ATI crossfire configuration

Q: ATI crossfire configuration

Not that I will see any performance boost, or that I would be better off by just buying a higher end card, lets say just for the sake of discussion....If I installed two identical crossfire 'supported' graphics cards on a crossfire enabled motherboard, do I need a connector cable to couple the cards or will the motherboard recognize the setup and couple them for me? If a cable or jumper is needed where might I purchase one? Anyone know? The motherboard in question is an ASUS M2R32-MVP and the cards are ASUS EAH4670/DI/1GD3/A. I guess I just have too much time on my hands and would like to see if I can make it work. Any help again would be greatly appreciated!

Preferred Solution: ATI crossfire configuration

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Can Vista support more than 1 GPU driver? I am running Vista Ult 64. Looking to upgrade to Windows 7.

I previously had an Nvidia 8800GT as my primary graphics card and also had an 8500GT installed as well on my dual boot XP/Vista PC. They worked fine and the computer recognized both correclty on both OS's I think I didn't have any trouble b/c as I found it all 8 series cards use the same driver.

I bought a new primary GPU, a ATi Sapphire 4870 1GB Toxic. I am NOT trying to run SLI or Crossfire, I need availability for 3+ monitors. Can I have two completely different video drivers? I was under the impression NO, but a computer parts guy said I can install an Nvidia & ATi driver as long as I do not install the supplemental software.

I need to set up three user accounts on two computers the accounts on each computer is going to be monitored.
Each user will be assigned access for certain folder or files and certain applications, like internet explorer.
And all usb ports and dvd drive will be blocked. Only the admin will be allow to have full access.

So i need to do something that allow ( managers) to monitor employees activity on the system during working hours.

On one pc is windows xp pro on the other os windows 7 home premium.

Any idea how i can acomplish this task?

I.was thinking of group policy on both computers but on home premium there is not group policy.

Also the users will be using almost all the same programs and files just the with different information.

Thank you in advance.

But for Windows 7 Home Premium you will not have the
Local Security Policy so you may need to upgrade to Windows 7 Pro for that.

This is easier to control with a server like Windows Server 2003 or 2008.

I have an old P3 system that I let my son use for internet browsing, email, etc. It has been rock solid for 6+ years until lately and I think the issue of not booting properly is that the master CD-ROM gave up the ghost. And so I took that out hoping that is all it will take.

Here is my question (and I feel so much like a noob; I did try to google but I got nothing): Where do I place the tab to take it from slave to single configuration? As slave the tab was placed on the far left in the verticle position. Am I correct in that to make it singular I need to place it horizontally on the bottom two prongs center-right?

I hope I am making myself clear. This is an old system and it has been years since setting it up and I don't have my manuals anywhere. I couldn't even access Buslink's website.

Thanks for your help.

A:CD-RW Configuration - from slave to single configuration?

The jumper will fit on the pins, based on what is imprinted or embossed on the drive. It is usually very difficult to see... but if you use a flashlight or other device you can place at different angles, you can see how the jumper choices are stamped into the metal. Most often the center two are Slave, the right is Master, and the left is Cable Select.
I suggest you jumper it as master.
If it is a known brand, you can find a drawing on the website of the optical drive manufacturer.

Asus A8R32-MVP deluxe crossfire ready
2g Corsair
ATI Radeon x1950 512 crossfire edition
**new** Diamond x1950 XTX 512 crossfire ready

OK, so before the 2nd card, everything was peachy. After installing the 2nd card, I went into CCC to set it up, enabled crossfire from the bottom tab, ok good to go right? OK, well first thing I noticed is it would not let me run both monitors in crossfire mode, regardless of which port I plugged the 2nd monitor into. Could not find any info on either Diamond, or ATI's websites. Does anyone know if crossfire mode still supports dual monitors? They will both work as long as crossfire isn't enabled.

2007-04-19 19:36:50 - oblivion

OK, so this seems like a problem to me. Not much change at all between the 3. With a whole nother 512mb of video memory, I would expect to see at least a noticeable difference. What else was odd is that I got the highest FPS using both monitors with no Crossfire, which was wh... Read more

I have an Asus P5Q Delux in my HTPC case. Today I installed an ATI Radeon HD 4670 and I'm wondering if I should add a second HD 4670 in crossfire. The reason I'm "stuck" with this card is I can not fit a card longer than about 8.5" in my case (interference between video card and CD drive). Will it make much difference in video performance? Any issues?


You might want to push out the cd rom little bit which might not look cool but thats one way if you wanna considered using the same case and wanna install the graphic card. The other option is to remove the cd rom a get an external CD rom that should cost much. Else you need a New case and reassemble the entire thing.

Hello i recently purchased a custom pc online and im running on 2x Radeon (sapphire) HD 4650's and id like to run them as crossfire. I have crossfire enabled and all the software is suggesting that it is currently running and working but i dont see any performance to back it up. Ive disabled crossfire, played a game, and enabled, and i had the same FPS on each try. Is there a way to tell if its actually working?

A:ATI Crossfire

Play a game that actually supports Crossfire, maybe? Many games do not get any performance boost from dual graphics. That is why mid-range cards are a pointless thing to CF or SLi. Sell the cards and buy a 4830/9800GT and be happy with it.

Currently, there are these mainboards on the market:

ABit AT8
Asus A8R-MVP
MSI RD480 Neo2-FI

Which one should I use?

I heard that they stopped to sell the ABit AT8 because of problems, and that the A8R-MVP is having some VCore problems. Also, a couple of people with the DFI claim that they have lots of reboot problems.

I haven't found anything on the MSI...

A:CROSSFIRE, which one?

Being subjective, I would go for MSI. My last 3 mainboards have been MSI and they are awesome boards. The one that I have now it's a pretty old one, but it's extremely stable and didn't cause any problems in more than 2 years.

Hey guys,

I just bought a 2nd Gigabyte Radeon HD 4870 1GB Zalman card to run in crossfire with my current one.

I have the Gigabyte x58 UD5 board, so when I put them both in the 16x slots they are almost touching each other.

I am really keen to get them running together but not too sure about the heat factor. My PSU sits at the bottom of the case and with the cooler on the card, wont allow for the bottom PCIE slot(8X) slot to be used either .

Any suggestions, besides a motherboard change

A:To Crossfire or Not to Crossfire?

well the cards might produce a bit of heat inside the case w/o the reference cooler, i'm unfamiliar with the design of zalman's cooler for the 4870. it probably won't be too bad if you have decent enough airflow in there but without some kind of exhaust it could get a bit toasty. the 4870 isn't an ideal choice for aftermarket cooling, especially in a CF configuration but I think you'll be alright. if not you could always buy different coolers or apply some better thermal compound to each core.

...and on a side note i highly recommend ATI Tray Tools over CCC to enable/disable your CrossFire, it doesn't really matter but I ran into a couple problems in CCC before. with ATT it's been smooth sailing. just a suggestion...

I have a question, does crossfire work with win7. Because now if i use te CCC or even a ATI-driver for that sake performance goes down by about 20
% and video-card (asus EAH3870-magic) chrashes en reboots. Wath realy spoils gaming !!


A:Crossfire ?

Crossfire does work in Seven.

Download and install Driver Sweeper:
Guru3D - Driver Sweeper

1. Uninstall ATI Catalyst install manager in control panel>uninstall programs. It will ask you if want to restart.

2. Restart in safe mode and run Driver Sweeper as admin. Analyze and clean all ATI entries. (make sure you select ATI only)

3. Reboot normally and install the latest catlyst drivers. Reboot.

If crossfire is still causing crashes:

Repeat steps 1 and 2

After running Driver Sweeper in safe mode, shut down and physically remove one card. Go to step 3..

Once you've installed catalyst re-add the second card. Upon restart, the CCC should pop up and crossfireX should be enabled.

For those of you using ATI cards in a Crossfire setup, AMD/ATI has removed the normal Crossfire profiles from it's driver package recently. They now must be downloaded separately from the driver, and installed separately in order to optimize Crossfire performance in applications.

Those of you thinking that the new driver packages don't perform as well, and are using Crossfire, might want to check out:

Drivers & Support | GAME.AMD.COM

And download the profiles. It's under 500K in size.

ATI says it was done so that they can release the profiles more frequently, without having to rework the huge driver package when it isn't necessary.

I couldn't believe the difference in game performance after I installed them. I was thinking that I wasted my money on the second video card. Happily, I was wrong.

A:ATI Crossfire Tip

I have to ask:
Is the driver able to be installed normally yet? I know it was broken back when I bought a 5770... (for me anyways)

A:SLI = Crossfire?

No, they aren't the same. Crossfire only supports multiple ATI graphics cards and SLI only supports Nvidia cards. There are some motherboards that support both Crossfire and SLI but of those cards that support multiple graphics cards, most support only one or the other.

In your case you would have to buy two ATI cards and get rid of your Nvidia card.

Hi guys,

A freind asked me to help him build a budget gamer with him. He is a fan of AMD and ATI combos as apposed to Intel or Nivedia.

Hes not willing to spend past a certain point, so the cards cant excede $110 a piece ($220 for both cards is his budget.

Now, Im not to familiar with SLI/CrossFire set ups, and I personally am a Nivedia person, So Im haveing trouble with the hardware for this build. I think I got it down to 2 possible card sets. But want some advice as to which pair you would buy.

Set #1 = a pair of ASUS EAX1600PRO SILENT/TD/512M Radeon X1600PRO 512MB 128-bit GDDR2 PCI Express x16 Video Cards :
This card looks nice and its a silent fanless setup.

Set #2 = a pair of SAPPHIRE 100165L Radeon X1650PRO 512MB 128-bit GDDR2 PCI Express x16 Video Cards :
This card seams to have hiher core and memory.

Please follow the links and look at the specs for me, like I said, I'm not to noligable on ATI cards, and need to know which would make the better pair for the CrossFire rig

So I recently got a new build and I am quite happy with it but the fps on some games aren't quite what i'd like, so basically I want a bit of a boost kind of, or maybe a replacement if it comes to it. So I was wandering if I crossfired my R9 380 with another 380 would I see an improvement in games in general? If specific games, maybe games like CS:GO or Arma 3. If not then I may just try to get a good selling deal for my current GPU and get a better one

I'm running a GIGABYTE MA790X-DS4 Mobo and I have a Nvida 9500GT, The mobo has a ATI chipset & is setup for ATI's Crossfire, but I would like to know If I could run dual 9500GT's on this mobo or would I have to use ATI products? Is there any way of doing so safely? (I bought the VC about 2 months ago and the mobo about 1 month ago, I don't just want to throw a good VC away) Basically I would like to know if I can run SLI on a Crossfire mobo, and if so, How?

A:SLI and Crossfire?

you can run two 9500s as independent cards, but you will NOT be SLI enabled

so the answer is no im afraid, the only board currently capable of running both SLI & CFX is Skulltrail.

an upgrade is the only route for better performance

(geforce 9500gt 1gb)

this is for gaming/everyday stuff
cod4 , crysis , mercanaries 2...etc....



Hi Luke,

I am not sure about the ATI Crossfire range, but for the NVidia range it is preferable for both cards to be of the same specification.
Unfortunately, your choice of motherboard has only 1 PCI-E graphics slot, so is unsuitable for multiple graphics cards.

I'm planning to get a second POWERCOLOR AX3650 512MD2, but I think I lost the bridge from the first one I had. To make matters more confusing, I don't think the bridge even came with the first one, because I checked the contents of it online and it didn't say it came with a crossfire bridge. Also, I heard that for crossfire to work, it just has to be the same GPU, so is it possible for me to cross that card with a POWERCOLOR AX3650 1GBD2 ?

Manufacterer's website: http://www.powercolor.com/eng/products_speci.asp?ProductID=4056

The two seem the same in every way except for a memory difference.

A:What do I need for ATI crossfire?

There are two ways to link the cards for Crossfire I think; most new cards include the internal bridge. There is another type of bridge that has two DVI adapters to plug into each card which goes outside the case as opposed to linking the tabs inside. You could probably get both types off eBay or something if you don't get one with the second card.

Those two cards use the same exact GPU so they should work together. I'm not sure which one you should put as Master but I don't think the difference in memory would prevent them from working. I'm 90% sure that they would work in Crossfire, they use the same driver too.

You can get internal bridges here, but that seems a little pricey imo.

Hello all

I finally decided to build this system:

APEVIA X-Infinity Metal Case
-BFG GeForce 8800GTX OC2 Edition
- 2GB OCZ DDR2 PC2-6400 ATI Crossfire Dual Channel
-Seagate Barracuda 7200.10 750GB 7200 RPM 16MB Cache Sata II Hard Drive ST3500630AS
-OCZ GameXStream 850W SLI Power Supply
-P5KC Dual-channel DDR2 1066/800/667 MHz or DDR3 1333/1066/800
-Vantec Spectrum PCI Fan Card with Blue UV LED
Lite-On Super-Multi LH20A1H Light scribe DVD Burner - 20x DVD±R Burn

Now is there any conflict or mismatch between 8800GTX and P5KC motherboard, because the motherboard and the OCZ DDR2 are Crossfire ready when 8800GTX is SLI ready.
They both improve quality of the image? Or you have to have one or the other. No mixing them up. Do i really need Sli or Crossfire to improve for picture quality?

Thank you

Let me know your opinions.Click to expand...

Both work great performance wise but since NVIDIA's cards are somewhat more powerful the performance by using those cards will be boosted. It's a pretty expensive solution though and only if you are willing to give a lot of money it will provide results. For average money solutions both companies are equally good.

Also, you have to check if the motherboard's chipset support both SLI and Crossfire. For example some Intel chipsets only support crossfire.

I don't know about the ability of crossfire to combine different cards. I only know that certain onboard ATI/AMD cards can work in combination with standalone ATI/AMD cards via Crossfire, resulting in better performance and used as a cheap, but pretty powerful alternative.

When I bought all the stuff to create a crossfire machine.. I it would be a sinch...

So far I am fairly disapointed....

It tells me that my bridge interconnecter are not installed correctly, and I have tried every combination to connect them. and I havent read anything about compatability. whether my cards are compatable with my MSI K9A platnum crossfire edition.

it talks about a Crossfire Edition card and a crossfire ready card and external connecters.. nothing about internal connecters.

should I returne my crossfire motherboard and video cards and go with Nvidia Sli cards and an SLI motherboard..

can any one give me a hand with this?

I've been thinking about buying a second Radeon HD 4890 for my PC. Since I already have an ATI, going SLI would be expensive as I'd have to buy 2 graphics cards instead of one plus what would I do with my Radeon? So if I'm going multi-GPU, Crossfire is where I'm going. However, is it really worth it? Will installing a second graphics card make my desktop be able to run games like Garrys Mod any better? I'd like to be able to cause massive effects everywhere and not lag (explosions, crazy SWEPs, etc.)

CrossFire performance/compatibility is always a priority in new driver releases. So it should only be improving with every Driver/CrossFire Application Profile release.

(2x) Radeon HD 4890s would translate to NVIDIA GeForce GTX 470/480 performance levels.

Like I said, definitely worth it.

i want to build a computer runing SLI, i found a motherboard that i like and it said that this supports crossfire, now i like better Nvidia card and i want to get SLI can i run SLI on a Crossfire ready motherboard??? if not what motherboard will you recomend, i want to play all new games and i want the motherboard to support quadcores. is there also any good motherboard that can support phenoms and be SLI ready now that AMD bought ATI???

A:Crossfire and SLI

SLI is nvidia only, and Crossfire is ATI only.

For an SLI setup, look for a motherboard featuring the nVidia 680 or 780 chipsets. They give excellent gaming performance and are not crazy-expensive.

Also, please note that the two nVidia cards you use need to be identical. (ie: you can't match a 8800 GT with an 8800 GTX).

Hi guys, hope somebody can help
I just got another xfx 4890 and have been trying to crossfire it with my other xfx4890 but just keeps crashing and won't even boot up, i've tried the cards seperately and they both work and tried both slots with both cards in each and all seems fine on their own, i've tried 4 different crossfire ribbons. i tried uninstalling the drivers and it starts to boot then gets to just before my desktop and then it crashes and reboots immediately, no BSOD or error messages, i also tried in safe mode and once the 2nd card is enabled and restart it does the same and crashes and reboots.
i hope its something really simple that i have maybe forgot to do cuz i'm at my wits end

A:crossfire help

Even though you have a good PSU with plenty of watts....still sounds like a PSU problem...how old is this PSU?

Would I notice much performance boost if I were to crossfire an xfx ati radeo hd5850 and a Sapphire HD 5850 Xtreme is this possible and what performance boost could be expected many thanks!!


In theory 50%...in practice +50% to 0% depending on how well the game can scale between two cards....

I currently have an Msi r6970 lightning. I want to get another for crossfire. I can get the reference amd brand card for alot cheaper than another msi though.
Can these be used together in xfire?
I've only ever messed with dual gpu setup once with two pny gtx 550 ti's. Never tried mixing brands/speeds.

A:Crossfire Q?

Should be no problem.

AMD CrossFire

Dangerous advice follows: it may be possible to flash both cards with the same firmware, so that the drivers would see them as identical.

Which one is better, the SLI setup or the soon to be ATI Crossfire?

*Read a review that the x1800ct single handly beat out 2 Geforce 7800 GTX's in SLI??? Is that possible?


A:SLI Vs. Crossfire

I read a review on megagames, the guy had seriously overclocked his ATI X1800XT and it must have only just beat the nVidia ones, or it could have been a load of BS!

I have a single 7800GTX 256mb, with standard cooling and no overclock, i got 7530marks with my 3d Mark 2005 test. so i can't see how that review or article could be true anyway!

I would say ATI is better but I haven't seen much on it. I do know that SLI has improved drastically over the last few months since it was re-introduced by nVidia!

hey SF,

i have some questions about crossfire. i've searched on google but i didnt seem to find what i want(for the first question, for the others i just want to be sure ^^).

okay, onto the questions:
1. how will crossfire affect the heat, right now my single 5770 is 71 degrees on full load
2. will i be able to add a different GPU as crossfire (for example, a 6970) i know i will have to upgrade PSU too then.
3. if 2. is no, does the GPU have to be the same make/brand

thanks in advance,



1. The temps will go up a bit, but ss long as you have decent airflow to begin with it shouldn't be much of a concern.

2. Different, no. They have to be within the same GPU family. This shows which work with which,

3. No they don't have to from the same manufacturer. Also see #2.
