If I wanted to measure vDIMM with a multimeter, where would I place the positive and negative?
Do both the positive and negative go on the leg, or does negative go to ground?
Is that VCore Droop mod?

1 pin to mosfet 1pin to ground.

Theres no droop.
That is the vCore mod for adjusting vCore

vDIMM not required IMO, BIOS allows way too many volts for dimms to handle. Only thing is the choices are in 0.05v steps, so if you want better resolution then find a mod. I dont.

To measure vCore, as per my screenshots above you measure the choke(coil) leg closest to CPU socket. Best place is on the rear side of the mobo where the leg protrudes thru the mobo.

To measure voltages, stick your red probe on the item to measure, and the black probe on a ground (i like to use the black female in a molex). Set DMM to measure DC.

Thank you!

What about measuring OHM?

I am now aware that there is no VDroop, but there is VCore droop, correct?
Is there an available mod to fix that?

According to Everest, 1.26125 in BIOs is 1.22v WCG on all 4 cores load.

Muffin whats the CPUZ difference between Idle and load on it when all 4 cores are at 100% ?

BIOs set - 1.26125v
Idle - 1.232v
Load - 1.216v

0.016v difference.

[Millyons]

thats the DQ6 right? so the difference is the same as on the DS3P, Exacly the same, i would really be interested in the vdroop mod for it cause there goes my idea about changing the DS3P for the DQ6

ps try it with prime small fft and 1.4v in bios for a bit, the vdroop might be even bigger, usualy on this its the same 0.016v of difference, but after a while of prime and specialy with a little higher vcore and small fft the difference becomes 0.032

At 266x9 with a Q6600 (stock) giving the CPU 1.425v results in 1.392v both idle and load.
No vDroop.

hmmm nice Thanks! so i might change for it after all , what about when OCed to 3.2 or 3.6 at that voltage....

Give me about an hour for the sun to set and for the temperature outside to drop from around 80f to 60f, which greatly effects my room temperature.

I will edit this post with results.
It will be 400x9, 3.6GHz.

EDIT:
400x9 = 3.6GHz
1.425v BIOs
1.392v idle
1.376v load

0.016v difference.

To stay on topic, I have to apologize for my noobness.
I kept thinking that the lower REAL voltage was because of "droop".
This is incorrect.
I thought the BIOs was 100% accurate, but I guess not.
I learned that what you set in BIOs, you receive a bit less, and I thought that was a mod-able droop.
Just add more to get more.

I learned something. Sorry about my noob questions.

[T_M]

THERE IS NO DROOP ON THIS DQ6!
Get your DMM and measure it!
Software reported voltage is always going to give a lower than actual voltage btw

Droop is the difference between idle and load voltage.
Drop is the difference between set voltage and real voltage. Drop is usually not an issue since you can just adjust higher to get the desired volts.

T_M does your NB heatsink get hot? I have the Rev1.0 board, so I've got the giant passive heatsink, and around the NB it only feels warm. On an old DS3 I had the thing was scorching. Worries me slightly that I may have a bad application of paste. But I seriously don't feel like taking everything apart. After finally getting everything in my case setup exactly how I want, the last thing I want to do is literally undo everything.

I don't know if Everest's monitor is correct... it constantly tells me my motherboard temp (NB?) is a few degrees C cooler than my core temps. As in 28C idle when my cores are 32C idle and it reached 50C under load when the cores hit the upper 50s.

Though ET5 reports the "system" temp constantly in the 30C-35C range, so I don't know what the hell is being measured.

[K404]

I took off the heatpipe assembly on my DS4, replaced the stock "TIM" with Ceramique and the NB sink is still only slightly warm, and thats on a bad day.

Dont worry about it

[T_M]

I totally removed the HSF system, and replced teh NB with a very basic passive copper HS, and SB with a tiny passive Alu HS.
My NB does get hot, but mostly because im running +0.35V plus a bit due to my volt mod.

[Millyons]

cmon, T_M can you figure out a vdroop mod just for the hell of it, ok that DQ6 doesnt have it but it will help up with the DS*

[Nosfer@tu]

Does the DQ6 alos lack alot of the capasitors in the socket ?
There is only 4 One in each corner on the GA-P35-DS4.
They are not polar as far as I know, but can I use any type I want there?
That should be posible.
I know the best thing is to use the same smd condensators, but I cant read uF with my current monacor DMT-2560

Did Vcore, Vmch and Vfsb the this weekend.



Click the pictures to see full screen images.

Shows, Vfsb, Vmch and I added Vdimm readout for the fun of it. Vcore readout is placed at the missing Coils around the Cpu socket.

Again an overview shot, I only soldered the Vcore readout and used 2 whires to make sure he can read Vcore on one of them, couldent attach whires to the back of the coils sorrounding the cpu s0ket Very hard to make them stick

Overall View of the 3 Vmods and 4 readouts..

Just an image of the Grounding for the, Vcore, Vfsb and Vmch mods.

just measured my vcore on that spot and i get only 1.00v while cpuz is showing 1.232 and the quad is running spuper stable at 3200mhz, so im pretty sure that is something wrong, cant be 1v .... oh and the dmm is fine

[DMH]

One question does the same vmods apply to the P35-DS4??

[andre X_X]

does this mod works on P35 DS3P ??

Im not sure my Vcore readouts are correct. I just had problems mounting on the back side of the coils, I will check with my m8 I made it for.

One question does the same vmods apply to the P35-DS4??

yes the mods and pics I showed are done on the P35-DS4 So YES

does this mod works on P35 DS3P ??

Compare the DS3P and DS4 layout and if it is the same you are golden.

It is al about how the layout around the different chips is, if the chips are the same and the layout is the same you shouldent have any problems m8 ;O)

[Millyons]

DS3P is exact as DS4, its just missing the heatpipes, nothing else

[andre X_X]

glad to hear that... thx

[T_M]

measure vcore from the coil leg closest to the socket

[T_M]

I know its hardly worth mentioning, but the P35T-DQ6 also has the same vCore mod, and is required if you want to run more than ~1.85V due to OVP at bootup, but you can turn up volts after boot.

vCore mod GA-P35T-DQ6

[quintus]

any pll mods pls!!!

[darken]

€: I can confirm this board has no Vdroop! the 12 Phases works realy fine

Right... but the P35-DS3P has a lot! almost 0.06V and share the same PCB, but I didn't find the vdroop mod for it. could anyone help me?

thanks
