ASUS A8N5X plugs in three RAM 50s

Your board supports inserting 3 512 at the same time, but you need to consider memory compatibility when mixing 3 memory.

The biggest impact on compatibility is the encapsulation technology of the memory.

Some memory uses BGA packaging technology (you can't see the memory particle pins), and some use TSOP packaging technology (you can see the memory particle pins), because the electrical interfaces are different, and there will definitely be problems after mixing for a long time or they can't be identified at all.

I didn't pay attention to this problem at first, and mixed it up with Kingston and Kingmax, and it ended up getting a blue screen of death after a week. Later, kingmax was used uniformly, and it was quite stable.

Choose 3 memory with the same brand, the same frequency, and the same packaging technology to ensure that there is no problem.

If all three are Kingston DDR400 (all three should be single-sided, do not mix single-sided and double-sided), then wonder if there is a problem with the memory slot. Yours is the nForce4 chipset, which supports 3 DDR400 strips in terms of specifications

But it is rumored that the 4 memory slots hosted by A8N5X can only be used in pairs, that is, either two or four are inserted, otherwise they will not be recognized. However, it is impossible to verify whether this rumor is true. Anyway, ASUS officially did not admit it. )

Can't pass the self-test?

1. You first make sure that your 3 memory modules are good.

2. You try it one by one to see which one is bad, if it is all good, you first plug in two or two, and try it in a different slot, if it doesn't work, it means that it is not compatible, then there is no way.

1. The motherboard uses a standard voltage DDR3 memory slot (, a low-voltage DDR3L memory that can be used theoretically.

2. However, at this time, it should be in a state of supercharging DDR3L memory, if the memory is poor, it may not work properly (blue screen, restart, etc.), then this will only be known if you have tried.

The motherboard can use memory, but it is not recommended.

This motherboard is a desktop motherboard, and it normally supports the standard version of DDR3 memory.

The memory is a low-voltage version of DDR3 memory, if it is used on this motherboard, it is pressurized and can be used, but it may have an impact on the memory life.

The A85XM-A supports DDR3 memory. If you use DDR3L memory modules, the temperature may be high and the compatibility will not be good.

Let's talk about the role of a socket on your motherboard

The two pairs (two blue and two black) below the CPU are memory slots (support dual-channel DDR400);

The first blue one on the left side of the CPU is the graphics card slot (PCIe16X working mode), which is used to insert PCIe graphics cards;

The two short white ones on the left are also PCIe slots (only working in PCIe1X mode), which are used to plug in other PCIe devices, such as PCIe network cards, etc.;

The black one to the left is the graphics card slot (PCIe4X working mode), which means that your motherboard supports dual graphics cards!

The three same white ones on the left are PCI slots, which are used to insert PCI devices, such as network cards, sound cards, etc.;

Further down to the left, there are four small blue slots on the left edge of the motherboard, which are SATA hard drive sockets, and your motherboard supports disk arrays!

There are two IDE disk sockets of the same size (one black and one blue) under the memory slots mentioned above, the slightly right one (black and smaller) is the floppy drive socket, the white honeycomb (24-pin) is the motherboard power socket, and the square (four-pin) one on the upper right side of the motherboard is also the motherboard power socket;

God, even if you didn't look at it, I'd be stunned!

All in all, your motherboard is good!
