I blew up a CPU while benchmarking... FAIL

2017-01-15
okay this one was raw and and we're talking like Chatsworth raw if you know what I'm saying I just tweeted out that I blew up a processor and we're going to talk about that two things happened here but it was kind of like I was in the middle of doing a different video and now I'm making this video obviously as you guys wanted me to do this video about how it blew up maybe you guys can learn something and yeah we're doing this this is this has to be done I air all my mistakes this as you might recognize is the budget gaming system I built out of my own money to kind of do a series here where I upgraded over time and see what kind of decisions I make when I'm putting my own money on the line it was some pretty interesting choices here and it ended up in a form not final form it's still not in final form but within 8320 from AMD and and GA 990 fxaa ud3 motherboard allowing for overclocking and such ever since I did the KB like shoot out video a few days back I could not stop this nagging feeling that there was better gaming performance to be had even from like five-year-old processor technology here almost six years old at this point when the 8300 series launched then there was on any hyper-threading case queue overclocking i3 available on the market today I thought you know what this needs to be done I need to test this I took the SSD and the 1080 out of the KB leg rig behind me there and I put them in this rig here and decided to put it through the exact same tested it with the i3 i5 and i7 to see how it really compared and guess what we were seeing some pretty damn impressive numbers from the 8320 overclock to 4.4 gigahertz compared to the i3 at 4.7 it was beating it and Cinebench it was beating it in time spy and I get to do the rest of my tests and we're going to talk about why so I started getting greedy and I went you know what I bet this CPU has at least four point six and even if I could get four point seven out of it that'd be awesome because then we have another direct four point seven gigahertz comparison yes I know the architectures are different yes I know AMD and Intel direct frequency speed is not comparable across platforms I know that it just would have been neat being like hey all of these were at four point seven kudos well the ud3 was being kind of weird where even though I was telling it to do one point four five volts which is very safe even with a cooler like this one here which is this isn't a hyper 212 a Cambridge one it is it's a step below the 212 a sub plenty of cooling effect we were only seeing 60 C on the package at the one point four or five volts at four point four so I was happy with that I figured we got more room than that so I put in 1.5 volts and that's safe I believe in is still safe for AMD it sits on the edge of air cooling you know you really got to keep an eye on things I noticed that when I was doing Cinebench that the voltage was dropping down to one point three one to five ish like one point three one to five one point three three between there and then the cores were slowing down to four point three even though I had them set to four point six so that donned on me oh yeah I didn't change the line load calibration settings in the motherboard see what happens when you put these CPUs graphics cards are the same as well about to explain here when you put them under load there becomes a bit of a voltage drop across the board where even though you're telling you its end at one point four it might only get one point three or whatever because as the CPU is fluctuating and doing its different tasks it starts to pull voltage you get what's called a V group and where the voltage won't be steady across the board so what you have to do is go into overclocking settings and most good motherboards are designed for overclocking here and have good line load calibration settings in there where you can basically tell it to take whatever the baseline is and add a percentage of voltage to it so that you can say okay you want to account for the drop so under load or line load calibration let's go ahead and go to either normal or extreme profiles as different settings on there basically like I said the percentage increase of voltage across the board to allow for that droop so I put the multiplier to a 4.6 gigahertz setting went into Windows no problems whatsoever went in two times by beat the i3 no problems whatsoever b2 CPU score beat it on GPU score and it beat it just on combine everything with this like I think this is awesome I'm going to be able to show people there's no point in buying the 70 350 K so then I went it to Cinebench and I had hardware monitor going so I could keep track of things like the voltages to temperatures all of that stuff I'm monitoring everything and I'd noticed something interesting that it's going 1.5 1.5 v 1.59 1 point 6 volts on air I'm going wow that's interesting it's it's going up quite a bit on voltage but it passed the test and I saw that max temperatures were only sitting at about 67 C on the package and I thought well it's actually not that bad but you know what that's not safe that's not safe at all so I should probably shut down the system go back into BIOS and then see you know pull the voltage back down a little bit to account for the line load calibrations can add a little bit more so I tell the system to restart and this motherboard has something interesting in it where when you tell us to restart it will power down completely and then turn back on whereas a lot of motherboards will stay powered on as a the constant voltage supply and then just restart itself well this one because like I said it turns off when I hit restart the system turned off and then it powers back on and immediately powers right back off and doesn't come back and I'm seeing the telltale sign here of uh-oh because every time I push power I would get just an immediate flick of power the fans would all kind of fudge for a second and then stop that's usually a sign of something is wrong with CPU power delivery yeah I was like oh that's not good so I cleared CMOS no it no repair whatsoever took out the graphics card took out the memory took out everything except for the CPU on there same result unplug the power delivery to the CPU the eight pin EPS power the system turns on now it's very it's very unlikely that the motherboard is bad on this I have a fact I have another CPU that I'll find some time later to drop in here so I can old 6300 drop it in here if it powers on I know the motherboard is good I'll buy a new CPU we'll be back up and running and then that series can continue but I want to explain why this happened and what I should have done differently so the first understand why the CPU died you have to understand how motherboards work and how they turn on now certain parts of your motherboard are always under constant power and twelve volt supply if that wasn't the case and when you push power nothing would happen right because that's plugged into your motherboard so there's always parts of your motherboard that are powered on waiting for a momentary switch like your power button to tell it to turn on well the way it turns on is it basically slaps your system across the face with voltage and says hey turn on when you do that usually those voltages when they first turn on are spikes there's they're much higher than the initial voltages are going to run out so it's kind of like a quick peak of power high voltage and then it comes down really fast to say hey you know this is what we're supposed to run at because as it does its post and it starts loading up the BIOS that's when it goes here's what the voltage is need to be it looks an awful lot like because the voltages were set so high and with line load calibration and because it basically took a base of 1.5 and then slapped it with voltage who knows what it hit it with but the moment it tried to turn it on and it slaps it across his face like Ronda Rousey's recent fight it died that's when it died here's what I should have done differently when I realized the voltages were so high especially after I already knew that this freakin motherboard turns itself off to restart I should have just powered it down cleared the CMOS and then I wouldn't have had this issue had I done that the system would be alive today I'd be able to do all the benchmarks and show you guys more definitive proof that it is absolutely unnecessary to buy the 73 50k yes I know a m3 has no upgrade path yes I know blah blah blah blah blah insert all day and be hate here but it still was beating the i3 73 50k hands-down and it's a hell of a lot cheaper to be able to achieve that because with the 73 50k you have to buy an expensive z2 70 board to be able to take advantage of all those overclocking features so when you put those two together you spending at least $300 upwards of 350 400 depending on what you want and yes there is no pre pads you can upgrade the CPU later but there's no point in spending one hundred and eighty-nine dollars on a CPU just upgrade it later just save more up front and buy a better CPU to start 73 50k shouldn't exist as far as I'm concerned at the price that it does so there's my opinion on that but anyway that's just that's it I wanted to kind of tell you guys that hey we were beating it we were beating the 73 50k what's the 8320 I was proud of that and this is one of them highly unedited videos but that's okay because allow me to share this with you guys so if you think your voltages might be too high or you think if something is wrong dear self a favor clear your CMOS before restarting your system especially if the voltages are really high like mine was I'm an idiot I was impatient I wanted to get the video done and guess what now I don't get to do the video at all and I've got spend more money out of my pocket to get another AMD processor because of the fact that I blew it up and no I'm not going to allow someone to send me one and I'm not going to ask for one for sponsorship because the whole point of this build was be out-of-pocket what I just experienced was a mistake of mine does cost me money out-of-pocket so the best I can do is at least feel the pain of spending another 150 dollars on an 83 20 E and get it up and running from there or just decide what I'm going to upgrade it to in the future there you go guys a first processor I've killed in over to over Kenya it's probably more like 15 years at this point maybe even more the last processor I've I killed was a pentium d so you do the math I killed a pentium d alright guys time to go I'm depressed I don't like killing hardware I don't care if it's expensive hardware and I don't care if it's cheap hardware I don't like killing hardware and this is this is up there with me on how I felt after drilling holes in the motherboard
