nVIDIA Dual Graphics SLI Technology

If one does physics and the other does rendering, the performance does not superimpose It can't be regarded as a real SLI dual card If you have dual cards, it is still better SLI performance First of all, you have to see if there is a bottleneck on the platform If you are on a graphics card at this level of 280, then you need to be Core 2 quad-core or above or Pterodactyl 2 dual-core or above to barely have a bottleneck If you look at your graphics card alone, your platform configuration should not be very good It should be about the Pentium dual-core series Let's see if there is a bottleneck in the planning.

In GTX200 has been fully rolled off the assembly line No one spends about 1500 to buy GTX280 1500 or so can buy a first-line brand of GTX4601G version Whether it is heat and power consumption, as well as performance and overclocking space, it is definitely over 280 Even if you want to group SLI, you can also choose the new GTS450 Dual cards can be bought at about 1700 If you group SLI, the performance also feels super 280 And the group SLI motherboard must first support And you need to have two PCI-EX16 slots, if it is x16+x8, the performance will not be fully utilized.

And if you insist on not giving up your 9600gso, Kenneng will cause a bottleneck because of him, and 9600gso is still worth about 200 fast, and you can sell a new one together.

ps: If you have any questions, you can hi me or +q

It is recommended that you use GTX280 + GTS250, GTX280 is responsible for shadow processing and mapping, GTS250 is responsible for PHESX, GTS250's physical acceleration performance is still very good, but after all, it is a secondary card, you should plug the display cable into GTX280, and GTX280 is placed on PCI-E 16X GTS250 is plugged in on PCI-E 8X.

1. The operating system should use the pure version of 64-bit.

2. Keep the graphics card driver up-to-date.

Once you are in the NVIDIA Control Panel, click on the "Configure SLI, Surround, Physx" option.

Click "Achieve Best 3D Performance" on the screen, and then click "Apply" in the bottom right corner, so that the SLI function is enabled. We need to check whether the SLI function is enabled, and the software used is GPU-Z.

When the SLI is successfully formed, the text displayed is "Enabled", and it will show how many GPUs are in the SLI formation, and if the SLI fails, the part will be displayed as "disabled", indicating that the SLI has not been successfully enabled. The image shows "enabled", which means that we have successfully built the SLI platform. Seeing this step, our tutorial is actually basically complete.

The most critical part of building a dual-SIM SLI is naturally the construction of the platform. The premise of building a SLI platform is that your motherboard supports NVIDIA SLI, and some low-end motherboards do not have this function, so players who build a SLI platform must pay attention. In addition, when building a dual-SIM SLI platform, if there is a choice, of course, both cards are plugged into the PCI-E 16X slot, and if the graphics card is too thick to block the high-bandwidth PCI-E slot, it is not impossible to plug it into the 8X or 4X.

We've previously tested the impact of PCI-E slots with different bandwidths on graphics card performance, and the results show that the performance of the graphics card is similar on 16x and 8x slots, while there is a significant performance penalty on 4x slots.

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 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).

It's to use the same graphics card as one, and support SLI.

Graphics card SLI technology, don't be mistaken as just two PCI-E 16 slots.

1. Two A cards are called crossfire, and two N cards are called SLI on the same motherboard at the same time, which can only be done with the same model, that is, this must also support SLI on the graphics card itself.

2. This requires the motherboard not only to have two PCI-E x16 slots, but also to have Inter certified SLI technology on the motherboard before it can form an SLI.

Therefore, it is recommended that whether you are buying a graphics card or motherboard, you should consult the merchant to avoid the embarrassment of not being able to use it after buying.

Not necessarily, depending on what graphics card is inserted, N card SLI, the motherboard needs Nvidia authorization to support, generally N card authorized motherboard, usually the motherboard will be printed with the SLI logo.

If it is a A card, no additional authorization is required, as long as there are more than two motherboards on the motherboard that are PCIe16X, it can support crossfire.

Another way is to go to the official website and enter the motherboard model to check whether SLI technology is supported.
