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!

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 ...

Wink ...

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

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 ...

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.

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.

have gpu clocked +228 also drug the fans to about 3000 rpms and left them there..

Intensity set at 24


getting around 19Mh each as well

I tried using the NvIdia inspector and adjusting the P2 memory settings but it did not seem to help or hinder it at all so I don't bother anymore

great news ...

westhash ( or just nicehash nowadays ) have allowed our server ( the test server ) to be listed on their whitelist ...

this means that the disconnection and ip banning will no longer be an issue ... at the very least the ip banning is no longer a problem ...

with the granitecoin / crysx donation link - disconnection happens intermittently but comes right back up so it seems that when the connection becomes idle it does a reset every so often ...

as of this week - im personally full time on this - so by the end of the week we should have the mining donation links back on to test on this server ...

the donation links will be initially all sp's links to his btc address - so if you would like to donate to sp by mining - please help us test this ...

if all is well - we will look at a permanent server to hold the mining proxies for the devs donation links ... as well as ours - as all this infrastructure does cost money - and any help would be appreciated ...

our farm will be intermittently offline for short and long periods during the next few weeks - possibly months - depending on the rebuild of the infrastructure / workers / servers ...

will start a new thread soon so we stop cluttering sp's thread - and have all the info in one place if you are interested ...

tanx all ...

My gigabyte 970OC is doing 15,8 at stock clocks. I don't think the 980 will do 20 at stockclocks. you need to overclock. I haven't tested in a while though.
If you have a 980 what numbers do you get people?

Stock clocks/overclock

Build the latest version 50+ for the best speed.

@SP_

I have a pair of 980's doing ~19.2MH each, with just a moderate overclock. I'm currently running a much earlier release, as all the recent ones have either been unstable, or performed worse - and I've not had a chance to test around much with the different intensities on those.

I might try building the latest version tonight to report back on the speed with that one and the exact clocks I'm using.

Happy Mining!

Hi,
Does anyone have the following problem while trying to mine Neoscrypt:

Try to use lower intensity e.g. "-i 14". Do you have 1gb mem card?

I deleted the post. Stupid "-p d=0.02 " parameter made problem. Solved...

I don't know this one...what is 'fresh' algo? Is it GPU, CPU....?

Thanks

GPU.  The original coin to use it (I believe) was Freshcoin, I'm not sure what other coins use it.

ahh, I didn't see the clockrate..

1510 is a very high clockrate. my 750ti's are normally running stable between 1300-1400. How much power in the wall are you using rednow?

Ahh, I have no equipment to measure. It is running stock voltage 1.125 and with std tdp bios mod to 65.5W (http://cryptomining-blog.com/1014-how-to-increase-the-geforce-gtx-750-ti-power-target-limit/) gpu-z is showing from 50 to 66% TDP.
The card has no additional power connector and is powered from my old mobo pci-ex 1.1 port.

@quark:
You are getting around 6MHASH on the 1gb 750 with 512 shaders. A overclocked GTX 980 has 2048 shaders and can do around 20MHASH.
6*4=24MHASH
This meens that the 980 doesn't scale good enough. If we only take the shadercount the gtx980 should do around 24MHASH when mining quark. With some more work and tuning, I think the gtx980 numbers can be improved.
stock 980 @ ~1300 mhz ...

stock 980 @ ~1300 mhz ...

so at 1510 mhz it actually would do about 24 mhash ...
