New build: RX 580 card doesn't send signal to monitor.

[Piegoose]

Motherboard: Asrock z370 Killer SLI/ac

CPU: Intel i5-8400

PSU: Corsair CX600 (600W)

RAM: Corsair Vengeance LPX 16GB (2x8GB) DDR4 DRAM 3000MHz

GPU: Gigabyte AORUS RX 580 8GB

OS: Windows 7 64bit Home Premium

Monitor: Samsung C24FG70

This is a new build, beyond the PSU & OS. The CPU, without the GPU, runs and displays fine. The only issue when running on the CPU was that when I tried a few games out (Fallout New Vegas, Oblivion, Devil Daggers) they all crashed. I found that strange as I thought the CPU has onboard graphics, but I don't even see an Intel Graphics hub anywhere.

When I installed the GPU into mobo, it lights up and fans spin, but the HDMI port on the card and on the mobo don't work. I tried putting the GPU in both PCI-E slots, nothing changed.

I'm not really sure what else to try yet. Maybe install the drivers first, then the GPU itself? I don't think it's the OS from what I looked up, and it seems the mobo should support the card. Any help would be awesome!

After looking into this more, I was led to "diskmgmt.msc" which seems to be saying I installed Windows 7 in legacy mode (since the drive doesn't mention "EFI"). I'm not sure if that'd effect the GPU working yet, or how exactly to reinstall Windows 7 in UEFI mode either yet.

Hey, admit not being a fan of ASRock, nevertheless does your MB offer any option to select the primary GPU?
I remember this from Asus.

When the RX580 is not installed you will have your monitor connected to the MB display port and are then using the iGPU of your i5-8400. Who else should you receive a display output? 😉

Well when I put in the RX 580, I don't even get a bios screen anymore - so I couldn't select it while it's inside.

And yeah lol, I did have a feeling it was the CPU getting anything to display at all. I just could've sworn I saw a video with someone playing a game with only the CPU.

The iGPU of your CPU is not that bad, but surely not capable to play smooth HD games. Look at this: https://www.techpowerup.com/240931/amd-ryzen-5-2400g-smokes-core-i5-8400-at-igpu-performance

When you install the RX 580 is it sitting in the PCI-E slot properly and do you have the external power connectors from your PSU connected?

My guess for the iGPU then is it's not compatible with Windows 7 maybe? But it doesn't seem to want to even run 3D games, while I haven't tried a 2D game yet.

I put the GPU in firmly to the point of it snapping in. Screwed it in also, and connected a single 6+2 PCI-E splitter. The RX 580 lights up and fans run.

I just contacted asrock to make sure this card is compatible, which I believe it should be. I should also mention I got a new selection screen when I removed the Rx 580 to run off CPU again. It asked which operating system to boot, with "Windows 7" as only selection. Hadn't seen that before

Single 6+2? A 580 should require 2x8 pins to power.

The manual shows that, but mine only had 2x4 pins.

So would anyone know if this could theoretically be an OS issue if I'm not even getting a bios screen with the GPU, while I am without it?

I just want to make sure I don't have bad card.

Currently I'm trying to reinstall Windows 7 in UEFI mode, as I believe mine was in Legacy based on info in this thread - http://www.tomshardware.com/answers/id-3719780/lots-trouble-install-windows-uefi-mode.html

It can't be OS related as you are not even getting a bios splash screen-something that is not dependant on your OS. Perhaps check your bios settings while using your integrated graphics to see if theres any options relating to PCI-E slots or display graphics priority.

So I just noticed in bios the primary graphics adapter was always set to "PCI Express" instead of "onboard" which I'm betting explains the odd i5-8400 onboard issues I had. However, I'm still having the issues with the RX 580 - but when I unplug the PCI-E power cable it boots bios again through I imagine the CPU. I'm wondering if the PSU is the issue, but 600W seems enough and everything else is powering fine. And if the RX 580 only requires 2x4 pins of connectivity, wouldn't that mean it's pretty power efficient?

But anyways, here's the options I see in bios...

Primary Graphics Adapter: PCI Express
Top Of Lower Usable Dram: Dynamic
Above 4G Decoding: Disabled [I tried enabling it and the GPU still didn't boot bios]
VT-d: Enabled
PCIE1 Link Speed: Auto
[...]
PCIE6 Link Speed: Auto

PCI Express Native Control: Disabled
PCIE ASPM Support: Disabled
PCH PCIE ASPM Support: Disabled
DMI ASPM Support: Disabled
PCH DMI ASPM Support: Disabled

IOAPIC 24-119 Entries: Enabled

Share Memory: Auto
IGPU Multi-Monitor: Disabled

Stupid question but you are moving the monitor connection cable from the motherboard slot to the gpu when you are trying to use it yeh?
Also its not 2x4 pin (as thats used for the cpu connection) but rather an 8 pin(6+2) you are using for power.
Unless I missing something obvious it could even be a bad hdmi port on the card-any chance of using DP instead or even better try the card on another system?

it going to be two issue. one make sure the mb has the newest 1.60 bios to rule out a bios bug. the other issue is windows 7 is missing all the mb chipset drivers for the newer intel mb. your forced to use windows 10 now on intel mb. use your windows 7 code to activate a windows 10 copy on your new pc. from a working pc download windows media creation tool. make a bootable usb stick. in the bios set the bios to uefi mode on sata and boot drives. make sure the bios is set to windows 10 os. install windows 10 and then install the newest intel chipset drivers. reboot and make sure there no missing drivers. power down and put the gpu back in and set the bios to peg/pci....set muilt monitor support to on. it keep both video chipsets on for testing.

Ya I've switched between HDMI outs. I'll see if my office computer is up to date enough to be compatible with the card, I'm guessing its got a weak PSU. I'll look for a DP cable

Thanks! I'll try that now

Deleted my last message. So, I updated the motherboard to 1.60 and set the CSM settings all to "UEFI Only" (the alternate option being "Legacy Only").

I now have bios display with the RX 580! Thanks for that, I was just about ready to return it lol

Okay, so now I'm working on the Windows 10 setup usb.
