    Issues with DH77EB (BIOS 0071) and Core i5 3550

    bluebomber

      Hi everyone,

       

      I recently assembled my own desktop PC with the following components:

       

      Intel Core i5 3550 processor

      Intel DH77EB uATX motherboard

      Intel 330 120GB SSD

      Corsair TX650 V2 PSU

      Corsair Vengeance 8GB (2x4GB) PC3-12800 DDR3-1600 CL8 RAM

      Sapphire Radeon HD 7850 graphics card

      ASUS PCE-N15 wireless network adapter

      Cooler Master 120mm 2000rpm exhaust fan

      Silverstone Temjin TJ08B-E uATX case

       

      Everything is functioning now for the most part, but I have the following questions:

       

      1. When I started the PC for the first time, I flipped on the PSU switch and powered on the PC. I could see that the motherboard light was on, but after starting the fans for a split-second, the machine shut off. After a few attempts, I realized that I had missed the 2x2-pin 12V connector from the PSU to the motherboard. After plugging it in, my PC started up. The manual states that failure to plug in the 12V connector "may cause damage to the board". Should I be worried? Everything seems to work, but I'm not sure if there's any underlying damage to the motherboard and/or other components. Is there a tool to check the health of all components?

       

      2. I notice that when I perform a cold start on the PC, the CPU fan does not start immediately. For the first 5 seconds or so, the fan will perform two "false starts", followed by full acceleration to ~3000RPM, and then a slow-down to the normal ~1000RPM. Is this behaviour normal? I ask because I've never experienced this before with a CPU fan and I worry that the delay in fan activation may cause damage to the CPU due to excessive heat.

       

      3. Although I purchased and installed DDR3-1600 RAM, Intel Desktop Utilities (IDU) reported a speed of 1333MHz. I tried switching the RAM timings profile in the BIOS to XMP (and it showed timings 8-8-8-24 with speed of 1600MHz in the BIOS). When I return to IDU, however, the RAM is still reported at 1333MHz. Am I doing something wrong?

       

      4. I updated the BIOS (from 0053 to 0071) thinking the new release might fix some of the issues I was having. After updating to BIOS 0071, I noticed that my Cooler Master 120mm fan outlet (exhaust) speed is constantly at 100% (2000RPM). Prior to the update, it ran at ~1000RPM. I attempted to adjust the outlet fan speed in the BIOS, but doing so had no effect whatsoever. Is this a known issue? Is there a way I can adjust the outlet fan speed?

       

      5. Additionally, after updating the BIOS, IDU no longer detects my system. When I start IDU, the spinning image (loading image) continues to spin and doesn't stop. Is this a known issue? Is there a way to have IDU detect my system again?

       

      Thanks in advance and any help is greatly appreciated.

          Hi

           

          1) I doubt you have caused any issues, the motherboard shut itself down to prevent any damage.  There is nothing that will test all the components outside of the factory.  The fact everything is working though should be confirmation that all is okay.

           

          2) All sorts of funny things have been going on with the fans on these BIOS's, doesn't sound like anything to worry about.  Typically fans are run quickly at high speed when first switching on to get them going.

           

          3) The default is for memory to usually report itself as 1333 as a fail safe.  Using the XMP profile is what you will need to do in order to run at 1600.  IDU incorrectly continues to report the default speed, and not the actual speed.  If you download CPU-Z it will tell you the actual running DRAM frequency, you need to multiply by 2 to get the DRAM speed.

           

          4) See answer 2.  I have the DZ77BH-55K and updating the BIOS caused all fans to run full speed.  I fixed this by going into the classic BIOS (not visual) and resetting to defaults from there.  That has fixed it for me and at least one other person reported that fixed it for them also.

           

          5) There have been several reports of the same thing.  You can use HWMonitor while Intel sorts out a fix.

           

          Hope that helps.

           

          Regards

            Much thanks for your input Phil.

             

            3. Yes, I can see that in CPU-Z, the DRAM frequency is 800MHz, so it looks like it's good. Thanks.

             

            4. I reset to defaults in the BIOS, but it didn't help. I'm able to adjust the inlet fan speed without issue, but no matter what I set for the outlet fan values, it spins at maximum speed.

              For issue #4, regarding the outlet fan at 100%, I've been told by an Intel representative to try resetting the CMOS. Is this any different than just going to the BIOS and resetting all BIOS settings there? If resetting the CMOS just resets the BIOS to default settings, how would that be helpful?

                Hi

                 

                Did you go into the classic view and reset your BIOS to defaults from the home page of the classic BIOS view? That was how I got my fan speeds working again after a BIOS update, of course this might be a different issue.

                 

                Yes removing the battery will clear the settings.  Of course resetting to defaults should do the same thing, but if the defaults aren't updated correctly to reset everything then clearing the CMOS will certainly do that.

                 

                Regards

                  Thanks again for your reply, Phil.

                   

                  How do I switch to classic view? I checked all the BIOS options, but don't see it. I did reset the BIOS settings and I also tried a CMOS reset, but neither of them fixed the issue. Outlet fan is still running at 100%.

                   

                  Any additional suggestions would be most appreciated.

                   

                   

                  Thanks,

                    Hi guys. I have exactly the same problems with the Fans speed and starting IDU on my DH77EB board. I saw several threads on this forum where were described the similar problems on the other Intel boards. Many people advise to reset settings in the Classic BIOS mode. But I also could not find how to switch to Classic mode BIOS. Where is this option?

                    Thank you.

                      In Visual Bios there is a button at the top saying "Classic Mode" or something.

                        I don't think DH77EB has Visual Bios at all (fortunately).

                        The fan speed issue can be worked around by sticking the fan into front fan header. This at least is regulated in 0071.

                          I agree that "I don't think DH77EB has Visual Bios at all (fortunately)."

                           

                          For the second, I have 2 fans on. Now I have to endure the noise of rear fan and wait intel to release a new bios.

                            Hi. I see the mouse cursor in my BIOS. It looks like Visual BIOS...

                              Hi AGluk, you might want to search YouTube for "Visual Bios" and see what it looks like.

                              The Intel site seems to link Visual Bios to Z77 chipset only.

                                Hi ulo_77.

                                 

                                I know how the visual BIOS should look. I have MSI Z77A-GD65 board on the second computer. But I also saw the old BIOSes - AMI, AWARD, Phoenix and I know that there is no mouse cursor on them. They are all worked in the character mode. But this BIOS is 100% graphical and with mouse cursor. Maybe it was done similar to character mode, but it is graphical.

                                 

                                All the same thank you
