Speedstep will not decrease multiplier

[S_Coban]

Hello all. I noticed that intelspeedstep is not decreasing multiplier to x16 on idle anymore. It used to be doing that, but today when I was monitoring temps, I saw that cpu multipliers are at x45 at all times. Enhanced Speed Step is enabled in bios, also all C states are on Auto. I am using High power settings in both AI suite and Win 7. Overclocked to 4.5, using offset vcores. I tried to use balanced or power saving settings within windows and ai suite, but no avail. What might cause Speedstep to act like this ?

Also, there is another issue, I am experincing. It is not very important but if anyone has an advice for that. Updated BIOS to 1101, but still can not use USB mouse in BIOS. 😞

Cheers.

my rig : Win 7 x64 - Asus P8Z68-V Pro - i5 2500K 4.5ghz - CoolerMaster V10 - Asus GTX 560 Ti 1gb - Corsair XMS3 8gb CAS 9 - CoolerMaster HAF 932 - Corsair TX950w - Corsair Force 3 SSD 120gb

Either set your power profile to balanced performance under OS, or set your C-State to Enabled rather than Auto, then it should work.

Which mouse are you using by the way?

Setting C-States to Enabled did the trick. Thanks. Now multiplier at x16 on IDLE. However, now I can not use Vcore Offset value manually. I have to set it AUTO, otherwise I get BSOD. I tried " - '' and '' + '' modes, and different values, from 0.005 to 0.020. In AUTO mode, for 4.5ghz, '' + '' mode, gives me max 1.37 vcore, and temps around 75 degree on full load. If I could set it manually, I was able to be stable with 1.35 vcore, and around 73 degree (full load). Right now, LLC set to Medium, PPL is disabled, Phase Control is Optimized, Duty Control is Extreme, CPU current capability %130, VRM frequency 350. Hope someone has got an idea for this 🙂

I am using Microsoft Wireless Laser Mouse 5000 with Microsoft Wireless Desktop Receiver 3.1.

Your power settings in OS will determine how your system interacts with Speedstep - further if background services are still running that will prevent your set-up from being able to drop multiplier. AVS or Microsoft indexing are normally the cause for this as they run in the back ground.

Try the offset value + 0.0350

If default is 1.100 then you will go upto 1.1350 under load at 4.5GHz as it was before. 🙂

Thanks Hivizman. I guess this default value is being changed by LLC settings. LLC = High, I look stable with +0.020. It gives me average 1.35 vcore. I also changed Phase control to Extreme. Everything looks okay now (except mouse issue). Speedstep works fine. Multiplier is at x16, and vcore drops to 1.00 on IDLE. By the way, this AI suite sensors always show wrong temps. It is a bit disappointing that Asus provides a very buggy software for monitoring. Cheers.

UPDATE. Has anyone got an idea why I can not use Negative Offset ? If I even put -0.005, windows will not start.

Problem solved. Cheers.
