thanks for your responses and your effort to help me with the performance problem. I meanwhile also contacted Gigabyte support because I suspected the combination of the Z68 motherboard with the ivy bridge GPU as the reason for the problem. The replicated by hardware setup and got a Furmark score of 274 for the 1080p preset with the driver provided by Gigabyte (220.127.116.11.2618). According to this website, this score is reasonable:
I followed their suggestion and ask for a replacement of the CPU. With the new CPU, I did a installation from scratch and used the same drivers as they did. The Furmark score of 73 is still far below theirs but this may be partly due to the slower RAM I use. [furmark.gif]
But this does not explain the poor overall performance of the GPU:
- The Passmark 3D should be around 622 according to
but is 160 [passmark.gif]
Interestingly, GPU-Z reports low GPU usage and standard core clock for the first 3 of the 4 test. Any idea why?
- In the SiSoft Sandra benchmark, the shader performance is next to nothing compared to similar builds (same board, but sandy bridge CPU).
- Cinebench 11.5 reports:
OpenGL Score 0.96 FPS
CPU 5.51 Points (this one is OK)
- 3DMark 11 Vantage reports an Error
and a really bad score of just 1
with the hint that the graphics driver was not accepted.
I ask them to check this with their setup. I'm curious whether they'll do much better…
Meanwhile, any suggestions from you are also welcome.
Something is terribly wrong. 1 point in 3dmark Vantage lol. The second game bench refused to run, something is really wrong. It can't be the driver. GPUz reports a vbios version 2117 which looks old. All GPUz screens with HD4000 I have seen had a vbios version 2124 or higher. The date of this vbios version reported from GPUz says 05/16/2011. So maybe you running an old Bios. What Bios do you have installed? According to Gigabyte you need at least version F11.
I was eventually able to solve the problem. As Yups suggested, installing the U1h UEFI bios did the trick. Even though this bios seems still to be beta, I did not have any issue with it yet. The system runs stable and all at once performance is as expected: between 270 and 280 points in Furmark 1080p. Assassins Creed II now runs in full details at 108ßp without problems. Its like a totally different system.
So thanks a lot to everybody for the help!
