HP 8560w TurboBoost Problems

Thanks for this test, it seems that 13C difference is rather high. Even used by HP SunOn Maglev (high temperature cooler that is used for example in projectors for cooling) is a suggestion that insides will get hot, this cooler has magnetic bearing and when operational it's metal bearing elements do not contact each other. This is only way to build reliable laptop with temperatures reaching 100C (Sunon) .... but this will not apply to HDD's and theirs bearings! If reliability is important I think that HP did deliberately turned this feature off. They are hush about this move as they know that in effect only one 15" mobile workstation would left as choice, I'm not a Dell fan but, it's hard to not admit that M4600 (m6600) only have cooling capacity to hold x4 core i7 and powerfull discrete GPU. Also it seems that it is quite true, due to configurations (with i72920xm CPUs) that are possible only with Dell M4600.

95C is far to close to the point when (after some extensive use) dust will came, thermal compounds will dry and after year whole laptop will shut itself down (as now Samsung RF511 based on 2630qm+GT540m does) due to CPU reaching 105C (of course with Turbo on). It would look far better when maximum CPU temps were in 80 - 85's range with Turbo turned on.

Hi again,

I did further tests, with more comparison, I played 15 min Skyrim with time in-between to let the Notebook cool down to around 60°.

I conducted three tests, one with Multi-22 (original), one with Multi-24 and one with Multi-33. I have all the results in the Excel chart and I also did some graphs to see the difference.

As a result, I have to say, that Multi-33 is as stated by the former poster, on long-term use to risky. The temp is spiking at 100° and 50% of the time the temp is higher than 85°, also the Power usage is increased a lot, also 50% of the time it is more than 25W in comparison to the original setting where 25W is almost max. Safe to say, that Muli-33 should definitely not used for long-term.

As a trade-off the Multi-24 variant seems quite nice, the Power usage is almost the same as the Multi-22 the temp is around 90° instead of around 85°. Also the Multi-24 is reached quite often. So, to give this machine a little bit more power and be safe, a Multi of 24 should be safe.

For more information look at the Excel-Sheet. I will now set the Multi to 24 and will use it for a while

Great info and thanks for sharing!

One feature that ThrottleStop has that might be useful is profile switching based on CPU or GPU temperature. You could set up Profile 1 to use full Turbo Boost and then set up a second profile with Turbo Boost disabled. In the Options window, click on the Alarm box and set it to a DTS value of 15 which will tell it to switch to Profile 2 when it gets to within 15 degrees of the Intel specified throttling point.

The Intel DTS sensor is a count down thermometer so a DTS setting of 15 is approximately equal to a temperature of (100 - 15) or 85C. When your core temperature is under 85C, ThrottleStop will use Profile 1 so your CPU can run at its full Intel intended speed. When the core temperature hits 85C, ThrottleStop will switch to Profile 2 and disable Turbo Boost if that is what you have told ThrottleStop to do. This is a great feature so you can use your computer without worrying about it getting too hot. It will continuously and automatically switch profiles while gaming or whatever you like to do.

Another thing to keep in mind is that a peak core temperature of 80C or 90C is a big number but it is well within the Intel specification. This temperature reading is coming from a microscopic spot located on the hottest part of the core. As soon as you move 1 cm away from this point, the core temperature of a significantly loaded CPU can drop by 20C. If Intel was not comfortable with their CPUs running 24/7 at a peak core temperature of 80C or 90C then they would lower that value.

Don't let your own temperature fears keep you from using your Intel CPU as the manufacturer intended. Intel builds some incredible technology into their CPUs to keep them running within specification no matter what you do with ThrottleStop or any other software for that matter. No software can prevent an Intel CPU from staying at a safe temperature. If an Intel CPU really needs to throttle to reduce the core temperature, it will.

for turboboost to be used you need to ensure the Intel Management Engine is installed and up to date.

and by the by, it states quite clearly in the quickspecs that the cpu's have turbo boost.

Well, I have latest Intel Management Engine Components driver and Intel Full Management Engine (ME) 7.0 Firmware, but Turbo Boost works only with ThrottleStop aid.

Nice find. If HP says this model is supposed to support Turbo Boost and it is not working correctly then HP needs to get to work on a bios update. Owners should not have to hunt through forums and run third party software to get basic features of the 8560w working properly.

indeed, i had a test on a 8560w and it does seem that there is a limitation on turbo boost. (I was not aware of this before posting about the IMEI driver).

I am surprised though, because the fan could quite easily cope with the TB frequencies, so there must be some reason it's disabled (or crippled as we can adjust it with TS)

I've got the same problem on my Elitebook 8460p QM2720 that Turboboost just works with throotlestop on.

Bios F.23 brought back Turbo Boost to the 8760W. I suppose that bios F.22 does the same for the 8560W.
