For me not keeping the coins on the pool and not registering to the pool is a + for the p2pools but on the other hand it requires having a wallet installed for each coin that you mine and for me that's a problem. I don't have wallets for each and every coin that I mine. Probably it also depends on the hash rate, which is low in my case Smiley.

XFX 280X :
voltage at which the cards are stable (at 1050@1500), usually 1.15V, but one of the cards required 1.175V
230W each and run at steady 730kH/s. Temperature is about 72-73C with fan at up to 80%.

Thanks, I am trying your values
E: 1050
M: 1500
V: 1.149V

and I get:
69C
510 khash
253 W

that is 2.02 khash/Watt


To get over 700 khash, I have to up' the memclock to
M: 1680
E: 1050
V: 1.149V

that results in
72 C
705 khash/s
293 Watt

that is 2.40 khash/Watt.


What is your hash rate at 1000@1500 ? Such big drops(you mentioned 510) in the hash rate are usually because of too much clock, so try lowering the GPU clock a bit. You should be able to get about 700kh/s at 1020@1500. Also how do you measure the card's power consumption ?

Well I was gonna order, but for now I will pass. Too much questions that are too easy to answer and still no answers  Roll Eyes. What happened with the guy that was living nearby and was going to pay them a visit ? Also can the other guy that had an e-mail response from them just show them this thread and ask them to participate. I suppose most of the buyers are also reading this thread so it's in their favor to answer here the questions that were asked and assure everyone that they are not scammers.

Here's how I do it on several XFX 280X :

1. After testing many different frequencies I found that my cards run best at 1050 core and default 1500 memory giving about 730kH/s. Yes some of them might be able to run at slightly higher frequencies but I think it is best to liming power consumption and temperatures instead of going for max performance.
2. Alter the voltage with Sapphire Trixx until I find a voltage at which the cards are stable (at 1050@1500), usually 1.15V, but one of the cards required 1.175V
3. Edit the bios and flash the cards with the modified bios using atiflash (under DOS).

My cards consume about 230W each and run at steady 730kH/s. Temperature is about 72-73C with fan at up to 80%. Note that every card is different and I found some of them running at higher or lower actual voltage at the same bios value. Also I found that some cards tend to show higher temperature readings without actually consuming more power, so this is definitely caused by differences in the quality of the cooling or how it contacts with the GPU.

Realtime NutLaw updates on the website : http://www.nutcoin.com/


I guess it will not hurt if I mine for several days from the beginning and hold the coins for several months if not years. A great looking site BTW !

We're prepping for a relaunch of sorts and hoping to have a lot more services running at that time as well. We're focusing on getting the new logo down first, then website, wallets, poker/dice and tipbot, and then pushing to get on more exchanges. I think coinedup was a little premature but I'm not worried. There has been a very solid response from developers looking to help out with this effort. And KittehCoin itself has some cool features that coins like DOGE and other BS coins coming out will never have (I'll let Lonestar speak more toward those features as he's ready to announce them).

We're working on building community and a solid presence, dumping coins at a low price is stupid. if you don't want them then donate them to help us grow kittehcoin: (official donation address) - KTiU2iYZyykHG9EBbYZ85ygpWNReXtZbFm.

Community: http://forums.kittehcoin.info

More to come.

Donated 100K. I hope we are going up !

This coin sounds very interesting. It's great to see that some effort is made to stop mine and dump.

I have a question: when I mine several mills in the pool will I be able to transfer them to my wallet at once ?
52  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] Crapcoin (CRAP) on: January 04, 2014, 12:26:27 PM
Quick question: I'm solo mining with 2 computers. But "Accepted" only increases on one of them and on the other it's 0. Am I mining with both computers or only with one ?

That's great but we need some more activity here : https://cryptsy.freshdesk.com/support/discussions/topics/62499/page/last#post-136520 !!!

Sorry, actually the right kitteh thread on Cryptsy is this one : https://cryptsy.freshdesk.com/support/discussions/topics/46461/page/last#post-136523

Why halving after 4 years ? After 4 years there's a good chance that nobody will ever remember this coin or even 4 months Smiley. Please make it halve after 4 weeks Smiley.

Hello I am using cgminer 3.7.2 for mining scrypt altcoins

but I've bought a new gpu

these are my settings:
Code:
cgminer  --scrypt --thread-concurrency 8192 --lookup-gap 2 --gpu-engine 1080 --gpu-memclock 1500 --gpu-powertune -20 -I 13 -g 2 --auto-fan --gpu-fan 30-90 --temp-cutoff 90 --temp-overheat 80 --temp-target 72 --no-submit-stale

cgminer:


Thanks for helping me out!

Below settings will give you about 730Kh/s :

--thread-concurrency 8191 --gpu-engine 1050 --gpu-memclock 1500 --gpu-powertune -20 -I 13 -g 2

Cheers !

"Serious" kitteh logo Wink. Just for fun :


Honestly its not the best of the best, but its the best logo ever Kitteh coin has had!

I agree

Personally, I don't like it. IMO logo should be funny.

OK. Here's my advice. If you are sure that you will get more GPUs later then you need to prepare a PC that can handle several GPUs. I found that a PC with 4 x Radeon 280X to be a decent performer. Each of these cards makes between 700 and 800Kh/s but most of the time between 710 and 750Kh/s. So what you should go for is :

1. Motherboard with as many PCI-E slots as you can find for a decent price. Those PCI-E slots could be of any type from 1x to 16x, because you will have to use PCI-E extender cables anyway for multi-GPU configuration.
2. Cheapest CPU you can find
3. Not much RAM, 4GBs is enough (probably less is also OK)
4. Any HDD
5. Video cards - Radeon 280x, 7950, 7970. Make sure you buy a model with unlocked voltage, so that you can undervolt them. An example of what brand you should not buy is - Gigabyte. While XFX, Sapphire, ASUS are OK.
6. PSU - this is critical. I found that with a good 1KW PSU you can run 4x Radeon 280x but ONLY if you undervolt them (well this also depends on the brand of the cards, and also on each card itself). By default XFX Radeon 280X consumes about 280W (again this depends on the brand and the default GPU voltage), but with just a slight undervolt from 1.2 to 1.15V power consumption falls to 230W. So a good 1 KW PSU like Cooler Master V1000 or Fractal Design Platinum 1000 can power 4 of these cards. You should get a device for measuring the power consumption. That is for ensuring that you are not over-loading the PSU.



If you find the information useful you can donate me some DOGE.
