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:

WHAT IS WRONG ?
1.9 VDD
3.3 VDIMM
memtest#5 5 hours 0 errors !!!
that could be your proc is limiting u...or you mobo isn't capable using 250FSB...Quote:

It happens to me...with the default 1/21 my system won't even go on 250Mhz...now using Hellfire 1/21 revision I do Pi on 250 easily..all with the same spec....
well see my bios is good enough hehe...i doubt it's proc,eh ? 250*9...memtest worked fine...
you should tried try that BIOS thing :)...it'd help you...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:

well Im just saying.. Im at 256x10 with 1.7vdd. all air cooling..
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:

That's on the same page (at least for me). bachus shows where to measure...
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:

You can also measure the vcore at the upper leg of the right choke, the one we attach the vdroop mod to...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:

I tried them, they didnt get me anything extra.
L12 on DFI ? HUH ?
