[Lugstuff] DIMM to Capacitor

They are probably electrolytic "can" capacitors related to a local voltage
regulator.  Look for polarity (+/-) on the capacitors and for nearby 3 or 5 leg
ICs.  If they are not surface mounted, you may be able to de-solder and pull
them out or snip them off and hand solder replace them with similar capacitors.

Subject: [Lugstuff] DIMM to Capacitor


Hardware question, I have a 4 DIMM motherboard, which I have used slots 1 & 2
since purchased.  


Recently, I've been getting a parity error.  Over the weekend, I cleaned the
computer and reset the memory, and notice two ballooned capacitors near the DIMM


Two additional and similarly placed and sized capacitors are not ballooned.  I
swapped the ram to slots 3 & 4 and so far all is well.  


Does any one know if there is a one to one relationship to the DIMM slots or
DIMM pairs, and capacitors?  


This is a Dell 0CJ774 motherboard in a 380 Precision WorkStation.  The manual
says to install RAM in pairs using slots 1 & 2, then 3 & 4. 


Dell Support was useless.


Thanks, Bill
