"If you would be wealthy, think of saving as well as getting."

This quote by noted author, diplomat, physicist, and politician Benjamin Franklin describes our attitude about the ASRock ConRoe945G-DVI motherboard. While the Core 2 Duo processor series was launched in late July, the availability of motherboards supporting this impressive CPU has not been stellar. We saw a small wave of Intel 975x and P965 chipset boards at launch that are finally starting to mature from a performance and compatibility standpoint. In the meantime we have seen a few additional boards launch based on these same chipsets, along with others using the NVIDIA nForce 570 SLI and NVIDIA nForce4 SLI X16 for Intel series. We have also witnessed some old now new again chipsets come of age based on the performance potential of Core 2 Duo. The VIA PT880Pro, Intel 945P, and Intel 865 fall into the latter category, and now we add our first look at the Intel 945G chipset with Core 2 Duo.


While the 945G has been around for awhile the performance potential of the chipset is still very good, especially for the budget sector, and provides a solid platform for those interested in a mATX form factor board. The 945G will eventually be replaced by the recently released G965 chipset and we expect there to be an almost $40 difference in price between the two platforms for the time being. Whether the G965 is truly worth this premium or not we will see in an upcoming article.

In the meantime, ASRock recently shipped us their ConRoe945G-DVI motherboard for evaluation. The ASRock board is expected to sell for around $75 and brings with it a full set of features including a separate DVI card that allows for dual monitor usage with the onboard Intel GMA950 graphics chip. While the onboard video is fine for general desktop usage and surfing the Internet, it is not meant for 3D gaming no matter how many buzzwords Intel throws out in their GMA950 specification documents. Our article today is meant as brief review of this chipset's capability as implemented by ASRock when compared to a recent review of other budget chipsets. We will have further performance results from this board and others based on the mATX platform in a future roundup.


The 945G chipset used by ASRock in their ConRoe945G-DVI motherboard is over a year old, and it is paired with the Intel ICH7. Our first impression of the motherboard was very good as the layout of the board is clean and well organized for a mATX design. The chart above lists the standard feature set available when utilizing the Intel 945G (82945G) and ICH7 (82801GB) chipsets. The 945G/ICH7 combination enables full support for a single X16 PCI-E graphics slot or onboard GMA950 graphics configuration, a single HDMR slot, up to six X1 PCI-E devices, 4GB memory addressability, and native DDR2 533/667MHz memory support. This combination also enables support for eight USB 2.0 ports, HD Audio, Gigabit Ethernet support, six PCI slots, four SATA 3.0Gb/s ports, and two IDE devices. The 945G chipset does not support the Pentium EE or XE series of processors.

Now let's take a closer look at the performance this board offers.

    With this board in order to overclock higher than 299 you either have to do the CPU,PCIE Sync which will allow you to go up to about 130-320 before you knacker your SATA drives or you can set it to CPU,PCIE Async; set PCIE to 117 (no effect on system) and then you are able to go up to 350 (runs a 6400 @ 2.8 gHZ). Don't forget that at these speeds you are also overclocking your memory so open up the timings before you try it.

    Hello... I plan on using this budget board as a transition board until the Lanparty series for Conroe is released or more OCing board options arise. My only concern is that, while I will probably use it stock with a E6600, I want to make sure my Geforce 7950GX2 fits in it. I read the Epox 945 MATX review on Hard and they mentioned that that card did not physically fit in that board. Any comments about this would be greatly appreciated. Thanks!

    Are the overclocking shortcommings of this board (cpu core vlt/memory vlt)correctable thru possible future bios updates?
  • JarredWalton - Tuesday, September 5, 2006 - link

    Possibly, but I wouldn't count on ASRock making the changes. Most of their boards have the same BIOS limitations and have for a while now. :|

    I sure home ASUS gets there P5B-VM to the market place soon. I want to get my hand on a good MicroAtx Core 2 Duo board so I can upgrade my Ultra Fly SFF system.

    I have bought a pretty similar board recently - Asus P5LD2-VM SE. It is a stripped-down board, but for a real bargain. I also have Core2 E6400 (8x, 2.13GHz, step.B2) and 2x1GB Corsair XMS2 675MHz-CL4.

    I've been trying to overclock this configuration and was able to reach 297 MHz FSB stable (2.37GHz CPU, 742MHz 4-4-4-12 memory, both stock voltage). The board has quite good CPU/memory voltage setting capabilities, but I wasn't able to post after 299 MHz. Any suggestions?
    What is the best memory timing for these Corsair modules at such a high frequency?
    What is the maximum safe voltage for CPU and what for the memory? (I didn't try to push the voltage much higher to not destroy the thing).

    I have the board for a month now, for a month overclocked and must say it was worth it. But if I could achieve even higher overclock, it would be really nice :-)

    Thanks again AT. I always enjoy reading your articles and they usually have most of what I am looking for. Like others before my post, I too want to see power consumption. I am looking for a solution to put in my car as I will be fabricating a carputer in the coming months. Seeing as how I expect the Core Duo to last, and I don't want to upgrade my carputer for years to come, this probably will be the solution pending the power consumption of the mainboard coupled with the CPU. It would be nice to get some comparison along with the Centrino line processors, as well =)

    Although the DVI riser card is a great idea (and gives the the possibility of dual monitors) it seems like the sensible thing to do would be to have a DVI connector as the standard on-board connector. You can always use a DVI-to-VGA adapter if necessary, and those must be cheaper than the riser card. Anybody with enough cash to go dual-screen can buy another cheap card, or better yet, a card with dual DVI output.

    I know most of us interested in mATX boards are especially interested if a board includes two particular things:

    Component video output (for onboard video)
    SPDIF audio output

    Future roundups should include whether or not a board has these features.

    Well, owning an Asrock motherboard I feel compelled to speak up on the subject. While my motherboard is an Asrock AM2NF4G-SATA2, I have a feeling the feature set (minus the DVI card) is probably pretty much the same. After one months times of owning this board, I would have to say that it is a well thought out board in most respects.However, that being said, there is a few things of concern relating to this board as well.

    1) As stated in this article, The Asrock AM2NF4G-SATA also has limited memory, and vcore adjustments, which is probably to be expected in a budget motherboard. I was however able to eek out a 16% OC by dropping the multiplier to 11x, and raising the HT to 250MHZ. Raising it any higher caused system instabilities. Dropping the multiplier further resulted in a lower OC, which I felt wasnt worth the time playing around with.

    2) Setting up a SATA as the boot disk on these motherboards seems to be borderline un-exceptable. First, you must go into the BIOS, and change the SATA operation mode to [RAID], enter into the RAID BIOS utility, identify, and set the drive as a 'spanning' (JBOD) array, and THEN either have a driver slipstreamed copy of XP, or have a floppy attached. To make matters worse, these steps are not in the manual, and after talking to technical support on the phone (email technical support is shyte, until you get an actual email address from a rep), it took me several hours of trial and error, to figure out the proceedure. Another thing to note, is that these steps must be followed if you expect to run XP setup with a SATA attached period, whether its the boot disk, or not, otherwise you'll have to disconnect the drive, and re-attach it afterwords.

    3) Stability seems to be an issue on this system, although, this could be attributed to software, I'm still trying to iron out the details (yes, after a month). Its hard tracing the problem since the system seems to randomly reboot, once every 2-3 days, and its a hard reboot, with no BSoD. I suppose this problem COULD be related to another peice of hardware, I'll have to figure that out.

    Anyhow, I would like to know if the problems (except for #1) I've experienced with my motherboard, hold true for this motherboard as well. I would like to add, that for the price, this motherboard is probably well worth it, once you get used to the odd behavior, and realize that this motherboard wont OC very well (should be known to begin with anyhow), it could prove to be a decent motherboard. I'll just have to keep testing the stability issues of my own, and on a clean XP Pro install, so far (in about 18 hours) no random reboots.
