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

[VulgarHandle]

well, wanted to give a sorta update...

friend who has exact setup i have/had...

DFI LanParty nF2 Ultra-B, XP-M 2500+ 0343 MPMW(both his, not mine, we ordered cpu's at same time, got same stepping) on Jinu117 VapoLi

right now we're stuck at around 2.8 full stable, little above actually..just haven't had the time to invest for a good oc session

his board dosn't seem to like alot of settings i could get, in fact, my best 1m pi time is still better than his when i did mine on water at a lower clock, but higher fsb...

but we've yet to change his bios...and hopefully he'll let me through in the vcore and vsense mods...

we are able to hit 246 on his OCZ platinum rev.2's(2x512 TCCD) at 11-2-2-2-2.0 with 2.8v, which is nice

pics and such later

also, i'm still hunting for a new DFI LanParty nF2 Ultra-B for myself...

[punisher69]

this is still my main board today. look at my sig

that is ing insane..ordinary tccd in nf2 run that speed @ 2.5-2-2-2-5-2t :S

[VulgarHandle]

that is ing insane..ordinary tccd in nf2 run that speed @ 2.5-2-2-2-5-2t :S

his runs 1T (cpc on) and bandwidth is better with 11, not 5, on nf2..

we haven't done much since, haven't had time, and i'm pissed he won't let me throw on the vcore/vsense mods....(they're ready to go, just gotta be clipped on)

for myself, i'm about to settle on a nf7-s 2.0....just can't seem to find an ultra-b

[skinnie]

I run @8 I think it gives better bandwidth

[WeStSiDePLaYa]

aaah, what a blast from the past.

my first oc'ing board was the nf2 infinity. paired with a 2600+ mobile, 2x512mb mushkin BH-5 and a 5950U.

those were the good times, no need for 1000$ chips or quad sli, or 500$ psu's to be the best.

[skinnie]

ppl any of u gurus of dfi lpb know wich was the best bios for old bh5 stuff?modded or original...I'm now using oskar_wu 12.18 for my lil BH5

[skinnie]

ppl now that I find wich bios works..and alphas can anyone give me a page how to do the pencil mod to give more vdim?my problem is really vdim

[skinnie]

Ppl I now have done the vdimm mod that was on techpowerup but I can't pass 233 barrier..233 17h primestable with this alphas:



here's a pic of the board


but @234 3.4/.5 or even .6v it gives bsod in windows..

Tried "your" alphas and it is a lil more stable but after a while..bsod..

I have agp@67mhz,68mhz the 9800 will brake in memtest (I think it is the 9800pro,because I can play music without problems)
vagp - 1.6
vdimm - auto
vdd - 1.8 (that was what I needed to do 250 with the TCCD)
tried changing the timings to 2-2-3-11 or 2-3-2-11 but it is even worse...
drives and slew rates 5/10 1/10 5/10 (memory in 1st and 3rd channel)

any suggestion?

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.[IMG][/IMG]
[IMG][/IMG]

[skinnie]

my system is now@2560mhz I think,I had 2x512 tccd@252 but had to sell them..and now my only problem is really clocking up the mems...

[skinnie]

is anyone still clocking these beasts?
New bios mod's from NEO

Here

This guy is awesome,in about 4hours I tested 3 or 4 versions of the smae bios for nf2..and it has bios for nf3/nf4..I think he figured out that somehow nf2 and nf4 bios are very identical.see the whole post..it deserves..

[ex.treme]

Hi from return.

I found XP-M with old components and remember to wonderful AMD days. Also found old BH-5 2x256mb Twinmos .
Only problem is find mobo.

DFi Lanpary or Infinity is hard to find at used staff.

[SAE]

Search forum sales sections and ebay frequently. My old equipment went to Prague in 2004, btw.

[ex.treme]

Hi mate, yes i remember, was Lanparty for me
(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.

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.

In my locations are few good mb for oc, lot of A7n8x, some Epox, no ABit or DFI :-(

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.

[ex.treme]

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.

[NEOAethyr]

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.

[ex.treme]

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

[NEOAethyr]

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

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

Hello again

I still got 2xDfi boards and some bh5 sticks left.

My brother is using the Dfi Nf2 board...the same board that i did use long time ago...My mom and dad using the Dfi venus board. I´m are most of the time working now(2 jobs), and instead of overclocking i building bike engines with bigger pistongs(bigbore and more) and geting out more hp on the back wheel.

Wow, mate. Kind of a change, I must admit^^
