Symptoms of a bad RAM slot?

post #1 of 3
Thread Starter 
Can a bad RAM slot cause a BSOD every few weeks or every month or would it cause far more frequent BSODs?

It could be. I have alway's arrived at diagnosing a bad slot(PCI-E, CPU socket, RAM) by replacing the suspect hardware(in your case RAM) with some of known working quality, Such as from a back up rig, personal stock, or borrow from a friend.

Defective motherboards and CPU's are the most difficult for a home user to trouble shoot.

There's no way to know.


Run a self-booting memory diagnostic, like MemTest86 ver. 3.5b or MemTest886 ver. 4.2, while wiggling each DIMM slightly. If the diagnostic keeps running and doesn't report errors, the slots are probably fine.

Are you using memory of questionable quality, that is, does it have heatsinks, are the chips not identifiable by actual manufacturer (Samsung, Micron, Hynix, etc.) or are the chips overclocked?

Look at the slot with a magnifier and bright light for things like slightly bent contacts, lint, or discoloration. Straighten contacts very carefully with a dental pick or very thin needle nose pliers (preferrably with smooth jaws). Lint can usually be blown out. Discoloration can be cleaned with contact cleaner, like De-oxit, or alcohol, but sometimes you have to apply it to a piece of solid cardboard the thickness of a DIMM and insert and remove it several times.
