I "disable speedstepping" but it's still here

[hunkeelin]

I went on bios in RIVE and disable speedstep in the cpu power configuration. but when i open cpuz it's still speed stepping (1.2Ghz -> 3.6Ghz.)

 

[ThatsABigOne]

Not again.

[T_Yamamoto]

Lol.

 

[amenx]

There is no reason to disable speedstep. All that you've read in OC'ing guides that it will help your OC or improve performance is false. I hope Intel remove the disable option once and for all.

This. All it does is lower the CPU's efficiency at idle.

So nobody actually can answer the question? Is the speedstep toggle in the bios just a dummy option that does nothing?

 

[Diogenes2]

If turning it off doesn't work there are two possibilities.

1. It doesn't work.
2. It hasn't actually been turned off.

What other help do you think might be offered?


One has to wonder where the OP is getting advice that it should be turned off, then posting here when it doesn't work..

 

[Rvenger]

Thats because C1E and/or Cstates are enabled I bet. If you disable Speedstep, you have to disable all the other power saving options as well. They throttle CPU/Voltage on a hardware level through the Bios. Speedstep throttles through the software in Windows.

 

[hunkeelin]

thankyou rvenger.

Based on the OP's previous posts its a PICNIC error.

Are you sure? I seem to remember with speedstep disabled a chip will sit at its max frequency all the time even with the Cstates enabled as they do other power saving things but they dont downclock the chip. I could be wrong its been a while since i messed with those settings.

I am positive. Cstates and C1E are designed to work in other application environments other than Windows, or older versions of Windows that don't support speedstep.

I'm using a Dell E1705 and I've been trying to figure this problem out for at least 6 months if not longer, but after paying attention to a little detail I skipped I've worked my problem out. I too disabled Speedstep in BIOS. What I found was my t7600 never actually hitting even 1GHZ when it is rated 2.33GHZ. The fans didn't turn on and it doesn't get hot. After looking at this thread I decided to give the BIOS another check for the 100th time. I read the description of the Speedstep states and found the trick:

"Off: Put the computer in it's lowest power state..."etc.

I don't know how I had passed that up all this time, the info I was looking for was in the very first part of the description for off settings! I turned it off and now I'm at 2.33 GHz, my legs are pulling all kinds of heat out the bottom of the chassis, and the fan is on!

 

[Red Hawk]

None of which is really a good thing. The only thing you'll accomplish is wearing out your fan faster and maybe wearing out the CPU faster.

 

[Vaz]

It's been going for 5 years. We all know computers get hot. Every computer I've had gets hot and spins a fan to cool off, so my point in mentioning the heat is that when you have a computer that is normally hot and the fan is on a lot, it's strange when it becomes passively cooled.

I have a Dell Inspiron 1720, which has Speedstep.

If I disable it, it says that is will be running in the lowest speed.

I did this and the whole system was worthless.

So, I re-enabled it.

My problem is the Inspiron is used solely for my home recording studio and it was always dropping out or I had pops and clicks.

I installed some SW called LatencyMon and DPC Checker and they indicated that I needed to disable the CPU throttling. I tried this in the BIOS and of course in the Advanced Power Management. I checked my fan and it is spotless and working. I added some feet to elevate the laptop off of the table to increase air flow and I might buy a laptop cooling device, which is just a fancy laptop holder with fans that you can place wherever to optimize cooling.

What I really want to know is: "Is there anyway to get full CPU usage without throttling so that I no longer suffer from dropouts?"

Or,

"Is there any SW out there that will allow me to override Speedstep, or overclock or anything that will allow me to get the usage of me T9300 2.5Ghz Intel Duo Core Processor?"

Thank you.

 

[Ketchup]

Dells are notorious for not using the best cooling. Speed step is probably set this way so that the laptop won't overheat. Just a guess though.

 

[holden j caufield]

get throttlestop, disable eist and c states. Also you can undervolt (most cpu run max speed with less voltage fine). No dpc latency issues and not heat issues if you undervolt. gl

 

[TremoJem]

So I tried everything before I downloaded CPU-Z or Throttlestop. After changing to 100% in the Advanced Power Schemes I still failed on LatMon and DPC. I downloaded CPU-Z and it displayed constant high levels of CPU performance. Then I downloaded Throttlestop and after setting it up it only made tighter tolerances of the CPU performance and then both programs were sort of locked in. But, LatMon and DPC still fail horribly. So, what does this mean? The whole purpose of this exercise is to optimize the CPU for home recording using Sonar. I am lost now.

 

[TremoJem]

Just as a reference, my setting for the multiplier is 13.5 and both programs display 12.5 with a FSB of 199.5 which has both programs displaying a current CPU performance of 2493.8.

You have to also disable C1E , turn off speedstep and you should be good to go. gl

 

[TremoJem]

So I messed around with Throttlestop and monitored it for a few hours and it does not appear to be doing anything. For example, anytime I check the CPU monitor on Reliability Performance Monitor or the CPU Monitor on Task Manager, they both say I am idling. If I grab an application and minimize the screen size from full to smaller and then move that window around the screen quickly you can see the CPU value increase and so does the graph for those monitors, which is pretty much the same as when I did this in LatMon or DPC and invoked a red spike.

As an observation, If I go into to Advanced Power Settings and change from Performance to Battery Power, then my readings drop from 2.5 to about 1.5. So I guess that setting works. Maybe I should not rely on Windows measuring tools to get a idea of how much the CPU is idle or not.

I just want LatMon and DPC to tell me all my efforts have fixed my problem, but I guess this is not possible. Apparently it is working and I don't need Throttlestop.

So why do I still get epic failures with LatMon and DPC?

What am I doing wrong?

 

[holden j caufield]

get cpuid and throttlestop. Put throttlestop at one set speed, check cpuid to make sure the cpu is not hunting up and down speed wise. DPC latency can be many things, one of the most common is wifi drivers and network drivers, disable both then start disabling some usb hubs and see, each computer is different. My guess is a network driver, go to device manager and disable all network adapters and see if that fixes dpc lantency.

 

[TremoJem]

Thanks, and yes, I did disable all network drivers.

Disabling USB hubs is a total mystery to me. I do not know what to disable.

I have both, CPU-Z and Throttlestop. They both provide detailed information about my CPU and they are aligned perfectly with that information, so I know I have stopped my CPU from hunting.

I was able to get the CPU to stop hunting by changes I made a long time ago in the Advanced Power Management settings. CPU-Z and Throttlestop confirm this. I was confused by Task Manager and Performance and Reliability Manager, as they were not giving my the information I was looking for and I do not know how to extract that information, so I rely on CPU-Z and Throttlestop, which both indicate that my 2.5 Ghz processor is running at 2.499 Ghz steadily.

So my next step is to understand USB hubs or other devices I can disable.

I am ready to wipe the drive and use Win7 32 Bit to see if this helps.

 

[holden j caufield]

if you go to device manager at the bottom is usb hubs, disable them. I would google dpc latency tips or fixes and they can tell you more. good luck. Maybe try a different video driver, if you open/close a screen on a laptop the dpc will also jump.
