Title: best mother board for mining Post by: splat44 on August 07, 2015, 10:42:39 PM Which asus board is best for ecurrency mining?
Here spec FM2+ socketed AMD chip (up to 4 cores) 4 pci express x16 or Intel® Socket 1150 for 4th Generation Core™ i7 Intel® 22 nm CPU 4 pci express x16 I know some asus board has the following: intel core i7 4 pci express x1 Using those extenders, would it not burn board? I read when using extenders from x1 to x16, will still run as x1 and not x16 Lots asus board support radeon gpu crossfire, is it recommend or suggested using crossfire support for mining?

Here spec FM2+ socketed AMD chip (up to 4 cores) 4 pci express x16 or Intel® Socket 1150 for 4th Generation Core™ i7 Intel® 22 nm CPU 4 pci express x16 I'd go with Intel since Haswell CPUs are more energy efficient. But above all, I'd go with the cheapest: every $ you put in your hardware will push your ROI further back. I know some asus board has the following: intel core i7 4 pci express x1 Using those extenders, would it not burn board? It's always a risk.

Yes, hybrid extenders run at 1x. And no performance gain using SLI/Crossfire. Title: Re: best mother board for mining Post by: splat44 on August 08, 2015, 02:14:30 AM Alright, I came through following:
https://www.asus.com/ca-en/Motherboards/Z87A/specifications/ (https://www.asus.com/ca-en/Motherboards/Z87A/specifications/) Has followings: Intel® Socket 1150 for 4th Generation Core™ i7/Core™ i5/Core™ i3/Pentium®/Celeron® Processors Supports Intel® 22 nm CPU 2 x PCIe 3.0/2.0 x16 (x16 or dual x8) 1 x PCIe 2.0 x16 (x2 mode) So mining with 3 gpu(s) should do right and using ic7 (4 cores) won't be performance problem?

However, several kind of radeon r9 such as: 1) XFX, GIGABYTE, MSI, and SAPPHIRE Which kind of those are best for mining?

What coin are you planning to mine? If it's a SHA256 coin like Bitcoin or Namecoin, forget it - nothing SHA256 has been mineable for anything remotely resembling break-even with GPUs for years. If it's something else, this question should be in an appropriate Altcoin part of the forum. Title: Re: best mother board for mining Post by: splat44 on August 09, 2015, 12:34:22 AM I am dealing with multiple coins using:
multipool.us I totally agree on SHA256! You're missing the most important part, which definitely affects choice of GPU. What coin are you planning to mine?

Title: Re: best mother board for mining Post by: QuintLeo on August 09, 2015, 09:17:28 AM That doesn't answer my question, haveing never looked at whoever multipool.us is or what coins/algorythms they pool for.
Title: Re: best mother board for mining Post by: splat44 on August 09, 2015, 04:03:50 PM Alright, Multipool.us is a pool which allows miners mining multiple coins (three coins) at a time:
ANC, AUR, CAP, DGB, DOGE, LTC, VIA Here what I'm ming for example but it changes day by day: DOGE, LTC AND VIA Does this answer part of your question? In fact, mining only depend on hardware that is use and not type of coin I suggest we stay with hardware topic/question seen on posts: #3, and #7 Motherboard question is answered but rest on GPU is still unclear! That doesn't answer my question, haveing never looked at whoever multipool.us is or what coins/algorythms they pool for. Title: Re: best mother board for mining Post by: QuintLeo on August 09, 2015, 04:25:34 PM DOGE and Litecoin are scrypt - NOT GPU mineable for even close to breakeven. I don't recognise the others but presume they're also Scrypt.
You need Scrypt-based ASIC units to mine with, not a montherboard and/or GPUs, unless your electric is FREE or you like giving your power company money for very little return. Title: Re: best mother board for mining Post by: splat44 on August 09, 2015, 06:21:25 PM ASIC units, for price we pay these day are hardly breakeven! Less is cost better it is!
We also pay electricity using those those things! My power cost isn't an issue! Most lots radeon gpu use scrypt and produce a fair bit! Although, I not speaking miner software, the ones supporting GPU are 1) sgminer5-1 2) cgminer3-7.2 Sgminer5-1 is by preferred one as we can mine 3 kinds of coins at a time and cgminer doesn't! In fact I am mining on radeon r7 I believe and still produce more than CPU using preferred miner. Getting radeon R9 would be better!

Title: Re: best mother board for mining Post by: QuintLeo on August 10, 2015, 08:17:32 AM 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. Title: Re: best mother board for mining Post by: splat44 on August 10, 2015, 07:54:13 PM 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.

Title: Re: best mother board for mining Post by: QuintLeo on August 10, 2015, 11:02:20 PM 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. Title: Re: best mother board for mining Post by: splat44 on August 11, 2015, 02:15:43 AM 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?

Title: Re: best mother board for mining Post by: QuintLeo on August 11, 2015, 02:25:15 PM 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. Title: Re: best mother board for mining Post by: tech_solutions on August 11, 2015, 03:45:04 PM can anyone help me out which computer hardware is good for minning :)
Title: Re: best mother board for mining Post by: splat44 on August 11, 2015, 07:34:07 PM Ok, let's see
1) Windows PC 2) Raspberry Pi So gridseed can run on either system right? The Gridseed 80 actually is 2 "blades" in one device, one USB port per "blade" is needed.

Title: Re: best mother board for mining Post by: QuintLeo on August 11, 2015, 10:50:30 PM 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.

I do agree that the Maxwell NVidia cards are the way to go for cryptomining on GPU-viable coins now. Title: Re: best mother board for mining Post by: splat44 on August 13, 2015, 05:45:17 AM 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! 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. Title: Re: best mother board for mining Post by: QuintLeo on August 13, 2015, 02:04:58 PM 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. Title: Re: best mother board for mining Post by: splat44 on August 28, 2015, 09:52:09 PM 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.

Title: Re: best mother board for mining Post by: QuintLeo on August 29, 2015, 12:26:25 AM 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. Title: Re: best mother board for mining Post by: splat44 on August 29, 2015, 08:09:09 AM I checked latest version of cgminer 4.9.2

I know how to use putty based on enough information Using cgminer: Code: ./cgminer --scrypt -o server <address>:<port> -u <username> -p <password> --gridseed-options=baud=115200 freq=850 chips=80 --hotplug 30 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? 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. |
