ATI 5750/5770 voltmod thread

[ceemic]

I'm not an electrician, but afaik caps shouldn't never put to a long wire.

[Radamanthys]

Woow , what clocks can you manage with the cap mod ?

[Theorw]

I'm not an electrician, but afaik caps shouldn't never put to a long wire.

I ASKED AN EXPERIENCED MODDER ABOUT THIS
and he said there is no problem!!

[ceemic]

Theorw, ok then

[Riska]

When you do this mod with wires it dosent work nearly as god as witout because the caps have to be as close to the solder point as possible to work proberly.
The thing on this card that neds caps are the memchips i will do a full mod on one of my cards soon to try if there is any affect

[Riska]

trust me wires are no go i have cap modded cards for over 8years and wires dosent help and i mod psus and hifi and carstereo and trust me wires are no go.. the thing a cap does is to provide current lightning fast to the circut and with wires the current mett alot of resistance and the effect goes away

[Riska]

Look what i did with a HD3870 card..

@RISKA
It makes sense what u say about the resistance of the wires...maybe i should put them on the top of the other caps or could i leave 1 CM of wire???Say the CPA had REALLY long legs????????

[pr@$r1g]

can any one tell proper voltmod for 5770 (GPU & MEM)

1120 1.32 Easy passed all 3dmarks
1140 1.35 passed 05 and Am3

nice scores, how high would you suggest on voltages on air ?

I have an XFX flashed to asus

[hiwa]

1.32 Stock fan100% 1060

[Assassin48]

1.32 Stock fan100% 1060

sweet thanks

i was able to do this on less then 1.25 i think that was the highest with 100% fan speed

So the core did scale nicely under cold hiwa? in a week or so im putting it under dry ice, due to the lack of a dewar atm.
you think your vmod was more stable then the softmod? or why did you mod it..

[hiwa]

scale 60MHz air to chilled water 15°c with same vcore
i think subzero u can go over 1200 without problem

i never used softmod if i can hard mod it

[pr@$r1g]

can any differ
what is pencilmod ?????
&
what is vmod ?????
Im confused :s
Never done it but will do with this card ,when it arrives

[thijs]

btw hiwa, saw your 06 scores and such, and i was wondering why you have 1300 mem? i get like 21.4k with 1470 mem, and with 1300 mem around 800 / 900 points less, cant amagine my memory is different then yours?

U mean u left the stock volts and just soldered the resistor right?
So what resistor did use 100k?Was it easy?

[Riska]

a 50khom vr is fine and it will give a boost to vgpu around 0.050-0.075 v at stock

[Theorw]

I measured the resistor.turned out 2,1*k so i used 100k that i had in handy.Turned out it worked and the volts were really stable in comparison with the volts the chip would output...Too bad the cable broke off and for a moment my card would reboot and i thought it was dead1!!
Tomorrow i am gonna put it back on and see what i can get!!!

it's core freq and win7 SM3 on win7 is faster than vista or xp,btw becareful with over 1300 mem freq,Hynix can handle max 1250 on air and def voltage.

as riska says 50k is ok 2015ohm measured

[ceemic]

Theorw, did I get it wrong or You turned 100k VR to 2,1k before soldering?

thanks for the tip, you didnt bother with vmodding the memory?

[hiwa]

no i have just vgpu
with def mem voltage u can run over 1320 without problem, but it's risk on hynix
