HOW TO: Monitoring CPU and GPU Temperatures In-Game/In-Benchmark with On-Screen Display

[steviejones133]

Thanks RV for the detailed explanation of Compal EC vs Dell EC. Assuming Dell EC is more stable to use, how do you disable the below to avoid DPC Latency? (please forgive my "noobness" regarding HWiNFO!)

Compal EC shows no latency when Fan rpm readings are shown in sensors. Dell ec shows latency when those are shown... disabling and hiding them in sensor config fixes that.

Also, how do you make the following changes below?

Second thing to note is if you are using a laptop "GPU I2C Support" and "GPU I2C via NVAPI" should be unchecked as they are unused for a laptop and only pertain to Desktop GPU's

Somehow, my config page has some differences, namely only one line for cpu when compared to your screenshots for Dell EC from your post on page 2



I am using the following settings (because of stability purposes) and DPC Latency is horrendous....so how do I rectify the latency problem?

For stability, the following configuration is recommended:

I don't use the persistent driver option and prefer not to. I use the portable zip version. I can use the settings in my original screen shot (post #1) or the recommended stable settings in the second screen shot (post #2) and do not have any noticeable performance or stability problems either way. This may be because I use the portable version without the persistent driver. Nothing is installed within Windows, but I find HWiNFO64 does anything and everything I want it to.

I too am using the portable version Mr. Fox, I also have HWiNFO64 configured exactly like your shot in post #2 but when I run LatencyMon, it goes nuts.....RV mentioned about "disabling fan sensors" rectifying Latency using Dell EC - how? .... if you look at my screenshot above (where I circled) its completely different to RV's Dell EC shot on his post #19 - I only seem to have one line for cpu , for some reason, where RV has two cpu lines and a system/gpu line

[Mr. Fox]

Brother Steve, try going back to the original HWiNFO64 configuration instead of the alternate configuration shown in post #2. I had been running the configuration noted in the first post (using Compal EC) all along, and doing so without any stability issues or DPC latency. I switched over to the Dell EC configuration as noted in post #2 and found no meaningful difference on my system.

After using the configuration noted in post #2 for a couple of days, I went back to using the Compal EC simply because I like using its monitoring features better and you can use a wider range of fan speeds with custom fan controls. After switching back to the Compal EC everything still worked flawlessly on my system. I have no DPC latency issues on the Compal EC using custom fan controls using the NVIDIA sensors or using the native M18x fan controls.

I have edited post #2 to read "Optional: If you experience stability problems, try this alternative configuration to use the Dell EC:" as it does not appear to be a problematic setup on every system. Rather than taking a one size fits all approach, users should feel free to test both ways and decide which of the two configurations works best on their system.

I am using the GPU12C options with the GTX 580M and find it to work really well for me even though those options are stated to be intended for desktop GPUs. (They may not work as intended with AMD mobile GPUs, so AMD users need to test both configurations to find out.)

Thanks Mr. Fox - I still am left wondering why my HWiNFO config page differs from that OF Brother RV's, when using Dell EC. I just rolled back my system to before I started tinkering and have dowloaded HWiNFO again from your CNET link. Having run it under Compal EC settings, under Compal EC in the config window I see two lines - one cpu and one gpu...

[Mr. Fox]

Maybe having an unlock BIOS has an effect on what is displayed in the sensors window. Not sure, bro. However, if everything works well I would not consider anything to be particularly wrong. If not a difference from the unlocked BIOS, it might just be a random bug with HWiNFO64.

I have attached my HWiNFO64.INI file. This works fine for me using the portable 3.92-1515 version. You might try renaming yours HWiNFO64.INI.old and copy the attached into the same folder, then re-launch HWiNFO64 and see if anything changes. If nothing changes, it might not be worth spending more energy trying to figure out if there are no problems otherwise.

Thanks for the advice and for the .ini Bro, much appreciated. I probably wont dwell on it too much longer anyway as its no biggie - my inquisitive nature was kicking in and making me question myself as to why my entries were different to RV's, thinking I had maybe missed something.

I know Brother RV said about disabling fan monitoring and I was also curious as to how to do that - only because if I chose to use Dell EC as opposed to Compal EC, I want to eliminate DPC Latency issues which, for me, with settings as per post #2, are crazy high....

Maybe RV can advise/clarify on how to disable whatever needs disabling to eliminate latency using Dell EC settings - then I have the option of Dell or Compal EC....

specifically I have seen a few fan rpm readings those are the offending sensors. Start in the HWiNFO sensors window not the config. Identify all the fan speed readings showing rpms even if its only 0rpm. First you guys now how GPUZ has a fan reading for our GPUs yet its not accurate and often says 0rpm? Well HWiNFO with default settings shows one per gpu under the gpu Sensor section in the sensor window. So assuming you have Crossfire or SLI on our M18x's take note of those two names of the fan rpm sensor for the gpus since it may not be a clear name by default. Look now at the DELL EC section in the sensor window. There should be a temp, and two fan rpm readings one claims cpu and the other claims system/gpu and should be showing the rpm readings of your fans. those are the other targeted ones. So that's 4 sensor readings to note name and heading they were listed under. Open the config in the sensors window and hunt down each of those under the right section... if you didn't note the names it would be harder to find because they are not labeled fan speed reading by default at all. Go to the right hand side of the options and disable the sensor reading which will automatically hide and gray out the show sensor checkbox too. Now its not being read and its not just hidden from the sensor window. I had just a version or so back on those pics but it still applies If they are completely not shown and the DPC latency is still showing check for any other rpm readings you may see. If still perhaps we have different setups and something else is causing the issue. Disable wireless network card and possibly any other extra cards just to refine what is running. That's how I knew it was only the settings I was using that showed the dpc latency or not. So just in case that is what was giving dpc issues too adding to what you see in the DPC app.
As per the latest version of HWiNFO I used to only find for the DELL EC autofan profile option the only good sensor to read from was DELL EC - CPU temp reading... now I use one that has appeared recently in the latest HWiNFO version. Its called "Intel CPU#0" and its temp reading is very accurate ranging from min to max temps where I didn't see Dell EC temp reading showing accurate readings comparing it to the Intel Digital Thermal Sensor reading... whereas this IntelCPU#0 reading has been spot on and I've confirmed it to fully work with the custom profile accurately changing fan speed as per your custom temp profile

I spoke to Mumak directly and he is glad to answer as many questions as anyone may have on any matter at all regarding HWiNFO. He is very patient and helpful. He is the creator of HWiNFO and can answer anything HWiNFO related better than anyone else. He said he doesn't mind if anyone asks him directly on any of the matter that's a very kind gesture I do believe He can be contacted as I linked above here :

the noted DPC Latency is even noted right on his own forum issue #3 thats noted
Known Issues

he prefers fan related topics be asked at the above and not as new topics in his own forum thank you for respecting his request

[steviejones133]

Thanks RV. I will do as you advised and see how it goes. I will also read up a bit more on HWiNFO over at the links provided.

Cheers.

Perhaps the links were not allowed as per NBR forum rules Stevie so the only link that is okay is the one to HWiNFO's known issues list. Your welcome though and I believe you know where to seek more info. I spoke more to Mumak and as per fan control via Compal and DELL method... there is no clear cut stable for all answer For GT580m and a config like Mr.Fox's computer above may very well be completely stable using the Compal EC There were many reports but there are so many variations of setups nothing is clear cut. There were more reports from AMD users using the Compal EC of issues than the Nvidia users. So Mr.Fox your advice above is sound all of you should test the versions yourself and determine what best suits you. AMD users may want to consider the high reports of issues and use the Dell EC over the Compal EC and Nvidia users the opposite may end up being true although there hadn't been issues on the Dell EC as of yet. So again MR.Fox put it good above please test and use whichever version works best for you. Mumak is glad to assist anyone as I said. Cheers. Stevie I hope I was of assistance. here is updated pic on the Dell EC sensor for latest HWiNFO version since you said they weren't showing I see the names are missing in new version... but those two are still the ones to disable.. the other one is just a temp sensor and causes no latency.

Spoiler :

Also to be honest if a user here is just monitoring and not using fan control in HWiNFO one should uncheck all three of these the "SW SMI" in HWiNFO options as well as "LPC & EC Support" and "EC-ACPI Synchronization" so there is no need to worry of any latency or fan control when one didn't plan to use it anyway.
