Thanks for the responses, guys! This hasn’t been much of a day!
Jim, I would love to try new memory modules in my mobo, but I’m 60 miles from the nearest store and they wouldn’t have anything that would be approved for my mobo.
In my mobo manual, I don’t see any reference as to what slots relate to what addresses. Actually I found the 12.2-64 DVD memory test is pretty easy to debug with.
Robin, I did try your approach switching modules, but the results as I unterpret them suggest two conclusions. Let me first share my conclusions. If you are still with me afterward, i’ll give you my preliminary observations.
Either the memory test 7 is invalid for my hw, or the memory modules are not compatible with my mobo.
While I type this with my 12.1 Pentium3 backup system, my new pride and joy is crunching out the 12.2-64 DVD memory test 8. There’s no errors yet, like tests 1-6. I think there are only 9 or 10 tests total in this suite, but maybe there’s more.
Test 7 fails solidly from the first pass every four addresses starting with 0x00008100000 then 4 then 8, etc. The “good data” is random like 0xf5ab9d7fa. The “bad data” for this pattern is f-f. Other addresses and patterns give 0-0.
The 0s Vs fs may have to do with swapping modules, one module Vs two. Either of the modules fail the same way in the same memory slot and both also fail the same addresses when both are plugged in together.
It’s like test 7 fell off an address cliff! I would dearly love to know that this test passes on similar hw!
Of course, I don’t know what test is on my DVD, so even if someone was willing to verify this for me, what could I tell them to run?
If you’re sill with me, the second point is unqualified mobo modules. My barebones was a kind of kit that the seller assembled and did a smoke test on. They have been easy to work with so far, but that may be coming to an end!
The memory modules that came assembled into the mobo are 8GB Super-Talent DDR3 -1600 Micron W1600UB8GM 8GI512x8.
The mobo qualified list shows 6GB Super-Talent DDR3 -1600 Micron WA160UX6G9 6GB 3x2GB. The date on the mobo manual is 9-12.
So when I call my seller tomorrow he’s going to tell me his part is qualified now and test 7 is broke.
What are the chances that my mobo is addressing the 2GB of memory that the qualified memory wouldn’t have when test 7 runs? And farther that test 7 is the only test in the suite that addresses this area?
To me the failure is catastrophic whether the test or the hw.
It seems I have a hw problem because of the virtualbox behavior. The computer thinks it has 16GB of memory. Any more suggestions? Heboland.
