9600XT Vmods

[bigZ]

I'm still in search of a vmod for my 9600XT, I'm in need of 700+ core ;)

I've taken pictures of the interesting areas of the card where I think the Vmods will be, but from looking at Unoid's images, my card doesn't have the same vregs.

VGPU mod area:

http://www.whos-j00r-daddeh.net/9600xtcore.jpg

I'm guessing that the chip close to the mosfets is going to feed vGPU right? That's where it seems most logical to assume the vMod area is. But I'm screwed if I know which leg I'm looking at

VMem mod area:

Help would be greatly appreciated! :cool:

[bigZ]

I've always been lead to believe that this was the best place on the internet for help with voltage modifications. Yet I've asked on 2 separate occasions with 2 different cards, and no-one can seem to be arsed to help me in my quest for finding more points for the XS 3dmark team. I'm trying to learn, but if no-one seems to be willing to help, I may as well go look somewhere else for a bit of advice and hope to feel a little more welcome. :(

I can't be the only person who's bought a Sapphire 9600XT Fireblade on these forums and someone who is a bit more clued up on voltage regulators than I am.

Thanks for the help, much appreciated. :toast:

[mattsmall]

isnt the 9600xt and the 9600pro vmod the same but with diff stock voltage?

[bigZ]

I've searched around the net for a good 2 weeks trying to find vmods, my vregs are different as I have said. They are a different size to anything on unoid's site, so that doesn't help me do the vmods.

[bachus_anonym]

take a look at the picture of 9600p within first link in vmods thread here (http://www.xtremesystems.org/forums/showthread.php?postid=368950#post368950). maybe that helps...

besides u will have to post what each of those chips are... write down all markings and post 'em here...

also, probably you're right with that vgpu vreg. leg below little hole on it is no. 1 so it might be same as on the picture in above link... then it could be pin5 to ground (pin7)... not sure until u check all those chips...

[bigZ]

Sorry I haven't got back before this, been having fun with nVidia detonator drivers and windows XP (*pukes*) over the weekend, so I've not had access to my email.

I'll take a look and list the chip codes, probably best to do this on a copy of the original diagram. I'm not at my own computer at the moment, but I'll post the chip codes later this evening. :)

[bigZ]

I've got the images of the card including the codes on the vregs now...

[bachus_anonym]

from what i can see (i'm kinda new to vmodding, so u should confirm that with others) that ISL6522CB is going to be voltage regulator for Vdd, not vgpu...
and also, it looks like there's no vreg for vgpu on those pics, so maybe:
1. that sticker with barcodes, pcb and serial numbers sit on little aluminium plate (can't see from that pic) which covers the vreg in question,

2. or u need to take some more pics, with the one with overall look of back side of the card...

EDIT: also before vmodding check voltages on all of those leads from caps visible on the first and second pics....

[bigZ]

righto, got an image of the back of the card, labelled anything that I haven't already labelled.

http://www.whos-j00r-daddeh.net/9600xtregs.jpg

there's nothing under the stickers, apart from a few small resistors

[bigZ]

right I've done some poking around with the multimeter, and this is what I came up with.

http://www.whos-j00r-daddeh.net/9600xtvolts.jpg

I'm guessing that my card is 1.3v core and 2.75v mem? Anyone throw anymore into this pot at all? :D

Cheers

[funktional]

I think the RT9202 chips have to be the ones you are searching for. All other chips are in the same place as on the reference layout.

you can find teh datasheet here: http://www.richtek.com.tw/Product/Docs/DS9202-02.pdf

The describtion seems to fit, pin 6 must be the one to mod.

this is only what I think. When I had my KT266a board and wanted to find the vdd mod I invested much time for research about vmods, how they work an how to find them. But I cant say that my skills are good enough to give a definately correct describtion. Its your choice if you are willing to risk it.

If you can measure the resistance between the RT9202s pin6 and ground i can suggest you how much resistance you should try but I might be wrong.

no risk no fun :toast:

[L337 M33P]

That *looks* like the Sapphire 9600XT Fireblade? But has Hynix RAM?

Anyway, the card I have has the very same chips ('cept for the RAM, 2.86ns Samsung :p) and the RT9202s control VGPU and VDDR. The middle controller (6522CB) is for the VDDQ.

I found that out in this OCforums thread (http://www.ocforums.com/showthread.php?s=&threadid=253909&highlight=9600XT+results) but haven't attempted the mod yet as my RAMsinks haven't come (damn radio spares)

[bachus_anonym]

i think u guys are right,

RT9202 - vgpu and vddd

as for ISL6522 (http://www.intersil.com/data/fn/fn9030.pdf) it has to be vddq controller bcoz when u look closely it has 4 solder points on the right and another 4 are underneath the chip. on 9500 and 9700 there is IRU3037A (http://www.irf.com/product-info/datasheets/data/iru3037.pdf) in exactly same palce. on those cards it controls vddq...

EDIT: i guess we all help eachother to learn anything here, ain't that right ? :-)

Yeah it's a Sapphire 9600XT Fireblade, good spot :D

Right then, I need to get this straight in my mind before I attempt the mod(s)

For the VGPU mod I'm connecting pin 6 to pin 3 on the IC which is towards the blanking plate end of the board with a 10k VR right? Or am I connecting pin 6 to a ground point on the card (blanking plate, etc)

Vmem would be nice, but I'm already at 374mem so I'm *fairly* happy with that :)

I mainly want to get the VGPU mod done and then I'll look to work at the VMEM mod :D

One step at a time, my first vmod I did was on the Xabre 200, and that's the only card vmod I've done, ever :D

My soldering is up to it though I feel. Just need some clarification on exactly which pins I'm modding before I warm the iron up. Thanks for the valuable input into this thread guys :toast:

NOOO!!! Pin3 goes to ground on VR and Pin6 to one of two other legs of VR. also if you didn't know before, pin1 is the one with little hole right next to it... also don't forget to set VR to max before soldering it in place...

there is alternative way of doing this mod to avoid soldering onto legs of that chip... but it requires "tracing" from those pins in question to find corresponding spots on the PCB... in that case u would be still doing same work on "VR side" but soldering points would be on the PCB and not that RT9202 chip...

good luck...

[bigZ]

http://www.whos-j00r-daddeh.net/9600xtcore2.jpg

Like this if my understanding is right?

<./n00b mode> :D

[bachus_anonym]

that's correct :)

[bigZ]

cool, thanks, now to find my stash of VR's :toast:

Thanks for the help guys :D

[bachus_anonym]

write down all voltages from the board and don't forget about checking them after, say, every VR turn.... in case the chip might be for something else than vgpu... (e.g. vddr, vddq or vref)... just to be sure since we're were not 100% positive about which chip is for what...

[bigZ]

ok... I've added the VR in... but a small problem.

Measuring from both the legs of the VR and from the ends of the wire that I've soldered on, I get 640 ohm no matter where the VR is turned to. Is this correct? :confused:

There is also no definite end to the turning on the VR, so how can I find the max resistance.

I hate asking silly questions but I'm not powering the card until I'm certain that what I have done is correct. :)

http://www.whos-j00r-daddeh.net/9600xtvgpumod.jpg

Thanks

[bigZ]

well, I've decided to throw caution to the wind and just turn it on :D

it worked, and I'm up to 1.4v where I was measuring 1.3v previously... time to do some testing :D

Thanks for everyone's help here, especially L337 M33P, bachus_anonym and of course funktional (the guy pushing me hard to get the scores that I am getting) for your input on this thread, without you guys, this wouldn't be possible :D

[kommando]

OT: Does placing heatsinks on mofsets do anything?

[bigZ]

which 'fets you meaning? on your motherboard or on the card?

I've got no additional cooling on my card, apart from the waterblock on the core. A big deskfan seems to do more than enough to cool down my memory :D

[bachus_anonym]

nice work, man... hope u will get it higher now :thumbsup:

[Bennah]

I have also got a Sapphire 9600XT and wanting to vmod the mem and gpu :)

I found this site out and its very usefull. Im going to do my vmods accordin to the information given on the site below.

http://www.unoid.net/9600pro/voltage.html

The BBA PCB is the same layout as my card. Ive already checked the voltages on my card using the guide and they look good.

Now I just need to get some 10K vr's and start moddin :)

My speeds I get now are 554 core and 349 mem on air.

[bigZ]

yeah unoid's site is a good resource, sadly in my case, my board wasn't the same layout as any of the boards he's got listed :(

But, we've managed to work out the mods and it seems like I've got a gem here :D

Good luck with the mods bennah, Maplin do the 10k VR's that you're after :)

[funktional]

Just did the vddq mod. This gave me artifact free 730MHz and a few more MHz on the RAM. :banana:

My problem with artifact at high voltages are also gone after the mod.

Now lets do some benching :cool:


btw. Someone should tell uniod about this

Edit: this is unbelievable 750MHz artifact free @1.6V
I wonder where this will end up.

[bigZ]

oooo sweet :D

I got 750Mhz with just the vGPU mod @ 1.55v, never tried for anything higher than that, but I was artefact free, just the odd tear from the mem being on the edge. :)

I'll have a look into vDDQ and vMEM though I think :D

No point having a half modded card when there is probably going to be more in this card still :D

But it bodes well for me - 590 @ stock cooling, same type of card :D

I wonder how it will do after some 1U cooler modding and ramsinks :)

[bachus_anonym]

glad u got this baby this high, bigZ...
go for vdd and vddq mods... they're easy as hell... and might help u that tearing ...

way to go, man

[enzoR]

anyone have a link for a VDDQ guide?

[bigZ]

VDDR is the large chip right? ISL6522CB?

Pin 5 and 7 are the two I want IIRC, if this diagram is correct: http://www.uploadit.org/L337M33P/blah-046.jpg

that would mean that VDDQ is the other RT9202 chip, I guess the mod is the same for that as it is for the VGPU mod? pin 3 and 6

argh double post

[L337 M33P]

The large chip in the middle is VDDq, as when I measured the voltage on surrouding caps I got a lower voltage there as opposed to the controller at the far end of the card. Pin 5 and 7 are the pins.

The mod for the VDDR chip at the other end of the board from the GPU voltage is the same - pins 3 and 6.

Welcome to Xtreme :D :cool:

[bigZ]

I ran 3DMark03 at 725/365 without the fan blowing, seems to be close to it's max. 732 hard locked and 730 was pretty colours :D

best I managed was 5089 on my 24/7 OS, no services disabled, nothing done to the OS at all :)

When I get my tweaked and de-cluttered DX9 install done I'll give it another whirl :)

I guess the card is getting a bit hot for it to artefact the way it was.

I seem to be having problems using the Quick Reply box... :confused:

edit: no wait, the time is screwed up :stick:

[bachus_anonym]

bigZ, get that soldering iron and do the remaining mods.... i'm curious what is the max of that 9600xt... :-)

[funktional]

L337 M33Ps you got it right. Why is your card still below 600MHz if you know all this :confused:
Come and join the club of the mid range xtreme overclockers ;)

The point to measure the vddq should be the one where you measured 1.38V.
If I go above 1.5V there I get artifacts again and gain no more OC but I ask myself what bigzs wondercard will be able to do.

You should do a 3dmark03 bench. Iam shure you'll place first there. While higher frequencies only give sligtly better scores in 2001 the 03 scales quite good. Im 3rd there with 2270MHz CPU only...

[bigZ]

the VDDQ mod is done, but I'm getting problems with Nature... vDDQ is set to 1.45v and vGPU is set to 1.55v... 751/373 will run about 15 seconds of nature and then the screen will have stripey effects (Like an RGB breakdown), and the computer crashes.

[bigZ]

slight improvement on my previous attempt... 752/374 vDDQ = 1.44v vGPU = 1.55v

17738 (http://service.futuremark.com/compare?2k1=7616322) - 7th overall now

:D

Could run some tests up to 774 core, so there is more to come once I work out wtf is going on with the nature crashing :)

[funktional]

774 :slobber:

What a great Overclock!
I wonder when you will pass 800 :toast:

My Score is 17345 now: http://service.futuremark.com/compare?2k1=7615503
752/378@ ~21°C Roomtemp as Im ill. I wonder what the card can do at lower Rommtemps.
I also found out that I can go a bit higher on the ram, probably 382 or so and I ordered 1GB KHX3000. :banana:

[bigZ]

I saw your score, that's some pretty top clocks too from that card :D

I had another go today... got sooooo close to 17800!

http://service.futuremark.com/compare?2k1=7617992

Here's what happens when I get my nature problem....

http://www.whos-j00r-daddeh.net/overclocking/uhhhtoomanyvolts.jpg

Never got a screen like that. Do higher Voltages help?
My current clocks are 775/780 but I gotta give the GPU almost 1.7V. Hope this wont kill my card but it remains quite cool so i think this isnt to bad for it.
Im close to 17500 with those clock rates. Cant wait to get my RAM :banana:

[ojdr2001]

Any hints for te vddq mod on GECUBE 9600XT?

Thanks

I have to lower the voltage thru Nature to get a run thru... I've tried vDDQ up to 1.50v and it was the same all the way to there, 1.44v seems to be all my card likes.

vGPU has been up to 1.62v but I saw no improvement there around 775 is the limit for the card due to getting limited by vDDQ which I can't seem to get stable thru Nature above 1.44v. 1.59v/1.44v is fine for my needs though, I've not seen much improvement in score above 762 core in all honesty due to CPU bottle necks

[NST6563]

Can someone post (with pics preferably) where the vddq and vgpu mods are? And what resistance values you're using?

I've done the vmem mod, and I did the vgpu mod that was on Unoids' site, but from what I'm reading, there's yet another mod that might get me some more mhz out of my card.

so far I've used 1 pot and 1 resistor for the two mods I have. used the pot on the vmem, and the resistor on the vgpu.

I'll post pics of my card in a little while to point out where I've moded.

right now I'm sitting at 630/745...and I'd LOVE to be at 700/745 at least.

Welcome to Xtreme :D :cool:

Thank you, Xtreme has a bigger voltmodding community than OCforums, which is where I usually live :)

L337 M33Ps you got it right. Why is your card still below 600MHz if you know all this

Because I am wating for Radio Spares to deliver me damn PGA sink that I plan to cut up :mad: - I have the GPU sink (a 1U copper Akasa-350 job) that I will put on but I want to do it all at once.

I am nearly there with the "tin foil" heatsink I have at the moment - 590MHz 3dmark stable/no artifacts. I got a really crummy score of 4200 though, but that was before I reinstalled WinXP. Haven't benched with the new install yet ;)

Just a note about VDDQ: I measured it on my card and got about 2.8V, which was close to VDDR but less than - :confused:

Anyway, be careful when modding VDDQ. You may fry the GPU by doing this mod as the voltage controls the input/output buffers of the RAM, and consequently affects the signal voltages.

[bigZ]

where did you measure VDDQ from L33T M33P?

I'm measuring from where it reads "1.38v" in this diagram (http://www.whos-j00r-daddeh.net/9600xtvolts.jpg) and I was getting an increase on that cap, so I just assumed that was the place where I was supposed to be measuring from. I didn't measure from the one which reads "2.75v" as I noticed an increase from the first place I measured :)

I'm not gonna have the card running again until vMEM is done, so I'll have to wait until then to find out if I got an increase on the 2.75v value.

[NST6563]

ok, so here's my card. Sapphire 9600xt. I've already done the VGPU and VMEM mods. I'd like to do the Vddq mod also. However, I'm not exactly sure what chip it is. So, I've taken a decent picture of the card, edited to show the spots I've got mods and the mod for vddq I have in question.

can someone tell me if that is in fact the right spot for Vddq, and if it uses the same pins as the vgpu mod? I would also need the location to read the vddq value.

So far, I can get 630/745 stable from my card @ 1.42v gpu and 2.95v ddr. If I up the vgpu to 1.45v-1.5v I can hit 650-660. However, since I still have stock cooling I'm holding off on that.

thanks,

http://pages.prodigy.net/jamesweber/9600xtmod.jpg

[funktional]

Vgpu and Vddq use the same chip, the vmod is equal for both. you should start with 10k ohms and go lower in little steps. The Vddq is a bit more dangerous than the other mods so you should be more carefull.

[NST6563]

Where do I read the vddq voltage from? Also, is there a ratio I should be looking at as far as what the target voltage of the vddq is compared to the vmem/vgpu?

I don't have another pot right now, so it'll have to wait anyway until radio smack get's more of them in, or I find somewhere else that has them locally.

[funktional]

http://www.whos-j00r-daddeh.net/9600xtvolts.jpg

The Vddq Voltage can be read where 1.38V is shown in that image.
Vddq voltages seem to work different on every card. bigZ cant go above 1.44V, my card does 1.49V and one of graces cards dies after she gave it 0.02V above normal

[NST6563]

that's a bummer. if it may kill my card I don't think I'll do it then. my nuts ain't that big...neither is my wallet...

however, the problem I run into with the current mods is that when I increase vgpu, I can't clock my ram as high. For instance, if I feed 1.45-1.5v to vgpu, and 2.95v to the ram, I can clock the core at around 650-660, and the memory can do a max of 340. The way I normally run the card with 1.42v vgpu and 2.95v mem, I can clock it at 630/372.

I've tried upping the vmem with the vgpu (1.5vgpu, 3.1vmem) but I get BAD artifacts when I raise the vmem above 3.05v.

Is there a way around this? maybe run a line from the PSU to the card to feed it the missing power? I'm no EE, so any help would be appreciated.

Hell yeah, I got lucky that I didn't kill my card after trying 1.49v vDDQ :D

[Bennah]

Can someone help me out, what is VDDQ?

So if I want to do a vmem and vgpu mods, do I just need 10K pots for both of the mods?

What would be a safe voltage for the mem and gpu. I'l check out the default voltages tonight.

Does anyone have stock mem speed of 325MHz (650MHz effective) The core is 500 stock.

At the moment without any mods I can get upto 550MHz core and 698MHz memory.

[NST6563]

I can't help you on the vddq, but I can run my card at 1.42vgpu and 2.95vmem. If I go higher on the vgpu, I can break 650mhz, but my mem overclock will drop. If I raise the vmem above 3.1v, I get artifacting at just about any speed above 340 (680ddr)

My stock speeds were 500/650 on my Sapphire.

10kpots are what you need.

[enzoR]

now... how about a vref :D

[enzoR]

no one up for it? or does it not exist on these cards?

[L337 M33P]

There are two further voltage regulators on the Sapphire cards - they are tiny 431s near the GPU. I don't know what they do but they could be Vref or something.

[bigZ]

I killed my card last night :( :(

I'm looking for a replacement RT9202, anyone know where I can get one from? preferably in the UK.

I was resoldering the vGPU mod as the vmod wasn't working when I fired it up... and one of the legs managed to fall off the IC :o

[Unoid]

If you guys find some working vmods to cards with different layouts than i got just send the info/pics over and I'll post them:

unoid@unoid.net

[enzoR]

the vddq mod is posted in this thread. maybe you could post it on your site, i'ms ure it would be helpfull.

[Unoid]

Hey guys I'm adding up the vgpu and vref mod to the site base don the info you guys have provided.

if you could e-mail me with the answers to the following:

1) What value resistors generally for the vref (need to be specific cuase of its easy ability to fry the card)

2) The Vmem chip and pins on your 9600xt sapphire. and if you guys could get me a large size front and back photo of your card.

thanks,

unoid@unoid.net

[Unoid]

Check out this thread guys:

http://www.xtremesystems.org/showthread.php?s=&threadid=31883

ever think of replacing or adding new capaciters to our boards for better speed/stability?

[bigZ]

If my card wasn't dead, I'd love to help you with the information for this mod... unfortunately the vGPU vreg got damaged during a resoldering excercise. I'm tryin to get hold of the part still. :)

[Unoid]

bigz Might I suggest buying SMD grabbers for IC's. they secure good enough not to need to solder and its much easier, especially wehn testing.

BTW great core score, highest I've ever seen.

Just to clear things up for others, the 1.38v is VREF. VREF is supposed to be equal to 0.50*VDDQ, its nice to know that it tracks correctly. VDD is supposed to be equal to VDDQ. Hopefully this should help others to keep their card from frying by modding VDDQ. VDDQ should be as close as possible to VDD.

[funktional]

I just didnt know what Vref and what Vddq is ;)

As we have the Vgpu, Vdd and Vref mod we should try to figure out the vddq mod.
The Vref helps the Vgpu. I can go to about 1.6V Vgpu before i get artifacts. If i raise the Vref to 1.5V I can go much higher- Vgpu tops out above 1.8V then.
The problem is that the RAM clocks go down if the Vref is raised. Vref and Vddq are linked (Vddq schueld be Vref*2) so the Vddq mod should help.

But where is the Vddq mod?

[enzoR]

Vdd = Vddq (in value) so i think that the Vdd mod also increases the Vddq.

The max vddq eguals the vddr but it usually is about 0.2 to 0.3V lower. All other ATI Cards I know (9700, 9800, 9000...) Have divided Vddq and Vddr circuits. I dont have enough knowledge to say if its different on the 9600s so any help would be greatly appreciated :)

As sommer is coming and as its quite warm in here i found out that temperature makes a good difference in overclocking the ram. I think Im gonna watercool it :cool:

[enzoR]

yea your right :)

The VREF mod that we have been doing maybe also increases the VDDQ then. could u check maybe?

in that pic above with the values i gathered that the 1.38v is the VREF, possible the 2.75v is the VDDQ, (could also be VDD)

so, if you increase vref, if that "2.75v" also increases then that is very well the VDDQ, and we wouldnt need to mod :)

[funktional]

yea your right. Increasing Vref also increases vddq.
So that doesnt solve the problem :(

[enzoR]

What problem? :confused:

[funktional]

The slow RAM problem. If its really cold I can bench at 382. I use 360 for playing. The vmod doesnt help really. going from 2.8V to 3.6V gives nearly no increase ~about 5MHz or so.

And the higher the GPU clocks and voltages so higher the Vmem must be or you have to lower the oc. Upping Vref helps to achieve higher GPU Voltages but the possible memory oc gets lower again. This really sucks as the card is already bandwith limited.
I hoped the vddq mod would help but it doesnt look like that.

Another idea:
look at the images on unoids homepage: http://www.unoid.net/9600pro/power.html

All the components for the FDD Power connector mod can be found twice on the older BBA, while they can be found once on the newer cards. As the components seem to be excatly the same might it be possible to do the FDD mod? if we can find the places to connect it?

[enzoR]

yea i have that mod on my 9600pro.. .

are all the voltages at the proper relation to each other though?

[funktional]

Yes, the relations are ok.

[NST6563]

I'd be interested in the FDD mod also...just did the LM63 mod, and the FDD mod would pretty much complete the card :)

I'm thinking of doing the vref mod this weekend. However, if I understand the way it works right, then I should "disable" the other mods before doing vref as changing vref will also change the other vmods....or am I thinking wrong?

[funktional]

Yes you're wrong ;)
The Vref Mod also changes vddq but it leaves the Vgpu and Vddr untouched.

[NST6563]

Originally posted by funktional

Ok, so I won't have to touch those then. But by modding vref, it also raises vddq, which (from what I understand) should be close to but less than vddr....ummm...right?:confused: and as long as it's within those limits it should be fine?

[funktional]

Yes thats right.
Vddq can be measured where the 2.75V value is shown in the image on page 3. I have to measure on the frontside of my card as the cap doesnt have legs that look through the PCB.

I just measured some voltages and connections on my card. I found some points that are directly connected to 12V and 5V from the PSU:
http://www.wakuebau.de/bilder/9600xt_volt.gif

HEres the datasheet for the 12V component: http://www.anpec.com.tw/products/download/PDF/APM7313a5.pdf

The 5V component is produced by fairchild but I cant find the Datasheet although I already had it before. But it also is an Dual channel enhanced mode MOSFET.

Would it be safe to connect the 12V and 5V directly from PSU to avoid the traces on the mobo? What about ground, would it be better to also connect the gronud directly from PSU to the card?

Edit: found datasheet #2: http://www.fairchildsemi.com/ds/FD/FDS6898A.pdf

[L337 M33P]

Connecting the PSU rails directly to the card would provide less noise and possibly more stable voltages - but I would advise against connecting another ground to the card - the last thing you need is ground loop problems.

[enzoR]

yea all booster mods only connected the + rails from the psu.

[funktional]

Ok, just connected 3.3, 5 and 12V to the card.
It changed nothing :toast:
Same overclocks as always.

bummer...I was hoping you found something there. If you were able to increase core while maintaining mem I would've done it also. Right now, if I increase vcore to get more Mhz, my mem speed needs to be lowered b/c artifacting no matter what voltage.

[enzoR]

why are you trying to supply power to the vmod chips? all they do is tell the mosfets how fast to switch on and off. you are ment to be doing that at the mosfets ;)

[enzoR]

btw what kinda cooling are you guys useing?

[NST6563]

do you think that connecting the power supply rails directly to the mosfets on the card would yield any benefit? maybe cure the problem that a lot of us have with raising vcore that tends to decrease the speed we can run our memory????

btw, cooling on my card is a P233MMX heatsink that has been modified by Mr. Dremel to fit on/around the components on the card. card runs at 40c when under a full load in games.

Could you please tell where I should connect the rails? a pic would be great :)

I use watercooling on my card. Never passes 30°C even with 1.8V.

Hopefully! :D

@ Functional

your idea of doing it to those chips was correct, but do the same thing to the mosfets... look for continuity on the mosfets to each of the rails, 5v,3.3v, and 12v. also check what voltage is fed to the mosfets. just do some probeing in other words ;)

ahh crap!Big z got me interested in this fore his card croaked.
Unless i steal my little brothers card and,blame it on him im not moving.Iwould love too c the whole project in detail,and with pictures.I planed a whole mod around this.Thats what i get fer stealing steling there ideas,but thats how ive gotten this far with my overclocking.Bigz if i had the dough id send u a card.If ur ever in the us stop by for dinner though.Thx fer the start bro cheers.

[chester]

I must have scared you all away with my spelling.I just switched cpus,and its a superlocked 2500.The cpu overclocks to 2450 with a CPUMARK04 of 4307.2nd page in 9600XT- all processors,but my 3DMARK03 has droped considerably.
How safe is this mod.Ihave the pots,and am ready,But i have a saphire radeon 9600XT which differs in pictures to whats being shown.Although the gpu is the same the samsung is the 2.8ns,and i havent seen that yet.
It overclocks to around 610cpu 355mem,but i would like at least 700-360.
These amd procesors are grat for the price.I was a pentium guy for like 5 yrs.Can anyone tell me how easy it is to do the pencile mod for a mobile?When i looked at the bridges they
seem to close for comfort.Thats looking through a magnifying glass!
If i can get this to use cpumsr will it fly?Somehow i believe if i could reach 10.5X? this thing could fly.With my unlocked 2600
the fsb stable was 240.Now im lucky to get 220 stable with geil3500 on a AN35ULTRA.I tried pin mod twice lol fore i found out

nice stock o/c there. with a bit of vmodding you just might hit that 750.

I dont see why you wouldn't be able to fix that permanently. I assume it's simply a voltage meter right?

[Flexus]

Where can I measure the memory voltage? At the 2.87V here (http://www.whos-j00r-daddeh.net/9600xtvolts.jpg) ? Im soldering the mods at the moment and I want to connect my voltmeter now..

edit: i have tested it.. core 1.3V@1.4V ram 2.65V@2.75

[Lifthanger]

Hi.
I think my card has the same layout as bigz's card. I think I know how to increase gpu core voltage, but I must confess that all these things you were talking about have confused me.
I want to get better oc on GPU and memory. At the mo its 530/640. really bad, considering the fact that I've got 2,8ns samsung ram.
So what do I have to do?
What's this VDD,VDDQ,VDDR,VREF,VREG all about? I just don't understand the meaning of most of these. :confused: #
I think gpu mod is done on the rt9202 in the upper right corner of the backside.
below is my card with all the relevant chips:

http://www.tomsoft.privat.t-online.de/lib/back.JPG

help would be appreciated...
just let me get happy with these damned 170€ I've spent... :cool:

[enzoR]

Have you visited Unoids site?

unoid.net

[enzoR]

sorry double post

I swear i only clicked once!
:(

[Lifthanger]

yeah of course..
I'LL read through it once more. :)
But I think it only explains the vgpu mod and the vref mod (I don't know what this does) .
And I think these things like vddq and so on aren't explained there.
You were talking about these things in this thread,so I guess you know what they mean..

[bigZ]

As far as I am aware, the RT9202 next to the APM7312 inbetween the memory chips is the VMem mod. That would have been the chip that I'd have modded before my card passed away to the voltage gods.

ISL6522B was the VREF voltage as far as I can remember... don't go above 1.45v on that, as you'll kill your card - default is 1.39v. I never got the chance to find any of the other mods because my card died before I got the chance. Also, I've got far too much on my plate at present; I've not 3DMarked for around 4 months now due to lack of time from spending most of my time reviewing graphics boards :)

I hope this helps a bit.

[Lifthanger]

so both Rt9202 are modded, with ipn 3 to ground on 10k resistor and pin 6 to the other leg. I'll try this out, as soon as I feel comfortable with soldering.
I wont try vref, as I don't know what it is ;). I'll post my results here, maybe I'll need some help, too.
Thanks for your help. :toast:

btw. I'd love to have your job :D

[bigZ]

vref helped me to gain a bit more on the core, around another 10MHz max with the same vGPU voltage.

[Lifthanger]

thanks. I think I don't need this.. don't want to go very high. I just want an oc like everyone else has. maybe 580/700..
I'll have some results till monday.
my cooler works nice already load temps don't go above 45C at stock voltage.

[Lifthanger]

my multimeter arrived finally.
I've used the same points, that you've used (in post number 10, you had 1,3core and 1,75 mem) and now I've got the explanation, why my card overclocks so bad..
1,27V core and 2,59V mem. very low values. me :stick: sapphire

[Flexus]

I thought I had burned my card yesterday... so I soldered the vr´s an and the cabels to the readout points from the card.. I´m happy that it works now because a bios reset an all the other things didn´t work.. the screen remained black

[Lifthanger]

all right.. I've done the vcore mod and it even works. with the pot at max, my vcore increased to 1.38V which lets me go to 580MHz clock. How high did you take your voltage for 24/7 use?
my Vref is at 1.28V which is very low.. maybe I should do something, too!?
vmem is 2.59V at the mo.
Well at first I'll do the mem mod tomorrow.
I've got a little problem, since I've done the mod, my memory wouldn't overclock at all. It starts artifacting at once even with core at stock speed. anyone else with such a problem?
I've done the mem mod and the mod to pin5,7 on the ISL chip.
What's the name of that mod? I thought it was vref and where you were measuring 1.38V on the picture (vmem where you got 2.75V) , but when I turn down the vr (to 5kOhm) nothing changes.The same is for the vmem mod I did to pin3,6 at the RT9202. How did it work out for you? esspecially to bigz who seems to have the same layout..

thanks
http://lifthanger.bei.t-onlie.de/backmodded.JPG

all right, I've found out, that Vmem is measured where you've got 2.87V..
but I still don't know what the mod on the ISL does.

[Flexus]

I have also the same layout, the vmem mod worked.. but i have soldered it from the card.. sorry

[Unoid]

flex, I've no clue for vgpu base don those pics.

[Flexus]

both mods worked on my card... vgpu 1,3@1.4V and vmem @2.75V.. but the pc didn´t boot after a few days

[=[PULSAR]=]

Getting a 9600XT Extreme does 500/680 default searching the forums and cant find a clean cut guide on where to measure and the vmods for gpu and ram. Some please link me or repost the guide, all the picture links are dead.

[NST6563]

hope this one helps. It's a sapphire 9600xt (mine). MOST 9600xt's should be a similar layout, and I've noticed that some brands use a different voltage regulator IC than others...but the mods are usually in the same place, you just need to verify which pins on your regulator IC so you don't smoke it.

http://pages.prodigy.net/jamesweber/9600xt/images/9600xtmod.jpg

[Flexus]

I want to do the Vgpu mod again... So pin 3+6 on the RT9202 chip with a 10k VR, but i don´t remember the readoutoints....

[enzoR]

i think its those 2 dots where the 10K VR is written. check with a multimeter.

NST6563 -> VDDQ???? is vddq ;)

[Flexus]

vgpu done, I check the voltages later when the card is installed...

Overall:

http://fl3xus.micha99.net/Andre%20Pix/9600XT-Mods.jpg

Hi guys, after doing the vgpu mod with a 10K pot, i managed to be the 1st r9600xt in the world for 3dmark05, for a few hours, till someone broke my record, 10 points higher :\

with the gpu 500@680 & mem 600@691 (no vdimm mod).

but i ran into a small problem, and i wanted to ask if anyone has that same problem too... when i raise the voltage over 1.40v, the gpu voltage falls down all the way back to 1.28v-1.29v... do you think its because of the 10k pot not working well or is it because of the card?

pictures of the vgpu mod will come soon...

[NST6563]

It may be falling back down due to overcurrent protection that's built into the card. I'm not sure how to get around that, but I'm sure someone on these boards does.

Nice overclock on that card though...congrats!
