HD4850 issues....any advice?

Hi all, sorry to annoy you but I have a slight problem and it's driving me insane.

I just upgraded my PC to a Q6600, 4gb 800mhz RAM, an ASUS mobo, and a Hightech HD4850.

All was going swimmingly up until a few days ago my wife was playing her Sims2 and suddenly the graphics went wonky. There are little pixels here and there and some of the graphics look like they're "elasticised" to other bits. Like a big rubber band if that makes sense. I tried out COD4 and sure enough it's on there too so it's not just confined to one game.

I thought it might be the drivers so I updated to the latest Catalyst drivers, still not fixed. I thought it might be a heat issue so I checked it out (besides it has a 120mm fan blowing from externally right on to the card). The card seems cool enough, no impedance of air.

Also the card is seated correctly in the slot.

So here I am, at a loss hoping the fine people of Atomic might be able to give me some tips to get me headed in the right direction.

Thanks.

it's artifacting by the sounds of things. Those cards get a little toasty with their stock cooler so the heat issue might have killed the card.

Take it back get a replacement and watch the temps in the catalyst control centre next time if they get over the top you can adjust the fan speed through the catalyst control centre with a hack

Chipset drivers.

Check for BIOS updates for the motherboard. Research Knowledge Base for the motherboard.

Update the the latest DirectX for your OS - for XP they've been calling it 9.0c for years, but it's had several minor updates in that time.

Knowledge base search - pretty sure ATI has one.

How's the fan going? I've heard some people complain that it defaults to off or very slow - not good. Some newer nVidia cards have the opposite problem - runs at 100% unless you use something like RivaTuner to setup PWM/temp profiles for it.

Next to last resort is a full reinstall of Windows, or pull it and try on someone else's machine.

Last resort = warrantee exchange.

The fan does seem to run a bit slow, but they're so teeny tiny it's hard to tell.

It's a fresh XP install so I know it's not that. It's just weird how it was running fine one minute and "artifacty" the next. The heat was my first thought but there's HEAPS of cool air blowing on to the card.

It'll P me off if I have to return it, but I might have to if I can't fix it. I wouldn't have thought a game like Sims2 would have taxed it enough to instantly cause artifacts......

It may not have, but the default fan setting for the HD4850 are a little low, coupled with the single slot cooler it's a recipe for your card running to hot.

You know, the straw that broke the camels back?

Yeah, I just checked the CCC and it's only running at 75deg so it's not TOO bad but still not optimal. Might have to ring the seller and see about a replacement then put an aftermarket cooler on it.

It's probably the best solution all things given it does sound like the card is faulty. Unless you want to test it out in other system first I'd be sending it back, if you've recently bought it then they might just give you a replacement

Yeah I might ring them now. I think I was just after someone else to say "take it back".

Cheers.

EDIT: I just rang them and they said "Bring it in Monday and we'll test it". Grrrrrrrrr

"Only 75" is kinda hot if it's just idling in 2D.

For 3D stuff, count on most cards doing anything from 10-30 more.

75C is very very hot. My 4850 is idling at about 54C and shoot up to 65-80C during heavy gaming.

I'd get that back to the manufacturer for a replacement.

75c!
fuck, that's hot for just your idling temp - I got a 3870X2 and that idles at 38-39c - doesn't matter how hard I push it, it's never reached anywhere near 75c.
it sounds like the cooler isn't seated properly - how hot is it to touch? it should feel very hot. if the heatsink isn't as hot as it should be (somewhere around 75c) then, it isn't seated properly.
I'd opt for a new one anyhoo - if it's idling at 75c, it would be hitting in excess of 100c at full load - god knows what damage that's done!

Yeah, sounds like a dodgy assembly issue with the heat sink not cooling the GPU.

Before you take it back try the fan mod doing the following (don't worry it wont void warranty)

-open catalyst control center adv mode
-unlock ati overdrive
-go up to the top and make a profile name it whatever
-then go to c/your computer name/app data(need to enable view hiden files)/local/ati/profiles/whatever it was called
note: step 4 could be different i am just going from memory, you could always search for the profile :)
-open the profile in notepad
-scroll down till you see "automatic" and change it to "manual"
then go to target fan speed percentage and set it to about 35 and save
-now go back to CCC and load your profile, if done corectly the fan will speed up

now try it on a game and see if it artifacts.
