Teach you to add a memory stick after the system time error solution

Memory is one of the core components of a computer, and its importance is self-evident. At the same time, memory is also the main source of computer failure, and the consequences of memory failure cannot be ignored. Here to analyze the problem of system time error after adding memory, I hope that you can learn the ideas and methods to solve the memory failure.

Symptom:

My computer originally only had a 32MB memory stick, and later bought a 64MB memory stick upgrade. The first few months after the memory module was bought, everything was normal, but since February of this year, somehow, the system time is always more than 10 hours slower than the normal time (similar to the fault phenomenon described in the 31st issue of Computer Newspaper). However, my computer is more ill —— sometimes the information of CMOS settings will be lost, and these two faults do not appear at the same time, sometimes you can enter Windows 98 when booting, but the time must be wrong, the difference is more than 10 Hours; sometimes boot will prompt CMOS content is lost, can not enter Windows 98, but if you enter CMOS reset, you will see the CMOS record time is correct. Every time you turn it on, you have to adjust it. It's really troublesome to adjust the CMOS content instead of adjusting the time.

Analysis and repair:

At the beginning, I also think that the CMOS battery is exhausted, but I can buy a new one and the fault remains. Clearing the CMOS information can eliminate the fault, so the jumper on the motherboard is found to clear the CMOS information. However, the method of working on the original author's motherboard has no effect on my motherboard. The original text said that the BIOS can be updated, but my BIOS version is the latest, and there is no new BIOS on the motherboard manufacturer's website. I really can't help it.

But I stumbled upon the cause of the problem. My friend thought of trying the memory stick on my computer to see if there is any problem with his memory stick, so he took off my 32MB memory stick and plugged two 64MB memory sticks into my motherboard, but the boot self test. The computer only recognizes 128MB of memory and 64MB less. What is going on? I suddenly thought, is it because his memory stick is PC 133, and my 64MB memory stick is PC 100, so my memory stick is not working? Yes, in CMOS settings It seems that one item is related to the memory slot. I quickly restarted and entered the CMOS settings. There are three items corresponding to Bank 0/1, Bank2/3, and Bank4/5 DRAM Timing. Now the settings are Fast, adjust them to Normal, save them, and reboot. Sure enough, at the power-on self-test, you can see that it is 192MB of memory. The friend's memory is no problem, so he pulled it and took it away. When I am ready to plug in my 32MB memory, I think about the process just now. Is it because of this reason, my computer has a timing error? Re-set the CMOS information and system time, and put Bank 0/1, Bank2/3, Bank4/5 DRAM Timing is set to Normal, shut down, see if there will be an old problem. After a day, everything is fine, all CMOS content and time are completely correct. I also adjusted the Bank 0/1, Bank2/3, and Bank4/5 DRAM Timing settings to Fast? Sure enough, the contents of CMOS are lost when you turn it on again. The real reason is here.

After the memory is added, the system time error has occurred. Many friends have encountered it. In addition to the methods introduced, look at this article, and the memory speed setting is also very relevant!
