Beeeeer Vs YPool

A little off topic but not so much when NaN's incredible miner only works on these two pools.
I used to mine @ Be^5r a week ago but it seems like they are either offline higher than usual
and now the time between solved blocks is increasing (perhaps due to less miners and technical
difficulties like DDoS). YPool has been pretty darn steady the past three days until yesterday when
clpts says it disconnected, will wait 45 seconds, and then just exit out to the command line.

NaN : How do you handle disconnects from the server? Do you only try one time after 45 seconds
         and then just exit out? Last night it happened twice to me and fortunately insomnia had me
         restart clpts by hand. Perhaps I should script it to keep trying. I seem to recall someone else
         asking about fail-over as well and I suspect this is due to the issues these two pools are having
         lately.

Everyone : Which pool do you prefer using, YPool or Be^5r? YPool works so well but I dislike pools
                 that are too large in fear of block control.
Did you use last version ?? i'm run on win8 it normal not onetime reconnect and out

Yes... I'm using v.0.2.2 and it's been working wonderful until last night. Right now I'm giving be^5r
a shot but goodness, they are sometimes like 3 hours between block solves! Still waiting. Who knows,
perhaps my ISP was just having problems last night and it was me.. but still I was surprised that clpts
would just exit out (cleanly).

I have seen someone talking of getting 3.5K CPM on a 280X. Has anyone ever heard of that?

BTW, AMAZING job on this miner! Keep it coming!!
W7-64-Cata 13.12 / 280X / 1125 core / 1500 mem / 3450 cpm
this 280X-cards are a dream for windows-mining with this fast NaN-miner

my 290X does about the same - NaN suggested a failure in windows compared to linux for this 290X-numbers
Wow 3450? I'm only getting 2450 on Windows 8 / 14.1 beta drivers...
I'm Got on win8 with 13.10 280x/1125/1500/3475CPM it very Great Performance
Mmm I'll have to try the stable driver release. What flags are you using?
did you run with 2Thread and -a 1 ??

I think I've seen this error before after the AMD drivers crash. First I would check to
see if the AMD drivers are seeing all of your video cards properly :

aticonfig --list-adapters

If you see your adapters then I suggest shutting down your machine and restarting.
Strange things happen when the AMD drivers fail and the only way to get things back
on track is a shutdown/restart of the box. Hope this helps a little.

(I'm running Ubuntu 13.04 x64 kernel 3.8.0-35 with AMD Catalyst 13.12 + 5 x R9 290)

Bug reported to developer.

I have 4 r9 290x running on ubuntu 12.10. The driver is 13.12 linux. I tried to run clptes but have an error message.

error in xptMiner/clInit.cpp, line 96: Method clGetDeviceIDs(...) failed (errorcode -1)

Any idea to fix it?

beeeeer.org and ypool.net have different share difficulties, so everything is ok. At the moment the beeeeer client shows a share target of 0x00fff..., which translates to <shares per minute> ~ <cpm> / 256 and for ypool we currently have <shares/h> ~< cpm> / 512 * 60 ignoring statistical uncertainties. Please note that the share difficulty can be changed any time by the pool operator.

Well that makes the math much easier... so essentially the shares/minute/hour seems to average out to equal CPM based upon the difficulty of 256/512... so we really should only be judging by the CPM as a comparison when we're trading numbers with folks?

So now the rig is as follows:

5 x MSI R9 290 running Ubuntu 13.04 & clpts v0.2.2.
Currently mining on Ypool at the moment and getting :

collisions/min : 18908
shares/hr : 2192

The total rig is pulling 1300w.


Hey I was just thinking about this... 2191 is your shares per HOUR right? which comes out to roughly 36 a MINUTE? this seems awfully low to me if I am reading it right... I was tinkering around with 6 x R9 270 cards and was getting 8600 cpm and 33 shares per minute... and thats after it was running overnight for a good 12 hours so it wasn't a quick burst...

I'm wondering if there some difference in whats displayed in windows 64bit 0.1.4 at beeeeer and the version you are running on ubuntu over at ypool? I mean am I accurate, or are you accurate? if we're both accurate, something can't be right lol.

[STATS] 2014-Feb-14 17:54:47 | 8593.08 c/m | 33.35 sh/m | VL: 603 (97.89%), RJ: 13 (2.11%), ST: 0 (0.00%)

am I translating the sh/m correctly into sh/h ? 33.35 x 60 minutes = 2001 shares/hr for me?

which would mean at half the cpm I am almost equal to your shares?

Sometimes I wish english was my first language, I always feel like I am wrong.

========

(answer found: turns out ypool and beeeeer have different difficulty settings, so shares won't always match)

You indeed ARE a lucky person to have grabbed those 290X's for so cheap! Everyone
is in the mining craze (which is good/bad) and so many of the cards are hard to get,
well except for the 290X as the price is so high that profitability isn't there for the
performance.

First question is if you bought a reference cooler design or did you buy a GPU card
with an advanced cooler design, such as MSI Gamer card with twin fans and special
radiator? The reference design cooling system is awful and it will be very hard to
keep them cool while running high performance tweaks. Fortunately, NaN has very
optimized software that provides GREAT performance with much less power consumption
than cgminer (not a super fair comparison since one is MOMENTUM mining and the other
is SCRYPT mining). NaN keeps pushing the envelope though and each revision is faster
but does consume a little more power. Still WAY better than SCRYPT performance though.

The key to high performance is great power supplies (I use two Seasonic 860 Platinums)
using the proper PSU coupler (amazon for $29) and more importantly a good plan for
cooling. First step is to forget mining inside a case. Get yourself large plastic crates or a
wireframe rack. Next is to space out the GPUs properly! The farther apart they are, the
better. Actually the BEST thing you can do is make sure there is nothing in front of the
intake fans on the GPUs, that is the fans are pulling in fresh room air and NOT preheated
air from the GPU next to it. Having all the GPU's next to each other produces the cascading
heat effect where the GPU on the furthest right runs super cool as nothing is in front of it.
The next GPU gets pre-heated air from the GPU to the right of it, and so on and so on until
the furthest card on the left is running super hot. Same principal applies in cases but from
top to bottom.

Having said that, use some ingenuity to keep those GPU's cool! My goal is to keep them
under 80C while running full steam and better yet, keep them 70C or lower. It *CAN* be
done but requires some thinking *smile*. Keep the GPU fans running 85% or higher as
that is your first line of defense (closest to gpu/radiator) to keeping temps down. Sure it's
loud but you're mining.... PROTECT YOUR INVESTMENT.... second line of defense it to keep
cool air in front of the GPU fans.

Good luck!


Yea I got lucky and I managed to get these 4x R9 290X for $599 ea off Amazon.

Aside from my 4x R9 290X I have 3 GTX 780 which are pulling a measly 6500 cpm together....I bought those last year before I planned on mining. *shrug*

Now I'm just creeping around Amazon, Newegg, Tigerdirect, and Ebay until i find some rightly priced R9 290(x).

Edit: What temp are your cards running at? I just bought some 1x to 16x powered PCIE adapters and I think I'm going to pull out all but one of my GPU(s) from the case. The second card is making my top card run at 80C - 85C at all times with Fans @ 100%.....while second card stays at 60C-65C.
