I'm the owner of an 8KNXP. I really like the board's features
(especially the IDE RAID), and that was my primary motivation for
buying it. Unfortunately, my first 8KNXP randomly died after ~8
months of otherwise perfect use. I received a replacement (RMA) board
(another 8KNXP v1) in about ~2 weeks.
The replacement, like the original, feels fast, and generally runs
well. (There doesn't appear to be any major sign of impending doom.)
I would, however, point out a few of the issues that I've noticed:
1) The PC speaker beeps randomly, despite the fact that the fan and
temperature fail warnings are turned off, and temperatures are easily
within spec. Solution: I had to unplug the PC speaker. (Gigabyte
tech support claimed to have never heard of this problem before. No
pun intended.
2) The Northbridge fan tends to be quite loud. It often "grinds" with
a horrific "death wail" on start-up. The noise does go away after a
while, but I wouldn't be surprised if the fan one day stops spinning.
Why the 8KNXP comes with a NB fan when most of the other major vendors
use passive cooling is beyond me.
3) There have been a number of discussions about various memory
incompatibilities with the 8KNXP (and especially older BIOS releases).
I must admit that I've never had any problems -- I run a
dual-channel, 1GB OCZ PC3200 EL RAM setup with 2-6-3-2 timing, and
everything's great. Supposedly, the 8KNXP version 2 board (which is
probably what you would receive if you bought one new) has cleared up
a number of these problems. But, like I said, I've never had any
problems in this regard.
4) The "spontaneous" failure of my first board doesn't seem to be a
one-time thing: there have been a number of posts in this newsgroup
from people experiencing similar difficulties. (There was no evidence
of failure -- no leaky capacitors, no stopped fans ... The system
simply would not boot or post.) That makes me very suspicious of the
quality of the product, as a whole. (I mean, failure after the first
few days or weeks -- sure, I can accept that. Failure during a bout
of heavy CPU-intensive usage -- sure, I can accept that, too. But in
my case, it was a random failure when the system was essentially idle
for a few hours -- sheesh.)
All told, my 8KNXP is my first -- and definitely last -- Gigabyte
product for some time. My next board will be from Asus -- I've never
had these kinds of problems (nor heard of any of my friends/colleagues
having problems) with that brand.
