Last night i moved back to d10 BIOS and droped down VDD to 1.75 Volt....
Now? 250 FSB 100% STable and still dont believe it.......
I want more but 1.0 has 250 as top limit FSB.....
Just Take a look.....

Last night i moved back to d10 BIOS and droped down VDD to 1.75 Volt....
Now? 250 FSB 100% STable and still dont believe it.......
I want more but 1.0 has 250 as top limit FSB.....
Just Take a look.....
But i like for 24/7 246 FSB whish give me MOOORRREEEE Performance.....
nice! i wish my mobo would do over 182fsb LOL.. thats why its getting RMA'd tomorow!
Good luck.......
And just remember to try BIOS d10 (for Ver. 2 NF7) and see whow it goes......
You will find alot of Performance hidden right there....... :D
Now my main target is to have 250 X 10 = 2500 MHZ stable 24/7....
Since now all are ok but 3D is not working well...
Probably need a litle more VDD juice like 1.80 to 1.85 to have 3D World back to action........
We will see........... :banana:
Thats verry nice. What timings are that in and are all things stable(like memtest86 and prime) at 250 except for 3dmark?
get a chip that can do more than 2.5Ghz , then you will have the 250*10 ;)
btw nice NF7-S, can you tell us what mods you did ? I mean Vdd mod, Vdimm mod, rads on mosfets, zalman32NB on southbridge , special cooling on northbridge ?
For 250 FSB i set timmings at 11-3-2-2.5
For 246 FSB i set timmings at 11-3-2-2 and was stable.....
I also tested 11-3-3-2.5 to have stable 3D at 250 FSB but no luck until now....
I will raise VDD up to 1.8-1.85 and redo all Becnhes from begining...
The BIOS 1.0 goes from 245 FSB (246 measured with CPUID) directly to 250 without midle steps like 246 - 247- 248 - 249 and this was another problem.....
But since now all are running very stable and FFFFFAAAAAAST....... :banana: :D
so you aren't at 250 100% stable.. if you aren't 3d stable you aren't stable at all
try 7-3-2-2.5 settigns, all the memory i have tested lower the max clock if i set 11
your using the 1.0 bios on the rev2.0 board???
Before the downgrade from d18 to d10(for Ver. 2 NF7) BIOS i had VDD up to 1.95 for a stable 242 FSB...
Now with 1.0 BIOS i have VDD mode back to default voltge (1.75 Volt) measured with my digital multimeter.....
I dont use any other MODS (VDDR - VCORE e.tc.)
I have stock cooling on it but AS3 under Heatslink and Passive Cooling with a Simple heatsink on the other Bridge.....
Mosfets are not using extra Heatsinks.....
I guess i am VERY VERY LUCKY :D :banana:
Holy poop!
Mine doesn't even like anything over 210Mhz, good going man!
Lets clear this .....Quote:

I am 100% stable at 250 FSB but with a multi set to 9.5 which give me 2375 MHZ which is not what i want........
When i set 250 FSB X 10 = 2500 MHZ then all running fine even Prime 95 - CPU TOAST - Fast PI - SUPER PI but 3D applications after a few minutes just closing .....
And seems to me needed a litle more VDD or a much effective cooling to the Chipset........
;) :toast:
PS...... If any of you have same mobo Ver. 2.0 just try to Flash d10 (for Ver. 2 NF7) BIOS and findout what will happend.....
If this confirm my success then we must ask from ABIT to give us a new copy of this BIOS with SATA correction on it and leave all the other code back to original d10 (for Ver. 2 NF7) BIOS....... ;) :D
Is a good IDEA.....
it killed the board of a friend ;)Quote:
If any of you have same mobo Ver. 2.0 just try to Flash 1.0 BIOS and findout what will happend.....
well he needed a new bios chip that was all... i really wonder why your board is still working... :stick: are you sure its the 1.0 bios? where did you get it? i heard of 2 other people already who tried to flash their 2.0 boards to 1.0 and they board wouldnt post after that...
please post a link, i wanna try that bios when i get my nf7-s 2.0 back.
I always doing flashes with ABITs Flashmenu utility and is working perfectly.....
There is a note on ABIT homepage that is not able to reverse to any BIOS prior to d14 if i remember well but this is not true when you are using flashmenu utility.....
The most importand of all if before you make a flash ALWAYS you must be sure you are with 100 FSB and remove from memorie any aplication is running......
Since now i've made up to 20 - 25 FLASHES with this board and many many more times BIOS reconfiguration and until now thanks GOD all running well........ :banana: :D
some people use bios 10 with rev 2.0, because bios 10 give much more overclock VS bios 14-16-17-18, more bus & more performance, and there is no problem to go back to bios 10, use winflash
he did use winflash, he was on tha 16 bios before because i told him it works best for me. he used winflash to get the 10 bios flashed, all went fine, need reboot window popped up , but it never booted again.
i heard of some special commands to get back to 10. do you mean that? or did you just use a floppy with the 10 bios to boot and hit alt-F2?
try the L12 mod + bios 1.0 => nice combo for 230-240MhzQuote:

I have my 1800+ all ready to go, just waiting till I have the time to pop it in, prolly on saturday, unless I snap and stick it in tonight.:D
Here's hoping I have enough AS3 left!
Please dont make me think i have the GOLDEN SAMPLE on my hands because i dont believe it.....
Abits flashmenu have all the options you need for a safe FLASH.....
I remember a day which flashing procedure just freeze in the middle of flashing and after a Ctrl - Alt - Delete combination i end task the flashmenu and restart again flashing.....
Even with this bad situation still working JUST FINE..... But NEVER i mean NEVER forgot to make boot at 100 FSB before do a FLASH Procedure....
So i think if you want to try you MUST be FLASH back to d10 (for Ver. 2 NF7) BIOS....
The risk of a Bad Flash always will be like ghost around us.......;)
With 246 FSB and 10 multi all 3dMark 2001 & 2003 passed at default card speed...... 400/850 GPU MEM for my fx5900 by Leadtek..... But is not the higest scores i got because i dint try yet to push more....
I have a lot of tests to do before find the best FSB/MHZ combination for a 24/7 use.......
Here i post just the begining of a happy story and just wait to see the happy ending of it..... ;) :D
Yes. Wanna see. My ram single sticks can easily do 243 2,0-11-2-2 at 3,17V but in dual channel... that's another story :rolleyes:Quote:

At least with multi above 9,5... :(
Interesting thread. I never did inderstand why we had to sacrifice this performance when they updated the bios from 1.0. Please send this thread to Abit.
That is very good. Get some good memory and you will ok to go.:D
how about some benchmarks finally ;)
Super PI, Hexus Pifast, Sisoft sandra mem test, PCmark.
those I'd be interested in seeing :)
I believe MickeyMouse was talking about having both CPU Fast decode + 128bit DC all at the same time. There are only very few people that can do 245~ 250 FSB with all these enabled. Everytime when I compete with others who have higher FSBs than I, I beat them in the benches. Most of them people disable Fast CPU decode to gain more FSBs. Dual Channel isn't the only thing here. Having both enabled is what makes it difficult and challenging. There is no such thing as "free". You will have to give up some to get some. I really am not trying to offend anybody here but I really thought I should point this out.
250mhz FSB DC + FastCPU decode + 128bit DC, here it is:
No, this is not mine. This is the member "Learn" who achieved it several months ago. And that's with Tbred chip, not the Barton.
http://membres.lycos.fr/ftpad/images...fsb250.57R.png
I guess I can't try that as I have hyperX ram... Unless I'm mistaken the incompatibility was only fixed with 1.4 or something like that... :(
like this
http://digilander.libero.it/DirtyPunker/250DC.jpg
a-data pc3200 + v-data pc2700
3.15v, 7-2-2-2.5 DC Cpu int Enable
VDD 1.7v
but don't know why i have 10mb/s less... probably v-data pc2700 is a little slower than xms pc3500..
I haven´t tried the 1.0 yet, but with 1.6 i can run:
240 2-2-2-11/5
246 2-3-2-11/5
this is with stock NB cooler, DC and only 1.6vdd.
If i try 250 (no matter what timings) it just reboots, and im pretty sure its my RAM holding me back. 2x256 Twinmos /m Winbond BH5 which i paid 30$ for each a few months ago, so at that price i dont complaint.
Need some faster memory, but where to find it :confused:
Hmm. The 10 didn't cut it for me :(Quote:

But I am stable with the 18 :eek: at 11,5x240 2,0-11-2-2
But I absolutely cannot believe you only needing 1,6vdd to do 240 dual channel 3d stable :rolleyes:
P.S. What does the /5 mean you wrote behind the timings?
Very nice :toast:
I can do 250MHz stable enough for all kinds of "cpu/mem-tests" too.. Prime/spi/pifast and so on. 3D on the other hand is a completely different story. Not sure if my setup can do it at 250 at any cpu-MHz but it sure can go a lot higher on the FSB when the CPU clock is lowered.
Also I agree that bios 10 is a very nice version ;). Using beta 14 atm tho.. that one and 10 are the best in my experience (havent tried the newest ones though).
Im using some bh-5 mem myself and they can take any timings at 250MHz with no problems at all. As long as Vmem is about 3,1V+ or so.
I agree.. either your stable, or your not stable. When i say stable i mean, 3d stable, prime, super pi etc. If it aint ROCKstable, it ain stable..Quote:

I think it depends on what bios comes shipped....... once you flash 14 or above they say there is no going back, but there are workarounds for that (force- and I THINK WINFLASH works also ).Quote:

please post a link, i wanna try that bios when i get my nf7-s 2.0 back.
I have a 2.0 and flashed to 10 and haven't had any problems, then again my board came with 12, so there shouldn't have been any.
My first 2.0 came with 11 and I flashed to 10 ...there were no issues there either.
I can't believe it, i did litterly everything to get 240 FSB stable, but still no joy.
Here's the list:
Flashed to bios d10
Modded 3.3V on PSU up to 3.44V
Vdd modded, up to 1.92V
Vddr modded, up to 3.23V
Sinked mosfets and SB
Lapped NB and put Crystal orb on
Tried Twinmos BH-5
Tried Twinmos PC 3700
Bought new PSU, thought that my Qtec 550 didn't cut it.
Did i miss something?
It just won't let me do 237 or higher stable...
I'm leaning towards the idea that somehow it must be either the CPU or the mobo.
Any idea's? I'm all out. :(
very nice job mult 10 will be very very nice :toast:
Jason, i tried bios 18 but if i got somewhere around 230, my system locked up at opening any app. every time.
Increasing Vcore didn't help here.
Unfortunately my CPU is at it's max with 11x230, so i have to make do with multi 10 or 10,5 for real high FSB
Don't know about more Vdd, look at the one who started this thread (Dagalidis), he only runs 1.75Vdd... :confused:
You got a point there mate, but to run over 2V i think i need to improve cooling like you suggested, a pelt would be nice...Quote:

2% use under 2v for 236+ I have 172w tec cooled three and had to have 2-2.15v for 240+ and the back of the chipset was at -17c load ;)
That's right, guess i'm never lucky when it comes to pickin hardware, my target was to get 240 stable at least but if the board doesn't cut it i have to live with that.
No point in getting another one wit the A64 around the corner..lol
How high can you get your current rig FSB wise?
Neither would i if i could get 236 perfectly stable... ;)
I will try some more, maybe i'll increase Vdd some more but for now i'm done.
I've got some time left to improve on my setup before it's A64 time. :)
Do you think multi 11 and higher are more stable than 10,5 and lower?
lol 12 is way too high for me, 210x12 won't get me very far i guess.
OK I've been very hesitant about flashing to bios 10. I was running bios 18 10.5 X 230 2,3,3,11 100% stable. I flashed to 10 and now running 10 X 240 2,2,2,11 100% 3D Mark stable. and this is with no vdimm mod. I know it's no big deal, but it's sure is better then 18.
oh well here's hoping for more....
10 bios was the trick for me. I could get 230 stable with 18 or 14 and 240 with the 10. Too bad I screwed that board up trying to do the vdimm mod. @ 240 I should have just left it alone but I had to try to get just a little bit more! I also saw an erlier post asking if you could go back to 10 from 18. My board came with 18 and I used Awardflash with parameters " /cc /cf /ff " and it flashed back to 10 with no problems.
hi guys,
am new to abit... i just got my abit nf7-s rev. 2. from abit site i see three flash utilities :
1. Abit Flash Menu
2. Abit Flash Utility v8.23k
3. Abit Flash Utility v8.24F
which flash utility do i need to flash back to 1.0? my board came with the 1.8 bios.
Thanks
My mate on the forums here Ragnarok can prime and 3dmark at 243fsb 2-5-2-2 with CPU Fast Decode on with his 2x 256meg XMS3500 Rev 1.1 and 3.05vdimm on an NF7-S Rev 1.2
Ill get him to post his results :)
ps
Might be 241 or something, but I do know it was over 240....and with 1.7vdd and iirc, default NB cooling :banana:
anyone can get 250mhz stable??
because i can get up to 246mhz 11-2-2-2 and seems prime stable, but at 250 doesn't matter how many vddr (up to 3.26 with vmod, over 3.26 it's too much unstable, change from 3.14 to 3.3v...) or vdd i set (up to 1.96v with vmod) but nothing work...
at 246 i set vddr at 3.17v and vdd at 1.8v
i have also chipset watercooling with 3° water
so 246 seems prime stable (never tested a lot) and 250 won't do sandra memtest!!!! :rolleyes: :mad:
any advice?
i am 90% stable at 250sc 2-2-3-11 with my twinmos 3700@3.3v and 1.75 vdd. i can run all benches and proggies and games, but prime and other stress tests make the system crash after some time. i guess i can run dual channel, but my khx 3500 doesnt run 250 even with bad timings and 3.6v...
a7n8x deluxe rev2.0 btw
Well i don't think you have much reason to complain, now do you?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??
im sure i can do 255dc or even higher but i need better ram :(
sweetness it seems you and i are on the same page. The minute i turned my sistem on i proceeded to go up to 250fsb and later started playing with 10x246 what processor are you using? again i used a 2600
AWSOME!!
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:

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:

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:

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 :(

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:
my pc crashed at 245dc 2-2-3-9 3.3v vdimm and 1.74vdd with delta on a7n8x nb hsf after 4 days. i was playing a few hours et every night, on sunday i played et for 7 hours and i got a bsod... could have been the 8500 as well... the waterblock is just laying on the pci slot, its not fastened to the gpu at all :D
Ok, just some more proof that high Vdd isn't necessary, don't mind the score's though, VC was at stock speeds.
This was all run with just 1.7Vdd, 10,5x230
Haven't tried higher yet, just wanted to see if it was 3dmark stable. ;)
edit: you got a point there, Jason, still i think 1.7Vdd can take this board very high, anything higher than 1.9V requires some real good cooling to the NB i reckon. (pelt)
No. Not necessarily a pelt. Just ensure you lapped the nb fine and pray the mosfets won't blow ;) Water or a decent cpu cooler is enough.
But never heard of an abit nf7 blowing mosfets... Sometimes had 2,7V through my 1.1 :rolleyes:
Last one was the best one i ever had, doing 230Mhz w/ bios 1.6 stock and reporting the voltage exactly the same as the PSu's rails are measured, overvoltage on Vcore and 3.07V Vdimm stock :eek:Quote:

but when i decide mod it to extrem lapping, watercool, etc this one was running sweeeeet but by error I decided to measured some Vcore at Mosfets ... error, i short circuited two legs, then the mobo wouldn't boot :(
The one i'm using is completly different although the northbridge is the exact same week :/ it couldn't even do 200 Mhz stock, but atm i 'm benchmarking some 240Mhz with it ;)
What nb week was that???Quote:

Had a similar board I killed with a vdd mod in the dark ;)
Did it and got my 7th rev2 then... :rolleyes:
But none that good again... same nb too...
Somebody knows if these with the week23 nb perform better? Board circuitry is always luck of the draw :(
Thx again.
my two last were week 16, hopefully , i've my rma return in 2 weeks, prolly i ll get a new week :D
2.7V?? :eek:Quote:

You must be the most careless overclocker of Germany..lol!!! :D
Never heard of blown mosfets on Abit mobo's myself, this seems to be an Epox issue...
Lapped the NB nice'n flat but i think this Crystal Orb isn't up to the job, even though it's one hell of an improvement over the stock cooler.
The stock Abit cooler pushes 3.5cfm against 12.4cfm for the Crystal orb.
If i go over 1.85Vdd i get bluescreens all the time when i hit high FSB which gives me the impression the NB needs some serious cooling at these voltages. ;)
Since you've been trough quite some NF7's and achieved some nice OC's ( :slobber: ) i assume you know what you're talking about.
Must try some better NB cooling then, for now low Vdd seems to do fine. :)
Damn, how do you quote 2 people in one reply? i'm a n00b...Quote:

What a shame of your last board mate, sorry to hear that.
I always have a piece of small tube over the pin of my red probe, just leaving the very tip bare, works great every time.
I killed a NF7 a few weeks ago by having one stick of RAM pushed halfway out of the slot, i think it happend when i inserted my videocard, killed one of the 2 memcontrollers.
The board just got every mod one could come up with, so i know how it feels...:( :(
Keep me informed what you're up to with your new one. ;)
Yes. I think I know :D
Careless :confused:
Hmm. :idea: I think I got it. But you are wrong. I could not get it right this time cause I read out a standard vdd already around 2,17V when set to 1,7 in bios :eek: So I assume it was a readout error. Later after some board swapping I could get it right. Maybe the pot was... crap :D
NB cooling is important. But not as important as you should go for pelt or vapo on it ;)
I found a nice one in the komplett online shop. It states mcp-t2. Do you also think it's rev a4 sb???
Maybe I'll order one - or get a new one from a friend at k&m??? With wk23 nb! I am clueless.
Sure, go and get nr8, lol!! :D
Don't know what the heck mcp-t2 is supposed to mean and also i'm not so sure wheter later NB steppings will necessaraly be better.
Pc ice recently got himself 3 new NF7's but none of them could really satisfy him.
Btw, i thought you already hit 250 with your current mobo?
I personally prefer opening multiple windows per right klick on the quote button of those ones I wanna quote :DQuote:

Yeah. I did. But I found out lately my ram can take 250 single channel at 3,23V and that with memtest for windows. But I never get that dc stable with any vdd up to 2,26V by now :(Quote:

So it must be stability probs of the nb :rolleyes:
Highest i can get dual channel is 496, the highest i can single channel is 512. I cant figure out for the life of me how to 500 dual.
Pc Ice is going to let me play with his 2 new nf7-s's before he takes them back. Well see what i can do with them. He has them fully modded 3.3, vmem, and vdd and still cant get over 230 dual. Ill post some screenies of my 256 if you guys want. I have two sticks that will do 500(single channel) but one of them will do 512.
Screenie's are nice! :)Quote:

What timings and multi? CPU interface enabled?
256FSB is cool, shame it won't do DC. :(
Sigh... :rolleyes:
I am at memtest for win for 2hours now and no error at 252MHz 2,0-11-2-2 3,23V on one of my twin/wb in slot3 :slobber: If there are no errors here I can easily do prime in my exp.
Single I can do that easily but never dual :mad: Watch the timings :)
Have two other twinmos laying around waiting to be tested the same way. For that I'll use slot2. When putting them in together... I wanna cry when... erm, nevertheless I wonder if the newer boards like sold on komplett.de (seems to have new sb a4 - mcp-t2 stated) would do fine? Such fine that I can up my dual channel mhz a bit :D
I don't mean memtest86, I am speaking about memtest for windows.Quote:

Try it out. :)
lol
Never mind :D
I take it that Mem Test is a good burn in Proggy too?
I usually use Sandra and loop it 1000 times, but is this better?
I dunno.
Over the last couple nights i've looped my ram in sisoft for over 5000 times at 3.23v... burning in for when my nF2 board gets to visit my case 8-)
Yes. I assume it's good. It seems way more sensitive to mem errors though ...Quote:

If you don't use a burn in speed 100% stable proggie's goin' to drop you out of loop - Error. Should replace Ram - :D
But I also have read somewhere here in the forums about it being more intense and way more effective in burn ins :)
To me this is a proof that it's the NB that can't handle DC at such speeds.Quote:

A single stick only transfers half the amount of data to and fro the NB that 2 sticks in DC would do.
The NB just can't handle the stress from 2 memcontrollers givin and askin data.
Maybe some very good cooling on the NB could make a difference but honestly i have my doubts on that. :(
It looks like 240-245 DC is the absolute max for these boards.
If i'm talkin out of my ass right now, it must be the few drinks i had tonite...sorry ;)

Same with the 3/3, 4/4,5/5 and 6/6 settings, never found one to be more stable than the other or yieling better performance. ;)
whats the difference between 3/3 4/4 5/5 6/6????
They all look like 1:1 to me.. lol.
