Hey! :) Does my CPU fit in my motherboard?

So hey i wanted to upgrade my cpu after upgrading my GPU and i wanted to upgrade from Intel pentium g4400 to INTEL Core i3-8100 and my motherboard is PRIME B250M-K
and i just wanted to know if it will work on my motherboard :) thanks for the reply :)

  1. Ur cpu choice wont work since it only supports 6th and 7th gen cpus. Try a something like Intel Core i3 7100. U might need a bios update as well.
  2. Fit yes. Work no. The 8th gen cpus currently only work on the Z370 boards. Your B250 only supports 6th and 7th gen cpus.
  3. No the g4400 is 7th gen, the 8100 is 8th gen. Even tho both are socket 1151, theyre not compatible with each other

    If you want a Coffee Lake CPU, you'll have to replace the mobo with a Coffee Lake mobo

    Please don't use txt speak, this is a forum not a SMS. Some shorten is ok but but u an ur? Come on man.
  5. Grab the i5-7500 as the performance should be pretty close to that 8100. This way you won't need to worry about having to get a new motherboard or having to reinstall the OS.

    Well would something like Intel Core i3-7100 work? or I3-6100?

    Sorry its too expensive for me the i3-8100 was the most i could afford now. how about I3-7100 or I3-6100 would those work just fine?

    well if i get that i3-7100 why would i need BIOs update and is it 100% necessary?

    They would but your better off with the Pentium equivalent as there both dual cores with hyperthreading, look at the G4560 or better. Or just save up for the 7500.

    well i could save up for the i5-7500. thanks and another question is i3-7100 even worth the 110 euros (i live in europ so i have euros) like is the preformance upgrade worth the 110 euros because i think g4400 and i3-7100 dont have much difference and the 110 euros are probably not worth it so i could save for the i5
  11. No, save up for an actual quad core as it will be a massive upgrade over that G4400.

    oh and another thing does i5-7500 and i5-7400 how much difference? they have 20 euro difference in price tho

    Here is a list of processors supported by your motherboard along withy the requisite bios level.
    https://www.asus.com/us/Motherboards/PRIME-B250M-K/HelpDesk_CPU/
    CPU-Z will tell you what your bios is.
    You can also see the bios level in the bios initial screen.

    If you bought the motherboard a long time ago and have not since updated the bios, you will likely need to do so to support a I3-7100.

  15. The 7400 is decent but I figure the 7500 for the slightly higher speed but either of them would be a good upgrade.

    is 4 cores way better than 2 cores? sorry im just new to all this computer world

    Ok thanks. i think ill go with i5-7400 because i REALLY can't go any higher in the price right now and i need to buy a new monitor too so ill need some money there too but any ways thank you all for your tame :) TY
  19. Windows apps see only threads.
    From that point of view, a I5 7400@ 3.0 has a passmark rating of 7415 when all 4 threads/cores are fully utilized.
    It has a single thread rating of 1959. Single thread performance is important for games. Few games can effectively use more than 2-3 threads.

    A processor like the I3-7100 @3.9 has only two cores, but 4 threads.
    The extra threads make use of unused parts of the main core to dispatch a second thread.
    Of necessity, the second thread will be less capable.
    It has a passmark rating of 5838 but a better single thread rating of 2232.
    If your main use is for multithreaded apps, then full cores are preferred. Ryzen is very good for this.
    But for gaming, faster threads are preferred.
    An exception might be multiplayer games where many threads is more important.

    well which would you personally use for games like fortnite or GTA 5 i5-7400 or i3-7100?
  21. 7400.

    The motherboard came out with the sixth gen CPUs. If you want to use a 7th gen CPU they usually require a bios update. The support page for your motherboard says the 3 7100 has been supported since bios 0301, so if you already have at least that one if not a newer one then you're good to go.

    edit: haha, this thread moved fast, I'd also recommend an i5, you want a quad core if possible and that means an i5 in the 7xxx series

    well does the i5-7400 work with BIOs update (if needed)

    A good question that I can not answer well.
    I personally can buy what I want, so my upgrade would be stronger.
    Either choice gets you from two threads to 4 so that is good for anything.
    As I understand it, GTA£589.95 is not a well optimized game that is cpu dependent.
    I suspect that the better single thread speeds of the i3-7100 might do better for you.
    I suggest you try to find good benchmark reviews of the i3-7100 vs. i5-7400 for GTAV

    i just looked it up and the FPS is very minimal between the i3 and i5 CPUs so ill think ill go for i5

    and one more thing i looked at an i5 CPU and it has 2.4 GHz and my pentium g4400 (which i have right now) has 3.3 GHz will something change in the speed or not so much?
  29. There are many I5 processors.
    Which one are you referencing?

    7th gen processors are a bit different from 6th gen(look at the first digit of the name) and may require a bios update

    Do you have a link to where you found differences?

    well i was thinking about i5-7400 or i5-7500 how about those? i know they fint and if i need i have the link to BIOs upgrade than
