 Posted: Fri Dec 14, 2007 5:10 am Post subject: Which graphics card with T&L? |
|
|
Hi guys, I have an archaic mobo D845WN/D845HV with AGP 2x/4x slot(1.5 Volts only). I need to know which nVidia Geforce or ATI Radeon graphics card with T&L capabilities will surely work with my system.It wud be nice if the graphics card has 64 MB or if possible 128 MB memory.But the principal need is T&L and compatibility with my system.
PS- I have P4 1.6 GHz.

I know for a fact that the old MX 440 series will work, but a lot of newer cards will work, such as an ATI Radeon X1650 Pro w/ 512 MB DDR3 in 4X mode....although you probably don't need all that for T&L (whatever that means - sorry if I seem a bit brain dead).
The limiting factor here is going to be you 2X/4X and AGP, and your budget - other than that, you're good to go.

Sorry for coming in so late here - this time of year is busy for me.
You also need to be concerned with your power supply. Many older (and new "budget") computers have PSUs that are barely adequate for the existing load. Newer graphics cards require more power than CPUs!!! So I strongly urge you to evaluate your current PSU status before adding any new hardware.
Use the eXtreme PSU Calculator Lite to determine your power supply unit (PSU) requirements. Plug in all the hardware you think you might have in 2 or 3 years (extra drives, bigger or 2nd video card, more RAM, etc.). Be sure to read and heed the notes at the bottom. I recommend you set Capacitor Aging to 30%, and if you participate in distributive computing projects (e.g. BOINC or Folding@Home), I recommend setting TDP to 100%. Research your video card and pay particular attention to the power supply requirements listed on your video card maker's website for your card. Then look for power supply brands listed under the "Good" column of PC Mechanic's PSU Reference List. Ensure the supplied amperage on the +12V rails of your chosen PSU meets the requirements of your video card. Don't try to save a few dollars by getting a cheap supply. Digital electronics, including CPUs, RAM, and today's advanced graphics cards, need clean, stable power. A good, well chosen supply will provide years of service and upgrade wiggle room. I strongly recommend you pick a supply with an efficiency rating equal to, or greater than 80%.

Ack! Good point, Bill. I completely forgot that my P4 2.0 GHz system with a 250W PSU tried to fry the PSU when I installed my ATI Radeon x1650Pro AGP card in it.

Mine failed to boot, but I distinctly remember smelling a nice, ozone-like (I know that is an oxymoron, but I cannot describe it any other way) smell. Burning circuitry smell, if you will.
It turns out, though, that the PSU wasn't actually bad - just the power draw on it was hurting any chance I had at getting the thing to boot.

Burning electronics has a very distinct smell that, after 35+ years as an electronics technician, I know all too well! 
Certainly, components can get hot enough to raise a stink, yet not completely fail - you may no longer be able to read the paint rings on a resistor, for example, but it still impedes current flow as required. Still, you can count on that component being aged much faster than normal and it most likely is not quite as tight within specification tolerances. If nothing else, it requires closer watching.

Excellent advice. As I no longer use the PSU, and keep it around for testing purposes, (and have another besides that one for testing also) I am not worried anymore.
