Hi,
I recently bought a second 6990 to make 6990 Quadfire and i'm having issues. Compared with other systems (http://www.youtube.com/watch?v=imT6-CkOYZM). While he had 1566 as a score our rig came out with approx 1100, our fps was also less than 40. I've also been noticing that since i put quadfire on I wasn't getting much of a performance increase, if any. In metro 2033 I was looking at peoples rigs for example, some guy had 3x6950's and a i5 processor. He was also running eyefinity on a higher resolution and was getting approx double the FPS that we achieve.
We have ran some benchmarks on our system.
On 3D vantage 11 we got:
Score: 8804 with 1 6990
Graphic: 9782
Physics: 6953
Combined: 6521
Test 1 FPS: 41
Test 2 FPS: 50
Test 3 FPS: 60
Test 4 FPS: 29
Physics: 22
Combined: 30
Score: 13464 with 2 6990's
Graphics: 17675
Physics: 9757
Combined: 5995
Test 1 FPS: 59
Test 2 FPS: 101
Test 3 FPS: 120
Test 4 FPS: 59
Physics: 30
Combined: 27
The card settings where the same on both but the CPU had been overclocked from 3.4ghz to 4.5ghz
On Haven benchmark 2.5 we got:
Score: 2026 with 1 6990
FPS: 80
Min FPS: 12
Max FPS: 186
Score: 3844 with 2 6990
FPS: 152.6
Min FPS: 23.9
Max FPS: 328
The card settings where the same on both but the CPU had been overclocked from 3.4ghz to 4.5ghz.
From the benchmark results it shows that we have almost doubled our performance score, but in games we do not see this. The reason we bought another 6990 was so we could play games in eyefinity smoothly, but it's not playable in it's current state. We are also aware that our second 6990 is running on a x8 PCIe but we where informed that it would only cause a minimal performance decrease.
My system spec is as follows:
I7 2600K Sandy Bridge OC to 4.5ghz
HD 6990 Quadfire (HD 6990X2)
Corsair AX1200 PSU
Asrock Z68 Extreme4 mobo
G-Skill Ripjaws X DDR3 1600Mhz 16GB
Corsair H50 Cpu cooler
3x 23" monitors using resolution 5760x1200
