It's possible your RAM is faulty... To test it, read on. This is some information from one of our wonderful Tech Moderators.Click this for a guide to using MemtestClick this to download Memtest
Run it overnight if possible.
With Memtest86 the Report is accumulated on-screen while the test is scanning with various patterns.
A Pass %
(percentage of Test completed) keeps a progress tally of any single test Run.
Each portion of a Test Run is called a "Pass". The term "Pass" is misleading, in that people could think it means "pass" as in a passing score.
But it actually means a "pass" like the full swing of a digital photo copy scanner swinging across the page.
Then below that Pass percentage is the progress of the specific pattern test
Below that is Testing
: which shows the amount of RAM being Tested
Below that is a description of the Test Pattern
being "passed" during that portion of the test.
For instance moving "inversions" "1" and "0", Then 8 bit pattern inversions, then on and on....
In pattern fefefefefe , or 45a2d44d, fffffffed, 00000020, etc
Below that information is the Results Report
Time, - Cached(RAM) - RsvdMem - MemMap - Cache on/off - ECC - Test Pass - - Errors
- Ecc Errs
The critical indicator is the (green) Errors
(on the actual test screen it is not highlighted in green and I am just using the highlight to point you at the correct item)
We won't often see any results in the ECC Errs section since this is for ECC RAM which is most often used in Servers requiring Error Correction Chip RAM. (ECC RAM stick look the same as non-ecc, but have an additional small chip for error correction) non-ecc = 8x64, ECC = 8x64 plus one small additional chip
" number other than Zero under Errors
constitutes a FAILURE
Ordinarily the number will be a quite LARGE number, but a smaller number (constituting a Random Sequence Error) can be just as deadly to the accurate performance of a machine as a steady failure.
The above information is "just how I have come to understand" MemTest86 results and does not constitute any sort of authoritative wisdom.
MemTest86 has quite a good Readme.txt
that comes with the zipped download and as I recall also provides additional research links. It would be well to read it.
At the very Bottom of the MemTest86 screen is the Navigation Bar
( C ) configuration
(sp) scroll_lock (cr)scroll_unlock
memtest86 - press - ESC
(No need to turn off the machine, it will simply proceed to attempt to boot into Windows)
To configure other information
for viewing - press - C
To get out-of
the "other information" popup, just hit "space bar
Hope this helps.
I was intimidated of MemTest86 the first few times I used it, just like the OP that you have been helping.
