choose barebones computer (FREE Assembly & Testing Included)

Barebones w/ Intel Core i5 / i7 (Socket 1150)
  w/ Core i5 4670 (4 x 3.8GHz CPU - 6MB Cache +1200MHz Graphics)
  ASRock H81M-DGS
  Systems - CPU Fan Only
  2GB DDR3 1600MHz (1 x 2GB - Single Module)
  500GB 7200RPM SATA3 6gb/sec - Hard Drive
  Standard Value Mid-Tower Case
  400 Watt Power Supply
  Standard - Build, Burn-in, Test & Ship Out in Approx 3 to 5 Business Days
  Barebones - 1 Year

$359.88 shipped, they don't have a good choice of hard drive, but no labor fee.
I5-4670 is good in benchmark

If replace the CPU with  I5-4430, $333.88.

1 GB is enough ram to do the proof of work and adding additional RAM will not accelerate the process by more than .05% with almost no gains beyond 2 GB... make sure there is room for OS and wallet app.

The proof of work is structured so that by the time you use 768 MB of ram (entire nonce search space) there is a 99% chance of finding 1-2 potential hashes.

Once you exhaust the nonce search space you clear the RAM and start over.

Increasing CPU speed helps until the bottleneck is the memory bus and is worthless beyond that point.

If you have less than 768 MB of ram your performance falls exponentially such that 512MB of RAM cuts your performance down to 10% (SWAG) of what it would be with the full amount of RAM.

Thanks,

Today, DDR3-2400 Ram is not expensive, and MB support up to 3000MHz overclock (although higher cas latency). And considering I7 cpu can only saturate 50% DDR3-1600, improving cpu speed/thread is the key, right?

Is 768M for a single core/thread or entire system?

It is so hard to build a proper miner before release. Do you have plan to get into miner business?

Does this means for the I7 with DDR3-1600 combination, cpu is the bottleneck?

If three or more I7/equivalent work with DDR3-1600, memory speed will become the bottleneck?

Does the memory size matters? I suppose it will increase the speed also. Or 2GB is enough?

Have to say your signature is really annoying, too shining.
128  Bitcoin / Project Development / Re: Momentum Proof-of-Work Bounty - 30 BTC on: October 29, 2013, 05:42:53 PM
What exactly is the "memory bus speed"? Is the RAM speed like PC12800 or the QPI become the bottleneck?

Will larger CPU cache size be able to help a little bit in the performance?
129  Bitcoin / Project Development / Re: ProtoShares Bounty - 30 BTC Start Mining BitShares in November! on: October 24, 2013, 05:47:32 PM
What will be the initial difficulty at the launch? And how fast is the adjustment of the difficulty?

2) When BitShares is released the genesis block will contain all of the unspent output balances from ProtoShares chain.

Does this mean the ProtoShares mining will stop at the moment of BitShares releasing?

Will the already MINED ProtoShares be converted to some value of BitShares or the holders can profit in terms of BitShares operation?

Another Chinese crap which is "CPU-only", remember YAC, YBC, and many other chinese "CPU-only" coins? They publish a CPU miner, and the dev and their friends are all mining with a secret GPU miner, all these coins are from scrypt-jane variations.

It's an old Chinese trick, everyone knows now

Sounds like that shitty Blakecoin is one of these. Still no gpu-miner but the hashrates/difficulty are insane.
Are you kidding?
Current Difficulty   0.00190757
Network Hashrate: 221.000 KH/s. This is the speed of ONE 7950 card in Srypt-Jane.
I believe this proves that no one now mine with GPU.

LOL, you do not even know what is Scrypt-Jane, ever heard of a thing called Nfactor?
134  Bitcoin / Hardware / Re: How Much is a 50 GH/s BFL Bitcoin Miner Worth on: October 11, 2013, 05:09:06 PM
I would say 30% increase is optimistic, 20% is unrealistic.

sounds like another mastercoin.

you know, if you have a white paper and some more promise, you may get BTC4000..

138  Alternate cryptocurrencies / Altcoin Discussion / Re: 【ANN】【PGC】Pangu coin - launched! on: September 17, 2013, 05:22:38 PM
My theory:

- it's scrypt-jane
- rpc has been disabled in this pre-compiled client or password is hardcoded
- coin creator has his own version and mines with ybminer (scrypt-jane)
- after a while a v1.1 client will be released on github, when he mined enough

Why I think password is hardcoded? When I create a pangubi.conf and point the miner at the correct port I set in the conf, it gives an "invalid credentials" error rightaway. If I point it at the wrong port, it takes 5 seconds to give an error. So something is listening but doesn't accept my credentials.

I don't think I ever used the word "scamcoin" on this forum but I have a feeling I'm close to using it.

exactly same here
139  Alternate cryptocurrencies / Altcoin Discussion / Re: 【ANN】【PGC】Pangu coin - launched! on: September 17, 2013, 02:01:26 PM
start with
Pangubi-qt.exe -datadir=db
but put datadir default in ..roaming/pangubi ....
and dont wont to read  configs from pangubi.conf ((((((

I also find trouble to run in server mode.

here we go, thanks.

Am I correct that all mined coins stored in the same privkey? If true, that is awesome.
