i checked the pins they look ok, and i have a dimm in C1.
It says Failure when i look in the Biod and Windows 7 is only recognizing 40GB Ram.
I have the same problem with my S5520HCR.
Is there any way to fix it?
Generally this kind of trouble happens when you have very high RAM and your OS is either Windows Vista or Windows 7. I also faced the same problem till the last month. Then I changed my OS to linux and now everything's fine So i suggest you to do the same. If it doesn't work I'll immediately dive you another alternative......
Nitish, the problem is that memory can not be found even in BIOS.
I have the following records in BIOS:
A1 Slot Installed
A2 Slot Not installed
B1 Slot Installed
B2 Slot Not installed
C1 Slot Failure <- !!!
C2 Slot Not installed
Moreover, C1 Slot led lights orange light on motherboard.
1) make sure you are running the most current BIOS code posted for your board.
There have been some code updates to the Memory Reference Code in the BIOS for some DIMMs which did not configure correctly,
2) Check the CPU socket pins.
The DIMM plugs into the DIMM connector and runs directly to the CPU socket which contains the CPU. Not a lot in this path that can go wrong in shipping (all DIMM slots are tested to have worked in the factory)
3) Swap the failed DIMM to another DIMM slot and see if the failure stays with the SLOT or follows the DIMM.
If it follows the DIMM, the DIMM is bad.
4) Swap the Processors (assuming you have 2)
If the DIMM marked fail (C1) switches to (F1) Your processor is bad. ( I have never see a processor fail this way, but it is a possiability)
If C1 is still reporting Bad, you CPU socket Pins, mmother board or DIMM socket pins are bad.
