BSOD - IRQL not less or equal, Page fault, Memory Management, etc.

It is 6 GB in both CPUz and Speccy but 4 GD in system information.

Re-seat the modules? It may bring it back to normal.

You're allowed to facepalm, go ahead.
But uhhm, what do you mean with re-seat? just put them in different slots?

Arc · 12 Nov 2012

Try in different available slots, not a bad idea at all.

The sticks are mismatched and Speccy reports 2 used - 2 free,
but then describes 3 slots filled

So you advise me to buy more RAM?
anyway, I have figured out something, every time i put a ram stick in the last port so:

| | | | <<< that one, i get a BSOD, or it reboots when starting..

Also, I tried many different ways of putting htem in, but I just CANT get to 6GB RAM... theres 3x2GB sticks in there, as 1 slot is damaged in a way I can't use it.. whatever I do windows keeps recognizing it as 4GB ram..

oh and heres the dmpfile for the BSOD.
so anyone any idea? also this:

when using just two ram sticks, so 2x2, and i use it like this:
| X | X , X is empty slot, anyway my computer starts making a constant beep...
when using this:
| | X X it just shows 2GB RAM..

doing it this way:
| | | X like I have it right now, it shows 4GB ram..

Confusing isn't it?

Sounds like a bad motherboard slot if it's only one port you are getting the BSOD in.

Code:

MEMORY_MANAGEMENT (1a)

BugCheck 1A, {403, fffff6800001ace8, 974000006ae0b867, fffff680000170e8}

Probably caused by : ntkrnlmp.exe ( nt! ?? ::FNODOBFM::`string'+320ec )

STOP 0x0000001A: MEMORY_MANAGEMENT

One of the usual causes for this BSOD is related to memory.

A few things I have noticed. You haven't stated what ram you use. Your motherboard supports DDR-3 1066/1333. I'm unable to find a motherboard manual. I hope you have one so you can make sure the ram is installed in the proper position. You have a dual channel system as far as I can tell. That tells me you either install 2 sticks of ram or 4 sticks of ram but I'm unable to tell you when using 2 stick which slots to use without the motherboard manual. Your CPU supports dual channel the same ram as your motherboard up to 8 gigs.
Do you have a motherboard manual?
What ram are you using? It's not in your specs.
If it was my computer I would test the ram two sticks at a time installed as per the motherboard manual location. The ram must be matched and bios set to default.
If the test on the ram passes I would replace the two stick with the other two sticks. If they pass I would install 4 matched sticks of ram. If it doesn't pass I would think its a motherboard.
No over clocking until this problem is fixed. Also keep everything unplugged for the computer until it is fixed. Examples: printer, usb drives, card readers, head phones ect.

I linked to the crucial site so you could compare what they recommend for your machine against what you have in your machine.

You have two different types of memory, the one matching pair and one origianal stick.
slot-1 new
slot2-old
slot3-new
slot4-empty

Depaneding on your mother board
1 & 3 could be paired (in that case your memory was install the correct way) or they could be paired
1 & 2 (in that case your memory was installed the wrong way)

Some mobos are particular about an odd number of sticks, and the order of installation (slower 1st or slower last) I think as a rule of thumb - faster and paired go first.

I have not benn able to find info on your machine or board that would help.

Do you have a link in your favorites? Most Mfrs stick the model reference page in htere so users can use it when needed..... it's needed.

Please post it if you still have the PC model reference in your favorites - probably in Acer.

Thanks,

Bill

Layback: Ram inforamtion is in the Speccy report - I aslo check Crucial a few posts after
