How to Determine which DIMM to Replace Given Kernel Panic Report

Question

I have a dual cpu, mid-2010 Mac Pro with 32GB of Kingston RAM (8 4gb modules). Once a week or so, it suffers a kernel panic that appears to be caused by a RAM problem. Here is a typical one:

They all point to DIMM 0, Channel 1, and indicate addresses like 0x00000004xxxxxxxx. My question is: If I am interested in replacing the suspect DIMM, which one is it?
In the User Guide, it indicates I have 8 memory slots, organized in two chunks, each chunk adjacent to a cpu. The diagram says that Slots 1-4 are adjacent to one CPU, and Slots 5-8 are adjacent to the other. I, of course, filled all of them myself. System Profiler tells me about DIMMs 1-8. The kernel panic report seems to tell me that DIMM 0 is to blame, perhaps DIMM 0 in Channel 1. Here is a representation of the slot layout in the User Guide:
slot 5        CPU
slot 6        slot 4
slot 7        slot 3
slot 8        slot 2
CPU         slot 1
latch         latch
where the bottom of the diagram is toward the side of the tray that has the latches that release the tray. The form of answer I'd like to see is something like: Replace the DIMM in Slot 1. Or perhaps: Replace the DIMMs in slot 1 and slot 5.

Answer 1

Perhaps I wasn't clear. The Genius *did* look it up - it took him about 5 actual minutes - and he said that all he could tell was that it was a memory error of some sort. I was asking him specifically what the 4 and 66 meant as well as the hex number. And with a ton of google I was unable find much about it.
I know quite a lot about how to eventually find the bad DIMM, if there is one. The machine in question is used heavily for Photoshop, InDesign, audio editing, some video editing, and programming, and if the memory failures (or memory controller errors) were more frequent, I would engage in classical isolation techniques - and I probably will have to. It simply seemed to me that the information I need is in the kernel panic logs.
