What does the 1Rx8 mean vs 2Rx8 for RAM and are they compatible?

7 Answers. 1Rx8 means it is a single-rank module and 2Rx8 means it is a dual-rank module module. Rank is a data block which is 64 bits wide without Error Correction Code (ECC) created using some, or all of the memory chips on a module.

Can I use 2Rx8 instead of 1Rx8?

8 ranks would be the maximum supported. Therefore, a single rank (1Rx8) would count as one, whereas a dual rank (2Rx8) would count as two, all of which would be added up to a total maximum of eight (8 times 1R or 4 times 2R, or any combination, thereof, that would total “eight”).

What is 10600S in RAM?

10600S: Effective Clock Rate OR FSB – more popularly measured as 1333 MHz. 9-11-FP : Memory chip timings – CAS Latency.

Can you use any RAM together?

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.

What determines RAM compatibility?

Your computer’s motherboard will also determine RAM capacity, as it has a limited number of dual in-line memory module slots (DIMM slots) which is where you plug in the RAM. Motherboards support only one, and which one mostly depends on how old your motherboard is.

Can I use single stick RAM?

You can put only one in. Dual channel is a feature saying you can run the RAM in a “Dual” or “Single” channel mode. It has a few different effects, but the only important effect of note is being able to put more RAM in. If you want to use only one single RAM stick there will be no issues.

Can I mix PC3 10600 with PC3-12800?

You “can”, but it may cause major instability. It is good to have the same manufacturer and revision, but if you set them both down to the lowest settings, for example, 1333, 9-9-9-24, 1.5v or whatever the slowest is speed for, they should run fine.

Is PC3 and DDR3 the same?

PC3-12800 (12800 MB/sec) is the same thing as DDR3 1600MHz (1600 MHz data transfer rate) and it runs at 800 MHz DDR clock. Similarly for others, just divide/multiply by 8. Any memory that has the correct voltage and capacity and is same or faster than what is supported by the board should work in the board.

Is PC3 and DDR3 RAM the same?

Is DDR3 the same as RAM?

DDR2 and DDR3 are types of RAM, Random Access Memory. DDR RAM offers speed of 1600 MB/s, DDR2 RAM offers speed of 3200 MB/s and DDR3 offers speed of 6400 MB/s. DDR3 provides 8 knowledge transfer per cycle.

What are the different types of memory (RAM)?

What are the different Memory (RAM) types? The most popular forms of memory modules are commonly known as DDR4 and DDR3, DDR2, and DDR. SDRAM is a generic term for much older pre-DDR RAM technology, with most systems that use this type of RAM since retired.

What type of DDR3 memory does the motherboard support?

The motherboard supports DDR3 memory that features data transfer rates of DDR3 2200 (O.C.)/2133 (O.C.)/2000 (O.C.)/1866 (O.C.)/1600/1333/1066 MHz to meet the higher bandwidth requirements of the latest 3D graphics, multimedia, and Internet applications.

What are the different types of DDR memory speeds?

DDR Memory Speeds and Compatibility. 1 Generations of memory explained. For double-data-rate memory, the higher the number, the faster the memory and higher bandwidth. Occasionally DDR 2 DDR4 speeds. 3 DDR3 speeds. 4 DDR2 speeds. 5 DDR speeds.

What is a 2R memory rank?

To explain this, you need to understand that a “memory rank” is a 64-bit row of memory chips on a memory module. 2R = two memory ranks per module. 1R = one memory rank per module. 2R memory is often called “dual sided”, as the chips for the different ranks are usually put on opposite faces of the module.
