Aegis Posted April 6, 2006 Share Posted April 6, 2006 An overclocked 7900GT can easily reach 7000+ 3DMarks in the 2006 edition:http://www.vr-zone.com/?i=3437&s=3Only problem is you have to unlock the voltage. It's suppose to be as easy as following these instructions:http://sg.vr-zone.com/?i=3330&s=2Now what I'm about to ask here might be a stupid question, but for those of us who have never taken a single electronics class, how do we even begin? How do you remove a resistor? How do you connect to ground? What's a 50K VR and how do you replace it? Link to comment Share on other sites More sharing options...
03GrandAmGT Posted April 6, 2006 Share Posted April 6, 2006 (edited) Aegis, Get a solder sucker/solder wick to remove solder/components. Becareful here as you don't want to damage the traces or pads. Get a grounding strap, a wristband that connects to a grounded workbench. 50K VR is a 50,000 ohm Variable resistor. You will also NEED a AVM Analog Volt Meter or a DVM Digital Volt Meter. That pencil stuff is fun. OC'd my athlons using that method.Replacement:1. Using the grounding strap connect to GROUNDED work bench. If you don't you can damage the components on the board. (Don't let the smoke out)2. You need a GOOD soldering iron and electronics solder.3. Solder sucker or use solder wick to remove the solder from the backside of the board (where the components legs stick out from backside of PC Board).4. Remove component, clean the solder holes real good with solder flux, soldering iron and solder wick. This will remove any stray solder from the holes.5. Put Variable resistor in and solder.6. Adjust VR according to their discussion.If you blow something up I am NOT RESPONSIBLE!!jd Edited April 6, 2006 by 03GrandAmGT Link to comment Share on other sites More sharing options...
ripken204 Posted April 6, 2006 Share Posted April 6, 2006 wtf is wrong with you! lolaegis, you know how bad your luck is with hardware, if you do this and screw up then your warrenty is voided... Link to comment Share on other sites More sharing options...
Scubar Posted April 6, 2006 Share Posted April 6, 2006 i would seriously advise ppl to not try these kind of modifications unless they are extremely good with a soldering iron and a pure power fanatic. its not like those cards are slow anyway.

Aegis Posted April 6, 2006 Author Share Posted April 6, 2006 (edited) Well I guess Ripken and ScubaSteve are right on this one...There's a likely chance I'll screw something up ...maybe burn myself with the soldering iron too. Really wanted that 30FPS increase too... Edited April 6, 2006 by Aegis Link to comment Share on other sites More sharing options...

Really wanted that 30FPS increase too...Aegis,Just get some SCRAP components, PCB and try it. After all you weren't born already making the Gamer's Edition. You had to learn programming. Hardware is no different really, just practice it. Or if you know someone close that has the abilities have him/her do it. WATCH-N-LEARN. Alot of people are scared soldering surface mount components, being a hardware field support person I don't have the luxury of all the neat soldering tools for surface mount components. I just use my standard Weller Bench soldering iron that I have had for as long as I have been with the company 12+ years. jd Link to comment Share on other sites More sharing options...

Clint Posted April 6, 2006 Share Posted April 6, 2006 If you are satisfied with 1.55volts you do not need to remove or solder anything, only dab some conductive paint on a couple of spots.That is easily removable and will not void your warranty.http://www.xtremesystems.org/forums/showthread.php?t=92874 Link to comment Share on other sites More sharing options...
Aegis Posted April 23, 2006 Author Share Posted April 23, 2006 I'm confused why I'm getting these strange results. At the core clock of 553MHz I'm hitting 9130 3DMarks, then if I up it to 554MHz I hit 8600. Can upping it one megahertz really lower your score 500 points? Or is this just standard deviation ? And then I tried increasing the clock to 567 and I hit 9160. Only 30 more points for an increase of 13MHz? Link to comment Share on other sites More sharing options...
gdogg Posted April 23, 2006 Share Posted April 23, 2006 (edited) core clocks, then put the vertex and pixel shaders on multiplers, some times a lower clock, will hit the right vertex/pixel shader unit overclockwhere a higher clock, will throw it on a lower multi, slowing down the vertex/ps.cant explain it any better, w/o finding my source.

RyanVM Posted May 1, 2006 Share Posted May 1, 2006 Why not just use a conductive pen to connect the points?http://forums.anandtech.com/messageview.as...hreadid=1847758 Link to comment Share on other sites More sharing options...
ripken204 Posted May 1, 2006 Share Posted May 1, 2006 ide volt mod it if u had the 7900gt, im lucky that nvidia didnt do that stupid thing to the 7800gt, i just modded my bios for some extra volts. Link to comment Share on other sites More sharing options...
