hi, I purchased a Inspiron laptop which has 8 gigs of RAM and Intel Core i5 8th generation processor. I purchased another 8gigs of Crucial Ram. after installing the ram the laptop was pretty fast for a couple of hours. The next morning the laptop went back to it original speed. I run Lightroom photo software, which is about 2 GB. Suspecting something is not right with the Rams I downloaded a memory test. After running the memory test I found out that laptop recognizes all 8 processors but it only keeps four of them active. Please see the attached picture from mem86 test. I just don't know why the laptop is not operating at full capacity. Thank you in advance. Any help is greatly appreciated

Are you saying it recognizes only 4 processors or 8 gigs of ram ? "After running the memory test I found out that laptop recognizes all 8 processors but it only keeps four of them active"

It could just be memtest that does not use the max number of cpus.
The test itself was supposed to figure out what's causing the slowdown. I'd highly doubt that it would use less CPUs than available.. having said that I still have no clue why system would be slow

I may be way off here. But I've read that certain UEFI firmwares have issues when using multiple CPU's and thus, I believe, multiple cores. THat's why you can specify, via a cfg file, to disable multi cpu mode.
Whether that is the issue here? I have no idea. But as for a test of the RAM I'd think the number of CPU's should be irrelevant.

Click HERE to see a page that tells you how to edit the cfg file specific to their RAM tester.
