yeah it does on any ethash algo. etchash is ethash variant.

6800 series are more or less at peak of what they can do unless memory timing mod becomes a thing.
You should really be on linux with that VII to get 100 MHs

So the behavior started without any user related changes. the only thing that happened in between was Windows update.

wasn't in miner directory but opencl.dll is present in wndows/system32. I thought this was a normal case?

If I run the miner in admin for msr_tweaks I started getting "NAUGHTY3" as response.  What is this?

It's around 10-12w for just the board.

No you don't enter anything like --eth_config for kawpow algo.

Hive can be flashed onto usb using a flash tool like etcher. Right? It would be plug a USB drive and boot.

we can use Nvidia in headless configuration. System will boot unless you've connected a display cable to the board.
I used it on a mix of AMD and Nvidia card. RTX 3000 series.

It costs $145+$30 DHL shipping.

Also, when I did a search they had these kind of boards since 2015. Maybe the mining boom didn't pick it up in 2017.  The APU is old.

This review is for the All in One motherboard, cpu, ram combo with a dual slot PCIE card footprint.
Introducing REBTECH 8GPU-MB powered by an AMD A6-8500


Full Specs:
CPU/APU               : AMD A6-8500P FP4 SOC , Radeon R5 Embedded Graphics 15W TDP , 1.6Ghz , 1MB L2 Cache , 4 Cores
Memory                : 4GB SO-DIMM DDR3
Storage support     : mSATA SSD, USB Flash Memory stick can be used
Expansion slots      : 8 x PCIex via USB3.0 Connectors
Networking            : LAN RJ45 10/100/1000 Controller
Video cards            : AMD & Nvidia**
Video out               : HDMI 1.4
External I/O           : 1 x USB 2.0, 2 x USB 3.0
Power                    : 12V 6-PIN pcie

Dimensions       L: 250mm, W: 40mm, H: 100mm
OS Support       Windows® 7 32/64 bit , Windows® 8.1 64 bit, Windows® 10 64 bit , Linux, SimpleMining, HiveOS, ethOS, mmpOS
Warranty               30 days

**nVidia video cards will only work without video output from the MB.
Mining RIG output can be seen only via SSH or from simplemining/hiveOS app.

I got this board primarily due to the form factor and low TDP value (~15W or lower)

Additionally, there is no need for pcie 1x to USB adapters.
It eliminates the need for ATX psus if all your GPUs are powered through server PSU.
Could provide better airflow and cable management especially if you've put the GPUs on a wire-shelf.
Costs the same as traditional motherboard, ram, cpu combo these days.



My testing was done on MMPOS (flashed on to a USB drive) which booted just fine out of box.
I did my Nvidia cards with display output both from video card and onboard HDMI slot. Neither method worked.

So the trick is to setup whatever BIOS parameters you'd need to utilize prior to installing any Nvidia cards
In my case there was nothing that I had to change in BIOS. I just plugged 7 AMD gpus. Verified display out from onboard HDMI port.
Turned off the system. Plugged in the Nvidia card and MMPOS just booted up fine. I SSH'd into the machine and was able to mine/configure just fine.

Conclusion
In these times when the prices of PC components are exorbitant, this board is definitely worth it. The only con I see is
the warranty of 30 days in comparison to mainstream desktop parts.

You need to drop core voltage and core clocks considerably. You're just wasting power at he moment. Dial down to 1250-1275 on core with voltage of 725-750mV.

did you enable compute mode?

You'd need to set the overclocking settings using an 3rd party app like overdriventool 0.2.9.  You can setup a bat file to do all the OC and run TRM then.

won't die just caused it used all of memory available.  it might be just more stress on the memory controller or heat.

It's not much different from earlier releases. The updates are for helping out users to understand things better.
As for the 1 MHs gain, it's significant, especially when you combine that with the power savings.

If we restart miner too soon on linux I get "Bind Address already in use" on API port for the stats.

You can "watch" for official releases from the github page.

This is in works.  Also, here's what I use on Radeon VII's

1540 core clocks 995 Mhz on memory 850mV - 84 MHs

How did you arrive at the conclusion it's not thermal throttling?
[/quote]

Cause the core clock drops to 930 mhz as soon as the memory is above +400 . Card temp hovers around 45-50c.

When a card thermal throttles it at least gets high enough to produce heat , my trio x does not even achieve that.

I experienced today my friend xc3 ultra thermal throttling and its not at all how my card behaves . His card hit 99mhs and stayed there for 5 min before throttling and crumbling down to 85 mh while temps were reaching 70C.

Pretty sure its a power limit issue . Some have fixed that by flashing the bios with a different brand bios with higher power limit .

No it's not. You can confirm if it's throttling or not in gpu-z perfcap reason.
The temps that you see are core temperature and ethash doesn't pound much on the core but is hard on memory and GDDR6X runs really hot. Nvidia has the memory temperature monitoring enabled but haven't exposed it to users.  Most likely your card is throttling itself.  Boost the fan speeds up with a custom fan curve or like other person mentioned; point a fan at back of the card.
