I'm using an ATI Radeon 5870. Not so hungry I think, but the powermeter can't lie.

I'm using an old 480W PSU from the P4 era. I think that 12V line is really too weak.

With the 6238, Windows 10 won't install. But now it is installed using the 6128, I will try again tomorow with the 6238 and the other ones I have.

Old PSU is not efficent. Propably to much loss and like you said weak 12V line. I would check with low power vga.

Windows 7 or 10 need additional drivers for this board ? Seller doesn't seems to provide any.

Windows 10 doesn't need anything.

I'm currently writing on the system with the ZS200800TCE25 from crazybubba installed. And despite what crazybubba said and what is written on cpu-world identification page, it is not a 12 cores but a 8 cores Sad. And Windows identifies it as a 6128...

For a couple of years now I buy motherboards from ALiExpress to test my ES and non-ES CPUs.

Here's what I currently use:

LGA1356

LiYang X75M v1.0
https://fr.aliexpress.com/item/32870791612.html?spm=a2g0o.productlist.0.0.5043468er86aL7

Most of my B0 ES are working but it seems that v1.1 board offers more compatibility.

Well, wait wait, CPU-World CPUID give me 12 cores !

But benchmark results are not consistent with that. CPU-Z benchmark is identical with the one of 6128 and passmark benchmark results is even lower than the 6128...

Good news it is working ! Please check Windows Task Manager and how many cores are available there ? If only 8 then it is propably BIOS limitation.

OK, well, i restarted the system, and Windows made an update. I went into the bios, there was 12 cores, and no possibility to change. Now, back to Windows and I have my 12 cores !

Great ! 12 cores power from such a cheap CPU Smile When you will be able to get better PSU please test stability with Prime95 Torture Test.

BIOS have an option to increase FSB ?

No hardware issues reported in Hardware Manager in Control Panel ?

Better bargain is a 1356 or 2011 plateform. Here is the bench with the X79 Chinese motherboard + a E5-1428 v2 bought to John for $8

This G34 board have only two memory channels and afaik it can be configured two ways: one channel per die or both channels for one die.
In latter case second die can access memory only through NUMA and it is much slower, it can cripple memory intensitive tests.
Obviously even the first configuration is slower than normal four channel system.

Yes. Common point of most of those motherboards is that there are very few memory slots (exit triple channel or quad channel), and are using cheaper chipsets than the one intended to be used with those cpus.
G34 motherboard is using RD890+SB700 instead of SR5670+SP5100. It is even faking CPU-Z on that point !
X79A motherboard is using a H61 instead of a X79. And so on...

Very interesting. Can you tell us the ES Stepping working on each board ?
