we have a problem with a S5500bc board and Kingston memory. We Receive 3 long beebs immediately after powering on the system. Acutally we tested two different types of Memory from Kingston.
KVR 1066D3Q8R7S/4G 4GB PC3 - 8500 Parity REG CL7 240 and
On the POST Code Diagnostic LED Decoder area we receive the error OOOX OXXX. The error message says: No Usable Memory Error: No Memory in the system, or SPD bad so no memory could be detected.
The CPU in the system is a Xeon E5640.
Please help us to solve the problem.
Hmm, You may want to give it a try with just 1 DIMM installed. Then update the BIOS (and the rest of the code stack)
BIOS contains the Memory Reference Code and some DIMMS need newer code to correctly be configured.
