[NAME], ignore your referenced post as the root cause of the problem that OP was having was an Nvidia driver change that altered the default behavior of the Telsa card in question (and none of us read NVidia's documentation untill much later). Since your using GeForce card and GeForce driver, such issues as described in that post are not really relevant to you. And the reason i modded my card was that the T610 does not have a x16 PCIe slot and i provided this info as background but it is also not directly relevant to your issue. The best thing for you to do is to download and read "Dell Poweredge T620 Systems Owner's Manual", also known and "T620 HOM". Google should be able to provide a link to the dell download page... Anyway on page 28 & 29 of this document you will find the "Integrated device" BIOS screen for the T620, specifically page 29 shows "Embedded Video Controller" and a short description... What this document does not say is that you can not change the setting unless the system detects the card is actually inserted (well that's the case on the T610 and i expect it's the same on the T620). So, if you insert a video card into your x16 slot and if you can't change the BIOS setting above, then either the card is faulty or the slot is faulty or you installed the card into a slot connected to the second processor socket in a single processor system which may not be a supported configuration. Page 129 of T620 HOM states slot 5 through 7 can't be used unless two processors are installed. So if you installed the GPU in slot 5 and only have one CPU installed, this configuration won't work, try installing the GPU in slot 2.!! If you can't access the BIOS setting for Embedded Video Controller, then this needs to be sorted out BEFORE you can proceed further, no point in trying to install drivers into the OS for a card the BIOS can't see!!!  Oh, and if you do set the Embedded Video Controller to DISABLED but you still don't see any video output when you connect the monitor to the card, then you can always reset the BIOS back to default settings (which for Embedded Video Controller is ENABLED option) and reconnect your monitor back to the motherboard VGA connector. The system should work just as it did before (though you may have to go into BIOS and set those options you may have changed from their default values). How to set BIOS back to default setting is not well described in the T620 HOW but look at the NVRAM_CLR jumper shown on page 125 & 126 and you should see that setting the jumper to pins 1-3 will reset the BIOS to default on the next boot. Presumably after the reboot you shut down the system and move the jumper back to pins 3-5 !! Just got to love the Dell documentation :emotion-1: So go back to basics and tell us which slot you plugged your GeForce GTX card into and whether you can then access the Embedded Video Controller option within the Integrated Devices Screen in your T620 BIOS. And a list of the installed hardware may not go astray...
Hi, I just got a PowerEdge T620 and installed a GTX780Ti. I downloaded the latest driver for the card, and I am have BIOS 1.4.6 on the T620. I am in the middle of trying to update the BIOS, but I cannot figure it out?! I tried to create a DOS-Bootable USB stick with RUFUS, but I guess my USB stick doesn't allow that... Anyhow, what do I need to do, to get the video card to work?! I understand that I will NOT be able to use a monitor connected to the card, but I can live with that... I guess. I would be very happy if I could at least get the card to work?! The card is installed in the top slot and I hooked up the cables to it, that say GPU on them... What else do I need to do?! thanks, G  p.s. this is on Windows 7. I tried to update the cards's driver on Windows Server 2008R2 and got an error message?! However, the driver that came on the CD installed fine... (on Windows Server 2008R2).
T620's device manager recognizes GTX780Ti, but programs do not "see" the card?!
