    Thanks Apollo13. Glad to hear that you've got this tweak working. It's not a huge increase in performance but it's free. If you manually enable EIST, you can set the core voltage to something reasonable before doing the Dual IDA trick. Then you get the best of both worlds, more MHz and low voltage.

    The X7800 price is nice. I think a stable 3.2 GHz to 3.4 GHz might be possible with one of these. At that speed, I'd probably prefer using it on a desk and not on my lap but other than that, it might give your laptop a new life. :)

    I have an E4300 with the same SP9400 and just noted during some Everest benchmarks that the multiplier spiked from 9 to 9.5 (for 2.57 GHz, about 5% overclock). It's just one core, of course, as shown:

    I'm curious, Dillio187, when you say it "works great" how do you have yours set up and what result(s) you're getting? Was hoping to get that little extra *umph* from this otherwise awesome laptop (got lucky and snagged one for $200).

    Thanks...

    Go to the first post in this thread. It shows you how to lock Intel Dynamic Acceleration so both cores of an SP9400 are operating at the 9.5 multiplier.

    If your bios allows you to toggle EIST/SpeedStep, you can use ThrottleStop to do this.

    ThrottleStop is also very accurate at reporting when IDA mode is being used. Run a single thread of Prime95 and use the Task Manager Set Affinity... to lock it to a single core so the second core can spend most of its time in the C3/C6 sleep state and the primary core can spend most of its time using the IDA multiplier.

    When Dual IDA mode is enabled, you will be able to run 2 threads of Prime95 with both cores locked at 9.5.

    Yah, I did that earlier, funny thing was that even when I disabled ThrottleStop it "stuck" - even across a reboot it was still going at the 9.5x multiplier. :) Not a good thing on battery but I resolved it.

    I was merely asking that other person to post how he'd done it, I already got the same results (I'm sure of).

    Another funny thing is that I can't find anything from Intel that verifies the SP9400 supports IDA but, there is it, 9.5x. It's not much - at the stock speed of 2.4 GHz and 9x multiplier I had wPrime at 38 and some odd milliseconds; at 2.527 GHz it was 36 and some more odd milliseconds. :)

    Something is better than nothing, I suppose.

    Here's some Intel documentation that confirms the 9.5 IDA multiplier for the SP9400. (9.5 x 266 ~ 2533 MHz)

    [​IMG]

    When you run CPU-Z, by default it is only showing you one core so when it shows 9.5, that may be misleading because it doesn't show you what the other core is doing. Some users think they are in Dual IDA when really they aren't. If you rebooted then it would have been impossible to be in Dual IDA unless you used a program that allowed you to disable EIST from within Windows. That's the only way to lock both cores.

    On my T8100 it goes from 10.5 to 11.5 so the percentage gain is better than going from 9.0 to 9.5. In your case, the percentage increase is so minor that I'm not sure why Intel went to the hassle of creating this feature. I think the marketing department must have won that decision.

    When using Dual IDA, you can set core voltage to a lower number so it won't significantly reduce battery life. At idle, the 45nm CPUs use a low voltage sleep state regardless of how ThrottleStop is set up. Using a high multiplier allows the CPU to process information faster so it can enter and spend more time in the more energy efficient C3/C6 sleep state. That explains why Intel got rid of Super Low Frequency Mode in the newer Core i CPUs. It's pointless.

    @unclewebb:
    With my Latitude D830 + T9500 in Win XP ThrottleStop works perfect. I let TS run automatically at start up by the Startmenu option. It works great and runs immediately @ 2.8GHz.

    In Windows 7, on the same laptop, it doesn't work that way. I can make TS run at start up, but it shows it's running @ 1.2GHz. :eek:
    I can make it run @ 2.GHz by hand, but after a restart it's back to 1.2GHz again.

    Am I missing something? Cause in WinXP it's not an Issue.

    This sounds like a timing issue where one operating system loads ThrottleStop and starts running it quicker. Maybe too quick. When TS checks to see if DualIDA is engaged or not it might not be correctly determining that.

    In Windows 7 you could try starting ThrottleStop up using the Task Scheduler method. W7 might handle the WinRing0 driver slightly differently so startup is delayed or is faster compared to XP. I'm not sure.

    Here's the task scheduler method:

    Task Scheduler Start Up

    I'll do some more testing of this to see what I can figure out.

    I added some system tray pop up info to ThrottleStop 2.71 so it will be easier to check if Dual IDA engaged correctly or not. I also noticed this bug sometimes when resuming from hibernate but it would work correctly when resuming from stand by in W7.

    2.71 includes a few changes to improve the chance of getting Dual IDA mode locked at start up. Let me know ernstig01 if this improves things for you. Time to go do some more testing.

    Edit: I find the simple start up folder works better than the Task Scheduler. Both methods work but the start up folder method seems to enter Dual IDA mode much quicker. The CPU has to be fairly idle for it to enter Dual IDA so if you have a lot of startup junk, it can take a while before the CPU is idle enough to go into Dual IDA and lock both multipliers.

    Edit#2: I think there is still room for improvement so I'll be making some changes to try to improve this feature further.

    Well i have hp dv5t with p8400.In bios there is no option of speedstep.only there is option of enabling or disabling C6 sleep state.
    So i guess i am out of luck.
    can i undervolt cpu with throttlestop on my laptop?

    hmmm... so when i set the multiplier to 8.5 on my q9000 (with EIST checked and not uncheckable aka still locked in BIOS), it seems that all of the cores stay at that (they definitely go above 7.5, which is the default max)

    Can you post a screen shot of ThrottleStop? With regular Intel Dynamic Acceleration, the 4 cores can average more than the default multiplier, especially at idle, as IDA rapidly cycles on and off as the load varies and cores enter and exit the C3/C6 sleep state. When all 4 cores are fully loaded running Prime 95 or a similar stress program like wPrime, you are limited to your default multiplier when EIST is enabled.

    When you can disable EIST, then the CPU can lock the multiplier so each core can use the IDA multiplier, even when fully loaded. Check the picture in the first post of this on a T8100. Default multi is 10.5 and the IDA multi is 11.5. I don't think the HP BIOS lets you unlock EIST so you can't take advantage of this trick.

    Check out my signature. I've been waiting to get some feedback but that takes forever. I've decided that it's less confusing to just release new versions and wait for the complaints to come in when I screw something up.

    I get feedback much quicker when something doesn't work. :)

    Edit: Version 2.72 has another tweak or two so Dual IDA mode should work more reliably when booting up.

    TS 2.72 performs a lot better under Windows 7.
    I tested TS coming out of hibernate mode and also stand by mode. TS starts with multiplier 13.0x and after a few seconds it's running 14.0x just perfect now.

    Again, thanks a lot for this great tool.

    If the bios has locked the EIST/SpeedStep bit then there is nothing you can do to get Dual IDA working. :(

    Most Dells seem to leave this unlocked so you can toggle it while most HP laptops have the EIST bit locked. When it has been locked by the bios, there is no way to unlock it when you are in Windows.

    Worked like a charm with Vostro 1500 and a T9300. I also took the time to undervolt it to 1.1v, which would probably improve temp & battery life than if I were letting the mobo automatically crank it up to 1.35v at the fastest clock.

    I didn't do any sort of 'proper' stressing, but I did play a whole 2 hour of Company of Heroes, and there wasn't any problems there :). All in all, can't say there's anything wrong with getting a bonus 200Mhz for "free" ;).

    Thanks a bunch, unclewebb!

    EDIT: One thing I noticed is that it seems like the Fan no longer goes to the slowest spin-cycle, despite the fact that the temp gains are not that much (from 38C to approximately 41C idle). Hmm, weird.

    EDIT #2: Nevermind, the fan does cycle down to the slowest speed, but a new problem creeped up that's even more annoying: Anytime I run a program that requires loading a large amount of info into the RAM (or unload it, when I close it), for example a game or a video file, there will be a huge pause as the CPU usage on both core shoots up to 100% usage, and the computer is literally unresponsive for upwards of 15-30 seconds (mouse won't move, keybord "numlock" won't change states, etc). Clearly this isn't normal... any ideas?

    I've been using Dual IDA on my T8100 for a while now without any problems like that or any problems at all. Moving a file from the hard disk to the memory in not a CPU intensive task so something else is loading your system when that happens or you have a hard drive getting ready to die. Have a look at task manager and see what it shows is using up your CPU cycles.

    I disabled the option in Bios and once it rebooted a message saying Windows could not boot appeared. A repair wizard solve the problem and i opened throttlestop.

    However before I could do anything the system freezed.

    Anyone experiencing similar problems ?

    Thanks!

    EDIT: Anyone i shall give it a try when I get back home.

    Reading.. I ned to add DualIda 1 to the .ini? Does that work anymore? (page 1).

    Also, did you solve the suspend/hibernate problem?

    Thanks in advance

    EDIT2: Also on page 3 it is stated that this software is not compatible with RMClock (I'm undervolting).

    Is it still correct?

    Thanks

    It's OK to run ThrottleStop and RMClock at the same time but only use one of these programs to control your multiplier and VID settings. If you use both of these programs to control FID/VID then they will fight against each other over control of your CPU. You don't want that.

    You can use ThrottleStop to reduce your core voltage too.

    Make sure Dual IDA mode works on your laptop before using the DuaIDA=1 INI file option. If your laptop can not boot up reliably with EIST disabled in the bios then I don't recommend trying the Dual IDA option. A computer should be able to boot up and run without locking up whether EIST is enabled or disabled.

    Dual IDA should get correctly restored after you resume from hibernate or if you resume from stand by mode. If you are using RMClock to manage your voltage, you won't be able to use Dual IDA mode. The two are not compatible. Dual IDA locks both cores of your CPU to a single multiplier and to a single voltage.

    That will require ThrottleStop to be running in the background via the tray, correct?

    To restore Dual IDA mode after you resume from sleep mode, ThrottleStop needs to be running. When minimized to the system tray, it can run for hours while consuming next to nothing in CPU resources so you don't have to worry that it is going to bog your system down when running like that.

    @unclewebb - On my u7600-1.2 2510P, the the x9 multiplier is 0.9V, the x10 (IDA) is 1.0V. That extra voltage could gives more overclockability. With setfsb I can get a stable 1.6Ghz@x9, but if I switch off a core in the bios and test IDA I can get 2Ghz@x10.

    Now only problem is the bios has locked down the Speedstep/EIST bit so I don't get dual-IDA. So the CPU switches to [email protected] when both cores are activated where i am once again limited to 1.6Ghz (0.9V). The possibility of an extra 300-400Mhz is tempting to try to figure out.

    Would you know what the likely code is to lock speedstep so that Throttlestop can't enable dual-IDA mode? I'd like to go digging through the bios code.

    One user successfully got Dual IDA mode working on his laptop (OCZ I think) by going into the bios and doing a tweak.

    The lock bit is in MSR 0x1A0 and is bit[20]. This info is in the Intel Manuals, Volume 3B. If you can find the wrmsr code for that register and are able to turn off the lock bit then you are set. Bit[16] is the flag to show when EIST is enabled or not but it can only be changed when the bit[20] lock is cleared. After you change that one bit then the bios would likely need a new checksum as well so it would work. This is beyond what I know how to do but it is certainly possible and has already been done by one user. Post here if you get this working on your laptop. I like hearing about success stories.

    Modifying the bios to unlock MSR 0x1A0 bit[20]

    Analysis which can be applied to other notebooks on how to do this is here. The 2510P uses some form of anti-tamper decompression on startup making the bios mod more painful.

    I have read up on this program and am wanting to try it

    after downloading I tried to start the program and I get an error stating "Could not open WinRing0.dll"

    After further research I found a reply stating that it could be in use by other programs and not allowing access. Unfortunately I have systematically closed programs to try to find any other program using this driver and nothing has worked.

    Any other advice would be appreciated because I would love to see how this works on my laptop

    thanks

    Are you in an account with Administrator privileges? You need that for this program to work.

    After a clean install of Windows, I know ThrottleStop runs OK. Some other program that uses this open source driver might have left some junk in the registry. One user had to go through his registry from one end to the other and delete all references to WinRing0. After that, he rebooted and ThrottleStop ran fine. The only other thing I can think of is an over zealous antivirus or anti-spyware type program blocking this driver from being installed.

    Very interesting to hear about turning the EIST lock bit off with a simple bios mod to get this trick working on more laptops.

    I am on an admin account, and I have tried running the program as admin. I also have tried it with my antivirus and anti-spyware off.

    I guess I will try going through my registry and delete any reference to it. Though I haven't found any programs that use it and I just recently cleaned and defragged my registry

    Make sure you unzip all the files in the download to the same folder. There was one antivirus program that used to complain about the WinRing0.dll but I haven't heard of any issues recently.

    omg... finally a good program.
    I've been using:

    CrystalCPU
    RightMark
    CPUGenie..

    they all sucks and outdated = unstable.


    ThrottleStop is excellent.


    I'm on HDX16 with E8435 CPU. If I have BD PROCHOT unchecked = disable? What is the use of it exactly? I have read the help/manual but still don't get it.

    BD PROCHOT stands for bi-directional PROCHOT. Does that make sense? Of course not. :)

    PROCHOT is Intel speak for processor hot. Typically the PROCHOT signal only gets turned on when the processor is actually hot. Some motherboard bios versions decide to tell the processor that it is hot for a variety of reasons, which forces it to start throttling which slows it down, before the processor is officially hot according to the Intel specifications. To disable this method of communication and this type of throttling you would need to un-check this option so the BD PROCHOT box is clear. I put a lock feature on this in the Options... window to discourage people that don't know what they are doing from turning this off. I was originally trying to play it safe but I can't see any reason to have this checked.

    When this feature is turned off, the CPU is still quite capable of taking care of itself and throttling itself and slowing down if it ever does get too hot so there shouldn't be any problems.

    My laptop and desktop don't use this throttling method but I believe some HP and Asus laptops do. I haven't got much feedback about this feature so if you learn anything new, let me know.

    By the way, go Habs go! I'm not looking forward to the new season seeing as though they gave their goalie away. I've never had a lot of confidence in Price but that's a topic for another forum. :D

    I tried to add support for some of these early Core processors but I don't have any hardware to test with and zero feedback so I have no idea what works and what doesn't.

    It sounds like ThrottleStop starts up for you. If it does start up, what does it display? Does anything seem to work? Is there something that definitely doesn't work? Show me a screen shot of that and CPU-Z so I can try and figure out what's going on.

    Some processors like the original Atom processors don't have the necessary internal high performance timers that ThrottleStop uses so I imagine that would cause a lot of unknown problems and might lead to some divide by zero errors and other strange things to happen. I might be able to come up with a few fixes to disable some of the features to try and get the basics working for you. Show me a few more details. Maybe a screen shot with the multiplier and VID adjusters at their max and min and include CPU-Z so I can see if this is controlling the CPU at all, even if some of the data it reports is out to lunch.

    Sure thing, happy to help out as much as I can.

    When I start TS, it can't read the FID or CPU load. It seems to read the temp alrighty.

    Here's a screencap of ThrottleStop and CPUZ running at the same time.

    If I enable ThrottleStop, my PC locks instantly. I assume because of the VID being "read" as 0.

    As I thought, your T2500 doesn't use the internal timers that most of the newer CPUs use. I might be able to come up with a fix for this.

    The important thing is the voltage ID. When you click on the ThrottleStop adjuster for Voltage ID, what is the minimum and maximum it shows? It's presently showing 0.7125 which is usually a sign that this is not working at all. If this isn't working then I might have to get you to read a couple of registers within your CPU for me. You can use my MSR Tool for that purpose.

    http://www.fileden.com/files/2008/3/3/1794507/MSR.zip

    Go to the MSR Number box at the bottom of this tool and enter

    0xCE
    0x198

    and then click on the Read MSR button after each one and take a screen shot of that and post it so I can have a look. You can run two instances of MSR Tool if you want so then you will only need to do one screen shot showing the contents of both registers.

    Once I see that info I will see if I can make some improvements to correctly support these early Core Duo CPUs.

    The shown voltage ID I can't adjust in TS. It's stuck at 0.7125

    Screenshot as requested :)

    This is just my work laptop, so please don't spend much time on this if no one else is asking for it. I was more curious than anything. Happy to help you get it to work though if it's something you want to do!

    Those screen shots show me what the problem is. Hopefully with a few minor tweaks I can at least get the VID working more or less correctly. The minimum and maximum VID are not being read correctly so that's why it's locking up. When you try to enable it, TS sets the VID as low as possible which combined with the 12 multi gets you an instant crash or lock up. I won't kill myself but I'll see what I can do to at least get ThrottleStop working a little better with this CPU. I have a plan. :)

    Edit: Initial testing looks promising. If anyone else has an older CPU then send me a PM.

    I finally got the program working, and got my BIOS password from Dell so I could disable Speedstep

    Unfortunately, I can't seem to increase my multiplier past the default 12 and therefor unable to overclock at all, but I can lower my VID. Am I doing something wrong or is it just not possible for me to do it?

    I have a T7200 in a Dell Inspiron E1705 btw

    See unclewebb's signature for latest version of Throttlestop
    Introduction

    An EIST-unlocked bios will provide a full multipler (or half for 1066Mhz FSB P8xxx or T9xxx cpus) , gaining 4-17% more CPU performance on any IDA-capable Core 2 Duo/Quad CPU when using Throttlestop. Examples shown on the right. Throttlestop also extends the highest voltage range available which is handy for greater setfsb overclockability and decreases the lowest voltage available for undervolted battery life improvements. Combining dual/quad-IDA and PLL overclocking will give the greatest possible overclocking.

    Originally this thread only had Dell/Alienware dual-IDA C2D success stories. Now there is quite a few modded bioses below which allow the system to be dual-IDA overclocked.
    .
    Example of dual-IDA clocked C2D CPUs​
    SU9300-1.20 -> 1.40@x7

    Other notes


    • dual-IDA can be enabled on Linux as described

    • T4xxx/T6xxx/SU4100/SU7300 CPUs have no IDA support

    • Appears all other systems except Dell/Alienware have EIST locked down, so require a modded bios.

    • The 2510P's u7600 was single-IDA capable even prior to applying the modded bios however it was inactive. It required TS to activate IDA. Running TS in the background will maintain single-IDA as will exiting TS *only* if using a High Performance profile with minimum CPU set to 100%. Single-IDA increased the 2510P's Win7 WEI by 0.2 points as shown here.

    All that work getting ThrottleStop working StaFForD and now I have to tell you that the T7200 does not support IDA mode. :(

    Thanks for the hard work nando4. I added a link to your post to the first post in this thread to help other users. I think many of the Alienware laptops also support adjustable EIST and Dual IDA mode.

    Sorry, feel free to move it ;)
    Read something about 'post your experiences on your xx setup here!'.

    Tested the 3,6 on half an hour of stress with the standard voltage without probs, so I guess she wants more..

    Btw: somehow wired that now, when everyones wants the newer cpus, these ways are figured out how to nearly oc every c2d...........

    sorry, just noticed this reply (haven't been tracking this thread a ton)

    As you've discovered, that is how I am running it, with UAC disabled in Windows 7. I just updated to 2.85 and it seems a little less quirky. I also have my VID voltage turned down to 1.1 for a little cooler running.

    Thanks kevin ;) this thing worked out perfectly on my Dell XPS M1330. Its got a T7300 if that matters.

    Will be using this on other lappies :p

    Finally spent some quality time with the program. Thanks to unclewebb for his pointers along the way. I've previously been undervolting with RM Clock which does nothing with the IDA 9.5x FID so my computer wasn't ever running on it. I did some wPrime testing (five 32m runs) with Throttlestop set up like in the first post of this thread, then with my old RM Clock settings and then using neither of these, just Windows power management.

    Throttlestop was of course, noticeably quicker.
    [​IMG]

    The times for each run were
    1. 33.917 seconds
    2. 33.678
    3. 33.817
    4. 33.566
    5. 33.459

    [​IMG]

    1. 35.584 seconds
    2. 35.769
    3. 35.583
    4. 35.429
    5. 35.475

    And then the Windows times were

    1. 36.863
    2. 35.769
    3. 36.116
    4. 36.630
    5. 35.880


    On battery only, I noticed that Battery Bar has gone from an estimate of 2 hours 50 minutes to 2h 57m but since today has dropped down to 2h54m. Unfortunately, it seems like there's not much out there for measuring consumed cpu voltage but Battery Bar does have a discharge rate so seems that's the best I can get for now. I've noticed that it's gone up a little from using RMClock but that's a huge variable and I've not paid too much attention to it as of now.

    I'll keep a close eye on the discharge rate though and do some more testing. I'm really interested in how much power TS allows the CPU to use at full dual IDA w/ the processor usage in the ~10% area vs RM Clock's 6x FID SLFM.

    Other than task scheduler, is there a way to get TS to start up at logon? There must be some kind of registry addition but I'm not sure exactly.
