I'm hoping to get up to 2.8 or high but want to make sure I keep everything cool enough.
Personally I wouldn't worry too much.
According to many reports I've read, as well as borne out through my own observations, LCB9Es run quite hot compared to older dual-core Opterons. Strangely enough, though, they also seem to require less VCore to maintain stability, even at very high overclocks.
My LCB9E (see thread here
has its IHS removed; it's also running .5V below stock voltage and at a super-steady, go all day long without any crashes 2.8GHz. Even without its IHS, which should have resulted in a dramatic temperature drop, at full load it tops out at around 49 degrees C on a hot day with hot ambient temperatures. I didn't test what the load temperatures were with the IHS on (I just wanted to pop the top off!
), and I regret that because I couldn't measure the effect of removing the IHS, but based on many reports, LCB9Es just run insanely hot.
I've got a theory that is impossible to test without a thermal imaging camera or some other similar apparatus, unfortunately, that many LCB9Es have their temp sensors calibrated to read very hot. Either that, or they're simply engineered to accept super-high temperatures compared to older batches.
I say let other indicators be your gauge. If your system is unstable and is exhibiting weird behavior attributable to overheating (lag, or shutdowns), then that's the best way available to determine what's too hot.
Sorry there's no better way to explain.
