Question No boot from a new Powercolor 7700 XT (2nd one)

[vipe155]

Hi everyone,

I've run into an issue I've never had with new hardware before.

My specs:

• Motherboard: ASRock B550M Pro4
• CPU: AMD Ryzen 5 5600
• RAM: Corsair Vengeance LPX 16GB (2x8GB)
• DDR4 Video Card: Powercolor Fighter 7700 XT
• PS: Corsair RM750x 80 PLUS Gold
• Operating System & Version**:** WINDOWS 10 PRO 19045.4651
• BIOS Version: 3.40
• GPU Drivers: 24.7.1

So, my previous card is an ASRock 6650 XT. I got a good deal on a 7700 XT and went for it. But the 7700 doesn't boot in my system. It spins up for a few seconds and then the whole system tries again over and over. My 6650 works just fine.

This is actually my second card because I figured (for the first time) I ended up with a DOA part. But the second go at the 7700 XT does the same thing. I can't figure it out, this should be a simple swap.

My BIOS is updated to the most recent version. I'm using two separate cables for power to the card. The only odd thing (clue?) is that with the 7700 installed and attempting to boot the red LED POST light for the CPU is still on for some reason.

What cables are you plugging into the GPU? (example: ATX 12V Power Connector(refer to your motherboard/manual)

Just the standard 8-pin PCIE cables. My 6650 XT uses one 8-pin, and the 7700 XT uses two. And I'm using separate cables for that, not one split cable.

Is it that one?

Yeah, I have a CPU labeled cable going to the CPU/Motherboard, and PCIE cables going to the video card. On this power supply the PS side is either CPU or PCIE.

You claimed that you updated your BIOS, does your previous graphics card boot with this new BIOS? If it does, have you tried using one cable for this GPU? Is everything seated properly? Check power cables if they are seated securely. Unplug plug back in. Did you get a red light for your ram as well or just CPU?

Is your screen showing anything or is it stuck on POST?

Stuck on POST. Just continually cycles, and the CPU red LED is on, unlike with my 6650 XT where the system cycles on, LEDs cycle through the check, and then go out when it boots.

Did you try what I said above? I strongly recommend you give all those options a try and come back after
