I've been having a lot of trouble with freezing and bsods with my computer lately, so I took the chance to do a full upgrade.
My new system only shares the VGA with the old one, nothing more. Current specs are:
- MOBO Gigabyte 970a-d3 AM3+
- 2x4GB Patriot PSD34G160081
- NVidia geforce 560 TI
- ADATA SSD 256GB
- 2 old HDDs for data storage
- Windows 8 x64
In my bad luck, even with my new system I kept having freezing and bsods. I started running some tests. First thing was memtest, which was keeping failing on test #5 on every single ram module, on different slots.
I had both the ram replaced with other two of the same model, only to have memtest fail again in the exact same way.
I started fiddling a bit with DRAM voltage (not much, just upping by 0.05 at a time a couple of times) and lowering the frequency from 1600 to 1333 with no results.
Also, Prime95 fails on all tests (small FFT, large FFT, blend), with blend almost always ending in a bsod with CLOCK_WATCHDOG_TIMEOUT error. The errors reported in Prime95 before it BSODs are rounding errors and sum errors, in all tests.
I then tried the old ram from the old computer. 4x2GB, cannot remember the manufacturer but I'm pretty sure they were Corsair. 0 errors on memtest after 14 hours, but Prime95 fails in the exact same way.
Apart from the tests, the system is unstable, freezing and BSODing randomly, sometimes after a couple of minutes of uptime, sometimes after even one day or more. I got many different BSODs errors, I can get the list and update the post if the could help with the analysis, but the only consistent one is the CLOCK_WATCHDOG_TIMEOUT.
I also tried to rule out the VGA on both the old system and the new system by switching it with another one (an old ATI I had) and I kept having crashes on both systems.
I usually have no problems troubleshooting my hardware but this time I think it's beyond my skills.
Any help will be immensely appreciated.
EDIT
There's no overcloking, no custom bios settings apart for my slight fiddling with DRAM voltage.
EDIT 2
I updated my MOBO bios. As of now, small fft always passes, while large fft and blend fail almost instantly. I haven't had any BSOD since the bios update, but I'm having freezes. Memtest still shows error in test #5.
Still confused. Mobo maybe? Or cpu?
