I have recently bought myself a new computer setup and i am having issues with the gpu.
I am using the following:-
GA-Z87X-OC mobo
4770k i7 processor
2x8G of Corsair DDRIII RAM @ 1600
Silverstone 750w 100% modular gold power supply
Sapphire HD 7870 2GB OC GPU
BIOS version F3 with PCIe-1 set as first boot display (which is the slot where the card is)
Running Windows 7 Pro x64
At first i could not get the GPU to display at all, so i used onboard and installed my OS and everything. I then thought to check my device manager and have a look at the GPU and it was in the list, but it said widows found a problem with it and stopped it (error code 43.)
So i took it back to Umart where i bought it and they tested it. I worked just fine there. They stress tested and and it was all good.
I brought it back home and put it back in my comp and walla... it worked.
Showed up in device manager as working. All was good. Or so i thought...
After a couple of reboots i noticed the POST screen with the GIGABYTE Logo artifacting and the screen blinking with lines all over the screen.
And then after a few more boots i would have to restart the computer after i push the power button to get the display.
Now i am back to onboard graphics with the error 43 code for the not working GPU display again.
Now since i know that the GPU works in other systems i have to assume it is a compatibility issue between it and the Mobo...
I have emailed GIGABYTE Technical Support and it looks like it might be a while for a reply, so in the mean time if anyone has any info they can give to fix this asap any help would be much appreciated.
Cheers
EDIT:- Also on a side note i noticed when my RAM is set to auto its goes to 1333 when i have 1600 RAM installed. Its not so much of an issue because i manually set it to 1600, but i thought it would pick that up automatically.
