VIA KT400 <----> nForce2 ?? Need help.

nCaine · June 30th, 2007, 03:36 PM

My goal is to reach 2.4Ghz/FSB 400 (my cpu can handle it with no probs) I waiting for Chieftec PSU also.

Ok i have Asus A7V8X mobo , with the VIA KT400 chipset and i just found out that this mobo is missing the divider FSB:PCI =1:6.
At 166 the fifth divider kicks in to give a stock PCI freq. of 33MHz and AGP of 66MHz (166 divided by 5 = 33). Once you get to 180 those buses are at 36/72 and as you go higher , are im in troubles ???? Probable when i wuld hit 200 , hdd data coruption wuld happen ??

The thing is that i probable gonna be able to swith this mobo for some nForce2 chipset for free. I heard that they lock the PCI/AGP buses at the proper frequencies while VIA lets it float proportionally with the FSB.

Im noob when it comes to motherboards .Culd some one point me some mobo on whit i can do the FSB 400 , with my rig . And also wuld be good if this mogo wuld fully suport DDR400 and FSB 400 not "unoficialy" like my asus ombo.

hi ncain
via is shity chipset but nforce 2 is really good
i have it and you can go on 200 fsb without any problem but to find mbo with nForce2 ultra is hard
there is few models with that chip
have puted a Asrock mbo in my old case
its good but bios dose not have that much functions
ASRock Motherboard - Product - K7NF2-RAID - Overview
i had before ASUS and MSI mbo in it
ASUS is good overclocker but MSI have much more equipment on it
try to change your mbo for ASUS A7N8X-XE
ASUSTeK Computer Inc.
this mbo is fucking great

p.s.ASUS and Asrock is a same firm

if you change your mbo for asrock mbo
shut down a raid controller it is making tooooo long load(boot) of windows

Thx mate for quick anser , i diged in to problem and wanna ask one thing more.

On almos every forum about my search , i stubled upon discusion about what is better
mobo with a lock pci or mobos with the FSB to PCI/AGP dividers.

They say that nforce2 are "safer" , but others say that you can get better performance out of the dividers.
Wonder if some one will help me with that question

when its locked fsb for pci/agp you cant burn your cards on it
if fsb is unlocked you can allso clock a agp port and it will give you small boost but that is risky to play with
on most nForce2 mbos you can set up a fsb manual for cpu/ddr and that will not affect a PCI/AGP speed (and you can rise a PCI/AGP speed allso but only manual and this is good thing)
and i think that ASUS can unlock buss ratio so you can change it from 11 to 10.5

Cool , so it will be with locker , but about that ASUS A7N8X-XE , i reded many opinion that its lack OC`ing option in BIOS , or was ther some good bios updates ??

Update : i just read that the last upade dint bring nothing new. And that its the poorest nForce2 mobo from asus. hmm

Update2:ther is a modified bios for that mobo that has voltages setings and other options that the A7N8X Deluxe. But thats not good idea.

you can finde moded bios for this mbo
asrock allso cant change multiplier (dident tray anyway but i get 215-230 fsb without any problems) but over that it crush dont know why cpu and chipset are cold

gen.Rage1991hrv · June 30th, 2007, 04:52 PM

lol i dident see this in bios LOL
i was thinking that cheap mbo dont have this

Link is broken. NF2 is great.
