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

[4rory]

right now im running bios 1.95r2 modded by murdok, I just use clockgen to change the multi in windows, works fine.

[FatRakoon]

I just bought one of these boards yesterday... I expect it to be delivered on teusday ( Hell waiting that long )

Now too sure how my current RAM sticks are going to cope in it. I have read that some have a few issues with this or that RAM, and I suppose I am just thankfull that I have a number of systems, so I am sure that I have somethign that will behave enough to get me started, even if I wont be clocking just yet.

The RAM I have in line for it right now, that I will try out first, is Crucial balistix 3200 and I hope it will be ok. I have touched 224MHZ on the DFI LP with my XP17 on with that RAM, but as I say... I wont clock this PC for a while.

Failing that, I have Corsair XMS3500, however, I have 1 x 512 and 2x256 and apparently, its not too hot with using 3 sticks,and in all honesty, I would rather have 1GB or RAM at stock, than any kind of clocking and half the RAM.
Plus I have got my XPM running nicely at 236x12 with that RAM, so its staying on that anyway.

So, can anyone tell me something if they would?

How does this Motherboard, with a Winchester 3200 compare in real terms, to a Barton 3200 in say, an Abit NF7S? ( Stock everythings )

How does it compare to an XP17 @ 216x12.5 ?

And

How does it compare to an XPM @ 236x12

I just fancy knowing what I am in for?

Thanks all.

hi FatRakoon

I have crucial ballistix 4000 but they are the same memory chips as the 3200. they work well with the neo2 in 1:1 settings im currently running mine at 260 at 2.5-3-3-10 @ 2.85volts.

I do have issues when using the dividers though and its possible it could be the ballistix so when you try yours see what happens in 166 mode compared to 200 mode and let me know.

I upgraded from a DFi lanparty nf2 and mobile xp at 2.5ghz 250x10 and the performance improvment with the neo 2 is noticible probably due to double the memory bandwidth.

[4rory]

The new bios fixes the divider issues which was cause by using tighter trc and trfc values when using a divider.

[sideeffect]

Thats not the only problem with the dividers trfc and trc dont make a difference with stability in my setup. 166 just doesnt work very well. Im using 1.8r2 bios at the moment which sets trfc and trc to 15 and 13 on boot and it doesnt make 166 divider stable.

[harpyboy]

compare using A64T, when you are using 200 and 166 divider.. That will give u a clue of what timing are different.

Guys,

I need some advices on my overclocking.

I'm using my system at 246x10 = 2460 MHz, 166 divider, resulting in 205 MHz at 2-2-2-5. The system is fast with this speed, Primed, OCCT passed, etc..., and the vcore is 1.52v.

So I tried 240x10 = 2400 MHz, with the memory 1:1 in 240 MHz at 2.5-3-3-6 (I did 4 loops in Memtest, ok for that speed) but I've tried a lot of different vcores and the CPU is unstable. It can't run 2 minutes on Prime, locks on games, totally unstable. I tested from 1.4-1.6v and nothing!

What might be happening? Why did the CPU can handle 246 but can't 240? My HTT is configured to 4x, and I don't know what else I can try. I'm using BIOS 1.8mod.

Does anyone have any idea?

Thanks a lot!

My best results with my venice 3k+ & neo2 & corsair 3200XL is that :

HTT 3x
cpu : 8.5 * 311 @ 1,54v (1,7v in bios 1.9b5 mod)
ram : divider 166 > ~240mhz - cas2.5/4/3/6 @ 2,8v

Test your settings with relaxed timings ... CAS 2.5 / Trcd 4 / 3 / 6 @ 2,8v
The 260mhz full sync' @ 2.5/3/3/6 run fine with me ... (but in asynchronous mode I have best results)

Moreover, I think isn't good idea test with Prime/OCCT/MemTest to prove the stability , use the PC in your games/apps about 2 days and if all are okay it's good ;-)

to ocz booster and mushkin bh5, what is the best bios??

Thanks Sonic, I'll try relax a little. About the RAM voltage, 2.7v seems to be allright (according to Memtest), but I'll also try 2.8v.

Did you notice any better with BIOS 1.95?

Thanks!

[Sonic9]

I have tested 1.8 (mod & un-mod) , 1,37mod and finally the 1.95b5mod and I havn't notice better results ... I havn't all tested the settings ... For one month I have the venice&neo2 ... I will search again the good settigns !

Goodbye.

[LittleDevil]

Im using 1.8r2 bios, but cpu voltage over 13% 15% 18% don't work.

tnx

[4rory]

Anyone know what all the memory timings in the new 1.95 bios do? Especailly the MTRR or w.e.

[Blinkme323]

This is hands down the best bios I ever used.

^^^^ You stole my memory tweaks from other post

[Blinkme323]

Lol, they worked well. You got anymore?

How about an A64 Tweaker screenshot of your most stable, highest clocking memory settings.

guys I need some emergency help, last night I tried some settings that worked the week before but suddenly this week my pc has been acting funny, not allowing me to overclock much on settings I've ran before and I've been having to reset my cmos if that happens, so last night I decided I would try again to see if it would work and right around 2.4ish I get no post from my pc and attempt to reset the cmos only this time even after resetting my cmos I get no post at all, I've checked my psu's (not sure about them as they turn on automatically once they get power) and I've stripped apart my pc today and put it back together only connecting the essentials and it still does the same thing, psu turns on automatically, shut it off manually via case switch then I turn it on properly via the case switch yet no post, also from the D-Bracket it shows that it is "Decompressing BIOS image to RAM for fast booting".

So I come to you guys for help, is there anything you can think of to try or what the problem could be and why this is happening?

THANKS A BUNCH!

[harpyboy]

it is weird that ur psu turns on automatically. it shouldn't unless ur BIOS option set it to after a power failure.. was this PSU doing the same thing as before ? ie starting up auto ?

if u hav access to another computer.. test ur PSU over there to verify.

otherwise it might really be a burn chipset.

any others opinions anyone else?

[uniacid]

No my psu wasn't doing this before (at least when I used them in single mode, with the dual psu connector I have one will turn on if the other isn't already powered) if it is a burnt chipset how could that have happened, it was working fine and I wasn't even pushing it much, if this is the case do you think there would be any problems with MSI warranty and any idea how long they usually take?

[STEvil]

mine turns on automatically too.

Its a problem with how the board circuitry was laid out.. something connected to the power on circuit is too low of an impedance and causes the PSU (which is built to spec) to think the power button has been pressed.. and so it turns on.

What you probably need to do is switch the PSU off and remove your cmos battery for about 5 minutes.. should give enough time for most or all of the power in the board to drain and your BIOS to clear. If you have a PS2 keyboard you can hold the insert key down (DO NOT LET UP UNTIL YOU CAN SEE A POST SCREEN) then press the power button to power on.. it tells the bios to post at default settings.

USB keyboards dont work for this when an overclock setting fails..

didn't notice u r using 2 PSU inline. im sure u tested it with just 1 PSU rite?

hhmm... did u check ur motherboard to see if there is any burn stuffs on it ?

[uniacid]

Thanks STEvil I'll try that and yes harpy I tried 1 psu, right now my X-ultra since my other can't power my pc + gfx card alone

[uniacid]

forgot to say that no there are no burn smells on the mb, and STEvil how long should I have to hold the ins key down? b/c so far no go
