Yes, the controller could be the cause ... you never stated whether or not you replaced the DIMM with the one you received. &nbsp;The part number doesn't matter ... they simply indicate different manufacturers/locations/ru<wbr />ns/etc.

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

<div>
That's why I suggest replacing the controller...<br />
<br />
I don't tend to change memory because it could be something else within rather than just memory...

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

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.

Are the following interchangeable? We had a PowerEdge 2950 giving &quot;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.<br />
<br />
We ordered 6R829 but received DG025 instead.<br />
<br />
Found this description of them on the web:<br />
<br />
DG025 PERC 5E DIMM<br />
6R829 PERC 5I DIMM<br />
<br />
Could anything else cause the problem? I'm tempted to replace the whole PERC5i plus DIMM plus battery.

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.
