Intel CPUs: Xeon E5 vs. Core i7

You do not need a server board to use a Xeon E5 v3 CPU. Most X99 motherboards work great even with Reg ECC memory (although Reg ECC memory is usually not officially supported)

While most desktop boards will not have support for vPro and TXT, we have been able to use Xeon E5 v3 CPUs and registered ECC memory on every ASUS and ASRock X99 board we have tried without few, if any, problems. The eight RAM slots on most X99 boards will limit you to a maximum of 256GB (8x32GB) of RAM instead of the 768GB the Xeon CPUs technically support, but that is the only issue we’ve seen. In fact, we are currently using Xeon E5 v3 CPUs on the ASUS X99 Deluxe motherboard on all of our Genesis I and Genesis I Quiet Edition systems. This lets us have up to 18 cores and 256GB of RAM in a workstation without giving up desktop features like USB 3.0, onboard audio, or WiFi.

It has been known that X99 is ECC ram compatible in native. Manufacters, like Asus, has tested ECC momeries only on small portion of mobos and gives full support for them.
It there anyway to increase the options of ECC in UEFI with mobos that is not fully supported by manufacter? Is there some hidden options or combatible UEFI modules over all x99 mobos?

examples of nativelly supported boards:
ASUS X99-E WS
ASUS X99-M WS
ASUS X99-WS/IPMI
ASUS X99-E WS/USB 3.1

For X79 with Xeon e5 v1 and v2 CPU Ecc unbuffered worked fine, however i could not boot with ecc registeted. This is on an Asus P9X79 Pro board. Bearing in mind that on both X79 and X99 the memory controller is on the CPU my feeling is that this is an artificial intel imposed limitation, probably via the ME.
Its a similar story of ecc being supported on i3’s but not on i5/i7 or with the E3 xeons being locked out of the consumer 1151 platforms — standard Intel bs.

I am using Xeon prosessor, but before to order the memory kit I am still worried about possible lack of watchdog and communication between operating system and momery modules case of bit corrections. If I have understant the whole thing right.

I compared Bios files in UEFITool and in the first look I didn’t find any additional UEFI module. Bios files modules and order of the modules is almost indentically.

Yes, some BIOS have hidden ECC settings disabled. What BIOS particularly do you want checked out for this kind of settings?
I wont look through a bunch for you, that would take too long, but if you have a board or two in mind I will check for you.

I own Asus X99-A/USB 3.1 and I am comparing to X99-E WS/USB 3.1.
I noticed just that there is one number difference in embedded controller version. Could there anything to do with ECC memories?

X99-E WS/USB 3. 1
PCH Stepping: 5/C2
EC1 Version MBEC-X99-0427
EC2 Version: RGE2-X99-0206

X99-A/USB 3.1
PCH Stepping: 5/C2
EC1 Version MBEC-X99-0426
EC2 Version: RGE2-X99-0206

Yes, I am trying to get full support for ECC. Any idea where the embedded controller might be? Name of the module? Is that DXE or PEI driver?

Thanks for help.

EC update is often separate from BIOS, are you sure it’s in Asus BIOS itself? Did you check all the available download files on Asus site?

I will look at the X99-A BIOS for you tonight and see if any settings for ECC are hidden. Do you see any at all? If yes, what all do you see regarding ECC?

Thanks for your effort. Remember look for X99-A/USB 3.1

Asus bios files updates EC. You cannot updated it separately. That is all I know.

Does anyone know what DXE driver: platform stands for?

@Sylar76

Also UncoreInitPeim module is slightly different. Am I right that format some dram behavior?

Sorry, but maybe I too noob for this kind of working

Start reading from side 25. It´s Datasheet for V4 Processor but I think you can get similar one for your V3.

UncoreInitPeim module is strictly related to CPU Cache and DRAM behaviour of course.

But according to some tests I made with latest bios and cpu microcodes, it is better to keep the native Uncore module
instead of modding/replacing it.

I did not look in BIOS for EC, you said it was there so I assumed you were correct. It probably is, before you mentioned that to confirm, I had checked asus download page and no EX downloads so you are surely correct.
Sorry, I don’t know how to view/edit EC FW. Well I have only looked at one boards EC and it was OEM like Lenovo or HP I think, maybe Asus looks different? I’ll see what I can find, but I bet its same, all alien text in hex and no way to render or view otherwise in app or anything.

Yes, confirm it’s there, I see ECUpdateFramework, still looking for file itself — found them! As you mentioned RGE2-X99-0206 @ 128kb / MBEC-X99-0426 @ 128kb
Nothing I can do with those, sorry. One looks like it has some VRM freq control, fan control and SMBus stuff in it (And overvoltage fun literally it says that, part of tweakit app it looks like. The othher USB flash related stuff, but that’s all I can tell

The Asus X99 Deluxe II is an update to one of the premiere motherboards for Intel’s Core i7 and Xeon E5 processors. The X99 chipset on this board supports DDR4 memory, and unofficially also works with ECC Registered memory which is available in higher capacities. A host of connectivity is provided as well, with four each of USB 2.0, 3.0, and 3.1 ports along with dual Gb Ethernet, WiFi, and audio connections. Internally it has several SATA connections, one M.2 slot, and two of the new U.2 ports.

We are NOT offering the Thunderbolt add-on card with this motherboard, because it fails to meet our quality standards. This board, aside from that, is an excellent board and one we fully recommend.

William George (Product Development SME) Says:
This board sports Asus’ white-on-black color scheme, and it looks great in systems with a side window. It is also loaded with all the latest technology, so if you are looking for something that is future-proof this is a great choice.

Apart from the switch from DDR4 to DDR3, the model hasn’t undergone any major changes. All the pros and cons of the parent are completely inherited.

About revisions and BIOSes

Unfortunately, in 2021, new revisions were released for almost all top motherboards from Huananzhi, inferior to the first versions. Not spared and X99-T8.

A new revision appeared around the end of summer 2021. At the moment, all changes are not exactly known, however, it can be assumed that they are similar to changes in Huananzhi X99-TF and X99-F8.

Presumably, the changes have been subjected to:

  • Power Substitute (now weaker Mosfets Production of XIAMEN)
  • Multicortroller (replaced with Nuvoton NCT5532D to NUVOTON NCT5567D-B)
  • Audiochip (now used ALC883 \ ALC88) BIOS (changed from Winbond 25Q128 to Macronix MX25L12833F)

However, the problem lies not only in the changed characteristics of the board. Changes have also occurred in the bios, in addition, there were problems with the compatibility of bios from different revisions. nine0003

During the existence of x99-T8, Huananzhi released at least 6 BIOSes (the most convenient way to distinguish them is by the release date), and the differences between some versions are quite significant. There are also several versions of firmware from a third-party developer iEngineer released for the Huananzhi X99-F8, but successfully working on the T8.

In addition to the BIOSes themselves, we will also be interested in the performance of the Ultimate Patcher Tool (UPT for short), since it can be used to fix smartfan operation after the system wakes up from sleep, as well as apply the TB hack and control voltages directly from the BIOS. nine0003

What parameters we are interested in:

  • ECC operation (automatic error correction ram). ECC memory modules will work on all BIOS versions, but error correction itself can be disabled.
  • Ability to change Command Rate (CR) timing. In some BIOS versions, this timing is 3T and there is no way to change it.
  • Operation of all audio outputs. Depending on the installed audio chip and BIOS version, both all outputs and only the standard 2.0 speaker output + microphone output can work. In the absence of a 5.1 \ 7.1 audio system, this item may not be critical. nine0008
  • Ultimate Patcher Tool performance. Unfortunately, the utility does not work with all BIOS versions. Firmware of an incompatible version can lead to board corruption, after which you will have to restore the BIOS with a programmer.
  • In addition, there are other less significant parameters (turn-on speed, operation of temperature sensors, nuances of smartfan operation, etc.), which cannot be taken into account now.
bios version + (except smartfan)

What you should know about bios versions :

  • To access this functionality, it is better to immediately use the modified versions. You can take them, for example, here.
  • Bios from 2020-05-25 is unconditionally considered the best. This version is ideal for first revision boards with nuvoTon nct5532d multicontroller. However, problems may arise with new revisions: inoperability of 5.1 \ 7.1 acoustics, incompatibility with UPT or other shortcomings. In some cases, the firmware of the original version on the boards of the latest revision even leads to scaling. nine0008
  • Fortunately, at the moment there is already a modified version of the BIOS dated 2020-05-25, where all these problems have been resolved. This mod can be flashed onto the latest revision boards without much fear.
  • All subsequent BIOSes up to 2021-09-15 are almost the same. There is no working ECC here, the Command Rate (CR) timing is forced to 3, and the Ultimate Patcher Tool results in scaling.
  • There is firmware (CX99DE29) from 3rd party iEngineer for Huananzhi x9 board9-F8, but works successfully on x99-T8 as well. The original version from this developer has blocked regions, so flashing (as well as returning) is possible only with the help of a programmer. However, there is also a modified version with open regions, which can be flashed in a more familiar way.
  • UPD : a modified version of iEngineer’s CX99DE29 bios appeared with ported audio modules for ALC883, ALC887 and ALC888 codecs.

How to understand which version of Bios to flash

Before moving on to the firmware, we need to find out which revision of the board we got and what we want to achieve with the firmware.

Determine the board revision

Unfortunately, at first glance it is quite difficult to understand what version of the board is in front of us. The only significant difference is that the first revision has the marking G377Q ver 0.1 near the 24pin pad. But for reliability, it is still better to check the marking of the multicontroller.

Conventionally, revisions can be divided into old (with nuvoTon nct5532d multicontroller) and new (with nuvoTon nct5567D-B multicontroller). The multicontroller itself is located just above the speaker. nine0003

If the board is the first revision with the nuvoTon nct5532d multicontroller

We consider ourselves lucky. Feel free to download the BIOS from 2020-05-25 (I recommend the mod version from the Cat), run it through the Ultimate Patcher Tool and flash it in any convenient way (you can directly from under Windows).

We get the maximum possible functionality, stability and good mood.

If latest revision board with nuvoTon nct5567D-B multicontroller

Here everything will depend on the availability of the programmer, as well as your desire to get the maximum possible functionality (and a little more luck).

The safest option

  • We look at the date of the BIOS with which the board came (the Build date and time line in the start window when entering the BIOS)
  • you need a TB unlock — we do it through S3TurboTool
  • We flash it in any convenient way (you can directly from under Windows through the same S3TurboTool). nine0008

Advantages of of this option: minimal risk of bricking the board, access to timings, operability of all audio ports.

Disadvantages of : inability to change the Command Rate (CR) timing, most likely disabled ECC, inability to use the Ultimate Patcher Tool.

Modified BIOS firmware dated 2020-05-25 (programmer is desirable)

  • Downloading the modified BIOS version dated 2020-05-25 with transferred modules for audio from the BIOS dated 05/11/21 and the corrected descriptor. nine0008
  • We run the BIOS through the Ultimate Patcher Tool version 2.2 or newer. The program will automatically fix the error associated with the spontaneous boot of the system in Recovery mode. Optionally, we add unlock, the possibility of undervolting and a fix for smartfan.
  • We flash in any convenient way (you can use the same Ultimate Patcher Tool)

Advantages of of this option: timings, ECC, operation of all audio ports, all the advantages of the Ultimate Patcher Tool. nine0003

Disadvantages of : not noticed, but just in case it is better to have a programmer handy.

BIOS firmware from iEngineer (programmer is desirable)

This time we will use third-party firmware from iEngineer. The developer made a separate version for revisions with the nuvoTon nct5567D-B multicontroller. The original version has blocked regions and is intended only for flashing with a programmer, but there is also a modification that can be flashed without it. Another advantage of the modified version is 100% correct operation of all audio ports. nine0003

  • Download the original or modified version (link below on this page)
  • If you need to unlock TB, do it through S3TurboTool or Ultimate Patcher Tool.
  • Flashing in the appropriate way

Advantages of of this option: minimal risk of bricking the board, access to timings (including Command Rate), working ECC, some edits for more correct operation of Linux or Hackintosh OS.

Disadvantages : There may be some differences from the stock bios (for example, smartfan operation, speaker sounds when turned on, etc.). When using this option, it is also desirable to have a programmer just in case.

Firmware files and methods

  • You can flash the BIOS using the S3TurboTool or Ultimate Patcher Tool utilities (in both cases, firmware is performed using FPTW).
  • You can use FPTW itself without third-party utilities: download FPTW 9.1.10, open the command line (as administrator) and flash the BIOS directly from Windows with the command fptw64 -bios -f bios.bin . Where bios.bin (or ROM) is the modified BIOS that needs to be copied to the fpt folder. Of course, on the command line, you must first go to the fpt folder with the command cd .
  • A well-known method from the 2011 socket with a bootable flash drive and the usual FPT.
  • Using a bootable flash drive, you can flash through Afudos
  • Another option for firmware from under Windows is Afuwin
  • Firmware using the mi899 utility
  • And of course the most reliable way is a programmer.

After flashing , be sure to reset the settings .

If you wish, you can try other BIOS versions from 2021. The original and modified versions can be downloaded all in the same place, on Kota’s github.

Bios features

The functionality is completely identical to the bios for Huananzhi x99-TF or x99-F8 boards, but since T8 does not work with processors with an unlocked multiplier, overclocking is not supported. Timings management can be either present by default or hidden (depending on the BIOS version with which the board came). If there is no access to timings, you will have to flash a modified version of the BIOS. nine0003

As with all other boards, turbo boost unlock is possible.

May (dated 05/25/2020) original BIOSes and mods based on them (without built-in unlock) can be modified using the Ultimate Patcher Tool. This is the most modern way that will allow not only to apply the TB hack, but also to control voltages directly from the BIOS, as well as improve SmartFan performance when the system wakes up.

Where to buy

X99-T8 for sale on taobao and aliexpress. Ali sellers: 9Turbo LGA2011! Let’s go!

Everything was brought to me in a package. Bought a few months ago, according to the box was. It seems like they collected they collected, but they did not pick it out.

I’ll put a link to Atermiter, because very similar to her. Other «brands», such as PlexHD, put their logo on the heatsinks. So here, either a completely non-name, or a non-name with the name Atermiter.

A very vague explanation that “something didn’t work out”, in connection with this, he immediately warned that I didn’t know what was done, or maybe it was damaged as a result of the attempts of the owners, and said that maybe anything and it didn’t come working or married. To which he received the answer «it’s all the same.» An interesting start. nine0003

Let’s take a look at the board:

It looks like an ordinary «green»

The power supply has a radiator.

There is m.2, how could it be without it. But SATA3, as often happens, is only one connector. The remaining 5 are SATA2. In principle, such speeds are enough to connect storages in the form of HDDs, but still. In general, it depends on the chipset, maybe 2 SATA3, which one they will send is a mystery. nine0003

There is a WORKING indicator of POST codes. Working in the sense that it shows different numbers, which sometimes coincide with the problem. All the same, all of a sudden, the Chinese came up with something of their own. Although everything should be fine. There is also a beeper with an unpleasant sound, which I sealed.

There are power and reset buttons right on the board. This is very convenient to some extent. In home use, «set and forget» they are not needed. But during overclocking, firmware, etc. will be helpful.

4 slots for DDR3 memory and the ability to work in 4-channel mode. nine0003

Mighty LGA2011 socket.

The processor that was in the Xeon E5-1660 kit, I have the same one on hand. They didn’t give me a cooler. Therefore, we put Zalman Optima 10X.

The board doesn’t start immediately, post 19. I poke the memory in different combinations, it starts up. I boot into LiveCD, I climb to see how many channels are working, the test in Aida64 shows 4, as expected.

I’m leaving for 20 minutes.

I see a BSOD on my return. Maybe with memory? I run memtest and leave, on my return I see that livecd is loaded, which means there was a reboot and it booted from what it had. I turn it off, put another memory. Post 19, then 65 and 67. I put another memory, everything is fine. I start livecd again, see what kind of devices and make screenshots, after 5 minutes it hangs.

I turn off the power, wait a couple of minutes, turn it on, everything is fine, I’m loading. Stood for 30 minutes, everything is fine. Let me think I’ll load it, I start stress types, only percent. It warmed up for about 15 minutes, the temperature is normal, but the feeder is very hot, the finger does not hold for a second, but calmly withstands idle time. I didn’t have time to measure with a pyrometer. The southbridge is just warm.

I climb into the devices again and when I get to the drives I hang. nine0003

I turn off the computer, turn it on. Post 19.

Curtain.

The motherboard did not come out of the stupor anymore.

Searching for information on this post code, led to the fact that the initialization freezes on the south bridge. This is if you believe the native POST codes.

One person was helped by soldering or warming up, I don’t remember already, the socket.

The trouble is most likely with the bridge, because having collected thoughts in a heap, I came to the conclusion that most of the freezes were when pulling drives and usb.
