440LX & GFORCE problem?

[momchil]

I have a ASUS P2L-B motherboard with INTEL 440LX chipset and GEFORCE2 MX400 videocard.
The processor is CELERON-A 533MHz.
The all is work propriety, but when I run some 3D (example 3DMARK) the 3D is work for some secconds and then the application is stoped!
what is the problem?
Is it inposible 440LX chipset and GFORCE to work together?
What must I do?

thanks...

Time to upgrade buddy.

Than ancient mobo probably cant provide the power needed to feed the card with correct voltage.

It is a very well known problem that afflicted many LX motherboards and quite a few Super-7 boards also.

The problem is that the power regulators on the board are under spec, *knowingly manufactured under spec*, because this was an area board makers thought they could cut costs in without people knowing at the time.

(back then most budget systems still used PCI video cards, and when AGP was first introduced the idea was to have only the GPU and a very small amount of memory on the card - the rest of the memory needs would be met by the AGP interface - this is not how AGP ended up evolving).

thanks for the answers...

yes, the problem maybe realy the powerspuplay of the videocard!
when I decrease the core and memory speed to 100MHz the 3D was worked one minute!

What can be the voltage of Gforce power? is it 3.3V?
If it is 3.3V what is the problem?

The problems is not exactly the volt but that your motherboard cant supply enough amps to your agp slot,so when you video card asks for more power (3d games) it doesnt get it & cant perform that task.

you'll have to get a more recent motherboard,a BX chipset mobo should be fine for you & can be found for fairly cheap.

Check the for sale/trade forum right here,there's always someone selling a slot1 board there. 🙂

As I said before it is the power regulators on the motherboard causing the problem.

They may be able to supply 1 or 2 amps at a given voltage just fine, but when something wants say 3, 4 or 5 amps the regulator cannot do it.

The reason why the GeForce is pulling so many amps in the first place is because it is a complex AGP card that includes a power hungry GPU and lots of memory chips which also need power. Like I said before, when these boards were designed, people thought AGP cards would be much simpler, so low power regulators were considered an acceptable hack by board makers especially for the lower end of the market.

Get a new motherboard, and if your powersupply is currently less than 250 Watts it would not hurt to get a new one also. Avoid cheap brands / low end stuff in both cases and you will be fine.
