Gainward MX 460

[cahe]

In the beggining I must say I'm very new to vmods :-). The next thing You must know is that I've heard very good things about this forum, and how you help people with their o/c problems ;-). Anyway I've got this 'new' card to play with (getting some money for some real hot stuff like x800 or 6800 :-)) and I decided to break the world record in 3dmark2001SE :-))) (in this card category ofc :P)...

The PCB looks like this:



BIG VERSION OF THIS ;P

If you could describe the whole process as simple as possible I would be in heaven :P.

Thanks in advance... O/C maniacs ;P

Neither of the links works bud.

Give it another shot.

[cahe]

Works for me, but OK ;-). Meaby some connection problems. Here you go:

[cahe]

whatever ... ;-)

Tell me if the second server works or not...

[Starbearer]

I can see the first picture ... maybe the problem is at your isp.

I think what you have to mod is the chip IOR 3037A and the chip RT9164 ...

How? When am I going to check the current voltage? Are you sure about this? :-). I don't want to damage the card and this is my FIRST vmod ever ;-).

Try checking the voltages on the spot cirlced in green.

Post the markings on the chip circled in yellow.

The IOR3037A is a Vref regulator on the 9700 cards.

Meaby this will help...

[cahe]

I did a few mesurements...

[Hell-Fire]

Yeh, I thinks that prob right with the core and mem readings.

I still need to know what the markings are on the chips tho.

Also, can you give me a reading on the small chip that I circled in the pic a couple of posts up? Its the one near the bottom of the card. To the left of where you measure 4.71v.

I've sent you an email containing high resolution scan of the card.

Anyway - I'll post those marking in a minute ;-).

This small chip's voltage - 1,48V

I'll post those marking on a picture for better understanding ;-). My english is soooooooooo bad ;P

[cahe]

Here it goes...

Why can't I attach a file while editing my previous post?

[cahe]

Still waiting

This should help you, it is for vmem i think.

I 'll try to find vgpu.

375/700 mhz unmodded yet

I don't know much about theese things (electronic stuff :P)... could you explain it a bit?

Same for me ;-). But ATITool shows tiny, mini, micro artifacts... but who cares :P

[RaVeN155]

I don't like counting this all stuff :P i just solder some variable resistors toomorow and see what will happen. (sry for my english)

Raven.. U'r that guy from tweak.pl forum? :-)

[RaVeN155]

Yes thats me

Cool... 'cause I'm [cahe] from the same forum :P

[RaVeN155]

heh i knew it, i saw you sometimes :P and your photos have polish names :P

Anybody knows something about these chips?

I dunno what it is 1,57v, the same voltage is going to adj pin on us1150. It's AGP voltage because when i change vagp it have the same value.

And why on first chip is 1,47v and on second is 1,45v? Is'nt it the same voltage?

[RaVeN155]

So we have some problems guys, i've done vmem and i just think that voltage isnt the problem. 2,81v - 700mhz max => 3,50v - 700mhz max...

It is a mem max or some small chip can't handle more load?

[cahe]

Are you sure that vmem is done corectly? Meaby you aren't increasing the voltage of the memory but something else :P

[RaVeN155]

Yeah, i'm 100% sure. I just done vcore mod. And finally i'm happy ;]

stock voltage (1,6/2,8v) 375/700mhz
raised voltage (1,8/3,5v) 430/700mhz

i'm not going to give more V, because there is stock cooling, but it will be changed

Hello there Raven and cahe

Rav, could you use Lancer's freon cooler? Or you're going to use waterchiller?
