I have just purchased a new S3420GPV but it dosen't boot after integrating the parts:
CPU: X3440 (tested list)
Memory: KVR1333D3D4R9S/4G x 2, ECC Registered Dual (tested list)
Harddisk: ST31000524NS x 2 (tested list)
Power Supply: Cooler Master GX-550W, ATX v2.31 with CPU 4+4 Pin
I get no beep sound as the server board has no buzzer, but I have the following Diagnostic LED POST Code cycling:
0xB8 OXOO OXXX
0xBA OXOO OXOX
0xEB OOOX OXOO
I have tried removing and replacing CPU and the memory with different population: A1/B1, A1, B1, A2/B2, .... many many times!!!
Two things to check:
1. Support of registered memory on S3420GPV was added in BIOS 43. If your board has BIOS earlier than 43, you may need to boot the system with unbuffered memory and update the BIOS first.
2. Note the last letter "i" for Kingston DIMMs in the memory list - it indicates validated on Intel boards. We have seen issues with non-"i" DIMMs on Intel motherboards, although memory specs might be the same.
From "Intel Server Board S3420GP Technical Product Specification"
S3420GP has the following limitations:
- 256 Mb technology, x4 DRAM on UDIMM, and quad rank UDIMM are NOT supported
- 256 Mb/512 Mb technology, x4 and x16 DRAMs on RDIMM are NOT supported
4GB 512M x 72-Bit PC3-10600 CL9 Registered w/Parity 240-Pin DIMM
This document describes ValueRAM's 512M x 72-bit 4GB (4096MB) DDR3-1333 CL9 SDRAM (Synchronous DRAM) registered w/parity, dual-rank memory module, based on thirty-six 256M x 4-bit DDR3-1333 FBGA components.
I think this is the problem: the S3420GP(V) does not support x4 DIMM's.
I encountered the same problem, difference being the memory model used by me (KVR1066D3S4R7S/2GI 2GB 256M x 72-Bit PC3-8500 CL7 Registered w/Parity 240-Pin DIMM - based on eighteen 256M x 4-bit DDR3-1066 FBGA components - also in the tested list).
