Sorry I didn’t reply to this earlier but my XS notifications have been patchy if at all recently. No Resistance to ground, no Continuity to pin 9.

wich is the vgpu mod??
:shrug:
This one http://www.xtremesystems.org/forums/...7&postcount=41
50 ohm pot between pin 9 & ground
CN :)
but this guy use a pair of 500ohm!!:shrug:1mohm?
o 50ohm??
but this is for one core or 2 core ??
sorry
spl
use any vr from 50ohm to 500ohm the lower '50ohm' the better as you can tune in better since stock resistance is 3ohms or so
and btw if you join any two legs of the ic you can short the card even if the power is off if power is left charged in the caps
so if you have a great card/s and cant rma or afford to kill a card at '$559' the odds of this mod going wrong are very very high
:)
yes there are TWO gpus each needs its own voltage mod
gpu #2 towards the back of the card has a solder pad that conects to pIN#9 on the back of the card easy access easy soldering
gpu#1 has no solder pad so you have to solder directly to the leg of the vreg pin #9
you can use a 20ohm to a 1k vr, lol but anyhting over 50ohm is asking for trouble some guys use what they have casue well thats all they have/had at the time
so 2 mod
for 2 gpus
and use 2 50ohms multi turn vr's :)
CCC can you please give me a resistance value (measured on the vr after you disconnect it from the circuit) to use as an estimate, as I use fixed resistors - I avoid vrs at all costs.
spl, sounds like you havent done enough research to be attempting a voltmod on an expensive card.
might i suggest you learn about common volt mods before ruining your 4870x2
:doh: Great suggestion.
any air results?....the card goes 860 stock for me now..
not too well 31500 o5 stock clocks and about 90k 03 840/1000
now i put e8600 back in,and i sent card back to newegg for refund.
First card modded, bought a new superfine tip for my iron just for this :banana::banana::banana::banana::banana:.
My default resistance was 3.1 Ohms so i used 100 Ohm VRs.

And now to test it :D

Great suxses!
Now for the second card.....
Damn...that takes balls Tim, I didn't expect anyone to actually try soldering right to the IC leg. :eek: I was planning on gooping the whole area with glue gun and praying for the best myself. :p:
Has anyone thought of exposing and connecting to the trace on the PCB that comes from that IC leg?
nice work TM>
both my cards are also now soldered. all ya need is a steady hand a good iron and good light and its not that hard at all :)
nice work :up:
The hardest step is to get a small dob of solder onto that IC leg and draw it out to give something a bit nicer to connect the wire to.
After that yeah a piece of cake.
Here's one modded card rekitted for hardcore air testing:

emertX, those clocks speeds are possible by flashing to the Asus TOP bios (see other thread).
You can manage the fans/clock in a variety of ways, BIOS / CCC / Rivatuner / AMDGPUClockTool / etc.
Thank you!
Is it enough to flash the original asus top bios? Or do I have to flash yours?
