Specs:
HIS IceQx Radeon HD 6850 (x2)
AMD Phenom II 1075 X6 @ 3.0 (still using factory settings)
16 GB Gskill RAM 1333
GIGABYTE GA-890GPA-UD3H ATX AMD Motherboard
Ultra LSP750 750-Watt Power Supply
(x2) 500 GB, 7200 RPM HDD in RAID0 array
I was originally running a single 6850 with no problems. I recently decided to go with a Crossfire configuration. After installing the second card, my games looked very good and held a very steady FPS at first, but there was a problem. After about 5-10 minutes of gaming I would start to get FPS drops. My FPS would spike down from 60 to 20-30 and this would become more frequent (at most every 2-3 seconds) if I kept playing which made the gameplay appear choppy. This is happening in GPU intensive games like "Crysis 2" and in fairly non-GPU intensive games like "Orcs Must die". Games are technically "playable" but not enjoyable.
Here is what I have tried so far:
- disable Crossfire - no improvement
- Lowered graphics settings in games - no improvement
- I thought this might be a temperature issue. GPU #1 would reach temperatures of about 85 - 90 (Celsius) on full load and GPU #2 would reach mid 70's at max. I installed another case fan which took the temperatures down by about 3
- Instead of just re-installing drivers, I decided to re-format my HDD and re-install the OS (I like to do this whenever I add new internal hardware)
- removed GPU #2 and went back to my original configuration with GPU #1 only. Removed AMD driver and CAP, Driver sweeper, re-installed driver and CAP. ISSUE PERSISTED !!??!?
- used GPU-Z with only one card and temperature is maxing out at 88 degrees. Still running a bit hot imo.
At this point I am very open to suggestions. It seemed like running the GPUs in Crossfire is what caused my issue so I'm baffled as to why I'm still seeing this problem after completely removing GPU #2. Tonight I am going to try swapping the GPUs to see if one performs better than the other. If that doesn't solve anything, I will start looking at the RAM and PSU. I'm not sure what else to try. Does anyone have any suggestions?
