    If you plan on taking your laptop with you to class, wireless is definitely preferred
    Less plugging and unplugging of your USB port, so less wear
     
    But if you ask me, I'd personally get a different mouse to bring to class as gaming mouse tends to require more frequent charging and it sucks to run out of battery when you're in class
    Bonus points is that you don't have to take mouse out of your bag every day
     
    I used a wired gaming mouse at home and pack a Logitech M545 mouse in my uni bag
    Though, Logitech's wireless gaming mouse should perform fine if that's what you're concerned about
    I'd personally go both wireless if given the choice to pick my options again

    32gb won't do anything at all, even if streaming and gaming, i've never seen more then about 10gb usage while running a game, even with multiple backround tasks and you only get performance degradation if ram is filled right up to or beyond max capacity.  Even at 8gb (2x4) you rarely see a performance improvement going to 16 at same speeds, only in a few newer titles that use slightly more then 8gb including backround processes (win10, steam,discord, chrome etc in backround) does it make a difference. 

    32gb is for work not for gaming, and by the time games might actually use slightly more then 16gb we'll probably be on DDR5
     
     
    For overclocking the sweet spot is pairing speed of ram with highest speed you can get out of infinity fabric while stable, so if possible ram tweaked to 3733 speed and 1866 FCLK, or if lucky ram at 3800 and 1900 FCLK.  3600 C16 is the sweet spot in regards to buying affordable ram right now, plug and play no tweaking.

    Do you already own the vipers?
    if not see what and if they sell this for in your region, look up "F4-3600C16D-16GVKC"

    That is true, however dual rank is also far more difficult to overclock due to the addition of dual rank tertiary timings that come into play. For someone experienced with overclocking ram, dual rank is almost always a better choice. For someone just starting out, I would recommend sticking to single rank and 1DPC. From there, upgrade to 2DPC, then if you still need capacity, move on to the larger dual rank DIMM's.

    Depends on the timing. Most primary timings have a negligible impact on bandwidth. The biggest timings that impact bandwidth are the tertiary timings. RDRD, unsurprisingly, can improve your read bandwidth if configured properly. The issue is, if you go too loose or too tight on the timing, and it impacts the way your RTL/IO-L offsets are training (This is for Intel, no idea what AMD calls theirs), you will end up losing bandwidth AND increasing your latency. Lower isn't always the best, it just depends on what the IMC will tolerate without breaking training values elsewhere.
     
    The thing to note is that your actual bandwidth can never exceed your peak theoretical bandwidth. For example: DDR4 3600 has a peak theoretical bandwidth of 57,600MB/s in dual channel. No amount of timing adjustments will ever let you exceed that value, however you can improve your bandwidth efficiency to get as close to that value as possible.
     
    The biggest metric for judging relative memory performance is overall Round Trip Latency. It is a culmination of every single timing as well as the frequency of the ram. You want to reduce that value as much as possible while maintaining stability. This will involve a balance of both ideal frequency as well as very tight timings. 
     
    Another way to improve latency is by prolonging the time your ram remains active before a refresh, as well as increasing the speed at which it refreshes. So increasing TREFI to it's highest value (65535) and reducing tRFC as low as you can get it while maintaining stability, it's a free increase in performance assuming you can keep the DIMM's cool with some airflow.
     
    I really need to sit down and work on memory overclocking for Ryzen, I just don't know where to start. I want to make a guide that encompasses all aspects of memory OCing for Ryzen, but their IMC's differ dramatically when comparing Ryzen 1000 series to the current 3000 series.

    well there's your problem..
     
    depending on the budget there's a lot of directions you can go..
    - i'm using what's essentially small business equipment from linksys, with a pricetag to match (the whole setup was just past €500)
    - linksys has some pretty decent gear for the home too
    - beyond that (some of) ASUS's routers are pretty good too.. (i'd have one of those if my power grid didnt keep killing them..)
    - etc.
     
    i kinda personally recommend to stay away from mesh stuff because while it's easier to set up.. it does crowd up the frequency a lot more than i'd deem necessary.

    junzhi2002 reacted to AngryBeaver in Network of 2 wireless routers   
    So what is basically happening is you are taking 2 routers and letting one handled all of the DHCP and firewall activities, while reducing the other to a wired hotspot/switch. You would disable the DHCP server and firewall on the second router. You would not use the wan port, because then your other devices would be on another network segment and communication between those devices and your other devices would require more configuration. When you use the Lan port you are bypassing the Nat function and allowing all of the machines to communicate to each other.
     
    I hope that makes sense. This setup just means you will have the best possible wifi speeds without needing to do a lot of setup outside of a simple Static IP, turning off DHCP, and disabling firewall on the second router. All of which should take you less than 5 minutes from the web console.
     
    Then you just need to setup the wireless networks on both. Make sure they are not using the same SSID (wifi name). Then you will need to setup all your wireless clients so they can connect to both of these wifi networks, then as you move around in your home the wireless devices can switch between these networks depending on signal quality and strength. There are other alternatives, but this one would probably yield the best experience.
     
    Alternatively if you are needing to buy both routers anyways. then if you internal home wiring is decent you could pick up something like a R7200 DST. Which is a wireless router, with a wireless AP that communicates via powerline. So you could potentially get good speeds with that type of setup.
