Why is the boot prompt memory error

The following information lists common memory error codes and simple fixes that can occur. The resolution principle of hardware failure follows the principle of first soft and hard. First, you need to find the software problems that may cause problems, and then the reasons for the hardware, such as blue and black screen is mostly hard disk or memory, but why is it caused? Because the system files do not start properly, the problem is reflected in the software. As long as you make sure that your hardware is connected correctly, there is no virtual connection problem. Often the problem occurs on the software.

1. Boot Prompt "Cmosmemorysizemismatch"

"Fault performance" prompts for "Cmosmemorysizemismatch information" at power-on startup.

"Fault analysis" from the point of view, the BIOS found that the memory on the motherboard is different from the value stored in the CMOS, this error message is generated.

"Fault handling" starts the computer, enters the BIOS setup program, saves the exit correctly after setting.

2. Boot Prompt "Memorytestfail"

Failure performance post, the screen appears "Memorytestfail" and gives a "pressf1continue,ordeltosetup" message.

Fault analysis This error message indicates that a failure occurred while detecting memory. This failure is mostly due to the use of different brands or different operating frequency of the memory bar, resulting in compatibility problems, may also be the memory slot problems.

"Troubleshooting" can be resolved in the following ways, depending on the different causes that may cause the failure.

⑴ follow the prompts, press the "F1" key to continue to start the computer, if you can enter the system, but found that the content of the display is less than the actual installed memory bar capacity, the fault is entirely due to multiple memory strips between the

Compatible, you can resolve this problem by using memory with the same frequency as the brand.

⑵ if the "F1" key does not normally enter the system, it indicates that there is a serious memory failure. You should first test the single memory bar to troubleshoot a single memory stripe. Then combine multiple root memory strips for further testing to find incompatible memory strips

。

⑶ If you determine that the memory bar you are using does not have a compatibility problem, you will need to further check the memory and memory slots on the motherboard for damage, as these issues may also cause the failure.

3. Boot Prompt "Pressesctoskipmemorytest"

"Failure performance" after the boot will be a lot of memory detection, and give the "pressesctoskipmemorytest" prompt information, press the "ESC" key to skip memory detection, continue to start the computer.

Fault analysis detects memory multiple times and prompts for information because the fast power-on Self-Test feature is not enabled in the CMOS. The prompt does not appear as long as the feature is enabled.

Troubleshooting to enable the Fast power on self-test feature, you can follow these steps.

⑴ start the computer press "Del" key to enter the CMOS Setup program, enter the "Biosfeaturessetup" setting option, move the cursor to the "Quickpoweronselftest" Item and press "PageDown" key to change its value to "Enabled

”。

⑵ press the "F10" key to save and exit the CMOS Setup program, the message will not appear when you restart your computer.

4. Boot Prompt "Waring:spdnotfoundatdimme"

"Fault Performance" computer startup error, unable to start normally. The error message is "Waring:spdnotfoundatdimme".

"Fault analysis" most SDRAM memory with SPD, it is an EEPROM on the memory chip, including some of the memory of technical indicators (such as capacity, operating frequency, speed, voltage, etc.).

When the "Fault handling" computer is started, the parameters of the memory SPD may be automatically read according to the BIOS settings, and if the memory does not have SPD, an error will be given. At this point, you should review the motherboard instructions to disable the relevant options in the BIOS.

5. Boot Prompt "Error:unabletocontrola20line"

"Fault Performance" after the computer boot system error, can not start normally. The prompt message is "Error:unabletocontrola20line".

"Fault analysis" this hint indicates that there is a problem with memory, possibly bad contact between hardware, or memory hardware failure, or the control circuit of the motherboard.

"Troubleshooting" Should first check the memory and motherboard, clean up dust and rust, and reseat. If not, replace the memory test, if the failure disappears, the memory has a quality problem, you need to replace the memory bar.
