Hi I've had this computer for a while now and haven't been able to get crossfireX working properly. when i run a benchmark the primary card shows like between 96-99% activity in Catalyst control center and the slave card is showing 0% activity, 0˚C Temp, 20% Fan speed and the GPU and Memory clock rates at 000MHz attachments show what i mean(GPU1.png = Primary Card) I switched cards to check that both are working properly and they are crossfireX just isnt working so i was wondering how i get crossfireX working My Computer Intel Core i5 750 2.66 GH Processor 8MB L3 Cache GIGABYTE P55-UD3 Intel P55 Chipset 8GB DDR3-1333 Memory Dual Channel 1000GB Samsung 7200rpm SATA2 Hard Drive Two ATI Sapphire HD5770 running in CrossfireX Thermaltake V9 Gaming Tower Case, 700W PSU Windows 7 Ultimate 64bit Graphics Software Driver Packaging Version - 8.732-100504a-099996C-ATI Catalyst Version - 10.5 2D Driver Version - 8.01.01.1030 Direct3D Version - 8.14.10.0753 OpenGL Version - 6.14.10.9836 Catalyst Control Center Version - 2010.0504.2152.37420 if u need any aditional driver info ask me and ill find it for you
Check my mail thread for more information on how to check whether crossfirex setup is correct or not. [Saphire toxic 5870 2GB CrossfireX scaling issue] Some questions: 1. How have you connected the two cards ? 2. Does your motherboard PCI Express slots are configured correctly in the BIOS? (none is disabled ?) 3. What does GPUZ shows in crossfirex field ? 4. Use MSI Kombuster Multi gpu version and try loading both cards. 5. Try running with only one card which is showing 0 gpu clock and 0 mem clock. FYI: In 10.5 I found a weird issue, when both cards are connected, just uncheck the CrossfireX option in CCC, and enable it again, baam!! The display color is dull. So I went back to 10.4.
Make sure the crossfire bridge is installed. Make sure crossfire is enabled Make sure catalyst AI is set to standard or advanced (and disable is not checked) Disable ULPS via registry.
1 by a single crossfire connector 2 i cant find PCI options in bios 3 enabled 4 when i use MSI Kombuster and do a benchmark it uses both gpu's(they show 90% usage) but when i benchmark with another program it only uses 1 gpu 5 done that card works fine
i did two benchmarks on PerformanceTest (64-bit), one with crossfirex on and one with crossfirex off the one with crossfirex on got slightly lower results (by like 1fps)
the second gpu is showing 157MHz core clock and 300MHz Memory Clock now but still no increase in activity when using anything except MSI Kombuster
Cat 10.5 disabled my Crossfire in Anno 1404. Only GPU2 is working, GPU1 is completly DEAD. So from my side you should go with 10.4 and redo everything again as 10.5 S.U.C.K.S harduke2:.
