Is there a way to increase hashrate mining on a PC?
Doing nothing but opening minor and go, I get roughly 300m/s, can I increase this or is it already capped? (GPU)
Cheers!

Have you tried overclocking the GPU? It might damage it, so be careful when doing so.

No not yet, wanted to check if there was any other simple newbie way I might have missed.
Plus, I have 2x GPUs, does it automatically (GUIMiner) use both?
Thanks.

Im not sure. Im not a miner myself. I hope you can find a solution! Good luck!

Depending on your gpu make & model you can look and try different settings that cgminer provides. What are you mining: btc, ltc or something else? On Windows or Linux.

Look for the mining hardware comparison chart to get ideas.

Messing with your gpu settings can break it.

Hi,

Realistically CPU and GPU mining aren't anywhere near worthwhile now.

At 300 Mh/s you may make 20 cents a day which won't come close to paying for the 150w+ needed to run your GPU.  You can get an Asicminer USB block erupter for under $20 which has the same hashrate as a fast GPU but only takes 2.5W of power, but even with this you are unlikely to break even IMHO.

Have a look on ebay for "ASIC Bitcoin" or "Bitcoin miner" to see some options.

I actually dont have to pay for any energy usage so that isnt an issue, but i understand that its a snails pace, and at those numbers more for fun and seeing how much I can output.

Free power is always good!

I'm currently mining at ~96 GH/s using a pair of BitBurner Fury cards (~150W total). Since the last difficulty increase to 511M, I mine about 0.09 bitcoin per day (about $US25 at the current exchange rate).  This works out to about 26 cents per day per gigahash, which means if I was still mining with my Radeon 7950 GPU I would get around 10 cents per day (perhaps 0.0004 BTC).

Anyway, cheers and good luck!

I used to open GUIminer twice and select a a different GPU in the drop down menu for each one.

Right click the Windows desktop and select AMD Catalyst Center then Overclock with AMD's Overdrive feature it shouldn't work without breaking it.

Like people say mining Bitcoins with GPUs is no longer profitable. You'd be better trying Litecoin.

I think it has to do with your -v flag settings.

If you have a ASIC, it might be a little profitable. But if you have a GPU, its no longer profitable unless you mine Alt scrypt coins.

just bought r9 280x, wonder how good it can mine altcoin  ::)

delete your guiminer and setup cgminer

a lot of threads for this one

scrypt is "profitable" as of now, even without "free electricity"

scrypt as in LTC and Feathercoin?

Yes. Or even pools that mine the most profitable coin and payout in BTC, like hashco.ws or multipool.us

However, for speculative purposes, it can be wiser to mine a coin that you see it has future and hold it.

Can I increase mining by changing pool or software?

GPU mining bitcoin is dead, you can choose other cryto like Litecoin, feathercoin etc.... The only way to increase your hash further is overclocking. But it would consume more power and more heat..... Good luck ...

It's honestly a waste of time to mine bitcoins at this point you're better off mining alts and then transferring those into bitcoin.  You'll probably make more bitcoin as a results anyway.

Overclock it but don burn it  ;)

What is the eye rolling for? I have some 280x cards and they mine litecoin beautifully.

just buy some hash power with cloud mining: actually it is just 0.09 BTC  for 1 Gh/s.
this is the link if you wanth to know more:

and how much do you make per day with 1 ghash?

i have 13 Gh/s and i make 0.0128 BTC daily

Probably somewhere near .001BTC/day.

In other words, a complete and total waste of money.

if you know how to trade GH/s you can do much more  ;) . you have to play on the daily up/down of the price to make nice profit.

this is a mix of mining and trading. and i like this way.

gh/s always going to be worth less, especially while making crazy diff jumps.

3 months to ROI if difficulty stays the same, but estimated difficulty rise is 4x just for early next year when all preordered hardware is received - no way to be profitable

For BTC there is currently no big reason for new miners to join the club. If you are thinking long term, that may be work out.

Funny is that ppl jumpsbuying from BTC/LTC/FTC/PPC to make some profits (which work out) but looking at the current rate $->BTC wait some days, BTC->$ buy hardware. You bought hardware with 30% rebate - doh. And you missed xx days of mining BTC (which would be worth 0.0xx BTC)

Cloud Mining .. hmm .. actually that is nearly the same as buying BTC directly. In my Opinion. Actually you are renting hardware. Which in long term is more expensive and you get always less revenue.

In Mining Business currently everything is up to where the ASICS will go. You will just not be able to conquer against the big ASIC Farms. Look it like this. They got a big farm, make a lot of money, they spend money to get an even bigger farm. You will not be able to conquer with them. Never. At some point in time that will be meaningless? No, because there are TransAct Fees then. And the big farms will be already massivly big. (they are the new banks)

This is one reason why i prefer LTC atm .. or any other Crypto which aims for wider hashing distribution. PPC is to new for me, but seems to be the ultimate way to go

If I am calculatin right with the current value of BTC of 300 USD, you are making a daily 3.84$ .. not mentioning the hardware initial costs and power consumption. I wonder if this is profitable? (seriously)

Maybe for longterm it really is .. depending on which value BTC will have in 1 year, you will have made a lot of them - if you do made some after all concerning the risen difficulty.
