thanx man! but that's not what i wanted to hear :( here's the thing i just discovered, though... at 258x9 and 1.93vdd (1.9v BIOS) i pass SuperPi32M. but once i lower it to 1.82vdd (1.8v BIOS) it errors out right in the middle. i repeated it twice and got same pattern... so maybe it will get me higher if i mod it :) i'll do it tommorow maybe....Quote:

ok, maybe i should not be posting that here... but anyway, i'm kind of excited so i will :D
since i'm staying up late tonight i did vdd mod on my Infinity.... 1.90v BIOS gives me 2.09v with a multimeter. and guess what ???
...it booted up just fine @ 261x9 (before it would freeze during POST) and ripped through SuperPi16M like it was butter :banana: so it looks like giving the chipset more juice helps - at least my mainboard :) i'll keep pushing it, especially at higher multis...
so on,
It does not really help with high fsb at high multis...
So don't be too anxious ;)
/edit. I can use 2.2V with the mod plugged in, but it makes no difference at all.
hey SAE, do u have APIC and ACPI disabled? Im at 255x10 prime stable right now with both enabled, and I cant get 250x10.5 stable, so I was wondering whether u think I should try to disable them? think it would help? :rolleyes:
so what is yje secret then :) ? what do u think gives you such high FSB at even very high multis? can u tell me ? :)Quote:

Secret?! Hmm. In case there is something like that... my hardware did not reveal it to me ;) IMHO my ram is great, the board's decent too, the mods help a lot, my cpu's great, my cooling too :DQuote:

i 'm thinking that 25ish is the board's limit... coz i have 3 kits of 512MB BH-5 here to work with... all of them are doing 260x9 @ 3.65v but non of them will give me 260x10 stable enough in SuperPi32M... so i assume it MUST be the board... anything else i should try ?
thanx
yeah SAE tell us :D
I did:
VDimm
Vdd
Vcore
Vdroop
OCP
And the cap mod the newer boards already have (between the first two ram mosfets)
SB Vdd gains you nothing, at least it did not stabilize things for me with apic enabled. From LORD I know he even had to drop the alpha timings a bit to get a stable system.
So I'd suggest you all: don't do it, it's not worth the hassle...
And the better every mosfet and driver ic is cooled, the faster they can switch - increased stability is what we get ;) Don't forget to place some fans there to cool everything down more quickly.
That's it. :D
thanks for the info on the south vdd...can you explain the vdrop and OCp to me? like what i need to do and what they do for you?Quote:

OCP allows more current to get through to the CPU -> more current -> more power (but also thermal power should increase, and it's dangerous indeed)
Vdroop is a mod to avoid or minimize a droop in the vcore supply when the mosfets are switching (IMHO), it's stabilizing the vcore a bit.
we should just steals sae's LB.....
ja wohl :P
Thanks soo much! i really need that! i have been googling for a droop mod and havent came up with anything yet....the guys over at EOCF didnt even know it was possible!Quote:

thanks!
I used a 1k. I would say use a 2k or 5k.
as to OCP, its best to use fixed since it is very hard to fine tune 3xVR's and if they got bumped....
well, so i just did vcore mod... works just fine but unfortunately doesn't help me to use over 2.02v (multimeter). it seems that for some reason i can bench at up to 2.07v but running prime95 causes reboots after about 30sec... when i go back to 2.02v prime has no problems at all...
is there any sort ov OVP mod that will let me overcome this problem?
OCP mod
but isn't OCP mod different from OVP? i was thinking about it but i would really need to know for sure if that helps as this is far more invasive mod...
I havent seen an OVP mod for the lpb/infinity as far as I know... or one that works for that matter.
OCP is the issue usually.
i just keep coming with those posts, don't i ? but maybe some would find it usefull one day :)
so, i did "OCP-overcome" mod.... i didn't have any fixed resistors on hand so i used 5k ohm trimmers set at 3k ohm...
i had no reboot after Prime95 was started :banana: as a matter of fact i set 247x10.5=2600MHz which is Prime-stable @ 1.95v but this time i bumped vcore to 2.11v idle. while "Priming" it jumped to 2.14v and pretty much stays there :)
so far i have vdimm, vdd, vcore, vsense (disconnected atm) and ocp mods :)
i'm not sure if i really need vdroop and vsense, though...
greets,
should be good ;)
for those that need a confirmation that vsense mod might not be neccesary (as SAE mentioned) - check out the attachments...
stable 2.20v LOAD with no vsense mod and where this voltage takes my xp-m 2500+ :banana: "Priming" as we speak...
oddly enough i could bench at this speed with only 2.07v before but never Prime95 stable...
Hi,
last week I bought the ultra infinity board. The change to a NF7 is very big. With the same system I reached 240fsb on the NF7 and now 265fsb. My question is now how can I reach more?
My rig:
Ultra Infinity Hellfire Rev3 bios, Vdd-Vcore-Vmem modded, Vdd@2,2V @-31°C
Vmem@3,7 with bh-5sticks 2x256 mushkin black levelII@ 11-2-2-2
R9800pro@XT 520/410 @-31°C
I found that for me the best alpha settings are AUTO. Everithing other is not so stable. I can run Memtest with 270fsb test#5 without problems @2,5,3,3,11 with windows is crashing. It doesnt matter which timings have the ram windows isnt stable even with lowest timings. So is the NB limiting me or the ram?? Or is it the CPU XP-m mobile2500+ on air? :mad:
thx
Yes, you can use a fixed resistor as well. I am also doing so :) I use a 4.75k metal film resistor.Quote:

BUT!!! : You are also decreasing the total vcore voltage doing that. So you'll have to compensate this decrease increasing the vcore through your vcore mod. :D
OCPmod like fixed resistors as STEvil said :) It's safer. (I prefer SMD resistors)
@diamonddog
Hmm. There are many possible causes for this behaviour of your system.
1. APIC
2. instabilities at certain voltage regulation units
3. some kinda over current protection
4. NB quality as well
5. SB
6. noise in the pcb
7. electrostatic/magnetic fields
... and so on
I also cannot figure out everything what's wrong here with my system ;)
I'd like to have 270fsb as well, but I don't wanna try anymore as from 260MHz on with max timings the NB/SB start to freak out... Socket A cannot run stable above that. Sound quits while gaming and so on. Occasional instabilities appear...
So no chance to get a stable 265 with evry device working correctly and sound or lan not dropping.
@bachus
Great job there, pal :thumbsup:
I think the parts causing the instabilities are the nb, sb, and that little square chip just under the ram slots that gets so darn hot..
If my board was still working today i'd pelt both chips and put a huge chunk of copper on that square chip just to see what happens :D
thx SAE
the APIC is off. All Mosfets are cooled with heatsinks so far. The SB is not very warm. I can try to cool it with a fan. For all the other things I can nothing for. So I'm on the end of the board I think. What about the CPU? Could it be the CPU? Some CPU's don't like high fsb's or?
Is there a decent guide to the cap mods anywhere? something better than the picture at the begining of this thread?
Yeah. It could also be the cpu. I had some that could not clock as high as my best ones, but there 've been always only 3-5MHz of a difference.Quote:

1.9vdd is too high for 250x9
I think is not too high...if it is, how high can we expect with vdd 1,9?...Quote:

gonna try with 1.7-1.8vdd then hehe
Why should 1.9V be too high?!
Hmm. :idea: Do you think all the boards/NBs act the same?! No way....
My board always loved the 1.9V setting, in case I set it lower it would not be stable... That's why I did the vdd mod. But the board I had before did not really like high vdds, it only wanted to get 1.6-1.7V, anything higher was unstable. So go figure... :D
The only nF2 board i've had that responded to more vdd was my old Epox 8rda+... the a7n8x's might too, but they are pos's so i'm not gonna bother with 'em.. ;)
That said, some do work better with higher vdd for some people, and i'm not sure why... it really is odd.
Maybe I should get an nf7 to play with.
can someone show me where i need to measure with a multimeter to see my vcore?
thanks
Scroll up and read again - don't forget to have a look at the pics this time!Quote:

hello , I seek Vmod Vio/vdimm on the NF2 Lan party rev B, somebody would have this vmod? thank you
the vdimm is on the 5v , will be necessary that I buy 100k ....
oh hehe sorry about that....is that the only place i can measure it though? cause mine is all filled with silicone and has heatsinks on them because i have it condensation proofed.....Quote:

The software reading ain't correct - imagine the cheapa$$ parts used for that (iirc uwackme once said that's like 2cents for the reading chip and 4cents for the DAC/ADC ;) )
what does a choke do anyways?
when i shutdown the rig, i didnt set the voltages down in the bios....now i did some vmods so should i do a cmos erase before i power up so i dont put too much voltage through something?
is it okay to do all vmods all at once or should i do one at a time so i can tell if something went wrong and pin point it?
let me remind you im also putting sub zero cooling on it all in one tear down....
thanks
i would do one at a time, thats what i did, for the same reason you mentioned :)
solder, test, increase voltage, test, next mod :D
My "new" mobo, 1. run: 275FSB, Vdimm, Vsb, L12 mods.
i thought the L12 didnt even do anything on a 2500mQuote:

L12 on DFI ? HUH ?
I never regretted doing the L12 mod...
I only know, I once took it out cause OSKAR wanted to test if we still need the L12... and that was horrible. Nothing was stable as before... I had to lower my fsb 20MHz to get a semistable bench!
damn....273 on LP-B....
the hell of Nb cooling you must got there...
yea boblemagnifique that is a really nice oc. what mods have u done to the board? what bios are u using?
Hello
First of all, it is a lan party rev A, seen on the pcb, but it assembles well level fsb, level vmod, there is that the MOD Vdimm (200k) and in full aircooling (120m on the south, 80mm on North and mofset and Slk 800 on Cpu)
The BH5 is between 3.75v and 3.92v but does not change large thing
(Timmings 2/2/2/2/11/9/12/E/E/F/E)
The bios is LanParty 8KA Rev.2 http://hellfire.enclavenet.com/N24LD619-8KA-REV2.zip
倒
到底这块板好不好呀
should i get a lanparty A or B?
There is a marking of rev A on the pcb of the DFI Lanparty Ultra B (NF2U400).... but it only tells ya the revision of the pcb indeed, but the board's still a Lanparty B (B does not mean it's revision B - it's a COMPLETELY different board from Lanparty A -> layout, SATA vs. IDE RAID, ... )
SAE- wuts up man :)
was just wondering what kinda scores ur getting with your current setup (new x800). im guessing around 27-28k??
man I wanna see u get an A64 mobo and tweak the shizzle out of it, like you have done with the LP-B. :)
no doubt in my mind... SAE = nf2 king :worship: :up:
peace out man
FH

I am gonna get me a 939 sytsem in the beginning of 05. Hope it's affordable! (NF4+PCI-Xpress vid card+cpu should be a lot of bucks)
Thanks for your compliments :D
later, SAE :cool:
lol well I figured since u got 25.8k with your 9800, the x800 would get around 2k more. you underestimate yourself! ;) :p:Quote:

That's the problem....
The newer drivers suck bad on 3dm01 IMO.
ok im upping my nb cooling now (threw a 60mm on the stock nb) im making some ramsinks (gah this sucks spend an hour and im not done with 1st 4...need jigsaw or a var speed dremel) tommorow im getting the pots and i have an old video card in the freezer soon to have its passive sink pulled for mosfet cooling...
btw i had this thing running 255*10.5 prime stable stock on air, 260x10.5 almost prime stable, and now your saying 10.5 wasnt that stable... hehe... im getting exited lol, but maybe these ramsinks will be easier to just buy for $20 then spend 20 hours making them lol, im going to have to use two different hsf's by the time im done. (edit - i want ramsinks because this bh5 did 260 3.3v memtest stable before i pulled the spreaders, not even close without them, so i put them back on and still im not stable, hoping that sinks will fix this hehe
Hey Guys, hey SAE (originally Magedburg? My Hometown is Bernburg ;) )
Well, i might have a problem with overclocking my CPU via the Lanparty B...
My Hardware:
Lanparty B / Hellfire Rev3
2x 256 Corsair XMS Rev 1.1 Dual (Slot 1 and 3)
AMD XP-M 2600+
OK, the first i did was to set my timings vor the Ram on 2-2-2-11.
I increased the FSB up to 245 with multi on 9.5
VDimm is 3.3V and Chipset is running on 1.9V. VCore is still on auto...
So, the Problem for me... with this settings its impossible to set the multi to 10... even if i increase the Vcore...
The PC is not starting (blackscreen) or it starts and just before loading WinXP Pro SP2 it's restarting again...and so on.
Well, i'm a bit dissapointed of 2330 MHZ :(
I would be pleased for some hints...
I'm new in this field but hey... at one point i have to start a new hobby!? :D
Thx a lot!
Hi man :DQuote:

According to your problem, I must admit, it could be caused by many things.
1st What cooling are ya using??
2nd Try to do the L12 mods... I can supply you with a pic when I am at home.
3rd try to use the multiplier 11x. then start at 210 and work your way up. :) (I hope your cooling 's great ;))
4th check your die contact, reapply thermal paste and ensure you only put on a veryvery thin layer.
5th Oh, and the main thing I consider a problem, is you set the vcore to auto... not quite a good move! It means the cpu only gets supplied with 1.45V Vcore, so try to set that manually to 1.75V (don't worry, even with aircooling you can use that). Now try again! :D
Good luck, and report back your results please. :thumbsup:
P.S. Welcome to the sickness, pal :D :toast:
Salut!
Thx for the quick reply!
My origin is BBG, but working in Potsdam right now :D
Ok, the cooling:
Watercooled, but maybe not so good (about 50 degree without doing anything)
L12 mod: ??? :rolleyes: :D
3rd: i will check this!
4th: i will check this also. i think my waterblock is crap (aquarius 3)
and 5th: the vcore on auto is on 1.55V... and if i increase it seems not to be really stable (1.7 if i set 1.75 for example)
I look foreward when i'm at home!
Many Thx!
Hmm, Aquarius is a cheapa$$ kit, huh? :DQuote:

Drop me a pm about it. :)
The Vcore thingy is weird, there has to be a serious problem. Either cpu contact is bad, or cooling's insufficient. (I don't only refer to your cpu cooling, but also to your mosfet cooling and so on...)
Greetz, Stefan
OK!
I'll look for the contact of the CPU and check the heatsink and afterwards look for Vcorestability...
The L12 mod... i found this big thread here, thx :)
I'll come back to your "PM offer" (plz in german :D :D )
cya!
Marcel
Hi!
Ok, i did the L12 Mod. Set Multi to 11 and increased the FSB up to 215. More is not possible with Multi on 11. On the other hand, L12 helped to increase FSB from 245 up to 253 with Multi on 9.5...
Increasing the VCore is also not possible. On Auto it's running on 1.53-1.55 and if i increase to 1.65 for example i have around 1.61... :confused:
Looks like a hell of work to be done :D
Marcel
im using the hellfire rev3 bios so doesnt that mean i dont need to do the L12 mod?
Doing the L12 mods in hardware always gets you some better results IMO ;)
So there's not only the romsip tables modified, but also the cpu.
hrmmm maybe ill try that out..
*goes to look for L12 thread*
50c is way too hot! Heck, i'm running silent air at 2400mhz 1.75v right now and load at 55c with ~28c ambient..
What power supply are you using?
Hi,Quote:

Mhm, i will check this when i'm at home...
Another weird thing is the liquid of the watercooling system. It's getting fewer and fewer, but without leaking somewhere. At least i could nothing detect...
ok so whats the best way to unsolder these resistor for the ocp mod, im not new to vmods but ive never had to remove things before...
and a 3k resitor would be ok for the vdroop right? i already have a bunch of 3k's for the ocp mod so as long as i do the vcore mod as well i wont have problem correct?
and also, where tthe heck can i get trimmers >10k locally?? radioshack doesnt have any over 10k and i dont have a CC at the moment...
oh and also, i saw a few pages back people were discussing effectivness of more vdd, going from 1.7 on vdd to 1.9 got me from 250 to 257 and now my ram is limiting hence me modding my board heh...
the stock nb cooler on my mobo when i took it off it was only touchingthe NB on two corners (ahh!) so i lapped it to crap and i put a 60mm fan on it is that enough cooling to experiment with raising VDD or should i just forget about that mod?
thanks everyone :toast:
@Esox (Hecht :D !?)
Weird thing with your cooling fluid!!! :confused: Dunno where it could go...
@Revv23
I take two solder irons with a very fine tip heating up both ends of the smd at the same time, this way you don't damage anything. Soldering the new one there is the same procedure, but often it IS harder to do ;)
vdroop you can compensate with the vcore mod, that's true. :D
Vdd is recommendable by me, but that's me ;) I use up to 2.2V, and it got me more stability.
thanks SAE, i have an old P3 mobo to try that out on, just need to get anoter soldering iron and practice a while.
now all i need to do is find a place to buy VR's locally...
NP. :)
VRs should be available in several variants... from 10ohm up to 100Mohm or so... I don't get it why you cannot get a hold of them :confused:
Try to get multiturn cermet pots, 25 turns should be fine.
most i can get that i know of is radio shack which maxes out at 15 turns and 10k... :(
im looking in phone book now for locall shop though so im praying
Yeah, that's what i did before! Wanna go fishing...? :D :DQuote:

@ Revv23
I hold thumbs for ya.
@ Esox
I like fishing, but over the last years I have not been fishing anymore :(
@Stealth
Could be your vdd, but not very likely. Maybe your ram ics are heating up to intensely.
Try swapping ram banks too. But a vdd mod may help though.
@ SAE
I also stopped it last year... :rolleyes:
Yeah. Too bad, but sometimes I miss it. For me it's already longer than one year.Quote:

It also depends on your cpu. If it's not capable, it won't get more capable with lower temps in most cases. Older cpus just cannot clock as high, many newer ones also cannot. So the die quality is an important factor, too.Quote:
