T61 with T9300 - clock multiplier drops to X4 from X12.5

#1 Post by Hixon » Sat Sep 29, 2018 3:11 pm

Hi all,

I got this T601 Frankenpad w T61 & X3100 mobo (middleton bios) and I always had this issue that under load (especially when playing an old game, or watching HD movie) my cpu clock multiplier drops down to 4X (w 200fsb that goes 800Mhz) from 12.5X (2500Mhz). When this happens I need to stop the game/movie for a couple of minutes to get the clock multiplier up again.
Till this week I thought this has to do something with my weak stock T61 Heatsink. However, I replaced my Heatsink to the 42W2028 yesterday. The swap made an excellent imrovement in temperatures, I got 20C less in idle and 15 less in peak temps. However, the new HS does not seem to help with clock multiplier problem. Has anyone else experienced similar thing w the T9300?

I checked my T9300 and it is not a ES model on anything like that (its a PS slaqg). I also tried to stress my cpu w prime, the multiplier drop does not seem to happen in this case. It feels like its only happening when the X3100 is doing something more heavy but I could be wrong. Any thoughts?

Thanks folks, I would appreciate your help.

Do you have any clue of what the GMA X3100's temperatures are floating around at, while running a game or playing your HD movies? That would be essential to know if it is truly your GMA X3100 that has a problem.

If the GMA X3100 is at fault, download Throttlestop and then untick the box that lies on the left side of 'BD PROCHOT'.

Everest reported 64C for the North Bridge where the X3100 is integrated at the moment when my clock dropped, doesn't seem particularly high to me.

Apparently, the GMA X3100 is not the problem. I think it has something to do with the battery, is your battery genuine or a replica? I have a suspicion that the battery may have not supplied enough power to keep the GMA X3100 and the T9300 fed while running intensive tasks.

Before we can tell that the GMA X3100 has nothing to do with the problem, could you download Throttlestop and set the clock multiplier to 12.5, if the multiplier drops again? Untick 'BD PROCHOT' if it is left ticked too.

Thanks Screamer. I noticed a couple of things while playing with this throttlestop. Unfortunately, when I unticked BD HOTPROC, nothing changed, my clock multiplier dropped the same way (down to 4x). However, when I set a clock multiplier to 12.5(should be the nominal) the throttlestop could overwite this 4X multiplier back to its original one (quite nice). Now I also noticed something else, I read on some other forum that this 4X multipler is just the halved 8X multiplier bacause of the enabled SLFM.
SLFM stands for Super Low Frequency Mode and is an option on many of the Core 2 CPUs. With this enabled, at idle your CPU will reduce the bus speed in half which will reduce your total CPU speed in half. Here's an example of an X9100.

11.5 x 266 MHz = 3059 MHz - HFM, High Frequency Mode
6.0 x 266 MHz = 1596 MHz - LFM, Low Frequency Mode
6.0 x 133 MHz = 798 MHz - SLFM, Super Low Frequency Mode
When I unticked SLFM in TS, the clock only dropped to 8X instead. It seems like when I am in a game/movie the CPU thinks that it's not really under load and it just drops its frequency for a minute. It doesn't seem to be affected by temperature, doesnt matter how much I stress the cpu. It just occassionally happens.

I don't believe this has to do anything w the battery, as I am using my T601 from AC when this happens. I also have a genuine panasonic battery, and all PM settings are on max perfomance on both BIOS and W7. Any thoughts? Thanks.

No problem.

When you said that your clock multiplier could be overwritten back to its original (12.5x?), does that mean your clock multiplier doesn't drop back to the lowest as it should? As in whenever you would do something intensive with the GMA X3100 and the T9300 in use, the T9300 no longer drops its clock multiplier to its lowest possible when Throttlestop is left running in the background?

If the battery and the AC adapter has nothing to do with the random frequency dips, I am guessing something is not quite right on the power management side. Is the ThinkPad Power Management driver installed in your T61? Also, could you check if Windows' power management plan has the system cooling policy option set to 'Active' instead of 'Passive'?

Yes, that's correct, when I turn on Throttlestop with a set multiplier 12.5X, this whole frequency drop thing is fixed. However I would like to understand why my CPU does this, as this seems far from being normal. Yeah, the PM stuff could be the reason, but I have the PM driver installed and I have system cooling policy at active.

So it sounds like Screamers' advice has helped resolved the multiplier issue for the time being but your questions still remain regarding why this is happening in the first place. My best guess is SLFM, your power settings configured in the BIOS may be a good place to start. My recommendation is to try disabling speedstep completely from the BIOS and then run ThrottleStop using Task Scheduler. This way you have total control over your multiplier from when you start up. Since you have middleton BIOS it shouldn't matter but also check Dual IDA mode in ThrottleStop to get the CPU to a 13% overclock to 2.7Ghz.

Thanks storm-chaser. I attached my bios config as I had till now

http://hixon.hu/frankenpad/t9300bios.jpg

as you see I tried to set everything in order to avoid this clock multiplier drop. When I disabled speedstep, something interesting happened. I had my CPU locked with 6X multiplier (1200Mhz) and it stayed like that regardless of the load. Is this normal btw? I was expecting the CPU to run at 2500Mhz with disabling the speedstep. Yea, currently the best solution would be to leave everything as it was, and use throttlestop whenever I do something more intensive with the X3100 and the cpu, speedsteping is still important as I sometimes use my frankie from battery and would like to have longer battery time/life. But hoping to find a better solution.

Good to hear that Throttlestop actually worked for that kind of a weird situation. Having the Power Management driver installed, and yet this still somehow happens..

As for the clock multiplier dropping to 6x when SpeedStep is disabled, yes, that is normal. I don't know the exact reason for that result, though. My guess is that it had something to do with insane people that shoehorned Mobile Pentium 4-M processors into a desktop Pentium 4 motherboard, to overclock it and to potentially make a cool-running Pentium 4 setup. After all, the Mobile Pentium 4-M processors ran on a lower operating voltage, making them run cooler compared to a desktop Pentium 4.

Could you try resetting the BIOS' settings to its factory defaults, and then check if the clock multiplier drops again? If that does not work, try disabling PCI Bus Power Management and PCI Express Power Management, but leave CPU Power Management enabled.

With bios factory reseted, I keep getting the frequncy drop :( PCI bus & express PM disable did not help either. However, I think with the default settings I keep getting this multiplier drop more than with the settings I had before, but that might be just an optical illusion :D Thanks all, whats next?

Well, crap. Sorry about the even more frequent frequency drop, I thought I had a feeling that it could be something related to the PCI bus and thought of those 2 options.

The last thing I had on my mind is the embedded controller's firmware version, do you have version 1.08?

Yes, embedded firmware is 1.08. I will get another t9300 in a couple of weeks time, and already got another two 4:3 T61 motherboards, will swap the ssd and see if there is a difference. Till then I will use TS whenever I need to. :)

Hello, I had the same problem a few years ago. I managed to solve it by using the CCleaner program to clean registry and remove the CMOS battery. If that does not help, try uninstalling the PowerManager with the drivers and using a different version of PWRM.

I'd skip CCleaner, most of us who work with computers know that software creates more problems than it solves (even beats a certain deadbeat OS).

That said, the CMOS thing is interesting. Removing a CMOS battery for longer than 5 or so minutes is akin to a hard reset (pressing down the power button) on the BIOS running in the planar. It usually clears custom settings and returns it to factory reset.

This option, if convenient to the OP, might be worth exploring.
