Feels like building a mod-chip for a graphics card. WIP - more to come. Layout done.. some small tweaks necessary. PCB width is too large as well.

Some nice addition for R300 based graphics cards.

The attachment khan.png is no longer available

Finally got to it again, busy times.

Hardware prototype is ready, so some softwareing is inbound.

All on the no-love 9500Pro i repaired. I grew fond of this card.

Quickly hand-soldered prototype:

Mounted on the card using double sided tape:

Added some crude wiring and debug connections:

Card inside the system. Heartbeat is going and card still happy:

Yeah I recognise those speakers by sight. Probably only came with systems or multimedia kits or something and weren't really a standalone product. Coming in an era where everyone was getting "free" 2-7W speakers with their system, this sort included, and standalone sets were higher power.

Just seen this, only picture of them I can find. Looks like a lot of the others sets they had at the time. Also very cheap...

It'll add monitoring to R300, R350 and R360 cards incl. the main voltages, GPU and ambient temperature.. Incl. Rivatuner Support.

I have those cards. Is it to protect them damage, provide earlier warnings?

Yes, it's an easy way to have monitoring for them. It'll not be as good as on RV350 or RV360, as the temperature sensor is not in the die, but on the substrate in form of an NTC, but it'll give a good insight into the cards thermals. It'll also be handy to compare cooler performance on those cards.

RivaTuner lets you slightly overvolt, undervolt, overclock, or underclock, as you deem appropriate, in addition to thermal/power monitoring.

In some versions, it lets you fake the identity of the card so quadro functions can be turned on.

That is not applicable to R300 series cards. As there is no software control for their power supplies. And apart of the XT variants, non of them have temperature monitoring by design. Also non of them have voltage monitoring. Exceptions are some Gigabyte and Tyan models, which provide that functionality through a Winbond chip (found on 9200, 9600 or 9800 cards).

Furthermore I'll have the monitor work in two modes: LM63 emulation, allowing for temperature only monitoring and a custom mode + custom plugin for Rivatuner, which also makes the voltages visible. The LM63 mode will work ootb with RivaTuner, ATITool and Everest Home.

Neat.
