all i have here is a 5.6k fixed....will that work out good? whats the advantage of higer or lower and how low is too low?Quote:

My board does not like lower voltage anymore :( I could run 263 at 3.34V before with other LP B.
@stealth
5.6k is fine. Smaller values result in a smaller drop, but cause the total vcore to droop more. You had to compensate it more through higher vcore at the pin7 vcore mod.
Merry Xmas everyone :)
From me, too :D
And burn the candles, not your rig ;) :lol:
Hi .
My config and sets:
Bios original DFI 6/19
XPM 2600 + at 2500mhz over 1,8V, this mobo brutally undervolted, set up 1,8 and in MBM is low value from Prime 95 1,68V :eek:
vcore 1,775v
vdimm 3,3v 11-2-2-2 -auto - cpc off, on is not stable 5-10 min fail Prime
vdd 1,9v
vagp auto
agp mhz auto
And now see the problem :
250x9,5-2375mhz - @1,775v, 1,9 , 3,3v - 112222 13-15-auto cpc off,Prime after 2h blueescreen fail - STOP 0x00000050 PAGE_FAULT_IN_NONPAGED_AREA
(AGP 66 fsb, AGP - defv,Agp latency 128, Apic disabled.
250x9,5-2375mhz - @1,775v, 1,9 , 3,3v - 112222 13-15-auto cpc off,Prime 51 min fail (AGP 66 fsb, AGP - defv,Agp latency 128, Apic enabled.
At the support MS is this bluescreen display drivers or nvidia drivers?
thx for help.
Try to set your AGP clock to 75MHz, AGP voltage to 1.7V, set TRC to 12 and TRFC to 16. Try to use ram sticks in a different order, and try to put the sticks in slots 1+3 instead of 2+3 or the other way around.
Another important thing not being evident for me is: what size of ram stick do ya own, what brand and what chips!?
I try else install this Morpheus extreme video drivers.
Ram 2x256 mb Twinmos Bh-5 with copper heatsink slot 2+3
Now i test in Prime 95 245x10 the same setting but cpc on, and bluescreen after 45 min. :(
try slots 1 + 3, vdd 1.7, vagp 1.7, and vcore at 1.8
sounds like maybe its heat?
on my LPD, i havnt put sinks on any clockgens or mosfets and the vdd mosfet is 60c and th lil black chip at the end of the agp slot is 60c, if i cool them woul i get better stability? im waiting for my thermal tape in the mail and i dont want to use thermal epoxy because it doesnt come off.
i also got a temp monitor, where do i put it to monitor my cpu temps? thanks
EDIT:listen to this. i started running 245x11=2700 and now i can literally hear my mosfets and clockgens working....its so weird. when i turn prime on it makes a weird noise (not real loud) and when i trun it off it goes away...it is neat! i really need to get this chips cooled though :rolleyes:
im running 2700 at 1.9v :) so far so good. I wanna try to hit 250x11=2750 maybe after i cool these chips and get this vdd some more power i can hit 260xsomething....or more :)
you know what else is weird, after i hit like 2.65, speedfan detected 2 more sensors. who knows.... and one called "remote temp" is the exact temp of my water block. 11c
also, is it bad to disable ACPI? if i want to try it, will it help me? and in wondows XP goto hardware manager and unistall driver for ACPI-Uniproc sys, then reboot and disable APIC in bios and load windows? correct?
Hmm. It's definitely a wise move to cool the vdd mosfet and the six cpu ones at least.
APIC can be disabled by installing another system device driver in controlpanel... the "ACPI Computer" one exactly. Then reboot, you don't have to disable anything in bios!
will acpi help at all? or can it hurt in any way?Quote:

What should it help?! Hmm, maybe you can go a lil higher in fsb, maybe also in vcore, but you may lose a lot of 3d performance. Iirc, at least 3dm01 was showing that effect.Quote:

is it worth it to TEC the NB?
i can hit 260 stable when i set a A/C unit directly infront of my mobo bringing temps down close to 0c....(mobo temps, proc is remotely w/ced) why cant i hit 260 stable without it there? like is it likely the ram or mosfets?
also, SAE do you have an pics of your setup?
I cant boot moore than 255 fsb. DFI Infinity.
1,775V cpu,1,9 vdd, 3,3mem,auto agp, auto bus agp, APIC enabled, ACPI enabled.
integrated ph.- disabled, onboard device control disabled.
Memory settings: Expert, agresive, 52222-13-15-auto,fast,enabled,128mb,enabled,enabled,disabled,d isabled, disabled.
this is on ALL boards. I just got my 2nd infinity today after a 5 month streak with my nf7-s. I immediately applied heatsinks to everything and noticed a black mark on my NB heatsink. maybe its to find out if the user has removed the heatsink? It seems to be just a marker or something because after i washed the nb heatsink with soap + water (instead of using up a whole cloth) the mark was goneQuote:

IMO the NB ain't the thing profiting from the AC units coldness. It's other components like the mosfets and some other small ics and maybe even the traces that can make use of this icy wind ;) The board gets more stable and reliable. But you have to admit it's no 24/7 solution, huh?! ;)
Pics of my setup??? :D Woooh, you don't really wanna see them... and my mess around here :lol:
found out that having com1 enabled makes EVERYTHING really unstable. who knows why. i needed it for my UPS too :shrug:Quote:

ahh come on, show me some pics :stick:
hes got tons of pics in this thread already
That's true, my friend :DQuote:

yeah i highly reccommend reading through this thread i spent about an hour doing it, ive picked up tons of usefull information...
ive read the whole thing more than once....i know SAE has a few pics but i wanted to see his WHOLE setup...cooling and all. not just like shots of mods and stuff
and why is it that everytime i change the ratio to anything other than 1:1 it is unbootable?
the guys over at extremeoverclocking told me its a bad bios chip and i should RMA the board. it works fine other than that though. i have tried even the stock bios and still does it. i have 3 flashed chips (including the bios saviour) so i can see it being a bad bios chip....maybe im just pulling too much from either the cpu or ram????
you dont want to run out of 1:1 anyways, its known to kill bios chips and there isnt much performance difference...
right but i have seen people run higher fsb just to say they can with a different divider...so its not just my board then? cause like i say the guys over at extremeoverclocking are telling me to RMA the board and its only like a week old...Quote:

The problem is probably related to BIOS programming since some boards can run async fine while others cant..
I dont think those guys at extremeoverclocking know much about nF2's.. ;)
