-=Dfi Infinty&LanParty Rev B Faq and more=-

[Revv23]

coop ive had both and infinity and the lan party are the exact same board with just different feature sets.

trodas, your information is awesome... no one has really done that much research into the extra timings... its something ive always wanted to do, but i later find out that the board has "moods" meaning sometimes youll get tight timings and high clocks, and other days itll only boot if you underclock it.

as a status update im no longer able to overclock on mine as i didnt put enough thermal paste on my NB (i know, dont beat me up about it, im retarded) and it wont run in dual channel anymore, not to mention it takes 3.0v to get 200mhz single channel 2-3-3-7.

anyways good luck guys, not sure why you guys are buying new old hardware, especially now that there is some new stuff on the market to play with like the RDX200.

Hi again guys. Im happy that reply someone

Mine problem looks good. I set up 1+3 dimm and reput cpu in socket.
Prime was testing 15h @1,65v ok.

But i have problem with high fsb.
250 fsb , 1,9vdd, 3,3 dimm, (1,5, 1,6 1,7 agp the same ) 11-2-2-2-13-15 auto
Pc freeze by 3d aplications at in menu .

I have the chance buy lanparty ultra B. May i do it or its exactly same and its no point get 250 fsb Prime stable without mod ?

Guys which one is the most stable and best bios for this board for overclocking?Any links??

ex.treme - caps on the mobo failing like mad. Replace them with good ones, see: http://www.xtremesystems.org/forums/...ad.php?t=87710
And enjoy the mobo again.

coop - witch screen do you mean, this?

You can run this too on any nForce2 mobo. Tough I having some problems to make it auto-run at every start on XP machines, see there:
http://www.xtremesystems.org/forums/...ad.php?t=75664
If you mean BIOS screens, then check there mine screens:

Revv23 - the "mods" are all about bad caps, trust me on this. I bet that when it is new, it don't have "mods", right?
Your caps is gone, man. Entierly. That it is. No question about it. I can run 200Mhz FSB 11-2-2-2-7-12-0-0-3-3-2-0-3-E-E-F-E w/o heatsink on the NB stable. 512MB Mushkin Lev I 2-2-2 Hi-Perf stick.
Thanks for the timins, next thing to do is look out for the Strenght and Slew rates. Adding them to nForce2 tweaked could save one days of rebooting, tough...
Same as adding support for 7-12 instead of lovest 9-12 alpha timings in the Hellfire rev.3 one...
And old HW is sometimes fun to play with - and you got a PM

ex.treme - you need new caps, and not mods. You cannot expect to run FSB 250 with old and mainly bad caps...! See later.

LoWRiDeR - the mighty God SAE says Hellfire rev.3 and I agree. There you go:
LANPARTY B Hellfire bios rev. 3 - best one!

And now finally a explanation why and how does the Taiwan and China boards differ.

First at all, let me say that all the time DFI fierce fully deny that there is any difference. Now I got my hand on Taiwan made mobo, and having two China made ones already, I spotted quite a few differences. First at all, the CPU mosfets is slightly different. On both mobos are there two series by 3 for each one of them. The first is 09N03LA and the second ones (closely to the CPU) are 06N03LA. But on China mobo are these 09N03LA - BC335 and 06N03LA - AN330, while on Taiwan mobo they are 09N03LA - CG339 and 06N03LA - AA330! And even by the very first look, they are different - the 09N03LA - BC335 on China mobo have a bit rounded edges, see there:
http://ax2.old-cans.com/s.php?p=badt...6&c=8&d=1&v=v2
...while on Taiwan mobo they both having sharp edges.
So, there is visual AND a little specification difference as well. Now let's move to the Vdd/Vdimm mosfets. As expected, the differences did not ended up with Vcore mosfets, but the very same differences are in these as well. China mobo use (looking at the image link bellow, from left (Vdd mosfet) to the right (3 Vdimm mosfets) 09N03LA - BC335 and 3x 20N03L - VF328 while the Taiwan one use probably - mosfet destroyed, anyone could help there - 09N03LA - BC335 (?) and 20N03L - XR320, 20N03L - VB320, 20N03L - XR320.

While some might say that these are quite small differences, it is indisputable that these are DIFFERENCES in fact, witch prove DFI lying about it. (no wonder at this point, the manufacture policy surely will deny any differences on principle, it's logical...)

And now for the main event. At the very first glance at the Taiwan made DFI board I noticed the (except the Made in Taiwan is not blanked with white anymore) caps are different. Yes, the 5 main ones (Chemi-con KZG ones, 3300uF 6.3V) and the there 1500uF 16V by same brand are the same, but the rest is different from what I have on my China ones. Upon a close inspection I found to my HORROR, that these caps are Teapo ones! Now for these who aren't familiar with Teapos - they are known as bad caps brand. Definitively bad. They die. Theirs good specs in short time get worse and worse and... and the mobo become unreliable. For anyone think that I was not right, then see there:

God help the mobo...

Now conclusion - what all this means? Well, since Taiwan mobos are praised for their overclocking results, it obviously mean that the choice of the components for them was better - at least for the time being. ST caps specs can't stand against Teapos (well, for the time being it get reversed, but at first... amazing OC was possible!), witch explained the overclocker rumors about better Taiwan boards.

So, recommended action - replace immediately ALL the Teapos with some good brand caps (Samxon GA (when become available), Nichicon HZ, Rubycon MCZ, Chemi-con KZJ, Samxon GC, Nichicon HN, Panasonic FM) and then just enjoy your board back on rock-stable and reliable operation.
Even that I did not find anything better that the Panasonic FM ones (http://digi-key.com has them, still looking out for either Nichicon HZ or Rubycon MCZ for extreme OC), my mobo started to work reliable and as soon, as I add also the blocking caps, I try some OC and post results.

But definitively and finally, the mystery is solved. Taiwan mobos are at start notably better for OC that China ones. Later they suxx much more that China ones, since ST aren't bad brand of caps, though their specs suggest why the China ones clocked lower that the Taiwan ones did.

If anyone can provide me better caps, I still have 2 DFI mobos waiting for recapping, we can measure the differences. Even if I have to buy a oscilloscope


To get any idea, how bad are those caps, the look there - the SEK specs:
http://www.teapo.com.tw/ftp/pdf/SEK.pdf
Teapo 1000uF 10V 12/02 A3 SEK 105°C - impedance 6 - ripple current 400 (1000 hours) 8x15

Not too bad for general purpose caps, but use these cap for filtering Vdimm voltage?! Insane at best!


The OST then (if they are OST) are a bit weird, since I can't find a RLF cap with the dimentions the ones I see on my board has - 8x15mm and 1000uF for 10V. Weird. The most closest one have this specs:
OST 1000uF 10V RLG O352 105°C - impedance 0.18 - ripple current 615 (2000 hours) 10x16 (8x15 they are!)
Rest check there:
http://www.ost.com.tw/docs/newost/pdf/RLG.pdf
...however it is also marked as bad cap...!

Now this is ironic or something...

Let's compare it with Panasonic FM (worsest of the better caps brands):

SEK 1000uF 10V - impedance 6 - ripple current 400 (1000 hours) 8x15
OST 1000uF 10V - impedance 0.18 - ripple current 615 (2000 hours) 10x16 (8x15 they are!)
FM 1000uF 10V - impedance 0.026 - ripple current 1790 (4000 hours) 10x16
