Is it possible to insert dual graphics cards on the motherboard that supports SLI technology?

This is indeed the case, because only SLI supports dual-SIM interconnection technology, and the popular interface type now is PCI Express 16X, and the native PCI Express 16X can give full play to the practical advantages of SLI!!

There are many motherboards on the market, and many of them support the latest SLI dual graphics card technology, which is to maximize the display performance of the whole machine by using dual bandwidth!

The requirements for SLI are higher, requiring two or more graphics cards to do SLI with the same core and video memory, and it is best to have the same board type and even BIOS, which is basically the same as symmetrical dual channels, and try to ensure that the two cards are exactly the same.

2.If it's the same, then the next step is to insert both cards into the two PCI-E slots on the motherboard, and then see that gold finger in the top left corner of the front of the graphics card? That is the SLI bridge, you need to put the SLI bridge connector that comes with the motherboard (that is, a small board with two interfaces, if you don't go to the computer city to buy a flexible cable version) on the SLI bridge of the two graphics cards.

3.Check the interface bandwidth settings of the motherboard, you are not familiar with your motherboard, but there are generally 3 different ways for motherboards that support SLI:1

The bandwidth switching chip is used, and there are only a few chips in the middle of the two PCI-E interfaces in this way, which looks very "empty", and the bandwidth will be automatically split after inserting two graphics cards, which is very convenient (common with ASUS and GIGABYTE). 2.In this way, there will be a lot of jumpers between the two PCI-E interfaces, and you need to adjust the jumper to split the bandwidth according to the manual (common for second-line manufacturers).

3.Bandwidth switching card is used, in this way, there is a circuit board with gold fingers at both ends between the two PCI-E interfaces, and the bandwidth is switched through different insertion methods (common for MSI and Shengji).

4.Once everything is done, it's easy to reinstall the system, install the newer drivers from NVIDIA, and SLI will automatically turn on if nothing else. You can use the GPU-Z or NVIDIA driver control panel to check the NVIDIA SLI options, if it is enable or enabled, then it is enabled successfully, if it is disable or disabled, it is not successful.

First go buy a cable for the SLI Plug in the first card for the monitor The driver of the SLI NV has to be adjusted.

Plugging in the graphics card is SLI mode. There is no need to debug again.

Install the driver and plug it into the main graphics card.

Then reboot. ok

Whether the motherboard can insert dual graphics cards is related to the number of PCI-E slots on the motherboard, and several slots can insert several graphics cards.

SLI technology is a technology of dual card parallelism, this technology requires more than two graphics cards, a motherboard that supports SLI technology, and multiple graphics cards need to be connected together with a cable, and these three conditions can be met to achieve dual graphics cards.

Specifically:

If a motherboard has only one PCI-E slot, it is impossible to insert two graphics cards, and the first condition is not met.

If the motherboard has more than two PCI-E slots, but does not support SLI technology, the second condition is not met, and even if two graphics cards are inserted, only one of them can be used.

In addition, it should also be noted that although some motherboards support SLI technology, the bandwidth of dual graphics cards is also different, PCI-E channels are divided into X16, X8, X4 different bandwidths, when dual graphics cards, the use of X8+X8 two channels is better than X16+X4 two channel performance.

This is indeed the case, because only SLI supports dual-SIM interconnection technology, and the popular interface type now is PCI

16x, native PCI

16x to take advantage of the practical benefits of SLI!!

First of all, it is not recommended to have such a low graphics card group SLI, because the power consumption is huge and the performance is low.

Secondly, some basic common sense about SLI:

The vast majority of games and software do not support SLI or Crossfire, try to use a single card when the performance of a single card is sufficient, and try to avoid using a single card or SLI. This thing is more used for running scores, or for some enterprise software, scientific research software computing work, and does not have much practical significance for home use.

In quite a few pieces of software, SLI not only doesn't improve at all, but instead causes a decrease in stability.

Secondly, from the point of view of cost performance, 560SE is currently an obsolete product, and the running scores of the two 560SE together cannot catch up with a 970, which is a world of difference for software and games that do not support dual cards.

If it's just to save money, sell your old card and exchange it for a 760 or R9 270 tier or higher.

Third, if you must try to play SLI, pay attention to a few points:

1 Must be of the same brand, model, and memory capacity. All parameters should be consistent. It's not the same and sometimes it can be successful, but it's very, very, very unstable.

2 Check whether there is a SLI bridge on the graphics card, whether it supports SLI, there is a row of short "gold fingers" on the opposite side of the gold finger, which is used for SLI. Usually versions of 560SE support SLI.

3 After the graphics card is connected through the SLI bridge, it is equivalent to a graphics card after setting, and the monitor can be connected to the main card (the first PCIe slot).

4 Does the motherboard support it? This is important. If your motherboard has only one slot, it can't SLI.

If there are two slots, in principle it is possible, but pay attention to the bandwidth of each slot, usually the main slot is 16x. If the secondary slot is only 4X, it's basically no fun, and the performance of the graphics card out of this SLI is not as good as a single card. The motherboard must support at least 8+8 mode to form a normal SLI.

Because the performance of a graphics card is largely limited by bandwidth.

The A card of the same level as the 560 is the HD 6870, which is also a lower performance elimination card, and there is no point in group SLI. Just get a mid-range graphics card at the thousand-yuan level to surpass the performance of this SLI. (There is no comparison for software that does not support SLIs).
