Topic: best mother board for mining (Read 2638 times)

You mentioned that earliest cgminer doesn't support correct number of chips that are on the blade.

I've found that most recent one that does:
https://bitcointalksearch.org/topic/m.6261888

I understand I need some other thing as seen below for rasbperry I think:

getting and using GIT:

above code, is --disable-gpu can be left out?
I simply want to mine on raspberry PI 2 (without display)
What I mean is accessing PI with putty.
I know how to use putty based on enough information

Using cgminer:

According to README.md of cgminer, we see GC3355-specific options can be specified via --gridseed-options:
The default number of chips is 5 and since this miner support 40 chips per blade, I think the above setting is correct!

can you confirm what I provided so far should work on raspberry PI 2?

Not if you're mining ether...

I checked latest version of cgminer 4.9.2
https://bitcointalksearch.org/topic/m.12269796

Apparent;y no altcoin support in master cgminer
After looking at readme and cannot find scrypt support neither

Can you explain that?

Would be great knowing which version that support gridspeed device though!

You can mine with both GPU and Gridseeds on the same machine.
 (I did this with a couple of Radions mining Darkcoin (X11) and up to 3x Gridseed 80 units (6 "blades") mining Lightcoin on the same Linux box for a while).

 I WILL say that Linux was more reliable on running multiple blades, but if you have a Windows machine you're not running much of anything else on it works fairly well.

 You have to run a seperate instances of cgminer, one for whatever you are GPU mining and one to run the Gridseeds.
 You would DEFINITELY have to run seperate cgminer instances for each class of coins (by algorythm, Scrypt/X11/X13/etc.).

 To the best of my knowlage nothing BUT cgminer ever supported Gridseeds, but since I had cgminer working I didn't really bother looking into anything else after I got it working.

 Any machine that can run cgminer AND has at least one USB port can run Gridseeds. Not sure I'd do it on a laptop as I don't trust laptops to not overheat when running 24/7 but should work OK if you have good enough cooling on the laptop.

I live on a basement apartment and I have no problems with heat.

I few questions about miner softwares:
bfgminer and cgminer

bfgminer:
According bitcointalk we read the following
- radeon driver is disable by default
- CPU as well (Not included in window built)

It possible to mine via radeon including with gridseed at same time?
We mine multiple coins?
It would be great to know command setting to use script and to truly recognize two blades

cgminer:
There too many reports seems say it has problems recognize two blades for me consider.

Assume I get gridseed devices:
1) two blade for a computer
2) other one for another computer and a laptop.

2nd option, will allow connecting a blade to a windows PC and other on laptop (That's possible right)?
Shouldn't damage laptop, correct?

Each "blade" runs about 2.5 MH/s at the "stock" 750 Mhz clock setting, but I recommend downclocking them a little unless you have a COLD room to put them in.

 I'm pulling in a hair under .05 Litecoin/day right now per blade, plus a few Dogecoin occasionally via my pool's Merged Mining.

 I have run up to 6 blades on one machine with one cgminer, if you had enough of them with hubs I've read you can run up to 20 per cgminer.

Ok, now I see!

I was confuse in term of input and output on gridseed device!
I see in order to use full mh we need using two blades with 2 power supplies!


Ah, so both blade can be run on same operating systems!

How coins are you earning in 24 hours for example? I'm just curious!

 Probably a good setup for X11 or such, but it's gonna LOSE money hand-over-fist for Scrypt or SHA256.

 I do agree that the Maxwell NVidia cards are the way to go for cryptomining on GPU-viable coins now.

 

Do not engage in this nonsense, buy Asrock PRO BTC + 6x GTX750Ti / 950! / 960/970 and dig safely. After the NVidia Maxwell, farm on Radeon no longer relevant.

I have run my Gridseeds on a windows system, and a Linux system. The Pi is commonly used to run a small Linux system, but I already had existing LINUX machines around so I just used one of those.

Ok, let's see
1) Windows PC
2) Raspberry Pi

So gridseed can run on either system right?

can anyone help me out which computer hardware is good for minning 

The Gridseed 80 actually is 2 "blades" in one device, one USB port per "blade" is needed.

 Power is provided via a "barrel" type connector, +12V - you can do this from a computer-type power supply, or a 12V "brick" type.

 Raspberry Pi does NOT provide power - it's a small computer you can use to run the blades with.

 There is a specific cgminer that is set up to run these, or check github for the source - I don't have a url handy. You need one of the versions (preferably the most recent) that specifically says it supports Gridseed devices. There was an earlier Gridseed "orb" that older cgminer "gridseed support" versions worked with, also works with the blade but doesn't report the hashrate correctly and might not support the correct number of chips that are on the blade.

Ok, gridsdpeed has two usb port and it understood a computer is needed!

I know an USB connection via computer and on product is used but where other USB connection can be used? If is one gridspeed can be used on two computers then I understand otherwise, I stuck!

According what I read:
power on device can be provided from a PC or from Rasberry Pi correct?

Which version of cgminer supports this hardware?

The gridseed blades use 2 USB ports, and need some sort of computer to run a special version of cgminer to interface with them. There are images around to run them on a Rasberry Pi, but I've got so many spare machines I just run mine on one of those - and yes, you can do other stuff at the same time. They do NOT use GPU at all and put a very tiny load on the CPU that's running their cgminer, and by report you can run at least 20 USB ports worth of miners on that cgminer.

 There are a few other Scrypt ASIC machine models around, but they all cost quite a bit more WHEN you can find them, so a much higher risk vs. attaining ROI - on the plus side, many of the other Scrypt ASIC miners are totally stand-alone machines that talk to an Ethernet port (like Antminer S-series and C1 or anything Spondoolies etc. for Bitcoin).

 I've yet to see any "PCI Express 3.0" spec card fail to run on a PCI Express 2 slot. I don't think I have anything around with PCI-E 1.0 any more to try that but it SHOULD work.



 If you run p2pool, or run on a multi-coin pool, you CAN in fact mine multiple coins with cgminer. The pool I work with for Scrypt does litecoin AND doge.

Thanks for providing some information towards those video cards.
No sure what you're talking about pci express 1.0 but using PCI express 1 to x16 extenders isn't an option!
Even if I had those extender, will still run at 1.0 and not x16 and tends to damage motherboard.

Funny, I have radeon R7 PCI Express 3.0 and it runs on PCI Express 2.0 without problems.
Therefore, having board with following:
2 x PCIe 3.0/2.0 x16 (x16 or dual x8)
1 x PCIe 2.0 x16 (x2 mode)

wouldn't be a problem!

You mention about:
Gridseed "80" blades, it seem great.
Does this depend on CPU and GPU?
Assuming I go with that, can I  use PC for something else as well at same time?

I mined Scrypt with Radions - back when I could at least break even with them. Paid for almost all of the 7xxx series cards I own that way, and most of the cost of the last couple.

 No point in even TRYING that now, unless you like to just hand all of your income AND 3-6X MORE to the power company. You will NOT make money even trying to mine anything Scrypt with a video card. You will NOT break even. You will LOSE money hand over fist, even if your electric is 3 cents / KWH.

 It's not about the cost of the equipment when the electric to run it costs a TON more than the amount of coin you can mine with the equipment and current ASIC stuff for Scrypt has gotten to the point it's cheaper than many video cards anyway while performing a TON better.
 Gridseed "80" blades are wildely available for under $150, for example, and mine around 5 MH/sec (at "stock" clock) for under 100 watts - NO video card is even in shouting range of that performance especially at that price point - yet those units even at current Litecoin pricing are barely break-even. Any video card out there that could even come CLOSE to that 5 MH/sec is going to (1) cost you $500+ (2) Eat 600watts or MORE when mining Scrypt (3) NOT match that 5MH/sec.

https://bitcoinwisdom.com/litecoin/calculator tells the tale pretty well - though it's not taking the litecoin block reward halving into account yet (that halving is due in about 2 weeks) - at which point your electric cost stays the same for HALF the income.

 The current generation Radion series isn't noticeably more power efficient than the 7970 was vs. amount mined - some are LESS efficient, a couple at the "sweet spot" are perhaps 20% more efficient at most.



 I personally like the Sapphire cards, though the Gigabytes got a lot of use and recommendations.

 PCI-E cards are all backwards compatable with PCI Express 1.0 if they meet the full spec on later PCI-E versions, within the physical limit of the slot they have to fit into.

Can you lead me to board having following:?

Intel® Socket 1150 for 4th Generation Core™ i7
Intel® 22 nm CPU
4 pci express x16

Of course, I plan mining on GPU, which of following R9 is best:
1) XFX, GIGABYTE, MSI, and SAPPHIRE

if i was you i will go for:

Intel® Socket 1150 for 4th Generation Core™ i7
Intel® 22 nm CPU
4 pci express x16

since for me is better than the other one, but you should take care about what cpu you will use and if you really care a lot about the efiicient energy or not.
