Does anyone have any information regarding video card compatibility with an AGP PRO 50/110 slot on TYAN Thunder K7X pro motherboard? This is a server board, and the AGP slot is longer and accepts AGP cards with different configurations. I just haven't figured out which cards are compatible with this slot.

Brief expert summary: an AGP Pro slot is simply a longer AGP connector that adds power pins so workstation cards can draw more current (the Pro “50” and “110” numbers refer to the extra wattage capacity). AGP Pro motherboards normally accept regular AGP cards, but AGP Pro cards will not work in plain AGP slots — and voltage/keying (3.3V vs 1.5V/0.8V) still matters for compatibility. (playtool.com)

What matters for the Thunder K7X Pro: the board was shipped with an AGP Pro 4x slot (so it will physically accept many regular AGP cards and also Pro cards sized for the same variant). The official manual and contemporary reviews call out that extra-power wiring and special power connectors on some server boards can affect what the slot actually supplies, so confirm whether the board is wired as Pro-50 or Pro-110 in the manual before trying high-draw cards. (pcper.com)

Why saw beeps and how to proceed (concise troubleshooting checklist):

  • Inspect the card edge for the AGP notch/key positions (voltage).
  • In BIOS, force a conservative AGP mode (1x/disable fast-write) if available.
  • Try a known low-power AGP card first to confirm POST.
  • Update the board BIOS to the latest TYAN release before testing newer AGP cards.
  • Verify the system PSU and any vendor-specific motherboard power connectors (some TYAN/server boards require special wiring or stronger rails).
    These checks address the most common causes (voltage/key mismatch, BIOS/init issues, and insufficient power). (playtool.com)

Final notes tied to the thread: ’s caution about voltages and newer x8/x4 compatibility is on target — some combinations physically fit but won’t operate at the expected speed or voltage. For the cleanest result on a Thunder K7X Pro, either use a documented AGP Pro workstation card that matches the board’s Pro variant or a simple, low-power regular AGP card that matches the board’s signaling; if problems persist, list the exact card model, BIOS version and beep pattern for narrower diagnosis.

Thanks for the reply! Ihave tried one other regular AGP card which gave me a beep code and prevented my PC from booting. I took it back out and the PC booted back up just fine. It could have been a driver problem, though. I haven't tried anything else. I have found and ordered a couple of cards to fit the pro slot, one 64mb and one 128mb. As soon as they arrive I will try them. If they work out OK I will just use them for now, but I do appreciate you taking the time to reply.

your welcome .i think you have to be careful with the different voltage of newer faster cards , and x2,x4,x8 agp cards,some 8x cards aren't backward compatible ,been my experience anyway .
