I'm having poor performance issues crossfire using an AMD A8-5600K/Sapphire
HD6670 1GB PCI-E card.
The System's specs are:
Sapphire HD 6670 1GB GDDR5 PCI-E Graphics Card
AMD A8 5600K Black Edition 3.6GHz
Gigabyte GA-F2A85XM-D3H A85X Socket FM2 Mainboard
Seagate 1TB Barracuda 3.5" SATA-III Hard Drive - 7200RPM 64MB Cache
Kingston 8GB (2x4GB) DDR3 1600MHz HyperX Genesis Memory
CIT 750W Power supply
Microsoft Windows 8 64-bit
I based my choice of hardware on online reviews and benchmarks results.
Crossfire is enabled according to the Vision Engine Control Centre and the
latest AMD drivers are installed. Windows is up to date. Otherwise all other
hardware and system settings are unmodified.
I thoroughly benchmarked the system with several synthetic tools and several
games prior to enabling crossfire. I then enabled crossfire and retested. The
results are :
Min fps 19.8
Min fps 16.1
Max fps 68.8 Max
As you can see, apart from the Unigine scores, every benchmark has improved
after enabling crossfire. (Although not as much as I was led to expect.)
With fps in games however, things are far from convincing.
Fraps Alan Wake
Fraps Far Cry 3
Fraps Aliens CM
As you can see, performance either drops or improves only minimally.
Is there anything anyone can recommend to help resolve these performance issues.
This system is only a week old and I am already beginning to regret putting it
together with these components.>>
