need AGP video card recommendation for older system - please help
Looking for a quality but cheap AGP video card (off eBay) to replace ...
- ATI Radeon 9800 Pro 128MB DDR 256Bit AGP Video Card This is for an old Asus A7V133 system. Any recommendations? |

Since it's Ebay, you could go for a 7600 GT AGP. http://www.gpureview.com/show_cards....1=31&card2=435 That's about $100 for the ones I could find. Newegg has a new (ATI based) HD 4670 AGP for around the same money, but the problem with later generation cards is drivers. (Sometimes there is only one "good" driver, for late model AGP cards.) You always want to check for driver complaints, no matter what card you end up shopping for. http://www.newegg.com/Product/Produc...82E16814161337 The comparison of the HD 4670 is here. http://www.gpureview.com/show_cards....1=31&card2=629 The power drawn by the HD 4670 is around 47 watts. Plus you'd have to add some watts (maybe 5W or so) for the HSI chip. There are limits as to how much AGP can draw, even using a Molex connector. (I had an ATI 9800Pro die, because the Molex connector +5V pin burned on it. I fixed it, by soldering a Molex cable right to the video card, and it worked just fine that way until the card was eventually retired. The burning happened, because of a cheap Chinese Molex which fit loosely when plugged in. My own fault for not rectifying the fit problem when I had a chance.) http://www.xbitlabs.com/articles/gra...b_5.html#sect0 If I had to guess, I'd put the 7600 GT power, somewhere around the same power as the 6600 GT, or about 48 watts. For comparison, some model of 9800 Pro here, is 47 watts. http://www.xbitlabs.com/articles/gra...wercons_8.html Paul |

The video card works but not perfectly (broken lines are sometimes displayed), which is why I wanted to replace the video card. But, if fixing the molex connector problem will get rid of the broken lines, then I can avoid spending for another video card. Is there another way to fix without soldering, which I don't do. Maybe use a better quality female molex connector? |

And that's why it burned. You can try repairing the power connection, then retest and see if any "video defects" go away. Make sure the fan is still working, as many video cards, the damage comes when the fan stops turning, and the heatsink gets so hot the fan body melts. And that's when the GPU gets "cooked". If you're not experienced with soldering, find someone else to do it. Take the video card, and a Molex "Y" cable to a radio/TV repair store, and see what they'll charge to "do the surgery". To do it right, you'd remove the solder from the four holes holding the legs of the connector in place. And then pop the four wires right through the holes. My fix was more of an "I don't care" style repair. Paul |

AGI HP-250NLXAA 250W 60/50Hz ATX Power Supply http://www.ebay.com/itm/AGI-HP-250NL...-/370606177189 You cannot "clean up" a burned connector. I learned this the hard way, on a $6000 piece of equipment at work. Initially, I thought you could clean connectors too, but I was wrong. The machine had an internal defect, and a burned connector. I tried several times to "clean" the pins of the black burnt stuff. The deal is, once the metal changes from shiny and smooth, to heat-stressed slightly whitish finish, the resistance of the pin has gone up permanently. It's like the nice metal finish on the pin is gone. You have to replace both the male and female connector parts, so new shiny pins are present on both sides. On the machine in the lab, I just soldered the two bits to each other, because I was sick of opening the thing up over and over again. Once I soldered the thing, I had no more trouble with it. So instead of pulling the Molex off the video card, I soldered the +5V wire to the backside of the Molex. This was to save me the trouble of using a solder sucker and pulling the solder out of all four of the Molex holes. The other three Molex pins were undamaged. So my repair method was "additive", and didn't involve removing any solder from the video card. Sometimes, the PCB gets damaged while you're removing solder, and I figured I'd avoid that by just soldering the wire (as shown in the photograph). The reason for the hollow vertical metal thing, was so there wouldn't be any wire draping around the pin. By elevating the solder joint, it puts more mechanical stress on the base, where the metal thing joins to the card, and I have to be careful not to tug on the cable too hard. It's to avoid the potential for a short circuit, if I soldered closer to the card itself. The pin and wire carry 5V at around 5 amps on the 9800 Pro. The Molex pin is capable of carrying a bit more than that (perhaps up to 8 amps). But the pin surfaces must be "new virgin material" for that to work. If the pins are damaged, doing a little cleaning on them is not going to make them happy to carry 5 amps again. I don't know where your video defects are coming from. There were some Nvidia chips, were broken solder balls on the GPU caused video problems. If the fan dies on a video card and the GPU overheats, that can cause permanent defects. Sometimes lines on a monitor, are actually a *monitor* problem. It really depends on how the lines look, as to which part of the gear you would suspect as defective. On an LCD monitor, defective matrix drivers on the LCD panel, can cause solid vertical lines to appear on the display. Paul |

However, when the video card was connected to the new Molex extension cable, I got the following message ... "You have not connected the power extension cable to your Radeon 9800 video card Please refer to the "Getting Started Guide" for proper hardware installation !!!" So, I connected the video card "directly" to the power supply, which successfully circumvented the message. But, video defects still exist with the new Molex extension cable. Could the problem be an insufficient power supply? I have the following ... AGI HP-250NLXAA 250W 60/50Hz ATX Power Supply http://www.ebay.com/itm/AGI-HP-250NL...-/370606177189 You cannot "clean up" a burned connector. I learned this the hard way, on a $6000 piece of equipment at work. Initially, I thought you could clean connectors too, but I was wrong. The machine had an internal defect, and a burned connector. I tried several times to "clean" the pins of the black burnt stuff. The deal is, once the metal changes from shiny and smooth, to heat-stressed slightly whitish finish, the resistance of the pin has gone up permanently. It's like the nice metal finish on the pin is gone. You have to replace both the male and female connector parts, so new shiny pins are present on both sides. On the machine in the lab, I just soldered the two bits to each other, because I was sick of opening the thing up over and over again. Once I soldered the thing, I had no more trouble with it. So instead of pulling the Molex off the video card, I soldered the +5V wire to the backside of the Molex. This was to save me the trouble of using a solder sucker and pulling the solder out of all four of the Molex holes. The other three Molex pins were undamaged. So my repair method was "additive", and didn't involve removing any solder from the video card. Sometimes, the PCB gets damaged while you're removing solder, and I figured I'd avoid that by just soldering the wire (as shown in the photograph). The reason for the hollow vertical metal thing, was so there wouldn't be any wire draping around the pin. By elevating the solder joint, it puts more mechanical stress on the base, where the metal thing joins to the card, and I have to be careful not to tug on the cable too hard. It's to avoid the potential for a short circuit, if I soldered closer to the card itself. The pin and wire carry 5V at around 5 amps on the 9800 Pro. The Molex pin is capable of carrying a bit more than that (perhaps up to 8 amps). But the pin surfaces must be "new virgin material" for that to work. If the pins are damaged, doing a little cleaning on them is not going to make them happy to carry 5 amps again. I don't know where your video defects are coming from. There were some Nvidia chips, were broken solder balls on the GPU caused video problems. If the fan dies on a video card and the GPU overheats, that can cause permanent defects. Sometimes lines on a monitor, are actually a *monitor* problem. It really depends on how the lines look, as to which part of the gear you would suspect as defective. On an LCD monitor, defective matrix drivers on the LCD panel, can cause solid vertical lines to appear on the display. Paul Okay, let me see if I can get someone to do a similar soldering solution. If not, it may be better to swap out this AGP video card. The video defects are definitely coming from this AGP video card, which now has a heatsink part attached (since the fan failed). The video defects disappear when another PCI video card is swapped in. |
