Hi! I'm currently having several questions for which i'm expecting some answers.(please ) I own an Club 3D X1600 pro. Since i don't want to upgrade anymore , and i have plans to go on xbox360 area , i just want to squeeze as much as i can from this card. I touched somehow a limit right now , by overclocking it. The default frequencies were at 500 Mhz for the GPU and 500 (1000 effective) for the Mem. Right now , thanks to a bios flash with the original modified bios , the frequences have been increased to 580 Mhz for the GPU and 630 (1260 effective) for the Mem , using stock cooling. The card is stable at these freqs , but i was wondering if i can get more out of it. A thing i forgot to mention : i don't know at what temperatures is the card working , since it doesn't have a Temp sensitive diode(at least that's what i think , cause there's no software which can show me the temps. Not even Ati tool). Now , the questions : 1. Will i be able to overclock it much higher if i buy an Zalman VF700CU cooler? (because if i set a freq of 590 mhz on the gpu , the card freezes. As for the memory , if i try to get closer to 1300 mhz , i get artifacts, and i don't think this is normal for GDDR3 mem chips. 2.As i said above, the memory chips are GDDR3 , 128 bit , made by Hynix. If it helps , there are some serials on the chips : HY5RS123235 /FP-2 /638A /Y7ED2757TQ . I would like to know the maximum frequences supported by this memory type.(if anyone could find out) 3. I am totally confused. Confused by the result of the Ati Tray tools benchmark. With the default freqs i was able to get only 2322 points , but with the new freqs i get 2 x stock and a little more? 5010! I did the test 2 times , and the 2nd time i got 4980 points. Is this normal? I just don't know what to think about that. 4. Moving back to - might this be produced by a lack of power , which means there's a voltmod required? including the zalman.. P.s. if you guys need to see the card , i can make some pictures with it , having the cooler mounted/unmounted.
