Intel S3420GPRX RAM issues - system not booting

Hi all.

I'm trying to set up a Server system for a local charity. We recently bought an Intel SR1695GPRX2ACNA Barebone System, which includes an Intel Server Board S3420GPRX motherboard.

To go with it, we bought an Intel Xeon X3470 SLBJH - 2.93ghz 8M Cache CPU.


We then bought the following RAM: 4 X Samsung M393B5170DZ1-CF8 4Gb RDIMM PC3-8500

(This RAM is listed as compatible with the motherboard according to an online PDF document I found.)


The system will not boot-up with this RAM in place. I get the 3 beeps errors, which according to the manual is a RAM issue. The seller of the RAM sent us a different model of RAM (again, Samsung but a different model number, I never noted which) but the outcome was exactly the same. 3 beeps per RAM module, regardless of which slot the RAM is placed in.


The seller of the motherboard has just issued a replacement but guess what? The same issue again - 3 beeps on booting the system and it doesn't go any further. I'm thinking now of maybe trying UDIMM RAM but I'm struggling with this one. :banghead:



Any help or advice on this greatly appreciated.
