    Can I install a Linux server distro over a LAN and have SSH work immediately? I'm upgrading to Ryzen and will still have my old Intel machine and would like to use it for something, but I won't have any graphics devices capable of pushing out an image. It running headless would be totally fine, but I need a way to actually get the distro on there.
    Does it have any graphics capabilities at all? Or is the onboard just broken? Some motherboards won't finish POST without a graphics device. There is also the "stick in a fanless GeForce 210 for $30 option" which would be good enough.

    You can PXE boot a netinstaller, but they are usually still interactive, so you will need to look into the documentation of your distro of choice to figure out how to do an unattended installation.

    So recently I restarted my computer and noticed that my total possible committed memory was at a significantly smaller number than usual (64)

    I'm wondering if thats bad, cause it seems bad.

    Did you recently reduce the size of your page file to 10gb? Total Committed Memory is just RAM + page file size as far as I know

    How good is lastpass as an extension? I've been hearing about it a bunch the past few days and I'm thinking of using it though naturally I'm hesitant to let something manage all my shit. Though admittedly it'd probably be better at it than I am

    Committed Memory isn't just the page file, it's basically pre-allocated memory for processes to use (which includes the page file). Basically, if you opened up a bunch of Chrome tabs, you'd see your committed Memory go up, but if you close all but one tab, Chrome might not deallocate that memory until every single Chrome tabbis closed (AKA Chrome completely closed).

    Look at the Processes tab to see what apps are committing so much much memory for themselves and you'll have your culprit.

    LastPass was extremely good back when I used it.
    Here's a rundown on why I think it's secure:

    The Problem

    Since the early UNIX days usernames and passwords have been used to provide security
    Assuming a system is secure and password based then the one vulnerability is guessing a password
    Passwords need to be 'gibberish' and long
    E.g. 'a' is not a good password as it is easy to guess with a dictionary or brute force attack
    'aa' is still not a good password as there are only 26^2 (676) possible 2 letter passwords which can easily be tried in a short amount of time with a brute force attack
    The longer your password is the stronger it is
    a-z, A-Z, 0-9 and +,- gives us 64 possible characters to use in a password and each character give us 6 bits of password strength as 64 is the same as 2^6
    As you add 1 more character to the password each time you get 64 TIMES (x) more strength


    The Solution

    So the problem is you want a long, gibberish password but you dont want to use the same one all the time
    This means you need many long, gibberish passwords that are hard to remember
    What you want is a way to securely manage these passwords and this is what LastPass provides
    It has plugins for many browsers to make it easy to use
    It also works on many mobile devices
    It also can generate bookmarklets which work in any browser
    LastPass can also automatically fill in forms for you and it has a secure vault where you can store notes


    Is LastPass Secure ?

    All the encryption is done locally on your own computer
    No one but you ever gets the key to decrypt your data and the creators have gone to great lengths to ensure this
    When you log in your email address and password are joined together although your email address is sanitized slightly by being converted to lower case and having whitespace removed
    A hash is then taken of this string using SHA 256
    This is now your cryptographic key that your system uses to encrypt and decrypt your data
    All the data held by LastPass is encrypted
    To identify yourself to LastPass they add your password to the previous hash they obtained by hashing your password and email address and then hash this string
    This hash is your unique ID
    Then you send your unique ID and username to LastPass to identify you and since this contains your password hashed into it twice, no one can produce this key but you
    So LastPass never gets your cryptographic key
    They never even save your unique ID on their servers
    Instead when you create your account they create a unique 256 bit token to save with your account
    Then when you login they take your unique ID add it to the unique 256 bit token and hash it then this is used to find your data
    LastPass also frequently backs up their database


    This is great but what if LastPass goes away ?

    They have a stand alone executable called 'LastPass Pocket' which is a personal database decrypter
    You can export your database in encrypted form and use this program to decrypt the data
    You can export your database in plain text into a CSV file
    Plugins also keep a local copy of this data, and all plugins can export your data

    LastPass' additional comments here:

    You don't need Pocket as the extensions for IE, Firefox, Chrome, Safari and every mobile application keep an up to date copy locally which you always have access to even offline
    You can export your data back into IE or Firefox with the plugins
    http://wiki.twit.tv/wiki/Security_Now_256

    This all means that LastPass physically cannot access your encryption key. If their servers get compromised (which, they have, and they were transparent about it each time), all the hackers get is your encrypted databases, which they still cannot open without the encryption key. LastPass cannot leak your encryption key because they never actually get your encryption key. (This means that if you lose your encryption key, LastPass will just say "Sorry, but we can't help you. We have no way to open these files.")

    HOWEVER, they recently got bought out by LogMeIn (A couple of years ago). I'm not sure I trust these new owners to keep this tech up to the same standards. There is nothing stopping them from changing their system up without notice. They would be under insane fire by the IT world if they did, so they probably won't, but it could happen. So as a precaution, I switched over to KeePassXC on my Google Drive with a password and keyfile solution. This solution is very close to LastPass in usability and still very secure.

    Hope this helps.

    Its not a problem of programs committing memory and not releasing it its more a problem of my computer saying it can only commit up to 22 gigs, at least thats what I gather from the memory screen.

    If you don't own the door your key can never be secure. All "they" have to do is change the lock in order to copy your key.

    That's exactly what I said. As it stands, it is secure, but they can change it at any moment. This is why I instead use KeePassXC.

    You'll probably have to re-activate Windows.
    Since it's the same chipset & CPU OEM you shouldn't have any driver issues.

    I mean W10 in general doesn't have much issue hopping between chipsets.

    Will it be a problem if I got that free Win10 update and didn't note down any authentication? I still have my Win7 disk and stuff if things go south.

    If I get about 200 errors after 1 pass on memtest86+, but the PC somewhat works stable under normal use, how fast should I replace the RAM?

    Currently short on money and most I do is browsing the web or playing some games, nothing where I could loose important stuff.

    Buy a small air compressor, you'll get more bang for your buck.

    Also be careful about condensation coming out.

    Enough hostility, your initial sarcastic post was a little too hostile and I think you know that. I'm just asking for a better method for cleaning out my PC, I'm not asking to be the butt of a sarcastic joke.

    You're fine, just make sure it doesn't push too much pressure out (if it's a good compressor you can change the PSI)

    As it stands, your encryption key is not sent to their servers. This is true. What I said was that (especially under under new management), without warning, they could change their system in such a way that they COULD retrieve your encryption key or otherwise compromise your security. I made a clear warning that because this is a third party they may change their system up at any moment, and because of that I use KeePassXC.

    I did not lie, misrepresent, or hide any facts about LastPass. I said that AS IT STANDS NOW it is secure and usable, but THAT FACT COULD CHANGE SO BE CAREFUL.

    Stop saying I didn't say things when I clearly did.

    Edited:

    What benchmarks should I run before and after a CPU upgrade to get an idea for what performance I gained? So far I did a couple of 3DMARK runs to test gaming performance (not expecting too many miracles there.) What should I throw on there to test pure CPU performance for both single and multicore? I take it Prime95 is on that list.

    Did some more testing with memtest86+ and found out only one RAM module is broken apparently, the other one had 2 passes without any errors while the broken one didn't even last 1min or so until the first error appeared.

    Hm, I have to ask my brother if he still got the bill from the shop where he bought it, but I doubt that. Though I read that G.Skill doesn't need any bills...

    Guess I'll setup my Raspberry Pi 3 in the meantime once again.

    Edit: Upon closer inspection I saw that on the broken module there's a scratch on one of the pins, so RMA is out of question I guess. FML

    That doesn't look like it's bad enough to cause it to stop making proper contact. You could probably still RMA.

    If that pin really is it, you could probably fix it yourself.

    Eh, I've successfully RMA'd damaged RAM. GSkill will rarely ask for a bill, but it's possible.
