i want to diagnose the cause of death of this SSD, a samsumg 840 120GB. I had linux instaled on it, and a small windows readable partition. i used linux most of the time, and one time, when it died, the system froze, i tried rebooting, but i could not get the computer to boot with the drive installed. i unplugged it and booted into windows from another drive, and i connected the 840 (sata hotplug enabled) and windows detected it, but activity was at 100% all the time and i couldn't do much on windows. i unplugged it again. set up a linux live usb. from the live usb i can see the drive, can list the contents of /, but i can't perform any action on the drive. it won't be formatted, and won't be unmounted/deleted/anything. I've never seen an SSD fail like this before. Any idea what may have happened? Thank you! i don't care about recovering data, i just want to understand the mode of failure as i've never seen it before. I've checked the components, capacitors and resistors test ok in circuit, no shorts when not expected, no open when not expected. nothing gets unusually hot, no exploded components. last i checked on hwinfo, the life was at 80% remaining about a month before it died, and it was not subject to heavy use in that month. I want to know if anyone has come across this kind of failure, and what it can be attributed to. I thought electric at first, but that seems very unlikely, both after checks, and seeing as it is recognized by computers(i also tried it on a different computer and it showed the same behaviour) thanks again!

hi, yes, i think this disk was released this year, why would it be discontinued? thank you!

i see, if you were looking for a somewhat fast ssd for about 100 ish dollars, would you consider this one over a samsung sata one? of the 480-512 capacity, of course. thank you!

hi! so, i was looking for an ssd for my pc as my hard drive is dying, and i found this one "Kingston Digital SA1000M8" on amazon for about 122 us dollars. at first i was considering getting the samsung 970 evo, but seeing how this one offers pretty much twice the capacity for about the same price and isn't terribly slower than the 970 evo, i'm thinking about this one instead. the thing is, i'm not sure how reliable kingston ssd are, all i've found are forum posts in other sites from about 3 years ago saying they did something with the controller and made them slow? anyways, i was wondering if anyone has experience with kingston nvme ssds and how reliable they are. thank you!

anybody has another idea? thank you!

hi! thank you, i really don't know, i used to have and HD5670 by sapphire, which was a 65w card i believe? and well, it did manage to achieve the same performance reported by others, not in blender since blender only supports 7xxx cards by amd, but in the few games i played. i play league of legends every now and then, and when i had the 5670 it reached 100~frames/s, medium settings at 900p. with the rx460 it is weird because when the game starts it goes up to 220~ fps then starts to go down slowly to 120~, and the cpu sits at 20~30% usage, and the gpu shows peaks from 20 to 100% that look almost like this |,|,|,|,| on afterburner . might be a bad gpu? that's what i've been thinking lately.

Hi! i honestly don't see how it might be bottlenecking the gpu in a blender workload, ( blender loads the tile data in gpu memory, then gpu processes it) and the gpu core utilisation shows as 100% while cpu utilisation is basically the same as idle unless i start another blender instance and start rendering on cpu parallel to the opencl rendering in the other instance, also, when i do render on both cpu and gpu, the gpu times stay the same, about 10 minutes per frame on my last animation, 10 minutes per frame both when rendering another frame with cpu and when only using gpu to render the animation. i have been updating drivers as they arrive for the past few months hoping one would fix it, but it hasn't happened and i'm not expecting it will. it is not overclocked, 1212 MHz is stock settings on that powercolor card. i only overclock the cpu to 3.7GHz. and well, i'm not sure i got a well binned one since a friend who also has one ( he uses it for gaming) by request rendered the same frame on his and it took it 7 minutes while on mine it took 10min 13 seconds (same settings) , also his card showed a power consumption of 60w. unfortunately he lives too far away for me to take my card to his pc or viceversa. thank you!

Hi! so it's been more than half a year since i got my rx 460 and i've noticed it being quite slower than what it was supposed to be, i started checking everything, and saw it was peaking at 35W of power draw, which was strange since it is rated for 75W. i see it shows the load to be 100% in HWinfo64, and the power sometimes peak to 45W but not for more than a second, even when on full load rendering something in blender. both hwinfo and afterburner show the card consuming the 30~35W max, and i wonder what that might be, i've been looking for months about that and i can find nothing. these are my pc specs if anyone wonders. and my psu is a 500w thermaltake tr2. anyone knows what might be the issue? thank you!

hi, i installed different driver versions and that didn't work, i installed various other gpu rvers and that didn't work either blender without music isn't as fun thank you!

hi, yes, this is the uadio codec ALC 892 and my motherboard is listed in the specs image, it is the m4a88td-v evo/usb3 i'm still not sure it has to do with drivers since everything is up to date and was working fine minutes before the issue started? thank you!

everything is updated

Hi! so i've been working for a few hours in various blender models while listening to music on youtube and wmp, and everything was going well until i had a BSOD telling me the cause was atikmdag.sys and a memory block being invalid, so ok, i restarted my pc, nothing new, i finish the work with the model i was working on before the BSOD just fine, but when i started modelling a new thing, i started noticing a very annoying crackling noise when i moved the model in blender or used a brush on it while also playing music in the background. When there is no music playing, there is no crackling sound, but as soon as i open a youtube video or an mp3 with wmp, the crackling starts again, i recorded like 30 seconds of that, but the crackling is only present near the end of the recording(second 18~), but i heard it while recording, if that makes any sense. these are my specs, and the video: any help is welcome, thank you! 2017.02.18-23.28_01.mp4

hi yes, that disk with a warning is from my even older potato pc, i have backed up the important information from that disk to an external disk, i use it to store non essentials like adobe reader, office, winrar, programs i know if anything happens to that drive i can easily replace, the main one is the 2 tb one and that is working ok, no warnings or errors or bad sectors acording to the smart data. thank you!

ooooh, silly me didn't consider the hdd, tomorrow i'll borrow my sister's ssd and clean instal then try again, if it is still slowing things down in games, the overclock still helped me save a couple of seconds of render time with cpu in blender which s my main use of this old potato thank you! ARikozuM!

hi, don't worry, i apreciate you're trying to help! i have the 8 series chipset driver installed and i went and overclocked the cpu an extra 300 mhz for a core clock of 3.7 ghz, and still getting the same results, seems like i need more threads

hi! yes, i even put in a spare hdd and performed a clean windows install+ drivers + the games to test if it could have been software. also, i do't have an intel chipset, if you see my original post, you'll see my pc specs. thank you!

another odd thing! running league of legends at highest settings, i am getting 150 fps( i was getting the same with my old 5670 at high settings) with 50% cpu use and 35% gpu use! a friend of mine has an i7 920 and a gtx 750ti and his game runs at 250 fps, is my cpu really that bad that it bottlenecks a low end gpu playing a not that demanding game? any input is very much apreciated i might be able to save 40 or 50 usd, sell my pc and get a slightly better one, i used to think my pc was not that bad but now i don't feel the same. thank you

hi! but wouldn't a bottlenecked gpu be capped below 100% usage when running intense graphics workloads? i have seen it reach 100% when using it to render scenes in blender and playing rise of the tomb raider, the cpu sue goes from 80 to 100% when running tomb raider and 100% when rendering in blender (using gpu as compute device) so i know in blender something is definitely capping the gpu, again, i might not completely understand how cpus bottleneck gpus. thank you!

hi! i am using the most recent drivers, and yes, i know, but it was a good harvest! i can't afford to upgrade my cpu right now, i might have gotten a bad chip? probably, the card was on amazon for 80 usd and 20 usd MIR so i ended up paying only 60 usd with free shipping so i guess i can't complain that much anyway, it would have been nice to have it run the same as the reviewers' who knows.

hi! so i recently got an rx 460 to replace a damaged hd 5670, and things seem to be woking ok-ish so far, i have a few issues with my 2 monitors but nothing too annoying to be bothered with, anyway, among the few games i play is rise of the tomb raider, and i see benchmarks showing the game running at very high settings at 49~ fps at 1080p and when running the benchmark, i get way less than that, between 30 and 40 the 7 times i ran the benchmark, to get similar results to the online reslts, i have to set it to medium, which give me 52 fps and well, that's fine, i don't mind that much, but it still bothers me, like what might be going wrong? do you have any ideas? attached system config picture. thank you!

hi, yes, i've looked at some used ones but the price wit shipping was a lot more than the 460 from powercolor, i also had a 7790 in mind since it was 60 usd including shipping, but i think a 460 might be useful for a longer time. thank you!

hi! so i need a new gpu since mine failed, people recomended me to get an rx 460, i found this one https://www.amazon.com/PowerColor-460-AXRX-2GBD5-DH-OC/dp/B01J9FFV14/ref=sr_1_5?s=pc&ie=UTF8&qid=1481578991&sr=1-5&keywords=rx+460 for 80 usd, but i've read reviews that say powercolor is not really that good, and some units are DOA and all that, what would you recomend? my budget is really low right now ( the student's curse) but i need a gpu, what do you say? save another 20 usd ang get one from xfx or sapphire? or would powercolor not be that much of a bad purchase? thank you!

now i see this http://www.newegg.com/Product/Product.aspx?Item=N82E16814131695 and many people mention that i need a PCI-e 3.0 board, but i've also seen people run it on pic-e 2.0 boards. mine is this one, do you think i'll have any issues with the card just because i am plugging it in a pci e 2.0 slot? https://www.asus.com/Motherboards/M4A88TDV_EVOUSB3/specifications/ also, anyone has any experience with rebate cards? because i do not live in the us and honestly it's the first time i see the rebate card thingy, if anyone could explain a bit of that to me, that'd be lovely! with the 69 usd price i could purchase it this week i see you have to print the card and mail it physically so i guess i might not be able to, anyway, thank you!

well, thank you both! i will wait and get the 460, i still have time before the next semester begins

thank you! i will see what other people say but i'll keep that in mind
