Getting RAID to work on the ASUS Maximus SE

[Talonman]

RAM is good now. Just successfully tested with Memtest to 447% with 0 errors.
I just took a peek in 'extreme tweaker', and I found DRAM Frequency, command rate, timing control, static read control, everything but voltage...
I will keep hunting, thnks for the over volt advice too dude! .
System has not crashed again ever since I took that 1 stick out.
FYI - My Samsung 250GB drive showed up in the Storage Manager just fine. Formatting done.
Caviar750GB also showed up in Storage Manager, Formatting that big dog now....
All 4 HD will be up and functional.

I have 2 more questions..

1) Just to confirm, there is no "Write Back Cache" to select when using RAID 0 correct?

2) I downloaded and installed The HD Tach program v3.0.1.0 showen earlier in this thread, but when I go to start it, it tells me Windows200 or Windows XP is required. It look like others were running it on Vista 64 Ultimate.

Update: I just got the word that it needs to run in XP compatiable mode. Is there a better RAID performance program to test with, that would just run in native 64bit Vista mode?
