Hello, Tek Syndicate geniuses. I need your assistance. It seems my GTX 780 Lightning Edition card will not display; however, if left alone, the Windows 7 boot chime does occur. It is also important to note that I cannot even see the POST screen when the system powers on.
I have tried the following techniques: +Disable on board video +boot with only one stick of RAM +Unplugging all drives +Resetting CMOS +The power supply works. I have tested all 4 PCI-e cables in the working AMD card.
I can only assume either the card is bad or the PSU is not supplying enough power to the card. However, another fellow told me that the PSU is more than enough for my GPU. I really want to believe that the PSU is the culprit. Someone please shed some light on this situation.
Terrible psu - low amperage quad rail design. Regardless of the matter. 780's especially those cherry picked Lightning cards want a good strong power supply - single 12v rail w/ >48 amps. Something like this >> http://pcpartpicker.com/part/xfx-power-supply-pro750wp1750snlb9
Are you certain the 780 works? ie. tested in another machine?
correct monitor input source?
BIOS up to date? There could be a known bug that was fixed. After all the board is quite old. ...and this is on the assumption that just the 1 gpu is being run in the system.
It is really strange. I believe that the card is not recognized: even when the card is in slot and power cables are plugged in the motherboard will still boot with onboard video(if I enable it, anyway. Other times I have it disabled.) Does that mean that the motherboard is actually not reading the GPU? I feel like the card is working fine; the seller of the card assured me that it worked right before he shipped it. Therefore, it makes me feel like there is something really rare or strange going on. Do you think a bios update might fix the issue?
Okay, so get this! The motherboard was the culprit: for some reason the motherboard would not read the GPU. However, once I put the GPU into another board it worked. I am having one minor issue, however. The current system is as follows: AMD Phenom II X4 965 BE 4GB DDR2 RAM(suspect this is the cause of the issue) GTX 780 Lightning Edition The issue here is simple: I cannot get above 30 FPS on The Elder Scrolls Online, and after examining GPU usage it only goes up to 56% usage. However, it should be known that the ram maxes out at like 3.75 GB and the CPU sticks at 75%-85% usage, too. I assume that my CPU and RAM are bottlenecking my GPU at the moment? This hardware setup is temporary!
How does an Intel i5 2500k, MSI MPower Z77 motherboard, and 8GB DDR3 at 1600mhz sound? I am waiting for the motherboard to come in and the system will be ready.
It is all strange, but I have my new intel motherboard coming in soon. Therefore, I will just deal with the bottlenecks for the next few days. Thank you for the help, however. I currently have the card running on a different motherboard, so I am mostly happy.
