Low IOPS with Samsung 950 Pro 256GB on AMD system.

[hurricane28]

Regarding the high wattage being used when shut down, i don't know if it makes any difference but i am on an very very power hungry AMD system

It does not matter how power hungry the CPU is, when the computer is shut down, the CPU should be drawing nothing. Even in standby, the CPU is doing nothing.

I called Cooler Master and they said it must be the PSU so i decided to do an RMA service from them.

This is happening now? Or did you already get this replacement and have the same problem?

i RMA my ram and go from there..

While Memtest is not conclusive, you did get no errors. Did you try running with 1/2 your RAM at a time?

If this were years ago, I would also suggest you inspect your motherboard for leaky or bulging electrolytic capacitors. Most motherboards now use solid caps. But you still might inspect your board to make sure all look good.

Ah of course, thnx for pointing that out.

Yes this is happening now, i called them and they said that it must be the PSU since there is no other hardware issue in my system and i know this because i ran every stability/stress test program i know without any problem for extended period of time.

I can assure you there is nothing wrong with the ram, i tested the ram with memtest the first day i got my ram and let it run over night and it was stable as a rock and no errors to be found. if there was anything wrong with the ram memtest would find it. To be sure i also did run the Windows memory tool and yet again no errors. The only thing i can think of is the CPU and the PSU but since i stressed the CPU to its limits without breaking a sweat for an extended period of time, i am almost sure it the PSU because i had this same exact error before and it was solved by a new PSU. The only question is why is this the second PSU that went wrong on me. I asked Cooler Master it they would be so kind to test the PSU since they have an proper PSU tester in their lab, to give me some advice or maybe can determain what the cause is.

I checked the board and i couldn't see any leaking/bulging capacitors but i will inspect the board again just to be sure.
I don't know why the system is still drawing 65 watts when idling, the whole system is not shut down but only a part is still running like the Motherboard is still running, the Corsair h100i GTX, my 3 harddrives, all of my fans and my fan controller, so i guess that is enough to pull 65 watts for some reason, i don't know.

Hi guys,

I did an RMA request to Cooler Master and they approved, Monday i will get my new PSU so i can test further from there. I also noticed that my wall socket is not grounded which can cause all kinds of issues.. SO i am going to replace that and try to ground it, if there is a problem you always have to go back to the basic and the basic is wall socket first than look further. If that doesn't help i don't know anymore.. I also want to check for malware or any other crappy software just to make sure my Installation is working as it should because my PC is behaving a little weird, one day its fine and the other day its laggy and just weird, don't know how to explain it. Also when i remove the side panel i hear static noise over the speakers which can be an indication that the wall socket is not properly grounded or something so its a logical way to start. I will try on a different grounded socket and see what happens.

An ungrounded wall outlet is more a safety problem than anything - if that is all that is wrong. But an ungrounded outlet can also result in interference issues too. In any case, when you have multiple devices connected to the same outlet (computer, monitor, speakers, printer, network gear, etc.) it is best they all be properly grounded together (creating a "common ground"), and to Earth ground. I recommend all home owners and computer users have access to a AC Outlet Tester to ensure your outlet is properly wired and grounded. I recommend one with a GFCI (ground fault circuit interrupt) indicator as it can be used to test bathroom and kitchen outlets (those near water) too. These testers can be found for your type and voltage outlet, foreign or domestic, at most home improvement stores, or even the electrical department at Walmart. And if a fault is shown, have it fixed by a qualified electrician.

Yes indeed. An ungrounded wall outlet can cause all kinds of interference and it can even reduce live span of electronic equipment. Can i test this with an multimeter as well instead of an AC outlet tester? I already emailed the company i rent my apartment from so i hope they will fix it soon. I also read that my insurance doesn't cover fire or any other damage which is caused by an ungrounded wall outlet.. so for safety reasons alone i should fix this ASAP.

Ummm, no it won't, not if a missing ground in the wall outlet is the only problem. As I noted before, it is really just a safety issue. And to that, it really is only a problem if the device connected to the wall outlet is faulty or damaged. In any case, a missing Earth ground alone does not affect component aging.

Remember, there are several types of grounds - including "floating" grounds. Automotive electronics are not grounded to "Earth" ground. Neither are avionics (aircraft electronics). Double insulated devices use two-connector plugs - they don't use the 3rd wire. They depend on isolation/insulation and the polarity of the outlet being correct - this is why one slot (in US outlets) is longer than the other - so the plug can only be inserted into the outlet one way, thus ensuring proper polarity (assuming the outlet is properly wired).

Yes you can check with a multimeter but I must caution, ANY THING that plugs into the wall can KILL!!!! This includes meter probes if mishandled or you slip. This is why those testers are so nice and safe. The tester's connectors are molded into the tester's housing and cannot slip. And the tester can only go in one way. And finally, it interprets the readings for you. No need for you to worry about which is "hot" and which is "neutral".

I was going to post a link to a guide for testing with a multimeter, but I don't know where you live so I don't know what type outlets you have, or the voltages used. Since we are talking about a potentially deadly procedure, I will not assume you meant Holland as I don't know if "The Neterlands" shown as your location in your user profile is an acceptable alternative spelling for "The Netherlands", or if "The Neterlands" is some fictional place.

Okay, well as i told you before i am not an electrician so i don't know but a fried of mine is and he told me that ungrounded wall sockets can cause interference and can shorten life span Pc parts.
There is little more to it but my english is not that great to explain but i hope you will understand what i mean.

Yes playing with electricity is very dangerous indeed, that's why i ask before i do anything myself.
I do live in the Netherlands an no its not an fictive place its only misinterpreted as "Holland" which IS an fictive place, this will explain why: Holland vs the Netherlands - YouTube

BTW, i did received my new PSU today and i already built it in my system and it feels that my system is more responsive than with the other PSU but i am not sure yet. Three is no way to test this so lets hope for the best. The only way is to let an electrician come over and he has to redo all the wiring which the company i rent my apartment from will never approve for, so in my case there is little to nothing i can do to be certain what is going on. The only thing i can do is ask the company i rent my apartment from is to ground my wall sockets.

I am not an "electrician" either, but you can follow the link in my sig and see that I am an "electronics technician" and do have a pretty good understanding of how power affects electronics. Basically, electricians deliver power to buildings and wire the buildings to get power to the electronics. Electronics technicians troubleshoot, maintain and repair electronic devices like computers, TVs, control consoles, communications equipment, etc.

Your friend is absolutely right that interference issues may result from poor or missing grounds. But not about shortening life spans. A missing ground to Earth alone will not affect the expected life of any component. There would have to be other factors involved to shorten lifespans - like excessive heat, or excessive voltages or current (which cause excessive heat).

I know that Holland is the same (more or less) as the Netherlands. I've been to Amsterdam a couple times and also Rotterdam and The Hague. I just note that you have "The Neterlands" (with no "h") under your name in your profile so I could not be sure if that was an accepted alternative spelling for the Netherlands, a misspelling, or a fictional place.

and it feels that my system is more responsive than with the other PSU but i am not sure yet.

Responsiveness is not really a function of the PSU. If the PSU works, the computer runs. If the PSU does not work, the computer does not run. If the PSU is not stable, the computer reboots or shuts down. It does not "respond" faster or slower, depending on the PSU. So your "feeling" that it more responsive is the placebo affect.

Three is no way to test this so lets hope for the best. The only way is to let an electrician come over and he has to redo all the wiring which the company i rent my apartment from will never approve for, so in my case there is little to nothing i can do to be certain what is going on.

Not sure what you mean here. There are outlet testers for your type wall outlets. Or an electrician can test them. As far as repairs, yes, that would be up to the apartment owners. But if a certified electrician finds the outlet's wiring is unsafe and/or not up to code, I am sure there are laws and regulations in the Netherlands that require landlords fix them - and quickly too.

The only problem there that I see is your landlord getting mad at you and raising your rent or kicking you out. If your electrician friend is "certified/bonded" and will test your outlets for free, then great. Otherwise, I would get a tester (I recommend everyone have access to a tester anyway) and if it shows the outlets (check all in your apartment - especially those in the bathroom/WC and kitchen areas) are bad, then "nicely" inform the landlord. He certainly does not want all the bad attention a little kid getting electrocuted would bring down upon him!

If he does not correct them in a reasonable amount of time (you would have to decide what is reasonable), then he should be reported to your city's public safety/code enforcement people. And if the tester does show you have bad outlets, I recommend you let your neighbors borrow your tester and have them check their outlets too. There's power in numbers.
