P5K Premium issue

[thefiddler]

Hey people!

I already posted this message, but it was somehow buried into the P5K Premium testing report, and as I'm quite stuck with those issues, I prefered to open a new thread instead.

So, the problem is I keep getting errors. Not that often, but it's annoying. Most of the time, the computer slows down, and here are the errors showing up in the Event Viewer:

1. "The device, \Device\Ide\iaStor0, did not respond within the timeout period."
2. "An error was detected on device \Device\Harddisk0\D during a paging operation." (usually shows up 5 to 10 times at once)


Sometimes, the computer just makes a BSOD instead of slowing down. After the BSODs, here's what the Event Viewer tells me:

1. "Error code 00000077, parameter1 00000001, parameter2 00000000, parameter3 00000000, parameter4 a44d1d24." (after first BSOD)
2. "Error code 00008086, parameter1 00000000, parameter2 00000000, parameter3 00000000, parameter4 00000000." (after second BSOD)


All of those errors and BSODs happened while I was copying/moving large files from one partition/drive to another.


Here's my actual setup:
- P5K Premium (BIOS 0402 beta, rev 2.00g)
- Core 2 Quad Q6600 (G0)
- Corsair DDR2-8500C5D (2x 1GB)
- Seasonic S12+ 550w PSU
- SEAGATE 7200.10 320GB (x2 - model ST3320620AS - SATA2 enabled) in AHCI mode

OS: Windows XP Pro w/SP2
Intel Chispet Driver version installed is: 8.3.1.1009
Intel Matrix Storage version installed is: 7.6.0.1011


What I already did:
- checked that the mobo's BIOS was updated correctly.
- ran SeaTools on both harddrives: both of them passed all tests (except destructive ones, which I didn't run).
- ran Memtest 1.70, made 22 passes successfully.
- disabled LPM technology by renaming its registry key, didn't make any change [EDIT]
- activated Marvell Yukon LAN adapter in Windows, didn't make any change [EDIT]
- disabled the Marvell Yukon LAN adapter in the BIOS, no effect [EDIT]
- upped the RAM voltage a bit to the spec voltage (2.1v), didn't help [EDIT]


I don't know what's wrong. If any of you have an idea on how to fix this problems or at least how to point at the defective part, that would be great

Thanks!
