If you populate the B DIMM slots their memory will show up in csrows 0 and 1. Posted by MSslave on 20 Oct 2004 15:52 I'm having the same error on a Poweredge 6450. Error detection and correction depends on an expectation of the kinds of errors that occur. Check the POST error log for error message 289. have a peek here
But for reasons unknown, with the identical motherboard and SuSE Enterprise (SLES11SP3, kernel 3.0.101-0.31) the EDAC sysfs /sys/devices/system/edac/mc directory is empty. Back to top How do I know which RAM module is failing? This makes identifying the DRAM address and correspondingly, the failing module, much more difficult. The DIMM slots are paired and the DIMMs must be installed in pairs (0-1, 2-3, 4-5, and 6-7). over here
For systems where the address decoding scheme is known, MemTest86 provides several configuration file parameters to aid users in determining the faulty module that corresponds to the memory address: ADDR2CHBITS=12,9,7 ADDR2SLBITS=3,4 In unbuffered memory, the chipset controller deals directly with the memory. p. 2. ^ Nathan N. Please have the FRU/CRU numbers of the defective DIMM(s) available for the support technician to expedite warranty replacement.
Turn off the system and attached peripherals, and disconnect the system from the electrical outlet. You may also choose to replace the RAM with modules that have been known to pass the Hammer Test. Take a look at the EDAC messages for MC3 again: EDAC amd64: ECC is enabled by BIOS.
EDAC amd64: F10h detected (node 3).
EDAC MC: DCT0 chip selects:
You get the same if dividing the CE error address by the size of a DIMM. 0x24bcfff3d0 = 157,789,713,360 bytes = 146.95 GB 146.95 GB / 16 GB = 9.18 Reply
This is found under the Advanced Setup/Memory Settings menu: Boot the system, and press F1 to get into BIOS. How does MemTest86 report ECC errors? All rights reserved. http://www.dslreports.com/forum/r25455469-ECC-Single-bit-fault You can use the Poweredge Diags tool that you can get from the Dell support site or search for a file called mpdiags.exe 0 Message Author Comment by:jamessa2006-02-28 I am
MemTest86 reported the memory address of the failure. Note: When you handle Electrostatic Discharge-Sensitive devices (ESD) such as memory, take precautions to avoid damage from static electricity. overclocking). EDAC amd64: F10h detected (node 3).
BIOS displays smaller memory size than installed Hynix DIMMs may cause system boot failures Empty DIMM slots disabled by default (xSeries 305) Memory is not all seen by the operating system Visually inspect the DIMM slot for physical damage. Having to invert the logic for the rows is really annoying. However, the Motherboard Fault LED lights to indicate that there is a problem on the motherboard (only while AC power is still connected).

DVMT has the ability to dynamically allocate additional memory whenever it is required, and conversely, release it when it is no longer needed.
Here is the log I got: Mon Feb 27 13:07:01 2006 ECC Single Bit Fault detected - Bank 2, DIMM A Mon Feb 27 10:09:02 2006 Bezel Intrusion sensor return The original IBM PC and all PCs until the early 1990s used parity checking. Later ones mostly did not. I understand that swapping out DIMM A in Bank 1 would probably fix the issue.

Lay summary – ZDNet. ^ "A Memory Soft Error Measurement on Production Systems". ^ Li, Huang; Shen, Chu (2010). ""A Realistic Evaluation of Memory Hardware Errors and Software System Susceptibility". we have an error at 0x24bcfff3d0. This means that memory of one 4GB DIMM in slot 1A and one 4GB DIMM in slot 2A show up in two rows and two channels.
Most motherboard vendors release a list of known compatible RAM models that have been tested to work with your motherboard. During reboot, the BIOS checks the Machine Check registers and determines that the previous reboot was due to an UCE, then reports this in POST after the memtest stage: A Hypertransport Promoted by Experts Exchange Engage with tech pros in our community with native advertising, as a Vendor Expert, and more. If the DIMM was disabled by a system-management interrupt (SMI), replace the DIMM.
b. Back to top How do I fix the memory errors? SDRAM memory in a server can be either registered or unbuffered. this contact form ECC memory is fault tolerant and single bit errors can be corrected without shutting down the server.
Poweredge 1750 A08 Join Sign in ECC Single Bit Fault detected.
