Hi, i have some troubles after installing additional memory and new OS.
To be more precise, BSOD. Here is the information.

BEFORE

OS: Windows XP SP3 32 bit
RAM: 2GB [2 ranks, 8 banks]
NVIDIA driver: 270.61
CPU: overclocked to 4004 MGz [BCLK 182*22; voltage 1.25]
BOINC: 6.10.60 and 6.12.26, both 32 bit
BOINC projects: cosmology@home + einstein@home

Working normally.

AFTER

OS: Windows 7 Ultimate SP1 64 bit
RAM: 6GB [(2 ranks, 8 banks) + 2*(1 ranks, 8 banks) in dual channel mode]
NVIDIA driver: 275.33
CPU: overclocked to 4004 MGz [BCLK 182*22; voltage 1.25]
BOINC: 6.12.26, 32 bit & 64 bit (both versions give BSOD)
BOINC projects: cosmology@home + einstein@home

Windows crashes after some time (randomly) of BOINC computations (both projects working at same time) — BSOD [IRQL_NOT_LESS_OR_EQUAL, 0x0000000a].

The system is running without errors if I don't use BOINC.

While I was writing this text, there is another error indicating that the problem is likely in the NVidia driver.
When I chose Snooze GPU, the screen blinked and there was an error.

The attached ZIP file contains:
• cpu-z system report;
• windows minidump folder.

Asus P7H55-V, Intel i3-530 [4004 MHz], Gigabyte GTX 560 1GB [GV-N56GOC-1GI], 8GB Hynix [4*HMT325U6BFR8C-H9], Windows 7 Ultimate SP1 64 bit

The first minidump shows that your CPU crashed.
The other minidumps show memory related errors and 32bit vs 64bit errors.
They happened while Einstein was running, once while it was initiating (crash in csrss.exe)

You may have overclocked the i3 too far. First try to run at normal clock speeds, see if you get crashes still. Einstein's science apps do not like overclocked CPUs.

You may have overclocked the i3 too far

But earlier everything worked fine with the same settings.
Anyway, I will try to run the system without overclocking.

But earlier everything worked fine with the same settings.

And a wholly different OS. Windows XP is not as resource hungry as Windows 7 is. On top of that, you went from a 32bit XP to a 64bit W7. The CPU is used differently by the OS, giving something of an overhead you didn't have before.

If all's OK, the science applications didn't change. Einstein has only got 32bit apps for Windows, same for Cosmo.

Still, it's a test. If you can run without BSODs when clocked at normal speed, it was that overclock. I am not saying you cannot overclock, but you may have to run it in a different style than you were used to before.

I raised the CPU voltage to 1.3 and now everything is working correctly.
No BSOD's.

P.S.: Nothing else changed, still overclocked.
