memtest86 or memtest86+?

[mrbios]

Which one is the best option for testing?

I'm using memtest86+ at the moment but i don't know whether to trust it....I tested some ram the other day and all came out ok (2 hour run time each time) then i ran it again today as i couldn't remember which sticks i'd tested and within the first few seconds i got 1 solitary error which was apparently on test #4, but if i try and run test 4 on its own it just starts running test 3 o_O test 4 doesn't seem to exist!

After getting that solitary error i thought, i don't believe you, and restarted it. Now it's been running for 20 minutes with zero errors again. WTF?

I've got loads of ram to sell on the MM soon so i need to be certain that it's all 100% good.

Think I was just using the regular memtest, had a similar thing testing a couple of sticks the other week, 1 hour run and no errors, restarted pc and gave another 1 hour run to get 30 odd errors, then again and got 300+.

Been running for 3 hours and 12 minutes now. Still no errors even though it flashed up one error prior to the restart. Confused....

I've got 7 sets of corsair ram here, and i thought i'd have to RMA two, but now I'm not sure...i know one is definitely faulty, but the other one flagged up a single error just like the ones I'm testing now. Maybe that one isn't faulty at all and it's just some memtest bug.
