• i5 3320M not using TurboBoost
    16 replies, posted
So I've got a laptop with the Intel i5 3320M CPU. According to specs the CPU is clocked at 2.6GHz with max speeds of 3,3GHz using intel TurboBoost. Yet during gaming I've noticed the CPU doesn't automaticly clock to 3,3 GHz, Instead it just stays at 2.6. I've checked the bios to see if it's enabled and it was, I've also installed all the drivers for the laptop from the DELL site but the issue is still there. Also when I tried installing Intel TurboBoost monitor it said that my CPU didn't support TurboBoost (Which is weird) Anyone have any idea what could be causing this and how I could fix this issue? [editline]14th October 2012[/editline] So I've enabled intel speedstep which is responsible for downclocking in order to save power and from what I understand TurboBoost ONLY works when SpeedStep is also enabled. So I've enabled that. But now my CPU is clocked at about 900MHz, Even when running Prime95 it just stays at 900MHz.

And when I launch it it says that it's in eco mode but I don't see any button on the UI to change it. [img]http://i.imgur.com/JykaC.png[/img] "Energybesparing" means energy saving mode.
Turn off energy saving mode in the windows control panel.
[QUOTE=GREN EYGS N HAM;38032739]Turn off energy saving mode in the windows control panel.[/QUOTE] I did. Now something stange is going on, I've set the Intel Turboboost service to automaticly start with Windows. And now the CPU is automaticly overclocking when needed (To 3,3GHz) But here's the thing.... It only does that when the AC adapter is UNPLUGGED. As soon as I put the AC adapter back it in goes back to energy saving mode... [editline]14th October 2012[/editline] [img]http://i.imgur.com/duCT7.png[/img] This is the CPU when stressed with the AC adapter unplugged, So only on battery.
Maybe you fucked your power setting up. Do you have it on 'Balanced'?
No, This is a fresh windows installation. The energy sheme is set on maximum performance. I've even checked the advanced settings for the profile itself and in there everything is set on max performance. [img]http://i.imgur.com/jKHA0.png[/img]
Have you tried using ThrottleStop?
Enable EIST/SpeedStep in BIOS. Edit: reset your bios settings to the defaults
Already tried all that, Nothing yet.
Try setting the maximum speed to 99 or 95%

Oh man I LOVE you. It's clocked at 3.1Ghz now during gaming. Thus making games more fluent. Do I need to run this program each time I want to game? [editline]14th October 2012[/editline] P.S. It's now clocked at 3.1GHz while the specs say the max turbo is 3.3GHz. Would it be possible to push it from 3.1 to 3.3?

Turboboost will never hit max with all of the cores pushed (The initial idea of turbo boost was to make use of the cooling capacity of the cooler when a single threaded program was pushing one core but not the other). Some motherboards have a function in the BIOS that allows the turbo to run at max bins all the time, but you won't find that on a laptop. In more detail: (I don't know anything that anyone else doesn't, but this is how I think it is from experience): -The CPU can boost upto 2or3 below it's turbo multiplier limit with all cores loaded if it is within Temperature AND Power Draw - 31 x100 in your case -The CPU will hit max turbo multiplier only when it is within its TDP AND not all of the cores are loaded. - 33x100 in your case
Ah I see, Thanks for the info. I also found the source of the problem, After digging in the bios I found a logfile which indicated that the current AC adapter I use isn't sufficient. I'm using a 130W adapter now while I need a 210-230W adapter. So I'll have to buy one of those sometime soon. The log said it would decrease performance to compensate for the underpowering AC adapter so I'm guessing that was the source of the problem.

Throttlestop will stop the performance compensation, but make sure your battery is either: a) fully charged or b) removed from the laptop whilst you are using it. If it's trying to charge the battery and it can't supply enough power to the system bad things may happen. What graphics card do you have? I have a i5-3110m and overclocked 650m and I don't seem to have any problems on my 130w PSU (Clevo). Given it is Dell, I would half suspect them of putting the limit in to make you buy a new PSU. They shouldn't be shipping the system with a CPU that can't power the system if it's all stock.
Yeah the adapter I'm using ATM isn't the one that came stock with it. I've got an AMD FirePro M6000 GPU. Gaming wise I don't know how well it does. I seems the CPU is the one bottlenecking at games like BF3. For example I can play BF3 @ high+1080p at about 30-40FPS. (When my CPU is at 3.1Ghz) When my CPU was still at stock 2.6Ghz I'd get like 20-30FPS.
[QUOTE=Djessey;38037792]Yeah the adapter I'm using ATM isn't the one that came stock with it. [/QUOTE] Ah it's understandable then. Unlike most laptops, Dells PSUs actually have a sensor pin to let the computer know what the PSU is. This is why you see so little non-dell replacements PSU's about. Some Dell laptops refuse to charge entirely and throttle the processor with a non-Dell PSU plugged in, even if the PSU can support the laptop.
Yeah I'm not using a fake adapter or anything. Simply a DELL AC adapter from an older (dell) laptop.
