I would recommend using a 20k VR for the vGPU mod.

The VRAM is more damageable by higher voltages as a GPU, so I would take the bigger VR or built in a switch.

Didn't notice that ^^
In fact it does not matter much, the GPU will run fine even with a slightly higher voltage. Just make sure you use a 50k VR for the vMEM mod.

Voltages needs to be measured while the card is running. Put the black wire of your DMM to any ground point and the red one to the voltage reading points(see pics).

Use two those: http://jaycar.com.au/productView.asp...k&form=KEYWORD

They are both multiturn VRs but the second has got 25 turns and will allow more precise voltage adjustements.

update D:

gotta wait either 2 - 3 days ( if in the city.. melbourne )
or about a week if in their other wharehouse >.< other side of the country..

but i orded 4.. so could attack another card xD might solder on wires ect ready to go though.. see how that goes :S will either be later tonight ( like 5 - 6 hours ) or 2morro xD

thinking about cooling what should i do?

A.
* these faily large heatsinks not ment to be used on vram. their like 5cm tall give or take.. lol ( wuld they work? :/ )
* + universal waterblock
their to big dw

B.
* normal vram heatsinks
* + universal waterblock

C
* accerlo s1 v2
* normal vram heatsinks

all will be paired with a 3k rpm fan ( for vrams. ) and if wc most likley a slush bucket O.O cause im cheap like that.. haha

the air cooling is like $35.
water block alone is $60 >.<

proably wouldnt use the waterblock again unless benching.
might use the air cooling one on 460 l8r.. ( 70 folding >.< gets a little hot with stock cooler )

If the waterblock is really universal I would contemplate buying it. But this means it should really work with all kinds of mounting hole distances.

The ACS1 will fit on many cards but not all, espacially not older ones.
