ok guys so to elaborate on my problem, so i've clocked all the 750Ti's so they run the same clock and memory. The one that plays up is running at 33mv higher then the other 2, i am unable to under voltage the card in msi afterburner when the miner crashes, if i restart it the card pretty much stays idle and mines at around 4Mh/s Doesn't clock itself back up, which seems like maybe a driver crash. So i un-installed all my drivers, and re-installed them
even with new drivers the same card is still crashing the same, so the loop trick wont work as the card never clocks itself back up. Seems a weird one to me, and i dont have a clue why afterburner wont let me undervolt the card
who ever helps me get this sorted (besides suggesting returning the card, i will send you every heavycoin i have mined, at the moment its only 40, but i will send through more as i get them)
EDIT Ooo and the card will happily mine for ages when its sitting at 4MH/s
I dunno,but have you tried to use any other OC software other than Afterburner? And when the miner crashes,close it,go to device manager,disable and reenable the specific card. It'll reset the drivers,maybe that'll help?

i've tried evga precision aswell, that will let me over-volt but not under i haven't tried disabling the card yet no, i will try that if it crashes soon
EDIT
ok so disabling and enabling the card does reset it back to full mining speed
FIXED THE ISSUE may help others, so the card that was playing up, turned out to be plugged into a spare PCI 3.0 x16 slot. The temps on that card were higher then the others aswell
I had a spare PCI-E 2.0 x1 slot, moved the card there and its mining like a dream! so be warned anyone buying a rig, and planning to use the PCI-E 3.0 slots, they may not work!

I'm trying to make a batch file that restarts ccminer when it crashes, cause I cant figure out why it crashes. But cant get this command to work. Now I'm stuck :
I posted a solution at page 509.

There was a mention a while back of making sure your 16x slot was set to rev 2 in bios or something like that. Might check that out and see if it helps with that slot.

I only have the 3 cards so i dont need to use that slot, unsure why i used it in the first place if im honest.
Got all my clocks sitting at 1.2ghz now, mining at 11.5MH/s
i dont want to increase power usage too much, as the idea was to replace my 780 with 3 of these to save on power

Novice miner (and computers in general) installs 4 - EVGA 750ti and finds the following...
Waited on these for almost a month. Jumped from 1 - GTX660 to the 4 - 750ti.
Running Windows 8x64, CUDAminer 2014-02-28 x64 and Nvidia driver 335.23
All 4 cards are on powered risers.
CUDAminer set to auto (I think) -o stratum yadayada -0 (GPU clock +30 Mem clock +530)
Each card averages 260 - 265K with the total average at 1050K.
Temps lowest at 51 and highest at 61.
Watts at the wall showing through my UPS are between 390 and 450 and bouncy.
Overall I'm pleased with my first real project. Thanks CUDAminer.
Thought I would share. Searching around to get a bit more hashing without crashing.

Power wise, my main system running 3 instances of cccminer is sitting at 120W, not sure why, ccminer must be keeping my cpu running at full speed, even with cpu usage of 7%? My 3 750Ti's are pulling 150W from the wall, on a 80% efficiency psu, at best! Their clocked to 1.2GHz and mining HVC
giving a total load of 270W! With my 780 by itself i had a total power usage of 350W that's a power saving of 80W, or £110/$190 a year, one card will pay for itself just in power saving! not to mentioned the extra power i get from the 3 cards To pay power i would need to mine 74HVC a day, and anything extra is profit. All in all, their beast cards, and im looking to order a load more soon

in one of the algos (fugue?) we forgot to call MyStreamSynchronize after the kernel call. I just noticed today. But you're saying your CPU isn't clocking down even with CPU use at 7%? That's hard to believe. Christian

PICi don't have anything else running, thats my xeon which normally sits at 1.4GHz and only goes up to 3.5GHz maximum, (3.7GHz never gets hit without 100% load) power settings are set to cpu lowest power state is 5% your computer might be part of some botnet network You might be mining something you don't know haha i hope not

won't work. LTC is too big of a network, and I seriously doubt the majority is supportive of a hardfork.

no wallets on this machine, here's it with all my ccminers in one launch file PICso my cpu usage drops by about 3% and my cpu clock went down, even to the point of idling down to the 1.6MHz region for a few seconds every so often, i am still on it so it will idle down properly when im not. Yes i lost a small amount of hashing power doing this, but it seems to not keep my system fully clocked all the time. just thought i would throw it out there :-)

ok, so the power usage drove me to believe that my cpu was using the power, monitoring it now this is what i get No ccminer, my 780 sits at 5% tdp, total power usage 60W launch ccminer, my 780 goes to 27% tdp, total power usage 130W This is my ccminer launch config; (my 780 is device 0) ccminer-v0.5\x86\ccminer35.exe -a heavy -q -d 1,2,3 -o stratum+tcp://hvcpool.1gh.com:5333 -u wallet -p x -v 512 now the gpu load of my 780 is 0% but it is clocking itself up the second i start ccminer is it perhaps still telling my 780 it may be needed? causing the clock to go up? as the clock stays down when im using chrome, and doing basic desktop stuff Ooo and the power usage from my 780 is the same with 1 or 3 instances of ccminer at the same time

you know that with my system, I use less power than you to hash hvc (something like 80W per equivalent 750ti hashing power)

so your 780TI is around 5MH/s slower, and is that gpu power or total system? right now i can watch 1080p movies and use no extra power because of my gpu clocking up lmao
