Several common memory bios failure phenomena and solutions

Memory is the work of the computer runtime "warehouse", memory failure in the computer failure accounted for a considerable proportion. and memory failures are sometimes more covert, more trouble to judge. Standard for you to introduce some common memory bios failure phenomenon and how to solve the method. Hope to bring you a little help.

　　1. Memory Test Fail

After the computer is powered on, the self-test message is "Memory test Fail", which means that the memory test failed. Usually this situation is due to memory incompatibility or failure caused, so each boot with a memory test, to find out the memory of the fault, take it off or repair can be.

　　2, memory detection time is long

On the boot of someone else's computer memory only test once, and your computer is detected three times, memory detection time is too long, how to let the memory detection quickly up?

Now the memory capacity is increasing, the boot memory self-test time is more and more long, even if the use of rapid detection, three times to detect the detection, time is not short. But we can boot, press "Del" key to enter the setup option, select BIOS Features setup, press ENTER, use the "Page down" key to "Quick power on Self Test" set to "Enabled", using "F10" The key exits (answer "Y"). Press the ESC key to skip the self-test when the post is in memory.

　　3. Frequent "Illegal operation" error occurs under Windows

I have a KT133 motherboard, using ordinary HY PC133 128MB memory computer, download an optimized BIOS setup program to optimize the BIOS, but after optimization, in Windows frequently "illegal operation" error, how to solve it?

In general, the BIOS optimizer optimizes the BIOS in a comprehensive way. From the configuration above, the memory is ordinary HY memory, is not too good, so enter the BIOS, will be found in the "Advanced chipset Features", the BIOS optimizer has the "SDRAM Cycle Length" item set to 2. If we want to stabilize, we just change 2 to 3, then "Bank interleave" from "4Bank" to "Disable", and then restart the machine.

　　4, the memory is 256MB, why display "261120k+1024k" information?

This is due to the use of integrated video cards. With the video card integrated on the motherboard, the video card will share memory with the motherboard. In turn, the content displayed when the memory self-test is different from the normal motherboard display. The normal motherboard displays only one memory capacity (the actual value), and the motherboard for the integrated video card displays "261120k+1024k Shared Memory", where 1024K is used to display the cache, as shown in Figure 1.

　　5, modify "DRAM Timing by SPD" why black screen

Use epox Pan EP-8KTA3 motherboard, the BIOS in the "DRAM Timing by SPD" option to "Disabled" when the computer will have a black screen phenomenon, and the "DRAM Timing by SPD" set to "Enabled" when the computer use everything normal, What is this for?

This is actually a bug in the Epox ep-8kta3/8kta3+ motherboard, we can upgrade the motherboard BIOS to resolve this "detect SDRAM size problem", you can go to http://file.mydrivers.com/bios/ 8kt31305.exe download revision bios for upgrades.

　　6, 256MB SDR after the memory installation why only show 128MB

My computer is Lenovo days Hi brand Machine, the motherboard is 810, now want to expand the memory, bought a 256MB SDR memory, but installed up to only show 128MB.

Such problems appear more on the motherboard of the Intel810 chipset. This is because 810 of the Intel chipset does not support single-sided 256MB memory booting, and 810E and 815, 820 after 810 are supported. So the way to solve the problem is to replace the single 256MB memory with double-sided 256MB of memory on it.

　　7, the original 128MB memory, insert a 64MB after the total amount of memory is only recognized 64MB

Computer configured for 815EP motherboard, 128MB memory, the original use of normal, and then get a 64MB of memory, together with the plug, the total amount of memory is only recognized 64MB it?

The memory is inserted into the motherboard, the verification is good, you can eliminate the quality of memory issues, it appears that the compatibility problem again. For such a memory compatibility failure, we generally can upgrade the motherboard BIOS to solve, to the motherboard manufacturer's website to see if there is a new BIOS upgrade.

　　8, after adding a PC133 memory, why frequent panic and hot-restart

Recently I have added a PC133 memory to the computer (the original memory is PC100 memory), the runtime is frequent crashes and Geixi.

This situation is generally due to the addition of memory and the original memory, brand, speed, capacity is different or some different, the solution can use the "low" principle. Into the CMOS, in advanced chipest features see DRAM Timing by SPD is set to "Enabled" to modify it to "Disable". Then the DRAM clock to 100MHz Restart the computer, you can solve the above fault. If not, you can try to replace the memory slot, generally to the faster memory plug in the first slot. If all the above methods fail, it is recommended to update the BIOS of the motherboard under DOS, the general problem can be solved.

　　9. Why error Himem.sys file at startup

The computer does not enter Windows 98 and shuts down immediately after entering the system. Start in Safe mode, read Himem.sys prompt "Error:HImem.sys has delected unreliable XMS at address XXXXX ...", How to solve?

Depending on the hint, the issue should be related to the motherboard or memory. Because the prompts indicate that there is an error in memory when the Himem.sys file is started, you should generally isolate the problem from memory. You can try the following methods at this point:

(1) The simplest way to set the parameters in the BIOS to be conservative is to use the default BIOS parameters.

(2) can try to use discharge mode to clear the information in the CMOS memory. If none of the above methods, it is recommended to send the motherboard repair point or direct replacement.

　　10. Why not enough memory when upgrading bios

There is not enough memory to upgrade the BIOS, and I only use a clean system disk plus the upgrade file floppy boot, can not have a virus, and no other programs to run, how can not have enough memory?

Such a failure is actually a dblspace.bin file in the mischief. We can insert a tool disk, with MEM/C view, you will find that there is--"Dblspace" program, the original Windows disk compressed file Dblspace.bin (this file in the C-packing directory) string into memory! Start with a floppy disk, How does a program on your hard disk string into memory? Don't believe it, it's the truth! With attrib to remove its attributes, and then copied to other directories, and then the original C-packing directory of deletion, the upgrade disk to guide, you can safely upgrade the BIOS, upgrade finished and then restore the file can be.
