Hi guys,

Does anyone have any idea why one of my R9280x cards is listed as an 79XX series card instead of a R9280 card?

I currently have crossfire enabled and my 3dmark scores seem to indicate that crossfire is working. I just can't help but wonder whether the performance is affected by the system not being able to detect one of the cards as a R9280.

I've tried updating to the latest drivers but it doesn't change it.

Any help is much appreciated!

Thanks!

Do you have catalyst 13.11 installed?

The R9 280X is a rebadged HD 7970. It's not supposed to be that obvious, but it shouldn't matter. 7970s and 280Xs are confirmed to be fully Crossfire-compatible.

probably need newer drivers. as others have said, its the same card anyway, but i would be checking the card itself and the box to make sure you got what you were sold. are they identical cards from identical manufacturers?

Thanks for all the replies guys!

Yup, both are gigabyte cards. I have the latest 13.11 drivers installed.

Will this result in any significant performance and/or stability issue?

Thanks guys!

Thanks a bunch!

I decided to try installing the latest 13.11 beta drivers again and it seems to have fix the recognition issue - both cards are indicated as 280x.

Thanks once again!

On a side note, is it ok that one card is running PCIe 3.0 while the other is running PCIe 2.0? (I'm using an MSI b85 g43 gaming mobo with an i5 4570) Will this configuration in any way affect Crossfire/Overall performance? (Max res I use is 1920 x 1080)

i recommend reducing the pcie 3 card to pcie 2 speed if your bios allows it. the more even you get the performance between the cards, the less likely you will get micro-stutter.

Could I trouble you for a step-by-step guide to doing the above mentioned bios adjustment? Sorry, I'm a techno noob!

Thanks!

it's not necessary, see how it goes first, it might not be an issue. You would have to read through your motherboard manual or go into your bios and look for the option, not familiar with your motherboard.

The second card is on a PCIe 2.0 x4 connection, which is not optimal. No matter what, you will be losing a few percent performance because of it.

Yup, I just read through my mobo manual and I realised that I've got only 1 PCIe 3.0 slot. Should have done more research into the mobo before commiting to it (it came highly recommended on my local GPU site forum).

I know it's probably not advisable, but should I upgrade to a mobo that has at least 2x PCIe 3.0 to fully utilise my 2x GPUs?

Thanks!

It's not just PCIe 3.0. It's that it's a 4-lane connection. PCIe 3.0 gives twice as much bandwidth per lane as PCIe 2.0, but 16 lanes is 4 times as much as 4. Anyway, a PCIe 2.0 x8 link (or equivalent PCIe 3.0 x4) should be sufficient for optimal performance. But I'm not sure buying a new motherboard would be worth it. Give it a try on your current motherboard first.

Noted. Thanks Sakkura!

In the meantime, while I'm giving my current set-up a try, is there anything in particular I should monitor or keep an eye out for?

Oh and just for the sake of asking, what mobo would you recommend if the stars all aligned and Santa decided to coincidentally give me a new mobo for Christmas? Haha (I'm running an i5 4570)

Well, you could check the framerate or look out for any stuttering. But it's hard to measure accurately without special equipment.

Asrock Z87 Extreme3 is one of the cheapest boards that provides an x8 connection for each card in Crossfire.
