I changed mine from write back to write through and now my 70 is >really moving!!! > Write-back forces a simultaneous write to memory with every write to cache, so there's a ram access delay at every write. Write-through writes to the cache but only writes to real memory if the space in the cache is required for something else, or the system shuts down, or it's told to. So it's usually quicker. (actually, that feels the wrong way round, but it's early in the morning) I wrote a long screed on what all the bios switches do which should be in the archive somewhere and may be helpful. _________________________________________________________________ MSN Photos is the easiest way to share and print your photos: http://photos.msn.com/support/worldwide.aspx ************************************************************** http://libretto.basiclink.com - Libretto mailing list http://www.silverace.com/libretto/ - Archives -------TO UNSUBSCRIBE------- Reply to any of the list messages.
