ATI/AMD HD2900XT ALL about it.....

[hipro5]

I'm starting this thread so to help each other with Mods/tips/etc involving this VGA....

First off, here is a SIMPLE WAY for guys that still have 2 x 6pins connectors and they can't make Overdrive to work......

Go and get a "crocodile grabber" like the picture below......



......and sort circuit the two pins of the VGA as shown in the picture below......




Another tip now....
Make your 2900's fan ALWAYS to work at FULL SPEED......
Get a 1KOhms resistor and place it between the YELLOW and the BLUE cables of the fan like the picture below.....



No soldering skills needed for the above "mods"......

I'll come up with more......

[Truckchase!]

Nice! Looking forward to more stuff....

[eXceeded]

Volt mods please

[Origin_Unknown]

will this work on the pro model aswell?

[Lightman]

Basic lessons done, lets get to something more interesting hipro5

I'm very interested in measurements points for vgpu because I'm getting Pro and silently hopping that it is under volted

[eXceeded]

We really need some software voltage adjustments...

[kemo]

Nice "Electric circuits 101" class DR . Hipro5 ,,

[Okda]

no i think the other end is shorted together

[hipro5]

@ Origin_Unknown: Yes I think it should be fine.....

As soon as I "naked" them, I'll upload much more.....This is a "general" ATI thread so to be all-in-one......

no i think the other end is shorted together

What do you mean?....

[Okda]

seems like the replies i replied to was deleted

he was wondering if the connector should be ground to the case itself or what

Ahhh.....

No need.....he can just sortcircuit the 2 "opened" pins of the 8pins connector and that's it....

Hipro, im curious, what board have you got the pair of 2900's on?

Hmmmm.........ONE VGA is best on ASUS Blitz DDR3.....CF?.....I'll have to test both(P35 - 975) under LN2 and I'll see.....On air ABIT AW9D-MAX is faster as for 3D with TWO VGAs...

Is it really necessary to get a hold of two 8-pin PCIe power adapters?
(mine seem to run fine with the "standard" 2x6-pin PCIe connectors..

if you plug the 8 pin in it lets you use ati overdrive, thats why the mod above is used. (read and you shall see)

the overdrive "only" sets fan speed at 100% then?

[quake6]

We want vmod for these

[DFI pit bull]

No, it lets you overclock the card.

[SKYMTL]

I am going to bring this thread up again to ask a burning question:

Crossfire Overclocking in a Vista x64 environment....is it possible without modded BIOS? Perhaps with a hardware mod to trick Vista?

[Crazypinoy9]

We want vmod for these

You mean like this???

[quake6]

Yes,but some better picture please

[Crazypinoy9]

Yes,but some better picture please

sorry...i took these with my bro's camera and i had some trouble getting a good shot. i'll take some better pics with my other camera tomorrow cuz the battery isn't charged.

[1Day]

vmod can be found here - text is German but pictures say it all really.
