An interesting feature that Gigabyte has included on such motherboards as the 8INXP (E7205 chipset) and SINXP1394 (SiS 655 chipset) is Dual Power System 2 (DPS 2). This is a separate, add-in card that gives the 8KNXP 6-phase power circuitry instead of 3-phase. Gigabyte claims that, in Parallel mode (versus Backup mode), DPS 2 is able to deliver better system stability (especially while overclocked) in addition to longer onboard components life.
It should come as no surprise that Gigabyte continues to incorporate dual BIOS chips even though the 8KNXP Ultra is a workstation/server class motherboard. As we mentioned in the AOpen AX4C Max section, having two BIOS chips can be helpful if you've permanently corrupted your first BIOS chip (through overclocking, overvolting, etc.) and so instead of being forced to RMA your board or replace the chip yourself, your board will simply revert to the second backup BIOS chip during your next bootup.
Quite obviously the defining feature of the 8KNXP Ultra is its SCSI support. The 8KNXP Ultra has an onboard Adaptec SCSI Ultra 320 7902W controller that sits on an independent 32bit 66MHz PCI bus (via 2nd PCI bridge), meaning bandwidth is limited to 266MB/s. Theoretically the full 320MB will not be realized, but since the 320MB transfer is only reached in burst rates (not sustained) and will depend on loading (number of hard drives) it won't make a performance difference, as there are very few system apps that will saturate this bandwidth. Still, it is obviously better than sharing the standard 32bit 33MHz PCI I/O that is limited to 133MB/s. Interestingly enough Gigabyte is going to continue improving the 8KNXP Ultra when they release a revision 2.x 8KNXP Ultra in mid-June, which is to incorporate PCI64 66MHz maxing out at 533MB/s. Gigabyte says there will be availability this week or at least sometime this month, but we'll have to wait and see if that turns out to be true.
UPDATE 6/19/2003 We should also mention that you must hold the CTRL key and press F1 to bring up the Advanced Chipset Features section, where you will be able to adjust your memory module's timings.

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.Anonymous User - Friday, October 24, 2003 - link
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?Anonymous User - Tuesday, October 7, 2003 - link
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 ?Anonymous User - Saturday, August 23, 2003 - link
Any word on Revision 2 of the Gigabyte 8knxp ultra board yet?Anonymous User - Sunday, August 10, 2003 - link
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.Anonymous User - Friday, August 8, 2003 - link
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)Anonymous User - Tuesday, August 5, 2003 - link
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 MoBoThis MoBo has 4, not 2 SATA connectors, 2 controlled by ICH5R and 2 more contolled by the SIL3112 chip.
