I've just stumbled on something with my vNB voltage ripples. I'm currently working on getting my lowest FSBT and I've dropped it a lot and my vNB ripples are still their way less ripple. I'm really loving the logging of the 1.2.0b OCCT. It's been the biggest help in finding my issues with instability. Here are my vNB at 1.47 FSBT and and 1.27 FSBT.

1.47 FSBT (BIOS)


1.27 FSBT (BIOS)

The only thing is that on 1.47 FSBT you ran OCCT on Large setting, while in the second you ran on small. On small, it will stress the CPU, and quiet not the NB-RAM. The calculation data is so small it fits the CPU cache, so no need to go in RAM --> NB and RAM not tested much. Maybe that's why you got no cripple in second test.
The RAM mode is the mode that will stress the much RAM and NB. remember, that the main difference between modes is the data size. Small data remains in CPU cache, big data is transferred to RAM through the NB
Would be interesting for you to vheck also your NB temperature when you crash, also the VDIMM voltage noted to fall by others. The RAM on this boards has two PWM that can also get too hot --> ram voltage drop

Just some ideas to explore...
Also
Speedfan logs can be of a huge help too. Whatever kind of crash, even OS reboot, the log file is written to HD in real time and saved. So, on reboot or recovering of a blue screen, you open the previous log (as speedfan creates a new log file on each start) and you can see the values of your logged settings at the crash second. It helped me identifying a vcore delayed drop after 2h of stress testing: my PWM were getting hot and delivered a lower voltage to CPU

oh, btw, still no luck with the RAID intsall... something is just not right. i can't understand why it's not working. i keep getting hangups with the dvd drive for some reason and just a load of other stupid issues.

Silly question maybe, but, you're setting your RAID while overclocking? If yes, than try at stock. If not, ignore my comment

I'm going to run this OCCT for 12 hours and see how it does.

It's a very good idea to make a first full check and tests at that 3.6GHz point. So, if it is rock stable, unbreakable, you can go ahead basing your settings on the 3.6GHz reference point. But, hope you can get higher later. It'll be disappointing to see the Maximus topping at 3.6GHz as a rock solid setup, and to see that anything above that is not stable on all benching programs

just an update, it seems that i keep getting and error on one of the drives in the posting raid screen... i ended up using the ichr8/ichr9 for desk/work/server driver instead of the ichr7 one that most have said they're using... could this be a problem? oh, and to even start to come close to completing the install, i had to purchase one of those things... you know... the things we used about 20 years ago. yup, you guessed it, a floppydiskette drive! my usb one wouldn't work. ugh. next i'll be testing the harddrives through windows.

anybody know of any good HDD testing programs???

Windows check disk, and tick: check bad sectors. Long test, but tests read/write operations of all clusters
