I have a s2600cp2, after a hdd upgrade i seem to have lost half my RAM.
DIMM A1, B1 and DIMM C1-2 DIMM D1-2 indicate failure by 3 long beeps then pause then 3 long beeps again before boot and the LEDs on the corresponding DIMM slots light up.
I have sticks in A1, B1, C1, D1, E1, F1, G1, H1
I have cross-swapped the sticks so the fault follows the Slots not the sticks. I have tried letting the system sit with no power for about 1-2 hours, also tried removing the Cmos battery for about 15 mins.
Hoping anyone can help indicate if the board needs to be replaced or have any other tips to fix the problem.
