Windows 7: Memtest results - How to interpret

Memtest results - How to interpret

I just built a new machine and it looks working fine but a memtest(Memtest86 v.4.20) returned errors whose screen shot is as follows.
What exactly does this mean beyond that the errors were detected?
1. Is the Test #7 being done when this shot was taken?
2. The error happened while the test #6 was running?
3. The error happened for bits pattern of b4ffl1ff?
4. Are all bit patterns tried for each test of #0, #1, #2, , , ?
5. What does the "Bits in Error" mean?
6. What do "Pass 37%" and "Test 72%" mean?

Hiyya churin mate I know this will sound rather tedious but personally I would run memtest with each stick in separately as it could be just one of the sticks that is bad.
That is stick 1 in slot 1 and then 2 then stick 2 the same config.
If that doesn't come up with anything it could be a slot.

That readout I have not seen it show like that before as usually the errors are shown as red bars that go across the width of the screen like in the pic.

Sorry mate should have asked what memtest did you download as there are two that look similar
this one Memtest86+ - Advanced Memory Diagnostic Tool or
PassMark MemTest86 - Memory Diagnostic Tool

I downloaded both of them and found both are named the same or Memtest86 v.4.20. Anyway I am trying one of them and the screen display is different from that as posted in my previous post. It is over 3 hours now since but no error is shown yet. I wonder how long it should be run.

At least 8 passes churin if possible overnight it does take whle to do. Of course if you get errors up staight away you don't need to go for a long time.

Now the difference between those memtest is the readouts plus the download links for them list one as memtest 86 and the other memtest 86+ I think I always use the top ref when I Google for it though once I got the disk made I just keep it tucked away for future use.

Memtest 86 and Memtest86+ and different programs.
We stopped using Memtest86 years ago because the developer was not updating it to work with newer RAM regularly. I only use Memtest86+ from Memtest.org now.

I understand that Passmark software purchased Memtest86 from the original developer and is reissuing it. I don't know if it has been updated to work with the newest RAM.

But for best results in getting feedback in this forum I would stick to Memtest86+ - since that's what most folks are familiar with.

Thanks TV I had an idea that there was something about the Passmark one I've only ever used the one that you have used too and I think churin was using that Passmark because of what that original readout looked like and why I posted the pic to show him what it should look like

One of the two utilities ICit2lol posted looked just like the screen shot I previously posted. Since it looked the same I immediateley quit running it. I ran other one for 8 hours whose screen snap is attached as follows. The settings as shown are all wrong. They should be 800MHz, DDR3-1600 and 9-9-9-24.

Are you sure you have the right memtest as in this one Memtest86+ - Advanced Memory Diagnostic Tool it has to be the 86+ one as TVeblen said the Passmark one is out.

The screen shot looks the same in the last one you sent why is should be showing the RAM like that when it clearly is not the RAM you have has got me beat.

I know it is tedious churin but make another bootable disk and run again. The link is above and just check in the BIOS to see what the RAM is listed as. Speccy will do that as well and if the two match then there s something wrong with the memtest download. Just follow the tutorial link I sent before as well.

Yep. The program in the above screenshot is the Passmark one. Get rid of it.
You must see that + sign in the title name to be the correct Memtest86+ .

That program is confused. It thinks it is still 1998 and can't understand how a RAM stick can be larger than 512MB!
