Intel DH67CF _ noob questions

Hi, I have decided to get the Mini iTX mainboard DH67CF.

Can I ask you some questions please ?

 

 

a) Can you recommend either of these RAM modules for this board ?

 

1. G.Skill F3-10600CL9D-8GBNT (1.5V)

2. G.Skill F3-10666CL7D-8GBECO (1.35V)

 

 

b) I intend to use the Intel i5 2500K CPU.

Would the BIOS allow me to underclock and / or undervolt the CPU ?

 

 

c) I used to have two monitors in use (extendet desktop).

Can I plug in one via DVI and the other one via HDMI at the same time ?

 

 

d) The board has 4 SATA sockets. Two 3GB/s and two 6GB/s.

Can I still plug 3GB/s devices into all four sockets ?

 

e) I want an SSD drive for the OS.

Which ones are the best Intel SSD drives (under 100 GB) currently ?

 

f) I guess this mainboard has no bluetooth on board, is that right ?

 

 

Thank you very much!

    Regarding your questions,

     

    a) Intel does not provide specific product recommendations, so I would not be able to assist you with that question. You can find the motherboard compatibility information here:

    http://www.intel.com/support/motherboards/desktop/dh67cf/sb/CS-031961.htm

     

    b) The BIOS will provide some options to change the voltages on the processor, yes.

     

    c) Indeed, you can use both the HDMI and the DVI ports at the same time.

     

    d) The SATA-6 ports are certainly backwards compatible with SATA-3Gb/s devices.

     

    e) If you would like presales information, please feel free to contact us over chat:

    f) Indeed, this motherboard does not support Bluetooth.

    Hi Jose,

     

    thank you for your reply.

     

    to a) ✔ For RAM modules to work, they do not have to be specifically designed for a particular chipset. That's what an admin from the G.Skill forum told me the other day.

     

    to b) afaik the default voltage of the i5 2500K is 1.15V

    It has been undervolted (different mainboard) by someone to 1.025V, I read somewhere.

    Another user managed to undervolt the CPU to 1.016V while keeping the default frequency.

     

    Would you know how far I could actually decrease the voltage with that mainboard ?

     

    to c) ✔ ok

     

    to d) ✔ that's great because I would not like being limited to only two SATA ports.

     

    to e) ✔ I have decided for the Intel 230 Series 80GB, SSDSA2CW080G310.

     

    to f) ✔ ok

     

    Thank you very much

    The motherboard should allow you to set the voltages to something close to the lowest supported voltage for the processor itself; however, we never recommend changing those settings in the BIOS, as they can cause the processor to malfunction.

    Hi, would you know how many 3-pin fan headers are on this board please?

    According to the specifications there are 2 x 4-pin PMW headers, but no mentioning of any 3-pin headers.

    Thank you

    The board doesn't have voltage control of the CPU Vcore, unless they added it recently, only DRAM and GPU are present, but both do nothing at all, because all motherboards share same bios but not all the PCB components needed for the voltage change to occur. Mine H61WW can only control DRAM but not GPU, and there are reports that H67CF can't control dram.

     

    The 2500K default is 1.2660V, measured 1.200-1.232 depending the load. and that is way to much, the CPU only needs 1.05V. Be prepared, not possible to undervolt. Please contact the department of bios writers to add this simple bios module while compiling the bios as it is common to all motherboards but is considered overclock, so it didn't see light for cheaper models initially. It is still not too late to add this option to control CPU Vcore Down from default many people will appreciate it.

     

    If you intend to use Dual channel, expect problems, look for the latest revision of the board that adds a capacitor to stabilize Dram.

    Cov,

     

    In answer to your question, CF has two 4-pin fan headers, one white and one red.

     

    The Processor Fan header (the white one) is specifically intended to be used with a 4-pin, PWM-controlled fan, such as that included with Intel boxed processors. If you do plug a 3-pin fan into this header, it will spin just fine (and be monitorable), but its speed will not be controllable (i.e. the fan will always run at full speed).

     

    You can plug either a 3-pin fan or a 4-pin fan into the System Fan header (the red one). The keying tab on the connector will ensure that the 3-wire fan is oriented onto the correct 3 pins. The board includes a special circuit that can detect what type of fan is installed and will manage it accordingly. If a 4-pin fan is detected, its speed will be controlled via the PWM signal (the 4-th wire in the connector). If, on the other hand, a 3-pin fan is detected, it will be controlled via voltage scaling.

    @ spearson _ Hi, thank you very much for your detailed explanation.

     

    @ Nipo _ Hi, thanks for your comment & suggestion. Sorry for the delay, I was thinking a lot before I decided to reply. AFAIK default Vcore of the i5 2500K is 0.97V (idle) and 1.190V (load). Some people were able to undervolt the CPU to 0.82V (idle) and 1.05V (load).

     

    @ all _ does anyone know how to contact the department of BIOS writer, where I could suggest to implement the undervolting feature for future update? I'm aware that Intel apparently does not like users to tinker with certain settings, but as a user I do not like to be patronized. I want to decide on my own whether to accept the risk or not. Many other poeple made positive experiences with undervolting.

     

    ► I wonder why this mainboard still uses liquid electrolytic over solid capacitors, although it uses capacitors with polymeric electrolyte for critical knots such as processor voltage regulator circuitry.

    ► I wonder why it uses an AMI BIOS with standard text interface instead of the a modern EFI BIOS like on the Asus P8H67-I.

     

    What I do appreciate on this board is the extensive options for configuring and adjusting rotation speed of the two 4-pin fans, being able to specify parameters describing the dependence of fan rotation speed on the temperature and to determin which temperature should affect the fan rotation speed as well.

    I do like the four (!) thermal diodes for CPU, RAM, CPU voltage regulator and chipset.

     

     

    There is another important question I need to ask you all.

    ► Is this motherboard only supposed to work together with a push-pin CPU cooler like the default one?

    I ask because there seems to be a problem when using a CPU cooler with backplate.

     

    Here is a picture of DH67CF's rear where this chip (circle) gets in the way:

    This is a picture of a typical backplate:

     

    http://www.abload.de/img/1xufx.jpg

     

     

    That chip could prevent the DH67CF to be used with a backplate as can be seen here (different mainboard):

     

    http://www.abload.de/img/5duky.jpg

     

     

    My questions is whether anyone can confirm that this kind of problem is still existing with revision 3 or maybe not?

     

    Thank you very much in advance
