I have just setup my crossfire with an "ASUS hd7870 Direct CU II" and an "MSI hd7870 O.C. Edition".
Asus is the primary and Msi is the secondary card in my crossfire configuration.
After the setup, i had a closer look to the values with GPU-Z. Here below what i got, there are some strange results.
--- Results of ASUS (everything is normal) ;
--- Results of MSI (we have some troubles with the Bus Width and the Bandwidth values) ;
--- Sensors of ASUS (ASUS is the primary card but the GPU Core Clock and the GPU Memory Clock values are very low) ;
--- Sensors of MSI (Some values are missing but rest is normal somehow) ;
As you may notice, the most worrisome detail is the difference of the "Bus Width" and the "Bandwidth" between 2 cards. And my primary card, ASUS has a 1100 mHz of GPU Core Clock and 1250 mHz of GPU memory clock. These values are shown on the graphics card results page of the GPU-Z. However on the second page, Sensors, GPU Core Clock is shown as 300 mHz and GPU memory clock is as 150 Mhz ?!
After taking these results, i made some research and discovered something like ULPS. Most of the users have recommended to disable it so i did it. After disabling the ULPS, i got a tiny performance increase. On the other hand The values on the MSI results page got corrected as well. Now the program shows the "Bus Width" as 256 bit and the "Bandwidth" as 153 GB/s. But still, i cant get the correct values of ASUS...
EDIT : The results are taken during a heavy load on cards.
Before thinking of the reasons, i need to clarify that ;
- My mobo bios is up to date,
- Im using the final stable catalyst drivers (v13.12),
- My OS is up to date,
- And im using the final version of GPU-Z.
Below is my full system configuration ;
CPU : AMD FX X8 8350
MoBo : ASUS M5A99FX PRO R2.0 (with 4 16x PCI-e slots)
Memory : CORSAIR 8GB (2X4GB) VENGEANCE
GPU : ASUS HD 7870 DIRECTCU II + MSI HD 7870 O.C.
HDD : WD 1TB CAVIAR BLACK
Case : CORSAIR CARBIDE SERIES 200R
PSU : OCZ MODXSTREAM PRO 700 W
CPU Cooler : COOLER MASTER HYPER 212 EVO
OS : Win7 SP1 x64
So, considering the details and scenario, what are your opinions ? Is there something wrong with me or this is the way it is ?
What else recommendation you would give ? Should i be sad or cheer up ?
Thanks in advance...
