ASUS B250 MINING EXPERT bios 403 (2017/12/15) released?

[Permonik]

I'm not sure but this bios could be related to meltdown, spectre, they said about stability, have my own doubts.

You have to be right, I think the same thing, because of the words "cpu microcode".

[Neo-Geo]

Neo,

Why Kabby Lake i5 7400T? Celeron is enough.

Another miner that considers Celeron a fail for 8 GPU builds:

any cpu is a fail if using more than 90% 24/7, as long as it below 90% is all fine.

[Raziel666]

I have been using this mobo for the last couple of months.

I had no problems with 6 GTX 1070 GPUs. I bought another 3 of the same, and I could only make it work with 8.

I updated BIOS to 0403 and tried to install the 9th, but the hashrate of *all* GPUs dropped to half. Went back to 8 and it works smoothly.

I updated BIOS to 1001 today but the 9th card isn't recognized at all in the BIOS screen. Anybody has tried with more than 8 cards and succeeded?

[wtfonly16]

more then 8 nvidia cards is always a shitstorm

13 amd cards always worked, just plug n play with latest drivers (compute mode).

The "Meltdown" and "Spectre" vulnerabilities are a CPU issue, NOT a BIOS issue.

I'm fairly certain that the BIOS can't work around the issue - DEFINITELY it can't for LINUX as LINUX doesn't USE the BIOS after a very early part of the boot process.

[Metroid]

The "Meltdown" and "Spectre" vulnerabilities are a CPU issue, NOT a BIOS issue.

It seems the fix Intel released needs a bios update to fully work, you can install only the fix but the bug will still be present, The fix will only work fully with a bios update.

"Since publishing the Meltdown benchmark we now have access to BIOS updates that deliver a microcode update which will mitigate the Spectre flaw on Intel’s latest Z370 platform. "

"Following up to our initial testing of the Meltdown patch for Windows 10, today we're looking deeper into the matter by testing a patched desktop system, by addressing the two now famous security flaws, Meltdown and Spectre, by applying the OS-level patch and a firmware update, more precisely a motherboard BIOS update."

[QuintLeo]

The bug is STILL PRESENT even with the "fix" installed, the "fix" is a work-around to AVOID the bug.

 A BIOS upgrade might be needed for Windows since Windows continues to use BIOS functions while it's running, but it's not going to do ANYTHING for LINUX since LINUX does not USE the BIOS for anything past very early initial boot steps, while the bug doesn't start cropping up 'till a much later stage.

 I'm really not sure WHY a BIOS update would be needed though, or how it would work to do anything about working around the bug involved.

[wtfonly16]

a bios update AND os patch is needed on any affected platforms to fix the "Meltdown" and "Spectre" bug.

I am running BIOS 1001 and 12 GTX 1070ti SC Hybrids on the Asus Mining Expert no problem, using two 110 volt power supplies, one 1600 and one 1000 watt both titanium EVGA, GPU's are staggered throughout the three channel banks, I did not limit them to the first two although I am only using two power supplies, in addition I am not plugging any Molex into the 3 AUX channel bank plugins,

 running SMOS boot from USB, with clocks set to 200 core, 1400 memory, 130 watt, drawing a total of 1750 watt at the wall, including all cards and Mobo, trying to stay below 1800 watt due to the smart plug stating it will only pass 15 amp, and I believe going over that ruined one of them for me, and I really like the utility of the smart plug when I am away from home,

 That article doesn't even mention BIOS at all.
 Do at least READ an article before you attribute things to it that are not there.

 Hint - LINUX "kernel" is NOT a BIOS on a motherboard.
 It's the core of the Operating System itself - kind of like DOS used to be in the Windows 3.x/Windows 95 days.

[wtfonly16]

nop wrong u need bios update for cpu fixed on linuxed.

 WHY would you need to update a BIOS that is NOT IN USE AT ALL by the time these bugs CAN be invoked?

[wtfonly16]

bios used by all systeme it caputer.

Thanks for your input, greatly appreciated!

Can you tell us what CPU/RAM you are using with the 12-GPU combo?

It's so wrong....

[Bigdrago]

I think it never will be support 19 normal gpus.
Amd have never said that.
You have to combine it with p106 or p104 which normal people cant buy.

^^This

I don't recall Asus ever said the motherboard would support 19 regular cards. That was just wishful thinking from those that bought the board by taking the driver update Asus referred to for removing the previous 8 card limit to meaning they could use all regular cards with the board. Although Asus did a bad job of making the limitations of the board clear, all the literature said you needed to use mining cards for more than 11 AMD GPU's.

[Bigdrago]

From Asus site:

B250 Mining Expert lets you run up to 19* NVIDIA or AMD GPUs in parallel to max out your megahash rates!

* B250 Mining Expert currently supports a total of up to eight NVIDIA and AMD GPUs. An unlimited number of GPUs will be supported following a driver update that is planned for Q4 2017.

And then the driver update came:
https://www.asus.com/us/support/FAQ/1034921

Based on the new driver updated from AMD, ASUS proudly announces that B250 MINING EXPERT supports 19x GPU for mining. Comparing with competitors, B250 MINING EXPERT is the world’s 1st MB to support up to 19x GPU.


There is no info about a future bios update that allows people having 19 normal gpu. In my country only business is allowed to buy p106 or p104 in minimum quantity of 100pcs and 3 month warranty.

 Normal people CAN buy the P106 - they have been listed on NewEgg and Amazon - they're just in very short supply due to high demand and LOW production.

 P104 as far as I know is only just hitting production, and is not widely available yet - it remains to be seen what the production levels of THAT GPU get to.
