after I got so many great messages on YouTube about the RAM testing video I
uploaded yesterday see I've got four sticks going here
now I thought I'd do an update video just to address a lot of the questions
and concerns and comments that you guys had so as you can see I did finish my
24-hour test with the three modules I had before which were running in trip
Channel just want to clarify this someone was a little bit confused about
uh how you can run triple channel in a quad Channel motherboard so to clarify
guys any dual Channel motherboard is capable of running single Channel any
triple Channel motherboard is capable of running dual Channel or single Channel
and any quad Channel motherboard is capable of running single dual or triple
or quad channel so the way that you do that is you populate the dim slots in
the correct order so here you can see we've got
A1 and B1 right there so if you wanted to run a
dual Channel you'd go A1 B1 then if you
wanted to run in triple Channel you'd populate C1 and if you wanted to run in
Quad Channel you'd populate D1 so there you go that's how you do it right now
it's running in Quad Channel because I do have four memory sticks in here I
also had a lot of people commenting on the fact that I wasn't using m test 86
mest 86 is awesome great memory diagnostic utility it runs before the
operating system which is really really good it tests all of the memory and it throws up big red errors if it detects
anything the problem is that the issue I was having was not being detected by
mest 86 so the reason I was stubbornly using prime 95 is because I don't I'm a
little bit old school and I'm not using uh Linc s linac or any of the other sort
of Intel burn chest these are all tools that I haven't really used that much
plus I knew that I could consistently reproduce the errors on these sticks
with a prime 95 test after a certain amount of time this is just a test bench
this is not my main machine so I'm not that concerned with it not being running
at any given moment so the fact that
mest 86 wasn't working for me is what prompted me to use prime 95 if mem test
Works to detect the error that you're getting then that's great however there
are even times Prime 95 detects nothing m test 86 comes up with errors in like 5
seconds so you can never really predict which tool is going to be the one that
is going to find the problem with what you're doing although people in the
comments are right generally speaking mest 86 is the first one to go for they
have all kinds of awesome ways to run it so you can just burn the iso to a CD
which is what I usually do just cuz I'm lazy um or they actually have see I just
didn't want to empty a USB drive they have a USB drive Creator so you just
throw a blank USB drive in and it will go ahead and fix all that up for you so
uh right what other people asked that was really really really good yes this
is a really good one so people a lot of people asked how did you ru rule out the
motherboard the CPU the power supply all
that stuff so this is a very important part of any sort of troubleshooting
scenario is you got to make sure am I actually isolating the right component
so I knew it was the RAM because I'd had this motherboard with this CPU with this
power supply running with this Kingston
hyperx memory at these speeds
so600 uh C9 ont command rate all of that
good stuff so that's how I ruled out the motherboard that's how I ruled out the
CPU and the power supply you got to rule out things like heat I'm running on an
open test platform with air flow directly over the fan or the RAM itself
so we can pretty much rule out heat how do you rule out your RAM settings well
because this memory was running at these settings in the past so that's how I
know that it should be fine assuming nothing's gone wrong with it in the
meantime so these are my two dead this one errors in Prime 95 this one
errors in a multi- channel configuration
eventually aha that's another one I had a lot of people commenting lonus you
idiot why didn't you just run one stick at a time guys if you'd watch the video
you'd know I had already run all of the sticks individually this stick the one
right there on the left passes on its own but as soon as you put it in a
multi- channel configuration it the entire thing fails whereas all of these
sticks all together in a multi Channel config are not failing so that's how I
know that this guy right here with the duct tape is dead that one on the left
is borderline which is not good enough it's for all intents and purposes dead
but it's much harder to catch compared to one that's just outright dead doesn't
post or causes blue screens right away so I think that pretty much covers
it thank you for checking out this sort of updated video on diagnosing memory I
hope this clar clears up some of the questions you guys had don't forget to
subscribe to lineus Tech tips for unboxings reviews and other computer
videos I love this camera using the fs700 today I was using the XA 10 last
time the mic's terrible though I don't have my lapel mic I'm using the shotgun
mic that's on the top so before you complain about the audio just I know
it's the wrong mic it's bad oh well
you'll get over
it I'm sorry one more thing in spite of my warnings to the contrary I did have a
couple people saying oh my R is stable enough it worked in games and just cuz
it fails in Prime 95 after an hour doesn't mean it's not yes it does it
means it's not stable it isn't stable it's not good enough uh if it ever
crashes when your computer's doing something critical it can completely corrupt your entire OS and make it non-
bootable the odds of that happening I don't know you roll that die uh last
thing is it has to be stable in every in
every stress test it has to be stable in Prime stable in m test stable in Linux a
stable system is stable and doesn't make mistakes when I'm done this Prime 95
test just for good measure because remember that fourth stick has been in
my wife's machine so I for all I know it's dead too so I'm going to run the
whole thing through m test 86 again once I'm done here in order to reassure
myself that all of this is working completely 100% before I redeploy it in
a system and another thing I forgot I had
a lot of people saying lius you have so much memory why don't you just throw it
away and buy new memory memory is so cheap what are you crazy throw away
Hardware jeez way to be money bags no you don't
throw away Hardware you test it you see if it works
if it works you keep it if it doesn't
work then you throw it away
