Booted 1st time after pulling a CPU.....
in retrospect I guess low voltage means higher current ??
maybe trying to step from 12gb to 96gb is too much power drain ?
to all who have posted

Thanks for your prompt reply,
I have 2 processors, therefore the sticks have to be in the configuration set out (black slots).
I don't know any other configurations I could try,
The 24gb I had originally, came out of the same black slots, meaning the slots aren't at fault?
I know some operating systems aren't as fussy as Windows, which is why we tried Ubuntu.
I also believe it's something to do with Windows, but nobody else seems to have the same fault that I do. Which is the spinning dots crashing on Windows 10 load.
I also have all the drivers up to date, and BIOS flashed to the latest version (ver3.60)
Thanks in advance,

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

About the cable sensing, I know it's by grounding the "detect cable" pin...
About the thermal sensor, here's some insight: http://h30434.www3.hp.com/t5/Business-PCs-Workstations-and-Point-of-Sale-Systems/HP-xw-SERIES-THERMAL-SENSOR-TRANSISTOR-SWAP-TUTORIAL/td-p/5156011
Pretty simple, huh? I just have to check for pinout in xw series service manual.
I've just got my board, it had some bent socket pins on CPU1, I'll fix it later when I get my hands on some test CPUs...
BTW, it's rev 03
But I'll try to find a way to disable the BIOS BootBlock WP, I have all the tools to hack it and get it back in one piece.
Of course I'll get it running before messing around
All the tools to hack it? Like to modify the BIOS and flash a modded BIOS back to the board?

I hope this is my last post before I get my hands on the board!
According to this thread: http://h30434.www3.hp.com/t5/Business-PCs-Workstations-and-Point-of-Sale-Systems/z820-e5-2600-v2-ivy-bridge-upgrade/td-p/5086052/page/7 , there's hope:
"I was pretty excited when I was able to dump the Descriptor section from my bios using FPT to a file desc.bin (fpt.exe -desc -d desc.bios). The result is a 4kb file. Then, using Intel Flash Image Tool (FITC) I edited Decriptor Region \ Master Access Section to remove the read / write locks. A problem however arouse on the last hurdle - flashing back the modified descriptor to the bios (fpt -desc -f desc.bin) as FPT reports that 'host CPU does not have write access to the target flash region'. It suggests modifing the descriptor settings (clearly just tried that with no success) to give host access to this region."
I am the author of the post you quoted. Bear in mind that that discussion was pertaining to the Zx20. I have very little knowledge of the Zx00 platform, however do recall that the board itself underwent some revision during its lifetime (4 RAM slots and then 6 RAM slots) + supposedly some chipset changes so I can not comment whether just the changing the boot block will suffice in terms or running the newer processors.
As for the Zx20 and perhpas also the Zx00 there is a method of unlocking the descriptor - you need to connect / short pins 1 and 5 on the sound chip with a 1k ohm resistor during POST. THe board will be in debug mode until reset allowing you to fully dump your bios and to write to the descriptor and with the various jumpers (boot block, me) in place to the rest of the bios. Just bear in mind that it is VERY EASY to end up with a brick if this does not go according to plan. There may also be other security features / locks in place on the actual bios chip which despite the appearance that you are able to write to the bios from the chipset side will result in an error halfway through your write and render the board inoperable. ALso, since you will be able to write to the entire bios, it may be the case that a failed write will corrupt your boot block to the extent that you will be unable to recover using the boot block recovery feature. You have been warned.
Check my response to the Z420 bios thread on this forum, I outlined the steps needed to safely update the bios boot block in that thread - basically installing a socket and programming a new bios chip with an external programmer. An external programmer with a chip clip is perhaps also an option, however these can be hit and miss hence I would not recommend using one without being mentally prepared that it may be necessary to desolder the original bios if things do not go according to plan.
PS. re the picture you inserted - crisis recovery jumper is for restoring the bios using boot block recovery. It will not grant you write access to the boot block area (FF0000-FFFFFF on the Zx20). On the Zx20 boards there is a separate jumper for that.

Can anyone help me with determining what temperature sensor is used in Z800 (thermistor) power switch/speaker cable assembly?
Hi, Check out this post further back in the thread.

I'm wondering these post messages make pressing F1 a requirement:
If yes, has anyone managed to get these ports "sensed".
I've just ordered a Z800 board and I need to get this problem solved, It'll be used as a server!
Have a look at Attilio's posts on page 14
