?? Vmods for ASUS P4P800-X ??

[Kjaups]

Have someone with good quality pictures with these Vmods (Vdimm, Vagp, and mayby for chipset too ).
I hope someone can write a little story too, what resistors used etc.

I have read, that the P4P800 Vmods works on P4P800-X too, but i havent find any good quality pictures

[persivore]

If the layout of the board is similar to the P4P800, the mods should work fine. There are Vdimm and Vdroop mods for the P4P800 over at Malves Corner. On the Asus P4 boards, the chipset voltage (Vdd) is usually connected directly to the Vcore supply.

(y)
Thanx, the P4P800 Vdimm picture was very nice

Now, can i use the P4C800 Vagp mod on my P4P800-X, because my chip code is LM324 but i dont have that IC in the end??? And ise ok to use only 50k on that?

Sorry for bad gramma and words, im estonian

The Vagp mod for the P4P800 is the same as the mod for the P4C800, but the LM324 voltage regulator is in a different place on the board. Its ok to use a 50k varaiable resistor for the Vagp mod

[Kjaups]

well, this is realy great


Now, the last one . Is there any vmod for chipset?



PS! How to you know, how/where u need to too vmod correctli (if its new and there isnt any mods in internet)? To you start to measuring everi mosfet and these litle chip or how? I just wanna know

[Kjaups]

Well, i managed to get some pictures of my mb and can you show my where i need to put the resistor and where i can measure later the voltage??? Near the AGP and Near the CPU and RAM.

same mobo as me AND same hsf as me :p

[Kjaups]

Help :S

[<Wouter>]

The vagp is prolly the same as the p4c800 vagp mod. Could you measure the resistance between pin6 and pin11 of the LM324 ic? Could you also measure the voltages on the pins i've marked?

And persivore, those guides @ malves use a totaly different board lay-out.
I think that the ic that i marked red regulates the vdimm and the ic that i marked blue can be used for the vdroop.

[Kjaups]

here u are

[persivore]

Can you check the voltages at the points that I've marked please, and check that the chip is an LM324.

Edit: Can you also check what is written on the top of the chip I've circled in the other picture please.

[Kjaups]

well, here it is

the other picture :

HIP6302CB
P501CQ7

[Kjaups]

new test.

the core is set to 1,45v and mem is @ 2,658v

[persivore]

Can you check the resistance between the pin I've marked and ground. I think that pin should be controling Vagp. Check resistance with the power off.
I'll keep looking at the Vdimm mod

the resistance was with 20k @ 1,19 and witn 2k it showd only ,997

are these good

[persivore]

For the Vagp mod, try connecting a 50k variable resistor between the pin that you checked the resistance at and ground. Decrease resistance to increase voltage. You should be able to check Vagp at the MOSFET with one pin reading 1.56v in the picture .

There isn't anything obvious for the Vdimm mod on the voltage readings there. What is written on the 8 pin chip near the ATX connector?

well, i cannot be 100% sure that i readed that writed txt out exactly, because thta txt was so gd tiny :S

** - couldnt read out at all, mayby somekind of symbols :S

That doesn't look like its a voltage regulator

[Kjaups]

deem, its sad to hear :-S .

[EDIT] MAyby something still can too
Someone cold come out with great plan

[Kjaups]

I made the Vagp mod and i think it is affecting the nb too, because i set 1,59v @ 1,643v and now i am with FSB253 in the internet but without the vmod i had FSB253 in bios and booting up windows, my PC crashed.

Thanks guys , i go to test now for some more

[<Wouter>]

Nice!

[lawrywild]

have you done vdroop on it yet??

[Kjaups]

have you done vdroop on it yet??

no . should i too it it probably takes too much time

[lawrywild]

lol it's really useful though...

[Kjaups]

hi guys, need help again. how i can to this vdroop, i realised that i need it. @FSP253 the voltage droop down from 1,582v to 1,474v in load with PRIME95 and when the low voltage comse, prime95 give eroor.
