Issues with the Gigabyte Z790 DDR4 D motherboard have been reported.
Hello everyone, in May 2023 I acquired an Intel i9 13900KF, Corsair Vengence 3600 DDR4 16gb(2x8), along with my Gigabyte RTX 3070 and EVGA 850 G3 Super Nova Gold+ PSU. In July my system suddenly stopped functioning and wouldn’t boot. I noticed a stuck VGA status light, so I assumed the GPU was faulty—well, that’s not important, I’ll just upgrade. I purchased a 4070 TI Super from MSI. The same problem persisted, so I conducted as much troubleshooting as possible.
I re-seated everything but it didn’t help. I tried installing only one RAM stick in A1 and restarted the system, but it still wouldn’t work. The other RAM stick also failed to resolve the issue.
Later, I updated the BIOS using the Q Flash Plus on the motherboard. It appeared the BIOS was updating itself. I wasn’t sure of the original version, but I upgraded from the original to F11d. The Q flash indicator stopped, and after rebooting, the PC kept restarting endlessly. I attempted a CMOS reset by removing the battery after unplugging the system and holding the power button for 15 seconds. I left the battery out for about two hours because I was away from home.
When I returned, I put the battery back in, powered up the system, but the CPU and DRAM lights still appeared. I repeated the BIOS flash and CMOS reset attempts, but nothing worked. I contacted Gigabyte to initiate a return with an RMA. It took three weeks, and they sent me the same board, claiming it tested fine. However, upon receiving it, I found there was no power connected to the board. This might have been unfortunate since the system was restarted just before arrival. I then returned it to Intel for CPU replacement under the RMA. They delivered a new 13900KF on August 22nd. I also bought fresh RAM—32GB Vengeance RGB Pro at 3600 MHz.
Everything seemed normal until September 7th, 2024. The DRAM and CPU status lights were flickering erratically, and the system kept rebooting. I’m unsure what to do next except possibly replace the power supply or swap out the boards. I also tested the board in a cardboard box outside my case and performed another CMOS reset, but it didn’t help.
If anyone has suggestions, please let me know. Thanks!
just try the system with another unit initially.
you should also verify using only iGPU.
if the problem persists, it might be related to the PSU, as it could lack consistent power delivery to the whole setup.
begin by testing DIMM A_2, even for single-channel configurations.
A_2 & B_2 are suitable for dual-channel kits.
I would consider using the iGPU feature though, but since I have a KF CPU that’s not available, it’s not an option for me.
🙁
I went through DIMMA2 and tried all possible slots—each stick individually A1 then A2, then B1 and B2. After leaving the system off for an hour after posting, there were still constant reboots without any CMOs. I’m planning to get a new motherboard tomorrow to test it.
it was important to note that. there are several good reasons to always keep an onboard GPU ready. you might cut some costs during the initial setup, but the troubleshooting value is significant. additionally, it appears more appealing once the system or CPU is unloaded later. you might wish to consult local repair shops to find out what testing options they provide for components. some locations will provide affordable hardware diagnostics, though you could end up paying more with them.
