I've seen 270Mhz in windows@ 5-2-2-2, but it freeze in a minute.
260 is quite stable@ 260Mhz, 5-2-2-2-2-12-15/3,4V screen

My bh-5... I also was in win2k at 270 but with apic off. my later benches were all with apic on and using 8rdavcore to up the clocks as I did not boot higher than APIC would let me into windows. Now you are saying you could get into windows at ...-12-15.
But you said "9"-15 before... at these settings (the first matters) I could not get into windows. My fsb was 264+ benching stable as you can see in my sig ;)

Hi,

I want to do the Vcore mod, but I don't know exactly what I have to do, I found this :

http://perso.wanadoo.fr/kant/images/...ratotalmod.jpg

But this isn't very clear, I want to have min 2.1V stable.

THX

You just won't get 2.1V stable (minimum) as these boards can give 2.08V stable max... and that's with all the mods.

The vcore mod involves soldering a 47/50k pot between leg 7 and ground. That's it. VSense does nothing. Vdrop stabilizes the voltage at the expense of a lower overall vcore (minimizes drop). OCP increases the current limit through the mosfets to the cpu.

Oki i think 2.08V with a R404a mach II and my mobile cpu is fine ;)

I tried the vcore mod but it wasn't stable, I think i will try the vdrop.

Thx SAE, you see Nventiv will be repurchased, that's cool for us :D

I hope so... just a guess from yours??? :)

It's not sure but here we talk about and that seems to be serious.

What APIC got to do with stability?...is it really make system more stable to OC when APIC off...
what to loose for the system if APIC is off all the time?...

APIC decreases 3D performance... it gives more stability with high vcore at high fsb, with raid cards/SATA... USB, sound...

Yep, was using 8rdavcore version 0.8.7.

WOuld like to find the AGP bus latency in WPCREDIT so I can do it automatically on startup. I know the AGP controller latency is bus#2dev#0Func#0 offset 0D.

I backed off it though, to default and still stable, so I dont really need it.

I need to research the "6,5,6,3,3,5,6" to find WHICH one(s) were responsible for the boost.... could be very valuable information for Oskar, in tracking down high FSB agp stability.

For cooling, I like the idea of dimm1 and dimm3 better than 2,3. An added bonus.

Anyone know how to set MBM5 up properly for the DFI? seems to not be quite there.

Yep uwackme, good job.
With my TI4200, I'm always not stable in 3D, the max I can do is the 6 first test in 3dm2k1... I can't pass an entire bench...

Fsb 250Mhz, Vdimm 3.3V, prime for hours, memtest and co are ok, latest bios from DFI (19/6)

I'd like to know how set the extra timings, cause I think they are responsible for the 3D stability, but I'm not able to find the correct timings.

Hope it will be better with my new hercules 9700pro...

wait.. u mean when u disable APIC it decreases 3D performance, right?

I think what he means that when APIC on...3D performance decrease...but it increases stability with high vcore at high fsb, with raid cards/SATA... USB, sound...

and with APIC off its vice versa....right...CMIIW
:D

No! It's the other way around...

APIC on is fastest but less stable with all peripherals... but APIC enabled gives you a nice boost in 3D performance.

can someone clear me up on what wpcredit tweaks u guys were talking about on page 7. are there any good ones I can try that could help out my overclock?

I think we were discussing AGP controller latency and AGP bus latency...8rdacore can diddle them..and the bios can diddle one, we were just talking about finding out what the address was for the other.

SAE: what bios are you using? is it safe to flash bios using thumbdrive? hehehe used the out of the box bios and i got to 257FSB 1:1 whats the highest FSB you have seen? thanks for your help

I am using the 5-5 modded by EvilouS atm... I am testing but I have no clue what 's the best one. I am actually sure that everything with the 1-31 romsip is no good for me.

highest stable fsb I have seen is around 260, you never would have a stable 265 or more because of the limitations of the board/chipset... :(

Nice fsb BTW :D

SAE: thanks for the info amma try it too :) any / commands after the awdflash.exe thing? thanks

what's the difference between 1-21 and 5-5 Evilous?...

I think 1-31 is no good for me either...always gave instability on FSB 250 using 11-2-2-2-2-9-12...I have to do 11-2-2-2-2-13-15 to make it stable on 3,3v with KHX BH5.

But I haven't try the 1-21 yet :D

Does FSB 265 is save?...will it kill the NB or the mobo???

I always use Winflash. I had to look up the commands in the file... There are more "timid" ;) users only using awdflash here, ain't it?? :D

You can also try the the Alt-F2 bootup flash... just load bios defaults, then put a floppy with the most recent awdflash.exe and the bios file into your floppy and restart. Immediately press Alt+F2 several times till it starts to read the floppy disk. The flashing procedure should begin.

EvilouS' bios allows higher fsb clocks due to better APIC optimizations that followed the 1-21... but it's way more risky to flash any bios newer than the 1-31 (4-29, 5-5), but there are also the new 6-1 and 6-19 to try (6-1 has the 1-31 RS). These should have less cold boot/warm boot issues and allow you to clear cmos without facing a no boot scenario... ;) (4-29, 5-5 did not load acceptable timings for bh-5 modules as default, 4th LED was lit)

Any fsb is safe as long as it's stable and you don't pump 50% higher voltages/currents in your board ;)

what points on the infinity can i test for actual vcore voltage with a multimeter? also, 2.1v is the most i want....what would be the fixed resistor value for that?

do i have to do the vsense thing if i just want 2.05 to 2.1v?

I managed to get 2.15v stable with a vmod on my Infinity without a vsense mod, but do not take that as Gospel as any hardened DFI abuser will tell you that everysingle board has a personality of its own. I'm not fobbing you off, but you would be best off finding out for yourself what is best for your board and I'm sure others will agree with me.

p.s. I didn't measure the resistance of my vmod at 2.15v as that would have required de-soldering the mod.

You can get that stable maybe... but you mustn't have a high fsb at the same time (>245MHz).

Dunno bout the measure points for vcore, unfortunately. But iirc it could be read at the leg of the toroid you connect the vdroop mod to... rightmost choke, upper leg. But I am not 100% sure.
