I have a sata 3 hard drive and in my BIOS wen I go into my sata option you can set everythig.

then it gets downn to the 32 BIT option and you can have it enabled or disabled.

Now I think I know that when you had IDE hard drives you set it to 32 Bit because the drives talked in 32 BIT.

But does SATA 3 hard drive talk in 32 Bit or 64 Bit???WELL it depends on your mother BOARD and CPU are they 32 bit or 64 bit you need to find that out.I believe that SETTING is for IDE hard drives so no need to worry about it

MatMy motherboard is an ECS

Model
A780GM A

Serial Number
K61110E83803609
My CPU is AMD Athalone 64

How do I know if my Motherboard is 64 Bit??
I doubt that board supports either SATA3 and or 64Bit,Has SATA 3 even been released as a manufactured product for retail consumption yet?

I think the standard was just set up this summer wasn't it?Yes the SATA drives are SATA 3 and my CPU is AM2 SocetThe SATA 3 standard was approved in late May but I don't see a lot of SATA 3 drives on the market.According to This Article from a pretty reputable site SATA3 won't start showing up on MBoards til early next year....He probably means SATA 3-Gbit/sec, not VERSION 3 of the standard.
