Re: DH55HC Problem

1st: There is 3 different ways to update the BIOS for this Mother Board. Intel has a nice video on there web site on how this is done. Search Intel's site for your "DESKTOP BOARD" then look for your "BIOS UPDATE" INSTRUCTIONS can be found in the read me notes. Do not remove the BIOS jumper since this will cause BIOS settings to change from what you may have customized. Leave jumper on the normal position termials 1 and 2. Note don't update BIOS unless you know the problem is covered in the updated BIOS. See below.

2nd: (Your problem with the Memory Control Hub temp I don't have a answer for that since I have not ran across that problem) and have not needed to research it. I will suggest make sure you have Memory that has been approved for use with your mother board, and the latest chipset driver.

To identify your current BIOS version, check the BIOS version string:

During boot, enter the BIOS setup by pressing F2.
Check the Main menu.
The third segment of the BIOS Version (a 4-digit number) is the current BIOS version.
Press Escape to exit BIOS Setup.

Example BIOS ID string showing the version number:

IMPORTANT:

Update the BIOS on your computer only if the newer BIOS version specifically solves a problem you have. We do not recommend BIOS updates for computers that do not need it. You can view all new BIOS fixes in the Release Notes included on the BIOS download page in Download Center.

Downgrading the BIOS to an earlier version is not recommended and may not be supported. An earlier BIOS version may not contain the support for the latest processors, bug fixes, critical security updates, or support the latest board revisions currently being manufactured.

Before initiating a BIOS update, be sure to read and precisely follow the update instructions. You may wish to print the instructions for easy reference.

If a BIOS update process is interrupted, your computer may not function properly. We recommend the process be done in an environment with a steady power supply (preferably with UPS).

All images in the examples used in the instructions are specific to certain desktop boards and are for illustration purposes only. You need to select the correct BIOS files for your desktop board.

There are up to six methods of updating an Intel® Desktop Board BIOS to the latest version. The number of options made available for any particular board may vary, depending on drive support and BIOS update file size. You only need to use one.

All BIOS update files for Intel® Desktop Boards are available on Intel's

Refer to this matrix to see which update method will work for you.

1The Express BIOS Update is the simplest and most common method of updating a BIOS.

2 The F7 BIOS Flash Update is available on Intel® Desktop Boards beginning in 2009. To see if your board supports this feature, in BIOS Setup, check the Advanced > Boot Configuration menu for the setting Display F7 to Update BIOS.

3 The floppy disk methods may be used only when the BIOS update files are small enough to fit on a floppy disk (smaller than 1.44MB) and if the desktop board includes floppy drive support.

Re: DH55HC hdd led always on

Simple answer for this is move the HDD Led to terminals 2 and 4. Terminals 2 and 4 are Alternate "Front Panel Power LED" This will then show HDD usage, instead of a constant on LED as you described using terminals 1 and 3. While terminals 1 and 3 do say "HD LED" and have a "+ and -" reversing the wire should not make a difference since its a simple "LED" or element. and if you ground here to the chassis you will damage the Mother Board. LED needs a return to the mother board + an - so it will light up. As I stated terminals 2 and 4 are alternates for the front panel LED, and will make the HDD LED or front panel to blink instead of staying on continually. Observe polarity which should have been provided with your tower paper work, but I don't think it matters since it's just an element. I had the same issue and this did solve the problem.

Re: H55 chipset: why not simultaneous integrated + discrete graphics?

In the Tech notes it states specifically if you install a PCI Express x16 card the on board graphics are disabled automatically, along with the HDMI output. Thats the way the Mother Board was designed. There is 3 other options for a Dual-Monitor set ups. The first way is to take advantage of Intels Dual-Monitor set up is you have to use the on board graphics with either the CRT connector or the DVI-D connector and then you can use a HDMI cable to a TV set that has HDMI input which gives you Dual Monitors. A second way is to invest in a PCI Express x16 with Dual out puts. I'm using a eGeForce 8600GTS 256MB with Dual DVI out puts "Works perfectally". The third way would be to use the two PCI Express X1 slots which would once again give you Dual monitor out puts but you would have a investment of two graphics cards. I would recemond you check the vendor of the graphics card you are interested in and see the FAQ'S for that vendor to check compatibaly for your Mother Board with Intels chip set. Of course you will need the latest drivers for your graphics card to make this work correctly. And finally I will be checking myyself for a different graphics cards so I can use the two PCI Express X1 slots the Mother Board provides which once again gives you two connections for two monitors. I'm using XP Pro SP2 with all of the updates to SP3 from windows and eGeForce, and I have no problems. The box my Mother Board came in states Dual Independent display for procesors with Intels Graphics Technology.My Mother Booard is the DH55HC and I have a i5-650 Dual-Core Processor. The LGA1156 Scoket for this Mother Board supports many different Processors as long as they are LGA1156 pagkage socket. I have the i5-650. Other processors supported by this board are the is and the i7 and i3. I can't wait to check out the newer PCI Express x1 sockets, which I will put graphics cards in both of those sockets. So I have given you three different ways to get a dual monitor set up.
