S5520SC MB. Two (2) years ago I built this computer for digital photography. Editing and printing. XP 64 Bit OS. I used the S5520SC MB and installed just 8GB memory. Dual XEON processors. This month, January 2012 I installed 8GB more. All the memory chips are the same.
The computer, and of course the MB, have functioned perfectly except it is slow loading. Using PhotoShop Elements 7.
But the BIOS and sysytem information shows just 8GB. Some discussions with others have me believing I need to update the BIOS but the avaiable downloads from Intel are confusing to me.
Board pn E30682-303
Serial Number QSHV92800089
Crucial Memory (4 each) 2GB 240-PIN DIMM 256MX64
DDR3PC# - 10600 UNBUFF
Any guidance/input would be appreciated.
If the BIOS and the OS both show only 8GB when you have 16GB installed, I would first check to make sure the memory is on the tested list at
BIOS 60 is the latest, but that very rarely changes this type of symptom.
How did you populate the DIMMs? Is memory mirror enabled in BIOS? What's the status of each memory slot in BIOS?
