The GA-8KNXP and Ultra boards are available and in stock today. The Ultra has onboard SCSI Ultra 320. The best price so far is $389 at www.fticomputer.com

i just got my 8IK1100 today (its the "lite" version of the 8KNXP)...so far so good...
only problem that i have is the memory dividers...with a 400mhz FSB P4, i only have 2 options...one is 3:4 ratio and the other is auto. i cant seem to find the ratio so i can run my ram synchronus with the FSB (ie. 1:1 ratio)...
if anyone has any ideas im all ears...
btw...ive already updated the BIOS to the F5 bios...still only have those 2 options

If you mean you want to run your RAM at 400MHz(PC3200), you can't. It's a chipset limitation.

I thought the canterwoods couldn't run the 400fsb P4's? Only the 533 and new 800's.

Wrong.

 

[TenEgg]

well, what ratio do you get when it's auto?

according to the BIOS...the divider is set to 3:4 when i choose auto...the BIOS tells you what your memory speed will be when you select a divider (in other words, the BIOS does the math for you)...so no matter what FSB im at, its gonna have a 3:4 ratio applied to it.
according to the manual, im supposed to have 3 options with a 400FSB P4:
1:1, 3:4 and auto.
i only have the 1st and last option in my case. ive already emailed gigabyte tech support about this so hopefully ill get a reply back from them soon...

i think you understood the question incorrectly...the P4 bus is quad pumped...which means you multiply 4 by the FSB. when i said synchronus, i meant the value of the FSB before it is quad pumped. so...100FSB (which is actaully 400mhz quad pumped) with 1:1 ratio is ddr200 (cuz for the memory...its 100mhz x 2 since its ddr).
btw...this chipset does support ddr400 operation so you were actually wrong and right at the same time.

I'm a little embarrassed about asking this, but I think I know the answer. I'm currently running a P2-400 machine. I have decided to upgrade to a new computer. I decided on the Gigabyte 8inxp motherboard. I got it and it was DOA. :frown: So I sent it back for a refund

So I was looking and realized the next chipset, the 875p, came out. So I figured since gigabyte was bring out this board in the next few weeks, that I would wait until it was on the market.

I was reading the message on the web site about how this new chip isn't much faster than the 845 chipset. So I'm looking at getting at least the 8knxp board for now and for future growth. I figure it will last me a very long time.

So I guess what I'm asking is since I'm making such a big upgrade, that I should just go with the 875p for long term growth.

Thanks for any replys.

It only supports DDR400 @ 800(200x4)fsb.

 

[jaeger66]

Newegg has 8KNXP and 8KNXP Ultra in stock.

 

[harddrive747]

Yep, however, the price is 250 for the 8knxp and 399 for the 8knxp-ultra.

So I'm going to wait a few days and perhaps weeks to see if it will come down.

See ya

 

[Badash7]

Can you use the 8knxp ultra without the dps2 plugged in? I haven't tried it yet on my 8inxp.

... 400 dollars for a mobo... i thought 245 was alot



Badash7... yes u can... i have never had my dps in... no reason really

 

[GetInMyFatBelly]

But that $400 includes Ultra SCSI 320. How much would a motherboard + a Ultra SCSI 320 card cost you?

 

[Bobbyeyes]

the gigabyte site claims that it is 320 mbs of data transfer,but they say nothing about 64 bit controlling.
i hope it is not a 64 bit scsi controller soldered on a 32 bit pci controller.
if someone purchases this monster , i would love to see some atto results
this mobp is my next purchase if it is 64 bit

What's the difference? It's not like you're going to get much more than 75MB/s out of your drive anyway.

 

[Bobbyeyes]

um... server boards have 64 bit pci slots to take full advantage of hard drives like mine:
ibm
seagate

You're missing the point. The fastest hard drive on the planet, the Seagate Cheetah 15K.3, tops out at 76 MB/s. So unless you have 3 of them in RAID 5, you don't need a 64 bit bus or even an Ultra320 controller.

 

[Bobbyeyes]

oh!...now i see.!!
a 32 bit bus, and a 64bit bus w/ a 320 controller will give the same data transfer(someone should tell TYAN and all the other server mobo manufacturures)

you know what.....
given the choice of a 32 bit/64 bit bus-w/ a 320 controller...
i think ill take the 64 bit bus.-especially w/ hyper threading!!

You obviously don't get it. It doesn't MATTER how much data the controller can transfer because the drive will NEVER be able to reach those speeds. Put the Cheetah on an Adaptec 19160 and it won't be ANY slower than on a 64 bit/320 card. If you can't grasp this, you probably shouldn't use SCSI at all. And this isn't a server board.

w0w :Q... didnt know they were that pricey... $177 is the lowest pricewatch had for a Ultra SCSI 320 card...

alrighty then! research helps...

 

[Bobbyeyes]

jaeger66...
that odd... it says that it is a server board on the web site.....
i better hurry up and sell all my scsi systems and hard drives!
thanks!

That's probably a good idea, since you really don't have the faintest idea what you're talking about.

 

[Bobbyeyes]

i REALLY dont have the faintest..
i even thought this thread was about the potentially fantastic
GIGABYTE GA-8KNXP board.

when i buy this board i will give a detailed (thugs format) thread.. including ide vs scsi performance, and overclocking and memory performance results.
so jaeger66...
i might just have to hold on to my scsi drives just a little longer!
