As long as the types of Ram you mix are the same FORM FACTOR (DDR2, DDR3, etc) and voltage, you can use them together. They can be different speeds, and made by different manufacturers. Different brands of Ram are fine to use together.
None of this necessarily guarantees functioning RAM, of course—you may be greeted with the Blue Screen of Death if your DIMMs just don't like each other (or your motherboard doesn't like one of the DIMMs). Most of the time, though, your computer will run fine if you mix different brands, sizes and speeds.
What happens if you add two RAM sticks to your PC, and one has a bad SPD? A. When your system boots, it will recognize both RAM sticks but will not register any special features (such as ECC) of the stick with the bad SPD.
If you want to add more RAM than that, say, by adding an 8GB module to your 4GB module, it'll work but the performance of a portion of the 8GB module will be lower. In the end that extra RAM probably won't be enough to matter (which you can read more about below.)
RAM frequency is measured in MHz and usually immediately follows the DDR version in the RAM spec. For example, 8GB DDR4-2400 RAM is running at a frequency of 2400MHz. This is why though higher frequency RAM is technically faster, that additional speed often does not translate into better actual real world performance.
If you are building a new amd based system 3000 mhz will be the minimum ram speed you should go with,if you can afford any ram beyond that speed it would even be better(although not much) in gaming,as amd's infinity fabric architecture feeds off high speed ram with low latencies.
As for desktop, the maximum memory supported by computer is generally determined by the processor and motherboard. You just need to find out the maximum RAM speed supported by your cpu and motherboard, and compare them. The slower one is the maximum RAM speed supported by your desktop.
How do I tell the difference between dual and single rank modules? Multiply total number of chips (less any ECC chips) by the chip width. If it equals 64 its single rank. If it equals 128 its dual rank.
If you have four RAM slots, always buy matched pairs of RAM (two sticks from the same company, same speed, and same capacity) for the best results. So, in this case, where there are four slots, the RAM should have been placed in quantities of 2, 4, 6, or 8.
Depends on how many slots you have on the motherboard. If you have 2 slots, a single 16gb is better,since you can upgrade in the future easier. If you have 4 slots or you don't plan to ever upgrade, 2x8gb is better since that is faster and will increase the performance of your pc.
4x8 would be better if your system supports quad channel RAM, but most systems only support dual channel. Your 5820k supports quad channel so it's best to use increments 4 sticks. No different but touch wood if a stick of ram spoil, 8gb would be cheaper.
It is of course much better for performance to populate all memory channels. That is, it is better to use many smaller size RAM sticks to populate all channels than just a single or two large size sticks inserted into 1 or 2 memory channels.
The four sticks will just run through two channels. If you want to overclock it might be harder to get a stable clock or the stable clock will be lower. Otherwise there is no performance disadvantage to populating all the slots.
To answer your question yes you can use three sticks of ram, however you will not get the maximum performance from it like you will from matched pairs in dual channel. For stability & performance, never mix sets and always configure in dual channel mode.
Yes, it is advisable to use RAM sticks by the same manufacturer, of the same size, and of the same frequency. You can use 1 stick of RAM in a dual channel motherboard but it won't be running in dual channel mode, only single channel.
For gaming yes. Ok, nowadays, with modern/new games you will want 16gb of RAM. If you do more than just gaming (rendering/editing/graphical work), 32gb starts to become the minimum, 64gb the norm, and 128 for overkill (extreme usage).
If your motherboard has 4 slots for RAM, two 4GB sticks is better because you can already have dual channel, meaning faster memory. If your motherboard only has 2 slots for memory, and you want to upgrade in the near future, get the 8GB stick.
In the case of a motherboard with four RAM slots, it's probable you'll want to install your first RAM stick into the slot labeled 1. A second stick should go into Slot 2, which isn't next to Slot 1. If you have a third stick, it would go into Slot 3, which will actually be between Slot 1 and Slot 2.
When the RAM has the same specs like size, speed, they have little differences in performance, even they have different brands. Different brands use different kinds of memory chips and materials. So, they are a little different in quality but not performance. So, ram brand does't matter too much.
Generally speaking, the amount of RAM does not affect the FPS. RAM is used to store data that needs to be readily available for a program to run. More memory allows the program to have more data stored. Generally speaking, the amount of RAM does not affect the FPS.
What modules does it take? A motherboard with DDR2 slots will not fit any other types of RAM sticks. If your motherboard's memory capacity caps at anything above 8 Gigabytes, feel free to add an 8GB memory stick to your system. You can eventually replace the 2GB stick if your computer is still usable then.
Yes, you can mix 1333 and 1600 MHz RAM sticks, however the system will downclock all RAM to the speed of the slowest stick. For best performance, try and buy RAM that is the same speed or faster.
