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

I am now on a combination of slots 2 and 4.. I'm getting second thoughts about whether i am not able to put all 4 sticks in and let it work..
anyway, as you said i am now in dual channel mode..
but uhhm.. I have left a blue and a green RAM card..
I opened my little brother's PC (holy shit have never seen so much dust before, LAYERS i tell you.) anyway, as he was whining about minecraft being slow (which isnt so demanding so thats why i thought it was odd), i also checked his ram, he appears to have 2x1GB ram, and a 2GB green ram card, which might be identical to the one laying here..
so 2x apacher and 2x hyundai might be an option, so the colors are identical and so are the cards?

I am now still on slots 2 and 4, i tried putting ram sticks in slots 1 or 3(+ 2 and 4) but that resulted in restarting of my computer..
so i tried to put them all inside.. the hyundai cards on slot 1(white),2,3(white) and the apacher one on slot 4(black)
I was cheered up because it went past the windows is loading thing.. but after it finished 'welcome' it gave me a BSOD saying: Reference by pointer

Here the dmp file, hopefully you are able to indicate what's wrong.

Code:

REFERENCE_BY_POINTER (18)

BugCheck 18, {0, fffffa800c5e5970, 2, fffff8a002f5413f}

Probably caused by : ntkrnlmp.exe ( nt! ?? ::FNODOBFM::`string'+53feb )

STOP 0x00000018: REFERENCE_BY_POINTER

One of the usual causes is hardware.

:/ so I'm not sure whats broken..
all ram cards work, a black slot MUST be filled in order to let the PC boot.. but if black and white are used in a combination, its a disaster..

It might have been lost in my verbiage.

You have the wrong memory for your machine.

See if the store/website will replace the memory with correct sticks

Crucial Scan your system to view your specific system configuration.

And here's what Crucial says for a Acer Aspire M7811 Desktop/PC.

Memory Type: DDR3 PC3-8500, DDR3 PC3-12800, DDR3 PC3-10600, DDR3 (non-ECC)
Maximum Memory: 8GB
Slots: 4
Each memory slot can hold DDR3 PC3-8500, DDR3 PC3-12800, DDR3 PC3-10600 with a maximum of 2GB per slot.

There is no reference to PC3-10700 (667 MHz)

I also noticed on my own machine that Speccy apperantly has a bug when reporting memory. I have two slots - it reports 1. The actual memory reported is correct.

I'm beginning to distrust Speccy reports on your machine. Post #35 - says you have 3 Hyundai sticks. This might not be the fault of Speccy, but a manifestation of the issue on your machine.

Could you post a msinfo32 for me? You'll have to compressed in a zip folder to attach it on a post - thanks.

As far as your memory working before, possible, but you are getting BSODs.

Get the correct memory, put it in the same colored slots - one pair at a time to test. Make sure they are firmly placed in the slot.

Unitl the memory is of the correct type, there's not a whole that van be done.

Run with just the single PC3-8500F (533 MHz) - Apacer until you pair that one or buy a set of four matched sticks.

I wasn't exactly clear when I psoted before, although I did say that the memory was mismatched and of the wrong type. Sorry it took me a while to clear that up.

Replace the Hyundai memory with mobo matched type
run with only mobo matched Apacer until correctly paired
How you want to pair them is up to you
a) 1 additional Apacer
b) 3 additional Apacer
c) 4 new faster sticks

edit: You are powering down, disconnecting the power cord, and dissipating any static eletricity before chaning hardware - right?

PhonicStudios · 13 Nov 2012

oh sh!t... I usually do not plug out the power cord... i did once but today i forgot about it..
and uhhm, I doubt a store/website will replace my used, not bought at their store ram cards without charging >.>

I am currently running with the PC-3 10700 and the PC3-8500F, 4 gigabyte.. dual channel and my computer is working fine.. more laggy than before, running BF3 with 85% usage of my memory, okay its unfortunate but working... for now..
so you are suggesting me to buy new PC-3 8500 Apacer ram cards? If so, I'll have them (if fortunate) by christmas..

oh and I attached the ms32info to the post.

Thanks for helping, more suggestions are always appreciated.

Slartybart · 13 Nov 2012

I only use the Crucial site as a reference - you can purchase memory from any manufacturer/vendor as long as they are correct for your machine.

Since you got this machine second hand, you might consider a clean install once you straighten out the memry issue.

PhonicStudios · 13 Nov 2012

I've already reformatted the drives and reinstalled windows 7 when I got this computer, mainly due another problem which was posted on a dutch help forums..
but i'll surely clean my computer out

Slartybart · 13 Nov 2012

Here's what I suggested:
Remove the 10700 sticks
run with the one PC3-8500 stick until you can buy matched pairs that are compatible with your machine

Use Cruical as a guide (they have help on installing too). You can sort the reference page by price - go high to low so you see the 2GB x 2 pairs first. I don't think you're interested in 1GB x 2 (they show up first if sorted by price low to high)

Buy the fastest memory that is compatible with your machine and fits your budget. That's about it.

You might ask the store where you originally purchased the 10700 about their return policy - who knows, it might save you some money.

re: Power -Always disconect all power and discharge any remaining charge BEFORE working on hardware.

Power down, pull the power cord and hold the power button down for at least 30 seconds.
Touch a metal part of the chasis to discharge any static on your body every time you remove or install a component. Technicians use a strap clipped to the chasis to free their hands.

Thanks for the msinfo - I'll take a look

Could you attach the raw .nfo file from msinfo (just save, not save as) - I don't read Dutch.

When you say - clean up your PC, what exactly are you going to clean? There's a lot on there - games, tools (suspect some might cause your machine problems.

I'll tell you what, fix the memory issue first and then figure out what to do next. We're not getting anywhere this way. The Optimize Windows tutorial might help "cleaning up".

I'm out of other suggestions until you fix the memory issue.
