OMG, 79C. My card when overclocked need to be kept below 56C to be stable ...

Yeah - I definitely wouldn't feel good about that temp... I shut mine down if they hit ~74c (my 660's). I never have to worry about my 750Ti's - they rarely ever hit 50c.

[ol92]

80°C for a GTX980 is a normal operating temperature. I have a similar setup (two GTX 980 evga) and with quark algo and a reasonable overclock ( +100 but they are already oc : so I ran them at about 1500mhz @gpu) they are between 77-80.

Those mining with amd card are used to go higher!!!

I've mined at 94C for months ;-)

we have destroyed about 16 x gigabyte 280x oc cards with those temps ...

1 x gigabyte 750ti oc ( powered ) has a fan that is shutdown due to temps as well ...

thank God they have a 3 year warranty ...

maybe the 290(x) is different, one of them run for about a year at 94C and is still fine, overclocking and all :-)

it is waiting for warranty to end )))

All my 970's have been running at around 79/80 over the winter, kept the house lovely and warm!

My OC'ed 970's are doing 14500-16000 kh/s mining quark and staying around 79/80 with the windows open.

they can ... and they do ... the few 290x cards we had were super hot - but they worked so well ...

the 6990 cards would go just as hot and still run like they were on ice ...

but unfortunately - when you have so many in a single frame and so many frames in a single space - it gets pretty hot pretty quick ...

they will fail in the long run ...

but they hash real hard ...

I strongly recommend high fan settings for anyone that can afford the extra noise that this will cause. Modern day GPUs can certainly run very hot without any trouble, heck, the 980 specifications allow for 98C temperatures, however, with cards at full load for prolonged periods of time (aka, mining), higher temperatures will simply cause higher failure rates.

Failure rates vary greatly, and everyone's experience is their own. In any case, with lower average temperatures, one should expect less failures over time. For most of us, I think we tend to replace the hardware (upgrade, new toys, etc) before the GPUs fail definitively - but there's certainly exceptions now and then.

My "hot" 980 runs 80% fan, and the "cold" one 70% fan (both reference cooler designs), and both of them sit at 70C (+/-2) temperatures while hashing non stop. I think that 80C is perfectly ok for these cards, but if you can run them cooler, all the better.

Note that a lot of the GPU failures are caused by VRMs running too hot (most times, they are much hotter than the GPU core itself). Cards with backplates should do better in this respect, but only slightly.

Happy mining heating!

Look in minercontrol forum branch. Westhash and nicehash changes in config.

Look in minercontrol forum branch. Westhash and nicehash changes in config.

all dns names are under nicehash.com now - all with the same ports as before - all with the new prefix of the algo.usa/eu ...

not a bad dns naming convention ...

quark.usa.nicehash.com:3345 or quark.eu.nicehash.com:3345 ... and so on for the other algos ...

its all here in their thread ...

all the donation links will be directed to these same stratums and are under testing as we speak ...

links will be coming soon - for sp initially ...

Good job. Interesting to see that the 780ti is outperforming the 980. Will you share your changes or keep it private?

[mendoza1468]

Hi,
i want to know on westhash what is worth to pay more :
Exemple :

Quark at 30 mh/s = 0.7072 BTC/GH/Day
lyra2 at 2.4 mh/s = 3.0539 BTC/GH/Day

Is there a way to calculate?
I think the Quark will pay more because of the speed no?

Second question what is MA - norm ? A new algo?

Thanks for the help
(2xgtx970)

[myagui]

@mendoza1468:

Simply put, just convert your hashpower to units of GH, and multiply that by the paying rate...

Quark at 30 mh/s = 0.7072 BTC/GH/Day -> 0.7072 * 0.030 = 0.021216 BTC/day
lyra2 at 2.4 mh/s = 3.0539 BTC/GH/Day -> 3.0539 * 0.0024 = 0.00732936 BTC/day

As far as your other questions, you should really spend some time reading their FAQ.
Everything that you asked is very well explained there.

yes it is a little strange, the 780ti runs at 95% tdp while the 980's and 750ti runs rather 65/66% (which could mean that the 980 could do a lot better)
will have a look at the ptx, the answer is probably there...

For the moment those changes will remain private

true however the 780ti is way behind the 980 on neoscrypt which is more demanding at that level

The reported temperature of the GPU is coming from the core itself and there are usually no temperature sensors on the Mosfets/VRMs which always have higher temperatures as they are not directly connected to the heatsink (some cards do have additional sensors there which you can read with GPU-Z). Granted, these modules also have a higher maximum operating temperature than the core itself but their lifespan is based on the operating temperature and the duration at those temperatures. If you haven't, I recommend picking up a cheap infrared thermometer to see for yourself. A 750 Ti running at 60°C at 70-80% fan speed will still have VRM temperatures around 70-80°C depending on design (how much air gets to the parts) and overclock. Which is perfectly fine but if your core is running at 80-90°C the temperature of the VRM/Mosfets might be so high that they will probably fail within a few years. This site is for motherboards but should give you an idea about estimating VRM lifespan: http://event.asus.com/mb/5000hrs_vrm/

maybe the 290(x) is different, one of them run for about a year at 94C and is still fine, overclocking and all :-)

The 290/x series were designed to operate at up to 95c at which point the fan ramps up to whatever your maximum threshold is and once it reaches whatever you set the maximum to it starts downclocking to stay under 95c. AMD said they were perfectly alright operating at those temperatures. That was what they were engineered to do. That doesn't apply to 280/x series though. The conception that it's 'too hot' is based on what people know about other GPUs besides those.
