Vdroop mod request

[Gir92]

I know this is an odd request considering the motherboard, but I figure I'll go for it anyways.

My backup rig has an ECS G31T-M board, an E1200 and regular 800mhz G.Skill 2x1Gb RAM.

The board does not have any voltage controls through the bios, so I am planning on doing a VID mod on the processor with conductive ink here (http://sg.vr-zone.com/articles/Intel_Core_2_Duo_Voltage_Boost/3904-3.html). However, running stock volts, I get an insane vdroop of 0.04-0.05v

Is there any way to do a pencil vdroop mod for this board?

Also, the RAM volts are stuck at 1.81v, so I have to use low ram speeds to keep it stable. Is there any way to up the volts on my RAM since I can't do it through the bios?

Thank you. :)

take pics of the top and bottom of the cpu socket and top and bottom of the ram slots and post them I'll help you out.

I don't have a high quality camera, but I will try my best.

Pics coming soon.

Thanks! :)

Alright here you go. If you need better pictures that are focused on a smaller area of importance, I will gladly take more for you. I just tried to cover large general areas.

Can you confirm this board has the RT8802a chip?

Where would I look on the board to be able to tell you if it does or not?

This chip!

[Gir92]

Yep, it has

RT8802A

Written on it.

I will try to look into it tomorrow, and otherwise there are enough voltmod masters at XS :up:

Alright thank you, I appreciate the help. :)

[philbrown23]

well is there a pic of the top of the ram slots? or maybe on the frontside of them just above the 24pin connector? but I do have this, you'll need a volimeter and to check back but here:

Is all that there is around the RAM, nothing else.

And I will be glad to measure those points, but I need some help first. I only got a digital multimeter last week and am not completely sure on how to do everything on it. I managed to measure the vcore on my 7900 GT fine, but I'm clueless on anything else.

Can you tell me what to set everything to for the multimeter pictured below? I know to set the red pin on the spots you marked and put the black one at a ground point, but not anything else. Again, thank you for all the help you've given me.

Accidental double post?

turn it to the right at the 200ohm if it wont read out then try the 2k right above the 200 for vdroop, for vcore you can try 2k or 200k

[Gir92]

Hmm. The vcore reading went fine, fluctuating between 1.2 and 1.3v. But no matter which setting or point I use to measure the vdroop, it always shows as 1 and doesn't budge at all.

[philbrown23]

wait hols on. did you turn your pc off? you must turn it off to get the correct ohm readouts and you should turn your power supply switch off to. sorry, I forgot to mention that before.

[ceemic]

I suggest to remove all components also, including CPU!

For Vdroop: try to search where does pin #15 head to. Measure resistance between it and GND.

For Vcore: try to search where does pin #4 head to. Measure resistance between it and GND.

[Gir92]

Ok very noob moment, yes I had the PC on.

And you say measure resistance between a certain pin and grnd. I was using the ground on a molex connector as my ground, should I be using something else? If you could label the parts and have numbers pointing to them that would be awesome. Perhaps red lines and black pointing to where I need to connect to ground?

[ceemic]

Look the datasheet: http://pdf1.alldatasheet.com/datasheet-pdf/view/207883/RICHTEK/RT8802A.html
Now You know pin layout.
You can use molex GND, but I suggest some GND point near to socket area. ATX24 has several GND pins. You can use them...

[Gir92]

Alright for the vcore I'm still getting between 1.2-1.3, and for the vdroop points, I'm reading .04

[ceemic]

What 1.2-1.3? 1200-1300 ohm? ADJ->GND resistance is 400 ohm?
Have You find spots where the pins head to?
