Thanks for you quick answer. I tried build 126.96.36.19952. (Any idea why this one is not provided by intel directly?) Unfortunately, it's not much better. Furmark says 113points (the hd 3000 had around 1500) and the cinebench score is 0.9.
ETU's GPU stress test fails again after 10s for this driver version. It also reports a constant rate of 653MHz for the GPU. I guess, that's the bug you mentioned. So this might be the issue but how can I fix it?
Furmark 1.10.1 720p= 437 points/7 fps avg
With the same driver I get a 3x better result. Can you log to file the GPU frequency with gpu-z while running Furmark? On my system the HD4000 clocks with 1150 Mhz while running Furmark. Your Furmark result is way too slow for some reason.
Try reinstalling the driver, first uninstalling the old one. Such performance differences are beyond clocking issues. Even if its running at 350MHz, that's only 3x difference in performance at maximum. Some part of the installation must be seriously wrong with your system. It's like drivers are not being used at all.
Run some benchmarks to see its running properly at least. Memory bandwidth, CPU clocks, whatever it may be.
Here are the geekbench scores for the system:
Win7 64 (32 bit benchmark)
Mac OSX 10.7.4 (32 bit benchmark)
Mac OSX 10.7.4 (64 bit benchmark)
On OSX, the results are significantly better but I think the Win7 score is still okay.
There is no official driver for the HD4000 under Mac OSX (it will be included in the next update), so there is no hardware acceleration and thus I cannot test OpenGL performance yet.
So the problem seems to be related only to graphics.
I have 2 theories:
a) it is the driver.
So far I have tested these without succes (I always uninstalled the previous driver)
- 188.8.131.52.2618 (provided by gigabyte, the only one where the ETU GPU stress test does not fail)
For the last one Furmark 1.10.1 1080p score is 113 (1fps) - thats the best so far.
GPU-Z tells me the core clock went up to 1150Hz so its not a clocking problem.
What puzzles me is that the load only goes up to 50 percent.
Any ideas what else to try?
b) it is the board.
As I told, the board has a sandy bridge chipset.
Gigabyte says, it supports Ivy Bridge processor, but maybe it does not support the on-chip GPU properly.
I have contacted there support to check this but have not got any answer yet.
Has anybody here some experience with Ivy Bridge graphics on z68 chipsets?
im an old intel user since pentium 133 till now intel 3570k ! ( just experienced 3 years amd garbage phenomenon ) !
now ! i got a problem ! while gaming system get shuting down then rework and comes up ! ( hard reset i think )
also im one the nvidia members ! and explain my problem in vn forums ! but no answer !
i just let intel identify my pc and give me this core ( 0120 1012 ) !
explore my pc!
ok ! the questions !
how i can test intel hd 4000 igpu in 3dmark ? when i got gtx580 dedicated card ?
why gpu-z shows 666mhz clock for intel hd 4000 ? no 1150 !!!!!!!!
when i run marsbenchmark and choose cpu for physx proccess in nvidia control panel , after 10 sec runing marsbenchmark system shuting down ( all fans and led and everything turn of ) then turning on and comeback to os !
its means cpu cant handle physx ???
and im sure about cpu overheating and gpu !
is it conflict between igpu and dedicated graphic card ?
is it about igu not compatible with those games ! ( battlefield3 - saintrow third and randomly in others ) !
