Scan 3XS Carbon Extreme 17″ Gaming Laptop (Clevo P775DM3-G)

Please read this forum thread before you consider purchasing a laptop from Scan 3XS http://forum.notebookreview.com/threads/3xs-carbon-extreme-p775dm3-from-scan-uk.802451

I recently purchased a Scan 3XS Carbon Extreme to replace the previously owned PC Specialist Octane II, as after many issues PC Specialist eventually took the Octane II back and offered a full refund.



Scan 3XS LG17 Carbon Extreme

Chassis & Display: 17.3″ 4K G-sync 60Hz (3840 × 2160)
Processor (CPU): Intel® Core™i7 Quad Core Processor i7-7700k (4.2GHz) 8MB Cache
Memory (RAM): 32GB Corsair Vengeance 2400MHz SODIMM DDR4 (2 x 16GB)
Graphics Card: NVIDIA® GeForce GTX 1080 DESKTOP – 8.0GB DDR5, G-SYNC – VR Ready
Thermal Paste: ARCTIC MX-4 EXTREME
Wireless: INTEL® AC-8260 M.2 (867Mbps, 802.11AC)

I will be installing Windows 10 Pro on the 512GB SAMSUNG 950 Pro M.2 which I kept from Octane, together with a Samsung  1TB 850 EVO and a 2TB Samsung 5400RPM HDD.


Unfortunately, the Clevo P775DM3-G suffers with exactly the same overheating issues present on the P775DM1-G. Well, it was actually quite a bit worse due to the increased processor performance and the extra heat this generates.

So much for the supposedly improved heatsink design – shame on you, Clevo!

Before I returned the laptop to Scan I had renamed it the Scan 3XS Carbon Extremely Hot. I am hoping I just got a bad example of an Intel i7-7700K (rumours are there are plenty of them about!) and that the replacement brings 100% load temperatures down to a more acceptable level.

The first report from Scan’s engineer was encouraging, a replacement 7700K CPU seemed to bring the temperatures down – so it looked like I had originally got a potato, a very hot potato! However, it was then discovered that the charger (PSU) was supplying the incorrect voltage, so a new one was sourced.
Next, it was decided to replace the entire chassis,  just in case the power anomaly had caused any damage. Following this Scan went a bit quiet. It was then reported that they could not get the temperatures below 90 celsius when both the GPU and CPU were running at 100%.
The laptop was returned within 14 days, so I hope to be receiving a full refund fairly soon.

Combining the power of an Intel i7-7700K and Nvidia GTX1080 in a laptop with an inadequate cooling solution means you will have to make compromises. Don’t expect to be able to use it out-of-the-box for any program which will stress the GPU and CPU together, without temperatures getting ridiculously high. You will need to undervolt the CPU, you will need to disable the 4.5GHz turbo boost feature and limit the CPU to run at a maximum of 4.2GHz, you will probably start looking into how to delid a Kaby Lake CPU and you will definitely need to invest in a decent laptop cooler or just ignore the temperatures (which I think Scan does when they do their post-build QC and testing).

I am now looking into obtaining a Clevo P870KM1-G with a single GTX1080 and a delidded i7-7700K, apparently, the cooling solution on the P870’s is a lot better than on the P775’s. So I am hoping to have a review on here soon!

Then Nvidia announced the GTX980ti and AMD release the Ryzen. I will now be looking at building a mini-ITX to directly hook up to our 4K TV, instead of using the Nvidia Shield TV to harness the power of the laptop to stream to it using Gamestream. I should still have some change from the budgeted cost of the P870KM1-G to buy a cheap or refurbished laptop with a 1060 or 1070 in it. The 1070 will still be more powerful than the GTX980 in the P775DM1-G that went back a while ago!

Well, after a lot of what should be unnecessary nagging, Scan have eventually got round to ‘processing’ the refund. They have really dragged this out.
If you do want a good gaming machine with a GTX1080 then the P775DM3-G is still a good one but it really is pointless putting the Intel I7-7700K in there too. Apparently, the i7-7700 runs cooler or perhaps try the i5. I did try a 6700K in the chassis and that will run OK with a good repaste and a fair amount of tweaking but don’t expect to do any overclocking. If you are after something that will do rendering or anything else which requires grunt from the CPU and GPU at the same time, then please look elsewhere for your desktop replacement machine.
