You can run ccminer with the -e switch to turn it off.

-e I don't know what that is.
sp do you have the latest readme file on ccminer ?
Ps contributions coming soon. Wink

Got my new rig working again with 2 750ti....2 980ti .

EDIT: Electrical power line went down yesterday and burn out my new rig......... f#@&............ it will have to wait. Undecided

did you have some kind of power protection on that rig?

Didn't even have a chance to set that up......a long story short... didn't have the money to buy one yet.
I think its the mb.... I have a second on that I will be putting on the rig. Undecided

you can make a quick power protection box by using an old UPS, even with broken battery and low capacity, if it has some "surge protection only" plugs.

Crazy question - could i run (2) algos on the same rig in (2) separate instances. For example - (1) instance running X11 and (1) instance running (Skein2) on the same cards? What are the draw backs if any? I checked power consumption and there doesn't seem to be a change in power draw. Just wondering if I can break my rig that way? Thanks - pokeytex

YES YOU COULD--

I always ran 2 instances of CudaMiner on scrypt. The rigs would get slightly better total hash rate, and if one instance crashed, the other would go from 1/2 hashrate to full hash rate.

With mixed algos, you'ld be running separate threads through the cards. You could run 1/2 cards on one algo, and 1/2 on the other algo with "-a x11 -d 0,1,2" and "-a quark -d 3,4,5" on separate instances. You could run two instances with separate algos on all cards.

The drawback is probably that you loose efficiency, and the cards would run hotter, with the overall hashrates being lower. Have I done it? No, but you could try it and report. I don't think your rigs will break.

--scryptr

Pretty much... running the same algo usually it just splits the hashrate between the two instances. If you're running two different algos, the cards are probably utilized differently and you'll end up with a weird bottlneck somewhere that causes a loss of efficiency for both algos.

Ok - well thank you all for the informative posts above. I did try it and as you said - the efficiency was divided in half. I did decide to separate into (2) instances with the -d parameter and designated half of the cards to one algo and the other half to another. Thank you all for the info - poketex

Can't break your rigs that way but likely the driver will crash sooner or later. Or one algo will probably dominate the other so the hashrate won't be equal.

I've done it unintentionally, never saw any crashes but never let it run for any length of time or measure
performance.

Interesting thought. It won't break anything, it's just like running multiple processes on a CPU. But I don't think it
will work well. Most processors perform better with fewer processes with better cache performance and less task
switching overhead. Vector (SIMD) processors like cuda are even more optimized for doing the same thing over and over.

What you are suggesting would be suitable in a hyperthreaded environment where two threads share a common
set of execution resources. As long as the two threads require different execution units they can run simultaneously.
Unfortunately mining algos use almost exclusively integer arithmetic so the combined peformance of the two threads
would be the equivalent of one.

It might be worth an experiment to see what the combined performance is.

You can always run different instances on different cards if you want to mine two algos at the same time.

Can't break your rigs that way but likely the driver will crash sooner or later. Or one algo will probably dominate the other so the hashrate won't be equal.

Depending on what you want to achieve you might be better off dedicating a couple of cards to one algo and the rest of them to another.
Or you could just use a batch file which switches between the two algos periodically or as a failover.

The main benefit of the BTC MBs is the ability to supply 75W to 1x slots which are normallly limited to 15-25W, which makes
the use of unpowered risers possible.

All the motherboards can provide 75W thru the 1x slots, it's by specifications. The rest of the pins do not provide any power.
The difference is that the BTC MB can provide 75W to ALL the slots together.

I wouldn't ever pull 75w through the tiny little traces on a motherboard to all the slots at the same time, that's just a recipe for disaster, regardless of having a extra molex connector or two supplying juice.

As I said, my 2 rigs are runing perfectly, 6x960 and Pro BTC. Even OC'd. Now is 3 months already. And cheap cheap risers.

Everyone can easily test it. Do some search with melted ATX-connector, when mining touch the connector somewhere near those two pins.

I have tested some more. Release 74 is using more power and heat, so the card trottle and performance is lost.
My test was conducted in a closed case rig with a EVGA superclocked card (2x 6pins power)

but my dev card:
The gigabyte 970oc G1 comes with 1x8 pin and 1x6 pin and doesn't trottle and give bether performance in release 74 than 66.

SP_, all 5.2 maxwells do at least 1500MHz under load. In open case, limiting factor is TDP. Nothing to do with power pins.

-edit

Testing how far I can go with reference 970. You need to give this baby almost +300 to get there (1500). Around 10500 kH/s mining lyra2v2.

-edit2

Same settings with quark, hitting TDP and only hashing about 17200 kH/s. TDP mod is all you need if you want to get all out of these.

Yeah right... Roll Eyes

I have 6 maxwells 5.2 + 3x 750ti and only 1 of them is able to do a stable 1500+. All of them are over 1400 but no way to do a stable 1500 without a vcore rise.
Each of them was slowly overclocked by 20Mhz step. When I have noticed any crash of a miner I put it 20Mhz back. Gigabyte G1 970 was also benchmarked in some Windows "gaming" benchmarks.
Those are the clocks I'm using 24/7 without any stability problem and temperatures from 65-74°C:
gigabyte G1 980 1450Mhz
gigabyte G1 970 1560Mhz
3x Asus strix dc2oc 970 1440/1450/1480 Mhz
960 1411 Mhz
3x 750ti 1400/1420/1440 Mhz

Btw I don't care optimizing H/W ratio, because the electricity price is still low at my location.

With the r.74 I get more or less the same speeds as in r.66.

Yeah I was wrong there when I said all maxwells... Do you have a quality PSU? Custom fan settings? I like to run my rig(s) with overkill PSUs with loads somewhere in 50-60% area if possible. Mining cave

temperature is some in 22-24 celsius area.

All 5.0 I have tried have done 1400 easily, all 5.2 cards 1500, with or without power pins, with or without custom cooling. Maybe I have been just lucky...

I also tested one non-reference 970 card with quark. Both cards with one 8-pin connector, overclocking both to 1500 area. Hitting TDP so hard... Non-ref wins hands down 18200 - 17200.

"I wouldn't be concerned with drawing 75W from an x1 slot if the x16's weren't already fully loaded.

How does that conflict with your statement?

I think I misread that statement. I thought it meant that a x16 slot can provide more power.
Maybe you meant that you can power up to 2 cards from a standard motherboard? Then yes: I use to say that up to three is safe.

I think I know where we went off the rails. I was describing the intent of the 1x slot in the context of the entire PCIe subsystem
while you were focussed on the maximium power of a 1x slot in isolation. I also assumed that if someone (a miner
specifically) was looking at installing a GPU in a 1x slot they already had GPUs in the x16 slots.

We're all good.
