Hi.
I have a ATi Radeon X1600 Pro AGP ( HIS version with the IceQ cooling ) . I'm wondering how high could I overclock it , without the risk of frying it .
P.S. I can't monitor the temperatures , because this card doesn't have a temperature monitoring chip or anything.

Well, you can overclock very slightly if you dont know the temperatures, but I would just buy a separate aftermarket cooler. This will give u much better overclocking possibilities and the ability to monitor the temperatures. I reccomend the Zalman VF900, but u can buy a less expensive cooler, since I imagine you wont want to spend 30$ on a X1600.

Damn , I was hoping more than just "very slightly" . Oh well ... with the Catalyst 7.5 , I gained a lot of performance over 7.1 ( oddly , the average FPS in HL2 : LC went from 26 to 36 fps with max settings and HDR ) .
And it seems that the custom cooler from HIS is doing a better job at cooling than the original one from ATI .
So far I've gotten to 520/415 without any artifacting at all ( in the ati tray tool artifact scan , aswell as the atitool one ) . How much artifacting is not harmful ? If I had some way to check the temperature , I wouldn't be asking these questions :P .

It is not very precise but one thing you could try is monitoring power consumption of the system if you have an accurate Watt meter... The heat output is directly related to power consumption so all thing equal in your system you should get some read on the OCing affect on the card. Granted you won't be able to tell if the GPU is at its temp threshold but you could see a change. Just a thought...

Increasing the clocks from stock by 40 ( Core to 540 , memory to 436 ) made about a 2 FPS ( HL2 Lost Coast , everything on maximum 1280x1024 resolution , HDR , AFx16 ,etc. from 36 fps average to 38 fps ) difference . And it didn't seem to be working too stably . I've given up on trying to OC this card ... OCing almost doesn't make any difference at all on this card .
