Ok, i get the mod, so there's no way around cutting pin 19 ?

yes if u have a v 1.2 abit added a resistor in the trace your breaking when u lift the pin i have a ver 1.0 so i lifted the pin was kinda easy i lifted pins 19 and 20 cuz they are so small just stuck 20 back down made sure there was no contact between the pins with my muti meter sodered the 10 ohm resistor to the mosfit and pin 19 fan plug to ground and pin 19 pluged a 100 ohm resistor into the fan plug and bam 3.12 vdimm
Wait a minute....
Oppainter, what exactly you did here,

The latest Nf7 Bandwidth. Did this at 11.5 x 250, 1 stick Kingston at 6-2-2-2 timings, 3.12V, VDD at 2.12V.
Can't get past 238 on Dimm3 with this board so high dual channel is shot. I wonder if other people are have problems with Dimm3.

You don't need to cut the pin, there is a small resister in the trace you can just take off, this gives you a cut in the trace. Then do the 10 ohm and 100 ohm VR combo.
I'm thinking now that all you really need to do is solder a 100 ohm VR to the Pin side of the mobos resister without taking it off the board.

this is what i got useing dimms 2and3 insync 1.95vcore 3.1 vdimm
1.95 vdd oh the timmings were 2.5 2 2 7 i cant boot at 250 probably need more vdd what is your thoughts oppainter
I'd say go for 2.1 VDD, I've been useing it a while with no problems YET:D
OPP
Not Yet! hehe
Good going Opp ! that stinks about your dimm 3 not up to speed would like to see some DC runs from you, you're probably tired of being asked this but are your running a tec on the Nb ?
OPPAINTER,
"I'm thinking now that all you really need to do is solder a 10Ohm VR to the Pin side off the mobos resister without taking it off the board."
Actually that's what i thought you did in the pic. So, just solder a 10Ohm VR to one end of that resistor on the mobo, right ? Is that the one closest to the WB...... chip ?
"Can't get past 238 on Dimm3 with this board so high dual channel is shot. I wonder if other people are have problems with Dimm3."
Right now i'm @ 240fsb and the 2 x 256mb samsung pc3200 @ 2.9v boots @ 480 DDR but not stable to boot in windows.
Would a 10k pot @ 10ohm work cause i don't have anything 10ohm right now ?
i have noticed a problem with the vdimm volts when at 3.1 it drops big time to 3.06 up to 3.15 the only thing that comes to mind is capaciters not handling the volts correctly 3.00 is rock solid or is this a board to board problem.
First off, it would be a 100 ohm VR not 10 ohm, secondlly I wouln't use a fixed resister unless I knew the mod worked already.Quote:

Oh yeah...
lol
No..... a 5.6k is 5,600 Ohm... it's a 56 OHM And it did give me exactly 3.2 vMem...Quote:

That's 5.6k ohm ?
About the vmem on the NF7-S, what exactly has to be done ?
As far as what has to be done.. OPP detailed it nicely earlier in the thread.

RoydRage,
Sorry i thought it was a typo, i've just started reading on this mod minutes ago.
Ok, i looked @ the resistor on the mobo closest to the WB..... chip & saw the trace. I took a 10k VR to ~100 ohm cause i don't have anything else & i'm gonna go ahead and do it, i'll let you guys know.
Thanx to everyone for the info, much appreciated.
Well, the mod does indeed work.
Took the voltage up to ~3.4v, anymore than that and the board wouldn't boot, i guess that's the max.
I was able to run Sandra @ 233fsb, 2x256mb samsung pc3200 cl3 @ 466DDR @ 3.3v & got this bandwidth,
3508/3256 - mem timmings @ SPD, 12, 6, 6, cas 3.0
Though windows booted the windows registry blew up when @ 240fsb/480DDR ram.......bummer.
hey guys quick question....i am looking at a nf7-s today at a local retailer..now does the nf7 have two different nothbridges like the 8rda coded A2 or A3 because all i can find is a A2 nothbridge.
sorry if its poster somewere else but i am on someone elses pc and all i can see is nothing of this page she has a old pc...this kills me 480x600 daxxx old stuff....any way if any of you know off hand i would like to know before i go and purchase it.
well i see there is a a3 nothbridge so i will keep on looking i guess ,
thanks guys
Most (not all) of the v1.2's have the A3.
Congratz OPP :D 250Mhz FSB is "GOD LIKE" :D
Till what FSB gan u go Dual Channel MAX Stable ??
hey guys where can i buy a nf7-s online that has the a3 northbridge.i mean who has gotten one and from where.because i am ordering one this weekend and i want to get the best stepping i can.
thanks:D
I've ordered 2 from excaliber and both have been A3 NB. Both were on seperate orders. I don't think you can request A3, but chances might be good with these guys.
2 NF7-S's and a NF7-M all had rev A3.
I don't know if it matters.

This NF7 1.2 of mine is stuck on stupid for dual channel. The Dimm 3 can only do 218 with agressive timings so Dual channel is shot. I guess I try a different mobo.
Running 2 sticks in dimm 1 and 2 right now at 242 with 3-2-2-Cas2 timings, still, the dual channel is what give the mobo performance.

I've had 2 from Azzo both with the A3 NB.
