246x10 is what i usually benchmark in... What memmory timmings are you running and is your cpu interface turned on or off. i can seem to get my to oclock very high with it turned on.
It seems like you have a cherry board!

Are you sure those were taken with CPU Interface on?
At 240MHz, 11-2-2-2 and Multi 10 I get easily over 3600 in Sandra.
Not dissing, by the way, just wondering, I don't think I could bring myself to diss a 246MHz FSB overclock. :D
oooh, damn you and your extra MHz. :D
Nice going Jason!! :toast:
Have to agree with st0nedpenguin, 240x10 has got to yield over 3600mbs, unless CPU interface is disabled.
What stepping is your NB?
Mine's 0311 A1, it might make a big difference.
i'll try to raise +3.3 rail, that now it's a +3.34v and vdimm fluctuates a lot...Quote:

246 stable is one hell of an achievement! :slobber:
There aren't many that have ever gotten 250 stable i reckon.
The only thing i can think of is heatsinks on your mosfets if you haven't done that already, or increasing your 3.3V rail.
Check out this thread, it makes some interesting reading:

Can you do 3D mark at 246MHz??
after i'll sink the mossfet, but i don't think that it's necessary..
3dmark haven't tryed because now i'm using a tnt2 m64, so if it's stable with this board doesn't mean that it's stable with a ti4200 (my real card) or better
but the strange thing is that 246 prime stable and 250 doesn't do any test!!! if i try sandramem at the finish of the test it crash...
with less vdd i can be stable till 242mhz and i can bench in sandramen at 250mhz... till don't understand what's the problem...
I can also do 245x11,5 (gives 246) with 3,18V, 2,11Vdd and timings 2,0-11-2-2...
Also did a 250x11,5 same settings, but everything above 245 in bios isn't doing 3dmark tests dragothic and lobby, only car and nature...
Maybe the nb in its current version cannot get that stable
:confused:
My 3DMark below is with 244 cause my barton cannot pass 3dm2k1 at higher speeds :rolleyes:
BTW. Killed my raddy today taking off the little v-reg heatsink. Broke three of four chips :rolleyes: Rma time... as usual :D
P.S. NB rev is C1 week 12.
P.P.S. Multiplier 11,5 does deliver relatively low bw. I know :rolleyes:
tut, tut, tut... :DQuote:

How many have you killed so far?
Yeah, i know that feeling of Sandra's bandwidthtest crashin in the end! :(Quote:

I once benched this test @ 10,5x242 cas2 and it finished and gave me 3704mbs,when i tried to save a screenie it crashed and gave me a BSOD! :mad:
I think a good and OCed videocard will put much more stress on the NB because more frames/sec means more data.
I tried 1.97Vdd but still to no avail, 240 is still by no means stable.
Are you telling me that with less Vdd you can do Sandra's bandwidthtest at 250, while you can't when you up the Vdd?? :confused:
If that's true, at what voltage can you do bandwidthtest at 250?
I'll try some myself....;)
Ps. Is C1 NB stepping superior over A1???
with 1.7v, so without vdd mod i can bench up to 250mhz...
i don't know the NB step
Wow that's really weird!
That's a bit like Dagalidis stated at the beginning of this thread.
Gonna try myself right away!
Thanks. ;)
Dirty_Punk, you are my hero!!!!!!
Look what i got with only 1.59Vdd!!!!!!
The less the Vdd the less the BSOD's, it seems!!
Maybe i misspoke. i could run 250 fsb with user inerface on but it's highly unstable couldnt run nothing, therefor useless.Quote:

had to turn it off to run anything.
Yeah, I haven't tried turning it off myself, might be worth it just for a 250MHz screenie.
And Dirty_Punk, looks like I'm going to be dropping my chipset voltage for some testing tonight. Cheers! :D
My PSU used is in the sig :) Still on my lovely Antec PP-412XF 400W. Cooling on nb is plain warm water (mcw50-t warms the water and it does not matter ;) ) but nb is lapped to avoid bad contact errors I had some time before... :rolleyes:Quote:
Originally posted by MickeyMouse

Ambient temp is around 20°C rising when stressing my prom :D
I wish I could up the 3,3+ a little more cause it sometimes drops to 3,39V most time staying at 3,42 to 3,44V. Wish to use 3,6V... :slobber:
But as I mentioned 246 in bios can run lobby and dragothic in no circumstances :( Flickers on load screen, then drops me to desktop...
I have only killed a ti4600 with a screwdriver by shorting it :rolleyes: - was absent, watching tv between :DQuote:

The ti4200 ... hmm that was my girlfriend's cup of tea :D
My first 9800 killed... so far. Was one of the first ones though, stock core voltage was 1,73!!! Hoped I could kill 'er without being able to see it from look ;)
Hopefully I'll get a good ocer.
P.S. My 250 was more stable than for just doing a screenie. I think I could run superpi as well... but don't remember exactly. That was with my tbred.

well i went with my friend to make a webcam-recording of the 260Mhz boot on NF7-s , but i couldn't boot it , dun't ask me why, i personnaly don't know execpt than yesterday i change the standard HSF of the north with my waterbloc.
I didn't lap this north, perhaps that s why ...
BTW, during the test, the 250Mhz wouldn't boot until i got the Vdd down from 1.86V to 1.56V (actually i got +0.16V with vdd mod, and can't lower it more)
these NF7-s behave different a day from another ... try to guess why ... turning me mad !
Talkin'bout day to day behaviour...this is really wierd! :confused:
Instead of increasing seems lowering Vdd to stabilize the OC.
Damn, i could even run Pifast @ 10x244 and also SuperPi, only with 1.59Vdd (set in bios to 1.4)
I tried to run SuperPi @ 10,5x242 but unfortunatly hit the ceiling of my Barton.
Just one more screenie to brag :D :
Hmm.. maybe run 2v+ for a a week as a nice burnin then drop it to rock bottom.. for killer fsb's? 8-)
thats weird. it looks like they(NF2) like high V's then after a while, low V's...... gonna have to see what happens when I lower my VDD..
error !!! Lower voltage is faking better stability : be carefull, just have the onbaord APU enable and play some MP3 during your tests, you will see what i mean ;)
BTW, my NF7-s seemed to act better with lower Voltage, but with 1.56V, i lost the APU after few seconds and the NF7-s will "lag" (can't find a better way to explain that behavior ;) )just upping the Vdd up to 2V resolve partially the troubles.
When i say the NF7-s will lag that means that :
-MP3 stop playing
-if you try to bench memory bench, you will lost about 100 pts with sisoft
!! be carefull guys ;)
Always tweaking this NF7-s
Cya for better news i hope :(
Xigfrid
EDIT : just after few more flashs and benchs : it seems that this laggy behavior as some consistence with cpu disconnect on/off , in bios 1.0 this option is not available, so if it was enable before flashing back, your computer will lag, if you have it disable before, the computer will not lag , but will freeze if the chipset over heats.
Haven't noticed...yet, i don't really need to play mp3's when i'm benching...lol.
I ran bandwidthtest @ 1.59Vdd and got 3705mb/s @242, can't say i'm really missing 100mb/s, can i?
Haven't looped any 3d mark at high FSB with low Vdd but @ 200FSB it did just fine with only 1.59Vdd.
I hope it was just indiviual, cause i get BSOD's if i run too high Vdd. :(
i can run 250dc without any 2v burn in sessions.. 1.75v vdd only...
I doesn't care until the mobo melt like you, but the point is to find a good V to have at least a 24H/24 sweet stable o/cQuote:

This NF7-S i'm on is only 1 week old and it has fresh Vdd & Vdimm mods, north/south cooling. I will try every up 0.01V until i reach stability or the melting limit :D
NOTE: I've measured the effective southbridge-Vdd on the resistance in the back of the mobo and it is exactly the same as the northbridge-Vdd :toast:

Do you mean increasing Vdd automatically raises SB voltage?Quote:

I had a doubt about that few weeks ago, and with the new NF7 out of the case , i measured it :D
I was never too worried about the SB, never had any signs of it crappin out, but just to be sure i epoxied an old GF2 heatsink on it.
What Vdd are you using atm and how high does it take you?
Oh and btw, a new mobo, why's that?
You killed your's? :confused:
