  1. Hi all, I'm living in Canada and I have a Shaw BlueCurve plan that comes with the modem/router. Browsing the internet is inconsistent and playing game is quite hard. Counter-strike is lagging a lot if a few people start using the internet at the same time. The connection is awesome right next to it (600 Mbps) but in the office it drops to ~15Mbps in a smartphone. Plus, the internet provider installed the cable right on the corner, making the placement of the router a little more challenging. Currently, it is positioned right next to the cable, but I intend on moving it more towards the center of the house. In addition, I wanted to buy a dedicated router which should solve my problem. I attached a quick draft of my house. I am on a budget, so I would like to spend less than CAD 150. If someone convince me, I might think of going up to CAD 200. This is my list so far. Any suggestions? #1 - Tp-Link AC2600 (Archer A10) - Amazon link #2 - Netgear R6400-100CNS (AC1750) - Amazon link
  2. Thank you very much for all the info. My plan is to buy two 16 GB from Crucial, but my budget might not allow it for now. I did some little research and found that mixing 8 GB with 16 GB is not ideal but doable. Do you have any personal experience with mixing and matching RAMs? My laptop came with one stick of 8 GB at 2666 Mhz, but I read that the motherboard maximum is 2400 MHz. Since there is already a bottleneck I might not lose much from mixing the RAM.
  3. I see, it makes sense. A data set generally have multiple files with 500 MB to 3 GB each, while the total averages around 8-10 GB. However, the useful information used by the program is only a fraction of the total size. The maximum supported by the motherboard is 32 GB. In my case will 2400 vs 3200 MHz make a difference? Thank you!
  4. I took pictures of the task manager because the laptop is way too slow for a screenshot. I took one right after opening task manager(1) and another one after it "stabilized"(2). Also, I copied this from the software's website. Hardware requirements Intel Pentium III/800 MHz or higher (or compatible) although one should probably not go below a dual core processor. 2 GB RAM minimum. 2 GB RAM per thread that is executed in parallel is required. There is no upper limit on the number of cores. Whatever you can fit into a shared memory machine will work as long as the disk performance scales up with it. Does it mean that if I use 7 cores than I need 14 GB of RAM? Thank you very much for your help!!
  5. Hi everyone, I use a program to analyze some data, but the run time is around 1 or 2 days to finish. I wanted to know what is my current bottleneck and maybe upgrade it to shorten the run time. The software is MaxQuant. In summary, it is used to identify proteins by matching an experimental feature to a database, this way it gives the proteins in that sample. I heard that a SSD is very important as it needs to write a lot of stuff on the drive. My computer is a Lenovo E590. Intel 8th i5, 8 GB of RAM, and M.2 NVMe storage. I opened Task Manager and the RAM usage is at 99%, but is it that simple? I know that laptops generally cut CPU power to save battery, can it also be the case? Also, how do I assess my SSD to check if it is powerful enough?
  6. Hi guys, I am planning to buy a laptop for school with good specs so it lasts for a long time. I have a particular interest in Dell Inspiron 15 5584 that comes with a Qualcomm DW1810, does not have bluetooth 5.0, and does not seem quite fast. I am thinking about replacing it with the Intel 9560 and it seems compatible by their website (https://www.dell.com/support/manuals/ca/en/cabsdt1/inspiron-15-5584-laptop/inspiron-5584-setup-and-specifications/communications?guid=guid-13c30394-f35f-4f23-8d8b-8f8f6ac390e8&lang=en-us). Do you guys think it will work? My main concern is the number of antennas. I don't know how many it has, but it seems that I would be switching from 1x1 to 2x2. The other option is to buy the Lenovo E590. Best, Luiz
  7. I don’t have many options. I want something portable, no onboard Ram, capable of Nvme, Bluetooth 5.0 and up to 1000 CAD. Just the fact of not wanting onboard ram already cut my options to half. Why would you say GF63 is mediocre?
  8. Today I went to a Memory Express store and got my hands on both MSI gf63 and Lenovo E590. I have to say that now I am more inclined to buy the E590. The MSI has a plastic chassi and the keyboard is not that great. The Lenovo doesn’t have a dGPU and is a bit heavier, but seems stronger and have a numpad and (apparently) a better keyboard. What are your thoughts?
  9. Thank you. I will take that into consideration, but I am really worried about the keyboard. I know that for this price I will have to make little sacrifices... It is hard to say because I've never used a laptop on the go, mine is always connected to the outlet, so I would guess 4-5 hours. I'd prefer 15.6 as long as it is light (4 to 5 lbs); otherwise, it is ok to be a 14".
  10. Thank you for your help. I was not looking for gaming computers but your suggestions about MSI computers was really useful. I don't need dGPU. It would be good to have one but I don't know how much they can impact the battery life. Max weight I would say around 4.5 lbs (2 kg). It does need to last an entire day, but a good amount of battery would also be useful Right now I am in between Acer Aspire5 A515 and the MSI GF63. I am not so sure if the Acer handles Nmve quite well and I heard the screen is not that good, but the keyboard has a numpad which is useful. On the other hand, I heard the MSI keyboard is kind of crappy. Newegg prices: Aspire5 A515-52G-57TT (refurbished) = $709 Aspire5 A515-54-53Z2 = $849 MSI GF63 = $969 What do you guys think?
  11. Hi, I am a PhD student living in Calgary(CA) and looking to buy a new laptop. I work in a lab that does a lot of proteomics analysis using software like MaxQuant and ProteomeDiscoverer. These software's depend on the processing power and writing speed to finish the analysis faster. Therefore, I wanted something until 1.000 CAD, i5 8th gen, 8 GB RAM, 256 GB Nvme, portable and as upgradable as possible. I know I might be nitpicking but I didn't want onboard (soldered) RAM and if possible Bluetooth 5.0 (not so sure about this last one). What are your thoughts? So far I found the ThinkPad E590, but it is 15.6". Thank you in advance!
