8GB DDR3 1600/12800mhz Desktop RAM

This memory is fully compatible memory. It can be used on AMD, Intel ordinary desktop motherboards. Can also be used for server motherboards such as X79 X58. Two different types of memory generally cannot be used on the same motherboard

1. For example, G41, P41, N68, P55 and 775 interface motherboards cannot use any 8GB memory model of this link

2. For example, H61, H55, G61 and 1155 1156 interface motherboards cannot use the 8GB memory model of 1RX8 (single-sided 8 chips), they can use the 8GB memory model of 2RX8 (double-sided, 8 chips per side, total 16 chips).

3.The reason is that some motherboards cannot read some chips with too large a capacity. For example, an 8GB single-sided memory, a total of 8 chips, each chip contains 1GB capacity, some older motherboards (such as H55) cannot read it. But, an 8GB two-sides memory which is total 16 chips, each chip is 512MB can be read.

4.Regarding the memory frequency was originally 1600mhz, but the memory you received can only be read at 1333mhz. Most of the time, it is not a memory problem, but the motherboard and processor are not strong enough to read so much memory. For example, the maximum supported frequency of a motherboard or processor is 1333mhz, even if the memory with a higher frequency is installed, this motherboard can only read 1333mhz

5. If you are not sure about the computer model, you can install CPU-Z to detect the computer’s motherboard and processor model, then take a screenshot and leave me a message. I will recommend the most suitable memory.

Double Data Rate Synchronous Dynamic Random-Access Memory (DDR SDRAM) is a double data rate (DDR) synchronous dynamic random-access memory (SDRAM) class of memory integrated circuits used in computers. DDR SDRAM, also retroactively called DDR1 SDRAM, has been superseded by DDR2 SDRAM, DDR3 SDRAM, DDR4 SDRAM and DDR5 SDRAM. None of its successors are forward or backward compatible with DDR1 SDRAM, meaning DDR2, DDR3, DDR4 and DDR5 memory modules will not work in DDR1-equipped motherboards, and vice versa.

Compared to single data rate (SDR) SDRAM, the DDR SDRAM interface makes higher transfer rates possible by more strict control of the timing of the electrical data and clock signals. Implementations often have to use schemes such as phase-locked loops and self-calibration to reach the required timing accuracy.^[4][5] The interface uses double pumping (transferring data on both the rising and falling edges of the clock signal) to double data bus bandwidth without a corresponding increase in clock frequency. One advantage of keeping the clock frequency down is that it reduces the signal integrity requirements on the circuit board connecting the memory to the controller. The name “double data rate” refers to the fact that a DDR SDRAM with a certain clock frequency achieves nearly twice the bandwidth of a SDR SDRAM running at the same clock frequency, due to this double pumping.

With data being transferred 64 bits at a time, DDR SDRAM gives a transfer rate (in bytes/s) of (memory bus clock rate) × 2 (for dual rate) × 64 (number of bits transferred) / 8 (number of bits/byte). Thus, with a bus frequency of 100 MHz, DDR SDRAM gives a maximum transfer rate of 1600 MB/s.
