BSOD after building in new Ram

[AgeT]

Hello there
I buuilt in new Ram a week ago , and hadnt had problems so far. Today
my pc randomly starts crashing, and bluescreen gives me a memory_managemnt error , so i guessed on the new Ram
Here are my specs
CPU : Intel Core 2 Extreme QX9650
Mainboard : EVGA nForce 780i SLI
Memory: 8GB DDR2 - 4 times 2 GB OCZP10662G
Graphics : 2 times Nvidia GForce 8800 GTX with SlI
OS : Windows 7 64 Bit

I dont know what causes the error and i dont know how to fix it... tried to set the timings to 6-6-6-18 but didnt help , i didnt touch the voltage tough , its set at 1.85 at bios

here is my crashdump

Try using only 2 modules of ram and see what happens.

Also, what power supply you have?

 

[AgeT]

ok ill do that later, but why does this occur now ? from one day to the other ?
uhh , dont know , where do i find that ?

 

[trancedellic]

Depending on the case the power supply is in the back, at the top/bottom of the case.

Judging by your sli video cards you should have something above 450-500 W.

You can try to test your memory with memtest86 too.

 

[AgeT]

ok wait i check , btw , what should be the right volatge for the ram ? i read somewhere that it should be 2.1 but on other places tey say 1.8 etc...

 

[AgeT]

thats mine here

 

[trancedellic]

It's ok. Pretty good power supply.

You tried to OC the memory? Can you post a screen for the memory in cpu-z? At 800 Mhz they should run ok but at 1066 sometimes they have problems.

 

[AgeT]

no , i run it at 800 MHz , its just the voltage that i am not sure about which to take , in Cpu-z , what does the case in the bottomr ight corner mean ? wait ill highlight it

 

[AgeT]

p.s. have you taken a look at the minidump ? what confuses me are those 3 passages :

and

DEFAULT_BUCKET_ID: WIN7_DRIVER_FAULT

and this one

IMAGE_NAME: ntkrnlmp.exe

i cant find a realation bewteen them

 

[trancedellic]

Well, if you only changed your ram and you have problems then you should test them.

Run Memtest86+ for at least 8-10 passes. It may take up to 20 passes to find problems. Make sure to run it once after the system has been on for a few hours and is warm, and then also run it again when the system has been off for a few hours and is cold. How to Test and Diagnose RAM Issues with Memtest86+

I had few years ago 2 modules of faulty ram and I had errors and bsods out of nowhere. Tested them with memtest and red sectors everywhere

 

[AgeT]

heres my cpuz

what bothers me are the 3 rows that are orange
what does the first mean ?
Why do the others differ ?

 

[AgeT]

i cant run the system for hours, it just crashes after 20 mins or so , randomly , no idea why

 

[trancedellic]

It's voltage and timings for every frequency.

They run now at 400 mhz ( x 2 ) as you said.

You should be ok testing the ram because you need to do it from a bootable device( cd/usb stick).

 

[AgeT]

ok so at 400 Mhz , 1.85 shopuld be fine ?
ill run that memtest then i guess, how long does that take ?

 

[trancedellic]

It's best you leave it for at least 7 passes but if the ram is faulty you should see results fasts. I saw my errors after like 30 mins. I had 2 gb Kingston DDR2 running at 667 Mhz.

 

[AgeT]

have a look at this , in bios it says im running at 1.85 V , but when i run hardware monitoring software , it says the ram only urns at 1.6 , whats wrong ?

 

[trancedellic]

Voltages are different for almost every ram and motherboard. It depends on the quality too. High quality ram doesn't need that much voltage at 1066 Mhz ( 2.1 V) for example.

Test the ram and post the results.

 

[AgeT]

the test is currenttly running but , shall i raise voltage , in case there are no errors?

 

[trancedellic]

No need for now. The voltage is good if it's stable for you.

Last time I checked my voltage was ~1.5 V. And I have 8 gb ddr 3 at 1333 Mhz ( Corsair).

I checked now and I see your MB supports max 8 gb ram ddr2. You should try to remove two modules of ram to see if the problem persists.

 

[AgeT]

yes my mb supports max 8gigs thats why i bought 8 gigs also , many many users of the same MB recommand the ram i use , so it should be compatible.
after 2 and a half runs, i found 1 red sector ( twice ) , uhm i dont know what it tells me , what info you need from the memtest ?
