pros
very stable vcore up to 1.90v read the tips to see how to get 1.9v
vdimm overvolts to 2.90v on highest setting
VTT tracks automatically, OCZ DDR-Booster works up to 4,0V (put it in ram slot 4)
runs great with ballistix
runs great with tccd memory
runs great with bh5 (needs bios 1.36b or newer)
2x Memory Interleaving?
 
cons
cpu socket position problematic for some cases
vdimm mod requieres trace cutting
SATA ports 1 and 2 are not locked, use slots 3 and 4 (closest to the cpu)
issues with ram slots 3&4 not working very well seems to work fine for some people
cpu temperature reading not working correctly seems to work fine for some people
doesnt like ocz eb
 
TIPS
TIP: you have to disable cool n quiet when ocing
TIP: Cpu fan header must be connected, if not the pc could experience boot problems
TIP: if you have problems booting with BH5 try another stick of memory and set vdimm to the max and make sure you set the cas latency to 2.5 or 2.0 as bh5 wont boot with cas 3.0, then swap in the BH5
TIP: the CPU backplate is hard to get off on the MSI ... just heat it with a hair dryer, it will come off easily then
TIP: for best performance the MSI only needs Vdimm/3.3V bypass mod (or the OCZ booster).
Yet to try a chipset mod or HTT mod on the MSI ... it may help with LDT 4x @ > 260 HTT bus speeds
TIP: shut down core center after you used it to adjust or check your settings, if left running it might crash your system
TIP: if you have problems booting at low temps with a winchester try the latest beta bios
TIP: disable fast writes
TIP: only bios 1.36beta and 1.37beta allow up to 1.9v vcore
TIP: color coded ram slots are different than other 939 boards. Slots 1&2 are the ones nearer to the CPU and are dual channel
TIP: use HTT multiplier 4x up to ~260 and 3x up to ~290
TIP: use the + and - or PgUP and PgDn keys to change the htt speed, DO NOT HIT ENTER
TIP: check out the official msi 939 neo2 tips and tricks guide thread
TIP: check out this 2 ram compability lists: 1 2
TIP: In the bios press and hold Shift+F2 and then press ALT+F3 to unlock "hidden" features within the BIOS
TIP: If anyone has trouble getting low temp readings downlaod the latest MBM5 (use the K8N NEO Plat mobo selection, click settings,temps,CPU,and choose the first option for Winbond Diode 2)
TIP: if you experience problems with Antec Neopower and Truepower PSUs and also with PowerStream PSUs, try Bios 1.37 and turn the PSU off after you shut down, seems to help as well
TIP: Dissable Agressive Timings in Cell Menu if you're going to overclock
TIP: some people had close to no thermal compount on the nb, if your nb runs hot add some thermal compound (WARNING! might hurt your warranty)
here is a guide that explains how to remove the nb heatsink
TIP: The MAch II needs a new firmware to operate with this board get it here
TIP: the vcore of winchesters seems to undervolt about 0.1V, max vcore for winchesters is 1.7V
TIP: bios collection: 1.10, 1.20, 1.23, 1.25, 1.30, 1.33, 1.34, 1.35, 1.36, 1.37, 1.41
TIP: beta biosses
TIP: 1.37 modded bios by Trats 1 2
TIP: lots of biosses, incl. beta and modded ones with changelogs
TIP: bios flash guide
TIP: windows tool bios flash guide
TIP: newer boards, with S/N:K0411xxxxxx and S/N:K0410xxxxxx, seem to no longer have a bug with winchesters at low minus temps
TIP: get Codered's A64 tweaker
TIP: if you have BH-5 memory use the A64 tweaker and lower the timings as described here
TIP: OC Guide for the msi k8n neo2 by XS GraveDiggA
right click save as and open with wordpad
TIP: corsair xl pro memory wont fit in the board with an xp-90 or xp-120 heatsink
TIP: the newer northbridges (0410/0411) seem to need less vdimm to reach the same overclock in 1:1!
TIP: If you are having trouble getting windows to boot from SATA ("Error Loading Operating System" ), be sure to set SATA1/2/3/4 RAID to "ENABLED", even if you are not running RAID
TIP: older bios revisions need the agp speed set to 67mhz to lock it
TIP: disable aggressive chipset timings (performance mode) when ocing
TIP: if you boot with trcd 2 vdimm seems to drop 0.1v, boot with trcd 3 and use corecell or codered's a64 tweaker to set it to 2 in windows
TIP: bios 1.36b and 1.37 and modded variants seem to work best for bh5/bh6
TIP: to reach 1.9v vcore set 1.5 in bios + 3.3%, then get in windows use core center all the way up, and finally you use NF3 Clock-gen add 0.05v...it's about like 1.9v
TIP: turn off NV/ATI Speed Up in the hidden bios settingsas it ocs most cards gpu

pros
tracks vtt
marche bien avec la bh5
marche bien avec la  ch5
marche bien avec la mdt pc3200 (micron chips?)
marche bien avec la samsung tccc
 
cons
bad vcore, unstable and fluctuates between 1.70v and 1.95v under load
coldboot problems with high HTT speed
crashes when upping the HTT speed too much at a time
always detects ide drives at bootup, cant disable this setting latest bios fixes this problem
9x multi sligthly unstable seems to work fine for some people
8x multi very unstable seems to work fine for some people
NO Memory Interleaving?
 
TIPS
TIP: you have to disable cool n quiet when ocing
TIP: easy vdimm mod with 3.3v rail = Vdimm Via single wire, VTT tracks automatically
TIP: easy vcore mod with pin10 to ground via 50K VR
BUT the max vcore after a mod is 1.95v and coldboot with 1.85v+ vcore might kill the board!
TIP: If having problems with BH5 ram, try the following:
1) Do 3.3v = Vdimm mod
2) Set HTT multiplier to 4x and HTT to 230Mhz - Lower HTT does not boot for some users.
3) Boot and overclock via clockgen, and tweak via A64tweaker.
TIP: for best performance the giga board needs Vcore and Vdimm/3.3V bypass mod (or the OCZ booster)
TIP: disable fast writes
TIP: use HTT multiplier 4x up to ~260 and 3x up to ~290
TIP: disable the bios option called "top performence" , it will limit your ocs and will cause instability with tccd at ddr400 2.0-2-2
TIP: if you have problems with some multipliers try the F5 bios

pros
runs great with ocz eb
runs great with bh5
runs great with ballistix
runs great with tccd
uses the 5v rail to derive vdimm
port80 diagnostic display
 
cons
problems with 512mb sticks latest bios seems to fix this
WARNING! do NOT use the ocz DDR booster on this board! vdimm above 2.8v will fry a mosfet and kill the board!
coldboot issues, random crashes and freezes from usb hardware (mouse keyboard printer etc)
cant run command rate 1t in slots 1&2 latest bios seems to fix this
vdimm is stuck at 2.7v and wont rise seems to work fine for some people
cpu temperature not reading correctly seems to work fine for some people
vcore ovp at 1.9v
only memory without a heatspreader will fit in slot1 with an xp120
 
TIPS

TIP: SATA ports 3&4 are not locked, use slots 1&2 (closest to the agp slot)
TIP: if you cant get command rate 1t to run try memory slots 3&4

pour la Gigabyte K8NSNXP-939, je fais tourner sans ventilos (DPS et Chipset) avec 1.7v et FSB 280
 
overvolt en burn de 0.05v
 

sympa le post
J'ai la MSI K8N Neo2 Platinum , je confirme : une bonne mobo
Quelsques changements que tu dois faire :
 
-overclocking options
Bus Speed: 200-450mhz in 1mhz steps  
 
Pour l'instant , Le FSB max que j'ai pu atteindre : 283Mhz en 1:1 avec de la A-Data PC4000 . J'ai pu atteindre 290Mhz en synchro mais pas stable @ 2,7Vdimm .
Curieusement , ça n'a rien changé pour moi de passer le Vdimm @ 2,85v .  De plus , les timings RAM ne jouent quasiment pas dans les benchs memoire Sandra lorsque j'ai juste une barrette installée .  
En revanche , la différence de performance entre le mode 1T et 2T pour la ram est très importante : 1T donne 96% d'efficacité sous Sandra , 2T à timings egaux donne 74%

autant mettre direct le lien du topic sur xtremsystems...

Y'a aussi la k8ns qui est pas vraiment différente de la K8NS Ultra

 
pour parler français sur un autre forum, qui est anglais en plus..?

 
Oui c'est exactement la même que la Ultra sauf qu'elle n'a pas le DPS

flag

 
je vois que tu as rajouter la source c mieux  

oui j'avais oublié et c'est vrai que c'etait moyen de pomper sans y apporter des infos supplementaires.

et la ga-k8nxp-sli vous en parler pas sur le topic?
elle est en 939 aussi. voila

les cartes meres en nf4 je vais en parler, le temps de récup les specs.
