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 tempted and I didn't 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 triple-channel just want to clarify this some one looks a little bit confused about 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 a single channel and any quad channel motherboard is capable of running single dual or triple or quad so the way that you do that is you populate the DIMM slots in the correct order so here you can see we've got a 1 and B 1 right there so if you wanted to run into a channel you'd go a 1 B 1 then if you wanted to run in triple channel you'd populate C 1 and if you wanted to turn in quad channel you'd populate D 1 so there you go that's how you do it right now it's running in quad channel because I do have 4 memory sticks in here I also had a lot of people commenting on the fact that I wasn't using them test 86 mem test 86 is awesome great memory diagnostic utility it runs before the operating system which is really really good at tests all of the memory and it throws a big read errors if it detects anything the problem is that the issue I was having was not being detected by mem test 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 Linux are Linpack or any of the other sort of Intel burn test 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 prime95 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 mem test 86 wasn't working for me is what prompted me to use prime95 if meant works to detect the error that you're getting then that's great however there are even times prime95 detects nothing mem test 86 comes up with errors in like five 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 men test 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 because I'm lazy or they actually have a 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 right what other people ask that was really really really good yes this is a really good one so people a lot of people asked how did you rule out the motherboard the CPU the power supply all that stuff so this is a very important part of any sort of troubleshooting scenarios you got to make sure am I actually isolating the right components oh I knew it was the Wrentham because I'd had this motherboard with this CPU with this power supply running with this Kingston HyperX memory at these speeds so 1600 c920 command rate all of that good stuff so that's how I rolled up the motherboard that's how I've ruled out the CPU and power supply you got a 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 ever let 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 ones this one errors in prime95 this one errors in a multi-channel configuration eventually haha that's another one it had a lot of people commenting - 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 configure 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 coast or it 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 Claire clears up some of the questions you guys had don't forget to subscribe Cline is tech tip from unboxings reviews and other computer videos I love this camera using the fs700 today I was using the XA 10 last time the Mike'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 wrong Mike I'm sorry one more thing in spite of my warnings to the contrary I did have a couple people saying oh my room is stable enough it works in games and just cuz it fails in prime95 after an hour doesn't mean it's not so yes it does it means it's not stable it isn't stable it's not good enough 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 last thing is it has to be stable in every in every stress test it has to be stable and prime stable and mem test stable and Linux a stable system is stable and doesn't make mistakes when I'm done this prime95 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 gonna run the whole thing through mem test 86 again once I'm done here in order to reassure myself that all of this is working completely a hundred percent before I redeploy it in a system and another thing I forgot it had a lot of people saying - you have so much memory why don't you just throw it away and buy a new memory memory so cheap what are you crazy throw away Hardware cheese way to be moneybags 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 and you throw it away
