I have a fairly good graphics card, but for some reason the hash rate I've gotten in the miner I use (50Miner) seems extremely low considering that the last generation of this card (GTX560) has something like a 100 MH/s hash rate. What I've been getting is around 20 MH/s. Am I doing something wrong? I think one cent gained over three hours is a bit below average. =.=

In case you missed it, I'm using a 2GB Nvidia GTX660 card.

You could try a cuda miner and a few flags, but in all honesty all Nvidia cards are low. I have a 580 and its only pulling 145.

Side note, there is a reason the versions of cards lower that the X7X model are not usually listed in hardware comparison. For most of them the power/heat to hashrate is not worth the attempt.

See, that's the problem. From what I understand, your GTX580 is about on par with my GTX660. Annnd you're getting a hashrate 8 times faster than mine. I must be doing something wrong.

What would i get on a sweet 9800 GT that I found in my junk drawer?

Around 8 Mhash lol

I'm having trouble figuring out how to get it going under Fedora 18.  I can compile cgminer to get cpu stuff going, but I can't really find a good guide to get Nvidia stuff going.

I finally got it going.  I'm getting a whopping 4.32Mhps now.  And.... my desktop is moving horribly slooooowwwww!  :)

Edit: 6.090M/6.041Mh/s

Hey Ferret, Switch over to GUIminer using Open CL with no flags used and advise what rate you are getting on the 660.

Getting 19.24M/19.10Mh/s on my NVIDIA GT620 with cgminer.

130 MH/s on a Gtx 680.
AMD cards are a lot more suited for mining.  ;D

What about a gigabyte GTX 660 Ti OC? :)

598m/hash on my AMD 7950 for £240

My gaming rig. Just bought another for mining :)  Long term project and also have it for gaming :)

Cool, nice M/hash !

Personally I get around 550 Mhash from my 7950 from Gigabyte overclocked at 1120 Mhz.

Got it for 289$CA when it was on sale like 2 month ago so it has probably paid for itself now if you account the energy used have been reused to heat my loft ;0)

AND GAMING WITH 7950 IS AWESOME

there must be something wrong with my card, or something else. i have a gtx 660 sli setup and im only getting around 10-12 KH/s at best using cudaminer. could you post you config? also how much could you get your 590 up to?(might make Another miner with a 590 i have laying around)

Kind Regards Pesoen

for one thing i think nvidia cards are not good for mining, and second i think mining in sli or crossfire mode is not good either . just my thoughts .

Not to raise the dead here, but I just got into the mining game and I'm practicing on Ducknote. I have a Core i7 860, 2gb GTX 660, eight gb DDR 3 and I'm using tsiv's CCMiner fork. I'm not even getting khash/s. Can someone take pity on a novice and help?

I don't know much on the issue, but just found the post https://bitcointalk.org/index.php?topic=167229.msg7539544#msg7539544.
The person get 120 hashes per sec with his GTX 660.

What hashrate do you get exactly?

It jumps between 190 h/s and about 60-70 h/s. While I was (briefly) minding Ducknote earlier, it averaged out to 80 h/s. I don't know if it's my equipment setup or the specific kind of algorithm I was mining, but according to other sources I've been perusing for the last week (none of which I have to hand, unfortunately), I should be getting in the 120-125 kh/s range with this GPU.

I know NVidia isn't ideal for GPU mining, but for the moment it's all I've got.

hi guys,



im reading up on all these forums and watching videos on how to set up mining rigs. a lot of people have been talking about setting up systems with multiple high end radeon cards such as the 290x etc...

but when they talk about the hash rate being achieved, its like 300-400 kilo hash /s (for each card). 

yet i did a test run on my laptop where my nvidia gtx660m card is achieving 40 mega hash/s on average.

why is my laptp achieving mh/s when these dedicated rigs are only achieving kh/s?


am i missing something? because im really confused here

Maybe try to check Mining section of this forum.

It could clear your doubts and questions very probably.

Cheers.

They are most likely talking about litecoin (scrypt algo) hashing rate. https://litecoin.info/Mining_hardware_comparison




And you are testing with bitcoin (sha256 algo) hashing rate. https://en.bitcoin.it/wiki/Non-specialized_hardware_comparison

you need to undervolt your GPU and tweak a little bit...
you need to download, edit&modify, upload bios to drive down power consumption and rise performance!!!

Even with undervolt, overclocking, your hashrate will still be low. Cuda cores aren't optimized for openCL operations compared to steam cores which AMD uses. However, with the recent released GTX 980 and 970, their hashrates and electrical usage are slightly improved but for SHA256, the profitability is still negative due to the amount of ASICs on the market right now. For altcoins, there MIGHT be bits of profit but the profit would still be small

i quote it!!!

but it depend prom miner code too...
i know who there are cudaminer  software for nVidia 750 Ti with really good performance and with kHash/Watt greater than miner for AMD.

I was too late to try GPU mining, but I always heard that nvidia sucks badly. Which software and coin are you talking about here?

He's talking about this (https://bitcointalk.org/index.php?topic=167229.0). Nvidia sucks on their previous chip architecture for mining but after the introduction of Maxwell architecture, the performance have improved greatly on the power used per mh.

sure..
i think now the best choise it is cudaMiner with nVidia 750Ti..
this GPU are cheap and low power consumption...
you could read something about the new nVidia 970 and 980.
They are the 750 big btother with MaxWell core.
But i do not know so much about mining power...

Well, your choice is incorrect.
AMD's R9 290 is lower in price and better in performance, based on the power usage and performance of each card. Both of the cards cannot beat R9 290 in the performace and price.

sure... radeon 290 it is better in performance...

but if you consider hash rate power, cost and power consumption??
who is the winner???
i think 750 ti it is a good choise...
and when you want to resell it is much more newest and you will be able to sell better!!!

Let's do the math for a minute: How high would the Bitcoin price have to go that mining with such a GPU still made sense, if we assume a constant price of BTC? If I had to make a guess... I think $30k maybe?

sure!!!
bitcoin price it is for sure another variable to add to get the right date on ROI ...
but price it is not sure...
so.. if one of the variable is not sure... the result is not sure!!

and the ROI go far and much more far!!!!

Assuming the current difficulty of 40300030328, 1 GH/s mines 0.00001248 BTC per day. The most efficient GPU I could find uses about 0.333 kW per GH/s. Assuming a power cost of $0.10 per kWh, 1 GH/s costs $0.80 per day.

In order for the GPU to break even, 1 BTC would have to be worth $64,102.56, so $30k was not a bad guess.

wow $64,102.56 maybe 100 years later will touch that price lol

AMD is way better, if you really want to mine you should sell the card and then get an AMD one and use cgminer. If not, cudaminer is your friend but I dont expect much at this point.

ahahahaha

100Years!!!!

this make me ROTFL!!!

really change your life!!!

... and just in 100 years

 ;D ;D ;D ;D ;D

Maybe is better to mine with an old 3dfx Voodoo2 card :)

nVidia RIVA 128!

hum!!!
i remeber good perfo with OLD MGA Matrox!!!

 ;D ;D ;D ;D ;D ;D
