further help diagnosing ereport.cpu.intel.quickpath.mem_ce

I am still trying to diagnose the issues with these two systems (dual
Intel 5520/supermicro X8DT3). When I have two PC3-8500 ECC RDIMMs
populated per channel (6, 4G RDIMMs/socket), I see the following fmdump
-e reports reliably every 10 seconds:

Nov 24 2009 09:34:40.410002797 ereport.cpu.intel.quickpath.mem_ce
Nov 24 2009 09:34:40.410013341 ereport.cpu.intel.quickpath.mem_ce
Nov 24 2009 09:34:40.410025191 ereport.cpu.intel.quickpath.mem_ce
Nov 24 2009 09:34:40.410060807 ereport.cpu.intel.quickpath.mem_ce
Nov 24 2009 09:34:40.410071957 ereport.cpu.intel.quickpath.mem_ce
Nov 24 2009 09:34:40.410134184 ereport.cpu.intel.quickpath.mem_ce

(I've included the details of these reports at the bottom of this email.)

While the reports seem to indicate that there is a problem on the second
row RDIMMs, swapping the memory sticks around yields the same problem.
In fact, even when I have only on RDIMM in each channel the machine will
experience occassional ereports on memory.

I have tried forcing the BIOS to run the memory @ DDR-1066 and DDR-800
and still have the same behavior, so it would seem to not be related to
memory quality. The memory modules appear to be reasonable quality stuff:

Hynix

I have tried opensolaris b127, b126, 2009.06, and S10U8, all with
variations of these same symptoms. I am really hoping that someone can
either give some guidance on further diagnosing what is going on, or can
point me to which mailing list on which I should follow-up.

Here is the detailed fmdump ereport information:

I think it is a hardware issue you are looking at and not software.
You are seeing significant correctable memory errors I would guess that
the dimms are not compatible with the motherboard, perhaps requiring too
much power.

After a little more digging, now I am really confused about what is
going on. It turns out the the exact memory modules are Hynix
HMT151R7BFR4C-G7, which are on the verified list for this particular
motherboard:

http://www.supermicro.com/support/resources/memory/display.cfm?sz=4.0&mspd=1.066&mtyp=32&id=144D7111B7126A9A938F3113403B15D6

So now I am left wandering if there is some subtle incompatibility with
the chipset (Intel® 5520 (Tylersburg)) and current Solaris/Opensolaris.

Is there anything someone can suggest to determine this with certainty?
Or are the ereports "absolute" in the sense that the memory is simply
having these errors?

Post by Paul Fisher
I am still trying to diagnose the issues with these two systems (dual
Intel 5520/supermicro X8DT3). When I have two PC3-8500 ECC RDIMMs
populated per channel (6, 4G RDIMMs/socket), I see the following fmdump
Nov 24 2009 09:34:40.410002797 ereport.cpu.intel.quickpath.mem_ce
Nov 24 2009 09:34:40.410013341 ereport.cpu.intel.quickpath.mem_ce
Nov 24 2009 09:34:40.410025191 ereport.cpu.intel.quickpath.mem_ce
Nov 24 2009 09:34:40.410060807 ereport.cpu.intel.quickpath.mem_ce
Nov 24 2009 09:34:40.410071957 ereport.cpu.intel.quickpath.mem_ce
Nov 24 2009 09:34:40.410134184 ereport.cpu.intel.quickpath.mem_ce
(I've included the details of these reports at the bottom of this email.)
While the reports seem to indicate that there is a problem on the second
row RDIMMs, swapping the memory sticks around yields the same problem.
In fact, even when I have only on RDIMM in each channel the machine will
experience occassional ereports on memory.
and still have the same behavior, so it would seem to not be related to
Hynix
I have tried opensolaris b127, b126, 2009.06, and S10U8, all with
variations of these same symptoms. I am really hoping that someone can
either give some guidance on further diagnosing what is going on, or can
point me to which mailing list on which I should follow-up.

After a little more digging, now I am really confused about what is
going on. It turns out the the exact memory modules are Hynix
HMT151R7BFR4C-G7, which are on the verified list for this particular
http://www.supermicro.com/support/resources/memory/display.cfm?sz=4.0&mspd=1.066&mtyp=32&id=144D7111B7126A9A938F3113403B15D6
So now I am left wandering if there is some subtle incompatibility
with the chipset (Intel® 5520 (Tylersburg)) and current
Solaris/Opensolaris.
Is there anything someone can suggest to determine this with
certainty? Or are the ereports "absolute" in the sense that the
memory is simply having these errors?

It does look like the memory is really having these errors. The
syndrome, physaddr, ecc_counter etc are all constantly changing, so it
doesn't seem like they are just "stuck" values or anything.

From the ecc_counters you do seem to be getting a large number of
errors, more that a few every ten seconds (we only poll the ce counter
registers every few seconds so there could be far more than we are
reporting).

I have seen problems like this before where there is something like a
solder problem on the socket causing a short. This gets a CE almost
every otrher access, but the ECC mechanism prevents this from turning
into a UE.
