Thanks so much for your help! Litecoin are several main mining programs - a, ufasoft miner rate, diablo miner, phoenix, guiminer, cgminer.
Exchange is set tdkc by default to use a few threads on all shader blocks the graphics card has at a maximum. So, does anyone knows what bios should I use to improve hash rate? So we will discuss it. Need some advice EDIT:. September 28, , I know most people say not, but what the hell. I was going to try this but I thought the bios should be a. The graphics adapter GPU is able to carry out many similar tasks very fast and effectively, but at the same time it switches to another task slowly.
In some online stores it may reach 50, The main such currency is QuarkCoin. I am having some problems with my 4 gigabyte OC s. December 17, Has anyone here gotten higher thanor is this the limit for a?
Has anyone else heard of this happening? We will discuss graphics cards which are available on the market, as it will give an opportunity to make a mining farm of a necessary capacity.
The selection of optimal parameters of memory clock speed and core clock speed must be done individually for each graphics card. These parameters affect both the mining rate and the whole system stability. Also, overclocking affects temperature and energy consumption of the graphics cards.
The more is the GPU overclocking, the more are the farm demands for the cooling system. If the system has different card series, or cards of one series but by different manufacturers, conflicts are possible during launch and overclocking, which will affect the maximum speed and the whole farm stability. Hardware combinations for a farm also affect the hash rate. A correct choice of farm components like motherboard and RAM also increases the stability and the mining speed of a farm.
For example, as said before: When building farms, one should do some calculations to know the most profitable variant. You need to know energy consumption of the whole farm and calculate 24 hours charges for energy.
Considering these calculations, you can draw a conclusion on the payback period. To make this task easier, there are many mining calculators: There are companies that provide their equipment capacity for a certain amount of money per month.
This way is relevant for crypto currencies, which have only CPU mining. It is profitable in two cases: Operating systems and mining software. OS installed on the mining farm may affect the crypto coins mining speed. Linux The most popular OS among miners. Monitoring tools are brought to the main screen. A detailed description of installation and setup is available here club.
The right driver version choice is very important. Sometimes particular driver versions lower the total computational capacity of the scrypt mining equipment. At the same time the others, on the contrary, allow to achieve high hash rate. There are several main mining programs - bfgminer, ufasoft miner , diablo miner, phoenix, guiminer, cgminer. The most flexible in configuring, stable and informative miner is CGminer. CGminer is managed via the command line.
To ensure that you do not need to reconfigure all the settings every launch or when you change the crypto currency, it is easier to create a.
The basic setup for the miner to work looks like this: Intensity is the key figure affecting the miner's work speed, its value is set from 0 to One must consider that a too high intensity can negatively affect the mining speed, because it MAY exhaust all available memory and actually reduce the mining speed in the best case. In the worst case — there will appear a lot of miscalculations and HW errors.
Take into account that if the intensity is not set, CGMiner will adjust it itself, dynamically, to provide an opportunity of convenient work with the PC. Thread-concurrency controls an optimal volume of calculations which a scrypt algorithm can do. It is set up by default to use a few threads on all shader blocks the graphics card has at a maximum. The value must be a multiple of the number of shader blocks of the graphics card. It is recommended to spend some time to find the best value for your graphics card in order to get the best performance.
A drawback of the reference R9 x and R9 was card cooling without any additional cooling while mining. Thus, the increasing costs and payback periods appeared. But today there are quite a lot of non-reference solutions from almost all manufacturers, which made R9 x and R9 very interesting for building powerful, compact and cold enough farms. I'm getting 3 of the gigabyte OC cards soon.
Sidorovich on May 10, , I'm gonna tweak it tomorrow, i'll post the results. Hero Member Offline Activity: One of the keys to your tuning is that you are using 2 GPU threads. Older series cards like only 1 GPU thread. This presents a problem in a mixed environment. For example, I have two 's and one Spetznaaz on May 10, , As you can see i've been playing about with MSI Afterburner settings, still haven't got the sweet spot quite right, it's amazing how sensitive these cards are to such small changes.
Raspberry pi packages for cgminer Ubuntu PPA for mining related software. Spetznaaz on May 12, , Did you change it in the. I've got a lot of different cards and the XFX ones are the worst i've ever used.
My Gigabyte ones will fly over a piece of cake, my Diamond ones will do over without much effort, but the XFX ones i'd be lucky to hit no matter how much tweaking or OC'ing. MysteryX on May 12, , What's the worst that could happen if the bios flash doesn't work right? Will my card be dead? And I am going to have a as my main card, with three s for mining. Is there any way I can accidentally flash my nvidia card with the AMD drivers?
Sidorovich on May 12, , Have you seen this flash done on the xfx cards which didn't use the reference pcb. Full Member Offline Activity: WeTradeCoins on May 12, , Vilepickle on May 13, , Spetznaaz on May 13, , Being doing a bit more reading if your card is one with dual dvi's it is not the reference board it is xfx's own spec and flashing a reference BIOS will brick it.
I get artifacts when I put in your settings and my card crashes after 20 seconds. I get this everytime I'm going to high with my card. Anyone know how I can fix this?
Hey, so I've made some changes with my setup. Here is the guide that I used and a link to the bios that I used to flash the card: ElBurro on April 29, , Here is the solution for the Ghz card. Mine is a Sapphire Vapor. Flashing is a breeze, I'll tell you the steps I took to get it working. It looks like I won't need to do a bios flash. I have been having problems getting more than one card to work at a time though.
Has anyone here gotten higher than , or is this the limit for a? Sidorovich on May 17, , May 18, , Going to run them overnight and see what happens. June 06, , A couple of "gotchas" that I stumbled into along the way: However, although it worked I was dropped into A: This really confused me and I tried B: After much fiddling about I tried C: Again after much fiddling about and head scratching I had to leave the office I'd brought the rig in so some of the guys at work could give me a hand.
I noticed that one card was a lot hotter than the other. Then I realised I'd only plugged one screen in and had not been using the dummy plug. This one was a gotcha since it looked from cgminer's screen like both cards were working, but in reality I think the hashing was being erroneously allocated evenly ish to both when in reality one card was idle due to not detecting a screen.
Anyway, I hope my n00bish mistakes help someone else. Changing -g to 3 not quite sure what -g does even after reading the docs but whatever! When I try and tweak most things other than clock speeds I tend to get "invalid nonce" errors. This applies to many of the proposed settings on the github LTC mining comparison page - any intensity above 13 seems to barf in particular. I saw something about it being better to use older graphics drivers somewhere but can't find it now.
I've now got three 's in the rig and after reading the consolidated Litecoin mining guide have found a thread concurrency above which seems to work and allow greater intensities without those invalid nonce errors. I'm currently trialling this: A quick way to tell if it is unstable I've found is to try to ctrl-C kill it soon after starting.
If it hangs, its unstable.
