My ddr dimm's184 pins & slot must be cleaned every week

The dust is from your own air. What the hell are you breathing?

Greetings TE Chea..

While dust can be a real issue in personal computing and preventative maintenance should periodically be performed, you shouldn't have to go to such extremes of alcohol and cotton swabs on DIMM sockets! Of course, this is also dependent on the environment that you PC is in which, isn't stated here.

While dissimilar metals that are in contact can and often do corrode over time resulting in a high impedance electrical connection, with the sheer pressure of the contacts of the DIMM socket upon the DIMMs, electrical conductivity shouldn't be an issue. It certainly is possible to have a socket that has simply worn out. Especially if that socket has been excessively used for removing and replacing memory modules (DIMMs). However, again, for the ordinary PC user, this should be an issue. It should also be stated that it is also possible to have a defective socket or one that is extremely cheap in construction quality that could contribute to premature failure.

A couple of suggestions:

1. If you're in a inside office, home environment and the case can be situated to a higher level (off the floor) do so. It's amazing how much dust can be accumulated while PCs actually sit on the floor. If it's even possible to put the PC up on top of the desk, try this for a while to see the difference.

1. As you're doing, continue to periodically clean the air filters and check the fans for proper operation. As you know this will continue to provide a bit cleaner air to the inside components.

2. Obtain a white film eraser. Reference,

   and notice the model

1186. More specifically, I have been using this style of eraser for years on all contacts, gold plated or otherwise. The reason is it isn't abrasive, it will clean off all oils, dirt & corrosion from fingerprints or oxidation. Thus, once the shavings are brushed away, you're left with a shiny series of contacts that will maintain electrical contact for a substantial period of time.

Try cleaning the contacts with a white film eraser to the DIMM that you're using, brushed off the shavings and inspected that the socket in which it is going is mechanically sound. There should be no further issues. IF there are within a short period of time, the problem is probably NOT mechanical but an intermittent (possibly heat related) electrical issue. A simple way to confirm that is to plug in another DIMM in its place for a couple of weeks and see if the problem returns. If not, your previous DIMM has electrical issues. Of course there are also memory tests, mem86 for example, that can be run continuously to determine memory failures. Eliminating as many possible causes, as much as possible, then, ultimately, isolating the cause is the answer to determining the real problem here.

| What the hell are you breathing? Dust, I need to dig out dust caught by my nose's wax, every day. Here in msia, govnmnt allows open burning, air is not as clean as in e.g. Sydney ( australia ), even when no smoke comes fr Indonesia.

I live in the same country like you but never had the problem like yours with all the PCs I ownwd. If my PC developes such a problem I would either 1) change the memory slot socket 2) change the dimm in question or 3) change the Main board to solve the problem completely.

I once found that the CPU had collected so much dust that the CPU stoped functioning after 1 or 2 hours. FYI I didnt install any air filter in the PSU or CPU fans.

Unless the dust is adhesive, it can be kept from accumulating by rotating your computer so the sockets face DOWN. But really, your CD drive and other parts can't tolerate much dust; have you considered an environmental filter (like adding a HEPA or electrostatic filter to a forced-air building heating system)?

Clearly your casing's air intake could use better particle filters, and there are some sticky spray-on coatings that could enhance the 'sponge'.
