be careful what you touch with the multimeter.. i touched 2 pins that was posted was a place to test voltage and ended up sparking and shorting my motherboard killing it

**youthemandan** · 02-18-2003, 08:55 AM

What is the most Vmem i can give my new 9700 pro and not kill it. I plan on using ramsinks and i imagine the steam off the LN will cool them somewhat

**DisposableHero** · 02-18-2003, 05:50 PM

i think 3v was the max safe

**youthemandan** · 02-19-2003, 09:14 AM

Can i give my vgpu 2.0v and get away with that. It's gonna be LN2 cooled so cooling is not a problem

Hi everybody,

I'm an italian guy (sorry for my bad english!) and I'm trying to do my first V-MOD on my Hercules 9700PRO.
I've already OC it to 420/720MHz, using it always @400/700MHz.
Now I'm doing the V-MOD, but I'm not so good to join this small component with the stain.. so I'd like to ask you all a little thing about it.

I've seen this "standard" mod (for the MEM V-MOD):

and this other one, made by the Italian guy Varenne (from HW, you know?):

It seems that he has used different point for this operation, and it seems really easier for me!!

Is it right, too? I've no problem for the ground (so many points to join it!!), but just for the other point, and by this ways I think I can solve my problem..

Thanks for all,

Luca

You might want to consider using an SMD grabber instead of soldering (will not show visible evidence of mod. voiding warranty) and a 20-turn "Trimmer" type potentiometer will allow you to make very small voltage adjustments so IMHO is better for overclocking than a fixed resistor because it allows for finer adjustments of voltages than BIOS controls on your MB will.

I am not sure of the the contact points where they connected directly to the board, but the placement of the resistor on the legs of the IC looks correct.

Thanks a lot zippyc,

tonight I've done my first "experiment" with this V-MOD, and I've used an SMD grabber like this one:

http://www.kanda.com/images/img029.jpg

with a normal resistor (just for trying, cause I didn't want to take my tester!

), but I want to do this mod with "Trimmers" and SMD grabber, when it is possible...

THANKS A LOT AGAIN...

waiting for other answers..

**bronco113** · 03-06-2003, 07:35 AM

..is "the contact points where they connected directly to the board", I don't want to TRY BY MYSELF with a 500â‚¬ board!!

**zippyc** · 03-06-2003, 07:40 AM

and although I think I can solder ok, I sure feel more comfortable with somthing I can remove at will....

And (sarcasm here) it certainly has nothing to do with the fact that this card costs as much as a low-end computer!

**bronco113** · 03-06-2003, 07:50 AM

MY problem is the "INTERSIL ISL6522CB" for the MEM V-MOD (not just the other one for the VPU V-MOD) cause with this one I'm not able to use my SMD grabber.. there's not enough space!!!!

And so.. I'm trying different ways, like the one by "Varenne"...

**bronco113** · 03-06-2003, 08:25 AM

* MrIcee : can U help me? PLEASE...

THANKS for all,

you seems to be one of the BEST "MODDER" of the world..

**bowman1964** · 03-06-2003, 08:54 AM

guy's i know alot like to use the grabber instead of soldering,but i still solder and return mine no problem.
when i remove my soldered joint no one will tell i was there.
if you use Desoldering Braid to completely remove any traces of solder.grabbers are nice but i have problems sometimes with them making good contact.

Not quite wanting to mod my card but repair it. The 'heatsink' over the (VPU?) voltage reg section of a 9700pro was loose and it looks like thermal runaway toasted at least one IC. Anybody able to furnish me with details of two of the four ICs, I know one is a 3037A and the other 4804, both of which look okay.

find out which one is ground then u dont need to use a grabber for that one.. just put that one the the case or ground wire on molex...

**BLHealthy4life** · 05-06-2003, 06:41 PM

I REALLY REALLY want to see the 9700 volt mod posted by Mricee. I click the link and it says that I can't access the file directly or something like that. anyone having the same problem? I really want to over clock my card and NEED this guide. If the link is invalid, can someone send me the guide somehow please. Thanks!

**Walrusbonzo** · 05-07-2003, 11:07 PM

Does anyone know what the original resistance values are for the VCore and VDD?

I'm trying to work out what resistor to use for these mods.

I have 2.7k, 3k, 10k, 12k and 15k resistors at my disposal.

What do you think I should use for VCore and VMem baring in mind I'm using stock HSF for VCore but I removed the shim, I'm using shin etsu paste and I have lots of air cooling in the case. I also have ramsinks on all the RAM.

Thanks

Hey all, new member here. I must say you guys got me hooked on this site, been reading it for the past 2 hours lol! I just read thru a plethora of pages regarding the vmod for the R300 core, haven't read anything about the vdd mod tho. I wouldn't mind soldering but I would prefer trying with the SMD grabber first. I notice that this is quite an old method but I would appreciate any tips at all.

**`schr0et** · 05-11-2003, 10:06 PM

Oh BTW I have a Built by Radeon 9500 Pro with 3,3 Inf memory currently playing games with it at 331/311.

**Goldlocke** · 06-18-2003, 08:53 AM

@ moderators: the link to MrIcee's voltmod guide is broken. It links to an empty Xtremesys-page.

**Crozet** · 06-28-2003, 07:14 PM

Can you please fix the link.It is broken!
thx

why it's not possible to use grabbers modding the 9700pro?! don't have enought space?!

who said that, you on crack?

**DBurton** · 07-02-2003, 09:03 PM

My card looks like this:

http://thecrucible.ca/images/old_mem.jpg

Can anyone confirm that this the vmod in this picture is correct? Also, is there a list anywhere of the different levels of resistance and the resulting voltage of them? I would prefer to use fixed resistors
