I test in 5 stages when overclocking
1. Boot?
2. Can it do 30 minutes of RealBench with all RAM?
3. Can it do Prime for 30 minutes?
4. Any issues in long gaming sessions?
5. 4 hours of RealBench and Prime
Stage 1 and 2 are used when testing and getting to Overclock goal area
Stage 2, 3 and 4 are used to fine tune the Overclock
Stage 5 is basically signing it off, sometimes bumping the volts up a notch.
Thanks for this.
Last night I ran 7 hours of AID64, although I don't find AIDA stress test tough enough to prove true stability, and that was proven this morning, I ran 100 passes of IBT with standard settings, it flew though, however, I then went to 20 passes of maximum settings on IBT and it kept crashing, I'm not completely satisfied it was the CPU causing this though, I have a suspicious feeling its the VRMs, sometimes it would reboot, sometimes just completely power off, adjusted it by dropping the clock to 3.9ghz and the voltages a bit, finally got through 50 passes of IBT on max settings, max memory, its now running realbench for the last 4 hours, but before I goto bed tonight, i'll fire up prime95, if its gets through all of that then i'll be happy.
My CPU will do 4ghz, but at 3.9ghz I barely need any voltage increase, just +0.180 to the cpu core voltage, everything else is on normal, however to get 4ghz, an extra 100mhz more, I need stupid amounts of voltage, just not worth the extra heat / extra voltage etc for only 100mhz more.
