If you do not have the expected graphic performance (low fps with low graphic settings, 3DMark03 much less than ~8800, 3DMark05 much less than ~3700) on a notebook M3438 or M4438, you probably still have the old Video-BIOS 5.41.02.39.49 installed.
Some more details and the link to the new VBIOS 5.41.02.39.60 can be found here
