[Official] AMD R9 295X2 Owners Club - Page 800

post #7991 of 9142
Hey everyone. Forgive me if I'm violating any policies but I could really use some help.

I recently picked up an R9 295x2 on ebay for my new build PC. I was a little leary about ebay, but the seller had outstanding reviews over several years so I took a chance.

I plug it in and everything seems fine on bootup. Except my PC isn't recognizing the card as a dual GPU. I got the latest catalyst beta drivers, but when I go to the main menu under "Gaming", the AMD Crossfire option doesn't even appear. I got GPU-z and again, only recognizes a single gpu.

I'm worried I got a bad card, but is it known to have a single core die, and yet the other gpu core runs fine with no problems at all? I gotta think there's some driver or bios setting causing the issue, but I'm stumped.

I have a new Gigabyte GA-Z170X-Gaming 3 motherboard. I've looked around the bios, but nothing jumping out at me that would cause anything to cause crossfire not to work.


Any ideas anyone could come up with would be greatly appreciated.

Axiumone - you're the man, I'll check that tonight. The picture is super helpful.

I was surprised by a few shipping charges once ($7 for a $5 order, ?). I have a ton of spare screws from them because I initially just kept buying from them for small quantity need. I gave ebay a shot after folks recommended that over spending more @ mcmastercarr. I love their site and they pretty much have everything, but it can get expensive for something that is usually inexpensive and low quantity.

I use ebay for small quantities (usually less then 100) and I end up paying a few dollars for a US shippers. If you don't mind a wait, the chinese sellers will sell you large quantities for a great price. I will admit, the mcmaster screws have endured better then ebay ones tbh (that's because i change hardware, or used to, quite often). When it came time to mate a backplate to a different make block, ebay screws were cheap and readily available. There's a few Vegas sellers that sell at pretty good prices and ship fast (well, for me in SoCal).


For the blocks, they usually come in w/ M3 or M2.5. DD (rip) used to use a very small size which is very surprising on how piggish their blocks were. Best to check the instructions for both and then you can figure how to mate plates with different make blocks. I've mated EVGA, EK, XSPC, custom (diy) plates with different blocks from ek, xspc, danger den, koolance, hk, ac, etc.. Its not too challenging but you can make it work. For those looking for active cooling on a backplate w/ block, you run into issues but remember the plate will do very little cooling compared to the block. I would recommend it for air coolers though. The EVGA plates are notorious for this (as well as some stock oem plates). EK plates tend to be very straight forward and usually use four or six outer perimeter holes or screws on the blocks. They usually use counter-sunk head screws (m3 or m2.5). Again, best to find the instructions for both and that will give you an idea of how they can be paired (though having both on hand will help even further).

I just got an XSPC backplate from NCIX, supplies are really thin and EKs are unfindable. I'll let you know how it goes.

Crossfire on these cards is by default. You can't turn it off unless you use a custom profile for a game/program. If you want to verify it is there us something like GPU-z. Have that running and do some bench tests that support crossfire and check the load for each GPU.

As I said, i loaded up GPU-z and it only shows a single GPU and crossfire being disabled. Not sure what could be going on. I click the "Lookup" button on GPU-z and it brings me right to the R9 295x2 page. So it is correctly identifying it as an r9 295x2. Just with no crossfire and a single GPU

Use DDU: http://www.guru3d.com/files-details/display-driver-uninstaller-download.html

Uninstall your current drivers then install the most current WHQL driver (15.7.1 iirc)

I've had this issue on my 390x, I'm willing to bet if you plugged the card into another PCIe slot it will work fine smile.gif

Tried this and still no-go. (Well, haven;t tried a diferent slot, but Ii want to use my 16x one). I did use the DDU, uninstalled everything, then re-installed the 15.7.1 drivers. Same thing. GPU-z still shows single GPU with crossfire disabled.

Do you have a second system or a friend that can help you with this? Just pop it in their system and see what happens. Or if you have a frys or micro center near by, pick up a cheap z170 board and see what happens. My suspicion lies with the card. Even with no drivers my system can see the cores. How long ago did you buy the card (ebay buyer protection)?

Sounds like you're talking about mixing a backplate and a waterblock from two different manufacturers. I was just asking about putting a backplate on the stock cooler for aesthetics. Sounds like it should work, provided I find the right screws (which I would have thought come with the backplate, but I'll find out).

New question: I find my VRM fan makes a clicking noise, only sometimes, any ideas how to fix that?

Np, and the same goes for fitting a different backplate to the stock 295x2. Though I would caution as the stock reference backplate does cool and most waterblock backplates are purely looks. You may have a hard time finding screws for the stock cooler that can reach but its possible all in all.

for the clicking, it maybe a fan issue if the cable suggestion auxiome suggested does not work. I had occasional clicking on psu fans.

Less than a week ago. So I can certainly explore that route if I got a bum card. I would not be happy to say the least. Seems strange the card seems to work fine though. No overheating, no glitches, anything like that.

Bought it less than a week ago. I do have another board. Its not a Z170, its my old PC but it should still work in case there's something up with the bios. I guess thats my next step.

Try different slot. Some motherboards have a problem that some slots can't accept dual gpu cards.
