Claims van Asus dat hun K7V KX133 plankje wél werkt met de Slot A Thunderbird worden bevestigd door tests van Tomies Hardware Gids. Zelfs oude Gold Finder Devices blijken te functioneren, hoewel met weinig succes. De Thunderbird 750 van Tom ging niet harder dan 800MHz. Dit zou ook kunnen betekenen dat snelle Thunderbirds vanwege nauwe timings niet werken met de KX133:
We were in the lucky situation to get a SlotA-version of Thunderbird as well. Officially those will be unavailable to the retail channel and only go to selected OEM-customers. We tried the processor in an Asus K7V with the latest BIOS and found out that this Thunderbird 750 ran without a glitch. However, the overclocking of this CPU was rather unsuccessful. Although the Goldfinger devices work fine with this processor, it was impossible to even overclock it reliably to 800 MHz. This could be due to our sample, but it also could be that the rumor saying that SlotA-Thunderbirds at 800 MHz and above aren't able to run on KX133-platforms reliably has got some truth to it. We will dedicate some more time to this issue and will keep you informed about our findings. We'll also try to find an answer to the question if SocketA-Thunderbirds are able to run in SlotA-systems with special 'Slocket-Cards'. So far AMD stated that those SocketA-to-SlotA cards would not work reliably.
