What do you mean "after 5.13"...
That is the ATI driver number (ATI Catalyst Control Center). In other words you should have ATI 6.4 installed to be up to date.
Just some info so you understand the number from ATI
6= The 6 is for the year 2006
4= The 4th month of the year the driver was put out for down load.
So the new driver for "this month" is 6.4
Last year was the 1st year they went to 13 (no 13th month) because ATI had a major bug in the ATI drivers, so they didn't want to wait untill the 6.1 driver to repair it so we got a driver of 5.13 last year in December, meaning there was 2 drivers for that month. lol ok ATI school is over.
ok, i dont need it then. thx
No as Bone said you don't need it. BUT what is nice about having them is if you have fans that turn at a good RPM, the driver will slow them down when the CPU is NOT under load (that is IF you have a CnQ option in bios). Like right now I have my CPU clocked to 2.5 and now my CPU setting is at nice slow 1.08 because I am just on the net and not loading the CPU with work.
