My (old)e8400 had the same VID from a X38 Asus Maximus Formula to my EVGA 780i on Core temp...

1.2375V for VID...which corresponds with what my bios says is the default Vcore for my CPU.

My personal opinion is that the VID that CoreTemp reports is a meaningless number because it can change depending on what motherboard you are using. The VID that RealTemp is reporting might be just as meaningless. I don't know if either program is telling you anything that is hard coded into the chip itself. Intel does not seem to publicly document this information probably because they don't want people hunting through a bunch of chips and trying to find a good one based on VID and returning the rest. I'll tweak the formula used based on the data posted but I won't be too upset if things don't line up exactly with CoreTemp. I've already learned that "just like CoreTemp" is not always a good thing. :D

Captn: Use the test as outlined in Post#1. You might need to go into the RealTemp.ini file and add this:

Idle0=1

but without doing the test, it's impossible for me to say. Show us some full Prime small FFT load temps as well.

msgclb: I apologize for trying to rub your nose that your dual core chip is missing a couple of cores! That's why these are beta versions. So users can report the issues and then I can fix them.

Edit: Here's my second try at VID that looks just like CoreTemp so everyone will be happy.

Edit#2: Just checked all the above posts and the new formula seems to work. Now we need someone to install their CPU in two different motherboards and see if the VID stays the same or changes between different boards.

:( Uncle - the link does not work for me.......:confused: Always get a folder with only 34KB and the main symbol in it, but no data...... - what happened?

The link in the first post for the older version works fine.......

Help - I want it ! :D

Both links look identical!
The size of the file is 34kb.
I just tried it again and it's v2.47 and the tooltip now works for dual core.

Core temp shows a VID of 1.1250 vs Real Temp saying 1.2375. Default on first boot was 1.2v bios, with 1.18 idle CPUz. Real Temp is closer to the bios with this Q9450.

As I said before, the documentation from Intel is lacking and VID is stored in multiple locations and you also have your current VID as well as the max VID. RealTemp is presently reading what it thinks is the current VID. I'm not sure what MSR that CoreTemp is reading or what formula it uses to determiine voltage. The more feedback and numbers the better. I'll be updating the main link within a couple of days. RMClock also displays VID so you might want to compare to that as well.

Edit: I think I guessed right when I was playing the game of trying to interpret Intel's missing documentation. As for the competition, well I'll let you come to your own conclusions. The VID displayed in RealTemp also changes as my wife's laptop goes through its SpeedStep / C1E transitions so I think I'll be keeping this new code just as it is, even if it doesn't always match CoreTemp. :D

VID represents the voltage that a processor is requesting from a motherboard. Not all desktop motherboards listen though and they can come to their own conclusion and give the processor whatever voltage they like, especially if you've been in the bios and have set core voltage manually. CPU-Z reports actual core voltage.

Looks like the Dell laptop motherboard is listening to what the T7200 is telling it to do.

Just a couple of more comparisons. RMClock is on the far right and it is using the same VID values that CoreTemp uses.
EDIT:
I just noticed that CPU-Z is reporting the VID for this mobile processor. On desktop processors it shows Core Voltage but here it shows VID. I trust CPU-Z more than CoreTemp or RMClock so hopefully RealTemp is doing this right now. I'm not sure what those other two programs are displaying for VID.

Unclewebb I ran Orthos for 57min and heres what I got for temps, my voltage for cpu is set at 1.29375 in my bios. Does anyone know of a great free screen capture program other then MS Paint...lol.

Captn: The sensors in the B2 are pretty good and yours seem to be lining up well under full load. If you want your readings to be a little more accurate at idle then try what I recommended before.

Idle0=1

This will make your idle temps closer together but if your biggest concern is load temps then just leave it as is since your load temps are balanced. Send me a log file showing 1 minute of idle, 3 minutes of Orthos and then 1 minute of idle. It's a lot easier to judge when I can see the numbers.

The latest beta, 2.47, will fix your VID reading as well as the two blank cores that pop up in the tool tray area.

My fav free picture program is Irfanview. It's not a screen capture program but you can just press the Print Screen button on your keyboard then go into Irfanview and Paste it into that program. For simple cropping and saving in different formats it works good.

I am using real temp and the Core temp is 41c 41c 39c 40c

minimum temp is 40c 40c 39c 40c

maximum temp is 43c 43c 41c 47c

Is this OK

I think my cpu is running hot but I do not now how to upload the real temp from my desktop to show you folks?

can someone help please

Nice TY for that program, I clicked your latest link for Real Temp and im still getting 2.46. Did i do something wrong?

How are you suppost to tell if you need to lower the idle temp calibration?

now Realtemp says VID = 1,225 and that is the same as on the E8400 Package label 1,225 maxV. Coretemp reports 1,1125V.

:D RT says VID 1.1250, CT 1.0000 and BIOS stock auto setting is 1.0800.

I jumped back to 2.41, I love to see the temps constantly in the task bar.

Idle calibration works fine - my previous QX9600 with working temp sensors ran with chilled water (12°C) @4GHz @1.208v 7-8°C above water temp.

But I ran it at 400MHz FSB, my E8500 is doing 500FSB @4GHz @1.232v. But the QX has 130 watts, the wolfdale only 65.

So I calibrated my Idle temp for the E8500 8°C above water temp - should be close to the truth.

BTW, I noticed RT shows only straight numbers, i.e. 18°, 20°, 22° and so on,
but never 17° or 19° and so on. Why?

Coretemp VID for my Q6600 is the same on my 680i as it is on my P5K-E.

Only have P5k-E screenshot atm.

I just found a trick in CPU-Z. If you go into the cpuz.ini file and set this value to OFF:

Sensor=OFF

It tells CPU-Z to not read your sensors. Instead of displaying your measured Core Voltage, it will display the VID instead. So far, RealTemp is matching what CPU-Z displays for VID. If yours is different then post a screen shot.

I thought about making that an option. It's very simple so I'll try to include that in the next update. When using a positive calibration factor it is possible that RealTemp will skip a temperature number and when using a negative calibration factor it is possible that RealTemp will display the same absolute temperature for two DTS values that differ by one. This is what you get when writing a calibration formula with data coming from digital thermal sensors that are only outputting whole numbers. Tell me the TjMax you are using and the calibration factor and I'll PM you a chart of the temp numbers that you will get.

Milamber: Read post#1 for more info.

That seems to be an issue with Firefox. If you go into Tools -> Options -> Advanced and Clear the Cache you should get the most updated version when you click on the RealTempBeta link.

:D Nice - I use the default setting TjMax 95°C for my E8500, calibration factor is -2. THX !!!;)

Clear your cache in Firefox if you have to and try again.

I added an extra item for the INI file today:

TaskBar=1

For people like camouflage that like their temps in the bottom task bar just add the above line. I felt bad that he had to use an older version. :(
