Does anyone know a YAC config for gtx 780 classified? Using t9x21 overclocked at +100 core clock right now and getting 4.4-5.5 khs.

[cwizard]

I've tried google and in site searching and keep coming up empty handed for some reason, I've got 6 gigabyte OC 750ti's and USB risers and can't get windows 7 or 8 to be happy with more than 4 cards.  If I go 6, 2 will show yellow bullets.  I would greatly appreciate some links or quick advice around this, I know it's something I am missing.

Thanks

Eric

Problem was user error, I forgot to plug in the 6 pin power at the PSU end for those 2 cards.

DURR.

I'm finding that running 2 cards per instance of cudaminer is working very well!

Hem.. Mine only ogt 6.5 pick with this. Any idead of whats wrong?(I have a case with bad airflow, so I controled the temp at 76. Maybe that is the reason?)

that may be why, as nvidia cards overclock themselves till they hit the thermal limit so limiting it down would limit the hashrate aswell.
but i think the thermal limit of my 780 is only at 80'C. then again it is a watercooled card so may have had a lower limit then normal cards?

Thanks, I overclocked at +135.. maybe its a litte too much? just had servel freeze and I had to force shut down.

[bigjme]

Yeh, i would set it back to stock and try it again

I allow 95 deg C temps. I have a case of bad airflow too...

Sir, when I say bad airflow, I mean one fan of the 780 is nearly covered by cables.. Nice work on the recent miner update though, hope to see another of you wonderful work soon! 

[bigjme]

Miner update? Did i miss something?

[z1103246]

Miner update? Did i miss something?

Well, not that recent.. refering to the 2-02-2014 update

[antonio8]

Late to the party but is the ccminer for groestl not compatible with 750ti's?

28-02-2014  I guess...

Ahh. I thought my morning "read about cudaminer when o wake up" had failed me xD

Will using, say, a 1000W PSU hurt? Is too much a bad thing? I already ordered it.

you will lose a tiny amount of power efficiency (probaby 2%) but aslong as your power price per KwH isn't stupid it wont make too much of a different.
Which 1000W did you order? i just replaced my old psu with a RM1000 and it made a huge difference

as an example, 2% * 1000W = 20W an hour

in a year you would be using an extra 175.KwH which even at $0.20 per KwH its only an extra cost of $35
so yes its $35 a year more expensive but your psu is under less stress and in theory should last longer

For people wondering about what size psu to buy, this might be confusing. 

Just because you bought a 1000w psu does NOT mean it will be using 1000w.  Too much power is never a bad thing.  In fact, if you buy a 1000w but your system only draws 500w, it could be more efficient than getting a 600w since some models perform best from 40-60% load.

I'd say in general for most 80+ Gold and Platinum's, they perform best around 50-85% load depending on the model(There are many variables).  My 6xEVGA 750Ti FTW rig pulls 530-540w mining regular scrypt which puts me around 82% load on my Gold certified 650w.  It's a bit higher than I'd like but I believe my psu only drops 1% in efficiency when compared to 75%.

Anyone having any luck with UTC now that the numbers went through the floor? Or would this even work over there?

My 750ti's were getting like 75KHash/s each after the increase. What are you getting with your mods and 750s after the change?

Before the change in N-factor over the past day or so, I was getting 60kh/s on UTC (and 300kh/s on normal scrypt so you can roughly judge my overclock on the the card).

The setting for UTC I was using before the n-factor change was...

-l T5x11 -b 4096 -i 1 -a scrypt-jane:UTC

What command line switches and OC on the card were you using to achieve 75kh/s?

At the moment with the same switches I'm only get 1.35kh/s

Apparently I was exhausted last night, and mis-stated the total as each card and not total.

I am getting ~19.10 khash/s for each card after the switch, and 75.80 khash/s total for 4 x 750 ti cards.

That being said it still seems more than what you posted, so here is the config I was using if it helps you.

Sorry for the confusion.

cudaminer.exe -a scrypt-jane:UTC -m 1 -i 0 -H 2

Autoconfig chose T31x1.

Thanks for posting this, I will give it a try later

Do you guys think the efficiency of 2x750ti is better than 1x280x...
 - in Scrypt?
 - in Scrypt-N?
 - in HVC?

[liomojo1]

I don`t know , but 6xti750 on my asrock pro btc , burn 590w minig scrypt N=9. It is not  that good. i don`t know these about these 38w , but may be they are not so 38w. 

[bigjme]

I might change my psu that my cards are on soon just to see what they pull on a 94% efficiency psu.

Right now i am measuring 50W per card at the wall and the psu is at maximum 75% efficient. Which would drop the cards down to around the 40w range with an extra 19% efficiency
