That's not going to make any difference.

Hi Paul,

I'm using that computer now, but it will likely BSOD in an hour or so,
where I don't even know if the Usenet posts will work at that's a ton of
setup in and of itself.

Based on that page, I'd pull two sticks of
RAM out of there, and operate in dual channel mode

Thanks for that suggestion, where I already reseated the four memory
modules, but I have not yet run with reduced memory (which I will do after
I run the tests described below).

Prior to posting I had run the HP memory test (and CPU and MB tests), but
it doesn't hurt to test s'more as I'm gonna remove RAM one by one after
this test, which I document below to benefit the Windows tribal record:
o How to Perform a RAM Check in Windows 10?
https://theitbros.com/ram-memory-check-windows-10/
o C:\Windows\System32\ bcdedit /bootsequence {memdiag} /remove
o Start Run mdsched Check for problems the next time I start my computer

I'll likely run the "extended" test, which is described as:
Basic ¡V MATS+, INVC and SCHCKR
Standard ¡V MATS+, INVC, SCHCKR, LRAND, SCHCKR3, Stride6, WINVC and WMATS+
Extended ¡V MATS+, INVC, SCHCKR, LRAND, SCHCKR3, Stride6, WINVC, WMATS+,
CHCKR4, CHCKR8, Stride6, Stride38, WSCHCKR, WCHCKR3WStride-6 and ERAND

I'm not sure the advantage of disabling the cache but the pass count might
be important to set (0 until stopped, or up to 15 passes).

The results will be saved into
o Start Run eventvwr.msc
o Event Viewer (Local) Windows Logs System (MemoryDiagnostics-Results)

That came out clean with four 4GB memory sticks in their original slots.
"The Windows Memory Diagnostic tested the computer's memory and detected no errors"
(although I'm now stuck with a bottom-right Windows 10 test mode watermark!)

Moving forward, this article suggests additional sets of memory tests:
o How to Test Your Computer¡¦s RAM for Problems
https://www.howtogeek.com/260813/how-to-test-your-computers-ram-for-problems/
"MemTest86 provides both an ISO image you can burn to a CD or DVD and a
USB image you can copy to a USB drive. Just run the .exe file included
with the download and provide a spare USB drive to create a bootable USB
drive. This will erase the contents of the drive!"

Where that reference suggests freeware memory tests using memtest86:
o Boots from a USB flash drive to test the RAM in your computer for faults.
https://www.memtest86.com/
And an open-source memtest86+ (for older PCs, such as mine happens to be):
o Memtest86+ is released under the terms of the Gnu Public License
http://www.memtest.org/

Then, I bought extra RAM and filled all slots. I had to
drop the clock down to DDR3-1866 before it stopped
throwing errors.

As you noted about RAM speed, the article also discussed that:
o How to Enable Intel XMP to Make Your RAM Run at Its Advertised Speeds

How to check your PC's full specifications on Windows 10
https://www.windowscentral.com/how-check-your-computer-full-specifications-windows-10

Since this is an AMD CPU, this applies:
"If you have an AMD CPU instead, you may be able to enable AMP,
AMD Memory Profiles. This is AMD¡¦s version of Intel's XMP."

That reference says to use CPU-Z to check the current memory timing:
o CPU-Z, System information software
https://www.cpuid.com/softwares/cpu-z.html

The motherboard manual doesn't always
label these well.

I haven't played with memory in decades so I don't remember, offhand, if I
can leave just one DIMM card in a slot, or if I need them in adjacent
pairs, or, if they have to be staggered - but I'll get to that soon.

(This was sent earlier in the day many hours ago but failed due to
VPN & Usenet script setup issues on the new machine being immense but
unrelated to this hardware problem.)
