Plug in the second memory and it will be black screen 25

Two incompatible puts, it's normal, insert two back like this, or plug in one, or ask a professional person to see what kind of buy, didn't you say, what is the way to be incompatible, if you don't want to buy, find your friend someone to use one, and he exchanged, one rarely exists incompatible.

Give points, don't be stingy.

It's not a strip, it's an incompatibility between the motherboard and the strip, and for you, that's not a matter of strips!

This should be a matter of memory, you look at it differently, if you want to use it together, you need the same memory.

In this way, the two strips cannot be used together. You can only choose one.

Incompatible, inconsistent memory chips.

The brands of memory modules are different, regardless of the size of the capacity, they cannot be mixed together, and the performance indicators are different and incompatible.

Performance metrics for memory.

There are four performance indicators to evaluate memory modules:

1) Storage capacity: that is, the amount of binary information that can be contained in a memory module, such as the storage capacity of the commonly used 168-line memory module is generally 32 megabytes, 64 megabytes and 128 megabytes. DDRII3 is generally 1GB to 2GB.

2) Access speed (memory cycle): that is, the minimum time required between two independent access operations, also known as memory cycle, the access cycle of semiconductor memory is generally 60 nanoseconds to 100 nanoseconds.

3) Reliability of memory: The reliability of memory is measured by the mean time between failures, which can be understood as the average time interval between failures.

4) Performance ratio: Performance mainly includes memory capacity, storage cycle and reliability, performance ratio is a comprehensive index, for different memory has different requirements.

Use an eraser to clean the gold finger of the memory, and clean the dust of the memory slot on the motherboard, which may be due to poor contact caused by dust.

If you go to CMOS and set the memory clock speed to by SPD or auto, Kingston's memory should not be recognized, so you plug in two and actually only recognize one;

It is recommended to insert only one Kingston, and there should be no problem with plugging in the original Lenovo after the problem is solved;

If it still doesn't work, it may be that there is a problem with the Kingston memory module itself, you can change the memory and try again.

It is recommended that you plug in the two memories separately to see if they are all good, check whether the slots are broken, and the computer supports the memory capacity. There is also a black screen if there is dust at the memory contact point, the probability is relatively large, wipe it with a clean cloth, and insert the memory.

In a word, the memory is incompatible or broken. That's it if you want to try. Remove the original memory on your original machine and try it with your new memory. You can try it out as soon as you try it. Memory incompatibility.

1. If.

The installation of the memory module is not in place after wiping, for example, the clamps on both sides of the memory module are not completely in place, and the gold finger of the memory module does not enter the slot accurately.

Poor contact. Therefore, you need to shut down, unplug the power, and then plug and unplug it again, pay attention to the downward insertion of the memory module, see that the notch of the memory module is aligned with the slot, and insert it downward, you need to hear the "click" sound of the bolts on both sides to be stuck. The bolt will.

Automatically locks the memory module.

2. Check whether the power cord contact is normal before turning on the machine. Whether the power cable and plug of the hard disk are in good contact, and make sure that there is no problem, try it after turning it on. If the fault persists after booting, then you need to change the memory module to a slot, because there is dust in the slot, which will affect the boot.

You can try again with a different slot. Turn on the computer and see if you can enter the boot screen.

3. If this is still the case, I am afraid that the system needs to be reinstalled.

1: Unplug the power supply and disassemble the chassis.

2: Unplug the graphics card, wipe the metallic strip under the graphics card4: Plug in the power supply, and turn it back on.

If the memory module is broken, the computer can't be turned on, the monitor will display normally, because some cases are easy to get into the dust, resulting in the graphics card, it is easy to make mistakes, it is recommended that if the conditions allow, 3 months, use a hair dryer, clean up the chassis, you must use cold air, otherwise the hot air will burn the internal parts of the case, and my computer will not be used for half a year. Unplugging the memory module with power turns out to be black. Is it the motherboard that is broken, and the answer is yes.

Question: If you don't have a discrete graphics card. It's an integrated graphics card.

Can it be fixed?

You can fix it and find someone to fix it.

Question: Do you know if it's bad?

The host is broken, and you can ask questions.

From the phenomenon you described, any single memory can run normally, which means that the motherboard can be recognized by the memory module, but the two memories are incompatible when used together, even if it can be turned on occasionally, there will be a crash or blue screen phenomenon in the process of use, if you insist that you want to use the double memory at the same time, it is a problem that cannot be solved, if you want to upgrade it, you can only try to replace one of them to try the method.

It's just that these two memories are incompatible.

Insert the memory module into the two memory slots separately, and the trial is no problem, which means that the two memories are good, the four memory slots on the motherboard are easy to use, and the exchange memory slots are not good, and my analysis is that these two memories are incompatible.

Memory is like this, that is, two memories of the same brand, the same batch, the same frequency, and the same capacity from the same factory, and when they are put on the same machine, there will also be memory incompatibility. If you want to increase the memory, you can only change the memory module, and it is best to go to the physical store to exchange it and try to add it.

Re-insert the memory module, graphics card, CPU power plug, radiator, fan, especially the memory module is in poor contact, the screen is black and alarm, if the CPU radiator and cooling fan are in poor contact, the system will detect that the temperature of the CPU is too high, and it will shut down for protection.

Whether there are two memories in the first place, or if one memory is added later, if this is the case, it is recommended to reinstall the system. My computer used to have this problem when adding memory, and it was solved after reinstalling the system.

It means that the frequency is too high, and the motherboard does not recognize it, or it has encountered compatibility problems.

1. The memory module of the notebook is limited by frequency. Generally, it is up to one level crossed. For example, if the standard supports 1066, it can generally only support up to 1333, or double-sided. If you are on 1066, you may not recognize it.

2. Notebook memory modules, if two are used together, will automatically form a dual channel. However, if the speed of the two is too mismatched, there will be compatibility problems, resulting in failure to boot.

3. It is not excluded that the memory slot has been idle for a long time and has poor contact. Plug in a single one to judge.

It may be that the two memories are incompatible, and it is recommended to warrant it during the warranty period.

Preliminary suspicion that inserting two at the same time is too much memory to exceed the standard, you can try it with a small memory!!

Quite simply, the motherboard does not support dual-channel 16G

If you want to upgrade the memory, it is best to choose a model of the same specification, which has good compatibility.

What to do if the computer starts up with a black screen.

You take out the memory module and clean the prongs with a clean bucha. The sockets on the motherboard should also be cleaned.

It is most likely due to poor contact. If there is still a problem, it is possible that the memory module socket is in poor contact, and the motherboard needs to be replaced.
