R9 380 no boot with old mother board

[rocknexus]

Hey guys. I recently got a new xfx r9 380 to put in my ancient computer. It has a dp45sg mobo a core 2 duo e8500 and a cooler master 750w psu. when I put in the new card it powers on, and gpu fans spin. But no post beep or any display. Bios is fully updated (last update was in Jan of 2010 lol), I've Uninstalled drivers with ddu, tried to boot with one stick of ram, and reset the cmos. Computer gives a post beep without any graphics card, boots properly with the old gpu, but no boot with just the r9 380 or both gpus in. Im thinking its the newer uefi of the gpu conflicting with the older legacy of the motherboard.

Once you get into PCIe1.0/1.0 boards compatibility with PCIe3.0 devices tends to get iffy. Time to replace the whole system, it's not like the Core 2 Duo can handle a 380 anyway

Thanks for the input. I plan to buy a new motherboard and cpu (athlon x4 860k and gigabyte f2a68hm) but the pcie slots on my current mobo are pcie 2.0. Is that gonna make a difference at all?

Indeed it does seem to be a 2.0 board. In that case you can try installing a newer BIOS revision, but if not there's not much you can do

And don't bother with that "upgrade", it's not much better than your current system!

How would one go about installing a bios revision?

How would one go about installing a bios revision?

Go to the manufacturer page (this case intel), search for their support/driver download page for your particular product (varies from manufacturer to manufacturer, but always very easy), and check their BIOS/Firmware/driver section and follow all the instructions listed (often also listed in your manual)

Bios was already fully updated, and it still gives nothing.

In that case, it's either a mobo incompatibility or PSU issue. Time to start thinking about replacement

I just talked to an NCIX tech service person and they said that the card only runs on UEFI firmware, and not on legacy bios. It is indeed a firmware issue, and can be solved with a new motherboard that supports uefi.
