I have a really big conundrum. ![Confused :confused: :confused:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
I have a computer which I have built that has been running fine with the following specs.
AMD FX8350 CPU Overclocked to 5GHz
Asus Crosshair V Foruma Motherboard with the latest Bios Revision
16 Gigabytes of G Skill Ripjaw Memory.
2 Samsung 840 Evo's
OCZ 1250 watt power supply.
Dual R290 XFX core edition video cards in cross fire mode.
Koolance Exos V2r2 watercooling system with additional 140 mm Radiater in push pull configuration with a Koolance 5 1/4 bay reservoir and pump combo.
I recently installed my 2nd R290 into my computer and it was running flawlessly with the core heat sinks and fan. I was getting about 11000+ benchmarks in 3D Mark Firestrike with both cards stock.
I bought 2 Koolance water blocks that are made for the R290s and installed them onto the video cards.
The computer boots up and displays Bios Post on the first card though the HDMI port and the windows splash screen displays fine. when the splash screen is about to go into the login screen the primary display goes black.
The 2nd video card gets video output through the hdmi port and windows 8.1 recognizes both display adapters and is in enable in crossfire.
The video cards with cpu are cooled fine and run at a peak temperature of 50 degree's Celsius under full load.
It was working fine initially until I over clocked the video cards and this is when this started. I have since placed the cards back into stock settings and the problem is still occuring.
in 3d mark I am benching of 12800 on the firestrike test with a 1100 clock with 1400Mhz Memory.
GPUz shows both cards and statistics fine with the exception of the fan speed as there is no fans to report on the video cards anymore.
I have re seated both video cards. Tried the 13.11 Beta AMD Drivers, the 13.12 Video drivers and the same symptoms happen. The primary display will only show the bios post screen and windows 8.1 loading screen in when the drivers are installed.
When I uninstall the drivers using the Driver Delete Utility and install the basic windows drivers it will display on the primary display.
I have tried a fresh install of windows 8.1 and it able to be replicated.
I am going to try installing windows 8 and try testing each card separately to see if it will be corrected.
Has anyone else experienced this before? Am I missing something with the troubleshooting? Any Help will be greatly appreciated.![Confused :confused: :confused:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
What is odd is that the set up is unable to detect additional displays connected in this setup with the AMD Drivers. I am leaning towards a driver issue but I don't want to rule out a possible windows 8.1, o/s or hardware issue.
