If you caught our last #PokdeLIVE episode, you would have known that the ASUS TUF Gaming FX505D is pretty upgradeable. Looking at the video probably wasn’t the easiest way to understand how to upgrade your laptop, so we decided to disassemble the ASUS TUF Gaming FX505D again, take a few photos to show you what and how you can upgrade the parts in the affordable gaming laptop.

Taking off the bottom cover

There are a total of 11 screws on the bottom cover, five of which are shorter than the other six. We placed screws beside the holes they fit into, so that you can use this photo as a reference. Just in case you forgot how they go in. Now after removing all the screws, the clips are a bit more challenging to detach. I recommend pulling upwards from the rear corners because there is a lip between the bottom panel and the hinge mechanism. Be gentle though as this is plastic. Carefully slide your finger between the gap and lift it off the body of the ASUS TUF Gaming FX505D once you have disengaged all the clips.

Once it’s all off, you can take a breather and marvel at the beautiful contrast of the bare copper heatpipes against the blue PCB in the ASUS TUF Gaming FX505D. The amount of heatpipes are similar to ASUS’ higher end models, which is probably why we saw nice temperatures when we reviewed the laptop.

What can you upgrade?

Unlike some of the thinner and lighter gaming laptops produced by ASUS, the RAM here are all slotted ones, none of those non-upgradeable soldered RAM here. ASUS threw in DDR4 2666 MHz RAM here, but due to the limitations of the AMD Ryzen mobile processors, they only run at up to 2400 MHz. That’s something to note when getting your new SO-DIMMs: you won’t gain anything from spending more for faster RAM because 2400 MHz is the limit. You can max out the memory support with 32GB DDR4 2400 RAM (16GB x 2) if you want, just so that you can feed Chrome better.

The 2.5″ drive

Two screws hold in the caddy for the 2.5″ drive. ASUS provided us with three screws in the box, allowing you to secure your drive in the caddy. Of course, with a 2.5″ bay, it means that you have the option to pick either fast SATA SSDs, or opt for more storage, but slower HDDs. We have our Phidisk WrathKeeper here which we can slot into the 2.5″ bay. ASUS kept this 2.5″ bay empty, so throwing in a 2.5″ drive won’t need any migration or backup. Just throw in a new drive, and you are set.

The M.2 SSD


What can you upgrade in the ASUS TUF Gaming FX505D? 39

There’s a M.2 PCIe Gen3 x4 slot here in the ASUS TUF Gaming FX505D. Out of the box, there’s a 512GB Intel 660p M.2 PCIe Gen3 x4 NVMe SSD in it. What’s really cool about this is the PCIe Gen3 x4 support, allowing you to upgrade with high performance M.2 PCIe SSDs like the Samsung 970 EVO if you want. Or, a more affordable alternative would be the Phidisk WrathKeeper M.2 PCIe Gen3 x2 NVMe or the Kingston A1000 M.2 PCIe Gen3 x2 NVMe SSDs. Do note that it only supports the common M.2 2280 form factor and not the rarer M.2 2260 or 22110 size. What we don’t know is whether it will support M.2 SATA drives, but those drives aren’t really relevant anymore nowadays.


Now while we are very satisfied with the temperatures we saw when we reviewed the ASUS TUF Gaming FX505D, if one day you want to replace the thermal paste, it’s not going to be that hard. Some laptops have their cooling system under the keyboard, which makes it extremely hard to reach, but this one right here ranks as one of the easier ones to service. Whether you want to repaste for better performance or just perform maintenance and remove the dust in the heatsinks, you can. ASUS did equip it with their anti-dust system, but the heatsinks will still collect dust over time. So yep, kudos to ASUS for ensuring that the ASUS TUF Gaming FX505D is easily maintained. One thing to note though is there are wires running over the left heatsink, so you would need to detach the wires before removing the whole cooling assembly.

One thing that you might realize is that ASUS used copper quite generously here. Most of their previous designs had aluminum heatspreaders over the VRAM and also VRM, but it seems like they decided to go full copper this time around for better heat dissipation.

Fully upgraded

Yeah we are short of a SO-DIMM RAM stick, so we didn’t exactly fully kit out the ASUS TUF Gaming FX505D. But it does now have 1920GB of SSD storage, versus the 512GB that ASUS built in. It’s upgradeable, and you don’t have to jump through hoops to add more RAM, more storage or even service the cooling system.

    Hello.. is it okay if I add a crucial DDR4 8GB soDIMM ram.. will it be compatible?

      The AMD processor is apparently quite finicky when it comes to RAM support… You might have to check on that with your dealer.

    Hey, i just repasted the CPU on mine-, just wanted to mention the wires running over the left heatsink are just the wifi antenna, and easily detachable from the wifi chip below the M.2 SSD.
    Also wanted to note that somehow the factory did not notice that they had stuck a bit of thin plastic on wonky and it was stuck between the CPU and the heat pipes, hence my thermal issues. Nice job ASUS quality control.

    Is the cable for the 2.5 drive provided already? Or we need to buy along with the SATA SSD 3.0?

    One thing I never found an accurate answer to, does it come with 2x4GB RAM, or 1x8GB?

    • Vyncent Chan
      December 19, 2019 at 1:12 pm

      That would depend on your region. In Malaysia we have confirmed that it will be a 1x8GB configuration.

    Note AMD 3550H limitation to 2400 MHz, 2666 is overkill. Make sure second RAM is same speed as the first (and ideally same make), or get a 2 board kit. Max 32 GB.

    • Vyncent Chan
      January 3, 2020 at 4:42 pm

      ASUS actually used 2666 MHz RAM in the TUF Gaming FX505D sample we received, but it was running at 2400 MHz. AMD’s RAM support is indeed slightly more finicky compared to Intel’s… experienced it first hand with the ROG Strix GL702ZC

    Hi Vyncent. Nice summary. Interestingly, the 705DD.308 I got here in Sweden has the opposite configuration – a lousy 256 GB 2.5″ SSD and nothing in the M2 slot. About to put 1TB in SSD to get a quick OS and free up the 2.5″ for something else. Concerned about the Win 10 2TB / 16 TB thing though, to be continued.

    Another thing to mention with this setup – 8GB is really small for the Graphics Card – My 1050 eats 5GB of RAM as well as its own onboard 3GB – which does not leave much. Chrome and 256GB SSD slows it way down. Recommend upgrading to at least 16 GB for any series graphics loads (good gaming etc.)

      yeah the CPU would benefit from dual-channel memory too, but it’s weird that your GPU takes up your system memory as it has its own VRAM. I believe you have some background tasks running?

    Hi Vyncent. Thanks for the info. Just purchased a FX505DV which comes with a 512gb M.2 SSD. looking to add a 2.5″ SSD. is there a size limit? I was planning to add a 2TB Samsung EVO 860.



    • Vyncent Chan
      January 20, 2020 at 9:55 am

      Hi in terms of storage capacity there shouldn’t be a limit. For physical dimensions, it would be best to get a drive that’s 7mm or thinner, so the 860 fits the bill. :)

    Got this laptop last year, the fx505-DT version, in Canada. I made two upgrades to mine.
    Came stock with: 512gb Intel SSD, 8gb RAM, 4gb GTX 1650 GPU + integrated AMD chip, Ryzen 7 3750h CPU.

    8gb of memory goes quick when you mix music and have a trillion Chrome tabs open, and 512 gb of storage didn’t last very long before I ran out of space. I will say, the Intel SSDit came with is very quick.

    For the memory issue I added 8gb ram: Crucial 8gb Single DDR4 2400 MT/s (PC4-19200) off Amazon Canada.
    Very good value chip, integrated perfectly and immediately in dual channel with the stock chip.

    For the storage issue, I added a Samsung 860 EVO 1TB SSD, also works great with this laptop. I had to “enable it” from disk management.. Also great value, SSD has gotten more affordable, I think it’s the better value for sure over HD.

    This laptop is great. It ran any game out of the box, and now it can handle my egregious Chrome tabagerey. The integrated GFX are nice for when I want to game, and have another monitor open in dual display. It’s almost like having two computers. The Ryzen 7 and GTX 1650 work famously together. My first AMD CPU, very happy with it. The only thing, this one runs a bit on the warm side so I was surprised your experience was that the cooling was very good. I suppose even a single hardware change can make a big difference. Anyway, it’s never overheated, or had any issues, just definitely not on the cool side. Feels cool to the touch usually, I have a feeling the sensor isn’t totally accurate but who knows.

    Anyway I highly recommend the laptop, and anyone looking to make similar upgrades, I would recommend both the RAM chip and SSD that I got for a good bang to buck ratio. I think together I paid about $190 CAD for both, though I just saw that the EVO had a huge price jump. Then again if you’re in America it’s probably half the price it is here anyway xD

    Cheers, and ty for the article. I know nothing about cooling, but it’s nice to know I can take a look at that next time I have the willpower to unscrew all those tiny screws.

    Hey, question. My TUF (the DT) has a ryzen 7, and it runs a little warm, around 60ish. CPU heavy games make it push close to 80. Hasn’t caused any issues, but a little warmer than I’d like. Can repasting help with CPU temperatures? Are there better pastes you can buy than something ASUS would use? I really don’t know much about cooling thermal paste.
    Maybe ASUS screwed my paste up lol, considering they sabatoged your heating :p

    • Vyncent Chan
      January 24, 2020 at 3:39 pm

      Well it is worth noting that I was comparing it against recent Intel laptops, which easily run above 90++ when gaming. We have tested a similar TUF Gaming FX505 with an Intel processor and that went a lot hotter, thus my comment about the cooling being effective here.
      With that said, 80-ish is perfectly fine. But if you want to run cooler maybe you can set the fan profile to be a bit more aggressive with the Turbo mode. Repasting should improve thermals a bit, but probably not by much. If you do plan on repasting, we use the MasterGel Maker by Cooler Master all the time here and it is one of the better thermal pastes we have used in terms of thermal conductivity and also endurance.

    So I should get 2x16gb DDR4 2400mhz to get the full potential without being overkill ???
    What’s your recommendation ?

    • Vyncent Chan
      February 8, 2020 at 9:56 pm

      I personally think 2x8GB should be more than enough for anything you want to do on this laptop… The processor here isn’t exactly a beast, so going 32GB really is overkill…

    Hi there, I got my asus TUF fx505DT and I want to upgrade my ram, it already have an 8gb ram but its not enough when I am using Photoshop, there’s always an error occurred.
    So I decided to upgrade it. Is it okay to have an 8gb + 16gb ram? Should it be 2666MHz or 2400MHz?

    • Vyncent Chan
      March 4, 2020 at 3:39 pm

      It is absolutely fine to upgrade the laptop with a 16GB stick. The original stick runs at 2400 MHz although it is specced for 2666 MHz. I would probably go with a 2666 MHz stick just to avoid any incompatibilities.

      You might want to update to the latest BIOS before adding the RAM though, as one of our readers has reported issues with upgrading their TUF FX505D until he updated the BIOS.

    Can you upgrade the CPU in this model? It is heating above the 90 degrees.

    • Vyncent Chan
      March 17, 2020 at 2:59 pm

      The CPU cannot be upgraded, it’s a soldered one

      March 18, 2020 at 3:20 am

      I feel I should mention…. The 3750H processor generally runs hotter than most. Mine typically runs in the 80s for CPU heavy games in turbo mode and idles high around 60. I’ve seen it in the nineties on occasion as well. On silent or preformance it usually idles around 50

      I’ve seen people quoting AMD however that this is completely normal. Generally, if you aren’t experiencing issues, your CPU is fine. Longevity may be an issue, we’ll have to see, but I believe these CPUs are designed to operate at over 100 degrees. It does run a hotter than most, but these newer generation processors are designed to to withstand high temps better. So no you can’t replace them, but I’ve been using this processor almost a year, running it hot and frequent, with zero issues. It’s been great, in fact.

      • Vyncent Chan
        March 18, 2020 at 11:21 am

        Idle temps are a little high but load temps are definitely fine. Also, AMD’s chips are relatively cool… You should see Intel’s recent laptop processors running at around 90C…

    Please could you offer some advice!? I have tried to add a 1TB ssd in the empty 2.5 slot but it doesn’t show up anywhere, even disk management. I plugged it in using a usb adapter and it shows up in the disk management. Unplugged and reinstalled into the 2.5 slot and it’s gone! Am I missing something? Many thanks in advace

    • Vyncent Chan
      April 2, 2020 at 12:04 pm

      Hi, did you connect the SATA cable that comes in the box to the SSD and the motherboard securely?

  • Si
    April 2, 2020 at 3:49 pm

    Hi Vincent, there are no spare cables included in my box unfortunately. There was no HDD in place but the carrier and bit it plugs into were there the same as your pictures above. Do I need an additional cable then, and if so where does it go!? I can’t see it on your pic 6 above! Many thanks

    • Vyncent Chan
      April 2, 2020 at 10:16 pm

      The cable will connect the drive to your motherboard. If there wasn’t a drive there then they would most probably have put the cable in the box separately. Unfortunately we no longer have the laptop with us so I can’t send you images of the cable…
