I actually wrote an 8 core version of RealTemp a few years ago. The guy on XtremeSystems that I wrote it for decided that he didn't like it because it was too wide. No kidding. :)

He thought for 8 cores maybe a redesign of RealTemp so it listed the temps in a table so it wasn't so big might be a better idea. Kind of like how Core Temp or CPUID HWMonitor do it. I don't have access to an 8 core CPU but in theory, either of those 2 programs should be able to handle the 5960X. If anyone has an 8 core CPU and wants to help me get RealTemp working, let me know and I will see if I can find my old code. A couple of minor updates might be enough.

I've been using the Skull=1 Skull=2 options with two instances of realtemp running for years now on my dual quad xeon setup. The only issue I've found is you can't launch the two instances of realtemp at once, most of the time one of them will be messed up, I don't recall the specifics. I use a batch file to launch one, wait, then launch the other. I'm also planning to pick up an 5960X soon. I'm just waiting a bit (for a change) to let everyone iron out all the kinks first. If there's anything I can do to help let me know.

Hi Uncle, first I wanna say thanks for this great program and pardon my english since it's not my first language.
I have recently downloaded your last version de RealTemp_TI one, and since I have a new i7 5820k CPU, it doesn't display my full six cores, is there anywhere a RealTemp_TI GT version displaying six cores? thanxs in advance.

RealTemp GT 3.70 works correctly on the 6 cores CPUs and it can be downloaded from TechPowerUp.

The T|I Edition only supports the 4 core CPUs.

RealTempGT.exe still only shows 6 of 8 cores. An update would be greatly appreciated.

Guys my CPU idle temps are about 25C, but the BIOS reads in 40s? Which one is correct? hwinfo also gives 25C as CPU temp

One is your package temperature, the other is the core temperature.

They will usually be 10-15~degrees different.

I would use AMD Overdrive to monitor since it tells you when your nearing the max temp limit

Sorry, I changed my system specs. I have a 6700k now.

Also what does a sensor test do and tell me? (specifically the movement part)

When you are sitting in the bios, the CPU is typically not using any of the low power C States so the temperatures tend to be higher in the bios compared to when idle in Windows. As mentioned, the bios might also be reading data from a totally different CPU temperature sensor.

The CPU Cool Down Test was invented to help uncover the 45nm Core 2 Duo CPUs that had sticking temperature sensors. As the load on a CPU decreases, the temperature should decrease. This test worked great for that problem and I am sure it helped encourage Intel to start using more expensive temperature sensors that no longer get stuck in the normal temperature range. When a load is applied to a CPU, the core temperatures should instantly increase. That is what the movement part of the test shows. On 45nm Core 2 Duo CPUs, a movement reading of zero showed that the sensor likely had a sticking problem and was not moving at all when at low temperatures. Many of these sensors were getting stuck at anything less than 45°C. Your sensors look fine.

RealTemp has not been updated in 4+ years. It reports the temperatures correctly on a 6700K but the MHz and Load data needs some work. I plan to look into this someday when I can afford a new system with a 6600K. No money in the sock drawer at the moment. A freeware programmer is kind of like a starving artist. We produce good work but neither of us are getting rich. :)

I posted on my motherboard manufacturers website and they had the same thing to say. The temp goes up in the BIOS screen.

I built a new skylake system recently, now when I open realtemp it shows the core temps around 20 degrees all day (idle), while my room temp is around 20 as well.
realtemp.JPG


Now this seems a little hard to believe.
I did a sensor test and it says this:
sensor test.JPG


To get the right temperatures at idle do I have to add 12 degrees?
Then core 0 would run at 32 degrees.

I must say in the UEFI the cpu temp reads around 23.

Intel has never used temperature sensors that are 100% accurate. These sensors are calibrated to trigger thermal throttling at approximately 100°C and to trigger thermal shutdown at about 125°C to 130°C. Accurate idle temps has never been part of the design. At the calibration point, these sensors are only accurate to +/- 5°C and when the CPU is idle, they are probably less accurate than that. They tend to read too low at idle so your reported temps are normal.

The Sensor test simply shows that all of your sensors are working. When that test was originally written, many of the 45nm Core 2 sensors were getting completely stuck at temperatures below 40°C. This test proved that point but this test has no significance when running it on a Core i CPU.

As long as your CPU is stable and it is not thermal throttling, core temperatures are not that important. Temperature data is an approximation. If your cores are at 60°C or 70°C or 80°C, it really doesn't make any difference. Your CPU will perform the same and it is designed to last a long, long time at any of those temperatures.

as i tell people, go by distance to TJmax - or distance to throttle. idle readings mean nothing, when various chips can throttle at 60C or 110C - how long til that happens, is what matters.

Is the latest beta RealTemp still in a test phase?
Will it be out soon?


Thanks!

I have not looked at RealTemp in years. I prefer to work on ThrottleStop. Same sort of monitoring program and it uses a lot of the exact same code. It shows CPU and GPU temps in the system tray and gives a user way more control over their CPU compared to RealTemp. I am running out of new stuff to add to ThrottleStop so maybe I will get back to working on RealTemp someday soon. Technology changes quickly so it is difficult to leave a program like this sitting for years and then just do a quick update. Dormant projects take a lot of time to get them working properly again.

So, am I the only one who noticed Real Temp doesnt shows the real tmps on Kaby Lake CPUs ???
p.s. It shows 8-12 degrees lower.

Intel has not changed anything temperature related in the last 7 generations of CPUs so RealTemp should be able to read the correct temperature on Kaby Lake CPUs. Either download a fresh copy of RealTemp or delete the RealTemp.INI file and restart RealTemp so it can read the correct value for TJ Max from your new CPU.

If you ever have a problem, post a pic so I can have a look.

Yes, thank you. You're right.I use this app for a long time now so i guess someting went wrong when switched the gens.

Dear Developers,

The program is really useful, but i have an issue with it.
The ALARM EXE that I point out is called only once in event of alarm.
I have made a script, sending me email when the temperature goes above a specified amount.
The problem is that ALARM EXE /which triggers my own script/ runs only at the first occurrence of higher temperature, and not every time the event occurs.

Could you, please make the program ALART to be triggered each time a criteria has been met?

Thank you in advance!

PS Sorry if I didn't write my request in the right topic.

intel says on their spec sheet that tjmax for X5670 is 81.3C ...Realtemp says 96 C. I think realtemp is incorrect in this instance.

If you look closer at the spec that you posted, 81.3°C is listed as the maximum TCase temperature. This spec is not the same as TJ Max.

TCase is measured by hacking up the top of the IHS on top of your CPU with a Dremel and then embedding a temperature sensor at the geometric center of your CPU. This spec is not for individual users because Intel does not expect individuals to hack up their new CPUs. This spec only applies to large system builders that are trying to determine how big a cooler and how much air flow they are going to need. If the center of the CPU never reaches the maximum TCase temperature when testing then in theory, the hottest spot on the individual cores should never reach TJ Max. It is not unusual for there to be a 20°C gradient between the temperature measured at the center of the CPU vs the peak core temperature. The size of the gradient varies depending on your cooler and the type of stress testing software you are using. The TCase spec is a guide line so the CPU will be unlikely to need to thermal throttle. Intel wants the CPU cores to always run at their maximum rated speed when necessary.

When RealTempGT first starts up, it reads the Intel specified TJ Max value directly from the CPU. If you have RealTemp installed on a USB drive or if you previously had a different CPU, delete the RealTempGT.INI config file and then start up RealTempGT.exe so it can read the correct TJ Max value for your CPU.

A 201 MHz BCLK looks great for a 6 core CPU that is over 7 years old now. :toast:

Thanks for clarifying the temps thing, i had to read it twice but it all makes a lot of sense now.

Here is a good thermal pic of an old Core 2 Duo. It shows you the hot spots on the die compared to the center of the CPU where TCase is measured.

Nice to see that RealTemp and CPU-Z agree on your BCLK, 201.35 MHz. You can also trust the RealTemp multiplier. Your previous picture looks like you might have C1E enabled.

Thanks Rosie.

i never have any problems so i leave it as it is,

This is the best i ever did with it , the hardest work it does nowadays is GTAV
