Do motherboards have a max gb amount

I am just wondering if a computer has a maximum amount of memory it is allowed to use.
Any replies would be helpful thank you. :)
 
Indirectly, yes. Every mobo has a list of RAM modules it will support in its slots. Every type of RAM module is available only in certain sizes, up to a max. So if you work through what RAM you can use and what is the max size module you can buy for each type the mobo can use, you'll figure out the max module size that fits. This times the number of RAM slots available on your mobo is its limit.

For example, I just looked at one advanced mobo on Newegg and it says it can use 240-pin DDR3 RAM and has 4 slots. That largest 240-pin DDR3 RAM modules I see are 8 GB, so this board can use up to 32 GB of RAM. In fact, the Newegg details for the board actually tells you that max RAM as part of the specs listed.

Be aware that, in any RAM type, the largest modules are always the most expensive. However, on a per-GB basis, they may be the less expensive option. So if you can't afford to buy four 8GB modules, 2 of them (16 GB total) may be cheaper than 4 modules of 4GB each.

Also pay particular attention to how many modules should be installed in a group. For example, some is best used in sets of 2, some in sets of 3.

Now, I answered on the assumption that you mean RAM memory, and not hard drive storage space. But you posted this in the Hard Drive forum, so maybe I'm wrong. The maximum size of hard drive commonly used in Windows systems is 2 TB. But, using a slightly different way of setting it up, you can use larger, and there are some 3 TB units on the market now. Each mobo has a limited number of ports available to connect hard drives to - commonly 4 or 6, and sometimes 8 SATA ports. Many mobos now do NOT have any additional IDE ports on them (an older type of drive), but some do. Reserve one or two of these to use for connecting an optical drive (DVD or CD or Blue-Ray); the free ones, times the size of hard drive you buy, is the limit.

Well, not really. That gives you the limit of what can be connected and controlled by the hard drive controllers built into the mobo itself. Beyond the you can add a hard drive controller card in a PCIe slot that might have 2 or 4 ports on it. And larger systems may use an external cabinet with its own power supply and HDD controller system to handle several HDD units, often in more advanced RAID array systems. These can get very complex and expensive, but they can hold huge amounts of data.

IF your question is about maximum hard drive storage space, you also REALLY should give some thought into how you will provide backup of the hard drives, no matter how large or how many you decide to use. Hard drives do fail and users do lose data. Having a system in place to recover easily from those disasters is important.
