Hi Gravarty: Thank you very much for joining the Intel® Processors communities. We are sorry to hear that the PC is not working properly.
In regard to your inquiry, at this point it is hard to tell for sure if the source of problem is the processor, there might be different factors that could be causing this behavior, could be the motherboard, could be video card or even the memory RAM itself.
We can run a test on the processor just to confirm if it shows some errors and if it is working at the correct temperature and specifications:
The RAM seems to be fully compatible with the processor:
Do you have the option to test the PC without the video card?
Even though you just replaced the memory RAM, please test the PC using just one memory stick at the time, just to rule out a possible problem with it or with the memory slots.
The problem could also be related to the application you are using for video rendering, since it might be taken all the resources from the processor and that is why it is reaching 100% of processor usage and crashing.
If the problem persists after that, then the next thing to do, if it is possible, will be to test your processor on a different board or test your board with a different processor.
Any further questions, please let me know.
Yes it's supported: P8Z77-V LX | Motherboards | ASUS USA
I also tried to downgrade the bios because some motherboards tend to crash old cpu's when they include support for newer processors and it actually helped a bit, it took some more seconds until it BSOD again.
Memtest86+ also didn't show any errors, all RAM sticks are fine too. Intel-Processor-Diagnostic-Tool passed everything just fine.
Before i had the i7 2600, i was using the i5 3450 which didn't had any of these problems. I know that the i7 2600 is kind of a "semi downgrade" since it only supports 1333 MHz RAM & PICe 2 but i wanted Hyper-Threading, so..
EDIT: Okay, that's strange, why do all other cpu intensive programs completely crash the computer on any OS but the CPU-Z stress test runs just fine?
EDIT 2: HeavyLoad also works just fine
So it's safe to assume that the CPU is fine? I mean it would be horrible if i actually bought a broken CPU, there's no way i could return that now
