Thank you Chris, Bret, and Heiko for your replies, both on- and off-list. |

Your replies all look like good suggestions and I'm going to try them, but |
4 |
first, I have to ask one other thing. |
5 |
|
6 |
As I said earlier in this thread, I found zero errors in an 8 hour |
7 |
exhaustive memory test (using the Dell-provided Utility Partition tests) |
8 |
running 15-16 loops, 4 different tests, and found zero errors from a |
9 |
complete hardware test (also from the Utility Partition). |
10 |
|
11 |
But just on a lark, I decided to try memtest86 3.0 and 3.1a as well, and |
12 |
both are turning up errors all over the place. I'm skeptical that |
13 |
memtest86 is giving me accurate information because (a) it's finding so |
14 |
many, (b) I can't seem to get it to turn on ECC mode (yet the Dell |
15 |
utilities did test this, and the CMOS reports that it is ECC memory), (c) |
16 |
it runs for only 10 seconds or so and begins finding errors, and (d) it |
17 |
locks up after about 2-5 minutes. Last time I ran it, the error count |
18 |
was up to 109 after 5 minutes and then it locked up. |

Any thoughts on this? |
21 |
|
22 |
Is this bad memory (in spite of the Dell tests all turning up flawless) or |
23 |
is memtest86 getting something wrong (like amount of installed memory to |
24 |
test)? Any way to tell for sure? I've looked at the docs for memtest86 |
25 |
and they talk about the possibility of memtest86 incorrectly determining |
26 |
the amount of memory to test and that seems likely in my case. The first |
27 |
10 or so errors are all at the same address (0003fffdc80) 1023.8MB, then |
28 |
there are 4 or so at 64.0MB, then 1 or 2 at 0.6MB, then it locks up. |
29 |
|
30 |
The Dell utilities report testing only up to 1022MB of memory. |
31 |
|
32 |
Is this a case of memtest86 getting the installed memory count wrong? |
33 |
When I look at the CMOS/BIOS settings, the System memory is 1024MB, and |
34 |
that's what the Dell utilities also report initially, but the tests |
35 |
themselves are only being run on the first 1022MB, according to the test |
36 |
reports. |

Thanks. |
