Does it make sense to add a memory to a board that doesn t support dual pass?

Many people don't know that since the intel 915 motherboard, they have begun to support asymmetric dual channels, different capacities, and different brands of memory can still be grouped, but this technology is not mature until the 965 era.

It's completely necessary 512 liters 1g is much cooler than 1g liters 2g Ordinary operation can feel it The longer you look at the web page on the Internet, the more obvious it feels It's fast, and now the memory is cabbage price, why not add it If you usually have 10,000 games, chat a day and watch a movie or something, then it's more necessary to add it It's not what can be understood as 1g After adding, it's 1g It's better than a single 512 Fast and cool Ignore what dual channel is two 512 dual channels It's not much stronger than the double 512 that is not a dual channel The strong and the strong are extremely limited.

Now there are very few 2nd generation 512, but the effect of upgrading the 512 to 1g or more is the most obvious. Can be added!

To put it simply, a single insertion of memory is a single channel, and the bit width is only 64; At the same time, insert a double-numbered memory, according to the dual-channel insertion cavity tape, that is, dual-channel, the bit width is doubled, that is, 128 bits.

Dual-channel is the design of two memory controllers at the Northbridge (also known as MCH) chip level, which can work independently of each other, and each controller controls a memory channel.

A normal single-channel memory system has a 64-bit memory controller, while a dual-channel memory system has two 64-bit memory controllers with a 128-bit memory bit width in dual-channel mode, thus theoretically increasing the memory bandwidth by a sharp. While the bandwidth provided by a dual 64-bit memory system is equivalent to that provided by a 128-bit memory system, the results achieved by the two are different. The dual-channel system consists of two independent, complementary intelligent memory controllers, which theoretically can operate simultaneously with zero latency between them.

The dual-channel memory insertion method is particular, and it should be inserted into two memory slots of the same color. If the colors are different, they can't form a dual channel. Different capacities of memory can also be composed of asymmetrical duplexes.

DDR is 1st generation memory, while DDR2 is 2nd generation memory. There is the problem of single-sided and double-sided pulling. Generally, the same memory, single-sided is more expensive than double-sided. Also, single channel and dual channel, that depends on whether your board supports pull or not!

Dual-channel and single-channel are memory independent.

It depends on the motherboard chip, and the motherboard above 856 supports dual channels

Isn't there a label? It is written.

ddrddr2

Hit the wrong pull! It's a double one that's faster than a single one!

1. From 2006 onwards, as long as the motherboard has 2 or more slots, it supports dual channels;

2. Starting from K8, AMD's CPUs have built-in dual-channel memory controllers, which have nothing to do with the motherboard;

3. Intel platform.

The CPUs of the Core i7 series all have built-in memory three-channel controllers, which do not support dual-channel, and the corresponding motherboard is X58;

Basically, all CPUs with 45nm and 32nm processes have built-in dual-channel memory controllers, which support dual-channel (including Core i3 and i5), and the corresponding motherboard mainly depends on the CPU interface, as long as there are 2 memory module slots on the motherboard, dual-channel memory is supported.

Basically, whether the CPU of the 65nm and 90nm process supports dual-channel can only depend on whether the motherboard supports it, but Intel's motherboard has supported dual-channel memory since 865, and 915 has begun to support elastic dual-channel memory (that is, two memory sticks of different sizes can also form dual-channel).

AMD 250 Kuroshio BA218 supports dual channels, as long as you have 2 memory modules!

Gigabyte's and more recently Onda's motherboards also have dual-channel.

At present, it should be supported by all the mid-range and above, as long as it is not too cheap, the low-end should also be supported, or it will not be sold.
