Windows 7: BSOD again

Okay, BSOD again.

This time I was doing a search through a PDF file and I got BSOD.
Here is the dmp file and perfmon report.

The latest dmp file is dated 12 oct.

Well, I memtest while sleeping and came up with 6 errors.

I'll try replacing the ram later and run tests using the new ram chip.

1 error was in the 47mb area, the other 5 were in the 4000 mb area, same spot.

You might want to test each RAM stick separately, one at a time to isolate the bad one. YOU should also test each RAM slot with a known good stick.

I'm actually thinking of changing it to a 2x2gb config from a 4x1gb that I am currently using now though.

I'll try and check the individual slots/chips to see which is the one giving me errors.

Okay, I did extensive testing today.
Running 4 chips, I get tons of errors.

But running 1 chip at a time, I get 0 errors even with different slots.

What now? How am I going to diagnose this problem?

Sounds like I was right.

Same thing on my system with 4x2GB (two different kits of 2x2GB, each of which is fine on its own in either pair of coloured slots)

I haven't yet tried getting my system stable with 4 sticks, but what I'd try is the higher NB voltage with the 'stock' CL5 timings and default RAM voltage. (My logic says the looser timings should be easier on the NB)

Hi Pirl,

Thanks for staying with me on this issue. And with the others as well.

I did try higher NB voltage -> it was @ 1.4v when the thing just died on me and memtest gave me tons of errors.
But after that, I was on looser CL5 timing, the stock is CL4, but I left the NB @ 1.4.

Then I did further tests using CL5 , nb @ 1.4v and did the single chip/single slot , double chip + double slot test. And went through them fine.

5-5-5-16, does this sound about right?
I had the DRAM volts at 2.2, which is what the ram is made for, should I decrease/increase this?
Now it's set to AUTO in bios.

I reverted all voltages back to AUTO and i managed to boot up into windows with 4 chips.

5-5-5-18 1.8v is what mine is currently running at (set to auto with a kit rated at 4-4-4-12 2.1v)
However, I've only got two sticks at the moment (I need the stability for now, will tinker with four sticks in a couple of weeks - what I'm saying now is what I plan to try myself when I can)

Set the RAM to auto and bump the NB voltage +1.0, +1.5, +2.0 volts (as long as that's still under 1.6v)
If it's still crashing, 1.9v at CL5 with +1.0 NB, +1.5, +2.0.
If still then, do a bit more research.

I was able to boot and run windows for between 10 minutes and almost two days before it'd blue screen, so it's unfortunately not always quick to see if the changes make any real difference.

You mean +0.1v NB right?
Because auto = 1.1v , if I add in +1 then it's above 1.6.

I'll try the suggestion out Pril, but for now I need to get some work done. :s

I am not a RAM expert by any means. The good news is, you have found your problem. It looks like your RAM slots are OK. Now to solve it. For that, I am going to call in the RAM experts. Be patient and you will get some really good help with this.
