    Pachuca reacted to mariushm in does anyone know where to get cheap thermal pads   
    You can buy bigger sheets from an electronics distributor and cut the squares and rectangles you need.
     
    Here's a bunch of thermal pads with thickness between 0.039" (0.991mm) and 0.0433" (1.1mm) : DIGIKEY Thermal Pads page (pre-filtered to thickness range and in stock only, sorted by price)
     
    Look at the thermal conductivity, you want high value ... Thermal Grizzly says it's 8-W/mK so look for around 6W/m-K or higher. 5W/m-K will probably also be fine. 
    try not to get conductive pads,
    don't look for the cheapest per unit, also look at square area, you may find a bigger piece cheaper than buying 10 smaller pieces.
     
    For example

    36$ (0.0016 per mm2) 150mm x 150mm x 1.016mm 6W/m-K : https://www.digikey.com/product-detail/en/t-global-technology/H48-6G-150-150-1.0-0/1168-1294-ND/3042123
    30$ (0.0005 per mm2) 288mm x 192mm x 1mm 5W/m-K : https://www.digikey.com/product-detail/en/t-global-technology/TG832-288-192-1/1168-2188-ND/7928340
    8.5$ (0.0008 per mm2) 101.6mm x 101.6mm x 0.991mm  5W/m-K : https://www.digikey.com/product-detail/en/wakefield-vette/PL-1-5-1016/345-1524-ND/6680593
     
    13.2$ (~ 0.0022 per mm2, 242mm x 24 mm) : 1.32$ x 10pcs x  [24.2mm x 24.2mm x 1mm] 6W/m-K : https://www.digikey.com/product-detail/en/t-global-technology/TG6050-24.2-24.2-1/1168-1692-ND/3300350

    Pachuca reacted to colonel_mortis in C++ (premature) optimization   
    In a 64 bit application, a pointer takes up 64 bits = 8 bytes (and on 32 bit, it's 4 bytes). The size of an int varies by platform, but is generally 32 bits = 4 bytes.
     
    Optimising a couple of bytes is very definitely premature optimisation. However, in this case method 1 will be more efficient.
    In terms of memory, method 1 has 4 bytes for x, while method 2 has 8 bytes.
    In terms of speed, method 2 involves a pointer dereference, which is a minimum of one extra instruction (and in the event of a cache miss, it will take several cycles).
     
    For that use case, it's usually a better idea to use preprocessor macros, which are resolved at compile time and have no runtime overhead
    #define CUSTOM_C_DIMENSIONS 10 Then rather than accessing CustomC::x, you would just use CUSTOM_C_DIMENSIONS.

    Pachuca reacted to BobVonBob in C++ (premature) optimization   
    Dereferencing a pointer is when you use the data location the pointer is pointing to
    int* i; *i = 5; //dereference

    They should come with some usually speaking but if not you need to make sure you get ones of the correct thickness for it's application. Some of the best one's would be the thermal grizzly ones but with that they come with a price, I usually recommend the stuff from 3M or what EKWB supplies.

    Pachuca got a reaction from SINCLR in 3200mhz and 3600mhz, what is the difference?   
    there was a good episode from GN about answering this. It depends what chipset your using and if you plan to overclock. Some mobo/cpu don't even support higher than 2133mhz so getting the faster ram won't do you any good because they will actually run at lower speeds if you don't use xmp etc.

    Pachuca reacted to Lurick in recommended ethernet wire cat 5 or cat 6?   
    The flat ones probably have little to no protection whereas the round ones have additional shielding and are better rated. A lot of flat cables that I see are also CCA which is generally pretty bad and much harder to crimp/make your own.
    In terms of performance, Cat5e vs Cat6 for gigabit speeds, there is no difference. Just make sure it's not CCA cable (copper clad aluminum) and you'll be good.

    Here's pics after 2nd Delid attempt. I cleaned the cpu before I could take a pic of how much LM was there, but it looked similar to the IHS. In the 2nd pic I added more LM to both the core and IHS. This actually decreased temps by another 5c, I guess the first application wasn't good enough. I'm now getting 15c decreased temps.

     
    also I tightened the clamp more this time to make sure the glue would really get compressed and not leave additional space

    I would like to use nail polish to prevent anything from leaking and damaging the cpu, do you have any suggestions on what's good to get? I read somewhere that benzene derivatives in nail polish can harm the cpu, but I have no idea which nail polish is good for this. What did you do to prevent damage in case the LM spills inside the IHS?

    Pachuca reacted to Mira Yurizaki in any good 17" gaming laptop backups?   
    You should buy something that expensive. Or at the very least, consider it. Something that expensive will last. When I wanted to buy a backpack for motorcycle riding, I figured I could get buy with a $20 backpack. I don't ride all that much (maybe like 1000-1500 miles per year), but the backpack started wearing out within a year. It lost its shape, the rubberized coating on it flaked off. It also wasn't very comfortable to wear. So I got myself something else. It was more expensive at like $70, but I can already tell it's designed to be much sturdier and it can comfortably fit up against my body rather than hang off my shoulders.
     
    And no, riding a motorcycle really had nothing to do with it. I've had backpacks throughout college that been through a lot but were still in much better shape than the $20 by the time I replaced them. Enough so that I donated the old ones, but the $20 one was the only one I threw away outright.
     
    Also that brand is good (it's the company that makes the real Swiss Army Knife), but I'm also confusing them with SwissGear (which is also good) . If you need other brands to look at, I recommend Samsonite and Thule. I currently use a Thule backpack (it's too small for what you're looking for though), though my motorcycle backpack is an Under Armor one since I need something with a voluminous pocket. Another brand I used to buy was Targus, but they're like midrange.

    Pachuca reacted to SpencerC in Wccftech: Ampere allegedly launching on March 26-29th (GA104)   
    Why would NVIDIA make their xx70 and xx80 cards based on a XX102 chip? Aren't those reserved for the Titan and xx80 Ti lines? Regardless, this is coming from WccfTech, which means that within a margin of error almost everything in that article is false / should be taken with a HUGE grain of salt.

    Pachuca reacted to Joonikko in Panel - Autohotkey-based GUI for common Windows elements   
    During the summer I worked at a small IT shop doing basic installations of computers for clients. Since 99% of the computers went to random places, things such as volume licensing or AD weren't an option for easy installation and setup.
     
    Microsoft kept rearranging the Control Panel & Settings application in every update, so it was pretty infuriating to try to do anything and had to keep searching for basic settings,  so I decided to create a simple program/GUI in Autohotkey. I call it Panel, the missing GUI for Windows.

    Source code and compiled exe's are available in the Github repository

    It's made with Autohotkey and the installation functionality uses the Chocolatey package manager.
     
    Features
    - GUI with buttons to quickly access settings, folders etc. (that do not constantly move or rearrange. Hint hint, Microsoft)
    - Ninite-style GUI for installing applications via Chocolatey
        - To use the installation feature, you need to have Chocolatey installed or install it with clicking the CMD- or PS Install buttons, which will run the command to install Chocolatey.
    - KDE-style alt+drag window moving and resizing. Original script by Jonny from Autohotkey script showcase
     
    Hotkeys
    - Global
        - alt+§ WindowShade
        - alt + left/right mouse button  Move and resize windows
        - ctrl + q Send alt-F4
        - ctrl + h minimize window
    - Windows Explorer
        - F1 up 1 directory
    - Panel
        - F1 cmd.exe
        - F2 Run… -prompt
        - F5 reload Panel
        - F6 reload Panel as admin
        - F7 run WUMT.exe (Windows Update Minitool, needs to be in the same directory as Panel)
        - F8 Run portable CCleaner (needs to be in the same directory)
        - F9 Windows Update
        - F12 Open Folders panel that stays on top of other windows
        - alt + q UAC settings
        - alt + w Control Panel
        - alt + d Task Manager
        - alt + F1 Turn display off



     
    I didn't originally make it to be published anywhere, but since a lot of other people are also having the same frustrations with Windows, I decided to release it.
    Any comments, suggestions or improvement ideas?

    use DDU to uninstall the driver completely from safemode then reinstall the drivers.
     
    edit: You probably have a bad update and need to reinstall the drivers. For some reason windows has a hard time uninstalling nvidia drivers correctly. I recommend using the DDU software provided in the link above.

    Actually I don't know. But the SATA bus also uses some Gen2 PCIe lanes and mining cards can work off a single Gen2 lane so I wouldn't worry about it

    Pachuca reacted to Jurrunio in Coffee lake i7 8700k vs skylake i7 7800x   
    depends on how good you are in tuning the CPU and what kind of work you throw at it. 8700k wins when it comes to simple overclocking, i.e. increasing core clock multiplier and BCLK. To squeeze everything the 7800x has to offer out means increasing the AVX frequency as well and do AVX heavy task, in which it smashes the 8700k.
     
    As for price, 7800x itself is cheaper than 8700k, but the mobo is so much more expensive it's eventually more expensive than 8700k. Not to mention X299 chips rely significantly more on RAM frequency because of the mesh architecture, which is different to the ring bus used by the 8700k and more similar to AMD's infinity fabric in comparison
