Hi all.
I would like to know the minimal Nvidia graphic card on notebook to run notlong WU of GPUGRID.
Thanks in advance

The only thing you can do with a laptop is put an External GPU, but don't expect the same performance than in a internal one.

Many tanks to Toni and Damaraland.
Have a good day.

I have recently joined to GPUGrid a laptop with an nVidia GT630M in it, and it is crunching fine.
It took 39h 33m to crunch a NATHAN_CB1 workunit, and 32h 14m for a KASHIF_HIVPR.
It runs cooler with GPUGrid's workunits than PrimeGrid's, but good ventilation and frequent air dusting is needed.
I've put some extra rubber spacer under the laptop to ensure proper airflow.

I highly recommend against running distributed computing on a notebook. They don't have the heat dissipation capability for it. I tried it once on a Dell XPS and it significantly shortened the lifespan of the computer.

A little OT:
I am crunching on the HP 6735b GPU/CPU for 3 years 24/7 without any probem. GPU is weak HD 3600 (only Collatz). I found the best cooling in position of NTB as a letter "A". 3 month cleaning period to clear dust is necessary.

If you can actually get proper cooling on it and your temperatures don't run too high, then it could be viable. Just monitor it very closely. If temperatures skyrocket, you are either going to have to perform surgery on your laptop to improve the cooling, or just abandon the idea for that particular piece of hardware.

Out of pure curiosity I let my laptop (with a GT630M) crunch a NATHAN_FAX4 wu. I've overclocked the GPU to 800MHz (it runs at 670MHz by factory setting). It's finished in 3 days 20 hours and 13 minutes (332000 secs). The GPU is 76°C, and the CPU is 82°C.

That processor is rated for 85°C max for PGA and 100°C max for BGA. Either way that's pretty warm.

Since this wu finished, I turned swan_sync off, and cleaned the cooler. At this moment the GPU's temperature is 62°C and the CPU's is 61°C. There is two HDDs in this laptop, their temps are 44°C and 38°C (they were 49°C and 42°C while the NATHAN_FAX4 was running with swan_sync=0). The motherboard's temp is 65°C.

This notebook (others too) self protect itself by reducing the CPU core clock to 800MHz, and reducing the core voltage at the same time, when the CPU core temperature reaches 82°C.

Really interested in the idea of external GPU. I am crunching on a desktop with Twin GTX-580's with sealed liquid cooler; but I also have three laptops which crunch (CPU only, 60%). I do not have Thunderbolt, just USB2.0 on thee machines.

When I brought on the desktop with GPU's, I went from about 11,000 credits per day to between 150,000-180,000 per day. So, you can see that depending on the money cost, anything that I could do with one or two of the laptops with external GPU could be helpful.

I've found a product that claims to do that:

http://www.newegg.com/Product/Product.aspx?Item=N82E16815158162

I've found nothing on whether it has adequate bandwidth for a reasonable credit level, or whether it is even compatible with GPUGRID workunits at all.

I'm crunching with an ASUS G55 laptop (GEFORCE GTX 660M). Overclocked and all it runs below 80C (CPU is busy crunching WCG, so it also generates heat).

This is what I call efficient cooling.
