The video card is watercooled, never goes about 40C and idles at about 29-30C. My buddy and I are indeed running the same cards with same settings, even the same bios. I did a driver clean lastnight, and we aren't talking 20 mhz, we are talking from stock to 630 which is 110 mhz on the core, and 20-30 on the memory. The other thing is he is running an AMD 2500+ not the 64 bit but the older ones. He is overclocked on that also, and both have watercooled CPU's. My FSB is about 56 mhz faster, and my memory bandwidth is about double what his is. My system in all respects is faster then his, and his beats mine in benches and in real world gaming. I also have a new problem which may have already been answered in this forum. I have my Core voltage at 1.7 not 1.75 as I had stated earlier. When I run 3dmark 05 or anything 3d for that matter, I can watch the voltage drop down to 1.64, and at a certain point it drops to 0, the monitor goes black, and I have to completely power off and then back on again for the card to come back. I'm assuming that the overvolting is the problem and I may have to tweak mine. I have the OCZ 520 powerstream and my 5V rail is at 5.24 according to mbm, I am going to raise it to 5.5 tonight and test again as I saw someone else did that and it fixed his problem. I just want to know, what else could it be? Also like to add, when I have the memory at 610 my benches, before it shuts down that is, seem to be a few fps higher then they were before, so my core was probably just choking for data from the memory as viper john had pointed out, so now I just have to get it so it doesn't shut down and I'll be happy. Oh yeah, ATI tool gets to 666 on the core before it freezes the system, would running at 645 or 650 be a safe bet below what atitool can reach? Thanks again Urlyin.
