I noticed slight drop in performance in the new 1.5.48 version on quark. I have 3x750Ti and previous 1.5.47 gives a bit more.

what settings do you have? ...

bathrobehero,

What is the advantage for mining when increasing the TDP of a 750Ti via a flashed BIOS?

I imagine that it allows a higher overclock and therefore higher hashrate. But, I have had a PNY 750Ti OC for over a year, and I never flashed it. I never saw anyone posting any hashrates for algorithms that I cared to mine that were significantly higher than what my card would do (with my particular card's stock BIOS - OC maximized). Sure, maybe a less than 5% faster hashrate than my card, but that just didn't seem worth the risk and effort.

Am I correct or mistaken?

Actually the 750ti throttles at stock tdp (meaning when it reaches 100%tdp, it gets clocked down a bit to stay below the 100% tdp target...) increasing the tdp would allow it to be more stable regardless of the OC (also it is the voltage which needs to be increased for higher overclocking)

[tbearhere]

Trying to figure out why ccminer doesn't crash on this computer but does on my rig when stratums go down and I have a 2nd pool backup and it crashes at the goto loop command . I just noticed that one card on this computer is the super clocked factory setting no oc needed is on the mobo and it stays at 1350 750ti sweet spot. So overclocking may be part of the problem. But it still shouldn't crash IMO.

:loop
ccminer.exe -r 1 -R 5 -a quark   -o stratum+tcp://anypool
ccminer.exe -r 1 -R 5 -a quark   -o stratum+tcp://anypool
And it crashes right here at the goto loop and says ccminer.exe can't be found. So it freezes right there.
goto loop

And if I click off the notification only it starts mining again without manually  restarting ccminer.

@tbearhere:

I'm not using loops myself and I don't have any crashes, but seeing as the error message is that 'ccminer.exe is not found', have you tried adding the full path to ccminer? Could be that the crash is somehow messing up the set working directory for the batch file. If you are already using the full path at launch, then the suggestion is moot.
The result would be something like:

:loop
<somedrive><somefolder><somesubfolder>\ccminer.exe -r 1 -R 5 -a quark   -o stratum+tcp://anypool
<somedrive><somefolder><somesubfolder>\ccminer.exe -r 1 -R 5 -a quark   -o stratum+tcp://anypool
goto loop


Good Luck!

@myagui
I'm very amateur at this. Could you explain more on <somedrive><somefolder><somesubfolder>\ please? Thx

[myagui]

I'm assuming that your launch batch file is placed on the same folder as the ccminer executable.
For sake of example, let's say that ccminer.exe is stored in this folder:

c:\miners\ccminer\release99\

So your batch file would be right alongside ccminer.exe (placed on the same folder), but for completeness, you would call the executable with a full path string, like so:

:loop
c:\miners\ccminer\release99\ccminer.exe -r 1 -R 5 -a quark   -o stratum+tcp://anypool
c:\miners\ccminer\release99\ccminer.exe -r 1 -R 5 -a quark   -o stratum+tcp://anypool
goto loop

So now just replace c:\miners\ccminer\release99\ from this example with whatever is the actual location of your executable, and there you go. No clue this will help at all though, just a quick experiment that cannot hurt.

If you want to place the batch file in a location separate from the miner executable, you can just add a folder navigation command at the loop start, like so:

:loop
cd c:\miners\ccminer\release99\
c:\miners\ccminer\release99\ccminer.exe -r 1 -R 5 -a quark   -o stratum+tcp://anypool
c:\miners\ccminer\release99\ccminer.exe -r 1 -R 5 -a quark   -o stratum+tcp://anypool
goto loop

You might need to tweak the path strings depending on how long your folder names are, or if there's any spaces on them. Adding one more example in which one folder name is using a space - note the added quote symbols (")

:loop
cd "c:\miners\ccminer\latest release\"
"c:\miners\ccminer\latest release\ccminer.exe" -r 1 -R 5 -a quark   -o stratum+tcp://anypool
"c:\miners\ccminer\latest release\ccminer.exe" -r 1 -R 5 -a quark   -o stratum+tcp://anypool
goto loop

Yes it's in the same folder and I'll try to understand what you just posted and give it a try. thank you myagui

When I'm mining straight for BTC, I just use MinerControl:
http://cryptomining-blog.com/tag/miner-control/

It may take a while to fully configure, but I think that it is definitely worth it, for the ease of use (basically, set and forget). MinerControl takes care of switching between what is paying the most, and also switches when a pool is dead/offline.

When I'm mining a specific coin, I use a batch file with a single call to ccminer. I don't ever have a crash, so I never cared to make a looping system. This configuration does not include a backup pool though. I babysit my miner when I'm not using MinerControl.

Here's what I'm running right this instant:

@echo off
C:
cd "C:\1. Cudaminer\cudaminer-2014-02-28\x86\"
C:\Windows\System32\cmd.exe /C start "CACHE GPU-0" /HIGH /AFFINITY 0x5 "C:\1. Cudaminer\cudaminer-2014-02-28\x86\cudaminer.exe" -a scrypt-jane:CACH -o stratum+tcp://cach.catcoin.cz:3333 -u <user.worker1> -p <password> -i 0 -L 8 -l t64x4 -b 4096 -m 1 -q -d 0
C:\Windows\System32\cmd.exe /C start "CACHE GPU-1" /HIGH /AFFINITY 0xA "C:\1. Cudaminer\cudaminer-2014-02-28\x86\cudaminer.exe" -a scrypt-jane:CACH -o stratum+tcp://cach.catcoin.cz:3333 -u <user.worker2> -p <password> -i 0 -L 8 -l t64x4 -b 4096 -m 1 -q -d 1

This batch file runs 2 concurrent cudaminer instances - both get launched at the same time - as it is using a "start" parameter. The point of using 2 instances is to have a separate worker for each GPU, which improves the reported hashrate for this pool/algo. This launch type also let's you easily tweak priority/affinity settings, which is useful in certain instances (and specially if you are also CPU mining).
IIRC, I had to set the shortcut to such batch files with the "run as administrator" option enabled, otherwise priority and/or affinity would not stick.

Thank you myagui. I downloaded KBomba's  miner control some time ago and didn't set it up yet. And my main concern is a backup pool right now. Looking at your info now and thx for your time helping me.

on yaamp skein is 2x lower...

[flipclip]

if quark is back on with yaamp and has no issues - would it be better to mine there? ... we find that westhash seems to have less downtime than yaamp ...

#crysx

Past day or so westhash has offered better payment with quark (or if yaamp was more, it was only slightly).  As of now westhash with quark is beating yaamp with quark.  I think you'd be safe leaving it on westhash (though keeping an eye on payment spread every so often).

Jim Jefferies is hilarious. He's one of my favourites along with Louis CK, Doug Stanhope, Jimmy Carr and Lewis Black.

GPUTHREADS--

Mining with the latest Windows release (v48) on Win 7 x64 with a GTX 960 SSC, with the settings of "-i 22 -g 4"' I am getting realistic hash rate reports of ~9.5Mh/s locally, and 8.3Mh/s on WestHash Quark.  I think the gputhreads switch is working.

However, with single-threaded "-i 23.7", I get about 10.6Mh/s locally and 10-11Mh/s on WestHash Quark.  It appears the card can crank hash more efficiently single-threaded.  I miined for about one hour with gputhreads.       --scryptr

just woke - so catching up on posts ...

but one of the largest nvidia farms? ... really? ... i would not have thought so ...

jim jefferies - need to make time to watch this ...

so much errands and running aroudn to do today - on a saturday ...

by the way - ALL the nvidia cards run ccminer-spmod ... the amd cards run sgminer-dev version ( and wolf binaries ) ...

Question: how are you computing performance from multiple devices?

is this a general question? ... or directed at me? ...

my apologies but i dont fully understand that question ...

could you please specify exactly what it is you are asking? ...

increase in hash rates but it fluctuates.
the main problem is, it goes to some dead state in multialgo
840M ---> quark around 3150 that was 2900 in v45

Code:

ccminer.exe  -a quark -r 1 -g 3 -i 22

840M ---> x11 around 1530 that was 1440 in v45

Code:

ccminer.exe -g 3 -i 19 -a x11

Try to run without -g and with default -i. And then check on the pool. I suppose the numbers on the pool will be better without -g ...

By the way ... what laptop model do you use? Is cooling system adequate for mining? What are 840M temp? I'm looking for a laptop with Maxwel GPU for my work. Would be nice to choose one capable for mining when it will not be in use ...
