Run their diagnostics. –mfinni Dec 22 '12 at 21:39 the machine is a Dell Poweredge 2850. The initial memory count on some systems may indicate 1MB less than expected. The user must manually open Event Viewer to view errors. Reseat the memory modules firmly in their slots to ensure a firm and proper connection. have a peek here

What is Uncorrectable Memory Error? Seeing as it's very consistent in a timely matter it has me skeptical. –Oxymoron Dec 22 '12 at 20:27 Also, memtest isn't showing any issues with the DIMM. –Oxymoron Hsiao showed that an alternative matrix with odd weight columns provides SEC-DED capability with less hardware area and shorter delay than traditional Hamming SEC-DED codes. In registered memory, the registers provide a controlled delay in communication with the chipset.

Correctable errors can be detected and corrected if the chipset and DIMM support this functionality. Most non-ECC memory cannot detect errors although some non-ECC memory with parity support allows detection but not correction. H. Uncorrectable memory errors can typically be isolated down to a failed Bank of DIMMs, rather than the DIMM itself.

Only DDR2 800 Mhz, 667Mhz, and 533Mhz DIMMs are supported. Check This Out I tried taking just that one chip out and moving the last one in its place, but the system barked at me about having mismatched pairs so it disabled my other
Disconnect the AC power cords from the server. The DIMM CL/T is mismatched. Therefore if you want to go back to 2Gb you will need to check either the DIMM or the MB connection and with there being only 6 memory slots on the
Many current microprocessor memory controllers, including almost all AMD 64-bit offerings, support ECC, but many motherboards and in particular those using low-end chipsets do not. An ECC-capable memory controller can In addition, ProLiant servers with Advanced ECC support can detect and correct some multi-bit errors. If you are getting "DIMM slot disabled" message, or a known good DIMM is not seen in a certain slot, make sure that the slot is enabled in the BIOS program The latter is preferred because its hardware is faster than Hamming error correction hardware. Space satellite systems often use TMR, although satellite RAM usually uses Hamming error correction. Many early implementations
DIMM Fault LEDs When you press the Press to See Fault button on the motherboard or the mezzanine board, LEDs next to the DIMMs flash to indicate that the system has p. 2 and p. 4. ^ Chris Wilkerson; Alaa R.

Although hard correctable memory errors are corrected by the system and will not result in system downtime or data corruption, but still they indicate a problem with the hardware. This LED is there because you cannot see the motherboard LEDs when the mezzanine board is present. Use the command: fmdump -eV to view ECC errors Linux: The HERD utility can be used to manage DIMM errors in Linux. It includes the following sections: DIMM Population Rules Supported DIMM Configurations DIMM Replacement Policy How DIMM Errors Are Handled by the System Isolating and Correcting DIMM ECC Errors DIMM Population Rules
Memory used in desktop computers is neither, for economy. Chipkill provides protection for memory similar to RAID protection for disks. Some DRAM chips include "internal" on-chip error correction circuits, which allow systems with non-ECC memory controllers to still gain most of the benefits of ECC memory. In some systems, a similar The memory sockets are colored black or white to indicate which slots are paired by matching colors.
I actually ended up getting dell to replace the whole server and it was fine.
