MSI x99a SLI Plus + Radeon Sapphire Pulse RX 6600 8 GB - no signal

[michalufnia158402e6]

Hi, I built a pc based on x99a SLI Plus motherboard and recently added a GPU to it (Sapphire Radeon RX 6600 8 GB PULSE). The GPU starts on boot and them during Windows loading its fans stop working and there is no signal from the card.

Has anyone had a similar issue?

My pc is:
MSI x99a SLI Plus motherboard
i7 6900k
2 x DDR4 8GB Corsair 2400MHz
WD BLUE SN570 500GB M.2 PCIe Gen3 NVMe
Thermaltake Littepower 500W power supply

and recently added
Sapphire Radeon RX 6600 8 GB PULSE


The GPU is definitely working as I tested it on another PC.

Thank you.

what PSU was in the other Computer? I am leaning towards the Power supply cant handle the Current draw of your new GPU as the Thermaltake Litepower 500W PSU is a much older design that has split power Rails so it would be nice to find out what the Other PC's Power Supply was!

Hi and thank you.

I thought that too. The other pc was 750W but it has multiple sata and m.2 drives connected as I store lots of photos. The PC in question is 500W but I disconnected everything I could that could potentially draw power. I only left the system M.2 drive, 1 system fan and 1 cpu fan. I took 1 RAM stick out as well leaving only one.

can you try with the other systems PSU to see what happens in your X99 system?

 

[michalufnia158402e6]

That would be my last resort, I'm not excited about stripping it and then redoing it again

you can leave most in place you just need the 24pin, 8Pin CPU and PCI-E Power to test. (no need to move the Whole PSU just the Cables only just put them next to each other and strech them over and into the Connectors) if like that it works then the PSU really is the Problem.

Also what BIOS version board is using?

 

[michalufnia158402e6]

Hi, apologies for the late reply. I got busy with other things.

So I installed a new Corsair CX750f psu which is 750W. This didn't fix the problem so it doesn't seem to a power relatet issue.

My bios version is: E7885IMS.1D0

What OS are you using the AMD RX 6600 may be win 10 or higher only
GPU has a Zero fan mode
Try HDMI do not use any adapters with it

 

[michalufnia158402e6]

Thanks. It's Windows 10.

I just updated Bios to the latest version I could find which is E7885IMS.1F2.

Still no luck but after updating Bios, in actually started loading Windows and went into the repair mode after scanning the C drive for problems. The repair mode didn't repair anything, then it restarted and now I'm back to square one. It goes past Bios and the GPU turns off.

Could it be a drive related issue? I'm using WD BLUE SN570 500GB M.2 PCIe Gen3 NVMe as a system drive. But then it all works fine with a different GPU.

Thanks.

GPU has a Zero fan mode

Can that be set in Bios? I can't seem to find it?

 

[Alan J T]

Can that be set in Bios? I can't seem to find it?

NO is in AMD software in Windows

What GPU was you using before could be a driver conflict.
May be best to place old GPU back and boot up and run DDU remove all drivers for all GPU in PC and then install the new one or use the Built in IGP that is on CPU

Thanks. I did that before I ordered a more powerful PSU. I might try again.

Here is a quick video of what it is doing:

Did it again and didn't help.
I ran startup repair again which managed to boot into windows using basic display drivers. I then I went into the safe mode, ran DDU, restarted, installed the new driver from AMD website which is Adrenalin 22.6.1.
After restart I'm back where I was which is, it's not booting into windows and the GPU shuts off going past Bios.

It's completely normal on modern cards that the fans are not spinning in idle. As has been mentioned, this is the 0dB-fan-mode or idle fan stop. So this is not an indication of the card "shutting off".

Check in your BIOS that Boot Mode is on UEFI. If it's on Legacy, it could be that your graphics card has no VBIOS (difficult to explain, just test it). However, when you set it to UEFI, it could be that your Windows doesn't want to boot anymore at first (you will get the BOOT LED on the EZ Debug LEDs edit: nevermind, your board is pre-EZ-Debug-LEDs). But that can be fixed.

Thanks a lot. I changed to UEFI (It was set to UEFI + Legacy). Now as you said Windows won't boot. It goes back to Bios when trying to boot.

Ok, now you have to do an "MBR to GPT" conversion for the boot drive, see here.

Thank you. I went and did a clean Windows install and converted from MBR to GPT. Windows installed fine and booted with a default display driver. I then went to install the AMD driver and it shut down at some point during the installation and won't boot again. Same thing. I guess converting to GPT is good in the long run anyway but for now I'm stuck with a GPU that doesn't want work.

It's completely normal on modern cards that the fans are not spinning in idle. As has been mentioned, this is the 0dB-fan-mode or idle fan stop. So this is not an indication of the card "shutting off".

Noted. However when the fans stop on the GPU, the monitor returns a no signal message telling me that the GPU is off? Am I right in thinking so?

 

[citay]

If the fans keep spinning with no driver installed (during Windows installation etc.), it could mean the fan stop in idle is coupled to the driver somehow. Then as soon as the driver is loaded, the fans turn off like they should, but at the same time there is some other problem and you don't get a picture. Or it could be like you said, and the card "turns off" somehow. Hard to say at this point.

You need to find the culprit now. Either test your RX 6600 in a different PC, or test a different (modern) GPU in your PC. Depending on what combination works, we'll see what to do next.
