speed issues with barton 2800+ /w 1.5gb dual channel memory & dual SATA drives
I'm attempting to dual boot SuSE 9.0 and winxp on my fastest pc I use for windows and gaming so I can slowly migrate to linux but I'm having problems with the hardware. It is faster in many ways than this Tbird 1400 machine I run linux on but is running much slower. My first issue is with the chipset drivers. I got the latest NForce binary rpm build for SuSE 9.0 and install it


#rpm -ivh --replacepkgs NVIDIA_nforce-1.0-0261.suse90.i586.rpm

Does this mean it didn't install properly? I'm assuming the chipset driver needs to be updated and that's why it's so slow, if not than maybe it's because of the dual channel memory? It should be fast as hell with 1.5GB dual channel memory. I'm wondering if linux supports dual channel memory properly yet.

The nForce2 AC97 Audio Controller (MCP) is working but it failed to detect the onboard nvidia ethernet card.

Also I've installed linux on my IDE drives and managed to automount all my windows IDE partitions successfully but I'm having issues with my SATA drives. I'm running dual WD 10krpm SATA drives as RAID0 (stripped) in windows and I'm not sure if linux will be able to read the data on those partitions. It looks like it created an entry in /etc/fstab for my SATA raid configuration but it's not readable:


/dev/hde1 /data1 auto noauto,user 0 0
Does that look like it could be my SATA drive?

Anyways to SUM it up here's my system specs and any links to locations with help on setting up this hardware would be appreciated.

The dual channel memory I'm not certain about, but since its all on the BIOS level, Linux should be able to run at whatever freq its given, or the kernel will panic. If you dump in the whole of "dmesg" it might clear things up.

The Sata issue is just that the necessary support is wandering into the kernel very slowly. What's the output of:


That'll have in it the sata controller you have.

The errors from the nvidia module install... are caused by their being a precompiled aspect to what looks like ham radio modem drivers? Regardless, the last part of the Nvidia script is running depmod -a, which updates all module dependencies accross the entire module directory structure, so it bumped into those... it finished otherwise. Did you edit your XF86Config file to load not the crappy default "nv" module, but the one you got from Nvidia, "nvidia"?

nvidia also provides source code for the ethernet card, its on the site... wonder what kernel SuSe shipped with, its been in there for a little while now, at least since 2.4.22 hit final.

You shouldn't be accessing the striped partitions directly (this can be harmful!). Access the stripe set instead - the device is /dev/md0 usually. You might want to read the LVM HOWTO to get some useful info on handling logical volumes and RAID in Linux.

Also, SATA support in Linux is horrible. Use hdparm to view and set the correct settings for your SATA disks, but still you will probably see worse performance from the SATA disks than from your regular ATA disks. Lets just hope Linux SATA support gets improved...and soon!
