Abit kt7 raid instability.....need advice!

Hi,

Having just purchased an Abit kt7 raid and t-bird 750, I am running into the following situation, severe instability. I have tried several things. They are as follows:

Ram, initially had KTI tiny bga 133, went to Samsung -GA 133, no diff.

250 watt superpower supply, went to Enlight 300w p.s. no diff.

If processor is clocked at orig 750 and No enhancements, then its stable, as soon as its overclocked in the least, instability. Even at 750 with enhancements its unstable.

Went from Windows Me back to 98se, some improvement, though could be linked to different ram.

Changed from Aureal Vortex2 card to generic sound, helped somewhat, only because I believe of the additional irq saved.
Switched items around in the slots, no diff.

Reseated processor and heatsink, no diff.
Changed numerous bios settings, from advice on kt7 page even though I am unsure of what exactly their function is. This is a real touchy situation as it can make the board extremely unstable.

My system is as follows:

T-bird 750 W/Alpha heatsink
Kt7-raid
Samsung -Ga pc133 run mostly as host clk, because host+pci is a problem
IBM 30 gig 7200 ata 100
Quantum 15 gig 7200 ata 66
Western Dig 6.4
Toshiba 48x cd
Plextor 8/20
Sandisk usb smartmedia reader
Ensoniq sound card (for now)
Adaptec 7850 Scsi 2
3com 905b network card
Generic Isa scsi card for scanner
Tnt card for now as Geforce is extremely unstable

Anybody have any ideas or suggestions please advise, also recommended bios settings would be greatly appreciated. I am pulling the hair out as we speak!

Thanks!!
 
Just a shot in the dark, but did you try removing your scsi controller? I don't know a lot about the KT7 RAID, I got the plain KT7 and it will get here some time next week with my Duron 700🙂 Anyway is their a Via 4-in-1 driver for the KT133? Try installing the badboy, worked wonders on my Tyan Trinity 400.
 
Well, I can't remove the adaptec scsi card, because it runs the plextor drive, but I can take out the isa generic scsi card, and yes I got the new 4 in 1 drivers and the did help a little..I will try that soon.

Thanks....anyone else?
 
I had lots of problems last week too. Turns out my adaptec 2940 was sharing an IRQ with the HPT 370 and they didn't want to play nice. It's important that the HPT 370 gets its own IRQ. Keep in mind that anything in PCI slot 5 automatically shares IRQ's with the HPT 370.

Hope this helps.....
