Landlord, your motherboard has been out of order for a long time. It happened that DDR3 was not popular at that time, and DDR2 was still widely used. At that time, it was in the surplus stage, and the price of DDR3 was much more expensive than DDR2. At that time, many motherboards could support both DDR2 and DDR3.
Also, at that time, there was no single 8G memory, or rare varieties were sky-high, which the ordinary market could not afford. So the memory support at that time did not consider the capacity of a single 8G at all.
This motherboard has two DDR2 memory slots and two DDR3 memory slots. Two kinds of memory cannot be used at the same time. And regardless of DDR2 or DDR3, the total capacity can only support 4G, that is, a single slot can only support 2GB of memory at most. Only a single 4G memory is used, and only one slot can be used. See the specification is defined in this way, unless there is an updated BIOS, it is generally not available. Such transitional products have not been on the market for a long time and are not the absolute mainstream.
I mean the transition from DDR2 to DDR3, not the motherboard chip itself. Also, the mainframe that you came down from that period is relatively old. It is estimated that the graphics card is not a cow card, and the configuration is very general now. There is no need to consider the upgrade method of a single 8G memory.
No matter how large the memory is, there is no performance improvement in most applications. The bottleneck of the game is mainly the graphics card, and the transmission rate of the hard disk is also a bottleneck. Therefore, high-end game consoles are basically equipped with solid-state hard disks, and their performance has been significantly improved. Instead of frantically increasing memory capacity.
