Memory slot fault on m4a78lt-m

What can cause the slot to fail. I have tryed to see if the slot has been shorted or damaged the pins but I am unable to see. The problem started when I kept getting blue screen and restarting. I had done a complete diagnostic but for some reason It didnt show any faults. I also tryed swapping the memory and still nothing except data lock now the slot is inactive.

Sounds like a bios issue. Try resetting the bios, pg. 2-19 in user manual. After clearing the bios jumper, make sure you set it back to pins 1 & 2. If you still can not get into the bios main menu than head to Asus, click this link.
http://support.asus.com/download/download.aspx?modelname=M2N-E%20SLI&SLanguage=en-us
Since this is a new board & all Asus boards are warranted for three years I suggest you talk with an Asus tech. If you flash you're bios during the warranty period you may void the warranty. You can call Asus M-F, EST 8:00AM-5: PM.
1-812-282-2787. Not sure you have this number in you're manual. Chances are Asus will send you a new bios. Or you can buy a new bios for $5.00 not including S/H. From Asus online store. Click on this link. http://estore.asus.com/shop/

If I can be of more service, just post back & let me know how thing go.

Mike

SOURCE: memory problem

The ASUS web site shows only two ram slots on the motherboard. Sounds as if the booklet has a misprint. Specifications on the web site list memory as: Dual Channel Memory Architecture
2 x 184-pin DIMM Sockets support max. 2GB DDR400/333/266 non-ECC, unbuffered DDR SDRAM memory. So, 2GB is max.

Hello, I am the technician that will be assisting you today. My name is Norman-Wynne Damstra.

Welcome to Fixya, Tracey Laidler.

Yes you are quite correct BSOD or Blue Screen Of Death is normally due to a memory fault. However drivers are as big a culprit, especially seeing as though you have changed memory modules and processor.

Install all the drivers for this mainboard.
Also enter the BIOS/CMOS by tapping the Delete key during first powering on the computer.
Once in the BIOS/CMOS select the option to load defaults.
Check if that works.

If not then take it a step further by clearing the BIOS/CMOS by removing the silver button cell from the mainboard for 10seconds before reinstalling it in the correct orientation.

Take care!
Norman-Wynne Damstra

Two short double beeps


WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL.


Only work inside the computer case when the power has been switched off and disconnected. Never open the power source.


Some of the below steps recommend removing physical parts within the computer. While in the computer it is highly recommend that you be aware of ESD and its potential hazards


If you've recently added or tried to add additional memory to the computer and have started getting these beeps.


Remove all new memory you've added to the computer.

If the computer works fine after removing the new memory you're encountering either an incompatibility or defective new memory.


Sometimes when the computer is moved or over time a memory stick can become loose causing the computer to be unable to read the memory or get errors as it's reading it.


Try fixing this issue by opening the computer removing each of the memory sticks you have in the computer cleaning the gold coloured tabs with alcohol and then placing them back into the computer.


Remove the memory modules from their slots.

Take the opportunity to clean the slots on the motherboards and the memory module connectors.


Use compressed air to blow dust away and clean contacts with a soft cloth.

Do not use a metallic vacuum cleaner if it touches any component it may create a short and cause damage to the motherboard or other components.


Do not use solvent that may attract dust and never poke things like cotton buds in to slots. lightly rub an alcohol on a cloth not to hard let the alcohol do the work on the copper gold or silver tabs and r


Allow the pins to dry. They will air dry in a matter of minutes


If reseating the memory did not resolve the issue try swapping the location of the memory. If you have only one stick of memory in the computer try moving it to another slot and then boot the computer.



If you have more than one stick of memory try removing all but one stick of memory and boot the computer.


If this does not resolve the issue try removing that stick of memory and try one of the other sticks of memory


If you have access to another computer that uses the same memory, try using its known good memory in your computer.


If another computers memory works you know that you have bad memory. If another computers memory does not work and it is compatible with your computer unfortunately your


Motherboard or the slots on the motherboard are defective causing it to be unable to properly read the memory, which means the motherboard will have to be replaced.


hope this helps
