7800x3d
7800xt
NZXT B650e Motherboard
Teamgroup T.Force 32gb RGB RAM
W.D 2t.b m.2 SSD
Samsung 970 2t.b m.2 SSD
DeepCool 240m AIO
Corsair RM850e PSU
(I’m using cable extensions and the Corsair iCue RGB accent lights if it matters)
The computer powers on internally, GPU lights up, fans spin on the AIO but not the GPU or case fans. (I’m pretty sure I left the fans unplugged for too long while working all day; I’ll fix that next time.)
Not sure if the GPU fans stop when there’s no load. CPU and DRAM indicators stay red. The monitor is brand new and working fine. I haven’t tried standard troubleshooting yet, but I swapped in the RAM and it’s correctly seated (2+4).
I’ve left the system running for over ten minutes to see if it boots, plus used the CMOS and BIOS flashback button (not sure if that was enough).
Tomorrow I have to start early, but I’ll check for fixes when I’m home. I’ll test if a RAM stick is faulty and post results with CPU integrated graphics, if any help comes up.
I have received the money back and am awaiting my replacement part. MemoryExpress told me the board was working again (oops). Apparently, after five failed boot attempts, they had to clear the CMOS by removing the battery. I only reset using the button on the motherboard and followed the manual instructions. It seems like I'm just being simple, but thank you all for your help. It was an interesting and slightly stressful experience, but everything is now sorted out. Very grateful the return was easy and they didn’t blame me for my mistakes.
Consider testing the setup with minimal components, using a breadboard without additional splitters or extensions.
Check the CPU socket for any bent or damaged pins.
Identify which two slots the RAM sticks are connecting into on the motherboard. Could relieve pressure from the AIO in the socket and potentially improve system performance.
Is this your motherboard?

? If so, I dont believe it supports the 7800x3d. It is not listed on their compatible cpu list but their support page is a little confusing to be honest, there's no information on the BIOS updates to tell you what they actually do?
I checked various forums and found that it supports the CPU, though a BIOS update is required. I'm not sure which version to use.
Hi, I did my AM5 build last week and I understand what you're saying.
Just to clarify:
Use one stick of RAM in the A2 slot and try booting. It will take you to the post screen with three choices:
1) Press 'Del' or another button to enter setup – I tried this and got stuck on that page for 30 minutes, nothing happened.
2) 'Y' to enter UEFI boot with drive encryption – doing this will get you into the BIOS, where you should update your BIOS and set the expo profile. The single stick will run at around 4800MHz.
3) 'N' to enter shell mode – you could also do a BIOS update if you have the USB stick with the BIOS files.
The post screen might look slightly different depending on the MOS. If the options aren’t the same, can you take a picture and share it here?
I plan to try some suggestions later tonight, around 10-12 hours, and another update will follow then.
The company checked for bent pins before sending, and I double-checked before inserting the CPU. I’ll also try posting from integrated graphics, but I’ll save the CPU/socket check for last since I’m concerned about removing it and want to troubleshoot other issues first.
I’m using cable extensions for my GPU CPU and MB—your advice? Try without them? Or plug the RGB accents via SATA even if power is going there? Or are the fans (case fans after a third boot) sufficient?
I also read these should be compatible and didn’t show any issues in PcPartpicker, though I might have been misled. If a BIOS update is needed, is it done through BIOS flashback? Do I need to install anything on a USB drive, or just press the BIOS flashback button because I pressed it but got nothing else?
I’ll test using one stick of RAM to see if it’s faulty, though this is my first attempt at PCs and I shouldn’t change the expo settings. Unsure, but I’ll follow your instructions carefully. I was told to start with "B2" in the motherboard manual—probably A2+B2 (I don’t have the manual). The 2nd and 4th slots were where RAM went, but I’m not getting any post results, so I’m unsure if these steps are correct.
the requirement for one stick is not meant to test for faulty ram sticks. if the ram isn't set up as a dual channel kit or expo settings aren't active, it won't post with two sticks installed. you'll see a DRAM LED blinking in the post error debug lights. you won't be modifying the expo settings; they remain off by default, and the standard speed is 4800mhz. just turn on the expo settings and select your saved profile in the ram, and it should work. it's usually A2 – the second slot for posting with a single stick of ram – as noted in your motherboard manual.
Understood, I'll verify that as well, though I'm still a bit uncertain about any changes.
