Hello everyone, I’m facing a recurring issue with many older boards when trying to use a newer GPU like the RX 470. I’m testing whether slightly updated GPUs can run on budget motherboards for cryptocurrency mining. So far, I’ve tried three different boards, each with distinct problems. All needed three PCIe slots, and here’s how I’ll structure my posts: board in use, setup details, issues encountered, my reflections, and possible fixes.
I’ve already reset everything—CPU, RAM, GPUs, power connections—and updated the BIOS. I’ve used one GPU at a time, paired with a second PSU for cards two and three, and even tested the GPUs on another board to confirm they worked. All components passed initial checks, and I verified other parts too.
My main observations:
- The motherboard doesn’t trigger a proper POST beep.
- No display appears regardless of GPU used in the X16 slot.
- Removing the PCIe x1 to x16 riser didn’t help.
- When RAM was removed, it would normally produce three beeps.
- A recent BIOS corruption forced a repair, after which it worked briefly before recurring issues.
My reasoning: It seems the BIOS might not recognize the card slot, or there could be a limitation in PCIe lane allocation. I suspect the board may be running out of lanes, and changing its configuration might help—but I can’t access the BIOS for the X16 slot.
I’ve also learned that older chipsets managed PCIe differently, and modern cards sometimes need specific settings. The fact that other boards worked before suggests compatibility issues rather than hardware failure.
If you have any tips or insights on this, it would be greatly appreciated. Thanks!
The Radeon RX470 requires UEFI BIOS, so you must use a motherboard that supports UEFI to boot it. The H61 board allows booting into BIOS with the integrated GPU. Adjust the setting named PCI ROM Priority to "EFI Compatible ROM" and then install a UEFI operating system for proper functionality on the H61 board.
Here’s a revised version of your message:
Thank you for your reply. I believe the post was probably too lengthy for many readers, yet I aimed to clarify my current situation. Still, I recognize worries about compatibility with older BIOS and UEFI features on the RX 470. Most VBIOS appear to function adequately with legacy systems. I saw several online discussions suggesting the card should work without issues, and it did seem to operate properly on my DG45ID board up to a certain point. I thought UEFI might have a compatibility setting that would resolve this problem. The H61 board is a Lenovo OEM model, which would make things much more complicated for me—especially trying to recognize multiple cards. I’m also convinced the firmware makes it nearly impossible to use such options. Overall, the BIOS is quite basic, so the solution you mentioned doesn’t seem viable.
