Hash Rate Low on GTX660?

[Simon8x]

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).

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

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

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

[orsotheysaid]

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.

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