I just built my computer today and I'm still not used to all the new technology. The 5670's say they are crossfire ready and neither of the video cards have bridge. Apparently they do not need them but the catalyst control center wont let me set up crossfire saying the cards are not bridged. What am I doing wrong?

More about : sapphire radeon hd5670 crossfirex

I think whether or not they need to be bridged depends on the motherboard but I could be wrong.

The documentation for the motherboard pretty much said that it depends on the video card. I noticed that catalyst is reading the second vid card but is saying it is disabled

The bridge is normally packaged with the Motherboard.

some model of HD5670 doesnt need a bridge to CrossFire them .. im using Sapphire HD5670 512MB, it doesnt have a bridge there. I did some research and it stated that the HD5670 doenst consume a lot of power, hence it doesnt need a bridge to do the job.. im not sure whether the bridge is associated with supplying power for CrossFire-ing.
Hope this will help you.

Your right Keropi. This particular model does not need the bridge for the reason you stated. That's why I don't understand why catalyst is saying I need to bridge the cards in order to enable crossfire. I've made sure the drivers are up to date as well as the catalyst software. I'm wondering if it my power supply may be to weak. Here are the specs for this system.

600 Watt Power supply
LGA 1156 Gigabyte Mobo
Core i7 860 Processor
8 GB Dual Channel Ram
500 GB SATA Hard Drive
2 Sapphire Radeon HD5670 512 MB Video Cards

I was told that the power supply should take care of everything since the Core i7 processors and the video cards are both low profile but maybe not?

If the PSU isn't powerful enough the system simply wont run or will be unstable and shut down when more power is needed than can be supplied. It's not going to remove the option to crossfire from the drivers.
That said if that PSU is of sketchy quality that system may be too much for it. What brand is it?

That's what I was figuring. The system runs just fine and actually handles pretty well off just the one video card but I would obviously like to have them both running. I bought the case and the power supply off ebay. Here is the link.

PSUs that come with cases are almost uniformly sketchy so you are pushing it a bit with that PSU. If the system is running stably I guess it's ok for now but don't be surprised if it gives out on you before too long.

That's what the folks at the computer store told me when I purchased all my parts (besides the case, HDD, and DVD Burner). They said they would suggest at least 700 watts but that 600 might do it. I plan to get a new PSU eventually but if the system is running stably currently, then I would assume that this is not causing my crossfire problems?

I thumbed through the bios to see if there were any settings that applied to crossfire but I could not find anything. Am I missing something there possibly?

The 5670 doesn't need the bridge, however the mobo must support PCI-E device to PCI-E device communication, I think most LGA1156 mobos made by Gigabyte do however.

Yes. This one does according to the manual. I know both video cards are ok. I have plugged the monitor into both cards and they both work fine as well as swapping them out on the Mobo. I just cant figure it out.



This is also what I'm seeing in the information center which says the second card is disabled.

Have you downloaded and installed the latest drivers form the Sapphire website? I'm thinking it is possible that since Sapphire's cards do not have the crossfire bridge on the card that it is enabled through their and only their version of the drivers.

I know for a fact that ATI says if you have an integrated card in a laptop that you get the latest drivers form the laptops manufacturers website and not theirs (ATI's) website as each integrated card comes with slightly different features that are only supported by that manufacture. Hope this helps.

Well, I just tried to update all the drivers from Sapphire as well as tried to update my drivers for my MOBO as well. Still no luck. I may see if I can roll back the drivers to their original state when I first put the computer together and then try to update. I will let you know the results.

Why would you ever xfire 5670s? Why not just buy a faster single GPU card? Xfire should be regulated to the high end.

Prove that. Also, more heat, more power usage, more PCIe slots, doesn't work well with games that don't scale well to xfire, etc etc.

Have you tried BIOS settings? Does your MoBo has jumpers for activating the second PCIe x16?

Cheers!

Look at the WAW chart, at the bottom, on the first link.

February 23, 2010 8:28:24 PM

The WAW chart helps PsychoSaysDie in that the 5870 and crossfire 5770s perform the same, so that the advantage lies with the cheaper 5770s.

However that HAWX chart hirts PsychoSaysDie in that the 5870 blows past the crossfire 5770s, thus justifying the price difference.

More reviews will be needed as these reviews just contract each other, to get an average, not just individual games.

Crossfired HD5770s will have average frame rates a bit higher than the HD5870 and minimum frame rates a bit lower(because of the lower memory bandwidth.)
A good article comparing the 2 setups can be found here;
http://www.xbitlabs.com/articles/video/display/radeon-h...
I would recommend OCing an HD5850 instead of either.

Well the 5770 xfire might be a little cheaper than a 5870 at the same price point, but it uses more power, generates more heat, uses twice sa many pcie slots, requires a xfire mobo, only gets to 5870 speed when running at 16x/16x not a 8x 8x, and 16x 16x rewuires a high end AM3 board, or a even more expensive x58 board, and is only good at games that use xfire well.

Are you sure about the 8x thing? Where did you read that?

No, that article shows that you lose 4% when crossfiring HD5870s; a card twice as powerful as the HD5770. The more powerful the card the more bandwidth it needs through the PCIe slot so you can't generalize those results. Furthermore even if it were the same for crossfired HD5770s saying that a 4% loss in performance means it is no longer on par with an HD5870 is silly.
There are certainly advantages to a single card (which is why I recommended OCing an HD5850 instead) but in this conversation general performance is not one of them.

The 5870 is probably the only single-GPU card that will use x16 PCI-E 2.0 (5850 might be the other).

Mid range cards like the 4890 and the gtx 285 need it for best prefomance to. Also, when i call the GTX 285 midrange, i mean by power, not by price lol. It's high end by price.

Do you have a link to support that? If true I would guess that means the HD5970 is being crippled by any current PCIe slot.

Crippled is strong. Hindred is more like it. Any good GPU will feel the effects of 8x. Anyhting faster than a 9800GX2 starts to lose out.

A 4890 is a single GPU with all communication inside the chip.
The 4850 CF actually needs the PCI-E slot to communicate, that's a HUGE difference.
Price does crap.

No, a 4890 ($200) runs fine on a 8x PCI-E 2.0 slot.
Almost all mobo's have a x16 PCI-E slot.
You don't need a good mobo at all to run even a 5850.

February 27, 2010 12:30:20 PM

Right, but my point was that in order to run Xfire well, you need a highish end board, wich means that Xfire is only a good option for those building computers at the high end. Also, the orginal discusion was that Xfire low end (by prefomance) cards like the 5770 is a good idea, but you can only do it well with a high end mobo, and if you want to spend money on a nice-ish mobo, then why buy low/mid-low end cards?

Sorry its taken so long to reply. It looked like the forum died for a bit but then I checked my e-mail and saw there were reply's again. I'm still having the same problem and Sapphire can't figure it out either cuz they used the same mobo as me to test the configuration and it worked for them. To respond to an earlier question, the mobo is a GIGABYTE GA-P55-UD4P

Any news, I am at the same point you are or were, I have contacted Sapphire and they are looking into it :( 

By -the-way anyone want to buy a pair of super cool video cards?

Nope. I gave up after searching around forever. The one card in itself runs most of the games I play quite well. I run Star Trek Online at absolute max settings and get a FPS at around 26 i believe. Not the as smooth as id like but still pretty dang good. Only games like crysis does it have slow framerate at max settings. So my other card is just sitting there. Im about to update the drivers from 10.3 to 10.4. Hoping maybe AMD may have finally gotten around to fixing the problem as seems a lot of folk with the same config are having the same problems. I know they can crossfire cuz sapphire tested the config and was lucky enough that the testing rig they were using had the exact same mobo as me and it worked fine for them.
