    I'm a little biased and I like RealTemp better but Core Temp would be my number 2 choice. It is one of the very few programs that is reading temperature data from all 4 cores when hyper threading is enabled. Many monitoring programs, even popular commercial ones, hint, hint, hint, do not.

    Chris Z.: I was wondering how long it would take someone to ask, "What's going on here with these multipliers in RealTemp 3.40?"

    The older one shows the correct value.
    Who says that is the correct value? The older version of RealTemp might show what every other monitoring program will show at idle but how do we know that is actually true.

    What I discovered at idle is that how you have Windows set up will affect what your multiplier is really doing. Almost all software has decided to over look the truth and instead provide you with a nice steady multiplier even though internally, the multiplier your CPU is using might be in a state of chaos.

    I don't have a QX processor to test with so hopefully you can do some testing to try and prove this.

    There is another program in the RealTemp download called i7 Turbo. Try running that and RealTemp 3.40 and CPU-Z. When testing, turn off Everest and all other monitoring software because I'm not sure how other programs use the system timers that RealTemp 3.40 and i7 Turbo depend on.

    In Windows Vista and Windows 7 there is a setting in the Control Panel -> Power Options called the Minimum processor state that has to be set to a low number to get the multiplier to go down to 6.0 at idle. For testing you can set this to 5%. If this setting does not exist then you might need to go into your bios and enable SpeedStep / EIST.

    If you are using Windows XP, then one thing that controls this is also in the Power Options. Click on the Power Schemes tab and try changing the scheme from Home/Office Desk to Portable/Laptop.

    The C1E setting also can play a part in what multiplier you end up with at idle. Enable C1E to lower your idle multiplier and disable C1E if you want a high multiplier at idle. This setting might not do anything depending on what you have set in your Power Options.

    Once Windows has a chance to settle down, are the multipliers reported by i7 Turbo closer to 6.0? Post a screen shot of those 3 programs so I can have a look.

    Now run a program like Prime 95 on all 4 cores and post another screen shot of those 3 monitoring programs.

    What I found during development is that the internal timers that accurately record what multiplier your CPU is using, sometimes tell a completely different story than what most software will tell you at idle. I fully trust what the internal timers are telling me. It's possible that I've screwed something up on your QX CPU but for most Core 2 Desktop and Mobile CPUs and Core i7 / i5 / Nehalem CPUs; what RealTemp and i7 Turbo are saying is in fact what's really going on inside your CPU.

    If your hardware / bios settings do not agree with your Windows settings, you can end up with a multiplier that constantly hunts up and down at idle between 6.0 and the maximum multiplier. Once you play with your Windows settings, you should have some control over your actual multiplier at idle.





    I have seen one early QX6700 Engineering Sample CPU that had the internal timers disabled but I don't think that is the problem in this situation.
