Overclocking, my current results.

That'll teach my skim reading skillz!

cpuburn is the only one I've heard of, never used it though You could always loop a kernel compile too - that'll beat a CPU down.

burnP6 got the core temps up to 55 in short order (though a fair bit of sunshine contributed significantly as well). Still plenty of headroom though.

Just for completeness, memtest after nearly 11 hours..

The reason I ask is because most software that doesn't know about this reads the junction temperature, which is typically 10-15C lower than the core temperature.

To give you an idea, my stock E6600 has Tjunc of 34C, TcoreA of 45C, and TcoreB of 44C. It's not particularly critical though as I believe these chips are rated well into the 70s, if not 80s.

PS - recent versions of SpeedFan seem to know about the core sensors.

Interesting..

Both Speedfan and Everest report the single CPU temp sensor (I assume the junction) a few degrees above the core temps. Which is opposite to what I'd expect, but running Orthos with Speedfan running, I'm getting two readouts that are around 50 each (varying up and down a bit separately) and one that's 7C higher and ties up with the readout from GigaByte's own EasyTune5.

But they're all reasonable anyway *shrug*

Bit weird that both Orthos & memtest are showing your CPU speed at 4Ghz.

[Feek]

They're reporting what the speed would be if I'd not dropped the multiplier to 7.

CPU-Z is showing it correctly.

[Toby]

Ah right.

My first overclock...

I got mine up to 9z320 (2.88GHz) in double quick time (lowered the RAM multiplier from 3.0 to 2.5 to keep it at 800Mhz). Only problem was I forgot to disable the automatic voltage tweaks done by the BIOS, so everything got a shot of volts (just a bit too much, as it turned out, but no harm done). Dropped it back to stock volts and temps are now back pretty much where they were before I started.

I'm sure I can get more if I want to, but not sure if I do.

Beyond a certain point, the law of diminishing returns kicks in. Mine is happy at 3.6Ghz but to go any further requires major voltage hikes and thus more heat and noisier cooling which I don't consider worth the effort.
