yeah, i tried different ram in that slot and tried the the other motherboard i had same issue. In HWINFO it only shows 5 memory controllers, the other cpu show 6. I will try the original bios that you created at some point, kinda nervous to mess with the system that is running. You definitely called it with the memory issue, its always a process when building

Sounds like RMA CPU time then, hopefully they will swap it out for you without hassles! I'm sure the other BIOS works fine, but yes, if you test please let us know so it will be documented here for those CPU's (if they need latest ucode or older one in original mod BIOS is OK too)
I agree, it's always something, especially when it's suppose to smooth and easy Glad you are at least up and running now

Lost_N_BIOS there is an updated bios on asus website, looks like they went and made it possible for you to run ES chips. I flashed the new bios unmodified and it is working. Comparing the new bios to the one you made for me using the X11 bios, the microcode revisions match. Very interesting development. Looking at the first mod you did, it wouldn't have worked with my es chip. The CPUID is 50655 but the ucode is 3000010, the original mod you had the ucode/revision was 3000000. There is always a chance they botched the new bios and come out with yet another one that might have to be modded but for now, they match the supermicro 50654, 50655, 50656, and 50657. They did not include 50650, 50651, 50652, and 50653 in the new bios from what i could see using MC extractor.

3000000 may work with your CPU, you haven't tested yet since your new memory, I think it would be fine. 50650-50654 are usually early ES, especially the 50650-50651, so that is why the removed those.

There is a cpu's, ES versions of 3175X, but they run only on Dominus Extreme and Asrock Rack WC621d8a-2t
26/52 ~500$ 28/56 700$

On the way Pro WS C621-64L SAGE, would be interest to put 3175X ES on this board.
ES 26/52. price on taobao 500$

Single CPU or Dual works great!
Thanks!

Guys, found this thread trying to get my c621 sage to work with B0 CPU mcode 80000037, this is some es 26 core QL2K cpu.
The board just sits with post-code 00 and red led is on - according to asus manual this indicates "catastrophic failure". :/

I didn't see anyone post this. I have seen this come up in a few forums unrelated to this exact motherboard but they had a broad spectrum of what it might be. Sidenote this is my buddies sage board that I built for him awhile ago... I guess he finally filled all ram slots and realized the attached error. It technically still posts... Boots and runs pretty well but just seeing if anyone had any thoughts on this?

Testing so far. This makes me think it is the board itself. Also he sent it back to Asus and the did find bent pins and was going to charge him over 1000 dollars to fix it (obviously more than the board is worth).

So I have changed out ram (I have enough of the same ram to fill up every slot from my build plus the ram he sent. Still same issue

I have swapped CPUs into the others socket. I have put both of my CPUs in and still same error at post. I did fix some of his bent pins in both of his sockets and actually got it to acknowledge ram filling up cpu0... But still different error on that socket. It just reported 0gb in that one.

Anyways I even brought the bios back to stock and updated it properly too make sure it was done right. Still same error at post and in the bios as well.

@Lost_N_BIOS any thoughts on post 324? sorry linking your name on my phone wasnt working for some reason.

@sochotek take some pictures from the socket. the 3647 is very fragile and if there are some bent pins than that could be your problem. had the same problem with a dominus extreme, few channels didnt show up cause of some bend pins. but it´s possible to replace the socket.

@oldirdey 100% agree by far the worst socket to work with. now i know my mistake was probably taking everything apart and shipping it packaged up great but he still had to put it all back together. i should have made it more apparent that this is a fragile socket.

so i thought i fixed all the pins but literally looking everything over with my magnifying glasses i did find one that looked very short and unable to bend back to the right alignment with the other pins.you will see that in the attached as well.

where would you get a replacement socket for the LGA 3647 i found one from Australia which isnt a bad price but was wondering if there was any here in the states?

@sochotek seems that 2 pins are not aligned and the 3rd one in the middle lost his head. take a look at the picture then you know how the pins looks from the side.



here you can order a new socket, but you have to find a company that will change it for you.

sorry wrong posting.

@Irgen - what is your CPUID or SSPEC off that CPU? If it is QL2K, 50652, then it should be OK working with the 8000037 in the mod BIOS now, be sure you have compatible USB Stick for the USB Flashback to work properly.
If you are unsure, test flashing different BIOS version of stock BIOS, and see if it flashes properly, if it does then you're good to go.

@sochotek - bent pins can easily cause those memory issues, maybe nothing you can do if you can't get the pins back to perfect.

@Lost_N_BIOS Yes, it is QL2K but the board does not post with both CPU's, single or dual, yet i specially bought QLH2 Funeral_YAR confirmed working and the board is posting.

Seller on ebay doing asus sage BIOS mod states mod is not compatible with QL2K - could it be hardware conflict, not the bios? If so i guess 500 well-spent..

@Irgen - hard to know for sure, what is true and what isn't. At first that ebay seller said it was only possible to pay him and send him your board, that he couldn't sell a BIOS and then it would work, proven to be a lie/misleading, so he could be correct or only guessing/misleading you.
I don't know, I don't have this board or any CPU's. Yes, it could be some hardware issue, or some other edit needs done, some further update from Asus needs pushed out, some ME FW edit needs done etc.
