mobo - asus z87-pro (v-edition)
cpu - intel core i7 4770k (haswell)
memory - corsair vengeance 16gb (2x8), DDR3, 1600Mhz
(more specs will be added if needed)

I want to know about versions because in screenshots i see alot of people use version 4.20.

i wanted to test my memory, but i dont know which version of memtest86+ to use. i was checking the websites download versions and there is 4.20 and 5.01. I don't know which one i should use for my system. plus i read that version 5.01 has some bugs with freezing.

i noticed in the changelog that version 5.01 has preliminary support for haswell, what does this mean for me? does version 4.20 not support my cpu or will it be good to use?

Also i noticed there is an ISO format which i know you have to burn to CD and boot from the cd, and there is a usb installer version, which allows me to boot from a usb drive.

Are they both the same thing? is the ISO format more reliable than the USB format or is it the same?

will i get the same results using iso format as i would using the usb format? can using the usb format cause errors that the iso format would not?

Also should i keep the monitor on the entire time of running the test or can i turn it off? will turning the monitor on and off during the test cause any errors (im asking because i use my TV for my monitor and dont want any burn-ins of the testing to appear on my screen, i also have a backup monitor i dont mind leaving on)

also i have noticed SMT and SMP modes or something like that, what mode should i use? or whats the difference testing with or without these modes enabled?

Any input would be much appreciated.

Just get the USB version from their website:
http://www.memtest.org/#downiso

If it freezes, it freezes. It's not a big issues. It's such a minimal interface, I wouldn't worry about it. It's pretty straight forward and stable in any version.

Ignore everything else, you are making it over complicated.

If you have any RAM errors, it will start generating errors pretty quickly. You can leave it alone for as long as you want, as long as your system is well cooled. It's just a basic Linux kernel.

what if the errors dont show quickly, what if i get 1 error after 5 passes? which recently happened while i was testing and i had monitor on and off a lot and using the usb version.

1 error means there's an error. Test each RAM stick individually. The tests will be shorter that way.

That's fine, just leave it running for a bit. In theory, it should run 100% successful for all time, if your system is stable.
