ES Xeon Discussion

Aight. So ASUS/ASRock and Supermicro are my best options?

If you wish to try the ES/QS CPU, then a Gigabyte motherboard is your best choice.

W790
ES = ASUS/ASRock
avoid supermicro / Dell / HP / Lenovo of you want to run ES.
QS work on ALL motherboards who support the Retail version.
QS = prod.unit just with ES bit set.
if you see "0000" in BIOS or CPU-Z it is NOT a QS.

gigabyte only at C741 motherboards, gigabyte W790 do not support SPR-SP D0 ES like QYFS.
(but gigabyte BIOS is moddable)

Alright, thank you very much.

I read some documentations about intel bios guard over the last couple of days, and it seems like its deaktivatable in most cases as long as its not fused. Aas far as i know dells bios guard is not fused and safe bios is also deaktivatable, so what is stopping us from modding it?

the required Intel CSME Tool is not leaked for this version.
if you can , do it.
apart from that the add. parts(psu,front panel,case,fans,) we need costs much, so we can better buy a out of the box compatible motherboard.

if true, all that makes no sense.

Intel BIOS guard is a bios setting, you dont need CSME tool to change it, while the BOOT guard is often fused and needs CSME (if it even can be deaktivated)

WHat makes no sense?

 

[RolloZ170]

Intel BIOS guard is a bios setting

this vulnerable behave was removed and all affected BIOS removed from DL site.
i have changed the _FIT_ table of a 5860 motherboard, it was reflashed/restored and booted fine with w3-2423

 

[RolloZ170]

WHat makes no sense?

if you can disable security mechanisms that easy. time is over.

I bought a QYFS for cheap and the 06CX9 looks pretty promising for its price but it officially does not support the QYFS

Then i need to look out for another board. I dont really feel like paying more than 500€ for a board but that'll be hella difficult.

throw the QYFS away and all your problems are gone.
after the board comes DDR5 RDIMM, now 16GB costs $150usd because of Ai boom.
best value is ASRock W790, only quad channel but it is ok.

Isnt intel boot guard the thing that keeps us from using a modified bios and not bios guard in the first place?

no BIOS Guard reflashes modified parts if possible or stops Boot.
Boot Guard is used with TXT, but TXT executes startup ACM which erases memory to protect from RAM resident malware,
this is disabled if the Platform supports S3 sleep.

 

[Nima0908]

Ah, ok, thanks

 

[RolloZ170]

Ah, ok, thanks

and of course if there is a way and we did it, the motherboards rise in price. there aren't many of them anyway.

Hey guys.
Just got an MS73-HB1 motherboard and two Q30G CPUs. Which BIOS should I flash, and how can I optimize the BIOS settings?
Thanks in advance!

PM you.

I haven't modded a bios since 2011 Xeons, so I am curious.
Is this by adding the correct microcode for the CPU or is there more involved ?

 

[RolloZ170]

yes add the microcode is required, and disable ACM execution in _FIT_ (ASUS SAGE/ACE BIOS do not use startup ACM)
finaly you have to correct the checksum (footer of RBU file)
