Need some clarification on suitable ram for DELL poweredge SC440 Tags: RAM Dell Networking Last response: February 3, 2011 12:37 AM in Networking Share scampy_008 November 1, 2010 4:56:59 PM Heres the problems. A client of mine has one of these which I beilieve is a basic one socket server tower. He currently has 2GBs of ram installed and he wants to upgrade to 4GBs. His current configuration of ram is 4 x 512mb 1Rx8 PC2-5300E-555-12, Model Number Hynix HYMP564U72CP8-Y5 I sent him some 4 X 1GB 1Rx4 PC2-5300P-555-12, Model Number Hynix HYMP512P72CP4-Y5 Result, No Post no Boot. Ive tried to do some research into this but the information is conflicting. According to the spec sheet from dell this thing can take "Four ECC DDR-2 533/667 SDRAM DIMM sockets for up to 4 GB of memory" As far as I am aware this is "ECC" ram. I am missing something here, is the difference between PC2-5000E and PC2-5300P?? According to my research I did find something about registered and unregisted. I thought all ECC ram was in fact registered. Can I have some clarification or advise on the issue please!!!

Get the answer Emerald November 1, 2010 7:14:58 PM NO not all ECC is Registered. The Dell wants ECC Unbuffered. the memory you are trying to use is Registered and therefore does not seem to work. scampy_008 February 3, 2011 12:37:57 AM Ok Guys forgot to reply. I know theres a bif difference in ECC, 2 type ECC Registered and ECC unbuffered. they are not compatible and interchangable with one another. Also most systems that will accept ECC Unbuffered Ram usually 95% of the time accept NON ECC ram, which is easier to find and much cheaper then ECC unbuffered definately in terms of DDR1 Thanks!
