There are issues for this driver especially for certain model such as HP G62 and Compaq presario CQ32.
Most people will get the latest catalyst driver instead of using the driver provided by the laptop/computer manufacture.
Latest Catalyst (on feb 2012) : 12.12 win 7/vista 32 and 64-bit : Download
Generally here is the most stable catalyst driver version i found so far:
Ati catalyst version 11.2 : Download(64-bit)
ATI Catalyst Version 10.12 : Download(32/64-bit)
Other version that reported work:
Catalyst Version 11.3 (64-bit)
ATI Catalyst 10.11
1. Compaq/HP Model:
The driver provided by compaq/HP is sp50231.exe
But direct installation normally don;t give a max resolution (case for HP G62) so you need to upgrade the BIOS version to F28-F29, install Intel HD 3000 (swicthable graphic) and turn off power play in CCC. ( not recommended to use this driver )
2. Acer Model
VGA_AMD_8.741.1.5000_W7x86W7x64_A.zip : Download
Support : Radeon HD 5470 Radeon HD 6370M
This driver only applicable for acer (4738G etc) and Acer didn't allow to use with non-acer product.
