Hello,

I`m hoping that I`m asking in the right place. This site helped me a lot in the past via google results however on my current problem I can`t find any solution.

A few years ago I bought myself a new pc including the components:
MSI B75A-G43
Intel i7 3770K
8GB DDR3 1600Mhz GSKILL
Sapphire HD7970

Until the point that my HD7970 broke down about a year and a half ago I never had problems with the system. The card just stopped giving any output so I ordered a Sapphire r9 390 nitro. After installing the new card I started to have problems with crashes to desktop when playing games. I figured it was due to not reinstalling windows and figured it would come later. The crashes were not to often. After a while I upgraded to windows10 but the crashes kept happening.

I send the card to the supplyer who tested it and found nothing wrong with it. During that time I used an old Sapphire Toxic HD5850 without problems. It managed to run games like Overwatch or Totalwar Warhammer at lowest settings and never crashed.

In the following months it seemed like the crashes came around a lot more often. Nearly every game that I frequent started to crash. Totalwar Warhammer(within 15minutes), Planet Coaster(within 15minutes), Overwatch (30minutish), Xcom2(30minutish). Once I started playing PUBG crashes became more frequent including memory error(read write).

So, figuring that was due to my GFX card since it started when upgrading I bought a new MSI 1060gtx 6GB. It started promising however crashes just took longer to popup.

By now I`m lost. I`ve tested a lot:
Virus scanner(AVG)
Several reinstalls of W10
Different powersupply
Windows tests of memory
Windows tests of harddiscs
Switched RAM from slot 0+1 to 0+2 to enable dual channel what din`t give any crashes for 2 days until it started crashing several times an hour.
Bios upgrade
Tons of bios changes
Trying different GFX drivers
Trying different chipset drivers(haven`t installed any before started trouble shooting a few weeks ago)

Only thing I haven`t done yet is resetting my BIOS.

It also does not matter if I run a game on lowest or highest details, windowed or fullscreen.

Games always crash to desktop, on rare crashes also windows goes bluescreen but most of the time shows desktop very short.

I do not crash in Windows. Not even when watching multimedia like Netflix.

Only thing I can think of now is: either my memory is bad or 8GB isn`t enough. Especially a game like PUBG is memory hungry. however I usually run nothing but the game during play and the memory seems to cap at 80%. I don`t want to start buying DDR3 memory if I`m not sure since the memory is useless in new systems. I don`t feel the need to upgrade my CPU which should be fine enough. One other thing could be a faulty mainboard. This brings the problem of the complete lack of 1155 socket mainboards out there by now.

I also never did any OC.

Anyone has any idea on what I could test more? Any pointers on how to proceed. I think I spend a LOT of time changing and testing(40-50 hours?). I don`t feel like upgrading since the system should still perform just fine.

Looking forward to any useful advice and I thank in advance!

David

EDIT: when changing so the sapphire r9 390 I also got a new case and powersupply since the supply at the time only had 1x 8pin. The new supply was a Corsair RM70x. At this moment the old supply(620watt) is in the machine to test

You get a lot more with both in, shame you cannot run 1 stick in a different slot to see if stick 1 gave stacks of errors in slot 4, for instance. I assume PC tells you to have 1 stick in slot 1 and 2 in 2 & 4?

Stick 2 does look bad, without two sticks that actually work you cannot tell if its just the stick causing the discrepancy in errors in the tests you ran with 8gb
It could be that test 2 of the 8gb test had bad stick in slot 2 - and it didn't mess up - and other two tests have it in slot 4, where it does play up or is discovered more easily.

I would get 16gb of ram and run memtest on the new ones. Sticks should be fine but it will tell you if slot 4 is okay as well. If you can borrow the ram, even better as its a cheaper test...

MERGED QUESTION
Question from Shomey : "memtest64 with 757errors in 40minuts"



there are various versions of memtest out there but I believe they all share 1 thing. the perfect score for errors is 0, any errors show you the stick needs to be replaced

Did you run it 1 stick at a time, so that you know which one is faulty?

If I know for sure that either one of the sticks is bad I`ll just buy atleast 16gigs of new memory and throw these out. I`m guessing it`s fair to assume that my system errors come from bad memory then. Just weird that with older gfx cards I din`t have the issue`s. Maybe due to less memory use in general and maybe the memory got worse over time.

I would test ram and if its only 1 stick that reports errors, use the other one and test the ram slots. No point buying new ram to find it is a slot causing the errors, it might save you some cash. Can use memtest for the testing the slots.

bad ram will corrupt data and cause all sorts of strange errors

Are you on win 7 or 10? 10 uses ram in different ways to 7, it uses it a lot more as well, as its possible if you had 7 before, the system just wasn't using all the ram all the time, and the area of ram reporting errors never got used in the past.

1. In win 7, when you closed a program or game, windows would dump it all back onto hdd so you got your ram back again.
In win 10, when you close a program or game, win 10 will compress the data into ram so that if you reopen it, its a lot faster to load compared to if it is on hdd. If you then run a program that needs the ram, windows will then copy it onto hdd. This means that Ram gets more use in win 10

2. Another thing is due to way win 10 shutdown normally, your PC will use ram more. win 10 uses hybred hibernate meaning when you turn PC off, its not really off. Its asleep, half the open info is saved into ram and other half onto the page file. This means startup is much faster as there is less to load.

Both these 2 things combine to meaning Win 10 tests ram a lot more than previous versions did. They are both good things though, they make PC much more responsive.

Okey that is very good to know. I guess I`m kinda pushing it with 8gb ram by now. Concidering my GFX got upgraded 2 times and I demand much more from my system,

I ran the same test a second time. After 1hour and 45minutes no memory errors. I`m at a loss right now :(

did you use all the slots?

your manual isn't very helpful, I can tell dimm 1 & 3 is one channel and Dimm 2 & 4 is another.

Not sure how Memtest can report 757 errors 1 test and none the next? seems more testing is required, I would let them run longer and check 1 more time as current test results are even... and mysterious.

I tested again with the same setup:
167errors in 1:20hours, with a restart before

Then tested with one 4gb in slot1
0errors in 1:21hours, with a restart
0errors in 0:50, with restart and system cooldown time

I`m now gaming a little with that setting.

Going to test more and then report back

Thanks for the help so far! I`m finially having some progress in finding the issue it seems.

same setup? whats in the 1st setup? was it 2 sticks in slots 1 & 3?

stick in slot1 seems okay, what is difference between it and 1st setup? Did you test other stick in slot1?

Are sticks from the same set or did you buy separately? Why weren't you running dual channel originally?

What I did with Memtest:
I have 2x 4GB GSKILL riptide 1600Mhz

8GB test in slot 2 and 4, 757 errors in 0:45 minutes
8GB test in slot 2 and 4, 0 errors in 1:40 hours
8GB test in slot 2 and 4 167 errors in 1:20 hours
4GB test with stick 1 in slot 1, 0 errors in 1:21 hours
4GB test with stick 1 in slot 1, 0 errors in 0:50 minutes
4GB test with stick 1 in slot 1, 0 errors in 1:20 hours
4GB test with stick 2 in slot 1, 1 errors in test stopped somehow, ran atleast 1 hour
4GB test with stick 2 in slot 1, 1 errors in 0:53 minutes

So my second memory stick gives errors. First one din`t. With the both of them at the same time I get more errors.

Is there use testing more or different motherboard slots or is it safe to assume that one memory stick is broken?
