What I find interesting is that there are so many variables at work here that determine profits (power costs, difficulty, current BitCoin value). Obviously there must still be some, even after power costs, for those who already have the equipment, or continue buying it cuz they've wanted state-of-the-art equipment on their system since WAY before the BitCoin existed (e.g. gamers). I happen to be one of those people who wants a great video card in my system so I have a good system, mining BitCoins is just a current, temporary bonus. But one thing I've noticed: a lot of posts made in May stated how mining was profitable then, but won't be as difficulty increases. But back then, a BitCoin was only worth 4 and a half bucks! Obviously the price is volatile, unpredictable, and has some inherent risk, but what investment in life isn't?
People on the internet like to bitch and moan about all kinds of things. I'm sure that back in May life was different and thus required different amounts of bitching than the current state of available things of which to bitch about now. Life's a bitch, just mine coins and enjoy it. If it ends up being profitable, great! If not, you tried.
My word of advice, with my $5K invested in BTC mining, is that there are too many variables to do very accurate projections. You either go for it or don't. BTC is a gamble. It's better than going to a casino though
well.. $4.50 at 200k difficulty (average in may) and $14 at 1.6m difficulty. that's 155% more profitable than it is today (before electricity cost, so effective profit was even higher).
edit:
At stock clocks, the difference will be around 140w. If unlock the shaders and overclock, probably 200w or more.
If its only for mining, don't overclock your cpu, or replace your I7 with an I3. You can also lower the memory clocks of your video card, it will lower the temps and power consumption a little bit. 250MHz seems the lowest I can set for DDR2 and DDR3 cards without affecting hashing performance, and 300-400 for GDDR5. Lowering mem clock can also help to stabilize your card at higher core clocks.
I need help underclocking my i7 in bios on mobo Asus P6T SE to reduce CPU power use while giving GPU more of the available power needed for mining.Also how to underclock 6GB RAM or wotever it is to reduce power use of these parts to make more power available for GPU mining.
If some1 knows how,then please either put it in this thrad if possible or if not link to it in ur reply.
Thanx n4l3hp 4 the advice on hte GPU power use.
P.S does someone know of a good cost effective SSD at 80GB and 120GB capacities thanx?.It needs to be long lasting,reliable,cost effective,fast and low power consumption.
alright, first of all, you don't use an i7 as a dedicated miner. it's way too expensive. secondly, your post sounds as if your PSU doesn't have enough power to support your graphics cards if the other components use up too much power. that's not the best case here, you don't want to run a PSU at its maximum capacity. lastly a ssd doesn't consume much power, you can go with any type/brand. even a hdd doesn't consume very much when idle.
solution:
get a dedicated rig, low power (+consumption) cpu, a usb stick with linuxcoin, a few cards, and a decently sized PSU (of course you need a board and ram, too. but there's not much you can do about its power consumption).
ps: your nick and your language.. wow
