You only need to add one line, "12" will get you OC and fan control but only on cards with a monitor attached.
I've seen attempts to fake a monitor on a second card but nothing has worked for me.

http://www.phoronix.com/scan.php?px=MTY1OTM&page=news_item

Not really true so I found out on my setup. 8 & 12 did nothing only after I added "Coolbits" "5" was adjusting the fan speed enabled.
So I think it may depending on the card type and or driver used, some may have to play with different numbers for each type setup or driver used.
I just never removed the others and paste those because they did work for other setups.

Edit: have you tried making a dummy plug for those cards without a monitor?

https://rumorscity.com/2013/12/06/how-to-create-dummy-plugs-for-your-graphics-cards/

We had to use these back in the day before Nvidia got there stuff together in there drivers for folding at home rigs with muti video cards.
I still have some laying around here. lol

I had only tried software hacks but this looks interesting.

The coolbits pattern changed, either with the driver version or card generation. I have the latest driver and
maxwell cards and "12" works for me. "5" is an old code, the phoronix article explains it.  Either way you
can set all the necessary bits on one line.

I'm using a pretty old driver 304.125 because its the only one I could get folding to work with without errors in Linux.
So its probably why "5" is the only one that works in this setup. I still fold once a month with my main server rig
for the $10 EVGA Bucks, saves me 120 dollars a year off my next EVGA buy. I didn't really buy much last year so
I had enough to fully pay for the GTX960SSC with what I had saved up. 750k gets the 1st 5$ 1.5 mil get the 2nd 5$

Folding@EVGA http://forums.evga.com/EVGA-Folding-Year-8-m2301653.aspx
I been folding for over 15 years way back before we had the type of power we have today to do these things.
I only cut back on my folding after getting into Cryptocurrency and F@H made a 4P rig almost worthless after I just payed $900
for the motherboard alone. So I put all my hardware to make money instead of spending it to keep up with folding projects.
It is a good cause.

About the bits I had read that all could be on one line but was unsure if they needed spaces or comers in between each
since there were no examples shown and the post wasn't very clear. Thanks for clearing that up.

linux guys, check out the kopiemtu thread on litecoin.org. i solved the overclocking multiple cards issue around page 60-65 or so.  i run driver 346.59 and cuda 6.5

[dominuspro]

linux overclock:
As a complete linux noob I lost 1 afternoon messing with xorg.conf file. I could enable OC for first gpu only. Then luckily I found nvidia-xconfig command.
This command made the trick:
nvidia-xconfig -a --cool-bits=28

It generates a new xorg.conf.
-a enables 1 screen for each gpu
coolbits 28 enables nvidia oc + fan controls in xserver settings and should also enable voltage control from the terminal. It is meant for maxwell cards. Older could need different approach.


Tested on latest Lubuntu with nvidia 355.06 driver and some messed up cuda sdk 7.5 + 7.0

I hope it helps somebody

cuda 7.0 ( .28 ) and 7.5 break just about every hashrate except x11 from what i can see ( and x11 is down by around 200KH compiled with them also ) ....

but i will try this when i get the chance to change settings / systems ...

ill be in full swing again tomorrow - so a great deal needs to be done ... debian based systems ( like ubuntu ) may work differently than fedora - so i will try and have a look at how this functions for fedora tomorrow ...

tanx for the info ...

tanx hashbrown ...

its a mess when it comes to a 'simple' way of enabling all those features with linux ...

nvidia - as large and equippped as they are - really dont put a great deal of thought and effort into making it a more simplified approach to facilitating the linux community ... amd are a lot worse though ...

your help with this has been priceless ...

tanx again ...

I know about cuda issues... I just tried following the tutorial on ethereum cuda thread to start slowly with linux
Then I managed tho compile also other miners and then started messing with overclock... I'll probably have to do a new linux install to a smaller usb stick and it will be cuda 6.5 then

I forgot to say that it does not need any display or dummy plug connected into the second graphic card.
cheers

Not much but I guess every little bit help. Wow it charges a fee every time you send now?
I don't recall it doing that before on BTC, just every now and then if I recall right..

Thanks for your support. I have added more hash for the gtx 960 (quark.) the other cards are also abit faster.
If you can build yourself, please try release 62+ (github)

Keccac512 with less instructions

[sp_]

My EVGA superclocked gtx 950 mines quark at 8.3MHASH on factory clocks. Release 62

I have the same card. How far does your boost by default?
Mine goes to 1380. I got shit ASIC, only 66%  

Don't have gpuz installed. Not sure. In the latest from github the EVGA gtx 950 superclocked is peaking at 8.5 MHASH release 62+. So I managed to push it up  150-200KHASH this weekend.

@dominuspro,  I see you're running a newer driver than me. it seems nvidia likes to change the method of enabling OC on all GPUs with each new driver release. I had to go thru the same research because kopiemtu used to use driver 340.xx and the OC method was different even back then.

At least it is possible to oc
Anyway I feel much more confident overclocking in Win enviroment with afterburner

I currently have crossfired R9 270 cards in my computer. I am pulling them out and rebuilding my mining rig. I will be adding 2 R9 290x cards to make a four card rig. The R9 270 is currently the best overall card to mine ETH, getting 18 MH/s with each card, whereas reported hashrates for the R9 290x are about 21 MH/s. So obviously 2 of the R9 270 is better than a single R9 290x for this purpose, but I want my rig to be versatile with regards to mining other algos.

So.... that said, I am writing in this thread to say that I am debating whether or not to get a Nvidia card for my computer to replace the crossfired R9 270 cards.  I had ordered an R9 Fury X, but delays in shipping caused me to cancel. I am now down to deciding on either a single R9 290x Vapor-X or the Gigabyte GTX 970 G1.

This seems like it would give me the best versatility between my mining rig and my computer when mining various algos. Power consumption is not that much of a concern, but keeping temps cool in my computer case is a big plus that has me leaning towards getting the Nvidia card. I am only undecided at this point because from most available comparisons of hashrates that I can find, the R9 290x seems to greatly beat out the 970.

 I probably have said more than I need to, but what say ye? Is the 970 the better choice?

Edit: Okay, wrong thread for this probably 

[Slava_K]

In commit 980 i have a problem whith text visualisation in Miner Control (last correct is tid xxxxxxxx, thats all...). No hash. No gpu №. but miner is working. Cant test hashrates...
On nicehash miner is faster. I go to close credit for my 980gtx and do payment for grate gob!

[sp_]

Edit, I forgot to check in something. Will do it now.


I have merged som changes from another coder called Nelson, but some of the code doesn't work so I had to revert parts of it.

I think the best will be to do a clean and a full rebuild with the latest sourcecode.

[sp_]

I have submitted a fix. please test.

[Slava_K]

Work fixed  . Night to test in real world...

For sale, available, or private?

[sp_]

A rewrite of lyra2v2 with shfl up instruction is old news. nicehash payouts for the lyra2v2 algo has gone down from 0.8BTC/GHASH on launch and down to 0.35BTC/GHASH making it less profitable than quark even with an optimized miner.

*pretty picture omitted*

Yea, fortunately it's not that hard to add --diff 0.5 on the command line. Just hoping they give a bit of a heads up before changing it if they ever do.

For sale, available, or private?

Undecided, private and for virtual **** waving for the time being. Not very impressed with the OSS + donation model so far, pretty much quit for while but we'll see. Let's just say I didn't exactly drown in donations for the CN and spreadX11 miners, then a certain somebody comes along with some optimizations and decides to sell them for 0.1 BTC. Why bother.

Zero shuffles in this mofo, would run on sm_32 straight as is and 30 for sure after replacing ldgs with regular loads. Probably lower but CBA to check.

Meeeh, actually mining VTC instead of dumbassing it and mining for 0.33 on Nicehash seems to be on par with Nicehash quark profitability, more or less. Curiously enough Westhash is paying 0.6 for l2v2 and it's likely that somebody's still making profit on their orders at that price.
