The OFFICIAL MSI K8N Neo2-939 tips and tricks guide thread

Ok the bios works fine now ill add the cd1986 no temp mod bios to the ftp for anyone else who has the issue.

Just had a little mess around with it the 216 divider now works. Couldnt test the 250 as my main ram is being rma'd and im using pc2700 ram atm. The 3.5 Ht multiplier options has gone, it didnt work in the previous betas but it was there, i guess they couldnt get it working.

Nfms timings set but nfm have you tried to add the 183 divider into the bios? does it have the options in bios. Also twtr (Write to read delay time) sets to 1 with 166 divider still. Please force it to 2 in rev 2 :)

Good job with the bios though :clap:

Rev2 will be out shortly. 183 divider is there but it is not activated. It's like with extra 13%, 15%, 18.3% VID option, they are there but thre's nothing you can do about it :( . Yeah I will remove temps from BIOS so people don't be pissed if something does not work.

Ok, Rev.2 is up. Testing needed.

Changelog Rev.2:

- twtr = 2 clks
- All temps hidden, to see them hold "Shift + F2, hold it still and with your
second hand press "ALT + F3"

---

Suggestion for Rev3 NFM, change what is loaded when you press "load optimal defaults" to some more OC friendly settings. I've found it a great way to save some time once you've cleared the CMOS. Some of the default settings used from the factory are no good for OCing, and we have to keep changing them everytime we reset the bios! :rolleyes:

yes good idea cd1986 im all for that. :slap:

Some ideas for defaults

Ati/nvidia speed up = disabled
boot up logo = disabled
small logo = disabled
S.M.A.R.T = Enabled

Tested the bios and it works. Flashed ok the temperatures are hidden and i cant unhide them with alt shift thing. i see the little flash u get when it supposed to show hidden options but they dont appear.

Twtr still defaults to 1 in 166 divider also. The rest of the timings set ok though

maybe you set read to write instead of write to read :slapass: :p:

; Write to read delay(dth)
twtr_data equ 0FFFFFFFEh ; Write to read delay (1bit)
twtr_1 equ 000000001h ; 1 clock
twtr_2 equ 000000002h ; 2 clock

yeah i probably messed up with that one, so many values :confused: :slapass:

Ati/nvidia speed up = disabled
boot up logo = disabled
small logo = disabled
S.M.A.R.T = Enabled

will do that

also i will do:

spread spectrum = disabled
cool n quiet = disabled
agp fast write = disabled

EDIT: Rev.3 is up

twtr still defaults to 1 in dividers. Maybe it doesnt work or maybe the code is wrong. Oh well not a big problem really.

The bios is really good the default settings work nicely and i can enter bios setup which is always a bonus :) I cant get the temperatures to show but that might be my problom alone as i have the issue.

Someone else try and unhide the temperatures.

Good work NFM going to use this bios from now on.

Well i tried 1.98 and i have to say it is still in beta phase. Don't know why did they post this bios on korean msi. I'm switching back to 1.8.

how bad is it ?

Its not bad its just not official. Somethings dont work like after more testing the 216 233 and 250 dividers dont work. The northbridge fan control isnt included. There are no .5 cpu multipliers.

The bios seems pretty much stable now though and my overclock seems ok with it as with the 1.8.

I dont think there is much point upgrading to the bios unless u have a san diego or a x2 processor.

I lose my USB 2.0 capability. It only has USB 1.1???

Yes usb 2.0 support isnt added yet so not i good idea to try this bios if you need usb 2 :D

But can I get the same overclock i'm getting on 1.8mod cuz befor 2.9 wasnt stable on 1.95, I need the memory options my ram is almost stable and it would be a killer 24/7 setup, 2.9ghz with 7500+mb/s :banana: , but I need better memory options to finish it off.

What you could do is that you let A64 tweaker automatically load the timings every time windows starts...
(I do it this way, always start up with the '100' divider and let A64 tweaker do the rest)

lol that causes instand crash, I can't even change more then one setting in a64 tweaker without instant freeze.

A64 tweaker is a windows killer waiting to happen.

for you to have someone start ram at 100mhz and then A64 tweaker INSTANTLY kicks the ram in tha arse and forces it to make in instant jump up to insane overclocked speads WHILE in windows is foolish to say the least.

many people wont be able to do this as it will simply lock their system.
i dont recommend anyone try this unless they have 100% stability with their overclock via the bios and booting into windows.

you could potential damage your systemand corrupt windows beyond a point of repair if the system crashed.


I NEEEEEED someone to test something for me

1.9 bios any version most importantly the supposed actualy bios from the MSI site and also NFM's modded version.
You MUST have adjustable rails on your PSU in order to try this.

1)
adjust your 12v+ rail above 12v maybe 12.5v
2)
adjust your 3.3+v rail past 3.3v 3.4 3.5 3.6

now boot the system.
Are you having the same issue i am having ith the 1.9 bios that the system will NOT boot to any media. no matter what you do it posts fine it goes thru the NVRaid detection fine and whatever else you may have, and then it might read the floppy like its gunna start but nothing happens.
Same for a CD like the XP boot cd. it says "press any key to boot from cdrom" then either nothing happens OR it says "checking system" like the xp cd does when you boot to it but again nothing happens.
same thing with the Hard Drive.
It will flash the HD light but nothing happens.
You can press F8 and choose safe mode but nothing happens.
If you have linux it MAY boot to the linux kernel argument options screen but nothing will happen after that.

the only way to fix this is to reduce all voltages down to damn near the exact voltage they are said to be,, ie; 12v 3.3v 5v

even after doing that i am having SEVERE issue trying to boot to a floippy to reflash the bios. roughly 1 out of 20 reboots will then boot ot a floppy where i can reflash with the 1.8 bios.

Also,

can anyone else chime in on stability or other issues with the 1.9 bios. ?
and has anyone of you modding gent's even TRIED to allow the bios to go above 2.85v on the vdimm ?
the hardwarelock on these boards is what ? 3.0v if i remember correctly and frankly gents... I NEED 3.0V this OCZ EL Gold Rev2 PC4000 cant even go past 260mhz STABLE ( and i enphasise stable) without more than 2.85v
this is good ram and will reach 1:1 ratios of 290mhz if you get a good kit.
My last kit did 311mhz STABLE on a 9/10 divider but i had to have a minimum of 3.0v to do it.

also the 183mhz mem divider. we all know thats simply the 1/2 cpu multiplier setting. thats why its in a reserved state.
Simply remove all 1/2 cpu multi's and any instance or mention of it in the bios and then remove the reserved setting in the ram divider section and one would think it would allow the ram to run at the 183mhz divider
yes ? or has MSI made it more complicated than that and its more of a hardware issue than a bios issue.

http://www.swjka.com/neo2/view_thread.php?fid=3&tid=13
with this Bios, i have only 3000 MB/s Readspeed @ everest. With 1.8 Bios i have about 6000 MB/s. WTF?

hoohhhhh... tat's pretty weird... anyone has this issue ?

seems like dual channel is gone

Any particular line of RAM could have different types of chips in them depending what was available on the market at the time. Sounds line you may have RAM that was produced from Winbond dies, the older set most likely being BH and the newer most likely CH. BH is well known for not booting into CAS 3 but will do 2.5 or 2.0 with proper voltage. Get that vDIMM up into the 3.2 to 3.3 range and you may find that your RAM can do 2-2-2-5 at fairly high speeds (~250MHz). I know the MSI board will not do that voltage. A vDIMM hack or OCZ DDR booster would correct that issue for you.
As far as having four double-sided DIMMs populating your motherboard's RAM slots...this will always cause your BIOS to revert to DDR333 speeds. Search these boards for much of this knowledge being repeated over and over ad nauseum. OK, I'm done here.

Hoping for that new BIOS :shrug:

ok first up, i have 2 double sided sticks (2x512).
second up the chips appear to be one revision different. i dont recall the first letter but the two are: xb and xc for the chips. not sure what letter replaces the "x" but the 2nd letter for one is "b" and the second letter for the other is "c".

so idk. they are def diff revisions just dont understand why 2x doublesided is dropping it to 166? esp since each individually does 200. and it seems wierd that it happens in all combinations of using the 2 sticks together.

i have set the timings manually as i mentioned in my original post. basically the ONLY problem is the 166 drop from 200. timings wise i can run the faster timings with both sticks in at the same time no prob. so yeah why is it dropping back to 166?

look at this. :O

/edit
Wahhhhhhhh, PC1600. What the F

Go into A64 Tweaker and see what Max Async Latency says. and Tref
Controller mode also. And clock frequency
128bit should be dual channel and 64bit single channel (i believe thats correct, the single channel part i mean)
The first 3 things i just mentioned if they arent set right will just absolutely kill your ram thruput.
basically if you have a screen shot of what your settings were before. go into it now and compare them to see whats going on.
also CPU-Z see if its showing the proper settings. CPU-Z will tell you if its Dual or Single channel on the Memory tab.
and yes it does sound like Dual channel is gone.
but also set the ram chips like every other mobo in the world.
Slots 0 and 2 dual channel and slots 0 and 1 and 2 and 3 are single channel.
in other words first slot and 3rd slots. just for the heck of it try it. see what happens.
again reflash the bios again with the same rom file and see what happens.
im telling you guys this 1.9 bios is FUX'd BIG TIME!!
whom ever is programming it at MSI is a bunch of blooming retards.
Also does this same thing happen with the actual 1.9 bios from the korean site ? or IS that the korean site bios ?

I think you've got your wires crossed?
1&2 or 3+4 = Dual channel.

Msi

Can someone please!!...tell me the best bios for my setup??
I have problem to run my memorys in 250fsb (2-2-2-8) 1:1.....I now they handle 258fsb (1:1) 3.3V on a DFI board!? :confused:

Now I use v1.8.

Thanks..

dual channel is activ, but my RAM is adjusted as pc1600. I have switched in the Bios to Auto Mode and now I have 5600 MB/s (PC3200 speed again). :)

But Speed was better with default 1.8 Bios and same timings. :(
