The system stops sending signals following the installation of a new GPU.
Initially, my components are set up as follows:
CPU: Ryzen 7 5800x with Noctua (DH-12?)
Motherboard: Asus TUF GAMING X570-PLUS
GPU: Gigabyte 3070 Eagle OC with 8GB RAM
Power Supply: Segotep GM850W
RAM: Four 8GB Team Group Delta II modules (two at 3000MHz, two at 3200MHz)
Storage: 512GB WD NVME M.2 drive, one 1TB Barracuda drive, two 2TB Barracuda drives
I had planned to assemble a PC for my girlfriend, so I purchased additional parts and wanted to verify if the RX 570 8GB Armor OC she received would function properly, in case I needed to return it. After installation, the system failed to boot. The fans didn’t spin, there was no signal, and everything appeared operational in the PC but still showed no output on both monitors. I tried reconnecting and unplugging the monitors, power cycling them, reseating the RAM, removing and reinserting the CMOS battery after about 15 minutes, yet no signal persisted. I observed that the DRAM light on my motherboard was consistently orange during boot, never cycling through its normal colors—starting as orange and failing to change—and all RGB lights except the GPUs reset to their default state. I checked an online version of my motherboard manual, but it didn’t reference an orange DRAM light. I’m uncertain what to do next.
Initially, it seems unlikely to have two DIMMs operating at 3000MT/s and another pair at 3200MT/s simultaneously. Such a setup would likely limit performance to four DIMMs at 3000MT/s, which could already present challenges given the existing configuration. This alone might be sufficient to trigger issues, especially since you appear to have two distinct kits rather than four separate units.
Assuming you possess just two kits—each containing two DIMMs rather than four individual units—it’s important to verify that the components are grouped correctly.
Before proceeding, consider removing one kit at a time—whether it’s the 3000MT/s or 3200MT/s unit. Ensure that what remains together forms a single kit, not individual DIMMs from separate kits. Also, confirm that the DIMMs are placed in the A2 and B2 slots, which are the second and fourth positions to the right of the CPU, with the fourth slot closest to the motherboard edge.
When using all four DIMMs, verify that one kit occupies the A2 and B2 slots while the other kit takes the A1 and B1 slots. This arrangement ensures proper dual-channel operation. Any other configuration will not function correctly.
Next, with only two DIMMs installed in the A2 and B2 slots, remove any graphics card from the motherboard, switch the PSU off, and then power down the system. Disconnect it from the wall, remove the CMOS battery for five minutes, and during this time, press the power button on the front of the case continuously for 30 seconds. Afterward, reinstall the CMOS battery.
Once the process is complete, install your chosen graphics card. Reconnect the PSU and restore power to the unit. Turn on the computer and check if it can POST and display a video signal.
BIOS Hard Reset Steps
Power down the device, switch off the PSU, and unplug the power cable from the wall or supply. Remove the CMOS battery from the motherboard for three to five minutes. In some cases, you may need to take out the graphics card to access it.
While the CMOS battery is removed, press the power button on the case continuously for 15 to 30 seconds to discharge any remaining charge. After the five minutes, reinsert the CMOS battery, ensuring it’s oriented correctly.
If you had to remove the graphics card, you can reinstall it afterward, but be sure to reconnect any power cables or display cables.
Reattach the PSU cable, switch it back on, and power up the system. It should display the POST screen and provide options to enter CMOS/BIOS settings. Enter the BIOS setup, adjust boot configurations for Windows or legacy systems, and save changes.
Proceed with saving settings and exit. If the system successfully POSTs, you can continue by navigating into BIOS to configure additional settings such as Memory XMP, A-XMP profiles, or custom fan profiles.
Remember that after a reset, it may be necessary to load default or optimal settings in BIOS to restore hardware tables.
In certain scenarios, especially if the issue stems from a missing video signal, it’s advisable to try a different display type—such as HDMI—to ensure proper functionality. This can help avoid problems with displayport setups or signal failures.
If a display is unavailable, switching to another monitor can also resolve the issue. These alternatives are often effective when visual input is compromised.
I really appreciate your assistance, and your explanation is clear. My DIMMs weren't running at different speeds before, and I had XMP enabled. It's been working well for about a year. I forgot to test with just one stick instead of all four, and it's now functioning properly. After some adjustments, I'm still having trouble getting all four sticks to work. I knew I should replace the entire set, but when I bought my second 2x8, I assumed it would be the same speed and didn't think much of it. I'll keep this in mind for future reference.
You're on the correct route, and you were already moving in that direction before I mentioned it, as you correctly pointed out. That's perfectly fine.
