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)

That's a difficult question, as it depends a lot on the laptop cooling & build quality. That GPU temperature is fine, but it'S surely heating up the other components around it.

Personally I wouldn't use an expensive laptop like that and wouldn't recommend it either. That's why I'm stil using a Thinkpad from 2008 - it just won't break, which is nice :)

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".

By "fastest card" the GPUGrid team is referring to the various graphics cards and the fastest of these would currently be either the Titan X or the 980Ti, both of which are for desktop computer systems.

Definitely try to keep the laptop as cool as possible. When I first got into BOINC projects a few years ago it was on a laptop. I managed to cook it to death after a while by not giving it enough airflow and not cleaning it regularly. It was a learning experience, but a costly one.

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.

Even more of a reason to DO BACKUPS!! When a SS drive dies it is usually the onboard controller that goes, not the actual drive, BUT it also means there is no way to access the data because the drive controller is dead!!

Don't worry about the SSD write cycles (reads don't matter anyway). They are limited, but it should take you many years (probably >10) to reach even the limit set by the manufacturer. Afterwards there's likely a lot more usable life within that drive (at least from the perspective of write endurance). You can check this e.g. with Crystal Disk Info (freeware).

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.).

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

I installed nVidia inspector to adjust fan speed but its grayed out for some reason, very strange. It sounds like its going at about half its full speed I know it can definitely go much faster. I been experimenting with program called "TThrotle" it seems to work well with BOINC and it lets you set limits on what temp you prefer to keep your CPU and GPU under.

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

Yeah, it is hot. But, it's still about 20C below the maximum lol. The laptop is at most warm to the touch... ASUS really did itself with their cooling solution.
I should do a re-pasting of the thermal paste soon (I've read that factory pasting is awful). That should drop it a few C.

I leave it on 24/7 to avoid as much as I can the "cold to hot, hot to cold" expansion/contraction, which in my opinion, is the worst culprit to computer lifespan.

the problem I have with TThrottle is that it can only switch between "on" and "off". If the power state you're running at is too high (i.e. maximum turbo mode, full throttle) and you use TThrottle to get temps under control, you switch between doing nothing and running inefficiently. Your hardware doesn't know it should run sustained and efficiently.

It would be far better to reduce clocks & voltages and reach a sustainable power state. The limit to this scaling is only reached once you can't reduce the voltage any further (threshold voltage reached). That's why Intel introduced "duty cycling" in the new Skylake CPUs - but it's only used after the traditional voltage & clock scaling has reached its limit.

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 :)
