Anyone tried to flash the onboard SAS controller to IT mode?
I

I have created a zip with the necessary files to flash the onboard 1068E to IT mode.
Here: https://www.livreti.com.br/itfiles/1068E-Z800.zip

Just unzip this file to any DOS bootable usb and run hbaFlash.bat.
It will start a menu based flash process, you need to answer some questions:

Y - for backup
2 - for 3081 ( this is the same as LSI SAS1068E)
e - for pciexpress
t - for ti mode
6 - for B3 rev.( I bet all Z800 use the B3 rev. )
F - to confirm flash
Y - mismatch vendor id or product
Y - write IT over IR firmware

Or rather simply type: "sasflash -o -f  3081ETB3.fw -b mptsas.rom"
AFAIK, the mptsas rom is not really necessary ( I know it is troublesome with M1015 / PERCH200/300 9211-81 crossflashing ), unless you really want to boot off from a HDD connected to the onboard 1068E.

And it's done, now you have a total of 8 SAS ports working in HBA mode, or 14 SATA in HBA mode  ( 8 LSI1068E + 6 Intel AHCI ) 8)

Now you can play a bit with FreeNAS and lots of disks ;D

Hi all.
I'll soon post my build, in a week or two.

But now, I REALLY NEED an information about the DPS-1050CB PSU.
I just got one, used, and I need to know a simple thing: Is it normal for this PSU ( or DELTA/HP's PSUs  ) to turn on when powered without the 24pin ATX connected to a Mb?
If I plug mains without a mb connected, it turns on, as if shorted GND + PSU_ON pins.
If I plug mains, with the 24pin ATX connected to the mb, it works as expected.

Is this behavior correct? I need to know before I pay the dealer.

Hi all, I'm working on an "not-so-official" pinouts guide for the Z800 mb and I'd like you attention to P91: MEMORY FANs: fisrt attachment

Please help me fulfill the "P91 MEM FANS" pinout and I'll post the complete pinout guide WIP for review.

Hacked Z800 in its "own" case

Unfortanely long before Andy's great article I started hacking my Z800 in its own case.
I had a problem with the loud sound of the machine when I bought it. I like very quiet machines....

Great mod!  I was looking forward to doing this to my own case as well!  How is the noise profile under 100% cpu and gpu load?  And do you have sufficient airflow?

Here's the final WIP, awaiting for review/P91 pinout confirmation.

I found the information you are looking for on page 8 in this thread:

Memory fan is from top left to right:

PWM, PWM, TACH
TACH, 12V, Ground

Hi

Does anybody know, how to regulate the fans: front, rear and ram with fanspeed?
The cpu-Fans work perfekt, but i can not get access to the other fans.

Thanks for help

Tom
