Windows 7: BSOD'S after installing RAM

BSOD'S after installing RAM

Today i have installed 4 gb more ram on my machine. Difference is just the speed, rest is the same, so i doubt it can cause the problem. After couple hours I've got first bsod, after relaunching windows there was an error "The ofcommon.dll is missing" and after couple more minutes it crashed again. Now running for 30 minutes, no problems so far.
Any help will be appriciated.

30min after, crashed again.

That should be enough difference.

If you want to enhance memory, get one that is essentially identical with the existing one.

Hi, thank you for your answer.
As far as i know my motherboard Asus p5q se runs at maximum 800hz. My old Corsair 2x2gb ram was 1033 CL7 if im right, that never made any problems. What i bought is the same corsair 2x2gb just 800hz CL5. Seller said it will make no difference and everything should work perfectly. Would be amazing to get some info what dmp file says.

Will try that software from a tip when come back home.

The different memory modules probably will "work" but all installed memory will run at the lowest compatible speed of the slowest module. The key word here is compatible speed. If the BIOS can't negotiate a compatible speed, you'll get errors. The dump says you're getting Memory Management Errors or more specifically, memory corruption. Hmmmmmm Wonder why.

You could try running Memtest86.
