[XMG] M7M CPU mining discussion thread

[Erkallys]

hi im planning to mine magi using a 4670k. will it gain decent profits? or i should just buy at the exchange?

What hashrate do you have with this ?

a 4790 mines 30 kh so im guessing a little lower than that

With my i5-3570k I got 60 KH/s and  6XMG/day so with 30 KH/s he should have 3 XMG/day.

shouldnt i get much higher than you? 4670k > 3570k right? did you oc your procy?

[vince232]

hey this is my config minerd.exe -o stratum+tcp://xmg.suprnova.cc:7127 -u <username> -p <password> -t 7 i only get 20 kh/s i use 4670k.

is there something i need to add?

Yep, he's better. But I haven't oc my CPU so I don't understand where does the error com from.

Guys,
I tried wolf0's v2 miner at ubuntu 12.04 x64 with nonce-pool and got (boo!!!).
But the m7magi-cpuminer-v2 works fine at same pool.
Can some explain  where is the problem?

which version do you use?
also you should use minerd-x64-corei7.exe for your cpu

The m7magi-cpuminer-v2 is an old one now (still works, but much slower) and the latest source is at

https://github.com/magi-project/wolf-m7m-cpuminer-V2

which I assume is the one you are having problems with. I remember having a few problems myself, compiling it for Windows.

I seem to remember solving it by copying files from the m7 sub-folder to the root folder - all the files starting with sph_ and ending with .h, but I am not sure that this actually was the fix now - memory fades.

4790?  This 4790?
https://cpubenchmark.net/cpu.php?cpu=Intel+Core+i7-4790K+%40+4.00GHz&id=2275

Yes, you should definitely be getting way more.  I can match that score with my bulldozer, but never denied that it takes a hefty overclock to do so.  At stock 4.0 Ghz I get 15 Kh/s per thread.

What about https://github.com/magi-project/m-cpuminer-legacy-v2 ?
I am using that one.
Tried to compile wolf-m7m-cpuminer-V2 but it fails when i try to build it.

sweet-spot-0.9.9 --> very good  

This is real nice TonySon.
Thanks for the update.

not exactly XMG mining topic but highly related, do you guys have any cpu cooler to recommencement? i am using the intel's default cooler and i was wondering if there is any cheap solution to drastically improve the cooling of my i5-2500?

With TDP of 95 watts?  Anything fairly decent will do.  I don't know what you've got for choices but if you can get anything with a wide rad like this...

http://www.memoryexpress.com/Products/MX47174

...for under  $100, you're laughing.  95 watts ain't much so it's all up to you and what deal you can find.  Try Kijiji, I found a Nepton 280 there fo $60!!  That's this one...

A decent water cooler such as either of the two mentioned previously would be more than up to the job. The first one looks remarkably similar identical to the Corsair H110 that I use for a CPU with TDP 225W which works just fine for that and would possibly be overkill for your CPU. You might find that a smaller model such as the Corsair H55 would suffice.

The Intel i5-2500 is designed to run hot with a safe operating temperature of 72 deg C, somewhat higher than average.

Hope this helps

yea it helps, you just made sure that my concerns are more than real. I get 72 C with -t 2, you don't want to know what is happening when i am going -t 3 or -t 4 (i think i have seen 97 C once and i had to close it before start smelling )

I am sure i need at least the Corsair H55 but it's way more expensive than i though, it's probably a good investment neither the less.

[Amph]

apparently there is still no gpu mining for this? or it's only private? this coin is old enough there should be one already

cryptonight all over again i think, but with less profit

Ouch!  Sounds like the current cooler is a bit off or needs a refresh on the thermal paste.  In any case, cooling is good, more cooling, better, can't have enough!  But enough about liquid nitrogen, reality!  That Corsair H55 is about the cheapest you can get, and was the first liquid unit I ever got.  Now doing a good job cooling my 7950.  It is however, about the cheapest unit you can get.  Entry level on liquid is still about $60-$70, but it's worth it!  I've never looked back and wouldn't use anything but.  The performance on even the low-end units like that Corsair is superior to anything but the best (and most very expensive) air units.  You will be spending about $50 anyways on a superior air unit.  Other advantages... that Corsair unit replaced a Coolermaster V10.  You know how big those things are?  This big...

http://article.techlabs.by/img/article/8934/IMG_5583.jpg

Ye-gads!  Aiee!  And the Corsair unit outperformed it.  Never looked back.  Here's a few minor factoids for you to help you choose your new toy (and you are gonna get one, right?)  Your rads are measured by width, so a "240" will be 240mmX120mm, a 280 is 280mmX140MM, and so on.  Heat dissipation is mostly by area so if you can get a cheap 240, gravy.  Think of it as basically boosting your cpu, because you'll get a lot more performance out of it.  I'm SO glad to have my water unit back in action because now instead of worrying if I"m pushing it, I'm happily cranking away at 5.0 Ghz.  20% more machine!

I play with "magi-minerd.git" miner. When I add parameter --extranonce N to the command line, miner starts to print debug messages about "Get work" blocks. I tried to add parameter "--quiet" but it has no effect in this case. Is it a bug? Parameter --extranonce N is troublemaker, without it, miner is silent.

Code:

# ./minerd -s 5 -t 1 --url http://localhost:55881 --userpass user:secret --extranonce 26342 -q

--------------------------------------------------------------------------------

Other issue with parameter --extranonce is that short version (-e) is rejected by minerd as invalid option

Code:

--extranonce
(-e N) Extranonce to displace miners using the same getwork server

# ./minerd -s 5 -t 1 --url http://localhost:55881 --userpass user:secret -e 26342
./minerd: invalid option -- 'e'
minerd version 1.0.2
....

BTW, I miss a parameter to print minerd version, like -V, --version

Hoi!

I have a few spare intel xeon phi cards. 59 cores.

Is it possible to use for mining during the night when they are not in use.

Will i get decent hashrates ?

I have a few spare intel xeon phi cards. 59 cores.

Could you benchmark my Cuckoo Cycle PoW on one of them?
I'm curious how it performs with more than 40 threads.

See the source code at https://github.com/tromp/cuckoo,
and try running make speedup...
