PERC 5 DIMM

Are the following interchangeable? We had a PowerEdge 2950 giving "multibit ECC errors were detected on the controller. DIMM on the controller needs replacement. If you continue data corruption can occur. Press 'X' to continue or else power off the system and replace the DIMM module and reboot. If you have replaced the DIMM please press 'X' to continue.

We ordered 6R829 but received DG025 instead.

Found this description of them on the web:

DG025 PERC 5E DIMM
6R829 PERC 5I DIMM

Could anything else cause the problem? I'm tempted to replace the whole PERC5i plus DIMM plus battery.

I would suggest you replace the whole PERC controller rather than using a separate DIMM...

Yes, the controller could be the cause ... you never stated whether or not you replaced the DIMM with the one you received.  The part number doesn't matter ... they simply indicate different manufacturers/locations/runs/etc.

Yes, we replaced it with the one we received, it was about 3 months ago and only just failed again.

That's why I suggest replacing the controller...

I don't tend to change memory because it could be something else within rather than just memory...

What is the firmware version you are running?  The firmware holds the algorithms for managing the batteries.  Still could be a bad controller, but it may just need the firmware updated.

I'm guessing you meant 5.2.2.0072, which is the latest.  Not leaving out the possibility of another DIMM simply failing, it is unusual for the DIMM to need replacing very often, so I would be suspicious of the controller at this point.

Thanks chaps. Looking at the prices the DIMM is £28 and the controller including DIMM £40 so maybe we should have got the whole thing first time rather than save £12.
