Hi,
short version:
Im looking for an alternative to prime and everest to test the stability of my overclocked system, since strangely, those apps are stable while some games are no longer when overclocked.
Full story:
I have an old 65nm C2D E6400 that I decided to try and overclock and it does admirably, from 2.13 GHz to 3.3+ prime and everest stable at pretty much stock voltage.
Some games however, do crash at these speeds (seems stable up to ~3.2) and Im at a loss why.. well, aside from the obvious.
The obvious cause is the CPU, but like I said, I can run prime (64bit, 2 threads, maximum heat) for several hours, no problems. Same with Everest.
- I doubt its the RAM as memtest86 passes with no issues (despite having a couple of DDR-667 Dimms in the mix, running @410+ MHz).
- I doubt its the my videocard, since its not overclocked, its cool as a 4870 can be and its stable in furmark.
- I doubt its PSU, as I can run prime and furmark concurrently without issues. Antec 550W also should be enough for this setup.
- Since I can run prime and furmark as long as I want, I think I can exclude 'case' heat as problem as well; I would anyway, since everything is as cool as you can hope for given the specs and overclock; cpu sensor doesnt break 50C package / 65C in core running prime, videocard doesnt break 60C GPU in furmark, although VRMs get hotter than Id like, but no different than at stock cpu speed, and still quite a bit hotter in furmark where its stable as in the games where it crashes.
- I doubt its a PCI bus problem, as I have it locked at 100 Mhz
Dont know what that leaves, other than it being the obvious, ie, the cpu or FSB, perhaps chipset, and apparently something in games is taxing my cpu in a way that prime doesnt, so Im looking for an alternative before start increasing voltages.
In short, I want an app to reliably crash my machine
In case it matters, motherboard is a gigabyte GA-965P-DS4
