===========================
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!!!!

Here's another PSU mod. This time it's an Icute

+3.3V rail mod




+5V & +12V rail mod




Some results:

U modyfying the PSU?

Yup...that's me alright. Need some guide...read my guide HERE

eh eh.... y dont post our voltmodded 9550s oso man???

Later I post....there's a lot more waiting to be posted. Maybe tonight I'll post a few more. Searching my hard disk right now for all those voltmods photos

Here's some more mods that I've done.

My Gecube 9550GT. Core: 630 Mem: 290. Vgpu=1.6V / Vmem=2.65V. Give out 4838pts in 3dmark03 .




Another 9550 card that I mod. mADmAN's Colorful 9550 GD2.

waa, nice work man!! where did you learn all this thing??? if you higher the core voltage, won't ur gc got hotter???

ROFLMAO..Shah81,you're extreme man..

It's a very nice work done.

Did you adjust a maximum value for your GPU and Memory frequency?

If I come near your computer, my itchy hands might turn both the knobs of your graphic card to the maximum.

I learn all this in the world of cyber space.....with a lot of dead mobo and cards
Yeah...the GC will get hotter, so better cooling is needed. I use watercooling on my card.



Nah...my pot is inside the casing. When I close my side panel, you won't be able to touch it .
The ones with the external pot is mADmAN's card. He's a very lazy guy...... (@mADmAN: cool bro )
That's the highest stable frequency that I can get. Maybe I need some better cooling to get higher.


I'll post some more voltmod and recapping pic later. Common people....I wanna see your mods....maybe I should change the title to "Shah81 Hardmodding Gallery"

yo, you're a hard-modding sifu indeed

waa, looks like only shah dare to hard mod the pc

This is my FX5200....voltmoded with an AMD heatsink on it

ur the only one who does this kinda thing in LYN as far as i know dude...

should post a pic of ur modded mobo oso

.................

That's one of a hell job...
Respect u!!!

Can u mod my X800GT?
Asking if u can fit an AMD heatsink on top of it...
That's all i'm asking for...
Can aa?

Another thing...
How did u lock the AMD heatsink on that 9550 card?
I can't find any locking retention in the picture...

Or do u use screws?

Damn streamyx, got double posted!!!

This post has been edited by sHawTY: Aug 21 2006, 01:26 AM

drill holes on the heatsink aligned with the mounting holes on the GC then use screws....

I do remember some forumer who posted their voltmod here in overclocking section.....loooong time ago. I guess most of them retired already

Only have one moded mobo photo here. Damn I wish I had a digital camera back then, during Athlon Thunderbird & Duron era....lots of voltmod and dead mobo

That's not a 9550. It's my FX5200
mADmAN already answer

What is ur core and mem speed for ur fx5200??

can u teach me how to do all this things?

The highest speed that I got was 364/540 with 2134pts in 3dmark03. But the card is dead now......(R.I.P in Silicon Heaven )

I learn all of these on my own by reading and experimenting but you at least need some basic electronics (V=IR ?? ). If I can do it, so can you

i screwed up my electrics subject. haha. stupid mechanical got electrical, no mood to learn. currently using x550 ddr2, not different from 9550xt ddr2, thinking of modding it. i go cheras u do for me can ar?

ha shah....apa lagi??? business opportunity dah mari....

Tried to mod my LGA775 heatsink to fit on my X800GT...

Sadly, the heatsink is too big...
It's touching the PCI-E Slot...

Sigh...
Thinking of using Socket 478 Prescott heatsink later on...
The problem is, i don't have any unused Prescott Socket 478 heatsink...

Or, should i use AMD heatsink?

Wooow there....It's not as easy as that. It takes time to figure out how to mod a card because different manufacturer uses different circuits/components and I do need to do some research .

Unless you find a specific guide on how to mod your card, I cannot do it for you ...sorry..... unless you lend me your whole rig for a few days because I don't have a PCIE system to test it

This is a little out of topic. Maybe you can use PM next time

Use any heatsink that you like as long as it fits...but watch the weight. You don't wanna bend your card.

It's as simple as that

Still remember that moded FX5200. I burned an IC when I set the Vmem to 3V. Search the web for the IC and found it at Farnell. But during the desoldering process, I rip a few soldering pads. So this is what I do.......





And if you are wondering, the card works. But then I soldered back the voltmod and start overclocking again. This time I killed the card for good. I think I fried the ram at 3.1V

wah... u are a gc killer... but in a hardcore way... cool man...

That is cool man!!!

Yr soldering equipment must be the expensive.
Am i right?
equipment u used = equipment inside the silicon wafer factory

Nope just a normal 40W soldering iron. Wanna know what type of soldering iron I'm using....look at my avatar

hahahha bila master tunjuk belang .. huhuhu
sumer pawahhhh !!!

I still have a lot to do if i were insisting to use the LGA775 heatsink on my X800GT...

I have to cut a lot of things...
Right now, it's touching my PCI-E X16 Slot...

But one thing for sure, i can't use crossfire with this heatsink...

planning to voltmod my FX5200 too...but now no $$$, doubt tat later my card toasted like SHah81's card!

but nvm....maybe nxt week or 2 weeks later, i will post my LCD mod pic here when my LCD arrive! lol

Hey shah...
I got one Powercolor ATI Radeon 9550 with a burnt ic...
Can u replace it for me?

I am very sure that the only thing that makes it unuseable is because the burnt IC...

How do i know that ic is burnt, is by looking on the back of the card, there's an ic that has a burnt mark...

Can u do that for me?
Can u?
Can u?

I'm also using a 20X4 LCD panel here. Currently using LCD Smartie to control the LCD and it rocks

PM me the markings/serial no. on the IC and if possible include a photo. I'll see what I can do.

Here's some more. This time it's a capacitor replacement for my friend's Leadtek Geforce 4mx. The card uses the crappy GSC caps and 5 of them became bloated. Replace it with a Panasonic 6.3V 2200uf.
This cap is gigantic but I have no choice because thats the only caps I have in my box and I'm damn lazy to go hunting for caps. Have to solder one of the caps to the back of the card because it won't fit between the caps anymore.

Look at the size different



Finished product.

Shah, can u teach me how to voltmod my fx5200???

cool! mind to post some pic of it?
btw...do install it on the front bay? any idea howto cut a same dimension hole at the bay cover to fit with the lcd??

Yeah sure. Open up a new thread and post a high resolution pic of your card front and back. But there a some prerequisite....you got to have a multimeter and know how to operate one. Please google around for info regarding voltmodding and read it to familiarize yourself with voltmodding.
To be honest with you, you won't get much from the FX5200

Some guide from VR-Zone...errr but the pictures are missing. CLICK ME
There are also tons of other voltmod guides there. Be sure to check it out too. You might learn a thing or 2.

Maybe I'll post the pic later. Lazy to take it apart. Just measure with a ruler......

AGP Current Booster Mod.

Actually I got the idea from Shamino's PCI Express Current Booster Mod. After reading the article, I was wondering if it was possible to do the same on an AGP system. So I downloaded the AGP slot pinouts and start modding.
This is the out come

what did u get from voltmodding ur agp slot???

Here's a quote from Shamino's article:



Just replace the PCI Express slot with AGP Slot

wow this thread is crazy,,,, someone gonna be dead!

any significant or even noticeable improvement???

I don't wanna die......yet

Remember my 9550GT. When I bump the Vgpu over 1.6V, I have to crank up my 3.3V rail to 3.5V to get it stable in 3dmark03. Later I found out that the 3.3V rail on the card will droop around 0.2V during high load ( I measure this at the mosfets on the card ) although the 3.3V output from the PSU is actually stable.

After the mod, I can now bump the Vgpu over 1.6V while my 3.3V rail is set at 3.4V (I always keep my 3.3V at ~3.4V ) and the readings at the mosfets will only droop around 0.06V max during high load.

The AGP slot cannot provide enough current for power hungry cards. Thats why cards like 9800 and 6800 have power connectors on them. For cards like these, this mod will not be beneficial because the extra current is pumped through the connectors. But for cards without the power connectors, you might get some improvement in your overclock espescially if you voltmod.

For my 9550GT:

3.3V ----> Vgpu & Vddq
5V -----> Vmem

I mod the 12V because I had extra wire laying around

aper lagi???
buat ler..
tak yah dah pakai cross fire ko yg mahal tu...
ke wat kat crossfire tu sudehh....gagagagaag

anyway...shah..u are the man....try mod mid range or hi eng GC ar...

I always play with low-end stuff. No money to buy midrange stuff or even thinking about high-end stuff.
To me, voltmodding a high-end card is pointless. They are already powerful as they are but a little bit of OC won't hurt
Imagine frying a 7950 GX2 when a voltmod goes wrong

Wow Bro Shah,

now im really thinking of voltmodding my PSU and 9550

hehehe.... but as soon as they are out of warranty


Sweet Mods u have there, was thinking of modding my NF7-S RAM VOLT. it only goes up to 2.9v in bios, maybe can crank up to 3.3v for BH5 chips. ?

what do u think ?

The easiest way to get 3.3V is to take the 3.3V output of your PSU and feed it to the ram. But it wont be adjustable anymore. You'll get 3.3V all the time

Here's an example:
http://www.xtremesystems.org/forums/showthread.php?t=58507&highlight=nf7

whahahah ...
banyak lagi nak kena blajak dari abg shah nih..huhu

This is something not really related to voltmod. It is a pump relay for watercooling users. I've sold a few of these units to forumers here.

External view:



Internal view:



Here's the schematics. You can build one for yourself

ei... ic...from the circuit, means we no nid on or off from the wall socket, juz let it alwiz on then when pc switch on, it auto on.

yaww bro, can u mod my P3 HSF as i wanna replace my raddy x850 ori HSF.

can arr?? btw, where is ur place

wahlau.......hardcore(4core) modders lah!

u should work @ Defense dept lah! sure can mode Bomb to become
ultra Bomb

Which P3 HSF are you talking about, the slot 1 or the socket type. I can mod it for you if you want. I'm staying in downtown Cheras

Yeah, I'm hardcore

which part of cheras??
im talkin' bout old model dell gx.. kenot remember the exact model but it using those P3 750Mhz
btw, downtown cheras which area??

Ehh?
No more updates?

Anyway...
Shah, do you know how to find the best variable resistor for my freaking fast NIDEC DELTA V?

If can, please state how to find and where to find it...

And another thing, how do i connect it to the wires?
Which colour is for which pin on the variable resistor?

There are 4 wires...
Green, Yellow, Red, and Black...

Allngap said that the black and red are used for power
[Red for +VE & Black for -VE]

I've already asked allngap and he said, the extra 2 wires [Green & Yellow] is for connecting to a variable resistor to control the fan speed...

This is some information for my fan:



Help me...

http://www.nidec.com/designoptions/options.htm
refer to the -34 series as the nidec TA450DC's model number is C34262-34

in this case the yellow wire is the RPM sense as usual while the green is for the low/high voltage sensor

Well, its not like I'm voltmodding everyday I was expecting to see other people mods, but.................

To be honest, I don't know what value of resistance to use. Since you already asked allngap and he knows this stuff, why don't you refer to him.

Any type of variable resistor should do, preferably the ones that looks like a volume control knob.....easy to turn

You can buy those variable resistor at Jln Pasar usually around RM1~RM2. A little tip.....don't say variable resistor when you ask the sales person, use the word potentiometer a.k.a volume control.

Easiest way to slow your fan down....use 5V or 7V

Potentiometer...
Noted that...
5Volts - 7Volts...

Can't do that, coz it's too slow, it's the same like i'm using my old Thermaltake Smartfan... 73CFM maybe [For 7Volts]

While on 5Volts, it's like i'm using my vantec spectrum 120MM uv led...
Too slow...

All i wanted to do is to mod it to run on 9Volts...

Can someone help me here?

yo shah.... u think u can make a fan controller to control the FFB1212EHE?

3.0A

Actually I have a 4.0A prototype ( ) fan controller that I build for fun. But I never tested its full potential. Don't have any powerful fan with me. The most powerful I have is an NMB 120mm fan that suck 0.35A

But when you start playing with higher amps, the heat load gets bigger and you'll start seeing big heatsinks attach to the regulator.

Seduce us!!!

Show us that so called prototype!!!

well....ive got FOUR Delta FFBs for u to test simultaneously dude.... see if the controller can handle all of it at one go

EDIT: forgot to ask....

is ur prototype pwm based or is it based on voltage reduction? can make pwm based ah?

This post has been edited by mADmAN: Sep 9 2006, 12:17 PM

Regarding your last question on how to get 9V.....

You can use a 7809 voltage regulator. This regulator can supply max 1A, so it should be fine for your fan.

I'll put picture of the prototype later (bateri kamera habis).....but the design is not that efficient

I use a voltage regulator. I can build a pwm based for sure but a bit "leceh". Why suddenly want to use pwm??

coz voltage regulator might not work with the FFBs i have... i tested the fans and they work at 7v... but 5v mampus... was wondering if PWM might be able to bring it lower...

besides.. i was reading online that pwm doesnt produce as much heat as regulator

Oh...in that case, it should work for your FFBs since we are turning the 12V on and off. We only control the frequency but the voltage will always be 12V.

But 4 FFBs......3A X 4 = 12A

aiks?? sweating??? why la?? better make it 15A just to be safe man... give some extra room

u think it can be done ah?? can getthe right materials from jalan pasar?

This post has been edited by mADmAN: Sep 10 2006, 12:30 PM

Yeah can be done and components should be available at jalan pasar. But a single channel with 15A.....that's like building an amplifier already

The best method is to build a 4 channel controller with 5A each so you can control the fan individually. A little bit faster on the CPU but a tad slower on the HD.....keeps everything cool at the right speed

eh eh...not 15A per channel la bro... i meant 15A combined

but 4x5A (= 20A ) is better huh? hehehehhehehe..... anyway...me got a project for u one of these days if ur willing.

will PM u when i can think of the specifics

15A sure drains the psu a lot....lol!

Yeah...
15A...

It sucks half of my psu amps...

15 amps alot wor. 13amps household plug oso can kill ppl..........

Some update!!!!!

Bought a Gecube 9550XT 128mb card this week and the card arrive yesterday. Today the card look totally different

The Vgpu and Vdd have been modded


Vgpu


Vdd

Now with more Vdd, we'll need some extra cooling on DDR2 chip right





The GPU will be watercooled.......cheapo syscooling kit

wow! issit a chipset heatsink? u cut it wit hacksaw? lol

w00t!!! benchies dude!!! BENCHIES!!!!

Gila la ko ni shah...

Aku tau, tu ko potong dari amd stock heatsink kan?

Taknak tunjuk heatsink GPU ke?

I cut those ramsink from a cpu heatsink I bought for RM5 at lowyat second hand shop.....dunno what the heatsink is for
Benches later, need to sort out somethings first. It seems the GPU is not a really good batch.....need a lot of voltage to get up to speed
The DDR2 is preety good. It's a Samsung 3.3ns ram rated at 300MHz. At 2.0V, I manage to squeeze 340MHz out of it artifact free.....with the help of my monster heatsink.


@sHawTY
GPU is watercooled.

huh???? 3.3ns?? damn.... and 340 only?? i managed to get 425 highest with my old 9550 on infineon 2.8 ns WITHOUT vmod man .... after vmod tak sempat as u know what happened la

im still tempted to send my 6800 to u for vmod man.... at least if burn then can move to PCIe... but no moneyyyyyyyyyyy

EDIT: shah.. remember my 9550 heatsink?? any idea how i can use it ah?? feel sayang la the heatpipe no being used... cant think of anywayy to fit it to my NB and cant think of other uses for it any thoughts?

This post has been edited by mADmAN: Sep 18 2006, 01:12 AM

Ayoo....mine is 3.3ns only....rated 300MHz max cannot do much
Still having problems with my AGP slot. When I increase the voltage, the 3.3V rail will go like crazy on the card, but when I measure directly from PSU everything is OK.....I guess my mobo is not supplying enough current to the AGP slot since I already remove the AGP current booster mod.
Maybe need to supply 3.3V directly to the card from the PSU.......

updated shah..more update!!
rugi xanta nf7 aku..

hi bro, do u hav any idea for modding my old graphic card - gforce mx440?
can make it?

Sorry for the late reply....

Every graphic card can be voltmodded. You just have to find out how. I'm not sure how to voltmod a gforce mx440 because I never have one.

But if you have some pic of the card, we can start from there

Have you guys seen a 9550XT with a power connector??? I have one in my rig





That's a modded floppy power connector. Instead of supplying 5 & 12V, it is now supplying 3.3 & 5V (modded from the psu). 3.3V is for the Vgpu regulation circuit and 5V is for the Vdd regulation circuit. Both supply line is soldered to the input capacitor of each regulation circuit.

Results later......hehehehe

This post has been edited by Shah81: Sep 20 2006, 06:32 PM

ha.... with all this toying uve been doing with ur card...make sure none of ur small caps fall off again man...

Dgn terdampar nya wayar direct dari psu tu, aku pun nak tanya soalan ni kat ko shah...

Boleh ke ko buat camtu untuk graphic card PCI-E?

I've been very careful this time.....hehehehe

Semua graphic card pon bole buat, tapi kene tau laa kat mane nak solder. Lepas tu tak tau la ade mendatangkan faedah ke tak

Tapi untuk graphic card aku mmg berkesan la. Mungkin mobo nie teruk sikit.....tak supply cukup current kat AGP slot

kesian.. tengok my ex-GC .. kena rape LOL

halo, ur fx5200 is 128bits or 64bits? wut brand? i doubt is there any different to vmod between 128bits and 64bits. i noe most of the 128bits is done by connecting vr to pin 6 and pin 9 of the ic to ground.
