Bitcoin Forum

Hello.

With todays reward halving on BTC, how do you think and where are you switching your miners now. Any new, good projects?

I recommend either Litecoin or PPC Coin, in that order.

ebay.

LTC is no good for my 7970, was not working stable atleast ~ month ago.

With a lot of tuning and frustration, I got my Gigabyte 7970 GHz (1100/1500MHz stock) to run stable-ish on Reaper v13r4 using AMD drivers 12.10, 12.9, and 12.11 beta 8.
The 12.11 is by far the most unstable though, and I still only make ~380-440KH/s.

However, with BTC GPU farms pointing at LTC because of the halving or because of the ASIC's, development on LTC miners will increase and a more stable version will be released.

However, it's still a crapshoot what you'll get.

For example, my game developer friend gets ~550KH/s on his HIS 7970 (Non-GHz), and the only difference was that I have 8gb of RAM to his 16gb, and he has a 3960X and I have a 2500K, and I was using 12.9 and he was using 12.11 Beta 4.
I upgraded and it became too unstable to run, yet he gets 110KH/s more than me at mostly the same settings.

Weird glitches like this will be fixed in time, especially with the HD8000 series (Code named Southern Islands, wasn't it?) coming out soon and a wave of Tahiti's hitting all-time low prices on retail chains and eBay.
Not to mention the vanilla 7970 is only $400, compared to the 7970 GHz's $450.
A quick BIOS flash and you just saved $50. And hell, the Gigabyte 7970 is as fast as the reference 7970 GHz.

LTC mining is heavy on VRAM and system ram

I tried running rigs mining LTC with 1 or 2 gb and it would crash everytime.. 8gb low performance.. gave up there.

So for LTC it needs atleast 16GB of RAM ?
WHen i tryed LTC minig, it was mining well and then after a wile it reports very low speeds.

How abot Terracoin, any thoughts? I dont like that it has no exchange.

I'm not sure. I'll see if I can bother him for a reboot to see if that affects it.

I'm a big fan of Terracoin.  The exchange problem will eventually work itself out, especially once more gpu miners jump on due to the halving.   

I'd hate to destroy my 7970s with LTC mining. They've been mining bitcoin undervolted and downclocked for 7 months with no issues at all. Time to start gaming again...

That's why I feel the best options (for me) out there right now are PPC and TRC.  LTC is a great coin and all, but it just works my cards so hard.  The heat they produce is much greater than mining the other coins. 

It does not. I mine LTC sometimes with a 6990 in my gaming desktop with 8GB of ram at full speed.  However, I have gotten lower speeds than expected mining LTC with dual 5970s and a single 2GB stick.  The desktop has a much more powerful CPU than the mining rigs as well. I would be interested to know the system ram and CPU requirements of optimal LTC mining, is this documented anywhere?

In response to the OP, currently LTC and PPC mining are more profitable, but everything should even out after a few days as miners shift to the most profitable coins.

a single 6990? with 8gb?


I was trying 5 x 5800 series.... with 8gb and performance was shit. I will be trying this same rig again with a 16gb kit.

I believe in Bitcoin. That's why I mine. I believe in their success, and longevity. Bitcoin adoption will have many hurdles, but I believe it will prevail.

I do not believe in alt-coins. I actually believe they hurt Bitcoin, in a way. For every person that invests a GPU farm in an alt-coin, that's a GPU farm that could be put towards mining Bitcoins. And when GPUs are no longer profitable for Bitcoins (aka ASICs), it's still a GPU farm that could be sold for coins that could buy an ASIC (again, to strengthen the Bitcoin network).

So when I turn my 7970 off rather than switching to LTC, I do so out of a belief, rather than thinking purely about profit.

EDIT: typo

I am curently redeeming loyality points in coinlab, mining TRC too with another rig, just to mine BTC, is not profitable any more for me. Until when i get my litte single from BFL.

I'm still mining btc, but I'm considering mining some litecoins.  The exchange rate of 0.077 ltc/USD isn't bad. 

how about ppcoin? how's the demand like for those?

I hear PPCoin mining is worthwhile.  I'm not sure about the demand though.

Any of those alt coins have less inherent value than Bitcoin (which, admittedly, only has whatever value the market decides)
They are usually valued as x% of a Bitcoin.

It's basically a way to have more "wealth" in the alt-currency world, given that there are a fixed number of Bitcoins (by far the most popular currency in the "peer to peer cryptocurrency world")

Bitcoin is held by what, hundreds of thousands?

These alt coins are held by hundreds.

The US Dollar is like the Starship Enterprise (NCC-1701-D, if you're curious)
Bitcoin is a Volkswagen Bug.
Alt-coins are old, rusty tricycles priced "$1.00" at a garage sale, which are still there on day 3 of the sale.

i agree that ltc mining is sort of destroying the cards, atleast thats the case with me.
so far the best option is to stay mining bitcoin, and selling cards after asics.

cheers

Fixed That For Ya!

Haha! I was just about to say the D was always my favorite, but the E is def cooler.

LTC is so demanding on cards, that i could not even stabilize my 4 x HD 5870 setup, which runs just great on BTC, TRC.
