Title: Z68M-D2H BIOS issue with F6
Post by: isaacks on March 19, 2012, 02:46:48 pm

I have the Z68M-DH2 with two WD5000BPKT in a raid-0 setup and an I5 2500K CPU ( Sandy Bridge, family=6, model=a, stepping=7 (ext= 6,2a,d2 )
I updated to F6 and the raid no longer stable.
if I run HD tune and try to verify the disk it works over about 25% of the raid and then the drives completely locks up and the system reboots.
The system doesn't want to overclock but even with all overclocking disabled it can't read the raid well.
sometimes the system would say one of the drives had been disconnected before locking up.
I've removed each drive and tested each separately with the WD tool for testing their drives and found no media errors ( or any errors )

Thanks to the wonderful Q-Flash I was able to downgrade the BIOS to F5 and now my system is stable again. I'm not 100% happy with the raid performance, there seem to be spikes of very slow disk access ( 2M/sec as opposed to the more normal >200M/sec ).

I'm running Win7 x64 with Intel RST 10.8.0.1003.

Hi

When you flashed the BIOS did you disable the Keep DMI Data option on the QFlash mainpage ?

After running the update did you set up the RAID again before booting into Windows ?
