Problem with the mother board or the power supply

[Zrnkichi]

I made a new sistem with a M5A99FX pro 2 from asus with a fx 8350 stock cooler, a gtx 970 amp extreme form zotac (the frist one the one with leds and dual conectios to the power supply of 8) 8gb ram gskill 4x2 (it was from my old sistem) and a power supply OCZ Fatal1ty 750 w (also from my old system). Then i bougth 16gb ram 4x4 kingston hyper x fury and the problem started. frist i thougt memorys was broken, so i did memtest 1 by 1 and all give me btw 50 and 56 errores in test 2, 3 and 4, and if i test all together the made an orgy of errors until it restarted. Well i change memory in the store, and when install all again and make the memtest it get the same amount of error.

At that pint i thougth it was the mobo that was broken. Since i went to a frind house with the same mobo and the memorys didnt made a single error.

At last before i call asus i made new test but this time i change the gpu for a hd6950 and disconected both hd wd black 7200 and de dvd rw. This time the test was succesfull 0 errors. I change the gpu again for the GTX 970 (this version have an oc chip that you ahve to conect to a usb port from the mother to work) with th oc uncconected and again a succesfull memtes. I pluged the OC chip and, again a succesfull test. Last time i pluged both hd and the dvd rw and the memtest made an error fest.


So i cant managed to get a power supply to probe it, so i have that both "thories" that is the power supply or is the mobo. I cant prove the Power supply since i dont know how to do it properly.

So what is the chance that the mobo dont work properly? Or is the power supply that for some reazon isnt working properly?


Thz in advance

Its most probably your PSU. Try to borrow one from a friend or a neighbor and test again. See if it helps !!

WEll i tried with a PSU from a friend that bougth it yesterday, and there where no errors en memtest. Then I checked again with my psu, no erros also. Now im kinda lost.

Then your motherboard is at fault. Replacing it is best option for you now.

Well now after using the pc for a time i made a memtest again and the errors are back. Dunno if it is the Mobo after all, or is the PSU.

How old is this PC? Is it a OEM prebuilt or did you make it yourself?? Can you give me a detailed parts list of your PC?? You obviously have some problem somewhere in your pc otherwise you would not be getting these errors.

Edit: Give me a parts list like this example using pcpartpicker.com

This is my gaming computer configuration.

WEll sorry for the time, i send the motherboard to the rma and they checked it and they couldnt replicate the error... so they give it back, i mounted it again http://pcpartpicker.com/p/MphwXL this is basically what i have. Still the ram do errors.... i prove it in other systems and it worked well....I dont know what it could be...

A little Update. When i perform a memtest Sometimes, specially if i reboot PC and perform a memtest it make errors, a lot of em. But if i go to configuration of memtest nad change the number of pass to 1 instead of 4 it dont make errors, then i mkae it 4, it do not make errors again. I dont know if is a memtest bug, or is other thing in the configurations. I updated the bios i setted memory with the DOCP. Im really lsot here, i proved all things i know about it. Btw the ppl of the RMA say that they have no problems, i dont know if it can be some sort of uncampatibility btw memorys, micro and mobo.

Frankly I too was very stumped then I saw your system configuration. The ram sticks are from 2 different stock and the cpu is overclocked right. Did you update your BIOS to the latest version?? If not, try that and see what happens. If the problem is still not resolved you might have to increase dram voltage and cpu/nb voltage manually in the BIOS. The two threads linked below discuss similar problems and solution. Read through them and try their advice to fix your system.
