Topic: [ANN] cudaMiner & ccMiner CUDA based mining applications [Windows/Linux/MacOSX] - page 581. (Read 3426975 times)

Since we're on the topic of temps,my card's doing something odd. I start cuda/ccminer and then OC the card. Fine,the core clock goes up and stays there as long as the mining continues. Then there's a small connection error and the MSI stats of all the clocks and temp drop to 0. On restarting,the mem clock goes back to the OC'd value but the core clock is underclocked,ie,even lesser than it's original clock. Why is this?

for anyone interested, here is the direct output of my webserver

soo now i just need to sort a port system out so i don't have to force a port in the code, and then just make it look nice on a page xD

Now after 5 mins of idling GPU is at 40C and VRM is at 58C. My system is stable until now and anyways I am getting a new rig in few days. At peak GPU was 78C and VRM was 95C. Although I must mention temps here are around 33-34C.

I did a quick search, and it seems that VRM temps can get pretty high no problem, for instance, my GTX 770 does apparently fine with 105 degrees, while I have read about some chips being fine with 125. I recommend doing some research on your card and act accordingly. And remember, if your set-up is stable, and you don't have any other issues, it is probably fine.

I will check and update here the idle temps

Yeh, it could be some bad thermal pads

what is the temp in idle ? Could be also some bad calibration of the sensor ?
Or some default with the cooler...

Can anyone else report there VRM temps so I can understand what is general value for this?

Dont count me on it. If your vrm is high and shouldnt be then maybe an RMA? Mine is watercooled so my temps never hit 40'C

I use hwinfo for monitering VRM temps. you can try it.

@bigjme

are you sure cuz that 98c got me worried but there is no way I can get it down except may be water cooling

Do you mine everything basically 'solo'? or is this just the way that you calculate.

I have never tried solo mining... but it would be so nice to not have to really deal with all the pools.

I have 6x 750ti up and running as of last night, so would you think that these numbers would be straight conversions (as estimates) of performance? Or is there some level in solo mining where you will never get your own block done?

Thanks for any input, I always find your charts useful.

actually i believe that gpu's are designed to run at 95'C without causing issues, the caps and vrm are usually designed for closer to 200'C i believe

98 is way too high for the VRM (well I think so... can't monitor mine on the 780ti)

@monsoon97

If you r mining for fun then its ok but if you want profit after paying electricity bills try to mine something profitable or use a multipool. You can see profitability and choose a multipool at poolpicker.eu

its for GPU my VRM run at 98 most of the time.

Ah thank you and everyone else for the help. Yeah I'm just getting started in mining and now I find it to be interesting. I heard about mining, but never got into it. My computer use is mainly my university stuff and some games, but during the downtime I leave it alone so I told myself why not I'll mine during the that time which is usually when I go to bed.

I have it set up like this:
CUDA manager kicks it with fans at 100% whenever the card reaches 80 degrees. If, for any reason at all, this does not lower the temp sufficiently, it starts clocking down at 81 degrees. And if that still does not help, at 100 degrees CUDA manager terminates the mining proces. I'm toying with lowering that last treshold to 90 degrees, but honestly, even the second line of protection was never needed, as my card only reaches the 80 degrees when I have had my windows closed for a couple of days, or perhaps one day when it is warm summer weather outside, or when it is really warm summer weather outside when I do have my windows open.

Normally it fluctuates between 73 degrees with fans around 45% during the night with windows open, to 78 with fans at 62% in the evening, when I have had my windows closed since the morning. But it is pretty cool weather, with a max temp of 18 degrees during the day, and during last hot period of a few weeks ago, I had to downclock my card a bit, as it was hitting the 80 degrees to often, and the fan was getting annoying.

As for the VRM temps, MSI afterburner doesn't measure that, but I never had issues, so I am assuming that's fine.

You can always google the given safe temps by the manufacturer and aim for that at max. I myself run a Gigabyte windforce 3x GTX 770, and I'm a part-time miner, I do mostly the same as you, and since my computer is pretty responsive during mining, even with the CPU assisting (i7-4770k), I can still do my university stuff, nicely optimized, or those that aren't big resource hogs, flash games and youtube vids, so I do that during mining as well.

Just ordered one.  Tried to do a similar deal back on Sunday but there was a problem with their system related to the add-on gift that prevented me from using the promo code.  Looks like they fixed it today.  Note, the rebate can only be applied to one card per household so if you want to get a second you'll have to go through another buyer at a different address.

GPU or VRM? Both?

If the temperature is too high, the card will clock itself down so dont worry about it
