Cheap chinese x79 mobos

[alex_stief]

I think it is safe to assume that very few -if any- of the cheap Chinese "X79" motherboards ever had an actual X79 chipset.
They use what ever they can find for cheap, and make it work. X79 is just their catchy marketing term to say "runs LGA2011 CPUs"

 

[Neil Jefferies]

Very unlikely, the easiest way to get the required functionality is to use the chipset. I can locate 1000+ quantities in surplus shops in HK and China pretty easily for way below the original price so it's the easiest way to go - it's still probably the most expensive component on the board even at 10-20 dollars a pop in bulk (you can even get them on eBay for 39.99!). Otherwise, you end up having to either use a more expensive chip or more different chips - which costs in terms of board real estate, layout complexity and supply chain complexity.

In fact, I have a Chinese-made X79 motherboard. (Google Translate is great) I used to test memory and compatibility.
Server memory/desktop memory/plus a conversion slot can also test the laptop's memory.

...I guess technically all of my 2011 motherboards are Chinese-made - Lenovo, SuperMicro, Asus all manufacture in China or Taiwan too!

Thank you @BeTeP.

Asus Hyper M.2 X16 v2 ($57 AMZ) - drawbacks = reports of fully populated card required to use, some nvme slots do not show up on some motherboards.

I just want JBOD carrier functionality so given the title of this thread I think I'll go with the Asus for now and see what happens.

When I purchased the ASUS it ended up being $53 for some reason.

x4x4x4x4 bifurcation works fine in the Jingsha X99.

Maybe a bug in the BIOS. Under the NVME devices menu only the first 4 NVME devices found are displayed. Using the onboard m.2 slot only shows the one in the m.2 slot and only 3 of the 4 samsungs then. However the PCI IIO menu per lane displays all 5 linked up at 4x. Pics showing just the Asus installed with the 4 samsungs.

Need to fire up an OS and see what story that tells now.

all 5 M.2 devices show up in the drive boot menu so that makes me think the nvme device menu only displaying 4 is a limit or a bug.

One other thing I noticed is that using the onboard m.2 slot robs an x4 from the x8 (in x16) slot.
which makes sense ... This motherboard also has qty 2 x1 slots... which I am guessing will also rob from the x8 in x16 slot if you used them. Still enough in the x8 now x4 to run 10Gbe though (I think).

With an m.2 installed you must bifurcate slot 1 to x4x4 in order to get the x8 (phys x16) now x4 to work. windows seems happy as does the MX312A.

Nice! Working on porting coreboot, should resolve BIOS quirks and provide more stability and faster boot times.

Hi e97 and itronin, I just ordered the Jingsha X99 (using the link to Diego at Alibaba) and wanted to thank you both for all the information you guys have provided. I also ordered the E5-2678v3 and look forward to this project. Any tips are appreciated or links to details about your materials, configurations etc. I was hoping to find some OEM case like Dell Precision or even Alienware but no luck yet.

Was about to pull the trigger on an Huananzhi X79-16D with two 10-core Xeons. Then the JCC erratum happened and I changed my mind. Getting a Ryzen X3950 as soon as boards with a passively-cooled X570 are available that are not E-ATX.

 

[FriscoTec]

Has anyone gotten the ALL CORE TURBO trick to work with the Xeon E5-2678v3? I'd of course need a BIOS for the SZMZ X99-8D3 (I did get from Diego so I will request a BIOS from him) also interested in a custom flash logo and haven't played with that in years.
* Okay it works. Just used the tf_tb.rom and V3.efi

anyone got one of these chinese x79 MB with proper S3 sleep implementation?

How're you testing this for 'proper s3' functionality?

 

[wildpig1234]

How're you testing this for 'proper s3' functionality?

1. There should be a setting in bios for S3 sleep
2. Sleep would show up as a choice along with start and shutdown in windows once you install the proper driver for yr graphic card
3. When you choose sleep the computer should enter sleep (s3 means no fan should be running with monitor output off). The computer should come out of sleep and work properly. you should be able to do 10 consecutive manual entry into sleep and awake from sleep without the computer lock up or crash or show a black screen, etc.

For the Runing X79z B10 MB, I found a mention on a russian site that the MSATA need to have all four of the jumpers near it set to 1-2 instead of 2-3 for the MSATA to work. I wonder if those jumper will take away another sata port... guess will have to test that out.

X79Z B10 - китайская материнская плата lga2011: обзор, характеристики, покупка, цены, разгон

X79Z B10 - необычная материнская плата для 2011 сокета из Китая. Обладает 8 слотами для памяти и 8 pci-e (2 x16, 2 x8, 3 x1). Обзор характеристик, разгонного потенциала, цен и способов покупки.

a Russian site also mention a somewhat complicated fix for the S3 sleep:
2. Create a .bat file with the following text:
net start "sppsvc.exe"
rundll32.exe PowrProf.dll, SetSuspendState

Think I will try this on the Runing board...

 

[Jannis Jacobsen]

How "secure" are these chinese motherboards?
Are you sure they dont have anything "extra" in the firmware that can log keyboard inputs etc?

I'm a bit sceptical to random hardware from china were I will input passwords, credit card numbers etc.

[wildpig1234]

there was an article by STH dealing with supermicro boards allegedly having backdoors. Any board can have backdoor. There are no board that are not made in asia. But it's highly unlikely that your credit card info is stolen by backdoor in boards. It s a lot more likely from phishing and malware.

 

[wildpig1234]

that batch file thinggy didn't work for the runing board ;( i guess s3 sleep will only work with the newest chinese boards ;(

 

[kagurazakakotori]

Some of these motherboards actually use H61/Q65/B75 chipsets (Yes Chinese craftsmen have made it possible to use these chipsets with lga2011 CPUs). Stay away from these boards as they have some compatibility issues like not supporting ECC LRDIMMs and/or 12-core CPUs and stability issues.

Some of them even B85 (haswell) chipset now. Luckily memory support and core support does not relate to north bridge anyhow. Sometimes boards are just faulty, and QA of them is bit lower than from Asus for example.

Would be cool if they can make a board supporting v1, v2, and v3 cpu....lol
