ASROCK RACK SPC741D16X-2T no post code ff problem

[DHamov]

Hello,
i received an Asrock Rack Board SPC741D16X-2T. It is an dual cpu intel 4677 board.
When turned on with a single cpu, and single rdimm it gives code F.F. and it does not post.
in the BMC-Gui and ipmi i can not find any error, or problems.
I connected the ATX main power cable and 4 x 8 pin power cables, the power switch and reset switch pins.
However i am not running this in some server case, but a normal big case, so no further connectors are used.
Also i use Noctua nh-u14s-dx-4677 Heassink and cooler that has 4 pin pwm instead of the 6 pin-Asrock connector.
Now the main particularity is that i try to use intel xeon ES 8490H Q03J cpu's. Compatibility is not confirmed, so this could be the main issue.
I was also already on the Xeon ES forum thread here.

My question here is just to make sure that i did not make any other mistake before i give up on this, and blame incompatibility.
And return the Motherboard to the US.

I tried booting without any other devices: no usb, no vga, only cpu, memory --> code ff.
I tried several cmos resets, booting without memory, with all memory with 1 memory, without battery, different cpu single socket, both cpu dual sockets, other PSU, and different combinations of power cables. with gpu, without gpu, everything ends in code F.F and no post.
Only booting without cpu dit not result in code FF. But also nothing else interesting happens.

Does anyone have any further suggestions about what i can try? Is it mandatory to connect some special headers or connectors besides power and reset?

Can you please post the photo of the CPU headspreader? I wonder what stepping is this ES.

 

[DHamov]

Sorry it took a while i was not at home. Here is the cpu and heatspreader.

That is the strangest looking CPU I ever seen. Starting with the fact that it does not have a logo. On D stepping Xeons Intel used an old round logo that looked like this:

On E stepping and retail chips Intel uses a new square logo that looks like this:


Your chip has no logo at all. Plus it has frequency after the designation which was dropped on the E stepping. I do not want to start panic but that chip looks very suspicious to me. May be it has logo but camera did not caught it? But anyways that might be a compatibility issue - chip might be incompatible with that board. You can try to get the full POST code sequence from IPMI for the last boot attempt but if it starts with FF and does not progress further that is a dead end - system does not recognize installed chip as a functional CPU and can not move any further.

all SPR-WS ES do not have frequency.
this depends also in which factory the ES was assembled

 

[DHamov]

Oh little hart attack.
OK there is a round logo, but yes the camera did not get it i will make another picture.

But it seems that the round logo, means its not an E-stepping?
i know the difference between the round and square logo can be important.
With 12900 chips, some of the ones with the round logo have AV512 while the new ones have not.
Oh gosh, i will try it in a w790 board, and put my Q03J, to see. If it boots its a D0 and not E0.
Theoretically i could also still return the cpu's although i dont know exactly if the item must arrive back in 30 days.
On the other hand the ebay stock pictures of this 8490H look exactly like mine.
Which does not mean any thing, maybe they were all painted by the same artist.

all E0 i have seen have round logo and frq.

 

[DHamov]

Oh Man why did i not try this, before when i had the chance.
I can get the 8490H Q03J to post in the bios with bios 2.2 on an Asus w790 Sage, and linux loads.
Is there some linux equivalent of HWinfo to check this?
Otherwise i need some more time to get a windows install.

in the BIOS you can see cpuid 806F3 D0 or 806F4 E0

 

[DHamov]

It says 806F4 - SPR-SP E0
and below 000806F4*

1.6GHz

nice, (for the SAGE owner)
we have tested Q0K? E0 on ASUS W790 Ace = not working.

 

[RolloZ170]

Oh Man why did i not try this, before when i had the chance.

because i told you it will not work

 

[DHamov]

Some how i have this feeling that the universe is ironic and that Q0K would then maybe still work on the Asrock.

Q03? is earlier (closer to D0) than Q0K?
3 456789ABCDEFGHIJ K

 

[DHamov]

But if it is like 4 minutes work, i normally never listen, so its really just my own lazyness and lack of curiosity.

Do they count like that or do they count like ABC...XYZ012....
i think the last one right after QYFS it came Q0 hmm then Q0K must be more young old than Q03.
Maybe it is also not depending on that, but on different factory lines. Two or more different type of E0?
I really do not understand.

Booting in windows on a stick gives AA code.

 

[RolloZ170]

Do they count like that or do they count like ABC...XYZ012....

Z ist last char after that the Q0** comes to Q1**
QX**
QY**
QZ**
Q0ZZ
Q100
Q2**

 

[DHamov]

Thanks for the help guys.
Well at least we know:
-its a real E0. (But it was good that Kizune doubted this)
-Some E0, work in W790,
-and at least one of my Q03J is not broken.
-Asrock Rack c741 board and this E0 does not seem to be working.
But very curious about Q0K

 

[RolloZ170]

-Asrock board and this E0 does not seem to be working.

maybe Q0K* is working on ASRock Rack C741 ?

 

[RolloZ170]

-Some E0, work in W790,

hehe, ALL E steppings should work on W790 if they are WS parts.
