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.
thank you for you answer. We checked it with one DIMM - but its also beeping with just one module installed. At the moment we are trying to find some older DIMM modules.
