We were very interested in seeing what Epox would do with the nForce3-250 chipset. Epox has a history of building motherboards that are extremely fast with a very wide range of tweaking options. Frankly, while we were impressed with the features that Epox packed in the 8KDA3+, we were quite unimpressed with the mediocre range of tweaking options when we received the Epox. However, Epox persevered and the board improved dramatically over 2 BIOS revisions during our testing. The latest BIOS for the 8KDA3+ provides a very competitive range of tweaking options and it also turns out to be an outstanding performer.



Epox uses their same ugly green trademark for the 8KDA3+, so this is not a board for case modders who demand color coordination. The full-size ATX board is generally well laid out, however, with plenty of room around the CPU for even the largest heatsink/fan. Since this is a board that might find its way into a tower case, we should point out that the floppy and IDE connectors are very low right on board. This is not the best location and will cause a reaching problem in many case designs. Epox is the only board in the roundup with 6 PCI slots, if that is important to you, but the price that you pay for this feature is possibly having to remove very large video cards when you want to change memory. There is also the Epox 2 digit LED trademark that provides diagnostic read-outs to assist in troubleshooting.

Epox does use the latest Gb chipset, so you have both on-chip Gigabit LAN and on-chip Firewall. There are no firewire connections, however, but these can be easily added with a PCI card if you need them. Both Optical and Coaxial SPDIF connectors are handily located on the back IO panel. Epox also has used the Silicon Image SiI3114 controller instead of nVidia's accessory chip. The 3114 supports up to 4 additional SATA drives with standard RAID 0 and 1 plus the option of RAID 5 and 10. RAID 5 and 10 provide options for a Hot Spare and on-line mirror rebuilding to the 4 SATA drives.

    I'm a little surprised to see why the MSI K8N didn't get the gold compared to the Epox. Both seem almost identical in every way, except that the K8N seems to include Firewire. Shouldn't this feature make it surpass the Epox board?

    The only downside of the MSI board seems to be the limit of a 300 max FSB, which is probably fine for 99.99% of overclockers.

    Thanks for link, but my KV8 Pro still wont boot when selecting "fixed" in bios setup.
    Why wouldn't my board have the pro chip? Manufacturing screw up maybe?

    Bank Interleaving is not an option in any of the BIOS' tested here. Many current BIOS enable Bank interleaving by default. Where it is an option, we definitely enable the best interleaving option available and list what we set in the memory chart. We are not ignoring this option.

    If you are looking for the latest Abit KV8 pro bios have a look here. http://www.bleedinedge.com/download/bios/abit%20am...

    multi support and PCI lock inc. if your pro board won't lock the pci bus with this bios then your board may not have the pro chipset.

    Well after finishing the article, I was wondering why none of the boards are run with bank interleaving on? Doesn't it increase memory performance for the ones that support it?
  • Myrandex - Friday, May 28, 2004 - link

    On the KV8 spec page, it states:
    Onboard USB 2.0/IEEE-1394 8 USB 2.0 ports supported by nF3-250
    No FireWire

    Should be K8T800 Pro instead of nF3-250.

    What revision of KV8 Pro were you using and what bios version?
    Nobody else with a recently purchased KV8 can get the locks to work. How come your board does?

    Anandtech should have looked at the problem that the Chaintech VNF3-250 has with it's RAID and installing an OS, and the problem where the board refuses to boot from SATA if you enable RAID on any IDE HDDs. People've said they've been able to circumvent it, but I haven't got it to work yet, and Chaintech is worthless when it comes to customer service. I received an automated response about 6 or 7 days after my initial submission on their website (they have no US phone number.) And I still have not received an email from a representative yet.

    If there's so little variation in system performance between these, why not look at other aspects like USB throughput/CPU utilization, IDE/SATA throughput, ethernet throughput/CPU utilization, etc.

    Ace's Hardware just did a great article showing that the rather crummy components being used these days on cheaper motherboards have a pretty large impact in performance in those areas.
