Memtest86+ result question

[mangaforall]

Hi All,

i'm trying to figure why i'm having ramdom BSOD with different messages every time and while testing my RAM with memtest86+ individually for each module, 2 modules out of 4 came up with the below errors:

Failing addresses are different but rest of columns are similar. Any one got an explaination ? That looks weird to me and i start to not believe anymore the result of that program.
I used different software to test other part of the hardware such as furmark, prime95 etc. and so far i'm thinking there is no hardware issue because i still get BSOD while i took out those 2 memory modules that show up with errors (it is most likely a driver that corrupt the memory).

Of course i could be very unlucky and have driver issue + bad memory.

TO narrow down those BSOD i need to understand the memtest result.

thank you !
Lu

Also remember to check if the memory is compatible with your motherboard! Sometimes some modules are either faulty or don't operate with some motherboards.
As for the results, hopefully someone with some experience in memtest86 can assist you!

thanks for the hint, i use Corsair Vengeance with a BIOSTAR Z87X-3D and it should be fine.

Dear many times associate BSOD with RAM. Well, that's true but some times it is actually the PSU. In case it can't provide enough voltage to the system, you may get BSOD and system gets rebooted. Pl check your PSU. RAMs are compatible with the mobo. Though you better update your mobo BIOS and after doing that clear CMOS.

How would you check if the PSU is not OK ? I took care of buying a good enough one (Corsair CX600M) while my rig is not overclocked. On the paper there shouldn't be issue.

Also indeed there was an BIOS update provided 3 weeks ago for this mobo but i didn't try to update yet.

CX series PSU does not have high quality capacitors. This series is an average series. Anyhow you may update the BIOS and see if it works

Will try BIOS update after checking couple others things first.

Also still looking for someone to help analyzing the memtest result from my first post !

What is the actual model # of the DRAM? Looks to be 1600/10 sticks

 

[mangaforall]

it is corsair vengeance 8Go DDR3 1600 (CMZ8GX3M1A1600C10)

 

[Tradesman1]

If failing individually, looks to be bad sticks. Timings and all appear to be fine, might be RMA time 🙁

 

[mangaforall]

but why columns display same information with 2 different modules ? (except failing address).
This is brand new RAM by the way

 

[Tradesman1]

I would try DRAM first, next would be to check mobo and CPU, for many that's harder to check

I took away already those 2 memory modules (using the 2 others that passed successfully the test). Still having BSOD. That's why i want to understand the memtest result.

Sorry for late reply. Test no 7 i.e Block move has failed for your DRAMs in its second pass (4mb blocks of memory are moved around using the movsl instruction). Good and bad shows what data was copied/written and what was retrieved. Any difference in these two (In your case there are differences unfortunately) will reflect the error and err-Bits are showing the exact bits which are failing.

Above description is bit tech. I would recommend you to use only one module at a time and run memtest86 on it. Then run the test on second module. This is the sort of accurate way to test and identify the RAM module which is faulty.

If modules came ok after tests, then check your mobo and CPU and don't forget check your PSU as well.

1- I tested individually each memory module i have as mentioned previously
2-Isn't it surprising to see that with 2 different memory modules, i see the same good/bad values ? what are the odds to be the same ? ==> that's the main reason for my post
3- I'd like to test the PSU, any suggestion ? I read 600W should be enough for my config but PSU issue could explain why the BSOD are always differents
