Is mining for a day at Full speed the same as mining for 2 days at half speed?

I just found out that if I lower my GPu speed by 20%, I can save like 35% of electricity.

While this could be possible if you're pushing you PSU or cooling to the limits it should not happen that way. clock speeds more or less control wattage usage in a linear fashion - double clock speeds and double your wattage. Voltage needs to be squared when control wattage usage. So 50% voltage is 0.5x0.5 = 0.25 or 25% of the wattage.

So if you take a card that normally runs 1.0v and clock it down to 0.8v but keep the same clocks, you should be lowering the power for the core by 0.8x0.8=64% of previous core usage. Of course other card components will still use the same power like the memory and the fan (assuming same RPM).

As noted above the difficulty change would be the biggest factor.

I can only assume the reason to mine at 1/2 speed would be because of varying electric rates based on time.

Something like that, yeah Wink

Hehe you trying to be sneaky and stealth mine on somebody else's property? Be warned that is considered theft in most countries unless you have consent.

If you're not stealing, an easier option would be to undervolt the card (if possible) and it should put out a lot less heat since power is determined by the sqaure of the voltage as opposed to linearly with the clock speed. A drop of 0.1v or 0.2v on the core will put out a lot less heat and then u don't need to spin the fan hard, you just mine about 80-85% of max speed.

Hehe, no I am not trying to be sneaky.
Where I live we have options for electricity tariffs so from around 10 in the evening till 7 in the morning is dirt cheap.
From 7 in the morning till 10 in the evening though is expensive.
So I was kind of looking into that option but not sure yet.

Yeah you can go ahead and turn on/off the machine during the best mining times. If you stick to a large pool like WemineLTC and mine Litecoin you should have minimal variability - the only difference would be trying to mine during lower difficulty swings. Bust out the calculator after every difficulty change to make sure mining is cheaper than outright buying coins.

I wasn't planning on turning them off Wink

A lot of people are saying is better to just buy coins.
I can understand that given the constant difficulty changes.

To be honest though I kind of enjoy mining

It is nice to watch your coins grow little by little

Its same and its different
There will be different situations and answers of this question.
First of all it depends where you are using your miner? of course its same if difficulty stays same untill 2 days if not you will regret on your next half speed if dificulty rises every hrs or withinn that time.
Depends on electricty and system, if you are running only device for mining then no prob but if you are running device in a rig and with all other stuffs then electrict cost of other stuffs will be added in half speed but if you mine with full speed your electricty cost for other stuff will be same but income will rise so you will pay less.
It depends.

So, if mining for a day @500GH the same as mining for 2 days @250GH? (in terms of profit).

No.

Because, a day have a variable block created ... even if this is planned for 10min.

In reality, it's vary a lot.

So which do you think is more beneficial?

If you drive a car at 40 mph for 2 hours and another car at 80 mph for one hour, which one goes farther?

40 mph for 2 hours cause you would meet some driver which go at the speed of 30 mph which force you to slow down..

The problem is driving at night, or when it is raining, or there are other cars that cause traffic.

With BTC, difficulty is continually increasing by a large amount every couple of weeks, so you'd be much better off doing all the mining sooner rather than later.

Alts however - particularly the lesser known ones - go up and down in difficulty a lot so the opposite could be the case.

It's the same in the long run if you compared for example 500 days at full vs 1000 half-days, regardless of pool payment method. There is on caveat: You have to do this at the same difficulty.

So for every day at diff X, you need 2 half-days at diff X. If your two half-days happen to have a difficulty adjustment between them, you will make less.

now it gets more complicated. It depends on how a pool credit its shares and is shielded on pool hoping and how lucky will they be at this particular 24hr window.
I'd suggest to not keep all eggs in one basket Wink

In a way yes but why are you asking this question?

In a way yes?

I thought directing full power at one pool for a day would get me more shares then half the power for 2 days.... Huh

?
At least that is my opinion.

I am asking because I want to know in case I wish to mine different coins per day.
