Hello
I am assembling a build with these components: AMD 7900X, Gigabyte X670 Aorus AX Elite, Corsair Vengeance 32gb 16gb x2, and EVGA GeForce 3080.
Following the motherboard manual, installing both RAM modules in the second and fourth slots prevents the system from booting, with no POST or BIOS activation. No system beeps occur. The CPU indicator lights up briefly before switching to DRAM, then to VGA, but nothing further happens. Fans and RGB remain active.
When I install RAM in slots one and three, the same issue persists.

I am attempting to set up three monitors: one via HDMI, the other two using DisplayPort. The computer boots normally with only the second slot having a RAM module installed, but only when paired with the HDMI monitor and one DP port connected. Connecting the remaining DP port halts the boot process. Removing it restores normal startup.

The GPU is unplugged, and onboard graphics activate the VGA light; the Aorus splash screen stays on even after pressing del or F12. There appears to be a problem with holding the power button down while the DRAM light is illuminated. Front fans slow down, RGB stays on, and the light transitions back to CPU once the power button is released.

Windows and BIOS detect all components.
What I have tried:
- Updated BIOS
- Updated GeForce drivers
- Applied latest Windows updates
- Swapped DisplayPort cables; one port on the 3080 doesn’t register
- Reset CMOS switch

Help needed!

Is it possible for the machine to start if you install the additional DIMM by itself in the second slot? Have you taken out the processor to check if any of the connections in the socket are damaged?

It appears the RAM module is defective, causing the system to start up using just one slot. Are there additional steps you can take to verify this? Also, could you check if the CPU connections are intact? The RAM pins seem normal.

When you download a copy of MemTest86+ and follow the steps, you can start the computer via USB and keep it running for about an hour or two.
If MemTest detects issues with XMP disabled (meaning no memory overclock), then the RAM might be defective. It's common for MemTest to report errors even with good RAM when XMP is turned on, so ensure XMP remains off.
After buying the memory, return both units via RMA and request a replacement set. Mixing DIMMs from different kits isn't recommended as the second stick could be delayed.
Did you follow the ESD (anti-static) handling guidelines during PC assembly?
