Hey everyone, I am new here and I tried searching for this topic but couldn't find much. I was wondering if anyone here runs GPUGRID on a laptop? if you do what temp you get? and does it effect the overall performance much?

I haven't noticed any performance drops doing regular stuff and temp is stable at around 72c to 76c (168.8F) but not sure if this is good for the laptop long term, it's my main machine and I need it to last another 3 years or so. lol

Laptop: Asus ROG G750JS (GTX870m)

Judging by the looks and its tech specs (dual independent fans, weight 4.8kg) this laptop is more like heavy artillery.
However, I would recommend you to crunch on it only when you are not using it, and you should stand vertically it on its left side (while the display is open), as this position would help to cool the laptop, since its bottom is not in contact with the desk. As far I can tell by the looks of this laptop, the intake of the cooler is under its exhaust, so maybe a laptop cooler stand would help more to cool this monster, than this side-standing position.
If you have 3 years warranty, then you should not worry. If they offer some warranty extension for this laptop, I recommend you to buy it.
You should regularly (monthly) clean the cooler's fins with high pressure compressed air.

The laptop itself is surprisingly cool to the touch even though its been crunching for over 2 days straight now, I can feel the heat behind where the vents are and yea its pretty hot but only in that area. I agree though I think need to invest in a cooling pad and maybe only keep it crunching overnight, I wouldn't be able to afford another laptop at this stage if this one brakes, warranty was only for 1 year and it already expired few months ago.

Does anyone know what typical crunch time should be on a laptop GPU for one of these

-> Long Runs (8-12 hrs on fastest card) tasks?

I managed to complete one so far and it took about 22hrs total. Seems bit slow. I wonder what they mean by "fastest card".

Judging by the GPU's temp of 75c on completion of a WU I think you'll be fine.

And DO regular backups on that laptop too!! Boinc can be very tough on laptops, I have lost 3 over the years mostly due to heat and HD failures. Laptop HD's are not designed to run 24/7 like desktop ones are, the newer ones ARE much better then even ones from a few years ago as some people transfer to laptop only lives and dump their desktops. But they are still aren't as long term reliable as desktop HD's yet.

Yea desktops definitely more reliable no doubt about it. That's another thing I was thinking about, I got BOINC running on a "Solid State Drive" which far as I know has a limited number of Write/Read cycles depending on the brand and quality etc... So I set (Request Tasks to Checkpoint at Most every ->> 1800sec) instead of the default 60sec. Not sure if this will make much of a difference though.

Well, I've been running GPUGRID on my Asus ROG G55VW for... 4 years? CPU + GPU 100% 24/7. Non-stop.
I even have the GPU overclocked.

Temps right now:

GPU 71C
CPU 82-87C

Regarding temperature: laptop GPUs are usually tuned for power efficiency, so there's probably not much you can gain. But generally you should be able to lower the GPUs power limit. It will adjust clock speed and voltage itself. There's a certain performance loss, but the GPU runs more efficiently, i.e. the heat output reduction is higher than the performance loss. There are diminishing gains for this, though, so I suspect it won't help you all that much. You can use GPU-Z to check the clock speed and voltage your GPU runs at. Those values would be interesting anyway. If it's running above 0.9 V you may gain something by lowering the power target ("nVidia inspector" should do it, or MSI Afterburner, EVGA Precision etc.).MrS

Wow that CPU temp seems pretty hot, but GPU @ 71 on full load that's really good for a laptop.

The future is here guys, anyone who wants a "portable" crazy powerful laptop and no worry about heat at all, check out (Asus ROG GX700) I believe its not out yet its just a prototype and will probably be stupid expensive too. It comes with a water cooling station haha! Watercooled CPU and GPU when docked, when undocked uses regular cooling. Which is fun I guess because you wont be doing anything crazy on battery power anyway. Oh and rumor has it its going to have GTX990 :)
