Question HP Pavilion won't post with new graphics card installed ?

[justinbieber16]

Hi I have an external system, specifically an HP Pavilion P7-1017c with an i3 2100 and 6GB DDR3 ram.

I bought a Radeon R5 340X GPU but putting it in the pc won't even post anything on the screen at all.
But taking out the graphics card get it into bios just fine.

The computer also did post with an i5 2500k but said it wasn't supported and then shut it self off.

Any help would be much appreciated, thanks.

The bios version is 2.10.1206 American Megatrends

Edit: The Radeon R5 340X does post in my main system just fine, so I don't understand what's going on.

It's not a whitelist problem like the CPU, but a compatibility one.

You have BIOS version v7.16 which is not UEFI.

Many modern cards technically do have a hybrid vBIOS which is supposed to work on both Legacy BIOS like yours, or UEFI but got increasingly hit-or-miss by Pascal or GCN. R5 340x is only 1st gen GCN and does seem to work in some Legacy BIOS boards though there's no rhyme or reason why it seems not to in others. I got the 4th gen GCN RX580 to work in one Legacy BIOS board ( it doesn't work in many others), but if you want it to just work I suggest Maxwell such as GTX 750Ti

I'm not really looking to get a GTX 750 Ti at all, I'm kind of limited on money and the only reason I got the 340x is because of how cheap it was.

Is there any way to get it to work on a legacy BIOS?

No, and HP never did release a 8.x UEFI BIOS for that machine. Normally you could boot from the IGP and still use the card for a secondary display, but HP disables the IGP when a GPU is installed.

If you don't mind no more driver support and don't need much performance, nVidia Kepler (like GT710) or AMD TeraScale cards (like HD6450-R5 235X) should work and have been ~$5 used for half a decade now. Surprisingly some of these are still sold new for 10x more.

BTW, is there a reason for the GPU? Something like the HD6450 is actually slower than the GT2 IGP in the 95w 2500k, though faster than the GT1 in your 2100. If VGA + DVI is sufficient, you could just get a faster CPU.

Your motherboard appears to support 65w Sandy Bridge + the only quadcore one with GT2 is i5-2405S. HP doesn't support unlocked k processors, and the 65w 2500S and 2600S have the same GT1 as your present 2100 but are options if you will add a GPU.

Well I'm running it as a server and it has Arch Linux installed. I'm just looking to get a GPU to get a better signal out since my monitor's DVI port is rusted and loses signal every 10 seconds.

Edit
I do have a Xeon CPU for this socket but I'm unsure if it would even work and it would need a graphics card anyways if I wanted to use it.
