today i updated my BIOS to the newest Version and i have the same issue. Hope on getting a feexed Version soon.
I'm getting sad... Thought of beeing on the bright side with an Intel-Board....
A BIOS with a fix for this issue is in the works. The same issue that is causing the BIOS to see incorrect temperature readings also affects the Intel(R) Desktop Utilities application in the Windows environment. The BIOS fix will address this as well. We don't have a firm ETA for the BIOS release as yet, but it is measured in weeks not months...
I have the same problem.
Also, which is probably related, my CPU fan started running at full speed as soon as I upgraded. (My other fans are not affected as they are controlled by a speed controller connected directly to the PSU.) I managed to bring the CPU fan speed down to where it was before the ugprade by switching the CPU fan speed control from AUTOMATIC to MANUAL.
We use diodes or thermistors to implement the on-board sensors (VR and Memory). In some designs, an offset is necessary to "zero" the sensor and make readings accurate and the DH87MC board is one of these. We have an issue here where the offsets were accidently dropped from the BIOS. This results, in this board's case, in the readings being artificially high.
From an impact standpoint, the incorrect readings can be ignored. Within Intel(R) Desktop Utilities, if readings get high enough to cause alerts, the alert can be disabled or set to a higher threshold.
We are sorry for the inconvenience. Due to other fixes being included in the next MC BIOS, the BIOS must undergo full validation and thus will be a few weeks before release...
what is wrong now ? Have installed Bios 0153 and Set Cooling in bios to Balanced (4) and my CPU Cooler when run PC 1980rpm running and CPU One Core 34 and other cores bolow 34. Only when Set to 2 or lower, cooler run with 1050 RPM. Another Bios bug ? Memory and VR ok now.
I have since confirmed that there is indeed a bug in the fan speed control configuration code. The Intel(R) Quiet System Technology (QST) algorithms in the eSIO are being improperly programmed if either the Piece-Wise Linear or Simple Linear algorithms are selected. I am currently working on a fix. Updated releases of the BIOS for each board, as well as an updated release of Intel(R) Desktop Utilities (since it shares the same code), will be necessary to address the issue completely.
It will take a few weeks for the fix and the subsequent BIOS and IDU updates to be fully verified and released. In the meantime, if you are using the advanced cooling configuration parameters, stick with the Proportional-Integral-Derivative (PID) or Temperature Range Management algorithms. For those using only the Visual BIOS Cooling Assistant slider, this means using only settings 0, 1 or 2 for now...
Sorry for the inconvenience,
I upgraded the bios to latest version 157 and this is what put me in trouble.
Now I am unable to go into F2 setup, system gets freeze and no way, other than reset.
However, as a workaround I did bios recovery and installed the 152 version. it allowed me to get into F2, but started getting the temperature issues.
In setup, memory temperature is displaying current value as 85.50C, where as recommend threshold is 68C.
Please suggest, do I need to get my motherboard replaced or just increase the threshold value for now & hope it's not to do any further damage to rest of the connected components.
Even tried recovering the 154, 155, 156 version of bios, but nothing works...
Regarding the (now) inaccurate temperature readings, there are two issues. First, you want to get to the latest BIOS if at all possible. If you are having problems getting into BIOS Setup, make sure you start hitting the key right at power on or reset; don't wait for the prompt to start doing so. Second, doing the multiple backward-and-forward BIOS updates has likely resulted in some corruption in the FSC variable. To correct this, try doing the following:
- Within BIOS setup, press to restore the default settings for all parameters. Save and exit from BIOS setup. Enter BIOS setup again and check whether the temperatures are now displaying properly. If they are, you are good to go. If not, however, try step 2.
- Within BIOS setup, navigate to the Fan Speed Control configuration page and make a change to at least one parameter. Any parameter will do. For example, increase or decrease a temperature or fan duty cycle by one. Save and exit from BIOS setup. Enter BIOS setup again and check whether the temperatures are now displaying properly.
Let me know what happens...
Wondering if others are still having the issue with incorrect or unusual memory and vr temperature readings on their HD87MC motherboard. I bought mine last week along with a Core i5-4670. I updated the bios to version 0154 dated January 23, 2014. My memory temperature is 64 degrees Celsius and vr temperature is 59 degrees Celsius. The processor temperature is 27 degrees Celsius. I get the same readings both in bios and in Intel Desktop Utilities. The memory modules themselves are cool to the touch. Thanks.
I've been trying to download the utility program (3.2.6.068) on my DH87MC board and it will not open. I get the outline of the monitor box with the logo, but the wheel just continues to spin. Has this been altered so no one else gets into the false temp reading issue? Jim.
In order to get the fix for this issue, please download and use the latest version of Intel Desktop Utilities, 3.2.8.089.
P.S. I am tracking an issue wherein folks that have done Windows upgrades (Win8 to Win8.1 especially) end up in a state where all they see is the spinner. I have a workaround that worked for one customer that you can try if you are stuck at the spinner. Open the folder where you unzipped the IDU installation package, navigate down into the SMBus subfolder and then double-click on the Setup.exe file found there. This will run the SMBus driver installer manually. Click through and complete its install. Do a reboot (this should happen automatically when you exit the installer; do it manually if it doesn't). After the reboot, IDU should run properly. If it doesn't, send me a private message. Attach file "C:\Program Files (x86)\Intel\FSC\FSCAppServ.log" to this message...
OK, did that, still the same. I've looked for the log file, but it doesn't come up. Is this one of those files that I have to go somewhere and say to show hidden files? Oh, and I don't think I specified before, I'm running Win 7 Pro 64 with an I5 4670K processor, just in case that makes a difference. Fresh install. Thanks! Jim.
And now I've done it. Thought I found how to make the hidden files visible, and now the programs 86 folder is gone. I can open programs that the properties say they are in the programs 86 folder, but the folder is now hidden? I should have left it alone. Any help you can offer??? Jim.
There are no hidden files to worry about, but you need to be careful to handle the spaces in the folder names. The easiest way to do this is use explorer and start from the root of your hard drive (i.e. C:\). Browse into "Program Files (x86)" then "Intel" then "FSC". The file you want to grab is named "FSCAppServ.log". Note that there is also a "Program Files" folder in the root as well; this is not what you want...
