mine read as 1.43V at stock, that would push 1.6V+ right? i'm on an ATI5 silencer here... will that be enough?
(i'm still trying to figure this mod out)

on the x800XL and x850 as a easy way to reprogram the regulator voltage during PWA stuffing should it ever be needed. You can just jump (Circuit Writer Pen) the solder pads. Both the 9800XT and the x800 AGP card use(d) the Fairchild FAN5240 regulator and use(d) traces on their PWA's to connect the required VID pins together.

that could make a simple solder mod to remove those resistors and shuffle them around....
and yes i get the idea, and had already looked at the pic. and i'll check mine, and see what needs to be done later my bro kinda killed my winnie 3200+ and a neo2 plat board, so i've got people to kill and RMA's to do today...

Tijgert: Dropped you an email regarding to modding Club 3D X800 PCI-E, Dual DVI, VIVO to 16pipe XL model.
You seem to have that Club3D XL model allready... could you send me the original bios of that card? I ordered yesterday the Club3D X800 PCI-E card and i´m wondering if the 12-->16 pipe mod could be done to this card. The PCB:s seem to be identical according to pictures published by Club3D. Anyone has advice if and how the flashing could be done? ...if i do the flash with the modified flashrom and the XL-bios should all the 16 pipes be activated or do we need some kind of a special bios? |

it could be laser cut, in which case its impossible to unlock.
(like the non-ViVo X800PRO cards)

Thanks for testing the VID mod for me, I havent had time yet.
To do the resistors, I would recommend using SMD 1k ones, (0805 size). There are two ways of using SMD resistors: 1) Put a very small blob of super/other glue in the middle (not on the ends of the resistor) and just push it down with a pair of tweezers so that the ends make resonable contact. I think this is the best way, partially becuase it can be removed and noone will ever know if you send it back, where as they will if you paint it. Might be easyer to put the glue betwen the solderpads. After glueing it down, its a good idea to cover with hotglue or something to protect it. 2) Soldering them was quite hard for me but I am using a 1.5mm tip on a cheap 30w iron (£5 from maplin). With a 18w iron with 0.5mm tip it should be really easy.. Ive done a few tests with a dead 9700 on some very similar solder pads and It took a while.. the reistor was hot for about a minute (stuck to the soldering iron tip, lol) but it works and measures 1k. Pencil doesnt seem to work atall on these cards, I think becuase the solder pads are bumpy instead of flat.. If they were flat then the pencil line would be straight and not curved over the surface. I would not use conductive paint... they're must be a reson why they used 1k resistors... Last edited by Kramdra; May 28, 2005 at 12:46 AM. |

I assumed the resistors were used because a zero resistance might take more current than the chip can source/sink and damage it? If not, then its definatly easyer just to jump it. To jump it I would still not recommend pen unless you want it to be 100% permenant with no chance of sending it back under warranty... I will try with conductive copper tape which is sticky on one side, perfect for doing this... and non permanent.. Ill hot-glue over the top as always ![]() I think for anyone watercooled that cba with the IGPU mod, it should be good to just stick the GPU at 1.6v. It overvolts on most cards by 0.1-25v anyway.. which is just below what the OCP kicks in at? |

I have a question.....
I'd like to get a 1.45 GPU volt, I can easily do 1.40, but in order to do a 1.45 I would have to open up one of the resistors. I am doing the pencil mod, but is it possible to get a 1.45 with a pencil mod? Would I just pencil them in like I did the VDD mods? Also if I wanted a VDD of 2.25, would I need a VDDQ of like 2.28? Are those safe for air cooling, with an AC5 Rev 2 on the XL? |

Also I managed to mess up my attempted voltmods on the X800Pro I was playing around with - Doctor John used some of his SnakeMagic to make it fly again... |

This may sound like a dumb question..
![]() But when doing the mod with pots what do I set them to before installation.. ? Do I test them with my dmm to 0 ohms.. or 20k ? |

Im a bit confused with the VID mod.
Ive got a 1.4v stock card. I should now be getting 1.6v. When testing Ive gone to bios so it doesnt boot windows. I assume the VID will not start at 1.4 then change to 1.6v in windows/games etc.. it should *always* be 1.6? I bridged R1856 (VID3) using sticky copper tape which is conductive. The connection is not perfect, I cant get the resistance lower than 650ohm and I think thats the reson why it *doesnt* work. The connection is probably just not good enough. Heres a pic of it, before I redo it with solder.. pic. Also does anyone bother to cool the chips Ive put large blue rectances around? I dont think they make much heat - instead on the other side there is two inductors which make the heat (and they work better when hot). Ive not looked up the fucntion of these chips yet.. but it might reduce droop on Vgpu if they are cooled..? I assume like with CPU voltage the droop will increase a lot if voltage is increased above what the circuit is designed to give. Last edited by Kramdra; Jun 12, 2005 at 11:23 AM. |
