Hard-modding Gallery

===========================
Hard-modding Gallery
===========================

I think this section is lacking something. I can see a lot of disscusion about cooling, but hard-modding is nowhere to be seen.

So maybe you guys have done something to your hardware....replacing capacitor, voltmods, replacing components.....then post it here and show us your leet soldering skill.

Just give us a brief description of what you've done and show us the pictures

So, let me be the first one to post (there'll be more coming )

This is my moded Antec PSU. All the voltage rails is now adjustable. The real true powah!!!!

Pushing your 9550GT to the limit!

hello there. after the psu mod HERE now i'm back with

-=||Gecube 9550GT voltmodding & bios modding guide||=-

first i will touch the voltmodding part and then the bios modding part for some mem timing tweaking. before we start, i would like to give credit to Dead_Man for the vgpu mod and Łukasz "OCMaster" Warszawa for the vmem mod. ok let start.

-=||vgpu & vmem||=-

front image of the card:

back image of the card:

10k pot for the vgpu and 20k pot for the vmem. both of this pot is connected to ground.

here's my finish mod. ignore the third pot. it is for the vddq mod but i find that increasing vddq introduce a lot of artifact. so i remove it from the guide.

after the mod i was able to get 590mhz stable at 1.66V on the core . but the mem wont fly even at higher voltage. so the next part is how to mod your bios to relax the timing to get a higher overclock.

-=||bios tweaking||=-

------------------------------------------------------------------------------------------------------------------------------------------
updates 16/01/2006: i found this site techPowerUp! which contains loads of ATI bios. so i start downloading other 9550 bioses and look through the different configs of the timings. after some testing, i found that abit 9550 bios to be the best interms of performance and overclockability. i was able to clock my mem to 290mhz(580mhz ddr) . for my guide below, u will experience some lower performance due the relax timings. so i suggest u use the abit bios.but i leave the guide below for references on how to mod a bios.

-------------------------------------------------------------------------------------------------------------------------------------------

ok now we are going to solve the problem with the lower clocking mem. the mem on my card is samsung ddr 4ns ram rated to run at a max of 500mhz. but during my oc, i only manage to get 460mhz artifact free and higher volt did not help to get any higher. but after the mod i was able to achive 520mhz artifact free . so here's what you need:

1. RaBiT-Radeon Bios Tuner
2. ati flash to flash your bios and to dump your bios image.
3. Ati Tray Tools or ATI Tool (easier way to dump your bios)

i'm currently using ati tray tools so the guide will use this.

first, dump your bios by right clicking ati tray tools-->tools & options-->dump video bios. name it something like default_bios.bin and keep this safe and unmodified. next using RaBiT open the bios that u have dump and go to the "MC Timings" tab. here's a screen of my default bios unmodified.

the timing in the redboxes is what we are interested in. don't touch the other settings especially the cas latency or you will end-up with weird graphics. so the changes that need to be made are:

1. tRcdRD from 3 to 5
2. tRcdWR from 2 to 3
3. tRP from 4 to 5
4. memRR from 18 to 20
5. tRFC from 15 to 20
6. tERST from CL-0.5 to CL+0
7. tQSREQ from CL-0.5 to CL+0

all of this changes is based on a Gecube 9600Pro card. Here's a screen shot after the mod.

ok after all the changes have been made, save the bios with different name like 9550_mod.bin. next we are going to flash the card with the modded bios.
create a bootable disk and copy all the content of the atiflash zip file into the bootable disk. now copy your moded bios and your default bios into the disk and boot your pc with the bootdisk. (side note: i use my thumbdrive as a bootable disk. less prone to error)

now at the command prompt type "aflash -p 0 biosname.bin" and wait for a few second for the bios to flash. when the command prompt appears, reboot your pc and hope nothings bad happen

-=||results & conclusion||=-

with the clock above i scored 4300+ in 3dmark03. the result should be higher if my mem can oc better. but 520mhz is already above its rated speed and already good enough for me to play nfsw with high settings

so for those brave souls that are willing to do the mods, good luck to you guys . if you got any questions, post them at The ATI 9550 Official Thread

happy modding and good luck,

[Guide]Mod for psu without vsense line

Shah81 — Sat, 22 Oct 2005 17:47:01 +0800

Introduction
By Shahrizal Shariff

A few months ago I've posted a guide on how I successfully mod my icute psu. After that I receive a lot of questions and the most common one is "My psu is xxxx (icute, aopen, cap ayam ...) how to mod? ". At that time I was busy with my industrial training, so many questions are not answered....sorry....

I've finished my study last month so have plenty of time to waste. Have 4 different psu here at home so I decided to write a more complete guide to mod psu without the vsense line.

Here are the psu that I have:

~Digituz model: ATX-400W/P4
~L&C Technology model: LC-250ATX
~Cap Ayam model: 300W psu
~iCute model: ATX-450W/P4

This guide is divide into:

1. 5v & 12v line mod
2. 3.3v line mod
3. applying the mod on iCute psu
4. Tips & Trick

Some Warnings and stuff you should now.

1. Its dangerous to play with electricity..you could shock or even kill yourself ...so be careful ( discharge your psu before opening it up)

2. This mod only increase the voltage output of your psu. It will not increase its wattage nor will it convert your psu into true power .

3. Yes...your psu might be damage by doing this mod and it may also blow up ...so stop posting messages like "I think you gonna blow your psu". I get a lot of this messages in my last post and it is very annoying

4. You will void your psu warranty so keep this in mind.

Enough with this now lets move on with the show...

1. 5v & 12v line mod.

Here are the list of psu and the IC that they use to control the 5v and 12v line. Please also note that both of the line will increase simultaneously together. There is no way of modding only a single line either 5v or 12v.

~Digituz model: ATX-400W/P4=======>IC: TL 494 CN
~L&C Technology model: LC-250ATX===>IC: DBL 494
~Cap Ayam model: 300W psu========>IC: KA 7500 B
~iCute model: ATX-450W/P4=========>IC: TL 494 CN

As can be seen from above, most of this psu are using the same IC which is the 494 16-pin. The alphabet in front or the serial number can be ignored because it differs between different manufactures. The only exception here is the cap ayam model which uses the KA 7500 IC. But this IC can be moded the same way as the 494 does.

List of item needed for the mod:

~50k pot
~ some wire
~soldering stuff

Here's what you got to do:
You have to solder the pot to pin 1 of the IC and the other end of the pot to ground. Look at the diagram below:

[attachmentid=76496]

Remember to set the pot to full resistance before powering on. Decrease the value of the pot to make the voltage go higher.

2. 3.3v line mod.

The 3.3v was very difficult for me to find. The IC actually looks like a transistor (yes...a 3-pin IC). Luckily I notice the markings on the iCute pcb. Other transistors are mark with Qn (n=1,2,3...) but one transistor is marked with ICn...that's the IC that we're going to mod. Here are the list of psu and their IC.

~Digituz model: ATX-400W/P4==========>IC: TL 431
~L&C Technology model: LC-250ATX======>IC: SD 431
~Cap Ayam model: 300W psu==========>IC: TL 431
~iCute model: ATX-450W/P4===========>IC: TL 431 / CP 431

Again the alphabet in front or the serial number can be ignored because it differs between different manufactures. This mod is a little bit tricky because you have to find resistors connected to the Reference pin of this IC. Look at the diagram below.

List of item needed for the mod:

~10k pot
~ some wire
~soldering stuff

[attachmentid=76497]

For this mod you have to find the resistor R1. This resistor will be labeled differently on your psu pcb, so keep that in mind so that you will not mod the wrong resistor. To find this resistor, first you must find the IC. Determine the Ref pin and from there determine the resistor that is directly connected to this pin. There will be two resistors connected to this pin, one is connected to ground and the other is connected to a +v source. The one connected to the +v source is R1.

You will have to desolder one of the R1 resistor leg and connect it in series with a 10k pot like in the diagram. That's it, you're done.

Remember to set the pot at the lowest resistance before powering up the psu. Increase the pot resistance for higher voltage.

3. Applying the mod on iCute psu.

Here are some pictures and brief explanation of my modded iCute psu.

5v & 12v line mod

[attachmentid=76498]

50k pot connected between pin 1 and pin 7 of the TL494CN

3.3v line mod

[attachmentid=76499]

R1 is labeled as R77 on iCute pcb. Connect in series with 10k pot

Results

[attachmentid=76500]

[attachmentid=76501]

[attachmentid=76502]

4. Tips & Trick

1. Measure the voltages using a multimeter. Don't trust the readings of your bios or any third party apps.

2. You may use a trimmer instead of the large pot that I'm using. A trimmer is much smaller so can fit easily inside your psu.

3. Remember that for the 5v&12v mod lower resistance = higher volt but for the 3.3v mod higher resistance = higher volt.

4. Remember to set the pot to the highest resistance for 5v&12v and lowest resistance for 3.3v before turning on the psu.

5. Adjusting the pot on-the-fly while the pc is running is highly not recommended. You may burn other components of your pc if you accidently turn the pot too much. Adjust the pot outside your rig and measure using multimeter. To turn on the psu outside your rig, short the green wire with any black wire at the 20pin atx connector.

6. If you want to overclock your rig to the max, do yourself a favor and go buy those true power psu like antec and enermax. You wont regret it .(although i'm still stuck with my icute though )

That's it for now...happy modding
