Interestingly, I probably do not really need it with the BE 2400 when considering that I idle at 35W vs Mikael's 56W... And I presume his PSU is actually more efficient than mine. It's probably a combination of a RAM stick less, no WLAN card and more efficient PSU (yes, your PSU is actually more ef...

I tend to see the baseline as being with Speedstep/CnQ enabled, the next level is with software undervolting and the final level is with BIOS under-volting. That wouldn’t add another stage to your testing either but bring it more into line with real world scenarios as commercial systems tend to s...

Interesting review. 8) Why did you choose to test with Speedstep & CnQ disabled? It seems an odd choice for a test looking at power consumption. Personal interest/habit, really. I always have them disabled, for the simple reason that they make so little difference compared to having the system run ...

I returned the board today for a refund, so I can't answer your questions, sorry. The board has a 4-pin connector for the CPU fan, but I don't know how the fan control function is affected by the use of a 3-pin vs a 4-pin fan. I probably should have tested the fan control function, but since I never...

Mikael/Mariner, I think it's OK for the NB to get hot when doing heavy video decoding as the work is now off loaded from the CPU to the IGP, so long as it doesn't cause the system to freeze or show video artifacts due to overheating.

There is probably little reason to have EIST activated on an undervolted E8400, since the power savings would likely be very small. I'd just fix the CPU frequency to the stock 3GHz and try to get the voltage down to ~1.0V (which is definitely a possible target) using the BIOS setting.
