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

Booted with 133 and set 166 with a64 tweaker and still the same errors. So it seems that 166 just doesnt work for me.

The 183 divider is more stable but im not sure if its fully stable yet ill test that now :cool:

The 1.95 beta bios is supposed to be more stable with the 183 divider but doesnt have the option in the bios atm but it has the registers in the bios so it seems that it will be added when the final is released.

However i have never been able to get 1.95 beta bios to load bios setup it boots and loads windows ok but wont load the bios setup menu in dos tried msi beta and murdoks rev1 2 and 3 with no luck. Other people have had this same issue though so hopefully this will be fixed in the final revision as well.

Guys, what BIOS has the 183 divider option? I'm using the 1.8mod and it doesn't have it.

Thanks,

AleX

nothing pre 1.95 does I should say.

Might want to try moving fans to different headers if the bios screen wont show for 1.95. Abit nF7(-s)'s had the same issue which was due to RFI interference on the fan headers.. D27 bios may have been the one with the issue, cant quite remember.

You have to set 183 divider with a64 tweaker from within windows. In my experiance its as stable as 1:1 with my setup where as 166 divider isnt stable at all.

yeah, but thats annoying ;)

How true ;)
I've been using a64 tweaker startup settings for a few weeks now, in the BIOS I just select the 100 divider and in windows it loads the 166 :)
Works like a charm here :)
In fact, I don't even care about the BIOS memory options anymore, since A64 can set it all for me :)

Yeh, but all people wannna VID + 18% and for the same price 183 divider too ;)

I see some very positive effects with 5.0ns read preamble. I'm testing it with
my crappy winnie, cbbid, very very poor memory controller :(

289Mhz (2.5-4-3-7) 1:1 ratio@2601Mhz Winnie w\ 5.5ns preamble = winmemtest error at ~ %500. w\ 5.0ns preamble it goes without error forever :)

this was on rev.3 180 bios, so i think 5.0ns is coming in rev.4 Anyone also gets positive results?

I always use 5ns and most screenies i see of a64 and nice tccd clocks are 5ns.

I also think 5.0ns is the way to go, but be careful with that.
I integrated read preamble 5.0ns in one of my bios, but my system wouldn't boot @ 200mhz then, so if you do a cmos reset with rd 5.0ns built in you might no longer be able to boot.

yes 5ns is nice. This will be the last bios that i will release before v1.9 offcicial bios. It's like an improved HH edition:

- 5.0ns read preamble (forget about it :( )
- twr upped to 3 clks (2 clks in rev.3)
- trtw upped to 3 clks (2 clks in rev.3)

what's need to be done:

- DQS, which does better job in terms of stability (faster, slower or off)
- ugh........... the tref value.....headache I believe default is 3072 no?

Many people may reach 300fsb with rev.3 easily, but those who have crappy memory\cpu's mem controller, this bios will be for you. Participate :)

EDIT: @digitalfrost, yes i know about that
EDIT: Oh men, just realized, 5.0 will be no go. hard to boot at 200HTT :(

haha, yes!, beat my personal record on crappy cbbid winnie :toast: so this shows cpu and mem needs a lot of tweaking.

Nevertheless you can integrade read preamble of 5.5ns for the people who use dividers.

To get 5.0ns working we'd need to readout current clockspeed and do an if-then-else, so say, enable it at >=266Mhz, but I don't know how to do that.

yeah, good idea but it seems impossible. In Neo2 bios timings are changed only when divider is present. But hey, wait, how about hack gig lan like tictac and insert code there. Um but that wouldn't work either, gig lan is probably enabled by default no? Only options is to insert code somewhere to some useless option within the bios that is disabled by default

EDIT: We have only one option left, Hack EPA logo; which is disabled by default. Insert 5.0ns read preamble there and once we reach high htt, just enable the EPA logo
EDIT2: maybe make realtek gig lan disabled by default using modbin :) ??

How measure tension meter electric vcore? Where on mainboard? Which places in? Please give me some snaps, because otherwise, I will not apprehend... :P

PS. Sorry for my english... :)

Great bioses NFM :D

sorry to interrupt... jus here to say good effort guys !!!

sorry i can't participate... too busy with my exams now.

gambateh !!!

Yeah thats easy. But integrating the code in nic.rom I have no idea how this stuff works.
I already looked at tictacs file using disassemblers but I don't get it.

Enigma: Take a look at the VCore mod thread, maybe there you will find a picture http://xtremesystems.org/forums/showthread.php?t=41350

HI:

With my tester in this point I read 0.2v les than "real" vcore I see in bios and windows. Why???? This is the true Vcore mesure poin??

Thanks

Hi all, I read fast reply ... finally is it possible to set DQS Mode to faster ?

Wow is this the XP90 ? I like how it also cools the ram

Its possible with modded bios.

@digitalfrost: Okay fast reply ! I wait THE modded bios with DQS Mode to Faster !!

@NFM: Thanks for your modded bios :-) and in your screenshot, what the multiplier used ? and what voltage ? thanks ! I want 280-290 of fsb sync'ed too ;-)

@Sonic9

I believe I used 7x multiplier, but 9x did the job also. 289x9=2601Mhz stable max on my winnie. v2.8 for my ram, default voltage for cpu at 7x multi, at 9x multi 1.536-1.55

@kasius

Winchesters are undervolted by v0.1, also Neo2 flactuates

So faster DQS Mode proves to be more stable?

My friend use a DFI nf4 and the only stable configuration is done with DQS Mode to Faster ... but for mee I continue to prime my system ... but my brother kill it and plays GTA sometimes argh

@NFM: the Rev3 has 5.0ns ??
