Google chrome trick? I've had chrome opened up [to follow the pool] and closed and don't recall seeing any difference.

What I do see is when cudaminer autotunes to t5x24 I get my best rates, it also pushes the TDP to between 97-99%.

I have not managed to make a working .bat file in which I can force that setting. Flag switches just don't appear to work for me.

+215/550 is not bad.

Even at 300 khash you are only talking about $1.30 a day with LTC and the price is dropping. It really is becoming a waste of time.

While true, I holding and not selling. Currently mining Doge. I will begin to mine LTC and hold as well. We shall see. I have very little invested atm. You gotta spend money to make money.
 
Vertcoin is the way to go if you want to GPU mine now since ASIC's are coming out (or ARE out) for Scrypt.

Vertcoin is ASIC resistant and Scrypt-N. Alot of GPU miners just jumped on it recently.

https://bitcointalk.org/index.php?topic=404364.0

Right now vert.rapidhash.net is giving out a 2% reward bonus with no pool fee's to the first 150 blocks.

Usually don't promote pools, but free 2% bonus is always nice!

Ya, I know not all of them are worthwhile, but as long as the worthwhile ones are on the list. About the only one I don't see it on is Mintpal.... but oh well, there's always an odd duck in the bunch. Meh, give em time and Mintpal will come around too.
 
That's odd, running cudaminer 2-28 version under 86 and my system froze solid.

I never thought that was possible with 7-64 and a quad Haswell.

I had chrome loaded up but that was it.

From what I have read, Scrypt-N won't be ASIC resistant for very long. There is already one company (Bliss) claiming their ASIC can mine both Scrypt and Scrypt-N. Also, there is a interesting thread over on Bitcointalk talking about this very thing: https://bitcointalk.org/index.php?topic=528586.0

Does this truly matter, though? Especially when the developers of these coins have basically waged an outright war against ASIC's and will have no hesitations in forking to whatever is necessary to thwart them?
 
We honestly need a completely different algo (like say Keccak/SHA-3) to take up the fight for the GPUs.

Re-inventing Scrypt isn't going to work. All it may take is a firmware update on these ASICs to run modded Scrypt algos.
 
Anybody mine DarkCoin or its x11 derivatives? If any coin is popular/profitable enough, ASICs will be developed for it regardless of what it's using (x11, Scrypt-N, Scrypt Jane), it's just a matter of time. Looking to mine a more ASIC resistant coin but not sure what's the best route.
 
Litecoin was out in October 2011. Scrypt itself was formally published in 2012.

Only now are the ASICs catching up. SHA-256 got bushwacked for more quickly.

We are definitely on the right road with the emphasis on memory requirements / constrainments.
 
GPUcoin is also scrypt-n and you can use the coins to buy gpus from their online store.

You can't just fork coins whenever the mood strikes you. The instability causes investors to shy away from those types of coins as they can't be sure of their long term stability.

Not too mention that if you have multiple forks you essentially have multiple versions of the same coin.

So many people think it is as easy as sliding in a stick of memory in your traditional motherboard. :confused:
Click to expand...

They also think making a flexible ASIC is easy.
It's really not IF you make the ASIC do what it is intended to do and that is run one complex set of tasks really fast at low power using the least amount of silicon possible.
There are flexible ASICs already out there. They are called CPUs!
And we know how well those mine in todays world....
Believe me when I say, it would only take a very small, well calculated change to an existing algo to make ASIC logic written for that algo, completely worthless for mining it.
And FPGAs are just too expensive and do not have the logic gate count to be the end- all flexible device to kill mining for GPUs.
 
From what ive read, its only the larger memory size required to hash scrypt-n that differentiates from regular scrypt. If ASICs manufacturers already figured out how to circumvent regular scrypt, seems to me the battle is over. They have done the hard part already. Whats to say they cant continue increasing the memory size on the ASICs to keep up with scrypt-n??

Also, everyone needs to remember that as scrypt-n increases its memory size our GPUs slow down more and more. Less coins in your wallet.

No, I think a whole other algo needs to be looked at to really slow down ASIC manufacturers. Scrypt of any kind wont cut it.
 
I've been out of the ASIC world for a couple of years now, but I seriously doubt the memory is a part of that die.
Ram and memory in general eat up silicon fast. And gigabytes are rarely built in.
I don't know the exact answer, but how much memory is usually built into a CPU die for cache?
If it was small area wise OR cheap Intel and AMD would just include 4/8/16 GB right in the package.
If it's just memory size that's the difference, then yes, a smart built-in controller will let you add more external ram.

They really don't even need to release new ASICs with more memory, they can just make it swappable by the user. :D
But yeah, the future is X11. Tested it out this night, and goddammit it's awesome. Lower power consumption, lower heat, lower wear and tear and much higher performance than Scrypt (N). Plus it's very hard for ASICs since it keeps rotating algos. :D
 
I'm thinking of switching over one of my miners to x11 but not sure which coin I should mine. Darkcoin? Hirocoin?

They haven't circumvented regular scrypt, they've just built a chip with just enough onboard SRAM to fit the algorithm on. The Gridseed is estimated to have 128KB of SRAM for each chip, while the Alpha spec sheets indicate it has at least 16MB of SRAM for each chip that's only capable of several hundred kilohash/second.

Make the n large enough and ASICs no longer becomes practical to build.

What makes Hiro any different than DRK?
Click to expand...

Functionally? Very little.

I went with Hiro because I'm hedging on it gaining popularity. I can't advocate anyone else taking the same risk unless they can justify it - but if I'm forced to choose between two coins I pick the one with the lower difficulty to maximize my potential future returns. Opportunity cost principles and all that. Basically, I'm mining the lesser known coin and making a bet on it raising in value later, thereby optimizing my returns/khash.

Could I bust on this hedge? Definitely! Will I? I'll let you know. ;)
 
Gotcha, yeah it seems like it is brand new, I didn't even hear of it until you posted about it.

Reading the ANN thread it seems like there was a problem or something on launch with the diff being stuck at super low levels so a select few people got hundreds of thousands of coins in mere hours? Essentially making it a premine? I liked the coin until I read about that :\.

I tried mining Hiro but I couldn't get the miner to work with my 7950. Worked great on my 280x, but my 7950 wouldn't mine at all.

Has anyone posted settings for different cards?

GPUs operate with memory bandwidth at hundreds of GB/s. Is it possible to create boards with add on RAM that can operate at such bandwidth?
 
Sure. Not simple and not cheap, but the "width" of the data bus is what makes the highest bandwidths possible. If it were just a 16 bit wide bus then most likely not.
That's why GPU chips are the physical size that they are. Lots of connections required.
 
I'm not even checking coinwarz anymore. It's too depressing. I'm just focusing on my pool project now.
 
Were I to guess I would say there is a Titan currently mining Greececoin on Dedicatedpool. A single user is hovering around 220khash. Highest I've ever seen.

There's a user with double that on Litecoinpool, and on Coinotron i've seen even bigger.

I appreciate this, but those people are usually mining for profit - do you see them just switch off to new coins ad-hoc?

I think someone with that much khash would be smarter to solo mine and stay under the radar.
