Asus EAH6850 DirectCU Problems

post #1 of 9
Thread Starter 
Hi,

I got this graphics card today as a Christmas present, and it seems to be defective.

I installed it correctly, yet it refuses to run any games, and randomly artefacts all over the screen. I downloaded ATI tool, and it ran in 3D mode fine, no artefacts, no nothing. However when I click, Scan for artefacts, it runs for about 10 seconds, yellow lines of around 20-30 pixels in length appear in the window, which I presume are artefacts.

I have tried reinstalling windows, to clean out any old drivers, and I have installed the latest drivers from Asus.

The card is in my sig rig, replacing my ATI 4670.

Some people say its because of lack of power....this card is meant to be power efficient....needing just 150W to run 100%.....what is the problem. headscratch.gif

Is it my power supply? Is it my graphics card? My power supply is only a few weeks old btw.

Any help will be much appreciated,

PS. Merry Christmas

I guess its your PSU, AMD stated clearly that a 500W PSU is required to run this card.
It doesnt really hurt to go out and get a more powerful PSU, 400 is hardly enough for today's hardware.
You said it refuses to run any game, what the error?

Well, people have told me a 400W is fine for this setup.

I think the more annoying thing is that I have no money at the moment, and so saving up for a new power supply just to have my card not mess up....well sucks.

The games start up, go to the menu, and then as soon as I go into something 3D, it just locks up, and I have to "Control Alt Delete" my way out of it.

400W would be threading on the line for this sys, its not recommended. Remember, you have a quad core there.
You could try to sell this 400 PSU and see if you can top up enough money for a 600W PSU, considering that you need some headroom for future upgrades.
If allowed, ask someone to help to test out the 6850 to make sure that its good, and if it is, sell your 4670 also to buy the new PSU.

Well, my Dad has agreed, if needs be, to buy my current PSU from me for £25. I am also selling my ATI 4670 to him for £20, so I need to find ~£20. Being 14, this isn't easy.

PSU calculator states that 350W is required for this sys, this is the minimum so 400W is not safe.
Its hard to conclude either way so its best to get someone to test your card out for you.
Btw, did you plug in the power cable to your graphic card? some tend to forget this.

This is a 450W power supply rebranded. Also, the power cable is plugged in, yes.
I can't test it out in another system unfortunately, because our house has two old computers with AGP interfaces. Mine is the only one with a PCI Express interface.

Bump. Still having problems, but now it runs the games for about 5 seconds, then gives up.
