settings . have just run sisoft sandra benchmark and apparently the only thing that isnt set up the best it can be is my hard drive , have looked in bios but cant see where to change them . K7S5A mobo and diamond max plus 8:
SMART is not enabled. For safety/reliability it is best for it to be enabled. SMART monitors critical drive parameters and is able to warn you if the drive is about to fail so that you can back up the data and replace the drive. It has minimal performance impact that is offset by the security.
Acoustic Management enabled. While this reduces the noise the drive generates, the performance is almost always impaired. Most of the time fans generate more noise than the drive itself. If the drive does generate a lot of noise, it may be faulty. You could also consider swapping the drive for another model that generates less noise.
Current transfer mode not optimal, i.e. not highest supported. This affects drive performance. If the controller is also capable of the highest supported transfer mode, there is no reason not to use it.
Look on the Advanced Setup page of the BOS for SMART enabling (see p24 of Version3.1b of the user manual).
The Acoustic management setting will not appear in the BIOS
Transfer rate - well you should be using the highset rate, of course - you may already be, and they've got it wrong. The main thing you can do is check that you've got an 80-wire IDE cable if you have a drive UDMA66 or higher.
Whilst I agree with the general sentiments about Sandra - it doesn't necessarily get everything wrong all the time.
