[persivore]

Can you post a picture of the back of the card please.

[klootzakje]

If you can get a pic of the back of the card, I'll try to find some mods :)

hi guys :bday2:
me's new here, i've been searching for the same thing on the x300 volt mod and i was referd here by another forum i've posted two piccys (about the best i can get from my camera)

can anybody pleaze help. the only thing holding me back now is a bit of power.

thanks guys :toast:

[persivore]

:welcome:

Can you tell me what is written on the chips I have circled please.

[sh0ck]

i've written the names down exactly as they stand on the chip.
thankx ;) http://users.over-clock.com/gallery/albums/userpics/10133/x300back%20details.jpg

[sh0ck]

oops forgot the large one on the front of the card near the bottom is

49DVERK
ACT86

[persivore]

I think the RT9214 chip is controlling the Vgpu, so for the GPU mod, connect a variable resistor between pin 6 and ground. I think 20k should be ok for the value of the variable resistor, but if you want me to confirm the value, can you check the resistance between pin 6 and ground, and pin 8 and pin 6. If you need me to mark any of the pins on a picture for you I will.

I think that the LM324 will be controlling the Vmem, so if you want Vmem mods as well, can you post a close-up pic of the LM324 area.

[sh0ck]

here's the memory chip

Would this be usable for say...a Sapphire X300 128MB 128bit card (stock core is 375Mhz, not 325) I'm just wondering because I have my DFI Ultra-D and 3000+ Venice on the way, and I wanna pickup an X300 to go for top spot on the ORB also once i get my h2O running on the Venice.

I'm planning on coming up with some crazy-a$$ custom aircooling for the card unless i can get a waterblock to fit and crank the volts.

I dont mean to try and hijack the thread, but any help would be much appreciated, cus I might stay away from the $700 vid cards for awhile and work on some $100 card high scores. :)

Hi!

Have got a X300 SE (64-bit) and want to mod the memory (vanilla DDR1, Hynix 5ns).

GPU goes to 450 MHz (325 MHz default) with 1.25V but does not improve results very much because of massive memory-bottleneck. Therefore no GPU mod needed.

Memory is 195 MHz (390 MHz) default and works stable up to 229 MHz (458 MHz). 235 MHz (470 MHz) and above results in corrupted textures.


I have located LM324-D and its pins. Already measured every pin against ground.

Here is close-up of front and back

http://mitglied.lycos.de/xxmartin99/x300se/front2.jpg

http://mitglied.lycos.de/xxmartin99/x300se/back2.jpg


The measured voltages are here:

http://mitglied.lycos.de/xxmartin99/x300se/LM324D.png


Bios health-monitoring reads 12V to 12.22V - exactly the voltage on the Vcc. 1.25V may be default-Vgpu, 2.49V default-Vmem for DDR1. However, I have no idea about those 2.26V and 4.62V. I am wondering why 1.25V und 2.49V are connected to input pins and not to outputs?

Don't think that 2.26V is Vgpu und 4.62V is Vmem?

Anyway - can someone please tell me how to increase vmem to 2.8-3.2V?
(what type of variable resistor)


The datasheet is here
http://www.onsemi.com/pub/Collateral/LM324-D.PDF


Thank you very much for any help!


Martin




// edit

I have measured input resistors and voltages around pin 9 and 10. The 2.60V are looking nice.

http://mitglied.lycos.de/xxmartin99/x300se/closeup.png

I guess, I have to connect Pin 9 to Pin 11 (ground) with variable resistor between?

[xxmartin]

Alright. Problem is solved.

Connected a 10K variable resistor between Pin 9 and Pin 11 (or any ground).

Vmem increased from 2.60V to 2.71V (measured on 423 Ohm resistor). Lowering the 10K resistor increases Vmem up to 3V+. Since I only wanted around 3.0-3.1V, I am happy now.

anybody know the vcore mod for saphier x300 128bit card?? i could post pics if needed

[wedfighter]

hi there...
we need ur help to vmod Abit X300se VGuru
it's a x300se w/ 128 bit mem interface
so far it can run 550/360
wonder if it's vmodded :toast:
pic will be available soon

[wedfighter]

here the pics...
the back of the card

and the IC are..
http://img388.imageshack.us/img388/5170/x300back4tr.jpg (http://imageshack.us)

please anyone....
how to vmod this card?
i'm using the VGuru software to monitor the temp and voltage
the default vgpu is around 1,2v and it changed to 1,30 and max @ 1,35v when we switched the Turbo mode (via Jumper)
vmem stock is 2,37v and changed to around 2,5v and max @ 2,67v

ADDED:
the memory chip is TSOP Samsung 3.6ns
i've ever done vmem mod on TSOP Hynix 3,6ns on my Leadtek GF6600 card, with 2,85v it can run @ 800MHz w/ changed timing

thx b4
for the respons....

[wedfighter]

anyone can help us?? :(

Hi,

I can help you or at least try...

--

APW7037A-chip is a voltage regulator, and generating either Vmem or Vcore. Datasheet can be found here:

http://www.anpec.com.tw/products/download/pdf/APW7037a6.pdf

Could you identify which mosfets/inductors/capacitors this regulator drives (pins 3,5) and after that measure voltage of over these output capacitors (to find out Vmem/Vcore ?). The output voltage of the regulator can be altered (raised) by connecting a (variable) resistor LARGE enough (say >10 kohm) between pin 1 and GND. When doing that: BE SURE TO HAVE MAXIMUM VALUE AT FIRST

Badly needed? I would think 1.35V would go pretty far with that gpu.

[persivore]

The APW7037A will probably be being used for Vgpu. Can someone check the resistance between pin 1 and ground on that chip please.

Can you also try to get a picture of the front of the card. I think the Vdd/Vddq regulators will probably be on the front of the card.

[wedfighter]

resistance beetween pin1 and ground is 688ohm
and here, pic of some resistors

I get 691 ohms. :D

[persivore]

Try connecting a 20k VR between pin 1 and ground. Decrease resistance to increase voltage. Find a Vgpu read point before doing the mod to check that it is Vgpu which is increasing :)

[wedfighter]

i've done a pencilling on R266 (the resistor which has one end ground and direct contact with pin 1 on the other side)
the original resistance is 688ohm, and now it's 675ohm, n then read the voltage via monitoring software (vGuru) and...found that my vmem is raised from 2,67 to 2,74v right now...:D :D :banana: :banana:
after some benchies, the mem can run @ 360 (720DDR) for hours :banana: , before mod it can only reach 300MHz (600DDR)
really quite extra frek for this Samsung 3,6ns with still naked :banana: (no ramsink yet :p: )
so it's the vmem regulator, right?
i wanna fully mod this card, can u show us how to raise the vgpu?
the gpu maxed out @ 580 @ around 1,35-1,37v :mad:
wonder if it vmodded :stick:
i'll be back with the front face pic of this card :)
Thx so much persivore :D :D :toast:

In a post from the 12th, you said the mem could already run at 360Mhz.

[wedfighter]

sorry Dr Jay, it just miss typed :)

[DrJay]

Cool. I'm very interested in your results as I have the same card.

[wedfighter]

with 2,8v for mem,it can reach 385 :banana:
see the attachment
meanwhile we've to wait for the front face pic, as my digicam not returned yet :(

DrJay, can u upload the front face pic? :)

[DrJay]

DrJay, can u upload the front face pic? :)

I'll try tomorrow. I'll have to borrow my girlfriend camera though.

Congrats on the memory speed! Very fast for ATI ddr1. I have a 9600xt with 2.5ns bga ram that will only do 10 mhz more....so, for tsop chips that is fantastic.

[HydroX]

here i can get. All out of the box, stock cooling etc, but i only use cat 4.9 driver, so bad :(

@HydroX
gpu not modded yet...it's still @ 1.35v
i'm using crappy watercooling i made my self
n i'm not using ice cube yet :)
wonder if it vmodded...

are u andiko, roller, embuh or d4ve :D
SOOT

[HydroX]

@wedfighter : i'm their friend, adrhyan :D

you give a pencil mark on that resistor, right ? how to do the vdimm mod without pencil , but using a variable resistor ?

well, and i want to do that vgpu mod now... :D

[SikaRippa]

About making mod: Could you 'HydroX' specify all marking codes of those two smaller IC (less than 20 pins) at top foto ? One is sited middle of capacitors and the other right/below of green capacitors.

[HydroX]

in the middle : APW7062A

but, now my card is in RMA progress, so i can't see what written on the chip below green caps

thanks :)

[wedfighter]

@wedfighter : i'm their friend, adrhyan :D
oh i see the John de Britto boy right? :D

well, and i want to do that vgpu mod now... :D
just put a 15K Variable Resistor beetween pin 1 of the APWand the ground, it exactly the same way with the pencil mod :)
and the vgpu mod is same as the vmem mod, but this time on the front board APW chip on the pin no.5 :)

[HydroX]

yeah, you're right :D

for the mod, when in school, i've thinking, the APW7037 pin 1 or the resistor direct to pin 1, for the Vddr mod, then APW7062A (in front side) pin 5 for the Vgpu mod, right ?

err...pin 5, so it's number 5 from the top right, correct ?


thanks...

EDIT : i can't do the mod now. i've blown my card when i measuring voltage ( my hand slipped) and BUFFFF, a fire over the IC :stick:

[brandinb]

i have a saphire x300 128 bit that i v-modded and i could not find any help on but i figured it out if anyone is interested i can make a thread otherwise its alot of work to write a guide and upload pics. some results tho stock volts 1.19
1.19-459mhz
1.7 596 benchable 590 stable
i can make pics and also i did cap mods to as the stock ones were really really scorching hott haha

never mind DrJay
i've done a vgpu mod anyway... :)
but..my card still in RMA progress this time, i've short circuit some resistors at the core, due to my careless when fitting a waterblock :mad:
the last time i've try the vgpu mod, i can hit 620 with 1,52v :D

@ Hydro X
yeah right definitely pin number 5 (located at the same row as the pin no.1 (pin with dot marking)) :toast:
