Computer is reporting me a faulty ram and i don't know why. I checked compatibility with crucial official ram modules for optiplex and they are pretty much the same. Please help me. Yes i have updated the BIOS i also tried older BIOS versions i tried all combinations of DIMM's on the motherboard. I realy don't know where i did my mistake.

SNPP223CC/2G is the Dell Specific Part number for ram that WILL WORK.
Many shops are clueless as to what IS or IS NOT low Density.

Dell computers are fussy about ram. See how this recommended Crucial memory compares with the ram you have--

Always best to match the memory chips and not mix ram from diff suppliers.

Crucial has both 1.35v and 1.5v versions of the ram.
SNPP382HC/4G

Ram that supports either voltage is common.
The issue is LOW Density INTEL compatible Ram.

So i have to buy low density ram ? correct?
Because i do not live in US i have to buy it from local HW store. So i go in there and say that i want low density intel compatible ram, right?
