And at what resistance does the vdimm begin to increase? I begun at 200K and slowly dropped to 40K. There was no increase in vdimm. Or could it be my mod isn't properly attached?

About Vcore mod:

Vsense does nothing yet... noone was able to figure out how DFI got it to work and how to get around. But maybe the vdrop and the OCP mods would gain you something. Then you also could try to set the vcore to 1.825V in bios, then upping the voltage to 2.06V or so using the pot (pin7).

About the Vdimm:

It seems to be not connected. I get 3.55V at around 100K. Maybe you attached the wire to the wrong side of the resistor? (should be left side of the resistor looking from the IDE connectors)

OK thanks a bunch :thumbsup: You probably saved me from killing my board
:D

Thank god, not me :lol: ;)

I'll really thank God because my vdimm mod was ok but I was measuring on the wrong mosfet. I measuring my 3.3V line (mosfet at the end of the agp).
God knows how many volts I've feeded my RAM. But all is ok now and I can reach 266FSB. Not what I expected but I still have many biosses and bios settings (especially RAM settings) to try out.

whats the one located above the cmos battery then? it never moves from 3.36v?

LOL

I can bench up to 268 relatively stable... but everything above that is crappy

Too much vdimm seems to worsen things.

The right mosfet is the left one of the three located below the ram slots. you have to measure the back of it (the plate thingy) pointing north when looking at the board in case :)

Yeah, DFI always have a day form too, you'll probably notice. ;)
And the timings are very time consuming to test...

Maybe that's supplying some 3.3V devices located in this area (maybe the SATA, and some other chips, realtek maybe)

did modding ur tc 550 bring up ur 3.3v line on ur infinity or lp?

and is the mod pretty easy?

I modded each line, so the rails go up when I want them to ;)

It's quite easy, but not for unexperienced people.

Link's here: http://www.xtremesystems.org/forums/...threadid=31931


You have to experiment with the rails what's best for ya.

Best of luck, SAE :cool:

SAE,

are u cooling your vcore mosfets at all? i am not currently, but the side case fans blow right over them....i dont have them set too high coz of noise of course. if u do, did it help stablize ur voltages at all? dammit i want my toaster sig before its too late...lol

Yeah, I cool all mosfets as good as possible. Gained me stability :)

That's my current board...

SAE, let me know when u wanna sell that board. ;)

i 2nd that Mr.Hamster.....hehe

:lol:

As soon I can afford an A64 S939 ;)

/edit.

In case I don't kill it till then :D

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.

Can You show Us screen with prime and Mbm min/max (every 1s probe) with this 2,15V ??

Sae, the black wire is the vdroop right? Thats pin 10 to the back of the coil? No pots involved? Still haven't seen any good pics of the mod.

Don't you think you want a lil too much?? ;)

He already sold his hardware cause he has to concentrate on business primarily from now on :D

Yeah, right. I used a fixed 4.75k resistor. It's right where the hotglue is, soldered to pin7. The hotglue holds the resistor and wire to the board.

hehe I don't think so ...
It may by screen with prime and some kind of monitoring software :D
He should have one ...

SAE is giving new meaning to the term 'burn in':D

Hehe. Don't be this mean ;)

You can comment on my next dead board when it has ... just died :D

So:

vcore mod: pin7 - 50k var - ground
vsense mod: pin 10 - 50k var - ground
vdroop mod: pin7 - 4.75k fixed - back of toroid coil
ocp mod: replace resistors with higher value fixed ones

and only the vcore and vdroop are usefull. Correct me if I'm wrong.

You got it right... with the mods. But vdroop is pin7 to anything variable as well, so you could test for better results with other values... :) (I used 4.75k fixed)

And about the second statement of yours:

No, only the vsense is NOT nescessary, the other mods gain you something.

I'm sorry I cannot as like SAE said, I've sold that hardware off now as I do not have the time to mess around overclocking like I used to. Is there anything I can help you with, or were you trying to make a point about something?

P.s the only monitoring software I ever used was the Bios, the Winbond monitor, Sandra and my multimeter.

He wanted a proof ;)

No trust here... :D
