My rig has 4 x R9 290's (soon to be 5 x R9 290's when I get home) and since
switching to Linux yesterday the multiple threads work great for that little *oomph*
in computing power. Another way to look at my unique idea is to run certain GPUs
(multiple thread) on Ypool and then run the remaining GPUs (multiple thread) on
Beeeer, essentially devoting a GPU card to a pool. This is great for those with even
amount of GPU cards which I will NOT have when my fifth arrives today....

Just thinking out loud.... :-)

@mbender71: I've never tried that because I always tested with a multiple GPU setup. But I think it should work.

Whats the problem with running an ODD number of GPUs?

None at all. I was just saying that if wanted to mine at two different pools
at the same time by running two separate threads on each GPU (one to Ypool
and one to Beeeeer) then ODD number is just fine. If you wanted to devote
GPU's to the both pools and have an ODD number of GPUs then obviously you'll
have one extra card to either pool..... UNLESS you split that one ODD card with
two threads with each thread going to a different pool. It's just configurations
and honestly I'm not sure if there are gains at ALL to be made by mine both
simultaneously. Technically you would be mining against yourself since everyone
is searching for the same "next block" (unless they are sneakily doing the 51%+
flaw) but at least you're guaranteed some share time instead of loosing all your
share time if the block is not found. In a perfect world if only two pools existed
then you'd be getting shares for each block found.... but....... :-) :-)

again, just thinking out loud! no flames please!

Ah I understand, just making sure there wasn't some issue running an odd number of GPUs

Can confirm behaviours that others have seen.  Using Win7x64 and latest versions of 0.1.x and 0.2.x.  for 7850 and 7990 cards I use about 1% CPU with -t 0.  with -t 0,0 CPU increases to 50% and CPM is less than -t 0.  Also see miner using 500MB mem sometimes.  Not a big deal as am perfectly happy with results from -t 0.

From my post a day or so ago :

I think I finally have my 4 x MSI R9 290 rig setup under Ubuntu running clpts v0.2.2
with all the tweaks for now. Currently mining on Ypool at the moment and getting :

collisions/min : 15130
shares/hr : 1730

The total rig is pulling 1100w with a 20" box fan running on low to keep air circulating.

it pains me that I can't get the 64bit version of ubuntu installed on my intel board... I want to try ubuntu and clpts but it looks like the only linux version is 64bit so the 32bit ubuntu I have now will do me no good! jealousy!

After last updates from mircrosoft win 7 64 bit.. miner 0.1.4 got problems with my 270X... I had to reverse to 0.1.2.. catalyst 13.12.. my 290X is still ok. with 0.1.4

hi all, how can I fix this?
290X with amd_13_12_catalyst_64bit_whql
thx alot

Connection attempt failed, retry in 45 seconds
Obviously, the miner cannot connect to ypool.net. Is your internet connection OK?

my internet connection is OK, I can use other miners(such as yam's CPU miner or abs123's gpu miner ) connect to ypool.net.
only this miner doesn't work.
I alse tried v0.1, It cannot connect to beeeeer.org too,

I'm in china, dose Great Fire Wall block something?

Great !
Success install in Ubuntu linux 13.10 .
With 3x 7970  the  cpm = 7430 !

But not working in Ubuntu 12.04.

Nice!! Thanks for the info. I'm thinking of buying a couple R9 290 if I can't find any cheap 290X. The problem is that even R9 290 are in the $600 range......:(

No problem! Actually I managed to snag another MSI R9 290 from NewEgg earlier this
week and it came in yesterday. Yeah, the price gouging is getting rough as I paid $25
more for this single one than I did the other 4 from the same seller! I also got rid of
the 20" box fan and purchased 4 200mm 110 cfm fans to lower the noise level.

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.

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.

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!
