ZEC and PASC mining is done, no dreaming again ZEC early adopter like BTC did, just go get full time job guys, and ETH couple next month will switch to POS, ton of millions GPU out there will resell again noobs miner who lot invest because ZEC show, will got learn  dream become rich from thin air - will vanish soon, old gpu will back to the grave again, oh noobs, see you soon at GPU market true miner will be miner forever, noobs will out soon, it will be back like 2015 again ha ha, and you aren't even a noob, and so dumb. I think it is the greedy people who expect instant gratuity and as a result spread negativity the most. People who are supportive of these coins and open source simply do not talk like that. The demanding voices of a select few "Linux" users in this very thread sickens me! Someday there may be a Zcash or Pascal gift card available in the local grocery stores, and that will be the day this will all pay off for those who are patient and supportive! When a coin is only worth .50 USD it is not going to financially destroy to many people to just hold the coins until they are worth cashing in! I also do hope Claymore has a few other irons in the fire! I don't think he is saying the coins are dead. he's pointing out that when ETH goes POS all those miners are out of jobs and will be moving to other coins. There are a lot of ETH miners and with them moving to ZEC, PASC or ETC is going to drive the difficulty way up making them much less profitable and therefore a lot of GPUs will cost more to mine with than they are making. There are some lucky enough to get free power but I highly double those with free power are big mining farms and are more the hobby miners. |

I have switched to Linux ( ubuntu 16.04.1) but have been experiencing my screen not being recognized between switching rigs ( plug in hdmi in one rig and plugging back into same gpu I started with on another rig ) also on startup I have seen my screen not be recognized. Here's what I did: install ubuntu Reboot Sudo apt update Sudo apt dist-upgrade Reboot Sudo install new amd 16.50 Reboot Run miner, see gains  Move to next rig repeat Came back to the first rig and screen isn't recognized. Missing anything? I know i'm not answering exactly what you expect, but how does that matter ? Can't you use ssh to admin your rigs ? Or the issue isn't about administration but rather about the miner not working because the screen is not recognized ? => My setup is 100% headless, no fake hdmi or anything and it works like a charm. Agreed - headless is the way to go. There's an issue with the way xorg works in the new versions of Ubuntu. I have found that installing 3 packages makes it work well. This is what I do: install xorg xserver-xorg-legacy xserver-xorg-video-dummy Edit the config file for xorg-legacy: /etc/X11/Xwrapper.config delete the last line: allowed_users=console insert at end of file: allowed_users=anybody needs_root_rights=yes then set up the xserver-xorg-video-dummy There's a bit more to getting the headless fully working in a screen, but this gives you a start. I don't want to keep flogging my build guide, you can probably find a link in a previous post if you want. It took me a while to figure it out, but once you get full headless going it's wonderful. I tend to get slightly less performance out of the GPU that my monitor is hooked to, although it is a XFX R9 380x vs the rest of the cards in the system are just ASUS R9 380 Strix. If I were to switch it to headless would I gain a little extra performance off of that GPU? I'm not positive the less performance is due to the monitor being hooked to it or if the 380x has less performance but I would think if anything it should be more than the 380. |

what hash rate does the 7950 have? also how much power draw do they have?

Can someone running 7950 cards post what they are getting for hash rates and how much power they are drawing? a friend of mine wants to sell me his 7950 and I want to know if it is worth running at all. -thanks

Just switched over from Claymore's and getting much better performance. But I saw a mention of fan control in the messages here on Bitcointalk. Do I need to be worried about my fan speeds or am I ok to just let the fans run where they are? With Claymore's I never needed to worry about them and it always displayed what they were running at. I'm running R9 380 Tonga cards on Linux 14.04
Optiminer doesn't touch the fans, so they stay at whatever the fan speed is when it starts. You can use aticonfig or atitweak (what I use) to set fan speed. So the GPU itself won't increase the fan speed as it gets hotter? I thought Claymore's fan control was to just override the GPUs control and run the fans faster to cool it more. Claymore does the active fan control, if you set that option, otherwise it doesn't change it. I set all mine to 100% at boot time and forget about it. So what would be a max temp a GPU should run? obviously cooler is better but what should a max be for a card that is continuously mining? Depends on the GPU model. On Nanos, the card will not allow temps above 84C. If it can't adjust the power level down far enough to keep it at or below 84C, the card will shut down. Generally, you'd like to keep GPUs at 80C or under, although some GPUs, e.g. 290x (I think), can run fine up to 90C - that's how it was designed to run. I have ASUS R9 380 Strix and XFX R9 380x cards. They pretty consistantly run 67-69 degrees and the fans are about 35% (very quiet) so that makes me feel better. I haven't been pushing them too hard but now with optiminer kicking claymore's ass in hash rate I'm getting a little hungry and going to try taking a card out and putting in windows to undervolt it slightly and then play with overclocking on the linux side. They are a marginal card for mining but I got a heck of a deal on them and couldn't justify going to 480s at the time. Going from Claymore's 11.1 to Optiminer's 1.5 I gained about 15-17% which is better but still not great. I had heard that some cards had a history of starting on fire. was it a particular card or series? Just curious what card models they were. |

Has anyone found a reliable bios mod for the Sapphire rx 480 8g cards that reduces power but keeps the h/s rate respectable? Most of what I have found on forums have been unstable. I have 4 rigs with 6x Sapphire 8g 480's that each run at around 1200w (and I have a 1300w psu) and 11.5A and deliver 260 H/s on each card with the stock bios and I am having to reduce their intensity each time the mining software speeds the mining up or the whole platform shuts down due to exceeding power limits. I have played with different power tools such as Watttool (Wattman is useless for multiple cards and settings in Claymore just freeze my systems) but I am a bit of an inexperienced computer user so I am not sure what to try and I don't want to damage my systems. I have read every page of this forum as I have worked through all the same issues with Open CL and cards not being recognized, and I appreciate the degree this forum supplies ideas and methods to help others work through their issues. So I am asking my first question around suggested settings in Watt tool or perhaps even a stable and capable bios mod that keeps power down while not giving up on the current performance, if possible. Any help is appreciated.
why not just download MSI afterburner, and bring voltage down to about -75mv to start off, see if its stable. 1200w is too much ! By undervolting you'll get a lot of power savings. Is there a 'chart' somewhere for undervolting? I have a mix of 390/290/290x/380/280 etc. and would love to find a way to undervolt them to save power but don't really want to do it 'card by card'. Or am I better off just using Wattman to drop the power 'safely' to wherever each rig will run without crashing? What speeds are you getting off of your 380 cards? I'm only getting about 160H/s on mine and trying to figure out if that is normal. Seems low. |

I'm running a Linux 14.04 rig with (4) MSI R9-380 4Gb & (1) XFX R9-380x 4Gb cards in it. On Claymore's 10.0 it's getting about 812H/s while drawing 850 watts at the wall.
So I'm only getting about 160H/s per card.
Is anyone else running 380s? If so, what are you getting for a rate on them? Is there any way to bring the voltage down and/or hash rate up on these cards on Linux? If so, what program are you using? At this point they are just slightly profitable
Thanks for the help.
