One of the more impressive features the IC7-G brings to the table is excellent Serial ATA and IDE drive support. With two standard Primary/Secondary IDE connectors and four Serial ATA connectors (via Silicon Image 3112A controller and ICH5R) the ABIT IC7-G is capable of supporting four SATA as well as four IDE drives for a grand total of eight possible drives. While most desktop users will find this feature to be nice instead of necessary there will always be those who desire this capability for something a little more potent than everyday desktop usage.

Another interesting feature of note is the TI TSB43AB23 IEEE-1394 FireWire controller that comes onboard the IC7-G. FireWire support is always a nice thing to have, especially if you're a heavy DV camera user. On the other hand, most users simply want enough USB 2.0 ports as their devices more than likely don't require a FireWire interface. Nonetheless, the addition of a rear FireWire port and bracket are very nice, quite good high-end additions for quite a high-end motherboard.

As shown in the picture above the IC7-G contains some excellent BIOS options for tweaking memory performance. Besides the standard memory timings you find on all Intel chipset-based motherboards, there is a "Performance Mode" option that allows speeds of "Fast", "Turbo", and "Ultra", options which are common among VIA chipset-based motherboards. Unfortunately these options are somewhat broken in the IC7-G BIOS, you can only use them if your memory timings are fairly relaxed. Aggressive timings with Performance Mode disabled yields more performance than relaxed timings with Performance Mode at "Turbo", so we suggest you shoot for the lowest memory timings possible when configuring your IC7-G. Still, it's nice to have options if your memory modules happen to be incapable of CAS 2-3-2-5 or lower.

Another nice BIOS option comes in the form of an adjustable AGP/PCI option available as high as 96MHz/48MHz, which is more than enough for even the most hardcore overclockers. The IC7-G's Vcore range is easily the most intriguing feature of this BIOS. Adjustable up to a staggering 1.925V, this Vcore is especially appealing to overclockers, as too little a Vcore can definitely minimize your overclock despite the fact that most P4 overclockers can do just fine on default voltage (1.525V or 1.550V depending on your P4 processor). The IC7-G hardly undervolts so you will be able to reach approximately 1.90V in real world usage.

Among the more annoying aspects of the IC7-G are its horizontally placed Primary and Secondary IDE connectors. The fact that these connectors are placed horizontally is annoying enough, as you are forced to maneuver your IDE cables through other cables in your case. What's worse is that the Primary and Secondary IDE connectors are placed below the midsection of the motherboard, meaning the IDE cables that come bundled with the IC7-G may not reach the upper bays of certain ATX cases, especially the high-end ones that tend to be bigger than your standard computer case. This placement therefore forces you to install your optical drives on the lower bays, making the front of your case look fairly ridiculous, though I suppose that depends on how sensitive you are to aesthetics. Another negative aspect of the IC7-G is its very loud North Bridge fan. However, ABIT is currently in the middle of shipping new motherboards with a bigger, quieter North Bridge HSF so this will not be a concern for users purchasing in the not so distant future.

    I bought IS7 after reading this article and I've been having problems. Random resets, then BSOD after changing XP recovery settings. Over the past few months it worsened. In the begining it like once a week maybe. I wasn't concerned, bad driver I thought. Now it won't run more than an hour without BSOD. I have Corsair XMS DDR400 in it. I've played with memory settings for weeks, timings and voltages as well, reinstalled XPPro several times, updated BIOS, got all newest drivers and run out of ideas... I've put a stick of DDR333 because that's all have to test and I still get the same random BSOD, even durnig XP installation. I have no PCI cards in this box. Mushkin calls this board problematic and attributes the memory problems to forced implementation of PAT that is not normally present in 865. I may try getting it replaced by NewEgg but I don't suppose it'll help. I'm thinking about getting a 875 board instead. Zak.

    I would like to see part II of the roundup of the 865 chipset. I wonder what is the delay?
  • Anonymous User - Monday, October 13, 2003 - link

    I thought Part 2 would be out by now at least... There are good new boards out there I'd like to see... Shuttle AB60R (cheap and full featured) and Abit IC7-MAX3 (OTES for mobo power area). I am still looking forward to seeing this, eventually, right guys?

    Any comments on newer motherboards? Why hasn't supermicro been tested since 2000?

    Looking to compare supermicro
    Intel s875wp1-e and Super P4SCE (SuperServer 5013C-I (SYS-5013-CI)) for a $50k cluster

    Thanks

    Evan, how in the world is #4 going to research your statement when the articles/review comments forum gets purged/is gone now ?

    Any word on Revision 2 of the Gigabyte 8knxp ultra board yet?

    I bought the is7 after I read this article. It had many problems. I ended up having to ram this board twice. If you read the abit forum boards you will see alot of problems I am fairly surprised after all the tests this board was put through nothing ever went wrong. I will not buy another abit product period. I will stick to gigabye i've built 6 systems with Gigabyte and yet to have any problems with them. Save for the chipset fans having a low life.

    I bought the Abit IS7 and am completely pleased. One note is that many of the IS7's appear to be getting shipped with the gigabit lan as opposed to the sales brochure stated 10/100. (mine has the gigabit)

    How could it be that the Asus p4c 800 de luxe is more expensive then the asus p4p deluxe but in the testresults it is slower?

    I would think i am misinformed by the computershop?

    And the p4c deluxe got a gigabit lan on board, despite mentioning in the summary of this Mb it has not.

    Error Re: Gigabyte GA-8KNXP MoBo
    This MoBo has 4, not 2 SATA connectors, 2 controlled by ICH5R and 2 more contolled by the SIL3112 chip.
