From what I read in the TPS at http://www.intel.com/support/motherboards/server/s3420gp/sb/CS-030742.htm , you can put in four 8Gb DIMMs, and they'll run at 800MHz, even if they're 1066MHz natively. The only tested 8Gb memory I see is the Samsung M393B1K73BH1-CF8 at http://serverconfigurator.intel.com/configure-memory.aspx?id=MzQyMSMxLDM0MjkjMQ==&ShowNavigation=false
I bought a S3420GPLC + 4x 4GB Kingston RDIMM - KVR1333D3D4R9S/4G - 4GB PC3 - 10600 Parity REG CL9
When I power on the system I get 3 beeps, according to the documentation this indicates a memory issue.
I also get the 3 beeps when there are no DIMM's installed. I tried different DIMM configurations, 1 DIMM, 2 DIMM's, 1 DIMM on the blue socket... no matter what I tried I always got the 3 beeps and that's it. I also cleared the CMOS but that didn't helped either.
Did I purchased the wrong DIMM's ?
I do no have server replacement components. All I have is an i5 Quad and common 2GB DDR3 DIMM's for desktop boards. Can I place these on the S3420GPLC for testing purpose? Or could this damage the board?
"Three beeps" means the server board doesn't like the memory you chose. Specifically, we see this a lot using Kingston memory without the "I" at the end.
Check http://serverconfigurator.intel.com/configure-memory.aspx?id=MzQwMCMxLDExOTUjMSwzMzY3IzE%3d&ShowNavigation=false for memory that won't give you that error.
