bump, need answers if i can use a 10k and if it is between the pins i wrote
The Vdd mod is between pins 5 and ground. It would be best to use a 20k VR so that you don't put too much voltage into the mem when it is at maximum resistance.
okey but if i use a 10k set at exactly 10k i would start with 2.2v right? that is if the vdd is 2.1 standard, i only have a 10k here now so im hoping it will work as im gonna do the vdd mod later today or tomorrowQuote:

ust have 1 10k, well i found right on elfa now so im gonna order the right ones, first i only found some that cost 8dollar each but now i found the right with half the priceQuote:

Replied to the PM snowman.
It should work, but just take the voltage up slowly. Pencil mods can be a bit unpredictable sometimes.
i am going to do the mod once i get my chiller finished up hopefully next week...i also am ordering a 3500 clawhammer as my 3000 winnie sh*t the bed... :( the X700 is going to be cooled with the chilled water hopefully i will have an X850XT PE killer (hey i can hope!!! DONT BURST MY BUBBLE!! lol jp...)...but it shoul be pretty fast as right now mine is on par with a x800pro at stock...so not to shabby...btw i am making the block "almost" like the nv-68 as i have 128 ram so it is only on the front i will post pics and so on...
BTW what are some safe voltages for below -20 deg? i am hopping i will be running around -40 but -20 at the least so what are some safe mem and core voltages?
I would say even at -20/-40C dont take it above 1.7, the 0.13 chips just cant handle much more than that at any temperature. Ram i wouldnt go much over .25 above stock. These are if you are planning to keep the card, if you just want to bench it then toss it, i would say cranke em up :D

I thought that the X700 like the X800XL used .11nm? And temps that low you can only go that high with volts?!?...hmm ok...does any one else have any input (not saying you are wrong by ANY means...that just seems like a VERY small bump...)BTW the card is only untile i get an x800xt or until the Fudos come out...

they are .11. And I wouldnt go above 1.8v for daily, maybe 1.85 since you have good cooling. But wtf do I kno, never played with a x700pro so Im just guessing.
Usually, you'll "feel" the limit.
If you increase the vgpu slowly and run tests in between all the time. When there is almost no gain at all, that's the limit. But I'm not saying that you can run on this limit for ever, but it's definitly not any point in running higher than that what so ever.
There is no general rule for max voltages, not even for the same chip. Some chips clocks diffrently than other with the same voltage.
did it yesterday, lowered resistans by 40 ohm, got 0.4 LOWER voltage :confused: AND higher overclocks wtf is going on here :slap: :confused:Quote:

sorry, typo, 0.04v :DQuote:

Anybody have some nice pics of completed mods?

pics coming up

Here is a pic of my vgpu mod.. its at 1.56volts right now. i used a 50k ohm pot on it.

Looks good Maxxx. :up: Only thing that concerns me a little are those long wire leads. Specially the yellow wire, where it looks like the wire lead is about to touch the resistor right next to the where you soldered it.
Malves theres no resitor next to it.. its blank.. so no need to worty about it.. heh. made sure of that..
the blue wire ill prolly change as it is uselessly long. i made the wire lenghts before i hooked it up to the board.
Hey guys.
Did the Vgpu mod and gained from 490 (1.36v) to 550 (1.68v)
But havent seen anyone with the vdd mod.
I`m stuck @ 600 for the mem right now.
So wondering if it would help any.
Thx in advance.
/EQ
wel i got form about 500 to 550 with just 0.1 extra volt on vdd and vddq
will add more later but STILL working on getting my watercooling installed (well its more a casemod then just adding watercooling)
Kewl.. I can do 495+ in 3DMark05 without any mods. I hate that my Abit 256mb card doesn't look like the other cards :dammit:Quote:
