Dell quietly released two new BIOS versions for the M14x, A07 and A08. Changes for A07 are: Link for A07 And for A08 it says: Link for A08 I'm not sure what the change of the SATA speed limit really means, maybe you can now get full SATA2 speed through the ODD, that would be great in case you use a caddy for a second hard drive. A08 seems to be simply a VBIOS update for the 555m. As always recently, Dell is pretty mean when it comes to information about the changes in the new BIOS revisions, these two points mentioned above are definitely important and I recommend to apply the update, but I also guess that there are some additional fixes and enhancements which aren't mentioned. I'm gonna take a look at both BIOS and see what I can do regarding the volt mod etc. Edit: Seems like A08 isn't up yet, it say file not found when I try to download it. Edit 2: There's absolutely no difference between the VBIOS in A08 and the VBIOS in the older versions... seems Dell messed up.

Hey guys, BIOS A07 for the r3 got just released. Changes are "Support 3D function of N12E-GTX2 & N12E-GS", which means 3d support for the Nvidia GTX 580m and 560m. The BIOS can be downloaded here, have fun flashing. Hope it improves the overall performance as well. Reports stated that A05 didn't perform very well. EDIT: Some more details about the update: - eSATA3 enhancements for the Kingston SSD eXtreme edition - timing adjustments for the ODDs (new manufacturer) - lot of overdue bugfixes
