Hello all,
This is my first post here and I was wondering if you could help me out.
I´ve just bought a Yoga 7i laptop from Lenovo and I´ve decided to run memtest86 to check the memory because it´s soldered to the motherboard.
I´ve ran a 10-pass test and it passed without any issues, but I had to get a replacement due screen issues.
The replacement arrived an I´ve noticed that sometimes things were taking more time than usual to open and Lenovo app froze for a couple seconds when I was trying to adjust it.
I thought it was odd and decided to run memtest86 again and sure enough an error showed up. Actually two errors on "Test 7 - Moving Inversions".
So, I´ve stopeed the test and restarted all over again running the exact same 10-pass test and this time no errors were found.
Which test should I believe?
Is there any aditional testing I can run to make sure my system is good?
Should I update the Bios or something?
I´m still in the return window and I don´t want to get a third replacement unless I have to but at the same time I don´t want a defect ram soldered to the motherboard.
I´ve attached both reports to this post.
Any advice is greatly appreciated.
Do I have a defect ram or not? What would you do if you were me?
