I have a very strange problem with my GA-P67A-UD7 motherboard. After six days of perfect running, my PC failed to turn back on when resuming from sleep mode. giving me one long and two short beeps. After troubleshooting, I changed the GPU to a radeon 5850, and it worked fine. naturally, I RMA'd the GTX 580, thinking that this was at fault.
I had my GTX 580 GPU sent back to me - but proved to be fine when the company I bought it from tested it.
Once I had the GPU back, I tried the 580 again in PCIx16 slot 1 on the motherboard, but, alas, I still received one long and two short beeps, indicating that the monitor or GPU were faulty (According to page 114 of the Gigabyte GA-P67A-UD7 manual). While the GPU was away to be test by the company I bought it from, a Radeon 5850 was fitted into the PCI x 16 slot, and it has been working fine.
I then tried the 580 GPU in another PC, and it worked. (An older S775 motherboard)
I then tried the GPU in PCIx16 number 2 slot on the UD7 mainboard. I get the same beep error. I even tried different PSU's and different connectors (the ones that come with the GPU, in case the user doesn't have the required PCI-E cables with their PSU), but the same result.
I then tried the 580 in the PCI-Ex8 slot on the UD7 motherboard, and it works on that. It does not work in either of the PCI-Ex16 slots.
It is very strange that an ATI Radeon 5850 works fine in the PCI-Ex16 slot, but the GTX580 absolutely refuses to - makes no sense to me! (The PC boots fine, as I can hear the W7 start-up tune - but no picture - I have tried with 2 different monitors and two different cables)
I changed the BIOS from version 7A to the 'Formal release' 7, last week, while my 580 was at Scan being tested – just to make sure all was as up to date as it can be.
As mentioned, the 580 worked fine for six days after putting the components together. Then, when the PC went into sleep mode, the problem started. The PC is working, but there is no signal going to the monitor. I only get the warning beeps if the card is in the x16 slots in the UD7 mainboard.
The GTX 580 in a PC with a E8600 Core2Duo and Gigabyte GA-EP43T-UD3L based PC - but not in a motherboard costing three times as much!
I did also take out the soundcard and PCI wireless adaptor - just to be sure. (I had to anyway, as I tested the 580 in both x16 and x8 slots)
I hadn't overclocked the GTX 580 once during the six days it worked in the x16 slot - just a mild overclock on the 2600k - and even then, as soon as I heard of the SB problem, I put everything back to stock, just in case. Strangely, the GPU seemed to die an hour after I read about the SB problem - it does make you slightly paranoid! Especially when you have just spent the best part of £2.5k on PC components that are meant to last me about three years for CAD and rendering work!”
Now, obviously, the GPU seems fine, and the motherboard accepts other GPU’s in the x16 PCI-E slot. It is just the GTX 580 that will not work.
Is this unique?
I recorded (and my son hosted on You Tube)switching the PC on with the GPU in the first x16 slot, and then in the x8 slot. You can hear the fault beeps for the first, and a single beep for the second film;
