I did some testing with the sticks in a single config... and they are supposed to run 275 on A64 easily ;) (3.4-3.5V)Quote:

how did you made vdimm mod on dfi NF2 ULTRA INFINITY ?
how does it rail after mod ? from 2.9 to 3.6 ?
The common way... Infinity's and LP B's vdimm mod is exactly the same.Quote:

Hmm. What do you wanna know about the voltages??? I set the voltage to max in bios (3.3V) and go from there. 3.56V! More is too much for my poor old LP B... it cannot hold the voltage steadily and droops too much. That's what's causing instabilities. And I got the feeling it's already a problem with my current voltage.
Well, if I'm allowed, I put all the DFI Lanparty Ultra B on my sign... of course, all credits go to the owners of the posts I took them from (can't remember who posted them :eek: )
instead of sodlering new smd's for the ocp, could you just draw on them with a pencil like the 9800xt vmods?
No. Don't do that. You want to increase resistance, not to lower it. If you lower the resistance there, it would effect the current negatively thus allowing less current to get through the mosfets to the cpu.Quote:

hey guys, i gotta quick question here....
have u ever seen benchmark-stable FSB of higher than 252 with multis 9.5/10/10.5 ???
the reason i ask is that my so far max stable ( superpi16M-32M, PIFast, 3DMark01 and PCMark04 ) OC would be 259x9 11-2-2 cas2. i can get to Windows at 259FSB with above mentioned multis but Sandra locks and none of the benchmarks are possible to complete.
also i can do 251x11, but i can't do 251x10.5... is there any limitation as there was with NF7-S that Tictac fixed with a BIOS revision?
Hmm... I am not sure as I always use multipliers higher than 11 ;)Quote:

I may try 270x10.5 today ;)
thanx SAE,
i wish i could use anything higher that 250 @ multi x11 :p
well, maybe soon something is gonna change in that direction ;)
anyway, at the moment i can pull of set of benches @ 260x9 :thumbsup: but my goal is to get closer to you as far as FSB goes ( at least for now ;) )
Hmm. Are you using the abit of dfi for these settings/benches??Quote:

I'll report back later, commander ;)
whoa! i guess i need to look a little bit deeper then...
to be honest with you i just started playing with all those Alpha timmings, Driving Strength, etc and i see some improvements as far as stability goes...
tommorow i'll get to play with 10.5 one more time... if i somehow get 260x10.5 to work then i will be extremely happy camper :)
thanx for your help, master :)

(slack alpha timings though(alphas for gaming), 11-2-2-2-2.0)
edit. And see the 16M at 11x multiplier :D

i heard that some mod has to be done ?
something about
DFI LP/Infinity high Vcore fluctuation problem
how can it be detected ?
point me to
Vcore,V-DIMM,V-OPC,V-Drop,V-Sense and VDD Mods
what's OPC / DROP and Sense ? LOL
Please read some pages back in this thread... I attached a pic/description of all the important mods to my post.Quote:

VDroop is a mod to smoothen out droops in the current/voltage graph (a dip in the curve) and allows a higher stable vcore with less fluctuation.
Sense does not really make any SENSE :lol: Don't do it- it's useless here.
SAE 15 pages to read...ouch
ich habbe keine zeit :P
/me spank my bad deutche uber alless :D
hey magdeburg seems familiar....handball team ? ja wohl
remember game against celje from slovenija LOL
Have everything you need on my signature :DQuote:

hello dudes i really need a good advise on this one:
hell yes, i'm a complete amateur when it comes to soldering - but i needed the vdimm mod because i got some bh-6 sticks that won't even do 240 11-2-2-2-2.0-9-12 DC stable at 3,3V (3,28V shown in BIOS, 3,36V measured on the board). so i wanted to go for at least 3.5 or 3,6V to see what these poor sticks can do :D
while trying to do the vdimm mod, i accidently unsoldered that small resistor that u have to solder on. yeah i guess i was touching that resistor just a notch too long and then it glued on my soldering iron. oh sh1t!! :D
now i measured the resistor and it says 123k ohms (with some solder left on it)
now my question do you folks think i can rescue the board (and how ??? :slobber: )
what would happen if i tried to run the board without the resistor (probably not much as it wont boot at all i guess) ??
i will ask my dad if he can fix the whole thing for me but its not easy to solder that tiny resistor back in its place you need a very calm hand :rolleyes: so he might not be able to... anyways i hope you can support me with some advice thank you all in advance :)
Hi Jens.
I often rescued boards like yours... you can either solder wires to the solderpads and place a 200k/150k multiturn cermet pot (25 turns from conrad electonics) inbetween. Or you just solder the SMD back onto the board.
I often worked with SMDs on my boards and the first slot a athlons (cache divider ;) ) - it does not have the perfect machined looks, but works and looks okay :D
... my testing continues...
so after playing around with my mobo i might be getting somewhere...
vdd maxed @ 1.90v (1.93v at multimeter), vdimm @ 3.55v... this is max what i can get before either system don't post or sandra hard-locks on me big time: 260x9 or 255x10 or 252x10.5. upping vdimm makes no difference at all.
my question is: did modded vdd (above 2.00v) make any difference to those of you with high (i mean HIGH :) ) FSB speeds, especially at higher multis? i'm about to do it anyway but just wanted to get hand-on experience from, eg. SAE or Electron or others...
thanx guys,
Between stock and 1.95v got me nothing. 263fsb @ 3.6v or so was about all my board could do..
