[ANN] [PXC] Phoenixcoin v0.6.6.2 ~ NeoScrypt Original ~ 10 Years Old

[marada]

I have just compiled the CPU miner.

My FX-6300 gives 1.9 kh/s per thread = 11.4 kH total.

I am curious of other desktop CPUs.
Could some people post their results?

[catecoco]

Keep up the good work!

I'm using an Intel i7 4th generation 2.4Ghz and get around the same results.

Difficulty is skyrocketing, I'm wondering if someone already managed to come up with a GPU miner and is mining the hell out of this coin before releasing it.

 my i7-3820 @ 3.7 GHz is bringing in 12.3 kh/s  This in my eyes is way underclocked (really its stock)

My CPU water block chiller is under construction... I had a miss hap with my 1/2hp water chiller
 lets just say (my wife even though I told her+windows open on a nice day= bad condensation)
this was the chiller I was using http://premiumaquatics.com/products/aqua-euro-12-hp-chiller.html

sorta like this...

I had my 3820 stable @ 5.1 GHz

I have learn from my mistakes.. I'm getting away from the compressor and water sealing my whole rig....

My new cooling system will be using 4 peltiers, 4 old Apple G5 heatskins, 4 water block off the peltiers,
700 gph pump and an old Apple G5 case

 




Once I get her all done I will post my hash rate

Oh yeah and I solo mined the first block 400000!!

core i7 2600k@4.4 Ghz => 25 kh/s

[marada]

Thanks you all.

This is amazing: i7 2600k beats up all the rest 3rd and 4th generations....

But even my athlon II X2 has just also found a block

yes but it's overclocked 1ghz more than the stock clock.
Without OC I think it would be about 17-19 kh/s

If you compile it yourself, it is configured without assembly code by default. If you want it, configure this way:

Code:

env CFLAGS="-O2 -fomit-frame-pointer -DASM" ./configure

Compare your results with and without assembly. I know some AMD CPUs may deliver a little better performance without assembly code.

Congratulations again, you are a part of the Phoenixcoin history now

-----

2x Intel Xeon E5345 2.33GHz (Core 2 Quads basically) = 19KH/s
Not bad for an old 1U rack.

AMD A8-3870K 3.0GHz (Llano, 4 cores) = 9KH/s
It has also an integrated GPU which can do some other hashing like Groestl without much performance impact. Shall do NeoScrypt some day.

[lucazane]

on core i7 with ASM, it's almost 2 times faster

[marada]

If you compile it yourself, it is configured without assembly code by default. If you want it, configure this way:

Code:

env CFLAGS="-O2 -fomit-frame-pointer -DASM" ./configure

Thanks Ghostlander.
It did make a difference for FX-6300 and A4-6300, like +30%.
Didn't make any difference in case of older k10 based CPU (Athlon II X2).

I don't know if there is a point in playing with -O3 -march=native?

Could you update github instruction with this tip?
It only mentions ./configure CFLAGS="-O3" in *nix build instructions and readme as well.

[cisahasa]

so is there other neocoins outthere???

[NineEleven]

this
env CFLAGS="-O2 -fomit-frame-pointer -DASM" ./configure

make my xeons jump  from 20 khs to 39 khs
lololol

Can any Tell please is [Suspicious link removed]d or Scam what you think ?

Intel® Core™2 Duo processor P8600 (2.4GHz, 3MB L2, 1066MHz FSB, 25watt) on Lenovo T500 notebook hashes at ~ 1.5 khash per core using Win 64-bit wallet built-in miner.
Not really worth it so I'm not mining PXC.

Pentium 4 3.4GHz can do 1.4KH/s which is hardly worth the power consumed (100W+). Core 2 Duo is a not bad hasher, but notebooks are crappy miners in general due to weak cooling unless you edit ACPI P-states to reduce voltage or clock speed at least.

[ChekaZ]

Intel(R) Core(TM) i5-3570K CPU @ 3.40Ghz gives me ~15kh/s

No point if -DASM is used. -O3 unrolls all loops possible resulting in larger executable size which may affect performance either way. -Ofast enables -ffast-math additionally which is a set of non-conformant tweaks making no effect because CPUminer doesn't use floating point for hashing.

The following shows all optimisations enabled for -O3:

Code:

gcc -c -Q -O3 --help=optimizers | grep enabled

This is the difference between -Ofast and -O3 in case of GCC 4.7:

Code:

  -fcx-limited-range          		[enabled]
  -ffinite-math-only          		[enabled]
  -fmath-errno                		[disabled]
  -fsigned-zeros              		[disabled]
  -ftrapping-math             		[disabled]
  -funsafe-math-optimizations 		[enabled]

I'll update the documentation on GitHub later.

It's nice to see all this activity here for Phoenix Coin.  Hopefully it will bring in new investors.

Cheers!

Price is stilll super low to get in.

I bought some but I'm reluctant to buy more given there's going to be such massive dilution.  98 million is too much and I only invest a lot in a coin when I see a reduction in inflation and dilution.  The same principles when an investor chooses a stock to buy or even paper fiat.

The reason people are dumping paper fiat is inflation and dilution yet most devs don't understand nor care about this simple but important fact.
