aah your right...But what the hell. better to have too much than too little right?
Got it somewhat stable.. But I don't think it'll be stable in 270 DC.. Never... but I'm sure as hell going to try! :D

I can't get anywhere above FSB221 on my Rev. 2.0 mobo, stable that is, and it's not my Mushkin. I tried 2.5-3-3-6... didn't help. So now I see that I should disable APIC. Should I just reboot, disable APIC in BIOS, format my Windows partition, and then I should get more stable FSB?
I just read somewhere in this topic that the 10.5 multiplier provides better memory bandwitch. Here's my results from Sandra:
11x: 3397/3173
10.5x: 3411/3169
10x: 3384/3146
9.5x 3394/3137
hey TicTac, can you answer this for me,
in what situation would I need CPC to be ON or OFF? I do not know which version of the d10 i want
CPC On forQuote:

You need a CPC ON D10 :toast:
Yes ... you should read the changelog carefully... i already inform that multiplier 10.5 ... got bandwith spikes in it... 1% higher than any other multi :banana:Quote:

what do these settings change/help exactly?
just want to make sure before i go messing with it ;)
This bios kicks ass. I have gone from 231 to 240 stable 2-2-2 timings with only 2.95 volts. Bravo!
I did. I just wanted to share my experience so people had an idea of how muth band width it actually gained.Quote:

Those two are BIOS settings, right? Never touched them before.
I already use D26 Manta Rays XT CPC OFF, but I was actually recommended to try Merlins BIOS because of the low FSB. And what is it about the D10 BIOS? Why are you modding that one, when it's so old?
I'm already at these:
Vdimm = 2.9V in bios
Vdd = 1.7V in bios
Vagp = 1.6V in bios
Just not the V-AGP. Isn't it at 1.55v standard?
How about for 1 x 512MB + 1 x 256MB? :)Quote:

Any tricks? Naah. Used the NF2 Tweaker by tictac and Codered made me get over 260 :) used 1-3-4-3-3-4-4. Some strange supposedly bh-6 mems @ 1:1 2,9-3V 2,5-3-3-11 1t DC of course. My VDD was about 1,9-2V i think. I only had the penn mod at the time. Got my VDD and VDIMM mod done yesterday :) will try later today, send some results. BIOS was Tictacs D26 mantaray XT CPC ON. And the OS was Windows 2k SP4. :) Kan you show us some bench results? :D would be nice to compare :) What's your highest stable superpi?Quote:

Lord_Kvadd,
WOW lot´s of info, very nice of you!
I opened a thread at liquidninjas.com about my FSB quest, you can read it HERE. I recently got 262FSB and this lead me to 4028Mb/s sandra score, will do a search for the screenie on my HDD later.
My info: Super Pi in 34sec, BIOS Tictas Mantarays XT cpc on, WXP SP1.
Regards, KODE.
KODE
That's one hell of a superpi time!!! :D Congrats! I'm only @ 38 although I only have a locked barton. I'm testing FSB on a friends 2600+ tbred with only half the cache, but it's unlocked so :)
Since you've done so many modifications to your motherboard would you like to help me with mine? My vdimm modd's funny. Can´'t get vdimm over 3,04V. Is it the vtt tracking?
Btw. I got it up to 274fsb just now but it's not that stable. Going to add a bit more vdd. Man this board likes vdd =/
Good luck with the FSB!
Thanks m8, I envy your FSB, in a healthy manner of course :) It will be a pleasure to help you with the Vmods, wich Vdimm mod have you done btw, dirty punk (3.3V rail =Vdimm) or the Motherbord FAQ via resistor? I don´t think the Vtt is limiting you, How´s your PSU 3.3V rail at?
I have recently done the Vtt cut trace mod, so I´m still evaluating it´s effects on the Mobo, wil post the results soon.
I just found the 262FSb screenie, gonna find a CD to burn it and post it to you cause my main rig doesn´t connect to www, no Floppy, etc...just CD-RW.
P.S Are you getting 274MHz FSB with only 3.04V or is it a typo? :) :stick:
Congrats on your new FSB anyways!! :toast: :banana: :banana4:
Hi m8,
Here's the 261.7MHz FSB screenie with 11-2-2-2.0 with Dual Channel. Strange thing is 11-3-3-2.5 will not help me get higher FSB not a single one...
@KODE
What vdd are you using?
I have set mine to 1.82 and higher also but i always get SPrime erros after ~1h. with 2,5-3-3-11@2.91v.
I can´t get over 240 wilth full stability.
Hi Golias,
I'm using Vdd at 1.9V. You'll probably need more Vdimm to go higher. Did you try the L12 mod? this mod was always crucial for me.
L12 mod is implemented.Quote:

Thanks m8 :) It was just luck I think. But my mems refuse to go 2-2-2-6 @ 260. They are really strange. Corsair sticks. Supposed to be BH-6 according to Corsair but ever heard of bh-6 that does 250fsb 1:1 2-2-2-6 @ 2,9V? The modd that I did was Motherboard FAQs with the resistor. Now the problem could be the resistor as well, because I checked the resistance and it showed 115ohms. But 100ohms should be more than 3,04V or am I wrong? Your the expert :) I modded the 3,3V rail so it's about 3,4 now :) should I increase it?
And no the 274fsb in 3,04V isn't a typo :) Damn strange ram I have =/
btw. your vdd why only 1,9V? If you get that stable with 1,9V then you've beaten my board :) I think I had like ~2V :) Any more vmodds i should do? Hrm I havm't cooled all the mosfets yet =/
Anyway! Good luck getting higher fsb m8! :)
i use this driver on mine
http://home.doramail.com/tictac2/Driver-293.zip
:D
Nothing that's gonna crash our computers now tictac? :stick: ;)
naah just kidding :) gonna test as soon as my sis and parents go to bed. I'm supplying internet thru my computer and any restarts and the internet goes down and this is what my sister will do to me :frag: and :cussing: ;)
what's that driver for tictac?
memory controller driver , AGP driver and pci bus driver
I'm running on it now... no problem... :D
Increased bandwidth or something?
worth me installing?Quote:

That's because not enabling quick post makes your comp check the RAM every boot.
I'm not sure about the 2.7V thing, though.
PS: I'm going to vmod my mobo sometime soon, I hope, so I can get in on some of this crazy FSB action. I want to break 24K in 3DMark2001SE. I think it's possible... :devil:
Thanks for making these BIOSes, Tictac! :toast:
Yeah bit why does it just keep on going. How many tymes should it cycle through before deciding the RAM is ok?Quote:

Max fsb this board will do is 230mhz, and to run that at 2,2,2,11 I'm using a DDR
Booster, so vdimm is running at 3.1v.
EDIT I've got this in system props : apic uniprocessor driver
Does that mean I've got ACPI off?
Oli
ya it will cause 3d mark performance drop... but if you planning to run it at high clock high voltage & High FSb... the APIC need to be disabled.... or it will get unstable and IRQ crashing
that is common issue on NF7S APIC mode :D
juat go update the driver to ACPI ... that will do the job :banana:Quote:

Sorry if this is a bit OT; I asked it once before and it got skipped over. :(
Anyway, I'm looking at putting a mobile CPU into a rev1.2 board soon, and so I don't know what the results will be.
But my question is: Is there a modded BIOS for the rev1.2 NF7-S?
i think there is rev1. modded bios
but not FSB bios... just cpc off bios @ pcperspective forums
Hi,
I am trying black manta d26 mod at the moment and I would like to know witch bios mod is good.I tryed Manta XT but Ram volts kept changing between 1.7v to 1.9v? is this bios bugy??
CPU: Amd XP-M 2500 Barton
Stepping: IQYHA0407VPMW
Motherboard: ABit NF7-S v 2.0
Cooling: Vapochill pe
Temp -17.5@18c idle -15@35c Full load
Default Voltage: 1.45v
Overclocked Speed: 2756MHz (13 x 212MHz)
Overclocked Voltage: 1.975 volts (Bios)
Regards Vapo
Merlin taipan is good big bang bios as well :)
Manta Rays XT no bug as far as i know...
I have placed this post in two places in a hope find a fix for this problem.
I have put down the wrong vdimm volts thay should read 2.6v to 2.9v. I am sorry for the suffup.. The problem is still the same as the you can see on the attachment.
my vdimm keeps changing. Some times I can get 2.9v next time I get blue screan ram reboot its on 2.7v and there is no 2.8v or 2.9v listed? This is not good how can I get this fixed? I have to run slower colck because vdimm keep on changing?
I need to fix bios first then I will do the mother board mods. How can I fix this problem?? The over-clock is good but the vdimm is bad.
Some say to stay away from the L12 BIOSes, especially if you have the hardware L12 mod done.
No Mother Board Mods(Bios Only)
CPU: Amd XP-M 2500 Barton
Stepping: IQYHA0407VPMW
Motherboard: ABit NF7-S v 2.0
Cooling: Vapochill pe
Default Voltage: 1.45v
Overclocked Speed: 2743MHz (12 x 228MHz)
Overclocked Voltage: 1.975 volts (Bios)
reflashed the bios again....
2.4v = 2.6v
2.5v = 2.7v
2.6v = 2.8v
2.7v = 2.9v
they have same voltage .....
2.4V wont give 2.4v real..
if enter bios just press del... dont press tab & deleted
This is how it goes. Use recovery diak 1 flash bios everything is good.
Flash bios with Manta Ray XT L12 cpc on, D 26 Black Manta L12 and it is as you see. Will try std bios and then try new down-loaded bios.
Befor flashing from D26 black manta it was normal after what I got the problem.

well I fixed the bios. :banana: it was bad down-load.
Q 1 witch bios to use
Q2 cpc on or off
Q3 with L12 bios or not?
Will do vdimm & vdd mod this weekend and hope all will go well, What can I expect??? may be able get 240 x12 would like to get 245 x12 this would be nice :D

1. try d26 mantaray XT
2. only use CPC off bios if you have 2x512mb .. if you have 1x 256, 2x256 or 1x512 then use CPC on
3. i think all these bios come with L12 softmod anyway
can someone say me why no bios with integrated l12 mod works for me?
i have a 2400+ , 2*256 bh5 ram nf7 2.0
In my experience, the BIOSes with built-in software L12 mods have not worked at all. The only way that has worked for me is to do it like this.
Using one tiny unraveled strand from a piece of wire in a U shape, shove it in the two holes shown in the pics there and put your CPU in. Voila! With the right BIOS and RAM you'll probably be able to get around 230MHz FSB stable.

Just have to say the XT bios is super! :) Running 10.5x235MHz atm. Timings are 2-3-3-11 with CPC ON. With CPC off I can run with 2-2-2-11@240MHz but performance suffers bad.
Golias: Use 2-3-3-X timings instead of 2.5-2-2-X.
Edit: Would I gain much with a VDD-mod? Or perhaps some cooling on southbridge... any ideas?

I'm not sure if I should use CPC on or off. HalfLife2 fails either way after a while. I get the common memory problem. It seems more stable with CPC off. I haven't tried the other games after flashing to Mantarays XT cpc off. Will do that later.
What is APIC? May turning it off make it more stable? I see tictac talking about a APIC processor driver to install and then turn off APIC in the bios. Where can I get that driver? Anyone got a link?
What is the PCI latency = 128 clck and Ext p2p discard time = 1 ms. What does it do? I saw someone getting poor gaming performance using this.
My system:
Abit NF7-s v2.0 1,7v
AMP XP-M 2400+@2578.5 (11.5x225) 1,90v
1x512MB CorsairXMS3200 Winbond
2x256MB TwinMos3200 Windond
2.0-2-3-11 Dual Channel 2,9v
I know the CPU can take the speed. I used to run 12x217 before I got the Corsair chip using an old stock Bios. Seems like the 512 chip is making it unstable somehow. I know the chip can take the speed too. A friend ran it at 275 once. I want 1GB...it's sweet. I have tried to run at 12x200 too, but it did not help.
Try these:
-increase your AGP Controller Latency to a higher number (default is 32). try 96 or even 255.
-bumping your Vagp up to 1.6 (if u feel u need it).
-go from 66MHZ to around 69MHZ for AGP Speed.
-changing value of tW2P & tR2P to 4.
-upping or lowering vdd.
u can use the nforce2 tweaker to modify the AGP Controller Latency setting, tW2P & tR2P.
http://indabasement.com/tools
PCI latency (depending on X number) gives devices more (or less ) time to hold on a channel (for X), before it relinquishes it.
you can turn off apic within windows (start->settings->control panel->system->computer->update driver->advanced configuration and power interface)
CPC (Command Per Clock) Off = Command Rate 2T.
CPC (Command Per Clock) On = Command Rate 1T.
for 2x512 or 2x256-1x512, cpc off wil give more breathing room for the ram to expand in fsb (usually) by addressing the banks at a slower rate.
good luck.
Thanks Pershoot :)

I haven't read the thread, but how does this BIOS stand up to the D23 fire in terms of speed? Also will it let me use the 11 or 11.5x mutli?
Yes it will :)

nah dude.. listen to what prime is telling you.. at least for a few hours.. i know i know.. its a paint in the &*^*%, hehehe, but if it fails within 5 minutes, you have an instability somewhere and it will crash and give errors (when all depends).
