Hi,

after running memtest all 2 I get the following error:

Bit Flip : testing 168 of 256

FAILURE! Data mismatch at local BUFA address 0×0196713c, BUFB address 0×238fedbc
BUFA Data: 0xffefffff, BUFB Data: 0xffedffff

Everything else passed except that. Do you know what could be causing that?

Thanks for the package. I am running memtest on my mac right now because I think that there might be some faulty hardware, I bought it second hand. I just hope it’s not the graphics card or the logic board! :L

When I look at /usr/bin in Finder, I can see memtest, but when I boot into Single-User mode, most of the files that were in /usr/bin are not visible, including memtest. I tried ls -a, and I still don’t see anything. Why would all these files not be available?

Since I’m a big jerk, I have posted a copy of this GPL software at my web site after I paid for it. Sourceforge would host it for free. Hope it was worth the buck fifty, Scamaroni.

You don’t have to use the Terminal or some other über g33k method to see the contents of /usr/bin or any other folder on your hard drive. Simply, from the Finder:
Go (menu) -> Go to Folder… [alternately, Shift-Command-G]
which brings up a tiny window wherein you can type:
/usr/bin
and receive a Finder window with the directory (“folder”) showing the contents therein.

Is there any guidance for how to interpret the reports on the screen?

I do get errors when running the utility in Single User mode, and it hangs as well, so I suppose both are indications of bad RAM, but I was wondering if there are any messages in particular I should be looking at to interpret what’s wrong?
