Obviously, good quality running error-free

For my audio and image editing programs I needed for my commercial PC urgently a memory upgrade. I have therefore the above RAM for memory expansion already my 8 year old - but then very expensive DELL Dimension 9200 RAID office computer - bought, and was initially very skeptical about whether the "upgrade" will work from 2 to 4 GB. In the first experiment the bios reporting problems then I have exchanged with Bank A Bank B - and it worked without any problems now. Meanwhile, the computer has been running for two months (every day more than 8 hours) without any error message but with significantly better performance! And thanks to a small additional program (not included) I can even despite 32bit system now use the full 4GB of memory running Windows 8 even. Therefore, I forgive like 5 star.
