ATi cards always flickers when startup, even the first time i used 4870 last year it flickers upon startup...having said, I think all the ATI cards I used within 3 years ago does flickers upon startup...
I think it's how CCC is commenced in the processing...
Probably the airflow of the casing, because mine idles around 40c~42c @157/300 either day time of night time (and early wee morning), the room got no aircond., and it's freakin' hot in the daytime..
Using ref. cooled PowerColor 5850. (replaced the thermal pasted with
Tuniq TX-3)
BTW, I'm using Lancool PC-K62 with 2
14cm fans in the front (intake), 2
14cm fans for top exhaust and2
12cm fans for rear exhaust.
Only drawback with much airflow in the casing is that you have to vacuum cleaned the casing once a month, too much dust...
Anyways, idle temps below 50c (@157/300) should be standard, above that is considered a bit warm..
hm how did you get 2 fans for the rear exhaust ? I am using Lancool PC-K58 which isnt that much different from the K62. I use 2 14cm front intakes (default lancool's and
), 1 14cm thermaltake top exhaust, and 1rear exhaust which is lancool's default.
The only thing I didnt change is the thermal paste lol and like the other forummer said, flashing the card's bios, which i am not so confident ;p
