I dont know if somebody noticed it but AMD issued a crossfire compatibility chart few days ago

http://sites.amd.com/us/game/technology/Pages/crossfirex.aspx

As most AMD users knows about AMD's flexibility when it comes to crossfire on multi GPU's





it appears that the R9 series and R7 series are compatible only same series.

Meaning, according to them you cannot crossfire 290x and 290, you cannot crossfire 295X2 and 290X.

I know there is alot of forum/users that successfully crossfire 295X2 and 290X.

I kept reading about latency issues with crossfired 290X and 290 wherein the fast card will have to wait for the slow card to render thereby adding some latency. Although, mostly visible to benchmarks but not so much thru gaming.

Reason why I am sharing this is that seeing prices of used 290X on ebay, I have come to an idea about buying 290X to quadfire with my current three 290's. I know alot of reactions from most of you guys about latency issues with PLX and bottleneck from my 4770K. I am fully aware of that. But I am considering as well upgrading to Haswell-E or Broadwell-E or whichever. Atleast GPU's are prepared.

:toast:

Anyway, what do you think guys about the compatibility chart? AMD is clearly abandoning the "flexible crossfiring". Believe they ditch that idea so they can concentrate more in the issues might encounter somewhere down the road. Maybe ..... just guessing :banghead:

This is odd, i know may people that mix 290*s / 280*s and works great!

Also AMD were pretty big on the 'hybrid' whatever its called crossfire!

Hi

"*AMD"
On occasions I feel a sence of "*blind leading the blind" [Meaning here] as the current driver still supports the 7xxx, 6xxx & 5xxx serise yet the graph in the OP only shows R9 & R7.

What's is realy funny is the description on the web site that still clearly compares all results to a HD 5970 setup [countless times I have given feedback to AMD with regard to the latter]

AMD should have:
Included the previous chart; as an archive until the 7xxx, 6xxx & 5xxx Serise are made Legacy by driver redundancy.

They should have included of course the old AMD crossfire chart.

Thanks @d1nky Yes that is what they called it "hybrid" crossfire. I know also that you can crossfire R9 280x with 7970s (ghz or the plain 7970) and I know somebody also have successfully crossfire 280x with HD 7950. There was no intensive review yet.

I suspect that AMD dont want that to find out about issues users might encounter. It is doable but AMD dont have official statement about that. although from old chart, you can crossfire 79xx series .

We all know 79xx series and R9 280/X are all Tahiti chips

I just go with the rule that if the cards have the same base core they will work together.
R9 295X2 R9 290X and R9 290 are all compatible
HD7990 HD7970 HD7950 HD7870XT R9 280X R9 280 are all compatible but a bit of headache when you mix HD with R9
HD7870 HD7850 R9 270X R9 270 R7 265 are all compatible
The lower cards follow similar rules but you really shouldn't be CFing those os I won't go over them.
Also when you run to different cards in CrossFire it's called CrossFireX. Hybrid CrossFire is when you CrossFire an APU with a GPU and as far as I know it's pretty broken.

I thought an APU with a GPU was known as "Dual Graphics"? Or are you refering to when a "non-supported" card (i.e. one not suggested by AMD to be crossfired with that APU) is crossfired with an APU.

It's a bloody mess. The original APU's had Hybrid Crossfire with the 6670, and the latest APU's have dual graphics.
I think that's right. Could be entirely wrong. It could be that notebook APU + GPU is dual graphics, and desktop APU + GPU is Hybrid Crossfire.


Dual graphics is the new phrase for Hybrid CrossfireX since 2012

At least with SLI there's the general rule that if they're not the same GPU, then you can't SLI them.

Bit wrong on that regard. It's not the 5770 that can be crossfired, but the 5830, as 5770's core is different. plus the bus width as well.

Never knew that about the 58xx series. I'm soon to retire (sell) a 5870 so that's a good selling point!

True. this was from the previous gen of AMD GPU's but seems that AMD is abandoning them now. They might have difficulties and AMD couldnt guarantee the CrossfireX or Hybrid Xfire or whatever it is called especially with the R9 290's onwards GPU's

Crossfirer'ing a 7950 with a 280X like i did, may cause high frametimes or frametime spikes, up to 30ms depends on the game. I noticed this 2 days ago while is was configuring dragon age inquisition for hours like a madman is was trying to figure out what is causing this frametime spikes.
To fix this, the 79X0 card needs to be flashed with a 280X vbios, version 15.040 and up. I also flashed my GB 280X from v15.039 to v15.043 with an msi bios.

This advice should come with a Warning
[Note: Flashing vga cards without ensuring the PCB layouts, memory modules and outputs are identical can render the vga card as BRICKED]


For future reference; should include details: Make, Model, SKU and Vbios Version for all vga cards [do not assume readers on this forum know]

Note: I spend most of my time at TPU assisting with bricked cards

It can render a bricked card for sure, but even a totally different PCB card will take a flash the odd time but the card won't work but can be brought back to life if one knows what they're doing ;)

People that don't know how to flash, or have a back up plan shouldn't flash period, end of discussion.

To the op, I run a 290X and a 290 and actually have zero issues with studdering. Both are MSI cards and now I have the same V2 models. When I was dealing with RMA they sent a v1 card and it stuttered like mad, but even testing other v1 cards its clear the 2 cards were completely different.. Same memory, bit the v1's wouldn't clock very well but 2 of the same cards with the same layout work extremely well together.

I got all excited for a minute. Id love to try crossfiring my 5850 and 5770.

Crossfired 5770 and 5750 before and was a bit disapointed with the results and have always considered a single gpu to be a better solution.

For me the 5850 works better than 5770 /5750 combo.

one issue that i experienced when using 2 CF bridges on 2 card is, lags and that double/triple amount of vram is used. strange thing is most pictures that you see online have 2 CF bridges

I have a question that i see Sort of answered (to my understanding) in the previous posts, but can someone with Experience answer two questions.

#1 Can i Xfire My existing 7870Ghz with a r9 270X? to my understanding it seems like I can...but i wanna ask b4 i buy.
#2 Do i require an External Xfire bridge(or 2) to pair these two cards?
#3 Should i just forget My 7870Ghz, and NOT buy a r9270X, and instead go with a single card with more balls? 970/390 for example?

thanks in advance.

1: Yes
2: Yes
3: Eh, yea I would agree that a single more powerful card might be a better option but it depends on the price.

1) look at the previous post
2) look at the previous post
3) It really depends on your screen's resolution. If above 1080P, CF needs at least 3GB ram to each card in order not to bottleneck. If up to 1080P, 2GB GPUs are marginal for the heaviest games and plenty for most. At 1080P, 270X in CF copete with 290X and 970 in optimised games or a bit below in others. Only a few games are terrible now in CF and most of them do not need it as they are too light anyway so you can disable the 2nd GPU when you play those. From a financial point of view, anyone owning a 270X or 7970 is strongly suggested to CF it as power consumption is great too for their age and power in CF.

Okay I seen already but I want to double check before doing so as I'm building a computer and over time will upgade the parts on it but right now I'm low budget. The question I have is, Will a amd a10 7860 work with a r7 260x and later with an r9 270 or 270x? If not what CPU can I get budget wise to work with the R 260x for the time being and then upgrade to the R9 270 or 270x?

Thank you so much for answering the question if you can.

R7 260x might be a bit too powerful to crossfire with that CPU - Most folks would recommend a r7 240 or 250

Bit wrong on that regard. It's not the 5770 that can be crossfired, but the 5830, as 5770's core is different. plus the bus width as well.

I found many forums writing about 5870 eyefinity 2gb is compatible with 5770 radeon 1 gb, can someone clarify it?
