Well I have decided to volt-mod my video card. Now, this is my first time and i have broken the card twice. Lucky for me i've been able to fix it both times. when i broke off a resistor i just about crapped my pants lol. Newayz, i just put another one in parallel w/ the potentiometer. But anywayz, its running great right now. I haven't actually adjusted the voltage yet cuz i still only have stock cooling on it. my ATI Silencer4 is waiting for me to do the VDD mod and the VDDQ mod which will be done later this week. I just thought i would post how its going so far. I know it doesnt look professional but it works great so far cuz its running right now

I used hot glue to protect the solder joints and keep them from breaking off or anything. probably not really necessary but i like the extra security. especially since i seem to keep breaking it lol. Its a learning experience (an expensive one haha). So, what do yall think? (at least try and be nice

)
*edit* i just noticed its not the best picture but im sure u get the point. lol

nice job.
When you get your cooling on you have to post some overclocks.

*UPDATE*
Well, ive done the VDIMM and VDDQ mods. I just dont know how far i can crank them up. ne ideas? I'm gonna post a pic below... For those who think the leads are too long, its really not a problem. Some ppl say it can create 'noise' or 'distortion' but thats just due to electric fields and the easy way to fix that is by twisting the two leads. Basically, since the current in each wire is going in the opposite direction, the fields oppose each other and cancel each other out. You can confirm this w/ the 'right hand rule' if you want. But anywayz, i havent had any problems with it. its running great right now and i'm hopeing that by the end of the week, i'll have the voltages set and the ati silencer4 back on so i can do some overclocking

I would hot glue the VRs to the card, but is your card.
voltages
1.5-1.6 core
2.2-2.3 I have to do more reseach on memory voltage
I run my x850xt at 1.7, but that is with very powerful aircooling.
Just check your core temps, I do not let mine get over 50*C, but that is just me. They can take 70*C+ without frying.

they have issues fitting on there w/ my cooler so i'm actually gonna mount them on the cooler. it should look OK when im done. As for the voltages, is that w/ air or water? cuz im using my arctic silencer4

Tbone uses nothing but air for now, but it is xtreme air.
Be careful with the mem voltage. The core can take alot of adjustment, but the mem can be very sensitive to voltage hikes. You need to have really good cooling to pass alot of voltage thru them.
Good Luck!

The voltages above are with normal air, like yours.
Mine is with air, but not normal air. I have a lot of fans on my card. So far I'm at 700core. What were you doing before your voltmod with overclocks?

before the volt mod, i'm getting (547/581) i think. Not miraculous, but whatever lol. it did 14002 in 3DMark03. i dont have crazy cooling or anything. just a bunch of extra sinks on the back of the card to help w/ cooling, plus i have a 92mm fan blowing across the card. Here are some pics:
This is the back of the ATI Silencer w/ the extra heatsinks. I was trying to help dissipate the heat on the RAM.

This is the 92mm fan i ghetto rigged so it blows across the video card. mainly the top of it but it also feeds some air down to the intake on the card. its not pulling fresh air from outside but at least its moving air haha.

haha your cooler. It bet it helps a little by glueing heatinks on a heatsink, but it looks funny. Does your heatsink cover the memory too?

the front has active cooling cuz it covers the gpu and ram... the back has that big metal plate for passive cooling, but even it gets really hot so i put all the heatsinks on it lol. plus the ramsinks right on the back of where the ram makes contact. w/ the 92mm fan blowing accross it, it should help keep it cool. the air should then flow up(ish) and out of the back through the 120mm.
*edit* i figure the more surface area there is, the better the heat w/ be dissipated. (hence the extra heat sinks)
