aRTee Posted August 3, 2003 Report Share Posted August 3, 2003 bvc, I think some SiS systems have only one chip in their chipset, so technically just a chip not a set... and since all interconnects are within the same die, they can have a much higher bandwidth... Apart from that, I don't really know. Don't worry about it though, the lower of the two numbers is the more important one. Quote Link to comment Share on other sites More sharing options...
Germ Posted August 3, 2003 Report Share Posted August 3, 2003 Germ, how did you turn accoustical mgnt off? I figured setting it to 254 -M254 was basically turning it off. :? Maxtor has a utility called amset. You can d/l it at maxtor.com There are 3 settings that Maxtor HDDs support for acoustical management. quiet, fast, and off. hdparm says: Recommended acoustic management value: 192, current value: 0 Quote Link to comment Share on other sites More sharing options...
Guest GorGor Posted August 8, 2003 Report Share Posted August 8, 2003 since you are boasting On my 4 year hd I get 80 and 20 Mbps shucks. aaahh, don't forget to include it in your init scripts so the speeds will always be there, assuming you turn off your computer.

bvc Posted August 8, 2003 Report Share Posted August 8, 2003 Actually, open /etc/rd.d/rc.sysinit and search for hdparm to find the right way to initialize at boot via /etc/sysconfig/harddisk. If you have more than one hd you'll need (example) harddiskhda harddiskhdb harddiskhdc...and so on. Don't recall if its harddisk or harddisks so read rc.sysinit.

Germ Posted August 8, 2003 Report Share Posted August 8, 2003 /etc/rc.d/harddisks is the default file you get when installing hdparm. Then copy it as harddiskhda, etc. to tweak individual disks. You can add hdparm settings to /etc/rc.d/rc.sysinit Quote Link to comment Share on other sites More sharing options...
Germ Posted August 11, 2003 Report Share Posted August 11, 2003 OK, I'm amazed. I'm using this string: -d1 -X69 -u1 -c3 -m16 -A1 -a32 -B255 -M254 Added "idebus=100" to append in lilo.conf and here's what I got: [root@grendel root]# hdparm -Tt /dev/hda /dev/hda: Timing buffer-cache reads: 956 MB in 2.00 seconds = 478.00 MB/sec Timing buffered disk reads: 106 MB in 3.02 seconds = 35.10 MB/sec I thought that can't be right so tried again and got: /dev/hda: Timing buffer-cache reads: 1020 MB in 2.00 seconds = 510.00 MB/sec Timing buffered disk reads: 106 MB in 3.02 seconds = 35.10 MB/sec /germ Quote Link to comment Share on other sites More sharing options...

Germ Posted August 12, 2003 Report Share Posted August 12, 2003 :D I got the increase after adding idebus=100 to lilo. I had it set in BIOS, but my HDD kept dropping back to udma3 until I edited lilo. Now it hangs at udma5. Quote Link to comment Share on other sites More sharing options...
bvc Posted August 12, 2003 Report Share Posted August 12, 2003 Now it hangs at udma5.as in stays, or sticks? I already had idebus=133 in grub, so something else, or a combo is doing it for me. Quote Link to comment Share on other sites More sharing options...
Germ Posted August 13, 2003 Report Share Posted August 13, 2003 It keeps the setting. :wink: Quote Link to comment Share on other sites More sharing options...

Gowator Posted October 1, 2003 Report Share Posted October 1, 2003 If hdb is faster (I presume with the 8MB cache) then you are probably dragging the two down by slaving it. You can try fiddling with the filesystems at detail level. Spin speed etc and try and get them to actually sync better. Obviously depends on the fs .....
