For those here who are using HiveOS I recommend that you do a reinstall with the 0.5-45 Image and not just do an update.

https://hiveos.farm/install

0.5-45 IMAGE RELEASE 2018-04-19

    Logs are OFF by default
    Linux 4.13 kernel
    Installed ROCm with AMD driver to support Vega
    Configs partition is now NTFS
    Intel's E1000E updated network driver by default

0.5-45 2018-04-17

    NEW: cpuminer-opt
    ethminer 0.14 and 0.15 in the box, version can be selected in the wallet
    amdmeminfo updated

The image uses Linux 4.13 kernel and if you just do the update you will still be on the 4.10 kernel.

On thing I noticed is that on the Linux 4.13 "mpstat -P ALL" now reports the 32 cores on my 4x 8837's correctly whereas Linux 4.10 reported 40 cores with 2-dummy per processor. With 4.10 I couldn't do a custom XMR-Stak CPU configuration now with the Linux 4.13 kernel I can.

Try clearing the NVRAM by changing jumper position on the board. 

* Locate the 3-pin CMOS jumper (CLR CMOS) on the motherboard
* Remove the jumper plug from pins 1 and 2
* Place the jumper plug on pins 2 and 3 and wait approximately 5 seconds
* Replace the jumper plug on pins 1 and 2

Are you running both PSUs or did you remove one like I did?  Maybe try swapping PSU to the other bay or even have both PSUs installed and plugged in.

Another thing to try is resetting BIOS to defaults in the BIOS itself.

I'll do what I can to help you trouble shoot even though you won't take my phone calls!

I have now also tried this from the link :

" I have to go into the BIOS and switch the performance settings from Max Performance to something else, then back. After that, the server performs at lightning speed again. "

Tried on two systems so far -- zero effect.

So... I'm kind of stumped.

So... I have tried on 5 systems so far to power off, unplug AC power, AND unplug the CMOS battery -- leave them unplugged long enough to clean out the system with some air. Re-assemble... and start mining. They are all STILL doing only 1600 H/S vs. 2000 H/S before the power flicker.

I have a set of spare 6276s I will sell.  They will do ~950H/s.

Mine has the 6220s. Sounds like I need a processor upgrade...

Cranking out 1050 on a pair of 6380s on a 385...

So with Monero back up again I decided to fire up my DL385 and give it another try. Put new XMR-Stak on it, configged and fired up. Still getting 660hs. This is stock with no GPUs in it.

Has anyone out there achieved a better rate than this?

Guess i have to give HiveOS a second chance then

Actually HiveOS and the HP's work GREAT.  Currently have 2 running 9 cards each.

It's HiveOS and the Dell R815's that DOESN'T and that's just a NIC driver issue.

That is a problem with the HP server series like the G7 which are a bit old so HiveOS maybe does not have the best support for them. I will also blame HP or any other old server like Dell as I have tested HiveOS with 12 RX 580 cards in ASUS B250 Pro Mining and they worked out of the box perfectly without problems with a great hashrate of 360 Mhs.

The strong Xeon processors are good to mine Bytecoin or Monero.

"I have probably close to 40,000 cells assembled in my diy powerwall to date that ive never purchased... "

Thats seriously impressive man!

Try to source them refurbished or on ebay with bad batteries. I bought 3 from ebay that were server based UPS that just needed new batteries and i picked them up off amazon for a few dollars each, i even went to my local thrift stores and picked up a handful of them for a few dollars and half of them even worked, just needed fresh batteries. The ones i got from local thrift stores i built custom lithium batteries from 18650 cells, i have been collecting thousands of them over time because i was planning to build a DIY tesla powerwall with them along with build battery packs for my Catrike bicycle that i converted to electric assist, i get them free from thrift stores, hardware stores from the recycle bin just ask the store managers, and colleges. The most i got from thrift stores because when someone donates a laptio they cant resell it, so it gets scrapped and disassembled and they pay for someone to take the batteries away.

This is some of the batteries i got last month from going around and asking politely from many locations and picking up some from locations that told me they would place them to the side for me...


Here are some cells im still slowly testing out, i bought 4 tester/chargers units a while back that allows me to test 16 cells at a time, so its only time to test them, i put them on the test and forget about them really and come back when i remember about them, write the capacity on the side of the cell and move on, i store them in bins based on the capacity so my wall cells i assemble have the highest capacity cells. I have probably close to 40,000 cells assembled in my diy powerwall to date that ive never purchased...

The Dells seem to be exhibiting the same trait as when you leave the cover off and they throttle.

I just had two power outages and multiple flickers the last few weeks and I haven't encountered the throttling yet.  I would totally remove power from them for a minute and if that doesn't do it, pull the cmos battery w/ the power out and wait a minute.  That SHOULD do it but you'll have to reconfigure the BIOS to your liking.

I am going to build a 30kwh battery backup system.  I just want enough juice to run everything for an hour.

In regards to 4 GPUs on the 580s, I'll give Windows another shot just for luls but honestly, Hive is so superior and easy it's really not even worth it.  They've been rock solid since I've got them going.

i have geothermal heating/cooling in my house. uses 2000 feet (4x500 foot loops) of pex buried 5 feet down in the back yard and its connected to a 3.5 ton heat pump. system is around 6 years old

the ground loop is driven by two of these pumps in series:

https://www.pexuniverse.com/grundfos-up26-99f-circulator-pump-52722355

but mine say 230v not 120v. but thats the model UR 26 99F

they dont run 24/7 year round but in super cold weather (say like -15F at night to 15F in the day)  the system runs 24/7 for days, switching between high and low power modes.

maybe look into something like that? they look like they are continuous duty but maybe write them and see if its 24/7/365 rated?

Imminent Hard Fork and Network Attack
Intense Coin experienced an attack to its blockchain on April 15, 2018. In this post we will describe the attack, the implications and our plan for resolution.

I know that some people here were mining this coin so I posted this.

USB WiFi may be an option.


I have given up on Power play tables and just use the Adrenalin 18.3.4 driver and Wattman with these settings for my Vega 56's:

------------------------------------------------

Core:
P6: 1397 MHz, 950 mv, Min State
P7: 1427 MHz, 1000 mv, Max State

Mem:
P3: 935 MHz Min/Max State, 900 mv

Fan: Min: 3000 RPM, Target: 4900

Temp: Max: 70, Target 60

Power Limit 0

1935 H/s Using 135 Watts

------------------------------------------------

My Vega 56's are PowerColor branded and 935 MHz was the highest I could run at. You may be able to squeeze out the extra 10 MHz and run at 945 MHz

I am using Cast_XMR as I have found that it produces very high stable Hashes. It is also very well maintained. A new version was just released yesterday.

Check ebay for UPS that would match your input power. You might be able to get a UPS large enough to place it before your distribution panel. I've seen them floating around in the 50kW->100kW range. You also don't really need a UPS, just the auto voltage regulator that most UPS have built in. With the AVR it should keep voltage constant until there is no more power and go to 0 completely preventing over voltage and under voltage situations.

One of the responses in that thread... Seems like it'd be the fastest solution in your case.

I was about to pull the trigger before all the coins fell off a cliff in value, hah...

I am pricing out a full set of UPS units, though, through some distributors... since I'll need 100+ of them. Gonna just have to suck it up I suppose!
