well the "secret" to a high fsb if there is any is a good nb wich depends on luck and defiantely high and even more important stable! voltages (3.3v and 5v rail)
something special with the nf2 is that its newest stepping doest seem to care about vdd anymore, so all you can do to get a higher fsb is raise those rails to 3.7 and 5.7v or higher. to get stable voltages you need good mosfets and capacitors and good cooling on the mosfets if they run hot. and of course you need a good powersupply that produces out stable rails.
oh and dont forget to cool the sb! gave me 5mhz fsb extra and you might get hd corruption, problems with cd drives and network/sound on board related probs.
CPU Interface Disabled makes a huge difference. Let's not kid ourselves, 266 Enabled is a lot faster than 270 disabled. 270 is about as fast as 250 Enabled.Quote:

thi is a shot with a stock coolink and no mod NF7 V2.0, without using any soft/oc, with bios 18 and pc4000 ram
yes, timings are 3-4-4-8 and cpu interface disable, but if you are talking only about fsb this is a better result, considerting that in these conditions the sys can load windows

Ill take thats as a NO then shall I
:mad:
Geez what happened to helping peeps out, that is one of the reasons i love this forum cos peeps are so helpful guess u aint one of them just here to gloat abt your overclock.
Good luck to ya, at least I know what you are like
mongoled
hey mongoled the added safety of sheeps over woman is amusing.
Why do you have to be so quick to get angry? :( I get several PM's a day now about FSB OCing and I answer all of them. Sometimes I don't find time to reply to every post, or perhaps I had decided to reply to yours later and forgot about it.Quote:

Anyway, to answer your question - I think you need to raise your 3.3v rail. If your Vdimm is at 3.6v and your 3.3v rail is at 3.6v, I'm surprised you can even go up to 252 - in my experience, the 3.3v rail has to be 0.15v higher than vdimm AT ALL TIMES to get a stable overclock.
Well what am I meant to say?
I asked for your experiences twice within this thread, I wasnt going to ask you a third time. Every time i come to check the thread i find no response to my simple question.
But i owe you an apology not because you have answered but because I have no right to expect an answer from yourself or from anyone for that matter.
Me tries to chill out

Eck! Throw that chaintech away. Get a real motherboard. :DQuote:

Sounds like a bad week for the northbridge.
Mines a 0308 and does 225 for a few hours to 4 days straight at 1.57vdd.. then crashes for no reason.. mod comming. 8-)
Try to get 266MHz DC instead :). (Must do NB lapping mod... 260MHz++ DC sync, coming soon ;))
something better with good watercoolingQuote:

:D
dirty you have any benchmarls :O
have sandra membench till 277mhz with 8.5x multi, over won't work correctly
at 275-277 give 3660-3700mb/s (don't know why it continuelly change), so i thing a pretty good bandwidth for a 2300mhz cpu and 3-4-4-5 timigns with cpu interface disable...
but as we know sandra doesn't show much real performance in bandwidth, like on intel 1:1 3-4-4-8 VS 5:4 2-2-2-5.....
Do you have any benchmarks or any sort of proof?:stick:Quote:

:D
sounds nice.. but yeah lets see soem benches!!!
and you REALLY should get some BH5 with 3.8vdimm in them and run taht 1:1 2-2-2-5. that will get you the win here. also cpu interface enabled would be a big help. sooooo: lets see some banches!!!
Sandra scores won't do the setup justice unless he has 10x multi or higher. A 3dmark or pcmark score would be kewl though
yeahany benchmark with a cpuz screenie in it also would be enough for me.
If that's real, then way to go Punk. By the way can you show cpu-z memory tab shot. Like Evil_Spork you should get some BH-5 and test using those.
I just hit 271x8 4:3 2.5-4-4-7... Pathetic performance compared to 266 1:1 2-2-2-11, but hey it's 5mhz higher. :)
I thought the question here was CPU interface enabled
not timings xduck. Although i agree that 266 with CPU
interface enabled probably equals 280+ w/o
All these high fsb don't mean much if you have to sacrafice timings and low cpu overclocks. Dirty_Punk were you running dual channel or single? Were you memtest stable at those speeds? What week is you nb? Sorry for all the questions, but I just gotta ask.
You guys are running some sick fsb there with the NF2...... I remember feeling like Im on top of the world when my NF-7 ran 233fsb........ now 280:slobber:
dual channel with a pair of a-data pc4000 at 2.8v, 3-4-4-5 timings and as i say cpu int disableQuote:

memtest never tryed but i doubt that can be stable either at 270mhz
at 270mhz i can do pcmark (at 275 crash) but as i say i must use 1.5v vdd (tryed yesterday and it's more stable).. with 1.7v vdd i can't get 280mhz, with vdd mod up to 2v i can't for example s.pi (at 2v) at 270, but with 1.5v i can s.pi up to 275...
so it's a particular mobo that won't accept hight voltage...
some time ago in this mobo i have done a vddrmod, ad at >3v VDDR the mobo won't overclock at all over 240mhz, with 3.2v nothing over 230...
so it's not a mobo for overclock, only to play a bit with...
Superpi @ 270Mhz? I want to see that!
Id like to see how 280MHz FSB 1:1 @3-4-4-5 compares to to my 246MHz FSB 1:1 @2-2-2-11 sandra score (Stock board no mods btw ;) ) the board and memory are now sadly fragged but it was fun while it lasted. I managed 250FSB but only a 9.5x multi so nothing special but is shows what difference the multi makes when you compare my two scoresQuote:

Xducks acheivement is far more fantastic, 266FSB not only a high number but it also has really low latencies to cope with too, coping with CPU-Interface and tight timings is far more stressful than just a high FSB and slacker timings than a $5 hoe ;)
My complete congrats Xduck, seriously kudos my man :toast: :toast:
