    Why won't my R7-370 work on my Intel DP45SG motherboard?

    clutchc

      I have a GTX 960 working fine on my DP45SG board.  But when I change to my R7-370, there is no display, no beep.  However the R7-370 works on another (MSI) 775 board I have with no problems.  So I know the card is OK. 

       

      Q9550

      Intel DP45SG (latest BIOS)

      4x2 GB DDR 1333MHz memory (PC3-10600U)

      Corsair TX650M PSU

          In a nutshell, your board is so old that it is likely incompatible with many of the emerging video cards. The firmware on the video card may be expecting the board's BIOS to provide certain capabilities - some of which might not have existed (other than as emerging specs) when your board was released. Further, some of the video cards expect that the board's hardware has certain capabilities. For example, some high-end video cards expect the board to support PCIe 3.0. Yours might only support PCIe 2.0.

           

          A common problem is video cards whose firmware only includes a UEFI driver; they do not provide legacy Op ROM support at all. I cannot remember where we were with UEFI in the 4 Series board generation. Check your BIOS and see whether there is an option to enable UEFI. Enabling UEFI may get you through POST. I warn you though, you might not be able to boot into an existing Windows installation (i.e. you might have to reinstall Windows with this feature enabled)...

           

          More and more folks are running into this issue - and it isn't isolated to only Intel's boards. The problem is they cannot just go out and buy a new board (because this usually also means getting a new processor, new memory, etc.) and they do not have the funds to do so. I wish that the motherboard and (especially) the video card manufacturers would do a better job of explaining - on the box - what the requirements for using their products actually are...

            Thank you for the well-explained answer.  Yeah, I assumed it was BIOS related.  But the fact that the newer Maxwell-equipped EVGA GTX 960 FTW with its late UEFI BIOS worked w/o a hitch, led me to assume a re-badged 7000 series AMD gfx card would surely work as well.  Alas, it seems that is not the case.  I even tried my UEFI-BIOS GTX 750 Ti, and it worked too!  Oh well, looks like I stick with new Nvidia or old AMD cards for this board.

             

            Can you (or anyone) link me to a site that lists the various cards' BIOS;  UEFI, legacy or both?

              There is no such database, as i know, but there is a way to check exact BIOS file for images present in it:

               

              nvflash --pciblocks filename

               

              Example:

               

              >nvflash --pciblocks gm200.rom

              As you see, both cards have two images: legacy and UEFI.

               

              Great storage of card BIOSes is on http://www.techpowerup.com/vgabios/ , and with GPU-Z you can extract a BIOS file from exact videocard.

                Clutchc,

                 

                Just to be sure, since you didn't say and this information may be helpful to other folks:

                 

                1. Did the GTX 960 FTW and GTX 750 Ti would regardless of the UEFI setting (i.e. they still include legacy OpROM support) or did you have to enable UEFI before they would work?
                2. You are saying that, regardless of the UEFI setting, the R7-370 won't work, right?

                 

                I took a look at the specifications for a couple of the R7-370 boards offered by NewEgg. They all state that the interface is PCIe 3.0 x16, but do not say one way or the other whether it is backward compatible with boards supporting (only) PCIe 1.x and/or 2.x.

                  Hi again,

                  1) I am able to get a POST display at boot using the GTX 750 Ti and the GTX 960 with the UEFI setting enabled or disabled in BIOS.  (Surprisingly, I can boot to my Win7x64 installation in either mode)

                  2) That is correct.  Neither UEFI enabled or disabled in BIOS will allow a display at Boot.  Nor even move into a blind Win boot.  The machine doesn't seem to be able to complete POST.

                   

                  I build several a few PCs per year.  Both new and rebuilds.  I have yet to come across an older board that was not fully PCI Express backward-compatible with any cards I have tested.  Not saying there are none, just never came across any myself...yet.  PCI Express is suppose to be a backward-compatible interface.  Even an old PCIe 1.0 board has always recognize a later gen card for me.  But, since both the AMD and Nvidia cards I'm using are 3.0, that doesn't seem to be the issue, anyway.  The DP45SG recognizes the 3.0 Nvidia cards.  It appears to be something specific to the R7-370 BIOS that doesn't agree with this elderly Intel board.  I may grab an inexpensive R7-2xx card and experiment just to satisfy my curiousity.

                  But thank you for your followup.

                   

                  @ JFFulcrum

                  Thanks for that info and links.  Handy items.  I will do some research using that in the future.

                    This all depends upon whether a particular card requires PCIe 3.0. If they've removed support for legacy operation, you're pooched -- but I (also) think that this is not the case; I am leaning towards this being a BIOS issue. While the 4 Series board's BIOSs supported UEFI, there may be bugs, incompatibilities or missing features in an implementation that is this old...

                      It must be as you say; the Intel BIOS.  The card obviously doesn't require 3.0.  It worked just fine on my MSI G31TM-P31 motherboard.  And it was only PCIe Gen 1.0
