Don't bump your own damn threads.
Get rid of Crimson drivers and install older drivers. Look for the v16 driver for RX5xx hack on these forums, v16 drivers tend to work well.
I installed newest Crimson package and RX570 use newest, but for RX480's i installed 16.9.1 divers because of modded RX480 bios. All cards on one rig tho. 16.9.1 doesn't recognise 570's. And even when 480's with 16.9.1 that PCIE slot gives only 4,5MH/s. I have a rig with mixed RX 4XX/5XX cards. The RX 5XX cards are only supported by drivers 17.4.X and up. Uninstall the drivers in safe mode using DDU and then install the latest driver from the AMD website. After you install the driver and any time you update the drivers, you need to patch the signature check if you have cards with a modded Bios. https://www.youtube.com/watch?v=IAiScXPisAY |

Graphics chip makers Nvidia Corp. (NVDA) and Advanced Micro Devices Inc. (AMD) are both working on graphics processing units (GPU) specifically for processing cryptocurrency transactions, and RBC Capital bet on Nvidia to make the superior chip in their note Friday.
Just goes to show that RBC Capital is clueless. The announced NVidia options for mining-only cards are NOT as good as the announced AMD mining-only cards overall - if they'd put a GTX 1070 or a GDDR 5 (not 5x) 1080 in as an option it would be another story though. They're also wrong about the "much faster" part of that blurb. The REAL advantage for mining-specific cards will be better efficiency. Do you see any confirmation that the mining only 1060 is more efficient than the ordinary 1060? Cryptomined did a video showing the mining 1060's were about the same as a regular 1060. https://www.youtube.com/watch?v=9deSVpjm1Kk |

So it looks like we are at dag number 132.
Is there already a drop for AMD cards at dag 132? I have been getting less than a 0.1 MH/s drop for each card with each new epoch while dual mining. |

The good ones also use a voltage regulator to prevent spikes.
Riser with PCI-E = Voltage regulator needed because PSU gives only 12V over 6-8pin pcie. Riser without voltage regulator = molex or sata = PSU can regulate directly. Only advantage when you need a lot of power over pcie (i.e. RX; 1050/Ti without powerconnector) You are confusing a transformer with a voltage regulator. A voltage regulator is designed to maintain a constant voltage and prevent spikes. It does not step down current, that's what a transformer does. https://en.wikipedia.org/wiki/Voltage_regulator |

this can be good if they removed the 30% less hashrate they are makign ont he 5xx series, it could make sense to buy this instead, if the promised performance meet the spec, but i'm not sur,e until i see proper testing i'm not buying, and also it's hard to get this gpu anyway
I have RX 4XX and 5XX cards and the hash is basically the same for both cards after Bios mods. Which is to be expected, since they are essentially the same hardware with better cooling and power management on the 5XX cards. |

hi all
I have just received gtx 1080 ti in adition to my rx 480 8gb
I have connected gtx to monitor and the other one with second pci-e slot and I have installed only the nvidia drivers and removed amd drivers
the problem comes when I want to overclock both cards, I have used always msi afterburner for rx 480 but it seems that now I can only do oc to gtx 1080
anyone knows how can I solve that?
thanks in advance
You have to connect a monitor or dummy plug to the AMD card to be able to use Afterburner and for the drivers to read and set the temerature and fan speed. dummy plug? like those dvi to vga adapters for example? You could build your own, but it's easier to use an HDMI connector with an EDID chip built in. http://www.geeks3d.com/20091230/vga-hack-how-to-make-a-vga-dummy-plughttps://www.amazon.com/CompuLab-4K-Display-Emulator-fit-Headless/dp/B00JKFTYA8 |

Powered risers control the amount of power drawn through the PCI-E slot and stabalize the flow of current using capacitors. The good ones also use a voltage regulator to prevent spikes. Ribbon cable wires are also too thin to be used under constant load, IMO.

@Claymore check this new video from BitsBeTrippin https://youtu.be/ZzAbECBnJmY?t=4836AMD confirm about DAG issue with Email . @Guys if anyone can make a test using SGminer with OpenCL 2.0 on Linux it will be very helpful Thanks AFAIK, you can't benchmark future epoch's in SGminer like you can with the Claymore miner. we can run it and compare current hashrates, no need to benchmark at all At the current epcoh, the difference in hash rate is not significant enough to be able to make a conclusion. There are always hash rates diffrences when using different miners. One way to get some indication if SGminer will be affected would be to mine ETH and then ETC, which is at higher epcoh. My rig, at it best times, could mine 168 mh/s with claymore miner, now it is 165 mh/s. SO if this SGminer can give me 168 mh/s back, it is all obvious, I don't need to do a benchmark Among other things, the hash rate you get is also dependent on the miner optimizations, settings and configuration options you use in the miner. Claymore's miner and SGminer are completely different miners and use different configuration options. A few MH/s difference for a rig between two different miners is normal and doesn't show anything except which miner is faster, it doesn't tell you WHY. e.g. Claymore's Zcash miner gives me ~320 H/s on a RX 480, with the Silent Army miner I don't get even half that. The only way to conclusively test whether SGminer is affected by the epoch hash drop is to test a future epoch or see if your hash drops with the next epoch using the SAME miner and settings. |

And instantly out again. There's no use with the one per person thing considering you can hold multiple addresses and easily buy a couple of these things (let your friend receive it, etc.) Yea, that's probably why they are only listing the cards for a short period at a time. It makes it harder to be able to place multiple orders. |

Yeah I did patch the drivers, and tried both modded and unmodded bios, but these cards dont seem to play together nicely. Either my power supply is faulty - which it cant be, it's brand new and afterburner shows a constant stream of power working beautifully for the cards, or the used 480's are screwed, which is highly odd, they work fine by themselves. So maybe it IS the power supply, or the motherboard - or the risers! I tried another board, same issue, but I had the 580's on risers before i got the 480's, and they worked great - which is the reason I bought 3x used 480's to add in!
How many cards are you using per PCI-E connector? You could be overloading the PCI-E rails. Some PSU's can only handle 15-20 A on each PCI-E rail. |

I use 1150 MHz core clock and 2050 MHz memory clock with a -96 mV undeclock and get ~29 MH/s with Uber Mix v3.1 Bios modded Samsung cards.

Actually the R9 295 X2 can do ~65 - 70 MH/s but use ~500 W each. If you can pick up used cards and have good electric rates, they are a good option to get a lot of MH from a few cards. Problem is they are going for 3x what they were going for used two months ago. https://youtu.be/TM8Pj_uLqxA?t=5304 |

Things must be rough where you live if you consider $540 for a 1080 and $460 for a 1070 a great deal. You could buy two of the RX 470 4GB mining cards for $500 or the gaming RX 570 4GB cards for less than that, if you can find them and get roughly 20-30% more hashrate for the same price.
Nobody is selling the RX 470 mining cards for $250 - the NewEgg postings were mistakes, they don't even have the cards yet - and the rep I talked to was pretty sure they were NOT going to actually sell the things at MSRP or even close when they DO get them. If you can get GTX 1070 at $400, GRAB THEM - that's bloody cheap at current pricing, and is the same ballpark they were in a month ago before the started getting impacted by the "mining caused GPU shortage". Last time I checked NewEgg (yesterday), for example, the LOWEST they had a "in stock" GTX 1070 listed at was well over $500, and most were $600-$800 of the VERY FEW IN STOCK options they had at all. BTW - they didn't have ANYTHING in an RX 470/480/570/580 for under $500 at all, and only 1 or 2 options under $600 - at current pricing the RX line has ZERO advantage in reaching ROI over the GTX 1070. Trying to call those cards "$250 cards" is not valid and hasn't been for a month or two now. The rep you spoke with is incorrect. The mining cards were in stock at Newegg and limited to one per person for $260 for the Samsung cards and $250 for the non-Samsung version. They are still listed on the website and you can sign up to be notified when they come back in stock. https://www.newegg.com/Product/Product.aspx?Item=N82E16814202291https://www.newegg.com/Product/Product.aspx?Item=N82E16814202283This morning Newegg also had Nvidia 1070's for $399.99 and others at $429.99, limited to one per person. Several places have had the regular RX 570 4GB cards at less than $250 over the past week. You need to act fast because they sell out quick. http://www.nowinstock.net/computers/videocards/amd/rx570/these are 4gb cards. you can find 4gb anywhere. for mining, ideally would be 8gb at least. today i bought 16 evga 1080, i'll post later how they perform. I noticed amazon sells 1080 cheaper than 1070. Suppose you find 1070 and 1080 at the same price, which one would you buy ? That is not true. The Dag file won't be even close to 4GB until 2019 and the diffrence in hashrate between the the 4GB and 8GB is less than 1 MH/s. In fact two of the Powercolor Red Dragon RX 570 4GB cards that I bought for $190 each less than 3 weeks ago will do over 29 MH/s and I have 8GB cards that only do 28 MH/s. Just because you think it's a good deal to buy overpriced cards for the performance they have in mining compared to ther cards doesen't mean they are a good deal. The fact that you would buy 16 1080's without even knowing how they perform in mining only shows you don't have a clue.  |
