Always the same value of difference

[pavel_v]

Hello,
I'm having some troubles with my PC recently, so I ran memtest86 7.1 from USB. It found quite a lot of errors. Now I'm not sure how to interpret it. Does it means something, that the difference between good and bad value is always 1000? (for example: Expected: FFFFFFFF, Actual: FFFFEFFF). This rule applies for all found errors.

This is amount of errors:

Test	Errors
0	0
1	0
2	0
3	1
4	891
5	6995
6	4680
7	3758
8	2163
9	339
10	0
13	344

I'm not sure how to interpret it

Getting 10,000+ RAM errors is not a good thing.

RAM is likely bad.

that the difference between good and bad value is always 1000

It means it is a single bit error, which is the most common RAM error.
