Gigabyte DS3 Vdroop mod

[//\\//3W]

I reached 3.6ghz but it isn't stable.

Did you guys use pencil on this mod?

I have a rev 1, c1 chipset board and this mod didnt do anything with a pencil.

I tried as shown here -


Has anyone had luck pencil modding this on a rev 1 board?

Like my post above. The mod seems to have hit and miss.

EDIT: Tomorrow for definite, I'm getting a proper silver pen for this. I still have a rev 1.

mod worked for me on rev1 c1 ds3. used copper ink from rear window defrost repair kit

So the location is correct, apparently a pencil won't do it?

Was it stable for you? I see some people had issues after this mod.

Unfortunately I don't have that ds3 anymore, but yeah, I don't think you can reduce resistance to 0 with a pencil. I didn't have any noticable issues after the mod, and indeed vdroop was gone

I didnt get anything from using the same #2 pencil I (successfully) pencil modded my P5B-Deluxe with. No affect on droop at all....

Are we sure about the mod I posted above and the locations? This one is completely different. So I highlighted in 2 other colors possible locations. I tried the first (yellow one) with no change in droop at all, which tells me that isnt the right location. Or is it possible you are supposed to pencil across the (green)?

[dnottis]

anyone?

I got the silver pen. www.bondloc.com Just that my Rev 1 DS3 rig is over in another house crunching away. Well its the one that has the biggest droop. I'll try it tomorrow. I MAY try it out on my main rig DS3 tonight here. But that'll be a lot of hassle. Would prefer to try it on my caseless cruncher.

Lemme know where you are gonna connect with that pen, and if it works...

I hate the droop on this DS3, but right now my p5b is acting screwy. I love the pencil vdroop mod but the p5b hates OCZs Reaper 1066 memory.

Finished. No change. Covered the green resister in silver conductive paint. Still droops.

The original mod was the yellow one

I did check them. I'll have a go at the yellow one tomorrow perhaps.

I'm gonna try the mod on my Rev 1 C1 S3 in a little bit. I didn't realize how horrible the vdrop is. Setting 1.425V = 1.344V idle 1.325V load. Also have the 1.6V bug, but it usually bugs out when setting 1.56 or higher (multimeter reads less than 1.46V, a full .1V vdrop.)

I can confirm that the vMCH and vDIMM mods work, 10K VR works fine. Can bring it up higher than 3V with only a 10K VR but have only tried up to 2.82V. Did 501mhz Cas 3 with 2.82 and 1.68V on the MCH. Don't put more than 1.74V on the northbridge or it won't post, it has OVP at 1.75V.

Where do you guys measure the Vcore from on the board? You have any pictures showing where?

[Lestat]

any of the copper coil backs around the cpu area will show you vcore and droop.
the pwm units will also. 1 leg will show way high voltage which is simply the input voltage of the PWM the other leg will show real vcore.

dont be surprised at all if you see a much different voltage than what the bios shows.

So like this.....



That correct?

Can anyone else confirm this?

Also Lestat, where is the VRM for Vcore??

[carey8]

ON the Rev3.3, the Vdropp is hardly anything anyway.

[cool_dude]

Lestat, could you confirm what I've done in the picture?

BTW, mines the first revision.... and carey8 how did you find this out?

[kuryu]

Here is a working Vdroop and consequently Vdrop mod for the GA965P DS3/S3 V3.3 motherboard.
Before this mod for me on my DS3:
1.5V in bios
1.47 Idle Everest
1.42 Load Everest

After mod
1.5V Bios
1.49 Idle Everest
1.49 Load Everest


Thanks for the layout picture RejZoR.

Good work, thank you.
Can anyone confirm that it works?

same question. I am still using the board with my Q6600 G0 at 3.6Ghz. That CPU would do far more and stable if the Vdroop weren't a drawback.

ok, done the mod using a bit of solder over the resistor and it works perfectly. i am now running prime stable @3.2Ghz using the stock voltage of 1.275V or 3.6 at 1.38V
