Saw this on post 178

You just won't get 2.1V stable (minimum) as these boards can give 2.08V stable max... and that's with all the mods

Is this tru? I will only be able to get 2.2? No way no how?

Looks like some one did 2.15 with a
47K variable.
:stick:


Mine can do 2.24V. You only have to be able to cool the board and its components!

Thanks Sae I appreciate the feedback :toast:

@ tictac

I love you m8...

i was having trouble getting 200x12.5 stable on HF last bios, it just kept getting worse every day, so i load up your bios, figuring WTF? and i got 200x12.5 with 1.825vcore and stock nb/ram/agp, something i couldnt do with 1.9v for some reason just a moment ago, hopefully your bios will be more consisent the the HF bios, as on the HF bios my clocks just got worse and worse it seemed like.....

thanks again!

indeed your right sir, i go to plug in my cdrom as to run memtest, and 250x10 no longer goes into windows, and 200x12.5 hardly stays alive in windows for long, so i unplug my cdrom and the problem is still there...

just when i think im making progress...

ok so heres a very strange issue indeed:

for those not following my situation - so i had it running 272 2-2-2-11 2x256mb cpc on 3.6v about 2 weeks ago, i lost that oc, and i figured it was just my board actung up, as 250 was stable...

so then i lose 250, and eventually 200...i switch to tictac's bios, and 250 works, i plug in a cdrom to run some memtest, and bam, 200 at 3.3 doesnt even work...

...so i tried everything (including reseating) and i couldnt get 200mhz stable even at 3.3v

so i decide to put in my 1gb KHX3000 set into banks 1 and 3(also BH-5)

i ran that fine up to 235 mhz 3.3v and i knew the board was fine, so i was sad and i figured my good BH was dead...

i decided to run them each on their own to figure out which stick was bad, and bam, both sticks run 250mhz 2-2-2-11 cpc 3.3v on memtest5 stable...

i pop both sticks in (tested in all banks and got same results with single stick) in banks 1 and 3, as this is all my cooling setup permits and poop, 250 3.3v get 20000+ errors, and 200mhz 3.3v get about 500 errors..s

so im at a big wtf right now, im really happy my ram isnt dead, but this sucks, wtf is going on here?

try a different ide connector, try slots 2+3, swap ram around so whichever is in 3 is in 1 or 2.

Typical issue of DFI NF2! All I can say. I mean, I don't know it in such drastical way (200MHZ fsb not stable), but something similar.

Sometimes I got a stable 269MHz at 11-2-2-2-2.0-12-16-e-e-f-e-2-0-3-3-1-0-3, I could even do superpi32m, and then next day I had problems running a stable 260. Hehe, seems to be weather-dependant ;) (and may reflect the mood of the board :D)

stealth17
02-11-2005, 06:37 AM
yeh i have the exact problems and some days can get 200 stable! others days i can run 272 semi stable! It pisses me off how its like that! i want to switch to nf4...its either switch to nf4 and sell my old stuff and not have phase-change or its stick with what ive got and get phase change....anyone shed some light on my problem?

Revv23
02-11-2005, 06:50 AM
ok so i eneded up remeoving all my ram sinks (i spent days making them :()

and running in 2 and 3, problem didnt go away...

few more hours later, much more experimenting, turns out i had too much voltage for 200mhz, but these dimm that used to run 200 at 2.6 no longer will(needs 2.8 now), and 250 i couldnt get stable as 3.3v wasnt enough (something these dimms used to do well)

so i memtest 240 for a bit, no problems, and now im back at 250, somehow not erroring at all with 3.3v

funny how im happy to get this right now and im not even at my old 24/7 clocks lol...

SAE
02-11-2005, 11:03 AM
Seems to be the board, my khx bh-5 first did 260@3.34V, now they were demanding 3.56V (my standard voltage). If I decreased vdimm it went unstable. Weird nf2. :D

vdd
vdimm
vcore
OCP

and all were a success! the ocp was the hardest as there isnt much room to work and the pads are a pin points distance aways from each other but i nailed it! i cant wait to see the results with my new OCZ 600watt dual rail psu!

weird man i dunno what happened. the thing worked for a day, then the next day (today) i turned it on and cpu voltage was going from .5v to 1.7v and wasnt letting the thing boot...i was like WTF??? thenit would sometimes boot and freeze in bios...so i was getting upset...put a different psu in and same thing...then i put it on the bench and something by the cpu socket burned for no good reason! i have no clue what happened...especially since it worked for a day flawlessly!...

hmmm im upset with DFI..

so im ganna RMA it and get my FOURTH motherboard and then sell it....more than likely will buy a NF4...you get your NF4 yet SAE???

Too bad you could not locate the error...

And no, I did not get my board, as I ordered it - together with my FX - and they're waiting for it to arrive. *sigh*

And then, I would be still waiting for my sweet vid card I'll get from saaya (I'll pay for it - don't ask him for one :lol: ). Hope my waiting won't last forever and a day... it's a pain!

one of your solder joints could have gone bad on the ocp maybe? that mod scared me way to much, i cant afford buying the irons that would make that job easy, i just have cheapo $5 iron with a big fat tip lol...


new info on my board, i got 10.5x250 rock stable at 2630, so then i backed off the multi to 10x, and i went for 263, now ive been keeping the vdd at 1.8 because more didnt seem to help, but for some reason it just started working, at 1.9vcore, 3.6vdimm, 1.8vdd memtest had 20k + errors, so i up the vdd to 1.9 and bam, 20errors at 3.4vdimm, more vdimm doesnt help, nor does more vcore, so im plugging my vdd mod back in now...

quick question, is it safe to run without a videocard for the purpose of checking voltages? my 9800p cooler sits right on top of monitoring points...

some more good news ot slighlty, upon remounting my 9800p cooler with better screws, and the vmod off, i hit 450core without artifact in 2k1, previously 430 was max... :) almost at 22k with this thing, and thats only with 250mhzx10 on a really bad install of win xp.

im getting excited, i used to think this board was quirky but now more and more i am learning about it the more i realize that there is a reason for its behaviour, i really didnt expect such a large project when i performed these vmods, but im sure glad i did, as ive learned much! :)

bah i went all the way up to 2.2v and couldnt get it error free in memtest, with the mod on im setting it to 1.7 in bios giving me 2.0v...

couldnt get 263 stable unfortunatly, i think i need to tweak as to have .5 voltages, im feeling like the boardd cant handle 3.6v and 3.55 isnt enough...

last thing is maybe my cpu cant handle the FSB, ive noticed amount of errors seems to be a few lower with slightly more cpu voltage, though more then 1.925 was increasing errors, rigs in my HOT basement now, usually rig is in a nice 60 degree room, and now its in like 75, so maybe thats it...

another thing i will try is maybe going back ot the hellfire rev3 bios... man another sleepless night of overclocking ahead heh...

ive noticed that sometimes if you run memtest and get say 75 errors, then run it again it will give you a different number the second time....kinda makes it hard to tell if more or less voltage is helping...unless the error difference is significant

Yep. Best is: errors equal 0 :D

But if errors during longer memtest sessions occur, there may be a heat problem... cooling the ram better is a good idea ;)

Hey... i just did the Vcore mod on my DFI LPB... with just a pencil trick...OMG... it works :hehe:

tictac Pencil Vcore Mod

1) you only need to pencil down this resistor i mark with yellow color...

2) The resistor value is about 100 ohm

3) pensil it down to reduce the resistance.and you will get higher Vcore voltage

4) i pencil it down to 90-95ohm

5) now when i set 1.55v Vcore in bios i get 1.6V (0.05V overvolt) :D

Tested by me... on my DFI Lan Party B

Happy Tweaking... ;)

@ tictac

What do you mean with "pencil down"? How does this work? :rolleyes:

STEvil
02-28-2005, 11:49 PM
decrease resistance of the resistor because the graphite the pencil lays down re-routes some of the electricity.

just from one side of the resistor to another, start small and then check and see how much voltage your getting, then put more lead on it until your where you want it...

Hello guys, i have annoying problem with my infinity.
I can do till 285 (http://service.futuremark.com/compare?2k1=8419816) 3D stable but is only single channel.
First i had 2x256 hynix d-43 and max 250 3-4-4-x.
All above that = errors in memtest + 3D crashing to desktop.
Now i have 2x256 adata tccd and it is worse...... max 245 3-3-3-x and higher is the same - memtest errors + 3D crash after 5s.
I have tested VDD 1.6 - 2.3V = nothing (5 mhz in single),
alpha all combinations ( more or less errors) slew rate = nothing, Vmem 2.6-3.3 = nothing.
Now i'm waiting for BH6 (256 2-2-2 3.3V tested) but i'am afraid history will reply..
Have someone simillar problem to me ? Is board crappy or fussy or maybe memory bad chosen. I have no idea :confused:

(my english is bad, i now, sorry)

SAE
03-01-2005, 02:15 PM

What can I do? Vcore mod? Vsense mod? Or what?

Prokop, 512MB sticks don't like CPC on at high clocks... especially on NF2. And I heard the hynix chips even cr@p out earlier than other chips with 1T.

Sad but true. 1T won't happen at 250+ with these sticks :(

Ok, but if I set up more fsb then 243 and turn CPC OFF, it shows PCI problem when booting :( I think, that I need more V to the CPU. When I set 2V real is (in BIOS) 1,89-1,95. PSU is LC550W (+12 12,1V real, +5V 5,3V real) => it isn't problem.
I think, that I need vsense and vcore mod. Or not?

Does it bluescreen during windows bootup? Then showing the PCI error...??

Could be an apic problem with your board.

Maybe. I have APIC enabled. May I disable it?

It shows PCI error before windows bootup.
What do you think abou my vcore fluctulation?

SAE
03-07-2005, 03:09 PM
Hmm, can you take a photo of the error message or at least write it down for me...

Is it while windows starts loading, or is it caused by bios/dmi pool ?

Don't worry too much about that fluctuation as it's the reading chip that's "fluctuating" (often).

:D :devil:

PS: the Hellfire bioses seems to be pretty good. I still using his rev1, however. The latest turbo one looking promising: http://www.dfi-street.com/forum/showthread.php?t=789
...anyone tried it yet? :confused: :stick: :)


So, are there any nice results with the latest Hellfire turbo bios so far? :confused: Im a bit confused about the latency thing. What is the original PCI latency? Is not 32...?


7. PCI Latency = 128 clocks
8. EXT-P2P Discard = 1ms

I mean - for CPU benchmark - is better to have the latency as low, as possible, right? As well, as the EXT-P2P Discard on the fastest timing as well :confused:

All I know that I gained a lot on hexus PI fast, when I set the AGP latency to 16 :nod:

The TicTac bios say something about altered also:


- CPU Disconnect Function Patch
- Side Band Addressing Enabled
- PCI Latency 128clck
- EXT P2P Discard Time 1ms
- LAN Latency 128clock
- SATA Latency 128clock

...and it is the LAN and SATA latency (what the hell is CPU Disconnect Function Patch?! This means that the CPU disconnect is disabled by default by other bioses - at least until the nForce2 drivers take over...???) that catch my eye.

What are the default values for them???

And of course the higher values means that the network and SATA ran faster/smoother. Im sure about it. However it maybe can criple the CPU speed a bit, and this is my concern.

Anyone can tell me more about it? :confused:

BTW, the fantastinc nForce2 tweaker by TicTac can't tweak these EXP /2P DIscard as well, as the LAN and SATA latency things... :(

Hellire bioses tested. Tests made on Lanparty B, made in China (ugh) with this standard settings: 200x13 1.800Vcore AXPM2600+ and 11-2-2-2-2-9-12-0-0-3-3-2-0-3-E-E-F-E settings for mem. All other settins was always and all the time same.

Tests consisting of memtest results (used latest 1.51 one - http://www.memtest.org ) and AIDA 32 ( http://download.computer.msn.de/syndication/msn/downloads/msn_download_10236956.html ) for the simple memory read/write test speed ;) (this one should be also more reliable and less fluctuating that for example popular Sisoft Sandra ;) and confirmed with TestCPU - a small czech guy proggy http://testcpu.webz.cz/ ;) )

Now what you all surely waiting for - the results :)

Hellfire rev.1
Memtest - 1454MB/sec
AIDA32 - read 3033 - 3042MB/sec - write 1222-1235MB/sec

Hellfire rev.2
Memtest - 1519MB/sec
AIDA32 - read 2902 - 2983MB/sec - write 1150-1185MB/sec

Hellfire rev.3
Memtest - 1519MB/sec
AIDA32 - read 3020 - 3046MB/sec - write 1223-1227MB/sec

Hellfire Turbo
Memtest - 1454MB/sec
AIDA32 - read 2664 - 2818MB/sec - write 1145-1212MB/sec

IMHO it clearly shows that the "Turbo" bios edition is the worsest (!) one, surprisingly. It fluctuated most with the results and it also show the worst performance.
The rev.2 show clear advantage in the memtest test over rev.1, however it failed to deliver the same performance increase in AIDA32 win test - in fact, it was slower that the rev.1 notably. Rev.3 got be best from all - good memtest score, like the rev.2, however it also show good score into the AIDA32 test, witch is the less fluctuating one and except the weird 1235MB/sec write peak of the rev.1, it beat all the other versions easily :)

Conclusion - SAE was right. Never dubt his experience again :rotf:

Were you referring to the post just prior? "All test done with 10x255, 2-2-2-11" Granted it is not extreme, but I wanted to be sure that as much as possible could be done as I did not know exactly to expect with some of the bios.

did you include the L12 mod in your bios? i know the HF3 bios has it built in, not sure how it effects that core though, i would try more CPU volts first, and 3.8 is way too much for NF2, i am more stable around 3.4-3.5 then i am at 3.6...

tictac, w/ the pencil vcore mod, do you still have to do the vsens mod?

i ask because i'm at 250x10=2500, and not even 2.0v vcore(setting) gets me into windows with 250x10.5=2625, and am debating doing the vcore/vsens mod w/ pots and smd grabbers(you know, the 2 wires you say to ignore in your pencil mod guide :D )
i know i can do 222x12=2664(at least, i could on my abit nf7-s)

also, as you can see in my sig, i'm getting 250x10, 11-2-2-2.0, now, i'm using whatever is the latest bios from dfi's website, would your or any other bios help me? does this board require the L12 mod? my abit needed it, i used a bios w/ the L12 mod and went from 222 to ~240 b4 i fried the board in a multimeter measuring incident leading me to get this dfi lp nf2 ultra-b

i havent tested the pencil Vcore mod higher than 2.0V... so i dont know if it need Vsense mod...
but anything lower than 2.0v dont need Vsense mod... just simple resistor pencil mod :)

Regarding L12 mod... i have no idea at all.... yeah NF7-S gain better stability with L12 mod...
Most LPB/Infinity can clock high enough even without L12 mod...
but.... i think SAE did L12 mod on his board tho... :hehe:

03-23-2005, 07:13 AM
SAE did but i dont think he knows if it gained him anything... i believe he was being redundant...

molester, i have had much better luck with the beta bios'es (1/21 specifically) and even better luck with HF3 (basically same as 1/21 with different romsip and L12 built in)

I also did well with tictac's bios, and vsense does nothing, you need to do the OCP mod, SAE posted pictures of it a few pages back, i would think that the OCP has to be done as even at 2.0vcore on stock board the vcore isnt very stable.

SAE
03-23-2005, 07:59 AM
Hmm. I do know for sure it gained me further stability. Once I was testing bioses with integrated L12, I could not get anything higher than 240 stable... could bench higher though. Stability came with "wire mods" - L12 and 1.775V default. :)

I'd recommend it.

what do you mean?

some values create more bandwidth, but limit clock, and some do the reverse, usually its better to go for more bandwidth then more clocks, but not always, to find the best value you can experiment yourself, as each system is different, i will do some experimentation of my own, but like i said, your results may vary.

Im kinda new here, sortof, long time reader - first time poster ;)

Anyway, i just killed my beautiful LPB, after accidentally pumping 3.5v through the NB :slapass: :explode2:

That should be a lesson, be careful when using a 100k pot with the VDD mod, watch how much you turn because you could potentially give loads of volts to the NB.

That board was amazing, it could do 265+ benchstable with 1.9v-2.0v on the NB, was china board as well, very few that can go that high.

i've tried 6-19 and 1-31... still gave a problem with the multiplier(only with 10.5)
infact when i flashed the BIOS with 1-31... i did load optimized default==>save and exit==>etc... when i turn on my computer i couldnt get into windows. so i tried to repair the windows..but i found another problem, my HDD like a brand new... had no partition at all... 38xxxMB... all my data has gone...dissapear...deleted...etc LOL

There's "Made in TW" written on its box? :) Great.

No, drv str and slew never helped me any... only made things worse.
So leave it at auto.

But the alpha timings are of some use - to be more exact: they're very important for stable and fast results! :fact:

I was using 2-0-3-3-1-0-2 the last time I had the board/cpu running.
You may also try 2-3-3-3-3-3-3 for more stability, or something like 2-2-3-3-2-2-3 for balanced stability/speed.

G'luck, bro :up:

I never needed that 4 at the end. :)

Cold boot problems can be avoided by wire modding the socket. You need to set your cpu to a higher default voltage (1.775V default is the one I did). Also do the l12 mod in hardware, means you're putting thin, u-shaped wires into the appropriate socket holes and put your cpu back in.

About those "hardmods".

I did vdimm, vcore, ocp, vdroop and vdd mods, wire mods and some lapping mods and cooling mods? Suffices? :D
P.S. Vsense is crap.

Talking about the alpha timings, I come accross this:

T(RC) - 9 (7 is better if the mem can handle, 12 if cant handle 9)
T(RFC) - 12 (15 if not stable)
T(DOE) - 1 (0 if you can get it stable)
T(RRD) - 1 (0 if you can get it stable)
T(W2P) - 3
T(W2R) - 3
T(REXT) - 1
T(R2P) - 1 (0 if you can get it stable)
T(R2W) - 3


Hmmm, using the old good Mushkin Special 2-2-2 BH6 at 2,9V and Vchipset auto + 200Mhz at

T(RC) - 7
T(RFC) - 12
T(DOE) - 0
T(RRD) - 0
T(W2P) - 3
T(W2R) - 3
T(REXT) - 2
T(R2P) - 0
T(R2W) - 3

...and any change of T(REXT) - to 1 bring BSOD :p
T(RC) - 7 I tried alone now, works no errors, but... I can't set into the bios 7...? So, will it is beneficial, after all? Anyway, is there any chance to get the T(REXT) down to 1 w/o increasing voltage by, for example, tweaking the Driving Strenght and Slew Rate? :rolleyes: :confused:

I even tried T(RC) - 6 and it did not crashed, but does it gain me any good? :rolleyes: :confused:

It would be interesting to see a comparison of Tweaker screens for each mb. Although the general settings are the same, the bios for the infinity has more available settings and may be different than previous. I had an Ultra35, very nice board. Also have a LPII, it is not so much different from Infinity. It should come around. Check out http://www.dfi-street.com/forum/index.php? Many things covered for dfi.

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.

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=badthingshappens&id=96&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.
http://ax2.old-cans.com/s.php?p=badthingshappens&v=v2&d=1&id=137&c=8

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:
The Hall of Shame - Badcaps Photo Montage
Teapo - http://www.badcaps.net/forum/showthread.php?t=424
List of Bad Cap Manufacturers
http://www.badcaps.net/forum/showthread.php?t=388
Teapo - http://www.teapo.com.tw

http://ax2.old-cans.com/badthingshappens/Teapo%20caps%20on%20Taiwan%20mobo.jpg
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

Informative post trodas. I can't remember the context that I was referring to the tweaker screens though. Actually I never got tweaker to work on my board when I had it. I think it was one of the first versions. My initial LPII was a Taiwan one, Rev.A. http://img303.imageshack.us/img303/9553/taiwan5ra.th.jpg (http://img303.imageshack.us/my.php?image=taiwan5ra.jpg) Back in the day it was one of the best. http://img303.imageshack.us/img303/2429/rankupdatec8ez.th.jpg (http://img303.imageshack.us/my.php?image=rankupdatec8ez.jpg) That was before I did the vdimm mod. I should have stopped there, but I went ahead later and did the additional ones for vcore. My soldering skills are not so good, and one of the ends eventually came loose causing a trace next to the socket to burn up. So it sits on the floor now. I got a second one after several purchases/returns. The China ones, one would not even boot in dual channel, I wanted nothing to do with. I did not know why they were different, although one was missing a couple caps that were on my first one. What I'm getting at, is the mosfets on my Taiwan are different from even what you show, and I just wanted to share that. The top row next to the chokes are AB326 while the bottom row has the CG339's. http://img72.imageshack.us/img72/3346/mofsetrows5az.th.jpg (http://img72.imageshack.us/my.php?image=mofsetrows5az.jpg)
I actually did get another LPII and use it for my daily computer.(no mods) I got it just before the release of the Ultra D's. It is a Rev.A but has the white out on it. However it is probably about as good as my first one. Mosfets on it are, top row:06N036LA/PD346, and lower row:09N03LA/LS410. I think the LPII boards are just awesome, the people who are happy with the ones they have should agree. My Taiwan has the VC320's at the vdimm, while the white out board has AC333 at the vdimm.

Hello!

This is my firs post here. I’m having trouble with my Ultra Infinity. Specs:
Ultra infinity 230 MHz @ 1.6V Taiwan
2x512 Twinmos SP 230 MHz @ 3.2V
Mobile barton 2530 MHz @ 1.825V
6800 GT 450/1190
Tagan 480W 3.3-28A, 5-48A, 12-28A

All the main mosfets are sinked and system is water cooled.

At these settings it can prime for 13h. And so is stable. But as soon as I increase Vcore to 1.85 or more it freezes. Prime or any other program never report errors. And the freezing is random usually when surfing or when I’m away from computer. It used to be able to take 1.85V. What do you think might be the problem? Caps? All the big caps around the cpu mosfets are brown. If you want I can post a picture of the setup…

coop - thanks :p: I now trying to insert as many caps on the board, as I can and some make the mobo unstable :eek: I managed to isolate 5 of them anyway, there for sure, unsure about two of them, however I think (as they aren't into the sensitive area) I should leave them alone ;) I still waiting to get my SMD clearing caps and stuff for testing of my resusciated mobo, tough :rolleyes:

About tweaker - well, it works well for me, however the auto-start / auto apply settings did not work on XP SP2 as well, as on XP SP1.0a. I looking for a fix, but unsucesfully yet... :rolleyes:

Sorry for you burned one, mate. But I also have rev. A one. However the mosfets is reported to have the same specs (the last digits are package and minor stuff only, at least from what I hear), so the only way to explain the better overclockability of taiwan ones are the caps. But then again, in the vital areas, they are same. And in the less interesting ones, the taiwan ones used totally cap Teapos, while China ones use better OST ones. At least according to the specs.
Frankly it means - worser specs = better overclock. Insane as it sounds. So, either the Teapos are't as bad and the OST specs is way off the reality, or there is something else. The cap issue will be determined sooner or later, as I hope soon I'm get the rest of the caps and I will replace everything with hi-quality Panasonic FM caps. So, if my overclock get worser, then it explain everything. But I believe my overclock will be far better, so... we have to wait for the damn caps to see... :(


The B - hello there. I bet it is the caps, but a nice picture of them is recommended. If something just freeze, it is not the Vcore, but rather the AGP/PCI power supply caps (the ones that failed on my mobo too)... Sinked mosfets did not do you any good, unless you have fan blowing air on them.
I has completely heatsinked mobo, run fanless, and problems are only worser. Removing heatinks helped there.
So, close-up (and write us the type of the caps - eg. what is on them printed) on caps 1 to 3 and next on caps 7 and 8 according to this my draw:

http://ax2.old-cans.com/DFI_LP_B_caps2.jpg

Are necessary. Be prepared to solder them off and replace them with better ones, tough ;)
It is a old mobo now, you know. Caps die.

Thank you for your answer.

Caps 1-3 are 6.3V 3300 uF and 8-7 are 16V 1500uF. 9, 34, 32, 31, 33, 30, 29 are Teapo. The thing is that 9 (which is Teapo) looks just like 1-8 only smaller. But on 1-8 there seems to be no manufacturer written.

So? What do you think is the problem? Which caps need to be replaced?

As you probably know the board is completely irreplaceable. So I don't want to mess with it unless there is a good chance of it working. I just want to prolong its life for a year (maybe less). Then I will get myself a proper system. If I kill it I’ll have to settle for Asrock 939 dual sata2 and a 3200+ Venice.

Sorry, getting burned with own reworks :p: Still waiting for the final caps, that SUXX ... :mad:

Cap's 1-8 are KZG ones, and only Chemi-con made KZG line of caps, so... ;) This is pretty easy to identify. Teapo are one of the worsest brands even in the bad caps brands - no wonder you having problems.
Cap 9 is used on the Taiwan mobos as Chemi-con as well, 1000uF 10V one. It is a cheap crappy OST on China mobos, witch may explain something about the overclocking ability, tough it has to do something with "just" SB and stuff, so I would never quess that it could be so important. Neverless I put there a 2200uF Panasonic FM and even bridge him from bottom 100nF ceramic cap for best filtering ever.
Such quality voltages my mobo never enjoyed even as new - ever :D :p: I expect it pay me my work back with nice and stable OC :D

So, you problem is? Mobo acting weird as soon, as you go to or over 1.850Vcore, IIRC? 1.850Vcore is the breaking point of the voltage regulator used. DFI moded it to go higher (2V and up with futher moding), however the mod seems to be failing for you. Since this is impossible, as no other that ceramic caps and resistors aren't used in this mod, I would like to think that you got the same issue as me and your caps finally giving up.

And yea, this board is not possible to replace today. Either you make it work, or you screw it up - you still can't use it well, as it is - or do you manage? ;)

And well, replacing caps (if you can solder well) can't kill a mobo - unless you use QUALITY ones. The Panasonic FM I used are the absolute low-end. If you go to anything lover, your board die. As simple, as it it. I once added 3 not-good-brand caps to the Vcore ones in parallel: http://ax2.old-cans.com/s.php?p=badthingshappens&id=3&c=8&d=1&v=v2
...and under 20min, the mobo is gone and I still haven't fixed it, even after replacing the mosfets... Now is time to replace the Vcore caps as well, but the chances aren't big, IMHO. It looks like something in the mobo PCB was possibly destroyed or something... :rolleyes:

Anyway, well, oscilloscope is on it's way, eh. We then SEE what I did to the voltages :)

And it is time for serious modification! Now - who need COM, LPT and SP/DIF ports, when use X-Fi?
http://www.slibe.com/images/4a249ffb-0125_jpg.jpg

http://www.slibe.com/images/4ff13f30-0126_jpg.jpg
It create more space for heatsink as well, as make the airflow better. So, why not?

I already get bored and removed the sound output ports as well, hehe. I did not even use them, since I using Audigy2zs and soon X-Fi Fatal1ty, so... And they does restrict the airflow, so for the sake of better cooling - off they go. And the board is still functional, LOL :D
Above this, I also removed every the remaining ten pieces of OST (one smaller Teapo between them, a 22uF for 25V one) 100uF caps between the PCI slots and one near the main power cord from PSU for 120uF 16V Panasonic FM ones. They are bit bigger and more bulky, tought I hate the idea of caps, marked as BAD CAPS and known to be prone for FAILING MISERABLY are on my mobo. Easpecially the cursed Teapo went off the mobo with big kick in the ****... :D

Now the only one caps that are originals there are the cursed 6 caps witch are going to be replaced as soon, as I get them and other that that - there is 12 10uF SMD caps, this one right to the bulky Panasonic:
http://ax2.old-cans.com/badthingshappens/Caps%20obsession.jpg
...and on it is writen 3t, 10, 16V.
Since they are near the AGP, around the sound output and some around the SB I did not think much about replacing them, but I have 10uF 16V ceramic caps, witch will do better job for sure - ceramics is always better that electrolyte ones, by their far lower ESL and ESR (means also more ripple current they could deliver...). But it is worth? Can they be failing?
Especially those near bellow the AGP port will be very hard to remove/replace...

Hi guys. Using the Mushkin Hi-Perv Lev.1 ones, 2x512MB with BH-6 chips.

Or so I was told on the website, not tried to take down the heatspreaders myself to take a peek...

I wonder if anyone can suggest a good drive strenght and slew rates for my two used dimm slots 1 and 3 ;)

For empty ones I use recommended 1/10 (strenght/slew), however with AUTO values for the used slots I maxed up at 249/250Mhz. Semi stable. Sometimes it pull trought the bench, sometimes it does not.
Tried 4/6 (IIRC the strenght/slew should be more agresive for 2x512MB sticks) but hexus PI fast benchmark ended up with horrible BSOD :lol: ;)

Suggestions wanted :p:

Got 1 Rules card.

DFI Lanparty NF2 Ultra-B

Some of the rules include:
1. TicTac 6/19 bios
2. Vcore Vmod
3. Vsens Vmod
4. All sinked up
5. Water cooling/ramsinks for vidcard


Now, if anyone wants to add some rules, let me know. I won't be doing the Vdimm Vmod, as I don't think I'll need more than 3.3v, never have to this point, and I can't solder, nor do I know anyone that can. The other Vmods are done with grabbers. I also have no plan to replace caps.

Thanx for your input,
John

Max Tractor - sorry, don't know. Never used SATA, hate it...


TWO questions for all :D


1) What is the APX O/C WR (World Record) clock on air?


2) Speaking about mods, how much resistance one should add there:

http://upl.silentwhisper.net/uplfolders/upload0/vddandvdimmmodds.jpg

To get +0.2 - +0.25V apart from what one set in bios?
I mean - how much give 0.1V or something, so I should just solder there a resistor and not a VR (Variable Resistor), as all I need is about 0.2V raise for extreme OC :p:

I have the same question as Trodas. I'm trying to stabilize 250FSB (10x) with my LanParty NFII Ultra B using Mushkin Redline XP4000 (2x512) UTT CH-5 in dual channel mode. At this time I'm using Hellfire 3EG Rev3.

I get as high as 236FSB and 240 is somewhat stable when I loosen the alphas. However, 250 still remains elusive even with loose memory and alpha timings.

At this point, I'm testing each Mushkin stick individually. I just want to see if either stick can run at 250FSB (10x) and pass SuperPI 32M.

For far, I've tested one stick (slot#1) and it passed. I'm testing the other stick and when I get a result I will post back.

With one stick I used a vdimm of 3.3, Vdd 1.8 and 11-2-2-2-2.0;13,15. I left the alphas and drive strength and slew rates on auto.

It seems to me that running in dual-channel with these memory sticks may simply require more than 3.3v. But if the other individual sticks passes SuperPI 32M, then I have to believe the northbridge memory controller simply can't deal with the load of two of sticks at 250FSB.

That's the theory at this point.

--Fernando

*Update* The second individual stick also completed SuperPI 32M. So, both sticks (individually) can do 250FSB (10x) with SuperPI 32M. This was done with each stick in slot#1 (closest to CPU). Now, I'm testing both sticks in slots 1&3. After I get a result, I will post back again.

*Update#2* Using dual-channel mode (slots1&3) SuperPI 32M failed in the first loop. This occurred even when I bumped up the vdd from 1.8 to 1.9. Vdimm was 3.3v. This appears to support the argument that not all northbridges are the same. It seems there are some variations because some LP-B users out there can do 10x250 with UTT CH-5 or BH-5/BH-6 just by 'burning in' the ram with command per clock enabled. I did try with cpc-off and it didn't make any difference. 250FSB (10x) in dual channel is not going to happen under these conditions.

Hi guys. Using the Mushkin Hi-Perv Lev.1 ones, 2x512MB with BH-6 chips.

I wonder if anyone can suggest a good drive strenght and slew rates for my two used dimm slots 1 and 3 ;)

Suggestions wanted :p:

I was told that when the drive strength and slew rate settings were on 'auto' they are 4-11. But I haven't been able to confirm that myself.

Have you tried loosening the alphas for 250FSB? I've had some success using the parameters in sig I found from the forums.

For example try these:

8-2-2-2-2.0;14,16;5,4,5,3,3,5,4,;e,e,f,e;4-11,4-11,4-11

You could substitute the empty ram slot with 1-10 as you suggested.

Also try this:

8-2-2-2-2.0;14,16;5,4,6,3,3,4,5;e,e,f,e,;4-11,4-11,4-11

Again you can substitute the empty ram slot with 1-10 if you like or you can simply leave all of them on 'auto.'

Report back after you tried this.

Thanks!

Dropping the FSB from 250 to 245 (10x) didn't make a difference with SuperPI 32M (2x512 dual-channel with CPC-ON). It still failed (first loop).

I dropped it down from 245 to 240 (10.5x) and currently testing SuperPI 32M again.

Will report back with results!

what kind of cooling do you have for your north bridge? i use a Vantec Iceberq, copper....

i also sinked the mosfets..while I could only stable 252fsb with water and radiator on a/c vent, it was still possible, using 1.8v chipset, 3.1v ram(corsair 2x256 bh5, dual-channel mode, cpc on, all timings in sig, and alphas/strengths at auto), and 1.950v vcore(252x10.5)

Sharptooth+ - you obviously need to concentrate on two issues - Vdimm area and Vdimm mosfets cooling AND north bridge cooling. I getting the idea that your mobo w/o modifications in the caps and cooling can't handle prime stable more that 236Mhz dual channel. Remember, 2x512 is bad for nF2. All records are done with 256MB sticks for this reason...
Futhermore for the CH-5 stick are might the drive / skew settings inapropriate, but I can't suggest anything in this area.

VulgarHandle - sounds good that you don't giving up, dude :D ;)

Actually, I have a Swiftech MCX159-A on the northbridge and my vdimm and mosfets all have Microcool heatsinks on them. So, it's not my cooling :nono:

2x512 can be bad for NFII boards but you would be surprised by some I know who can do it with cpc-on and 250FSB! :stick:

My particular board does not use the Teapo caps. So, I don't think I have to replace any of them. :clap:

Hey skinnie, nice work on your modding. Looks very good. I am using the same board and chip on this comp. No mods though. It is even an IQYHA 351 It is my "everyday comp" I included a screen. I have a large Thermalright copper cooler, the one before the heatpipes. Keeps temps cool. You should be able to clock higher if you want with your setup. With 2-256's you can get up there. You will need I think to change your vdimm up some and you have a large range of multipliers. My vagp is 1.6v and vdd is 1.7v I have to disable cpc due to 2-512mb rams. I had a modded one some time ago. This one is stock though like I mentioned. Solid board, one of the best.http://img464.imageshack.us/img464/7653/nf2ix0.jpg (http://imageshack.us)

Go by the darn caps on the board, there's a huge diff!, I'd otherwise go by the fets if I knew how they were configured and how to read them.
Also note that it's about equal with VTT that way, now it makes sense...
Also that's why mbm reads it way off, like it should apparently, when sensor is *0.016 (I dn if that calculation for the sensor is correct though).

Yeah I know they are a mess...
Anyways you should beable to figure out the vmod for mem from that info.
It's an easy peasy pencil mod.

They are VERY old notes though...
I'de probably have to re-compile a bios, I don't know what the last one I compile was all about so it would probably be best I just re-compile it if anyone wanted it.

Hi NEOAethyr and thank you.

Yes v dimm mod can help me because lot of mb with NF2 can overvolt dimm only to 2.8-2.9v. I must say, that i'm not fit at electricity.

Second thing is fsb limitations. In this review you can read that only with 3 mb they do 240 fsb.
I think one was DFi Infinity, second DFI Lanparty , third was AN7 ( even if this review is only with high AN7 fsb on the websites. Others reviews i saw max 225 fsb limitations )

http://www.hexus.net/content/item.php?item=681&page=12

Nevermind all of this mb are very rarely here.

Because only DFi i found is DFI nForce2 400-AL NF2. :confused:

What board do you have, the DFI nForce2 400-AL ?

I can tell you what the dfi lpa and what the lpb needs for a mem vmod.
Same goes for the inf.

You can go all the way up to about 0.02v under what your 5v rail is set at.
I've ran some samsung at that voltage before, just booting it though, didn't stress them at that voltage.

But the other boards, I don't think I could tell you just by looking.
Well I could probably make some good guesses but I'de need some high res close up shots of the mem controller chip and the parts around it.


Supposedly most of the nf2's clock well with a good bios.
Some are ami bios'es though like asus's vm board.

I don't have motherboard yet. I'm still looking for.

I have offer to buy DFI nForce2 400-AL NF2, but it is single channel and i saw only about 210 fsb max.

I find highest fsb with:

Abit NF7-S 2.0 rev. with mod. bios ( >250 fsb),
Msi K7N2 Delta2 Platinum with v11.3 bios (250fsb)

that's good, but vdimm mod for me needed :)

04-22-2011, 02:14 AM
If I remember right the abit nf7 s2 wasn't as good as the original.
The dfi al isn't that good at all...

The msi I'm not sure of.

I would go for either the abit, or the msi.


I have had, lemme think...
2x utt 512m sticks, centon pc4000 (got rid of).
1x utt 512m stick, centon oem stick.
2x corsair plat ch-5, dual sidded 256m sticks (I wish they weren't dual sided though).

What I run with on my lpb, when I have it running that is...
The 512m oem centon utt, and one of the 256m sticks of ch5.

The lpa I have I run with 2x512m of samsung uccc.

All of my mem gets to 240-250 with the normal bios voltage levels, I think I ran 3.2v on the lpb (3.1v setting).

The centon pc4000 I had, originally it got messed up and wouldn't pass s&m.
But clocked pass 266 on memtest easy.
After breaking them in one day, they were s&m stable but no longer high fsb stable passed 233 or so.
Could of been the board though, I had to replace alot of dead caps when I got it from London (it lasted a few days then went to shiz real fast, was kinda scary at the time).

Hi mate, yes i remember, was Lanparty for me :rofl:
(that mb was so good, sold and buy back after some time and again sold after some time).
Now still working with mobile cpu by one man. :yepp:

Im' trying resurrection the legend and guess no other mb than DFI Lanparty
( one from you) or Infinity ( had 2 of them- the second run to windows at 265fsb without mods ) can make the job well.
I wanna high fsb and need 3.3v for Bh5.



Ah, that was you^^ I barely remember much. But my modded board and the cpu were a gem combo. What happened to them?

I gotta up at least one more bios for the lpb, will doit soon.
The lpb is one heck of a powerhouse to say the least, for how old it is it still performs quite well cpc, video playback wise :).
I'm using mine as a tv deck at the moment until I can get the time to re-write the bios and install win7 emb on it.

Has a qfx4k, and slk-947u I think it was and a gig of winbond.

Sorry guys, I know I said I would make at least one more bios for this board before now and I haven't yet.
Things have been very hectic lately so I haven't been able to yet.

I just got ok'ed for disability, and got all the free loading crack head thieves out of my house (finally... :\ ).
I had worked on the src code for it a few times and it's compiling, and working on the board.
But the bios isn't fixed yet, I haven't figured out the reason for the prob just yet.

The prob with my last bios is the raid rom don't work on the lpb board.
It just skips over it.
I compiled another test bios the other day but haven't gotten around to testing it yet, I gotta re-setup my usb stick to boot into dos (impossible for me to do in win7, gotta use the lpb and win2k3 to do it lol).
But I "promise" I'll fix it up pretty soon.

One other thing I need to do is tune up the rom sip.
I had redid the loader for it so it's dynamic, baised on the fsb.
Much like the original code, but mine is a bit finer in detail, since unlike dfi, I know how to run it past 250mhz fsb and what it needs to do so ruffly...

Speaking of which, a long time ago, 2 years ago now I think, I had put in a special option in the bios to hand select the sip you wanted to use.
I had options like:
200, 225, 250...
Auto, test 1, test2, hellfire 3eg-r2, tictac, etc etc etc.
But in the end, what ended up happending is that I was using a scratch area of the cmos for the setting and on some boots it would totally screw up the value.
So I commented out the code for all of that stuff, I would love to get back into it though.
After which I made the timings in the sip somewhat generic for the lpa bios (I have them both sharing the same src file's, just diff make files), so I gotta tune it back up for both speed and stability.
I'm living alone in my own house though now, so I can open the windows in the middle of the winter (warm winter this year though), or crank the air on for testing of stuff like this.

I'm getting a bunch of money in back pay too, already did the calc for the fee's and so on (plus I'm sueing the hospital for my mom's death).
Now that I think about it, perhaps I should buy something to sub zero cool that mofo for some real testing.

Edit:
I didn't think of this...
Since dfi is out of the game these days, is it possible to sign an nda to get the src code for the bios on the lpb/lpa board's?
I may need to sign one for nvidia and amd as well, which doesn't matter to me I'de doit (and honer the agreement).
It would be very helpful so I can figure out some area of the cmos I could use for extra goodies int eh bios, I can add a HECK OF ALOT more timing options and such if I had that ability.
Or even just the ability to program the cmos chip it's self, it's 64k, way more then what's needed for cmos reloaded and the bios'es current working set, just that info alone, smbus info (I don't know how to smbus program yet at all), I would beable to do all I needed.
If someone can get ahold of me about this that would be awesome, totally serious.


Edit:
I have no idea what the date is, stupid windows and utc crap, gotta set the date form the bios..
Anyways last night I flashed over the 728 bios and the raid rom was working so it's not my board's caps or anything.
I did try to get it working by using a raid rom that I knew worked but that didn't work out either.
I'm not sure what the prob is is yet, still working on it, personal life is to much right now but I'll get that bios working again...

Hey neo, you might remember me from DFI/ DIY street. I am about to revive my LPB with 2G corsair and a Radeon 4570. Have you managed to get 1080p playback working using your setup? Oh and I'll flash to your latest bios of course. I gave away my LP-A sadly but I have a DFI NF3 SKT 754 around also that I'd like to rebuild. I love these old boards :D

I did make a nf3 bios at one time..

I don't have a good lpb bios right now.
I just got a usb stick back and my internet back working lol.
I'm gonna try to fix the lpb bios bugs I have on my end (src code probs, I went to far with it and screwed up the raid rom loading somehow).
I'll try to doit as soon as I can, but I can't promise it will be very soon.

1080p playback, just barely, I got it to play a little bit, but with subtitles it was a nogo.
720p was perfectly fine though (most rips within reasonable size are 720p, unless you want the best anime rips...).

My lpa board is still going, with the latest decent bios I made for that.
But unfortunately some of the cpu caps are bulging on it now.
It still has all it's stock caps on it, I bought it used too.
I have to re-cap it.

The lpb seems to be doing alright'ish.
All the caps I used on it were old used caps from other boards though.
That's probably what held me back on that board in fsb, the original board I had, I bought new I got to 283mhz fsb s&m/prime95/superpi 32m stable.
I so regret getting mad back in the day over the dfi nf4 pos, that day I smashed all my computer parts including the wr lpb board I had :(.

I'm thinking about sticking my lpb in the freezer so I can pop off that giant heatsink I put on the nb.
I won't beable to re-cap it or do any hard mods with that gigantic thing on there in the way lol.
