  Memory slot dis-function. Is it dead? 
 Date Written 
Bob Hubbard May 18, 2011, 12:35am EDT Report Abuse
Did a bad thing. Had two memory cards (DDR2-800 2GB)and added two different cards (XP2-6400 4GB). Wouldn't boot up. Took the new boards out and got the steady beep of "no memory". Moved the original cards to the other two slots and all is well.
BUT: Does that mean at least one of the two original slots can no longer be used for additional (correct) memory??

Thanks for any help!

Well, if you only tried one or two times...not necessarily.

The system might not have properly auto-sensed and then set the memory SPD parms, or a BIOS CMOS reset might have been needed to fix a temporary issue, or you might have simply mis-inserted the old modules, etc.

There have been perhaps a dozen times or so when I've had to power-off the computer, remove the AC power for 30 seconds or so, and THEN clear the CMOS and re-boot into BIOS Settings menu...and REPEAT those several steps SEVERAL TIMES IN A ROW to "fix" a glitch encountered when I changed a configuration.

That's happened to me often enough and on different machines, as to convince me to put it in my standard "bag of tricks" for handling "odd" issues that arose after a configuration change.

The exact causes can vary, including such things as inadequately seated RAM module, to a temporarily overheated component, to accidentally "injecting" a low-level electro-static charge into the motherboard (which CAN corrupt the CMOS without causing permanent damage...I've personally tested this in the lab), and more.
