Configure more than one graphics card in parallel may seem "simple", but carries some problems for many fans around the world becomes a real headache.
The world of computing and especially the dedicated high performance is within the branch of hardware, one of the most demanding user. PCs and their Windows operating systems have grown exponentially in power, devastating power that is capable console. The PS4 and Xbox "720" future already exceeded by many models midrange graphics cards on the market today, even before they come out. This increase in power has also led to increased complexity when you can configure our equipment.
I'll try to help you with some tips to hone your CrossFire and CrossFireX so you have your graphics always ready.
Problem Solving:
1) Drivers:
They are the graphics so air to breathe for us. Low-level control functions necessary to operate our game with proper performance. When using more than one graphics chip or even just one, is necessary if we have problems installing resort to a "clean" Drivers. I tell myself what has always worked best for me:
Installing "clean" Drivers:
We often have problems in PC gaming Subjects of drivers, which then often we blame hardware issues erróneamente.Si have configuration problems, unexpected exits to desktop, please try to give you some tips to let them resolved.
Steps to perform on Windows for troubleshooting and AMD CrossFireX:
1) Uninstall Catalyst Application Profiles.
2) Uninstall Catalyst Control Center.
3) Uninstall software you have additional AMD (AMD OpenCL Streaming or similar).
4) If you have AfterBurner or similar, desintálalos too.
5) If you already have Windows 7 SP1 or if you have Windows 8, install the latest Driver Sweeper last http://phyxion.net/Driver-Sweeper/Driver-Sweeper/
6) Install the latest CCleaner http://www.filehippo.com/es/download_ccleaner
6.1) [option if you have more than one monitor] off monitors and leaves only one for now. Physically disconnect, not just turn them off.
7) Start mode to "fail safe" in Windows 7 or 8.
8) Run Driver Sweeper with optional AMD / ATI.
9) Restart again after the changes and removal of software by the Driver Sweeper and restarts in Safe mode.
10) starts in normal mode.
10.1) [optional] * ATI * .SYS searches your hard drive, if you appear to hang on DriverSweeper files, these are backing the program does. If you appear hanging from Windows files, that are residues ATI driver that can remove (at least remaining in the recycle bin and verifies that are truly ATI).
11) Reboot and start in Safe Mode again. This time, used only CCleaner deletes all temporary and "truffled" remaining in the registry.
12) After cleaning CCleaner, still in Safe Mode, go to the Windows Control Panel and under "Device Manager" uninstalls the basic VGA drivers that come by default.
13) When you restart in normal mode, you will install the VGA drivers before you removed. Let installed (although some mistake nothing happens). Once you see that are installed restarted.
14) In normal mode now with all clean installs the 11.4 preview. Restart.
15) Install the latest CAP.
16) Install LadyBug -> http://developer.amd.com/samples/dem...timedemos.aspx
17) Go to the installation folder LadyBug and tweak the Sushi.ini to put vSync = t (or true ... is to bring the asset vSync within the ini).
18) checks Afterburner GPU usage while running the demo (if stuttering, extends the "hardware poll interval" da 3,000 milliseconds), NO and NO sconces OC no make any cooling profile.
If after implementation of technological demo of DX11, you see that the load GPU is doing and temperatures, "air", do not exceed 85 ° (or are at least 75 °), you have the CrossFire in perfect condition. If you have a single graph, also the temperatures are those that have indicated.
2) Proper Placement Of Graphics Cards:
When riding a CrossFire and CrossFireX is ESSENTIAL ventilation. If we media with air venting means, it is essential that the separation between graphic is wide enough to allow the graphical fans located at the top not "absorb" the subsequent graphic.
Often it is plugged suecede airflow or because the primary graphics card "stuck" is high or because we wiring that interrupts the movement of air or simply because we have an excess of dust on the fans. Long time controlled before a performance issue that is not due to temperature.
To detect performance problems due to temperature:
1) Lower monitoring tool and Overclocking MSI Afterburner.
2) Run the game suffered slowdowns.
3) Leave Afterburner running behind, make the update and refresh data is not very high (or will occur suttering because of the constant readings Afterburner).
4) Fire up the game and passing through the area that produces more load or stress on your graph.
5) Note the fan noise if at certain times it becomes too high, you have a heat problem (which may result from excessive ambient temperature or air flow problems inside the PC).
6) Exit the game and check the graph of Afterburner. If you see that peaks where temperatures exceed 90 ° and coincides with the core clock speed and memory drops sharply, it means that you have a temperature problem.
If you detect this situation, please find a way to reposition the graphic properly for a no air cover to the other or see if there is another component that may be interfering with proper ventilation. Sometimes certain motherboards do not serve to maintain within more than one or two graphics, verify that the PCB plate is large enough to allow clearance between the PCIe ports where they will go the cards.
3) Problems Suttering:
If after installing the drivers correctly and have monitored the temperatures Stuttering occurs, do not worry, there are certain occasions where it is unavoidable:
The so-called "Micro-stuttering" is an effect inherent to the current dual technology, triple or quad, both in its form by CrossfireX as SLI on NVidia case, which produces an effect of "no flow" on the screen when Real-time rendering a 3D scene, either in a game or on a bench.
It is "visible" to the eyes, but not for benchs Pulling "frame buffer" to determine that a frame has "gone" screen (hence the benchs reported almost the same amount of fps, despite viewed small stoppages). What happens is that under certain conditions, the rate of sustained images of sync and gives the impression that everything was "slower".
Usually occurs when:
Games without CrossFire profile or CrossFireX.
Filtered excessive extreme resolutions, depending on the graphics engine (AA8 to X, AF16, 1920x1200 and above). These filters can "eat" the ram of the graph, leaving no resources to the nucleus to pass textures. Try not to overdo the amount of anti-aliasing effects you use, gradually reduce them to see if the stuttering disappears.
Sometimes, there's bottleneck of the processor or ram and can affect the outcome final.Hacer OC the processor can help solve the problem slightly, but not usually necessary.
How to fix:
Updating Drivers.
Updating Direct X from Microsoft website.
Updating the games with the latest patches.
Watching that there will be actually another problem (excessive temperature in the cores or memory).
By increasing processor frequency (within reasonable limits), many problems of this kind are resolved.
One card at a speed and another to a different gives clear stuttering problems. Watch the Catalyst Control Center OverDrive GPU. It is you say, sometimes wear a watch to wear and what not all GPUs. Check your GPUs are running at the same speed.
Update drivers or conflicts with sound card.
Try turning VSYNC and if possible Triple Buffer.
Here are the top 3 tips I can give you to solve problems that often affect almost always at a setting of 2, 3 or 4 parallel graphs. If the topic interests you, I will continue expanding it.
