2  Other / Off-topic / building Sgminer. configure: error: Missing required libcurl dev >= 7.25.0 on: November 16, 2017, 08:30:29 PM
 I am not able to get libcurl to be recognized by Mingw32.

Here are the directions. However, they are outdated.

Has anyone built sgminer with the following directions successfully? https://github.com/sgminer-dev/sgminer/blob/master/doc/windows-build.txt

How did you get libcurl to work?

**************************************************************************************

* Install libcurl                                                                    *

**************************************************************************************

Go to this url ==> http://curl.haxx.se/download.html#Win32

At the section where it says "Win32 - Generic", Click on the link that indicates

Win32 2000.XP 7.xx.x libcurl SSL and download it.

Extract the files that are in the zip (bin, include, and lib) to their respective

locations in MinGW (\MinGW\bin, \MinGW\include, and \MinGW\lib).

Edit the file \MinGW\lib\pkgconfig\libcurl.pc and search for the line that ends

with "-lcurl", and make it say "-lcurl -lcurldll".

i think the fee is given to the miner in the form of a brand new coin or a percentage of one.

I sent this from the Gemini exchange wallet.

I am testing etherium out soon. hopefully by the end of the week.



4  Bitcoin / Bitcoin Discussion / Sent Bitcoin but no fee was docked. transaction block states there was 1 though on: September 25, 2017, 12:21:54 AM
Here is the transaction block: https://insight.bitpay.com/tx/b683ed68988af0fc649fc542414db0c97cbf8dd4a42d7258b7ec62bf647e039f

I sent the following amount, which i shown at the bottom as output or sent: 0.024638 BTC (S)


That same amount arrived to the other wallet. I am guessing that the current protocol is to give the miner in a fee in the form of a new coin if its not docked from the amount sent.


Any input is appreciated. I am trying to figure out which is more efficient for me to send different amounts. Etherum or Bitcoin. and this was fantastic to see i just do not understand. I wonder if it will remain this way. I have read in the end it will dock fees from the actual amount sent. I thought it already did. but it seems I am wrong.

is Cryptopia the cheapest way to get B3? it seems to be a  20 percent fee on the exchange when i got to buy it? Is that what everyone is paying?

EDIT: it is not 20 percent. it is .20 percent. Please excuse my horrible error.

Again, not 20 percent but .2 percent.

I have downloaded the B3 wallet and look forward to try out staking. however, in downloading other staking wallets I see some type of status that it is syncing with the network, yet this wallet does not show that.

This is normal correct? it will sync after some time? even though there is not message stating it is doing so. Please see here:
8  Alternate cryptocurrencies / Mining (Altcoins) / server PSU GPU breakout board. Why would one have a capacitor and another not on: September 13, 2017, 10:06:46 PM
I am looking at using either of these parts to connect to a server power supply. I realize a capacitor helps to regulate voltage. Why would each of these parts that have similar function not both have a capacitor. That makes me think that a capacitor is not needed.Could it possibly be due to inductance. But it still does not answer why one has and one does not.

Any input is appreciated:

With capacitor: http://www.ebay.com/itm/DPS1200FB-A-Power-Supply-Breakout-Adapter-Board-10-PCIE-Cable-fr-Ethereum-Mining-/322705408187?hash=item4b22bdc0bb:g:sS4AAOSwcQlZqoHk

Without Capacitor:

Risers I am using (with four capacitors): https://www.amazon.com/gp/product/B01MU51491/ref=oh_aui_detailpage_o04_s01?ie=UTF8&psc=1

If i have capacitors on the actual riser. I would think that I would be okay not having them on the breakout board.

If one is recommended over the other i would appreciate any input.

 
9  Alternate cryptocurrencies / Mining (Altcoins) / Re: Unable to mod memory clock bios above 2200 on Hynix XFX or Gigabyte card. on: September 07, 2017, 05:34:45 PM
I mean I pull up GPU-Z and it is still at 2200 MHZ, even with 2300 in the bios in both place under "Memory" and "PowerPlay". The memory strap stops at 2250. I doubt it. I am sure that memory straps stop there on Samsung memory as well. but could be wrong. have not checked this yet.  Could that be the issue?

10  Alternate cryptocurrencies / Mining (Altcoins) / Unable to mod memory clock bios above 2200 on Hynix XFX or Gigabyte card. on: September 07, 2017, 05:21:56 PM
Brand: Gigabyte and XFX
Model: GIGABYTE AORUS Radeon RX 580 8Gb and XFX Radeon RX 580  8Gb
Memory size: 8 GB
Memory manufacturer: Hynix
Custom settings: Strap that I am using to mod both bios's in the following slots: 2:1750,2: 2000, 2:2250

777000000000000022AA1C00B56A6D46C0551017BE8E060C006AE6000C081420EA8900AB0300000 01B162C31C0313F17

Funny enough I googled this strap and i think it is is an original strap from Micron memory. i think it was the 2:1750 original.

Sidenotes: I saw that some individuals can get there memory clock to 2300 megahertz. These two gpus's will not go above 2200. I have modified both the "PowerPlay" and "Memory" section of the Polaris Bios Editor with 2300 at the max frequency(PowerPlay) and third frequency under memory with 2300 but still nothing.

Is this a hynix thing or am i doing something wrong. The two individuals I saw doing this had Samsung memory.

One post showing the 2300 mem clock: https://forum.ethereum.org/discussion/12529/msi-rx580-8g-28mh-without-bios-mod

Any input is appreciated.

12  Alternate cryptocurrencies / Mining (Altcoins) / Powered vs non powered 1 to 4 PCI-E mulitplier Riser Adapter Card on: September 06, 2017, 01:49:19 PM
Hi,

Which riser is better for someone looking to hook the most gpu's up to a system.

A.) powered 1 to 4 PCI-E Splitter: https://www.amazon.com/Cablecc-Express-Switch-Multiplier-Splitter/dp/B073QNW3L9/ref=sr_1_2?s=electronics&ie=UTF8&qid=1504685701&sr=1-2&keywords=1+to+3+PCI+Express+1X+Slots+Riser+Card


B.) Non-powered 1 to 4 PCI-E Splitter: https://www.amazon.com/gp/product/B073W9KCFC/ref=ox_sc_act_title_10?smid=A3JV1FMRJ9GCIF&psc=1


The non-powered riser has much better reviews but the powered risers from what i have read would be much better for the motherboard and all components involved. The actual risers that i am attaching to the multiplier are powered with six pin cables. But what would be best for the 1 to 4 multiplier riser card. Or will either work? Using Windows 10 if it helps

Thanks

I am using this kind of risers x16 to x1 https://www.amazon.com/Onvian-Mining-Dedicated-Graphics-Supply/dp/B01MU51491/ref=pd_sim_147_6?_encoding=UTF8&psc=1&refRID=863P3M3YTHMTG34STFK8
and I hooked monitor to one of the card witch is connected to this riser. Using PC for normal work with any poblem, if card is runing on x1.

Do you use any PCI-e Express 1x to 4 Port splitters. If so, have you had better luck with powered vs non-powered?

Great input. for some reason I was under the impression that this type of riser could not be used on the dedicated GPU for display functionality. Thank you for clearing it up that it is not an issue. i am going to start out with three of these risers in each slot then use the 1 to 4 pci expansion slots and see how it goes.
15  Alternate cryptocurrencies / Mining (Altcoins) / Re: Powered GPU riser cable for GPU that supports monitor to rig? on: September 06, 2017, 08:37:38 AM
Error from above  Shocked. The powered 4 in 1 PCI-E Riser Adapter Board (https://www.amazon.com/Cablecc-Express-Switch-Multiplier-Splitter/dp/B073QNW3L9/ref=sr_1_2?s=electronics&ie=UTF8&qid=1504685701&sr=1-2&keywords=1+to+3+PCI+Express+1X+Slots+Riser+Card  ) only has a 4 pin power plug (not 6 pin), which I assume to be a molex. In that case I will be using the sata cable to power this. Wanted to correct this from above.

Would it be horrible if I plugged both a sata cable in and a molex cable in at the same time to power the  4 in 1 PCI-E Riser Adapter Board . is that a completely ignorant move? I assume so but appreciate knowing why at least.


 
16  Alternate cryptocurrencies / Mining (Altcoins) / Re: Powered GPU riser cable for GPU that supports monitor to rig? on: September 06, 2017, 08:27:14 AM
I use it for basic things like web browsing, email, and the occasional c++ compiling. But not games, so nothing to GPU intensive. But i do notice that when i have more than one youtube tab open the hash rate can go down from 30 to 29, 28 sometimes and even 24 sometimes.

I think I am going with the Powered riser cable: https://www.amazon.com/gp/product/B01NAE4O7I/ref=ox_sc_act_title_1?smid=AFM4QEJU7QLZR&psc=1


a few other questions if I may. Is it a bad idea to want to get 8 GPU's on a three PCI slot motherboard? If I use powered risers for each of them and a powered 4 in 1 PCI-E Riser Adapter Board. is that really that bad of an idea?


Which 4 in 1 PCI-E Riser Adapter Board would be better. I assume powered but never hurts to ask as I realize I have much to learn.

The non-powered 4 in 1 PCI-E Riser Adapter Board. Has excellent reveiws. Again, it is not powered but the risers i use will be powered: https://www.amazon.com/gp/product/B073W9KCFC/ref=ox_sc_act_title_8?smid=A3JV1FMRJ9GCIF&psc=1

Here is a powered 4 in 1 PCI-E Riser Adapter Board. Wouldn't this be a better alternative than its non-powered counterpart. It bothers me a bit that all the data from the 4 pci slots is going through 1 usb cable but I assume it should not be an issue. I will use the 6 pin power plug on this  and plug straight into the power supply: https://www.amazon.com/Cablecc-Express-Switch-Multiplier-Splitter/dp/B073QNW3L9/ref=sr_1_2?s=electronics&ie=UTF8&qid=1504685701&sr=1-2&keywords=1+to+3+PCI+Express+1X+Slots+Riser+Card 


Thanks, look forwarding to maxing out my motherboard.
17  Alternate cryptocurrencies / Mining (Altcoins) / Powered GPU riser cable for GPU that supports monitor to rig? on: September 05, 2017, 11:38:22 PM
Hello,

I am at a basic bottleneck as to how to plug in my monitor to the rig. I have this motherboard: GIGABYTE GA-B250M-DS3H LGA1151

 My motherboard has a total of three PCI slots: 1 x PCI Express x16 slot (long)  2 x PCI Express x1 slots(short)

I am hoping to get fit more than three gpus on this motherboard but in order to do this. I need a cable riser for the 1 x  PCI Express x16 slot. Because the GPU covers up both of risers or one other riser depending on which gpu i install. I will also be plugging my monitor into the the GPU that utilizes this slot x16 slot. 

Which cable riser is better for a gpu that will be pushing signal to my monitor. Powered vs non-powered riser cable:

A.) Powered riser cable: https://www.amazon.com/gp/product/B01NAE4O7I/ref=ox_sc_act_title_1?smid=AFM4QEJU7QLZR&psc=1


B.) Non-powered riser cable: https://www.amazon.com/EZDIY-Express-Flexible-Extension-Card-25cm/dp/B01NH0GW7Z/ref=sr_1_3?s=electronics&ie=UTF8&qid=1504654154&sr=1-3&keywords=gpu+riser+cable


I have read that a powered riser cable is better. Because it allows for the GPU to act as if it were connected to the actual motherboard. and the capacitor gives it space as the voltage goes up and down. Is this the safest bet if I am going to be plugging my screen into this GPU. Will this riser shorten the life of my GPU? Are there any better alternatives.

Any input on this is appreciated. I am definitely not an electronics engineer but know a little about voltage and i think the power riser would be better with the capacitor.

Has anyone else tried this or had any experience with plugging there monitor directly into one of the GPU's on there rig?
