Buildzoid Creates Frankenstein Radeon 290X with Three Power Boards

Buildzoid is back at it again on his Actually Hardcore Overclocking YouTube channel with two videos that cover his most recent adventures. The videos center on the fun he has been having with a GALAX HoF Power Board that he has used to bring back to life his dead Radeon 290X card. The videos provide an interesting and insightful look into graphics card modding.

So what exactly is a Power Board? Well, for the uninitiated it’s basically a pretty simple PCB that contains the VRM components that would usually be used to power either the GPU on a graphics card, or the CPU on a motherboard. The GALAX Hall of Fame (HoF) Power Board is in most respects similar to competing products from GIGABYTE, ASUS and EVGA. The HoF board supports up to 2GHz switching using an IR3595 PWM chip. Each of the 16-phases is based on an IR3555M Mosfet ICs which provide an input current up to 960A. Plenty of juice in other words. More than enough for pretty much any GPU.

The second video is all about the Frankenstein-like Radeon 290X card. The HoF board is used to power the Vcore while he has an old 7870 VRM powering the auxiliary rail while yet another board, a GTR power board powers the card’s memory. Strap an LN2 to the side of the card and you have a pretty nuts looking rig that is well prepped for extreme overclocking. If it doesn’t burn your house down that is.

You can find the HoF Power Board video here on the AHCO YouTube channel, plus the resulting modified Radeon 290X card in action here.

LoL

because he can
Sometimes it's that easy.

Interested to see how this will go on

Czech Republic buildzoid says:

currently have issues with the card refusing to run with drivers installed. Not sure if that's due to some safety feature going off or because the core on this card was dead. This card was sitting without a working Vcore for like 2 years before I did this.

From what I recall the GPU needs SVI2 hooked up to operate properly.

hooked up to what? because I can't see myself getting the IR 3567B working on this thing ever again and I would prefer not having to desolder the H-power since that took forever to attach.

It needs to find a controller at the expected address and get expected data.

I'm guessing faking that is gonna be really hard.

100 MHz logic analyzer (~$50) to capture the data from a working card and a FPGA devkit (~$50) to mimic it and you're done

TiN says:

Or use FPGA to capture data, so you save on logic analyzer (50$ will get you just a junky one anyway :D).

and that's way beyond my capabilities ATM

Remove Galaxy Power card, throw card away and move on.

Belgium Fraeco says:

It's possible to derivate/send in parallel the SVI2 signal from another running card? Or the signal will be corrupted by long distances or something hoocked on it, so even the running card will go down? I loved your monstrosity Buildz. ^^

United States steponz says:

Lol... card doesn't even in work then.. hahahahaha.. I guess the point is to make a card not work?... because from the way its done.... not gonna happen...........

Chile Samsarulz says:

Looks awesome, but if doesnt work, then is no point showing it, sorry.
