| 772271 | 2009-05-08 09:47:00 | Have an old KM400-M2(V1.0) motherboard only ever used on board graphics. Put a new monitor on it but can't get screen resolution high enough for the new LCD. Board can't do it. Got a new SAPPHIRE HD 2400PRO AGP card and once installed gives no signal. The motherboard supports AGP 4 and the HD2400 supports both 4 & 8 AGP. PC has a 430W PSU so that shouldn't be an issue. Have checked the Bios and changed settings to use AGP etc. At this stage thinking graphics card not compatible or faulty. About to see what else I can find around here that has a AGP slot to test in. Any ideas? |

| 772273 | 2009-05-08 09:58:00 | Flashing the BIOS does not make sense. The card sounds as though it is faulty 'out of the box'. It should at least default to VGA upon installation and before its drivers are installed. |

| 772274 | 2009-05-08 10:00:00 | Not yet. Not convinced the update has a fix for it and I would sooner see if I can test the card in another machine before risking a flash. | berryb (99) | ||
| 772275 | 2009-05-08 10:04:00 | Terry that is my thinking as well. It should at least show some signal but there is nothing. | berryb (99) | ||
| 772276 | 2009-05-08 12:18:00 | Find out WHAT voltage the AGP port supports. Some mobos wont work if the voltage (on the AGP port) is wrong. It'll either be 1.5v or 3.0, or maybe both. But if it supports 1.5 and you put a 3v in, it probably wont like it |

| 772277 | 2009-05-08 20:59:00 | Have you tried reseating the card? The slot hasn't been used for a long time and the contacts could be a bit dirty. | PaulD (232) | ||
| 772278 | 2009-05-08 21:12:00 | Also check whether the card does or does not have an auxiliary power supply connector. There shouldn't be a voltage problem, 3v or 3.3v cards are now obsolete, the KM400 has a 1.5v x4X8 AGP slot. I think if the card is 0.8v it will also accomodate or adjust to 1.5 v |

| 772279 | 2009-05-09 00:19:00 | According to this site:www.playtool.com which gives the low down on video card/motherboard compatibility, an AGP 3.0 card with a signal voltage of 0.8 volt will fit into an AGP 1.5v slot but wont work. There does seem to be some confusion over this point though from what I can see. It may be that newer motherboards will provide either 0.8v or 1.5v according to the video card requirements. The Sapphire site does not say (as far as I can see) what voltage the card is, only that it is AGP 4x/8x: www.playtool.com It may say on the box the card came in. |

| 772280 | 2009-05-09 01:03:00 | OMG, I think my brain is atrophying..........selecting 4x or 8x in the BIOS will select 1.5v or 0.8v at the AGP slot. So whatever the BIOS was set to for the onboard graphics, probably 4x, the video card should work, at least as far as going through POST and showing the EPA logo etc, and assuming the onboard video has been disabled. |
