memtest86+ showing different speeds for memory slots

XMP is an Intel setting. I've never seen that on an AMD board. You can pretty much do the same thing, but you have to do it by hand. But, it being an older AMD board and an HP machine, I doubt you have any options to change anything.

That's right, I think AMD calls it AMP on their boards.

CMOS reset. BIOS settings to default.
Same readings from memtest, CPU-Z, and Speccy.

I think it's pretty clearly a motherboard issue. If I get more BSODs, I'll pull that one stick of RAM...I'll still have 12 GB, so it's not like it's going to make the system unusable.

Thanks for the tips. May not have a solution (well, other than buying a new computer which would probably be about the same money as replacing the MB)...but at least it seems you've helped me definitively identify the problem.

Running 3 sticks in a dual channel system may knock all the RAM down to single channel mode. (Check your motherboard manual)
You may not notice any performance difference in single channel mode either. Depends on what you are doing. Video editing, you'll notice.

CPU-Z showed it still running in Dual when there were three sticks installed.
No BSOD lately (and yes, I'm sure I just jinxed myself), so I'm going to mark this thread as solved and thank you all for your help.
