[SOLVED] ROG Strix X370-F Gaming AMD X370 Boot Issue: Yellow DRAM LED

Dec 2, 2018
Hello all,

I have just finished installing a new build (this is my first time building a system) with the following components:

-CPU: AMD Ryzen 7 Eight Core 2700X 4.35GHz (Socket AM4)
-Memory: Team Group Dark T-Force 16GB (2x8GB) DDR4 PC4-25600C16 3200MHz Dual Channel Kit
-Motherboard: Asus ROG Strix X370-F Gaming AMD X370 (Socket AM4) DDR4 ATX
-GPU: Asus Radeon RX VEGA 56 ROG Strix OC 8GB HBM2 PCI-Express Graphics Card
-Power Supply: EVGA SuperNOVA 750 G3, 80 Plus Gold 750W, Fully Modular, 220-G3-0750-X3
-Storage: TeamGroup 480GB L5 Lite SSD 2.5" SATA 6Gbps 3D NAND Solid State Drive
-Storage: WD 1TB Blue 7200rpm 64MB Cache Internal Hard Drive (WD10EZEX)
-Case: Fractal Design FD-CA-MESH-C-BKO-TG Meshify C Tempered Glass ATX/mATX/ITX Black

After first boot and during the POST the DRAM-Led on the mobo is always on in orange/yellow color indicating an issue with the RAM.

Everything else seems to be working OK. .. mobo RGB, CPU RGB cooler, fans, GPU RGB, the monitor flickers on for a second but then goes into power save.

I have used the recommended memory configurations from the manual: DIMM_A2 & DIMM_B2 (from left to right).

Important to clarify that the motherboard has the sticker "AMD Ryzen Desktop 2000 Ready" on the box thus I assume it can handle the Ryzen 7, 2700x CPU without any need to update the BIOS-software.

To verify that there is not issue with the GPU I have connected my monitor on the onboard HDMI port but still no signal.

Any help is much appreciated.

Double and triple check all connections...especially memory seating.

Try one DIMM at a time to rule out defective memory.

It should support a 2700X since it has the sticker.

Don't bother connecting monitor to the motherboard HDMI ports as they will only work with an APU (2200G or 2400G).
