Some 9700 Pro Volt Mod's

[Method Man]

Hello,

I've been looking around for some 9700 Pro volt mods and all I have been able to find is voltage measure points and Vmem mods...anyone got a link or a pic of some Vcore mods?

Currently running @ 400/355 no mods...Vref 1.48 Vdd(Vmem) 2.12 and Vgpu 1.60.The memory voltage looks like its already about its max so I don't think I will do that mod just the Vcore mod.


Thanks

[Method Man]

Well I just got done with the gpu mod :D and am running @ 1.7V gpu...going to see what improvment it made and mabe bump it up some more.

some pics of the mod.:toast:

[Method Man]

another :banana:

oh i see u have your system spread all over the table just like me

and you also use the antistatic bag as a surface for the mainboard just like me

that's cool :D

[Method Man]

Cool, I find that when its out of the case I get better temps and its easier to work with :p

Method Man,

I have a 9500np soft moded to a 9700p.

The infinion 3.3ns don't take to clocking too well...just barely over 300Mhz.

Do you have any links to some pics ?

I've read a little on the V mod for the GPU and memory can you shed any light on Vref ?

Also what components should I bee looking to buy to complete these ?

Any help would be most welcome as some of the links I've found from doing a search on this forum are dead.


TIA.

For the GPU mod I used http://www.extremeoverclocking.com/articles/guides/R9700_Vmod_1.html

http://www.rage3d.com/board/showthread.php?s=&threadid=33662242&perpage=20&pagenumber=1 has all the info on the vref mod.


Not sure if this will work on the 9500 though the board layout might be diffrent.

I did the Vgpu and Vmem mod tonight.

Using 10K & 50K VR's respectively I'm now running 1.65v for GPU (from 1.53v stock) and 3.05 for memory (from 2.88v stock).

I managed to clock the core to 378Mhz from 330Mhz and the ram from 303Mhz to 310Mhz. Its obvious the ram is holding me back to will most probably try the Vddq & Vref mods to try and help the ram. :D

@Method Man:

hi there !
I've got the same card but it's not modded yet ! :)
How far were u able to go before the mod and without peltier cooling ?

Thx

[Method Man]

It was always on the pelt...but before the mod I was stuck at 400mhz GPU.

Hey Method Man, I finally did the GPU mod, so far only using the settings that Extreme started with. (1.6v) What's probly a safe max voltage, just using good air-cooling, with a pretty sizable HS? Thanx, I appreciate any input. I'm VERY new to vmods, this is my second, after the vdd mod on my 8RDA+, & don't wanna toast it. :) BTW, mine's a built by ATI OEM 9700 Pro, in case it matters.

[luihed]

I run my 9700pro at 1.87v when benching... anything higher doesnt give me anymore mhz or stability..... at that voltage, I can run 3dmarks at 450/351...... thats aircooled using the stock AMD hsf....

[Method Man]

spaceman welcome to the world of modding :p: I think you should be safe @ 1.80V....you can up it more if you please just watch it if it starts to reboot the system or the monitor just shuts off.

[spaceman]

Cool, thanx luihed. :) I haven't really played with it yet, just runnin' at 348/348, but I can tell it's WAY better after the mod. :cool: Kinda hard to describe, but it just seems more stable now, especially gaming. I kinda think mine was a little under-volted, but I didn't know it. :rolleyes:

[spaceman]

And thanx, Method Man. I wasn't ignoring ya, one of my folding clients just sent in a WU, and my internet always slows to a crawl when that happens. ;) I realize I'll have to find my own sweet spot, once I get a feel for things, but it's good to know what neighborhood I'm playing in. :D

Having performed the GPU v mod - 3k set on VR i can get upto 400 on the core but there is black/white squares all over the place. Loosing the resistor down to just below 3k sorts this out but then i get hangs - i'm guessing heat related.

..http://www.thomaswhitt.free-online.co.uk/images/ScreenShots/radeon9700vmod_10.jpg

I have a cooljag copper heatsink and 60mm fan epoxied onto the Radeon 9500 core.

My question is this..Do i need to perform another vmod elsewhere to loose the squares. Thanks..

Oh and does anyone have a picture they could post that shows the voltages measuring points.

My card is Radeon 9500 Non Pro (soft modded to 9700) thanks

[spaceman]

Finally cranked it up to 1.85v, and I can run 3DMark01SE @436/348. :banana: Thanx again, guys. Gaming's WAY better, obviously. :D

[spaceman]

Yeah, I don't think I'm gonna try any more juice. Especially with air-cooling. ;) I'm gonna take Kunaak's advice and try it with Powerstrip tho, in case it'll do more. This is the max with Rage3D tweak.

I am at 396 gpu (9700pro sapphire) with a maze4gpu with no pelt. I went from 369 with the stock cooler (+ shinitsu paste). I am not doing too bad by the sound of it and I still have the shim on. Shinitsu paste is thick stuff and I put some silicone white goop on the shim for good measure. Water temp about 22'c.

what resistance u running for the vref and vmem mods jason?

gonna take the plunge and do them this week..

btw, the guide on the crucible says 20K and 50K for the rev 3.. what r u running?

[Çhrist0ph]

How much has anybody squeezed out of their Radeon 9X00 after vmods w/aircooling? Im stuck at 360/290 on my R9700NP (powercolor/infineon 3.3) and im thinking about doing a voltmod, but i dont have the big bux for wc'in pelts, would a vmod be worth it if its only on aircooling?

471 on the core of a 9700 is bad?

As for the voltmod, I am a little unclear which mod to do. There is the one Method Man did with SMD to pin 18, to ground.

Then there is the mod that uses a 2.7k resistor shunted between pin 18 and 20 as seen in this pichttp://www.xbitlabs.com/images/video/radeon9700pro-overclocking/vcore-res-s.jpg from XBIT LABS which gives 1.75v to the core.

Any idea on preference between these? I will be doing the mod on a Sapphire 9500.

:smileysex

[luihed]

Im using the mod on your picture but instead of a fixed resistor, i use a 10turn 10k pot.... my card is doing 465/360 now at 2v watercooled....:D

[Hondo]

I did the vgpu mod last night with the smd grabber and a 10k vr but have a few questions. I currently have the voltage on the card at 1.65. Is 1.8 or 1.85 safe with air cooling?

Stock the card would only do 342/342. I mounted a copper 1u heatsink on the core and used arctic silver epoxy to mount some heatsinks to the ram. With this setup the card would do 354/351. Definately not the best over clocker.

Weird thing is after the mod the core would do 385 with no artifacts at all but the ram had lowered to 344 or so. Anthing higher would give terrible horizontal lines all over the screen. Nothing like the usual triangels one sees when the ram is clocked to high. At 344 no triangles no graphic anomolies at all. At 346 the screen is so corrupted you can't even make out whats on it.

Also I noticed my 3dmark01 scores were not higher but actually were a bit lower. Didn't have a chance to run 3dmark03 or any other benches. There's no corruption on the screen with the core at 385 but since the performance is not better do i need to lowere it a bit or raise the voltage.

With regards to the memory, do i need a mem mod now as well. Why would raising the core affect the memory. Any help is much appreciated.

How much volts can I run through my Hercules 9700 non pro with Hynix 3.6ns? I now gets 3.35V and runs 345Mhz. Can I give it more V?

[DScamp]

god i wish that one of you would live near me to help me out...
