Measure the voltages on pin8 of the RT9214 ICs. Also, a pic of the front of the card would be useful.
Don't know which one is pin 8 so did this 4

Don't have a digicam so can't take any pics of my own card but this is a pic from the front from annother one

Hi,
Is there the same code 'RT9214'-code in both chips ?
I wonder those are regulators by richtek, and 'interesting node' should be #6. (BTW, In RT9214 regulator there should 0.6 V in that node..)
http://www.richtek.com/Product/Docs/DS9214-06.pdf
I marked those pins with yellow in figure below. The output voltages are found most likely in some of the points you marked, I think the nodes marked with purple below are Vmem and Vcore (?).
Modding of RT9214-regulator is quite simple: connect high value e.g. 50 kohms variable resistor between a 'yellow' node (=FB, pin #6 in datasheet) and GND. Lower resistance = higher output voltage. E.g. green nodes are GND, but GND can be found also several other places in card.
Oke thanks man
I will try it asap

Mods and measure points are as SikaRippa suggested
Oke thanks. But does it has to be 50K VR. Atm I only have 10k and 20k pots in stock

Did the VDDR mod with 20K VR and it works fine
Only the result is less
Without Vmod: 1180
With Vmod: 1220
Maybe some other cooling will work.
Vgpu mod comming up, just as pics

Here a some pics of Vmod for now. VDDR Measure point did stick very good so isn't on now.
Sorry for bad quality. Is with webcam.

Man you got me scared, why are you using wires this thick on that pot???
I understand the mesure pts but dude, be careful!
Suma.
O lol. I did use the hole wire
Only some little lines of the hole wire
And what does it matter how thick the wires are. The thicker, the better i think?

For the ones how want to, some pics of the Vcore Mod too:
