Anyone willing to help?
Deathbringer from biosmods did his best I guess but his bios modded results in exactly the same behaviour.

NOTE:

I have a 370DLE that did exactly the same, used a bos update from Supermicro with support for Tualatin (on P3T, the bios is the same), solved the problem and now works perfectly with LinLin adapters.

Maybe P6DBE bios has a whitelist of some kind also? This could explain why even microcodes won’t help.
Is there any bios modded willing to help?

exactly the same what? first you wrote one of cpus was dead, then you wrote it boots

Not sure what you mean or what you are trying to start…

The 370DLE had exactly the same behaviour, same screen showed at post, with the cpu I was thinking was dead.
Then with bios update it works.

I simply do not understand what is the question.

>one of the two SL5XL is not functional

>Actually on a 370DLE with LinLin it works (gives the same screenshot anyway, no microcodes, but the post complete

>I am sure it would post ok with proper microcodes

? Lets start with you defining your understanding of the word "post". Because as far as I see it _anything_ on the screen is a 90% of post passed.
Do you mean computer hangs at this screen? refuses to boot?

>The 370DLE had exactly the same behaviour, same screen showed at post, with the cpu I was thinking was dead.
>Then with bios update it works.

and why would you think a cpu that shows a post screen is dead? Because it says "unknown"?

-We are talking about dual slot motherboard, so two CPUs are involved.
-I have two Tualatin-S cpu, I was thinking one of them was faulty.
- The motherboard hangs at post (with one Tualatin installed), exactly with screenshot attached. It stops there.
- The motherboard works normally with only one coppermine installed, no terminator needed. Posts and loads OS.
-Forget about the “faulty cpu”. It is not and the request is not about it. The cpu works, both cpu work. Please let’s focus on the request, if possible.

I'm guessing they think the 2nd processor was dead because in the boot up screen it should say 1000MHz x2 if it is detecting both processors.

For the OP - Best way to double check is for them to test each processor by itself in that board and make sure they both boot. I would force the voltage setting through the S370-DLs instead of through the Lin-lins and I'm kinda surprised it posted at all, I would reseat you Lin-lin adapters as they dont look fully seated.

This is how my Lin-lin looks fully seated in my S370-DL

{edit} I was typing this I guess as Mamba was posting above post

It may not work at all, I dug back through my old bookmarks as this subjet seemed familiar.

Conclusions: SUPERMICRO SUPER P6DGU dual slot 1 motherboard seems not to work with Tualatin low voltage CPU cores.

That qoute is from here. Disclaimer: not my site just an older webpage I have bookmarked when doing some research for my P6DGS.

Thank you but… The chips work perfectly.
Please don’t stick on the dead cpu thing. It is not.
They both work in 370DLE motherboard.
I know the P6DGU attempt but here is different. On the P6DGU he obtained nothing, black screen.
With my P6DBE I see a partial post (it hangs), exactly like it did with the S370DLE before bios update.
So again, only to put Tualatin microcodes is not enough, the bios must be modded further probably to eliminate other limitations it may have (whitelist?).

I am asking bios modders here (Ami)

What else do you have plugged into the motherboard?

Have you tried without drives connected? What about disabling onboard devices?

It could be a timing issue with the Tualitin CPUs.

I cannot do anything, the post hangs there. Nothing is connected, only ps/2 keyboard and vga of course.

switch to one coppermine and disable everything in the bios that can be disabled
what is POST card saying when it hangs on that screen? will tell us precise bios section that has trouble

Will do.
I don’t have post cards, unfortunately.
I know I need it.
On Amazon I saw one or two but reviews were terrible, do not know which one I should get.

Probably not that surprising that this latest BIOS mod didn't work...seem to recall you had pretty much the same results (failure to start or mis-reported cpus) when doing the same kind of tests a while back using your P6DGE and the BIOS I added the Tualatin codes to (the P6DBE & the P6DGE are fundamentally the same board apart from the chipset - BX ang GX respectively...they even share the same BIOS). Both these 100MHz boards are likely fine with 133MHz fsb coppermine cpus (they even have a BIOS option to bump the fsb upto 133MHz) but they do seem to have issues with cpus running natively beyond 1GHz.

Maybe past 1.1 GHz as I tried a pair of SL5QW (coppermines) running on my P6DGS and it seemed to run W2k just fine although I didnt do a ton of testing as I worry about if the VRMs were designed to handle that wattage on my board.

Ah, I did recall someone having been beyond 1GHz on similar SM dual slot 1 boards, but not whether it was coppermines or tualatins - have you ever tried the latter?

Also, based on your success, maybe the BIOS and board revision play some part - the P6DGS and the P6DBE (PCB REV 0.xx/1.xx) share a BIOS, but not the P6DBE (PCB REV 2.xx / REV 3.0) as the OP has

P6DGE gave me black screen
P6DBE at least post something even if hangs.

I have not tried any tualatins as I only have 1 lin-lin adapter and was always planning on running this board as a dual setup. I only have a stock bios on the board and it does complain of unknown microcodes but runs just the same.

I am just replying to your question as unfortunately I dont have any insight to help the OP get dual tualatins running on his board.

For unknown reasons I cannot enlarge your picture not even on imgur.
Could you add here?
It is on a P6DBE?

Nope its a P6DGS
