295x2 will not work with my ASUS Crosshair V Formula-Z motherboard

[southpark11235]

I have an XFX 295x2 and I cannot get it to display anything with my ASUS Crosshair V Formula-Z motherboard. I am hoping someone on here has same GPU and motherboard combination so they can tell me if it is a compatibility issue or if something is defective.
The first time I put the 295x2 in my motherboard, I was able to get it to show the bios just fine. However after I save changes to the bios (it does not matter whether or not I change anything), it will not display anything on the monitors. No POST, no bios, no Windows, nothing. If I clear CMOS, I can get it to display the bios again just fine, but again the second I save changes, it will not display anything. The motherboard will work fine with all three of my old 5870’s in crossfire or on their own, and with a junkie little GeForce 210 I have lying around. I can get into Windows and play games etc. without issue. It is just the 295x2 that will not work with my motherboard. I tested the 295x2 with an ASUS M5A99FX motherboard I have in another computer waiting to be delivered to someone (mildly amusing story behind that computer if anyone is bored) and it works just fine. I am able to save changes to the bios and get into Windows with the ASUS M5A99FX. With the 295x2 and Crosshair V combo I have tried switching PCI express slots, with and without the Molex connector on the motherboard that supplies more power to the PCI express slot plug-in, made sure I was using the latest bois, triple checking/unplugging and replugging the power connectors for the GPU and only using one of my two monitors connected with a DVI cable and a mini display port to HDMI adapter. None of that change any of the symptoms. I think that is everything I have tried. It has been a long troubleshooting process, so I may be forgetting something.
Here are my computer’s specs
CPU: AMD FX-9370
Motherboard: ASUS Crosshair V Formula-Z
GPU: XFX 295x2
RAM: G.SKILL Ripjaws X DDR3 2133 16Gb(4GBx4)
PSU: Corsair AX1200
OS: Windows 7 64-bit

I actually have a very similar setup. I have the same MOBO and I have the Sapphire R9 295x2. It has been running without any problems since I installed it. When I received my GPU from newegg, I first re-installed my windows 7 so I can start with a clean slate. Then I went through installing all the other programs as well. Since mine works, it shouldn't be any compatibility issue. I will try and answer any other questions you may have, but their are other people on this forum who have way more technical knowledge than I do.

I just had an idea. Could you please tell me what is the version number of BIOS you are run on your MB?

My MB version # is 2101.

Are you changing the secure boot or CSM by chance? I know you said that you don't have to make any changes to start this cycle of no output, but very curious for your response. I have 2 290x, which is what you have essentially, and if I start with a clean BIOS and change the CSM to Disabled, I can no longer boot into BIOS and just get a black screen from that point on. I have to clear to get back in BIOS or to POST. Let me know.

I just tried messing with CSM and secure boot, but they did not have any effect. During one of my boots I did get a random message saying that the UEFI driver was not compatible with the VGA. I was not able to reproduce this message. The CSM sets the PCI slots to legacy by default and changing them to UEFI did nothing.

I am currently using the xfx R9 295x2 with a rosewill lightning 1300w psu. since looking at your specifications, you might be looking at not enough power going though your system (if additional hardware is connected). There is a minimum 12 volt rail requirement for this gpu and your cpu (and additional components) may be draining it. The way I have my system configured is 8 Pin cpu MB cable connected (NOT the MB 4 pin as well) and the 4 pin molex gpu power connected as well. My mother board is bios version 2101 but I also was using version 1201 beforehand. When I first installed this gpu, I had my cpu at stock speed (yours is factory Overclocked/volted), Ram not overclocked (yours is OC), and I unplugged the extra HD's. hope this helps. Check my current PC Specs if this helps.

AD4RKW4R,

Are you also using the ASUS Crosshair V Formula-Z Motherboard.? Because I have the following in my new build and I am having nothing but HELLish performance problems with this Video Card as well. See my system build below but I am getting extremely poor performance out of games like Call of Duty Advanced Warfare (30 - 50 FPS with High 30's being the average and that with the Video options set to Optimal. If I try and pump up Video options details the game becomes unplayable (like slow motion). The Beginning in game Movie is really choppy and audio cuts in and out. I see screen tearing effects nd also this game under advanced video Options only shows your video card and Dedicated RAM, and this games reports a single R9 200 with 4056 MG dedicated RAM (But Windows 7 and Catalyst CM both see the 2 Cards in X-fire) Batman Arkham City Benchmark I got Max of 88 FPS, Average of 34 FPS and minimum of 12 FPS. (and all with V-SYNC disabled for both games). I just sent the card to XFX and they could not find anything wrong and are blaming something else in my system as a bottle neck- BUT WHAT???. Everything in this system is AMD so should all play nicely - this is ludicrous and I feel like I got ripped off with this Card. Anybody else having really poor performance issues with this video card and Motherboard combo???? Please help or offer suggestions because now I may have to buy a whole new Motherboard, Processor and Memory just to accommodate this card which is nothing more than a +700$ door stop now. ;-(

if you using the corsair axi psu use corsair link to set your psu on 40amps all rails then take the check out of all rails to make it a single rail that will make sure your getting enouph power to the cards
