1  Alternate cryptocurrencies / Mining (Altcoins) / Questions about 550V Electricity Panel - 100$ Question on: March 10, 2018, 02:47:52 AM
Hi There,

I now have acces to a new warehouse, but the thing is that my incoming electricity is not 240V as i'm used to it, it's 550V....

How can you calculate how many rigs you can plug on that ?
How can I calculate what's the price of my Kw/H ?
I'm not sure to understand the Electricity company explainations:

Quote
Rate G
General rate for small-power customers
Back to base rates

Customers eligible for Rate G
Rate G applies to contracts with no billing demand or with a minimum billing demand of less than 65 kilowatts (kW).

In general, Rate G is advantageous for customers whose power demand does not exceed 50 kW. Approximately 90% of Hydro-Québec business customers are signed up for Rate G.

These explanations have been simplified. For more details about Rate G, consult section 1 of chapter 3 of the Electricity Rates, approved by the Régie de l’énergie.

Structure of Rate G
Billing for Rate G includes the following:

A fixed charge, i.e., an amount you pay for each period in question, even if you consume little or no energy. It is established on a monthly basis, but the amount billed varies slightly from one consumption period to the next based on the number of days in the period.
An amount for the energy in kilowatthours (kWh) consumed during the period in question. Two different prices apply depending on the amount of energy consumed:
a price for the first 15,090 kWh
a lower price for the remaining consumption
An amount for the power in kilowatts (kW) measured during the period in question, if the power demand exceeds 50 kilowatts (kW).
Rate G is a monthly rate, which means the fixed charge, the first-tier consumption limit and the amount billed for power are based on a 30-day period.

In general, the consumption period is about 1 month if there is a charge for billing demand, or about 2 months if there is no charge.

Learn more about your electricity rate

Rate G prices in effect
Fixed charge for a 30-day period, adjusted to the exact number of days in the consumption period in question $12.33
Price of energy
First 15,090 kilowatthours (kWh) 9.78¢/kWh
Remaining consumption 6.88¢/kWh
Price of power
First 50 kilowatts (kW) not billed
Power exceeding 50 kW $17.43/kW
Rates in effect as of April 1, 2017. This table does not replace the Electricity Rates document in any way whatsoever.

How to read your Rate G electricity bill

Switch to another rate
Automatic switch
Hydro-Québec will automatically switch you to Rate M or Rate G-9 if your total consumption is 100,000 kilowatthours (kWh) or more and if, given the rates in effect on April 1 of each year, applying the more advantageous of these rates would yield savings of at least 3% on your electricity bill in comparison to Rate G.

When your minimum billing demand reaches 65 kilowatts (kW), your contract is no longer eligible for Rate G. It automatically switches to Rate M or, if your load factor is less than 30%, to Rate G-9.

Request a switch
If you’ve been billed for power (power demand of 50 kW or more) at least once over the past 12 monthly periods, Rate M may be more advantageous for you.

If the load factor on your bill is usually below 30%, and your power demand is above 65 kW (a billing demand of 15 kW shows up in your consumption history) at least once during the past 12 monthly periods, Rate G-9 may be more advantageous for you.

If you think one of the situations above may apply to you, contact our Business customer services at 1 800 463-9900.

Planning any changes?
If you’re planning to buy new equipment, extend your business hours or enlarge or renovate your facility, your use of electricity could increase and it could then be to your advantage to switch to Rate M or G-9. Don’t hesitate to contact our Business customer services at 1 800 463-9900 for more information.

Other rates or rate options
If you have your own electricity-generating equipment and have a Rate G contract, the following option may be of interest to you.



2  Alternate cryptocurrencies / Mining (Altcoins) / Mixing 570/580 issues - 50$ Reward for solution (ETH/BTC) on: February 12, 2018, 09:37:00 PM
Hi there

I have different models of RX on my rig: RX570 4GB/8GB and some RX580 4GB/8GB of different brand.
All the card are flashed and all off them have been tested individually. (It's a rig of 6 gpu)

When I plug the first GPU, I have to use the AMD Patcher because it shows a warning in the device manager and it's not recognized by the drivers.
I have to do that every-time I add a gpu.
Everytime I add a gpu, all the 570 get back to "warning state" in the device manager.
I'm pluging one gpu, installing the drivers, rebooting, adding one, etc...
The best I've been able to do is 5GPU, sometimes 4 MAX, etc...

Motherboard is Asus-Prime Z270-a and i'm running w10.
I have another rig running with 3 different model of gpus (Total of 6 gpus) and it's working fine without issues.

Thank you very much, If you can help me to solve this, I'll send a 50$ reward to the person with the solution.
3  Alternate cryptocurrencies / Mining (Altcoins) / Problem with Asus Prime Z270-p (REWARD 75$ of BTC) on: February 03, 2018, 08:10:49 PM
Hi There

I have a weird error with my Asus Prime Z270-p....

The rig was running for a while with 6 gpus on it, but yesterday it crashed and at boot it said windows startup was corrupted so i've freshly installed w10.


Now the problem is:

I can get 3 or less gpus running if one of them is connected to the first PCIE16x slot, more then that the bios appear and black screen after
BUT
I can get 5 gpus running IF the first PCIE16x slot is NOT used, more then that the bios appear and black screen after

I've tried multiple combinations of GEN1-2 in the 3 different place of the Mobo BIOS but I can't get it to work.
I've also tried to downgrade the bios mobo to V0812, testing 6 gpus was unsuccessful, I've switched it back to the latest Version and I can't use the first PCIE16x slot....
Also, I've tried different combinations of order for the gpus, they all seems to work fine.

Have any idea? Do you think the Mobo is fried or something ?
Thank you VERY much!


Info Update:
-Clear CMOS: Done multiple times
-Booting with only ONE gpu connected via risers to the first PCIE16x: Working
-Running BIOS version 1002

Hi there,

I'm having troubles with my Gigabyte 990FX-Gaming Rev1.0, I'm not able to get more than 4 gpus to work on it. It was working before but now it doesnt.

I've reinstalled a fresh W10 in it, but when I connect the 5th gpu, I dont get an image anymore on the monitor.

Got any tips for that board?
Thanks!
6  Alternate cryptocurrencies / Mining (Altcoins) / What is your pipeline to OC Gpus after flashing for optimization? on: February 01, 2018, 05:57:41 PM
Hello!

I would like to know what is your way to OC gpus for optimization with OverdriveNTool after you've flashed an amd gpu for Dual-Mining ?

As an exemple, do you start by augmenting the Memory Mhz? And by increment of how much ? Testing it for how much time ?

Exemple of pipeline: Augmenting Memory by 50mhz, testing for 5 minutes each time -> Reducing Core Mhz by 50mhz, testing for 5 minutes each time -> Reducing Core Mv by 50mv untill crash, testing for 5 minutes each time etc....

What is your pipeline to optimize the performance of gpus ?

Thanks for the share!
7  Alternate cryptocurrencies / Mining (Altcoins) / Getting Crazy with this, need help with RX570 4GB MSI Armor OC on: January 31, 2018, 11:52:21 PM
Hello

I've been trying again and again to make my rig of 6x RX570 4GB MSI Armor OC to run but there's nothing I'm able to do with it to make it stable. The only thing I get is blue screen again and again (VIDEO_TDR_FAILURE)

Do you guys have any .rom I could use ?
I've been using the Anoraks one memshift1500 for both Hynix and Elpida, knowing I have both of them in my rig.
I had to use -f command in ATI because the ssid wasnt matching.

Any .rom I could use or OC settings with OverdriveNTool ?
This rig is getting me crazy...

If you guys have any tips, I'll be very happy.
Thanks
8  Alternate cryptocurrencies / Mining (Altcoins) / Can't get 5GPU with Asus Prime z270-p (FIXED) on: January 16, 2018, 03:34:19 PM
Hello !

I actually have a asus prime z270-p and I'm not able to make it work with 5 or + gpus.
When I connect the fifth card, I see the Mobo logo but screen stays black after.
I'm running on w10, this is my third asus prime z270-p and I didnt had any issues with the two others.

The bios is updated to the latest version
-4G enabled
-Pci speed set to GEN 1 (tried with GEN2 but doesnt work)
-Hd audio controller is turn off
-Fast boot disabled

Also, When i disconect the fifth card and reboot, w10 is showing correctly and the drivers are working

My monitor is connected via the hdmi of the mobo.

Thank you!

EDIT: I've tried different pcie port and it doesnt make a difference, I can get 4 gpus working with any pcie port order used.
9  Alternate cryptocurrencies / Mining (Altcoins) / GPU optimization process - Sapphire Pulse RX580 4GB - 11265-09-20G on: January 11, 2018, 06:04:49 PM
Hi Everyone!

I just bought a big bunch of gpus of the same model, lucky me they all have the same memory brand (Elpida).
I'll share with you my optimization process of the bios and OC settings, my way to work, etc...
My goal here is to get peoples tips to optimize further and also help people in the futur who would want help with this model of GPU.
I might also post the same process for other model of GPU later on.


GPU model: Sapphire Pulse RX580 4GB
SKU: 11265-09-20G

Rig set-up
OS: W10 Pro Version 1607
Motherboard: Asus Prime Z270-A
GPU#: 7 Gpus
RAM: 4GB
PSU: 2x 750W Gold

Tools i'm using:
AtiFlash
OverdriveNTool
PolarisBiosEditor
HwInfo


My goal with these gpu is to hit a STABLE hashrate of 28.4MH/s ETH minimum + maximum Mh/s DCR with a power drawing as low as possible.
I want to create a global rom and OC settings I can apply on all gpu without tweaking them individually for the moment.


----------

First settings for RX580 Pulse Sapphire 4GB ELPIDA:
AMD Driver Version: 17.12.2 (Blockchain)
Miner Version: Claymore 10.2
Eth Mining only

Miner settings related to OC:
-Ethi 8

BIOS modifications:
Put the 1500 time strap into the higher one without touching anything else in the bios, Flashed the gpu with it.

OC settings:

Core Clock
P0: 300 MHz - 750 mV
P1: 600 MHz - 769 mV
P2: 900 MHz - 887 mV
P3: 1145 MHz - 975 mV
P4: 1200 MHz - 975 mV
P5: 1200 MHz - 975 mV
P6: 1200 MHz - 975 mV
P7: 1200 MHz - 975 mV

GPU Clock:
P0: 300 MHz - 750 mV
P1: 1000 MHz - 825 mV
P2: 1980 MHz - 975 mV

Fan:
Minimum (rpm): 1500
Maximum (rpm): 3500
Target Temp. (*C): 45
Acoustic Limit (MHz): 4000

Power:
Max. Temp. (*C): 84
Power Target (%): 25

Results:
95% of the gpus handle these settings correctly without any crash, BUT some of them need a reduced Memory (P2) from 1980 MHz to 1940 MHz or they crash at the dag creation. (I'm not using -lidag)
Power Drawing: +/- 1140W (Still too high)
Average hashrate: 29.4 Mh/s

Issues: Some cards are throttling to +/- 26 mh/s and get back to 29.4mh/s at the next stats refresh.

Errors I'm getting:
1- Can't see temperature and fan speed in Claymore even when I hit the "S" key. (Fixed by upgrading to Claymore 10.3)
2- Sometime I see an error: "Temperature Thread Hanging, need to restart miner." (Fixed by upgrading to Claymore 10.3)


----------

Second settings for RX580 Pulse Sapphire 4GB ELPIDA:
AMD Driver Version: 17.12.2 (Blockchain)
Miner Version: Claymore 10.3
Dual Mining (ETH + DCR)

Miner settings related to OC:
-Ethi 8
-Dcri 20

BIOS modifications:
Put the 1500 time strap into the higher one without touching anything else in the bios, Flashed the gpu with it.

OC settings:

Core Clock
P0: 300 MHz - 750 mV
P1: 600 MHz - 769 mV
P2: 1300 MHz - 875 mV
P3: 1300 MHz - 875 mV
P4: 1300 MHz - 875 mV
P5: 1300 MHz - 875 mV
P6: 1300 MHz - 875 mV
P7: 1300 MHz - 875 mV

GPU Clock:
P0: 300 MHz - 750 mV
P1: 1000 MHz - 825 mV
P2: 2000 MHz - 975 mV

Fan:
Minimum (rpm): 1500
Maximum (rpm): 3500
Target Temp. (*C): 55
Acoustic Limit (MHz): 4000

Power:
Max. Temp. (*C): 80
Power Target (%): -25

Results:
Power Drawing: +/- 1350W (Still too high)
Average hashrate: 29.4 Mh/s ETH + 585 Mh/s DCR



----------


I'll keep you guys updated of the process, don't be shy to give any constructive comments.
Cheers!










10  Alternate cryptocurrencies / Mining (Altcoins) / Asus Prime Z270-A Error - No image with 2+ GPU on: January 08, 2018, 02:42:10 PM
Hi Everyone!

I have an error with my Asus Prime Z270-a, it's the first time i encounter this problem, all my other rigs have been fine.
I connect one gpu via riser to the first pcie16x and my monitor is on the onboard hdmi port. I'm able to install windows, install the drivers for Rx580. I reboot the rig, everything is fine.
When I connect a second GPU via riser, I'm not able to get image via the onboard port. I see the mobo boot screen logo, but after that, my monitor go to sleep mode and nothing happens.
If I disconect the second gpu and only run with one gpu for booting, the image come back on my monitor and the amd drivers are still there and working correctly.

The things i've changed in the mobo bios are:
Primary Display: IGFX
IGPU Multi-Monitor: Disabled
Pcie speed: Auto
Hd Audio Controller: Disabled
Fast Boot: Enabled
4G: Enabled

GPU Bios are stocks

Does anyone have an idea on how to solve this issue ?
Thank you!

12  Alternate cryptocurrencies / Mining (Altcoins) / Claymore mining problem - 50$ BTC reward on: December 24, 2017, 05:06:39 PM
Hi there!

I have a rig of 7x580, Everything was mining fine even after reboots untill I've shutted it down, removed the monitor cable and booted it...
Now the problem is: The gpu which had the monitor pluged in, is either not mining at all or hanging in claymore after a couple seconds.

As soon as I unplug the monitor, the GPU# stop mining, as soon as I replug it the GPU start mining...

The rig has been mining for 24h with a monitor, but GPU#0 is not able to mine without a monitor, or it's a 1-2mh/s

Thanks!
