : Seagate BarraCuda 4TB SATA III 3.5" Hard Drive
  9. Power Supply : Corsair TX-M Series 650 Watt 80 Plus Gold
  10. Case : Fractral Design Core 2300

Sometimes Ryzen doesn't like XMP with particular ram depending what profile set the ram has, people have found manually configuring ram has worked when XMP fails. Im not sure about your ram though if they should be XMP compatible.

Bios update may help improve memory compatibility.

From 1.45 he shows where he disables XMP and attempts to manually set speed. Being a Gigabyte board, your setting arrangement should be similar.

He doesn't actually change the timings or dram voltage, for 3000 set dram voltage to 1.35v and in the list of standard timing controls, put in the 4 timings as follows from top down. Only need to adjust the 4 fields.

I got the voltage and timings specs from here for your model ram.
