How to get to the central eco city from the railway station

at present, there are two ways to realize "multi GPU" technology: one is to install two GPUs on the same PCB, and realize SLI / CF in the graphics card, such as gtx590 and hd6990, which are "al core graphics cards"; Another method is to insert multiple graphics cards into the same computer and connect them with SLI bridge / CF bridge. Each graphics card can be either single core or al core
-
when two graphics cards are put together, they can't form SLI, so they can't be used together. For example, two gtx980 or two gtx970 are needed; The most important thing is that the motherboard should support NVIDIA's SLI, otherwise it is a waste of money
-
two cards of the same brand and the same model are the best. Just like the memory, the former scheme is not feasible, because the two SLI control chip versions are different, the stability will go wrong, and the performance will be disappointed< br />
in addition:
SLI is the multi card interconnection technology of NVIDIA chip graphics card. The mainboards supporting SLI include Intel X58 (some models), Intel p55 (some models) and Intel p67 (some models)<
crossfire is a multi card interconnection technology of AMD chip graphics card, which is supported by AMD chipset motherboard and Intel's X58 / p55 main chipset motherboard
OK, well, there is a last resort. To support SLI on the motherboard of AMD chipset, there is an unofficial way:
download the patch to crack NVIDIA SLI: slippatch_ v0.91_ Beta, can support 258.96 or lower driver
the specific use method can be as follows. Success is not guaranteed.
If two independent graphics cards want to be used on the same computer, they must have the following conditions
1, two graphics cards of the same model with the same board type are necessary. Different models can not, because amd graphics card is called crossfire, NV graphics card is called SLI, such as fine gtx970 can be SLI
2, the motherboard must have two or more PCI-E expansion graphics card slots, and the motherboard has passed SLI or crossfire certification
3, there must be enough high-power power supply to improve the sufficient power guarantee for the normal operation of the graphics card
4, install the graphics card on the motherboard, install the driver to run, find the display adapter in the control panel, and then use it after setting up the crossfire
it has nothing to do with graphics card. If you use GPU renderers, it has something to do with your graphics card, that is to say, It depends on which render you use to decide whether you will use your graphics card or not!
Second, you are absolutely right
if you have any questions, please leave a message
I will answer them
gpu-z and Dongdong detect the driver version
1. BIOS detects the BIOS version of the graphics card or (generally referred to as the BIOS of the flash card)
2. If the driver is installed in the system, the constant update of the graphics card driver will proce the version number!
the two sockets can be divided into x16 or not. A card does not need the same model for fire fighting. It is OK to have a golden finger for fire fighting. N-card needs golden finger and the same GPU chip, which is not called crossfire or SLI
