Title: Nvidia GTX 650 Ti very low hashing rates why? Post by: papajo on October 10, 2013, 01:12:13 PM Hello I have a GTX 650 ti GPU and I manage to do only 45 Mh/s I have seen on charts online that a GTX 250 which is a much weaker cards puts out 80 Mh/s so why do I have so low hashing?
Also I have an old 9800 GX2 could I use them both for mining? should I set them up as different workers? I also have a Dedicated PhysX card is it compatible with any mining software?? Last but not least I can not run mining under CUDA (with cudaminer for example) could anybody give me a little heads up about this? thnx Title: Re: Nvidia GTX 650 Ti very low hashing rates why? Post by: RaTTuS on October 10, 2013, 01:25:58 PM NVidia are good for floating point calcs
ATi are good for Integer Bitcoin uses integer yoou would be much better off buying a couple of USB mining sticks than trying to get the GPU to earn anything IMO Title: Re: Nvidia GTX 650 Ti very low hashing rates why?

Nvidia is not good for this job, so don't waste electricity. Title: Re: Nvidia GTX 650 Ti very low hashing rates why? Post by: papajo on October 10, 2013, 02:44:42 PM yes I know that ati is better than nvdia... its just that GTX 650 ti is a much newer and stronger card than gtx 250 so isnt it stranger to have lower Mh/s than the the GTX 250?

Post by: vpitcher07 on October 10, 2013, 04:08:04 PM If you mine at that rate i doubt you'll get much more than a few cents a week at this difficulty and it'll only go down from here. If you want to make anything, buy a block erupter but don't expect to make your money back. I have 2 and make a little over a dollar a week with 24/7 mining....and that's at about 660 MH/s.

It's not strange because that cards have different architecture so they work differently on different tasks. GTX 600 is gaming series. Title: Re: Nvidia GTX 650 Ti very low hashing rates why? Post by: hulk on October 11, 2013, 10:42:09 AM Cuda miner to increase the hash rate. But anyway dont use nvidia for mining as you are wasting ur electricity and spoiling your card.

Post by: papajo on October 12, 2013, 03:29:51 PM Well I said that I dont know how to setup cudaminer everytime I tried it either couldnt connect to a pool (like slush) or if connected it didnt had any MH/s rate (I think I manage to connect it to BTC guild)
Also I know that Ati cards are faster.. but my question was different since my 650 TI is a faster model than the 4 year old GTX 250 in any case (Clocks,ram,shaders,pipelines,cores etc) why does it produce less MH/s than the 250... maybe the fault is somewere else....

nVidia is just plain bad for your card and for your utility bill my friend. They are just optimsed in a other way, you can have a trillion shaders and shizzels but it aint gonna work... Title: Re: Nvidia GTX 650 Ti very low hashing rates why? Post by: papajo on October 12, 2013, 08:31:52 PM Well no it doesnt how did you came up with that... see this too: https://en.bitcoin.it/wiki/Mining_hardware_comparison#Nvidia
again i am not telling that I should have big MH rate with my nvidia GTX 650 ti I know the rate will suck I just dont know why it sucks that much maybe I need to do some settings? or update something besides the GPU driver... the chart that I linkded does not have my card but it has its previous revision GTX 550ti which puts out more Mh/s than GTX 250 and a stronger card of the 6xx generation that does even better so I should be in the midle.. Title: Re: Nvidia GTX 650 Ti very low hashing rates why? Post by: Wipeout2097 on October 13, 2013, 01:07:49 AM It's probably because from the serie 5 onwards, Nvidia "focused on gaming", or in other words abandoned some instructions that are important for mining, or crippled the card.
This benchmark also shows a serie 5 card much faster than the 6: http://media.bestofmicro.com/Y/M/386158/original/30-OpenCL-FAH-Implicit-Solvent-FP64.png Title: Re: Nvidia GTX 650 Ti very low hashing rates why?

I advice selling it off and buying Sapphire 7950. Title: Re: Nvidia GTX 650 Ti very low hashing rates why?
