radeon 9500/9700 "new" pcb 3.0 vmem mod partially discovered!

[Dane]

my ram aren't so good

@3.33v I run very stable without ramsink and artifacts @ 317

but the gpu......... 470/480

I don't know how Danes' card is doing, but, I was running my 9500np at this everyday and on AIR with a 3Dmark03 score of 6095! VDDQ=2.800v, Vgpu=1.820v, Vref=1.350v and VDD=3.503v!
Now if my new 9800pro would just do that!

wow... so how long have you ran the vdd @ 3.5?

I'm not sure what the best settings are for the VR's, but I set them all (for Vdd, Vref, and Vddq) to 2.7k Ohms and started adjusting from there...

I didn't burn out my card or anything, so it's a pretty safe place to start. If anyone else knows what to set them to, feel free to let us know!

[DisposableHero]

for VDD i just put it on at 10k ohms... and it put me right away at 3.05 or so... how could you possibly put it to 2.7k

btw.. what voltages are you running on each

[Dane]

I think that using 2.7k for all mods will burn the board

I used a 10k vr on the Vgpu (it measured 9.7+k) and it raised my voltaged to 1.7v default. I used 20k vr's on everything else, setting them to their max ohm readings...I got a default voltage increase even with 20k vrs of : VDD=3.11v, Edit://Vref=1.374 (should be Vref=1.324v) Edit://, VDDQ=2.76v.

Hygge over at rage3d forums was running VDD=3.64v.

Since I've retired the 9500np I'm going to lower everything back to default volts...it's a great card!

[Dane]

hobocrow, I use trimmers like you.

3.64v is 28% vmem increase (2.85v = stock)
3.33v is only 17%

I run without problems and ramsinks @3.33.
with active cooling on ramchips I think that 3.64v is good only for some bench.

Dane I used trimmers like you! You were first!

I'm sure increased voltages will shorten the cards life, but you gotta cool it and turn it up for benching!

[DisposableHero]

what do you think is an ok everyday use voltage? 3.2?

[Dane]

yes,
It's 12% overvolt.
If you use a good cooling I think that 3.2v is acceptable.

[RuKuS]

Thanks for letting these guys know where to set them. As I said, I started off at that and adjusted immediately. I did not burn my card.


I'm currently running the memory at 3.3v, no problems yet!

for how long now?

About a month. When I first got the card and was benching, I had raised it all the way up to 3.6v!

I managed to get the memory to 347 MHz, @ 3.4v with no problems whatsoever. I didn't try any higher because I need to get some ramsinks (on the way).

Here's a 3DMark score:

[Dane]

which bios are you using, rukus?

[Ragnarok]

so wats the verdict

whats a safe starting resistance for vcore/vref/vdd/vddq?

[BMORIN]

Exactly. I don't have the equipment or the know-how to get all the voltage measurements.

I'm just wanting someone to help out us idiots by just giving us the resistor sizes to get a good overclock on all the mods.

I don't see the need for the vcore (vgpu) mod since my 8rda+ already lets me choose up to 1.8vagp already. Correct? Or am I stupid and need the vcore mod as well?

Thx

[Ragnarok]

vagp doesnt affect vgpu..

setting it higher wont do crap..

[BMORIN]

ahh, thx. I'm just an idiot then, hehe.

RESISTOR SIZES PLZ FOR EACH MOD

[The Juice]

Dane, I have the same card you have. However I cannot seem to overclock it for crap, I may have the wrong bios. What bios do you have for your card? There only seems to be one bios on Wizzards website that will work with this card, maybe I missed one or you got yours from somewhere else. Could you maybe backup your cards bios and post a link to it so I may download it? Thanks.

[Pita^Norf]

Hi,

A quick question...what BIOS are the 9500np users running ? and where can I get it ?

TIA

[naughty_guy]

Hey guys... I got a few question as a Vmod newbie.

I know by upping the VDD and Vcore will significantly help OCing the core and memory, but will upping the vref or vddq help in anyway??

And what do you guys suggest as maximum voltage for all of them (air cooled)??

Finally, what will be good Ohm settings for VDD and Vcore to start with? What Ohm will give default voltage for them? What are their default voltages?

Thx

Naughty_guy,

Apart from a few thread on this forum I found the following threads most helpful as the info for all the mods were concentrated here & here
