Things to look at before buying a motherboard

Whatsoever may be the brand of your CPU processor, a compatible motherboard is an absolutely important aspect to look at, below are some of the most important and basic things, that need to be taken under consideration before choosing or buying a new motherboard: 

  1. Form Factor: Initially you need to look at the form factor of the motherboard you are going to purchase. ATX motherboards can be a good preference as they have an additional property of expansion slots which is a useful commodity. 
  1. Processor socket: After the form factor, the second thing that you need to consider is the Processor Sockets, at present time there are only 3 types of sockets LGA, PGA, and BGA. Different  Brands use different sockets as the AMD uses PGA, intel uses LGA. The BGA sockets aren’t well-liked by people as they are permanently bonded with the motherboard. So, before buying a processor, you need to look at the socket of your motherboard. 
  1. RAM: The third thing on our consideration list is the RAM, you might have heard of someone saying that the more RAM, the more is the speed of your system, you heard it right. By the way, the motherboard you gonna buy will tell you the amount of RAM it can support, well the advised memory your motherboard can support must be at least 64 GB. 
  1. PCI slots: The PCI slot works as a connection port which is located on the motherboard. These ports have been a standard part of the motherboard for a very long as they help in expanding the cards and memory. If you are a gaming-centric person and want you’d absolutely require a PCI-e x 16 slots for multiple connection purposes. There are two major types of PCI slots one is the standard one and the other is PCI-express slots for sound cards, wifi ports, etc. 
  1. SATA:  This is the most essential consideration to look at while buying a motherboard, the uses of a SATA port are highly worthy as they allow you to connect an optical drive and storage drive i.e, SSD and HDD. The second most important aspect in this is that you need to make sure that your motherboard offers at least SATA 6 Gigabyte standards, which is the SATA 3.0.  

There are also some additional points included in our list especially choosing a motherboard for a high-end processor like the i9 9900k. 

  • Processor & socket for the i9 9900k: currently there are 2-types of chipsets available in the market, that are powerful & capable enough to go hand in hand with the i9 9900k processor- these are the Z370 & Z390. although it is clear that the higher the number, the more is the capacity, that why the Z390 is a better and more reliable option. 

If we talk about the socket, we have discussed earlier that the intel makes use of the LGA type sockets, but to be more precise in terms of the i9 9900k, you would need an LGA1151 socket to install you 9900k in the motherboard. 

  • Overclocking capabilities: This is the most underserved point, many people don’t even check out this factor before buying a new motherboard.

Especially, it must be checked out by the gaming enthusiasts, you must know that is your motherboard really capable to go the extent of your gaming madness.

The overclocking capabilities of a MOBO come from different factors:

  1. VRM of the MOBO: this basically helps in converting regular voltage & AC to consumable voltage or DC for the usage of CPU. 
  1. Number of heatsinks: these are necessary for maintaining the cool temperature of the RAM, processor, M.2 SSD’s & VRM and preventing any burnout.
  1. Other factors include- simple BIOS function, automated propellers, and boosting software which comes different in different brands of motherboards.
