Windows 7: RAM bsod on the first bsod, bccode 1a

RAM bsod on the first boot, bccode 1a

Hello,i've recently purchased 3 memory sticks of the same brand and model (it wasnt a kit though) and that is when i started getting bsod on the first boot after around 5-10 min of running the os,the weird thing is that i dont get another bsod if i have already had one.Im not sure if the memory is defective as i've done 8 hours of testing with memtest86 and it was just fine (i ran all 3 sticks together,might wanna do it 1 by 1).I tried using default bios setting and optimized defaults but to no avail.If i throw my previous ram back in (wich is a kit of 3x2gb) i dont get any bsods or whatsoever.I've attached recent dump files extracted via sf diagnostic tool and filled in my pc info in the according profile section.
Any help is appreciated,thanks

Hello DanielKuzmin.

Your crash dumps are not showing any finite probable cause. In such a situation, it is better to enable Driver Verifier to monitor the drivers.
Driver Verifier - Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

information   Information
Why Driver Verifier:
It puts a stress on the drivers, ans so it makes the unstable drivers crash. Hopefully the driver that crashes is recorded in the memory dump.

How Can we know that DV is enabled:
It will make the system bit of slow, laggy.

warning   Warning
Before enabling DV, make it sure that you have earlier System restore points made in your computer. You can check it easily by using CCleaner looking at Tools > System Restore.

If there is no points, make a System Restore Point manually before enabling DV.

Tip   Tip

Test your RAM modules for possible errors.
How to Test and Diagnose RAM Issues with Memtest86+
Run memtest for at least 8 passes, preferably overnight.

Let us know the results, with the subsequent crash dumps, if any.
