Hello.


Well, after i returned my system for repairs, the new cards worked relatively well for about a month.

Then I decided to test games like Crysis, and UT3.

I assumed it was my CPU overheating. After putting in various cooling measures, this did not solve my problems. Only today did i realise my gfx cards were overheating. After the crash, i turned on my PC and the fans were running full blast, and the temp was about 70c when it is usually 30c, and that was just when i booted.

My cards overheated to the point that the PC crashed giving me this screen.




(The colour alternates and patterns change)

My drivers are fully up to date, and my system is relatively clean of dust.

Any help guys?

RIG details:

AMD X2 6000+ @ 3.12ghz
Dual 4850's in CF.
17" screen.
4gb ram.
Gigabyte MA790HP-DS4H mobo.
 
Hi, try going to CCC>OVERDRIVE> PRESS DEFAULTS>APPLY>OK see what happing's.

l had trouble with auto-fan / temp's Sapp ATI 4850-

This model -http://www.legitreviews.com/article/730/1/

Came across a thread when l googled it, and a guy flashed his l think it was a MSI ati 4850 with the ASUS ati 4850 bios, so done the same with mine. Now it idle's at AV=49c / load AV= 68c thats with a OC GPU-675 / MEMORY 1100-MHz stock cooler no prob's at all auto-fan works load 48% been like that for some time, don't forget you flash your card at your own risk.

Just google how to use ATIFLASH, sorry l did not keep the instructions.
 
My 4850 has always run at 81C with the fan on 50%. I thought that was just normal for them... or is something wrong with mine?
 
Nope, 81C idle and it goes over 100C when playing games that aren't even that demanding, like Neverwinter Nights 1. When it goes over 100 I just stop playing. xD
 
I had the same problem, i tried all sorts, new bios's, turning fan upto 100, even adding a 120mm pointing directly into the flow of the graphics card, and i was still idleing at 80, load 120 which is borderline acceptable.
Next i took the HSF off the card and was surprised to see all the thermal paste brown and solid, as the heat had basically cooked it, cleaned it all up, slapped on some AS5, and now im idling at 41, and load 67, auto fan never goes above 47%.

Wow, how d'you do all that stuff that you did then?

I'm a noob to all of this.

In any case, I may RMA my cards, in favour for a Visiontech 4850, due to the lifetime warranty.

Are they a reliable brand, how does their cooling measure up, and, if anyone owns that specific card, is it any good compared to other brands?

Going from the stock fan on 50-65% all the time, I can barely even hear this one. To sound like this I think I'd have to have the old fan on something like 20%. I'm actually amazed at how much cooler and silent it is
