AMD FX (Bulldozer) Owners Club! - Page 555

Heat is what is causing the errors when you fail a max load stress test. If you are not operating your CPU at load levels that will create that heat then you will not experience those heat levels and will therefore the errors will not happen.

I understand what a CPU "should" be able to do. Especially to be "certified" or such to enter an E-peen club or something of that nature.

If you can game all day every day and not have any issues, does it really matter if when you put an insane load on your rig that it will not perform correctly?

If a car can travel 75 mph and run perfect and never have any issues day in and day out- forever, does it matter (or is it a surprise?) that if you were to pull a ten-ton trailer up a mountain and put a brick on the accelerator you are going to have some engine "errors"?

Not always. And the problems caused by "Heat" in an engine are not the same as those caused by "Heat" in a CPU.

Analogies are by definition not perfect. They are useful to convey general ideas however. If you want to spend your time nit-picking every sentence someone types that is your business.

FYI: I generally always check with P95 or AOD when trying out new settings. I have no use for the overnight or week long tests though.

My experience says that if settings will pass 5 minutes of either of those tests it is unlikely you would ever have a problem during real usage.

I have found 1 hour occt and 30 ibt runs as a decent test myself. If I can pass both of those I have always tested stable on a 15-20 hour p95 run so I don't even bother with p95 now. But everyone will have their own definition of stable.

Yeah i basically agree along these lines, ill run 30 mins OCCT, or 5-10 passes of ibt, when im chaging clocks, if it passes then i move on to about 8 hours of p95.

P95 needs a bit more voltage then other programs. Heat didn cause crase for sure. One notch up for voltage and im confident it will hold P95. But, im not willing to fry my PSU with more voltage @ 4.4Ghz. I think should hold, but who knows.

My Phenom II 955 died so I was on a single core Sempron 145 for like a month -_- Have a 8120 now at 4.5ghz. Pretty bad chip cuz I need to put 1.5v in bios (vdroops to 1.408 idle and 1.456 under load) but it does the job nicely thumb.gif
