Hi all, I've been having some weird issues that I can't be sure are memory related. It's lengthy but I'm trying to explain what all I did and why it's so confusing.
Last December I bought an 8GB memory set for my HP dv7t Quad (Core i7 720QM) laptop, the memory model is F3-10666CL9D-8GBSQ. Shortly after installing them I started to get a random BSOD for MEMORY_MANAGEMENT, but it is so rare and usually happens when I am away from the computer. The past month or so I have also been having my web browser random close quite often, sometimes 5 times in an hour (I use Palemoon/Firefox and it is constantly using over 500MB).
This week was dedicated to memory tests, I ran memtest86+ almost every evening in various configurations. I started with how it had been set up for months and I managed to get some errors in test 5 that were around 2000MB and 3000MB. The next step was to run each stick individually... no errors after 10 hours on each stick. I then put them both back in and ran the test again, no errors again. I then switched the sticks around and ran again, got errors in the same spots. I also tried using the standard memtest86 and the Windows Memory Diagnostic available on the Ultimate Boot CD, neither of which showed any errors at all with both sticks in. I also found MemTest 4.0 from HCI Designs that runs within windows, and it found an error in one of the 3 sessions but did not say where it was.
I have since put my original sticks into the laptop which were 1 2GB and 1 1GB stick from Samsung. Thus far (less than 12 hours) I have not had a single random browser close and no BSOD. I am wondering if the problem is the sticks themselves or dual channel being used(I assume dual channel only works if both sticks are the same size). I looked in the BIOS and can't find a way to disable dual channel, or any advanced BIOS options at all, and I do have the most recent BIOS from HP.
Does anyone have any opinions as to what I can try before trying a new set of memory? If it is related to the dual channel I'll just live with it and get mismatched sticks, not going to send it in under warranty for something easily by-passable.
