    I’ve recently purchased this machine in Hungary (FX505DU) and love it for most bits. For the price the performance is very impressive, and I got the free mouse, pad, headphones and backpack as well.

    On the negative side though:
    - Drivers on the ASUS portal are rubbish: AMD scripted install fails, ROG Armoury fails to recognize the video card, AURA stuck in rainbow mode, and other minor issues requiring extensive workarounds to fix them
    - I experience sudden irrational frame drops in games. From stable 70-80 the frames drop to 10-15 for 5 seconds then it’s restored to 70-80 again. It’s very ad hoc and varies from game to game, some examples:

    Fallout 4: 90 frame average, frame drop occurs once per hour
    Battlefield V: 70 frame average, frame drop occurred 3 times in 7 hours
    Assassins Creed Origins: 60 frame average, frame drop occurred 2 times in 10 hours
    Ryse Son of Rome: frame drop from 80 to 15 every 2 minute (restored after 5 seconds)
    Crysis 3: frame drop from 80 to 15 every minute (restored after 5 seconds)
    Doom: stable 60 frame, no drops in 8 hours
    Apex Legends: stable 70 frame, drops in 10 hours

    It’s a noticeable with the older titles, but I sometimes experience it with recent ones as well, thus I’d like to get to the bottom of the problem. All drivers are up to date, I experience the problem both in balanced and turbo mode as well; as I get consistent 70-80 frames the problem shouldn't originate from in-game settings.

    Anyone else experiencing the same?

    hey man thanks for your review, could you please give some info about the following:
    - any backlight bleeding on the screen ?
    - in idle fans are annoying ?
    - battery life ?

    I am very interested in buying this model too..

    Back light is minimal, the 120 Hz refresh rate is really good, every movement is silk smooth. In idle the fans are very silent, keeping the noise to minimal, though opening Chrome will have them immediately up to speed. While gaming the fans are loud, but honestly I don't care as I'm using headphones. Battery life is not so great, 90 mins reliably, but again this is not a problem for me as I use them plugged in.

    The thing is as this being a new ASUS model, I got a 2 month buyers guarantee as part of the promotion here in Hungary, where I can return it and get my price back. Yesterday evening I decided to go forward with it. I've been testing it for two weeks now, and the frame drops I mentioned earlier should not be happening. I've read the same problem come up for other people as well, it's the thermal throttling on the AMD processor most likely originating from the poor quality thermal paste. I could go forward with repairs under guarantee but it's simply unacceptable that a 1000 USD laptop behaves like this after two weeks. Crysis 3 is the perfect game for testing this, it runs amazing for 2 minutes, the frames drop to 5 for a couple of seconds, it goes back up to 80, then the process repeats. It's a 6 year old game...

    On paper the specs should be more than enough to handle anything with high settings, the poor assembly however prevents this. If you decide to go forward with the purchase make sure the dealership allows returns under guarantee and test the machine extensively. I hope you'll get well functioning model. I'll have the machine for 1-2 days before returning it, I can test a couple other things if you'd like.

    I have this laptop and it is true you can have AMD freesync active with the Nvidia GPU.

    Its really nice and at the price point, 120 Hz + adaptive sync is unheard of. Its really hard to go from my 9900k/2080ti 165Hz G-Sync desktop setup but this laptop does a great job in comparison.

    I cant stand most 60Hz non Gsync/adaptive sync laptops.

    Thermals are great, I got about a time spy GPU score of nearly 6000, which is equivalent to most stock desktop GTX 1070. You can get the 1660 Ti up to about 2000 mhz core roughly. I did OC scanner and it gave +147 Mhz result. Mine had Samsung VRAM and I did OC it to +400 mhz in afterburner I think. I did not push the limits on the core or memory yet.

    https://www.3dmark.com/spy/7482400

    The CPU scores almost the same as a Ryzen 5 1400 or a little more than a i5-6600k. So certainly it will be fine for gaming. You should be able to take advantage of the 120 Hz screen in most games. Intel would be about 10 FPS better though in most cases due to the the better IPC, but then you get all the throttling and undervolting that comes with a 6 core laptop chip so its a wash. It can do 60+ FPS maxed on all but a handful of games (like AC odyssey, poorly optimized). A lot of games like Rainbow six siege will easily run 100+ FPS maxed out and youll be able to use that sweet 120 Hz screen to its potential.

    My only real complaint is the fact that the keyboard seems to be stuck in rainbow mode and nothing I do fixes it. Does anyone here have a fix, or even seen it EVER work correctly (changing lighting modes)?

    Its not the worst thing in the world since I got Freesync so I can overlook it, but still it should be mentioned to prospective buyers.

    For about $1000-$1100 its a great value if you consider the Freesync support.

    So I figured out how to fix the keyboard back-lighting situation.

    The entire "asus aura sync" area of the "Armoury" app does not work.

    Rather, you must click the xbox/gamepad controller icon in the armory app and then click "SYSTEM" and then click the "Lighting" tab.

    You will then find a much more basic interface with 4 options "Static, Breathing, Strobing and Color Cycle". You will be able to set the color here as well for the "Static" option.

    Now you can do what you want with the keyboard and make custom colors or set it to static.

    Much thanks for the review. Very helpful. I just picked up one while in China. It has 8gb ram, and a 512 gb nvme. No hdd. Where would you advise getting the drivers for AMD? Should I get them from the manufacturer or the AMD website? I'm worried about the driver stability in this machine


    I also wanted to ask if it would be OK to upgrade the RAM to two sticks of ADATA 2666 mhz with cl 19 timings. I am going to take out the stick already in it.

    Go to AMD's website and chose the right options to download the correct driver.

    It doesn't matter what RAM you choose you will not be able to run faster than 2400Mhz.

    Much thanks for the reply. The RAM is SkHynix 2666mhz cl17 timing. As you said, it runs at 2400 MHz.

    My question is , how much difference due the RAM timing make?

    I bought a 16 GB adata kit (2 x 8) at cl19. Should I use that or try to find another stick of ram at cl17?

    Lower is better, but with the RAM running at 2400 Mhz it may run at CL17 automatically. You can use HWinfo64 to see what timings the ram support at what speeds.

    So at 2666 it might be cl19 but at 2400 mhz might be cl17. The ram is already running pretty slow, I would not worry about the difference honestly.

    On something like my 9900k rig I would care.

    Hey! I had a gaming session with the laptop attached to my TV, and played Arkham Knight, and then I noticed the same framerate drops as you. The youtube reviewers OwnOrDisown and JarrodTech reviewed these machines and both did not notice any throttling. Then in Afterburner I saw that the CPU had hit 98 degrees.

    Was anyone able to fix this issue with a repaste or will we have to use throttlestop to undervolt or underclock the thing?
