Geoffrey's 7300GT worklog
 

Someone wasn't home today :no:



Sexy pictures tomorrow, for now I leave you with specs of my test setup:

Intel Core 2 Duo E6600
TEAMGROUP DDR2 PC6400 Cas4
Abit Fatal1ty FP-IN9 SLI or ASUS P5B Deluxe
Zotac 7300GT, atleast that's what should be in that package
Silverstone 750W PSU
HD -> I hope I have one left :s

Lucky number 13:



Inside the box:



Single slot card, for now...



No extra power connectors, but I can always add one myself :)

Underneath the heatsink we find the GPU where Silver based thermal grease is being applied.



This card is equipped with 4x32Mb memory, brand: Samsung.



The GPU core:



The front cover of the heatsink can be removed with 4 screws, though to a low amount of fins this heatsink will be as good as unusable:



Enjoy the weekend!

Nice pictures! Which camera did you use?

he has build himself a light box, very cool, cheap and the effect it has on pics is amazing as you can see, camera can be pretty much any half decent digicam:)

woah, nice :)

I tried to build one of those JMke posted above, but it didn't work out as good as it supposed to be. My second build was even more simple, but very effective in the end. In fact, you only need a box and white paper to build it. First you need to remove the top and side panel of the box so that light can fall in on top of your object, and so that you have all the space to point your camera. Then make the box white inside so that you have a clean white background on your pictures. White also reflects light and so shaduws can be made less dark, though I do not think it's that effective in my 'lightbox'.
I decorated my box with white paper but that seem to lose it's color over time and so I moved on to a white bedsheet. In very detailled pictures you can with no doubt still see the uneven surface of the sheet I normally use.
As lightsource, nothing special either, I put my box underneath a simple TL-lamp which we are using in our kitchen.

My camera, a Traveller Slimline X5, is not one of the best camera's out there. Pictures have a high failure rate if taken on 'auto' mode, so every time I turn on the cam I always have to run through the configuration menu in order to get the pictures looking like how I want them to be. Most of the time I take one picture and then I retake it with a different 'light configuration' just so that I have the luxury to choose the best out if both. And even then I the final set is not all that great, most of the time Photoshop is being used to further improve the pictures.

Voltage read points, seems like people are allready in high need of voltage modifications :)

More tomorrow

The chips near the readout points are probably the voltage regulators for gpu/mem?

So FB to GND ? :D

Let's hope so, I'm not a soldering wizard, but some SMD grabbers could do the trick for me.

FB to GND will do the trick in most cases, though it's always good to know how the circuit is made instead of just playing the 'trial & error'-game

The chip in the memory PWM modded FB to GND doesn't give anything. I don't think that's the chip we need ;)

Are you sure? Maybe your VR's resistance was to high to notice any increase?

Confirmed by Blind-ripper,

Lowering resistance at pin 4 (green) to 380 ohm should be no problem with air cooled VGA cards.

Have fun ;-)

hard & soft voltmod in one, nice! :D

Damn, hardmod on memory fried it ... only 2.07v though

did u put any sinks on the mosfets ? :D

not on the mosfets, but on the mem chips.

I say it again, please be careful with the vmem mod! I only used 2.07v instead of 2.00v !

Seems like Massman had a bad GND contact when he tried earlier today.

Blind and Massman, thx for testing, it seems like memory has to be handled with extreme causion.

So your card is dead ?
Hmm...
Are you sure it's only 2.07 ?

sadly enough the vcore pencil mod is not working for me :)

I putted 1cm of pencil though...

neither here, must use hardmod.
Luckely, I'm home on wednesday's :p

Looks like it worked, I got about 30 extra on the core.

what did work? teh hardmod?

No, pencilmod.

serious? lol might have to change my pencil then :)

use a heavy B2 pencil ;)

Yep, I used a B2.
No idea what the volts are for now.

plz check gamer : stock vgpu should be 1.375vgpu , on the chip thats 412ohms , 388omhs on the chip is 1.402vgpu ;)

Vgpu pencil mod working here :).

Dno voltages, but i can bench now at 657 MHz core speed :D :devil:

Massman, mail me for deal on 2nd card;)

Tomorow vmod on the card and a testrun :)

Question, I got a 820 Ohm resistor here, will this help ?

no best is to use is a 20k ohms VR ;)

You sure, this one worked on my Ti4600 to get 1.9V
Omh is to low or what ?

why use 20K instead of 10K, you can be preciser with that ;)
using 20K as well :)

That doesn't answer my question :)
Ok, will see if I have the time to get one.
How's that shop called where they sell that stuff ?
Gotron ?

820 Ohm = 0.8Kohm

a 10Kohm is requierd..

what volatge would you get right away at 0.8Kohm :D

I have no clue, you tell me :)
So, if i get a 10Kohm resistor, it should be fine ?
My multimeter is faulty, so can't mesure it :(

it should be fine yes :)

use your other sensor :D

For those who want to fry their memory I've included a self explaining Vmem mod picture.
