850watt psu for 2 gtx980 and 1 780ti doable ? (with a i7-3770 which doesn't use lots of power)

gpu's would be using probably 600w or more. factory in around 110w for full system loads.
Your cutting it close at 90% efficiency. The 980's have been known to use 200w when overclocked

New CN Windows build up at https://github.com/tsiv/ccminer-cryptonight/releases/tag/v0.17

Loaded with the magic compute 5.2 bullet, surely it will do one zillion hashes per second now.</sarcasm>

Mostly it's there just for the compute 2.0 copy-paste flub fix.

that, for sure, won't make the compilation faster 

[Amph]

I need to get a single 970 to test on.

you really should lol

and put that bitch on super oc mode, i want to see x3 750ti

I have 2x Palit GTX 970 delivered yesterday, not impressed so far, think they might be going for a return trip back up the river in a couple of weeks if nobody works any magic.

I am getting the following rates, per card, using driver 344.16, with +200gpu & +200mem

XCN 8mh
XMR 440h
X13 4.8mh
Scrypt Jane 6KH

Not tried BBR yet cause can't get 970's to work with Kopiemtu

System is drawing aprox 380w (not inc display) at wall, AMD quad core cpu so the 970's are using aprox 100w per card.

usually the cpu is in semi-idle, so it's more than 100w per card, or your system was completely at full(cpu included)?

because 100w for 4.8mh on x13 is good, on the same algo you need 125 with 750ti

trying to recompile with compute 5.2 might be worthwhile (so they say...)

850watt psu for 2 gtx980 and 1 780ti doable ? (with a i7-3770 which doesn't use lots of power)

Yes 165Watt x 2 = 330 watt for 2 980 + 250 watt 780ti = 580 watt .

Yes 165Watt x 2 = 330 watt for 2 980 + 250 watt 780ti = 580 watt .

plus the cpu and the rest of the system, adding to roughly 110W (to be safe), allow for gpu self and manual overclocking, 40w

total = 730w
850w @ 90% eff = 765w (psu efficiency often gets lower the closer to maximum you get)

~spare = 35w

just be careful djm, it may be a good idea to put a kill-a-watt meter on the system if you have one, then add one 980, then another and just see how close they get running some benchmarks each time

ok... I don't have one, but I might buy one. (In the mean time I can always run with either the 750ti or the 660... which is a bit counter productive though...)
However, I have a few spare psu (but not as good as the corsair...) Do you know what is needed to combine 2 psu ?
(I was able to found a sli bridge... )

honestly for now, take out the 780ti, and run the 2 980's
merging 2 psu's isn't too hard when using risers, but connected to a motherboard it can cause problems

you may have a cable for it already, its something like this

i used one when running my mining cards on a separate psu.

Just a FYI on the eff value, that value isn't the output from the PSU into the case, it's how efficient the PSU is at converting AC -> DC and thus it's draw from the wall. Your 850W PSU is rated at 850W and will always output that for the components into the case if needed but it would then pull ~935W from the wall. That being said I always build a ~10% safe value into my builds anyway so I'm not running the PSU at 100% all the time and, as bigjme pointed out, the closer to 100% load the lower the efficiency gets. PSU manufacturers should post their curves online somewhere to let you target the bet place to keep your PSU load wise as well.

yes sorry, eff when i quote it in that instance is usually a 10% safe guard as psu's are known to fail when ran full out. i put eff so none technically minded people understand easier
should have explained that better

What coin is best for 750ti Now ??

DGB is disable. ToT

try x-children, it seems the most profitable for now

probably not anymore after this post lol

[Schleicher]

I have compiled djm's version with sm_52 support.
Fearless GTX9xx (Windows-)users could try this:
http://www.sonstiges.org/stuff/ccminer-djm-vs2013-sm52.zip
Since I don't have any GTX9xx card I can't say if there is any difference.

It has been compiled with Visual Studio 2013,
so you need the matching runtime stuff if you don't have it already:

you can try coca-cola coin when it gets launched... I am pretty sure it will be huge if there is a lawsuit (and vice versa...)

no not yet, will do that a bit later (I have downloaded the drivers and installed the new version of cuda 6.5)

is the 3dmark demo version on steam is ok for testing ?

Should be. I've found some results anyway but want to see what you get
